that dogs must have memories because for
instance, if I scold and hit my dog today, in 3
days, if I raise my hand, even if it's not to hit
him, he will most likely cover. So, this is
because he remembers what I did, right?

completely mix, I wondered if the moving surface
currents in the ocean sped up the cooling
evaporation process and cause the thermoclines in
the ocean to mix faster as well. Does moving
water evaporate faster than still water?

| 173: | Hi, I have a question regarding contradictory
properties between lithium's first ionization
energy, which would make it the hardest of the
alkali metals to lose an electron, and lithium's
position on the reduction potential table, which
puts it as the most reactive metal. Could you
help explain this seeming contradiction? Thanks.

can be used as indicators for acids and bases.
It said that the lichens in the acid (apple cider
vinegar) turns red, and it turns blue in the base

other science teachers say that they've tried
this experiment too over the years, and it's
never worked for them either. Why not? (It's
frustrating the text recommends a lab that
doesn't work!)

if they can, will the liquid hinder their travel
or aid it? Also, someone once told me that

airpumps? It would be great if you could
answer my questions whenever you could so I can
complete my power point presentation for my 8th
grade science project. Sincerely, Denise

| 266: | Our AP Bio class is studying taxonomy and how
different species are grouped together. Our
textbook introduces the concept of grouping
everything into three domains, but it's a few
years old and implies that at the time of writing
it's not sure how things will end up being
classified. We were wondering if there are any
"kingdoms" under the domains of Archaea or
Bacteria. Also, under the Eukarya domain, in
addition to the kingdoms of Animalia, Plantae,
and Fungi, it has several "candidate" kingdoms
consisting of the other eukaryotes. Are these as
yet actual kingdoms? Internet research has been
confusing, as different sources list anywhere
from 4 to 10 kingdoms under the three domains.
Is there an "official" way of classifying things
as of yet?

| 315: | I am currently working on a science project for
a county competition. I was wondering if you could
either direct me to someone who could help me in
the subject that I am working on or provide some
information that could help me if you had the
time.
I was developing the idea of
testing what variables change reproduction rates
in bacteria or mice. In this experiment a control
would be normal conditions and the rate of
growth in these conditions. By limiting food or
developing competition / a destructive event, you
can measure how these variables can effect
reproduction. What seems most interesting in this
experiment, though, is what might happen if it
would be applied to mice. It can be tested
whether or not mice would still reproduce if

| 316: | My partner and I must do a demonstration for our
AP chemistry class on 3/19. We have chosen to do
a breathalyzer reaction. We are going to compare
how the indicator reacts with vodka to its
reaction with beer. We have all the materials,
and we have followed the directions carefully.
However, we have had major problems getting the
reaction to occur quickly and noticeably enough.
We have had problems with step 3 (getting the
gel) and 16 (making the reaction happen).
Initially, the reaction was slow. The mixture we
used was supposed to turn from orange to green.
Instead, it turned from yellow to clear with some
blue tints, taking over ten minutes to complete.
After experiencing this twice, I added a few
more drops of potassium dichromate and was able
to make the gel orange. When I added ethanol
(about five drops of vodka), the reaction was
slightly more noticeable. Putting several drops
of the ethanol directly onto the gel changed it
to green/blue in a minute or two. This was
better, although still not fast enough. My
partner and I tried again to see if we could make
the reaction faster by adding even more potassium
dichromate solution. Instead of obtaining the
desired orange gel as I had done before, the
mixture was mostly a yellow liquid with only
slight gelling. Adding more sulfuric acid and
sodium silicate did not seem to help. My
partner and I need to get the reaction working
well very soon so that we can have an interesting
demonstration for the class. We are looking for
a gel that will completely turn green in a pipet
in about a minute when ethanol from a balloon is
blown into it. We would like to compare this
with adding beer through the balloon. Why did
the mixture stop gelling and turning orange
despite all the trials and adjustments? What can
we do to get an orange gel that will work well,
as I described?

| 318: | Dear ScienceLine, I have a project idea that has
to deal with mice and/or bacteria and what
factors may lead to lower reproduction rates. The
main idea in this experiment is to see if the
organism will reproduce even when there is too
little food to support the offspring. I will not
do any testing in mice, but will definitely be
testing bacteria. The question that I have now is
whether or not it would be better to work with
fruit flies or worms. The main reason why I was
considering mice before was the fact they
probably have a higher thought process than other
animals that can be tested. I was wondering if
fruit flies or worms would react in a similar way
or if I should just test both.

| 389: | How can a star be formed? From the big bang the
collapse of gas clouds under gravity is supposed
to generate the heat required for nuclear fusion.
However, a gas cloud would be too hot and the
outward pressure would prevent the collapse. I
understand that molecules in the cloud collide
and radiate enough heat away, but according to
the theory, the bang is made mainly of hydrogen,
with a little helium with other elements formed
inside stars. Helium can't form molecules at
all, so the only molecules formed would be
molecular hydrogen. Even this is easily
destroyed by ultraviolet light and needs dust
grains to form.
You and I know dust grains require heavier
elements. The only coolant left is atomic
hydrogen, and this would leave gas clouds over a
hundred times too hot to collapse.

wanted to plate it with chrome, but I was

UCSB. I am working toward becoming a science
teacher. I am constructing a lesson that I will
give to secondary school students. I would like
to ask your advice/feeling toward creating a
lesson based around the achievements of Ben
Franklin. Ideally the lesson needs to be about a
scientist who differs from the traditional
representation of scientists. Do you think Ben
fits the traditional model, or do you believe the
achievements he made sets him apart form the
stereotype of a scientist who is a white male,
and is detached from society. Your prompt
response would greatly be appreciated, along with
any suggestions you may have toward designing my
lesson.

| 550: | Let's say you have a copper plate. The copper
plate is at 30 degrees celsius. That's 86 degrees
fahrenheit. Why is it that air at 86 degrees
fahrenheit doesn't feel as hot to your skin as
copper at 86 degrees fahrenheit?
Another
aspect of my question: Heat is the average
kinetic energy of a substance, average
translational energy I believe, ie the motion of
the particles, in a gas the particles have
kinetic energy, and move about chaotically, and
collectively this energy is the substance's heat
energy/internal energy. In air, the particles are
free to move as described above. In the copper,
the total heat energy of the particle is
described by the average energy of the particles,
which i suppose are vibrating, not moving about
translationally.
So let's say you have your
copper plate at 86 degrees fahrenheit, and you
have a certain volume of air at say 80. The metal
plate will warm the air, transferring heat, until
the air reaches 86. The whole system will
probably settle at a common temperature of like
83 or whatever, and in reality it would
eventually just reach a lower equilibrium as more
and more heat dissipated. But I don't know if I
am correct in this.
It seems like the copper
plate at 86 degrees is much hotter than the air
at 86 degrees, and the plate will continue to
dump heat into the air. Maybe I'm wrong.
What about water? What if you have an 86 degree
copper plate in contact with water at say 84
degrees. It just seems to me like the plate feels
much hotter than the water, yet it would seem
thermal equilibrium would tell us that the copper
plate will only heat the water two more degrees,
and then no more heat transfer will occur. Is
this correct? Thank you very much for your help.

following question: How do we measure true mass

but I find that a spring scale gives the same
answer. If, on Earth, a 100 g object weights
approximately 1 N, it's mass should be 100 g on a
balance, but not a spring scale. Yet I get 100 g
on the spring scale as well. I have not found an
answer to my quandary so perhaps I am not asking
the correct question. Thanks for your help.

| 622: | Dear Science Line,
It seems like I sink in the swimming pool if I
make a canon ball shape out of my body. It also
seems like I float better if I spread out with
out stretched arms and legs.
My thinking is this: Because Density is Mass/
volume, if you make a cannon ball shape out your
body you are not decreasing your volume. Right?
I suspect that there is a buoyancy change
relative to my now different surface area and
that density is not the issue. Mr. Mann thinks
it has to do with my volume changing due to my
inflated lungs, thus affecting my density.
Question: So...... Why do I sink if I make a
cannon ball shape out of my body? Who is right
Mr. Mann or me? Major boasting rights at stake
here so we would appreciate your attention to
this as soon as possible.

petroleum not affect the kelp, what does the kelp
have to make the petroleum not stick to it when
the petroleum sticks to feathers and kayak paddles?

| 681: | Hey, I was recently talking with a friend about
alternative fuel sources (maily for automobiles)
and primarily nitrogen. I am not 100% sure how
the nitrogen that is used for nitrogen powered
cars is obtained, but my friend thought that it
is usually just taken from the atmosphere and
purified. This is what brought about my
question, as we then got into a discussion as to
what would happen to the atmosphere if nitrogen
powered cars became very popular, and the
nitrogen was just taken from the atmosphere. My
friend pointed out that if this became the case,
that since nitrogen makes up a considerable
amount of our atmosphere, something would have to
replace it's void if we were to take a percent of
it out of the air. He then presented his two
opinions on what would happen: 1. Oxygen, or some
other gas, would make up a larger percent of our
atmosphere to replace the void of the
disappearing nitrogen, and in the case of oxygen,
we could suffer from oxygen intoxication if the
percent of it in our atmosphere became to great.
His other opinion was that, if nothing was able
to replace the nitrogen, our atmosphere would
more or less implode. So my question is: what
would happen? Because after we discussed it a
little further, we realized that the second
opinion might not be right, given the fact that
space is void of all matter, and therefore could
not make the earth's atmosphere implode. Thanks.

| 685: | I am doing a science project for school and am about 90% sure that I would like it to be in the field of light dispersion (of rainbows). I have done some research on it, but I am indecisive about what the variable should be, that would create the more advanced and better project. I could change the size of the drops, take a digital picture of it, and measure the changes of the angle (between the incoming ray and refracted ray) on the computer. Or, the variable could be liquid, and I could observe how different indices of refraction affect the same angle as above. A third choice I have is to change the drop size, but I do not know how to do this precisely. A last project I am debating over could be to see how any one of the above variables affects the brilliance of rainbows. I am open to any suggestions or new ideas. Thank you!

standards: Standard #6 a)Carbon, because of its
ability to combine in many ways with itself and
other elements, has a central role in the
chemistry of living organisms. b) Living
organisms are made of molecules largely
consisting of carbon, hydrogen, nitrogen, oxygen,
phosphorous, and sulfur. c) Living organisms
have many different kinds of molecules including
small ones such as water and salt, and very large
ones such as carbohydrates, fats, proteins, and
DNA. The labwork we do always gets into the
chemical structure of the molecules and how they
interact on a very basic level. Thank-You for
any help you may offer.

| 771: | To whom it may concern: I am entering the Science fair this year, and i want to submit a marijuana-based project. I was wondering if you could help me. I am trying to do a science project on marijuana. I have worked so hard to get this project approved. It took three tries to finally get the ok, so i can just do research. I have talked to many different sources on how to get marijuana to study and do my experiment on. Doctors say that no respected physician would just give marijuana to a sixteen year old girl. They don't want to liable they say. I am not willing to get marijuana illegaly, because I knew from the start that it was not a risk I was going to take. I was told that if I would even have a chance to do this I needed to contact a professor who works with it. I was wondering if UCSB or any other university in California had anyone that could help me out? Thank you Sincerely, Vivian Voodoochile118@yahoo.com

animals on the Channel Islands.
After
learning from Dr. Atwater about the geological
origin of the islands and their trip up from the
San Diego area by way of plate movement I became
curious about the Torrey Pine being in both the
San Diego area and on Santa Rosa Island.
Does this mean the pines traveled up on the
island?
Could this also mean other plants
made their way up in the same way?
Are there
certain plants that did not exist at that time
indicating a trip across the channel the only
logical explanation?
Might animals have
traveled up on the island the same way or is
millions of years too long ago for contemporary
animal species?
What animals other than the
Pygmy mammoth were once out there but are now no
longer around?
We are studying about plant
and animal dispersal and the effects of island
isolation on these plants and animals and these
and other questions arise. We are aware that
certain conditions must be present for a plant or
animal to establish itself on the island but we
would like to know if there is any evidence of
species being there but not making it to present
day, either due to climatic changes, predation,
influence of man, or some other reason.
Any
information or direction towards sources would be
greatly appreciated.

effects of temperature on viscosity of honey. My
experiment doesnt seem to work and I need help to
modify it. My method is:
Method: 1) Put 5
ml of honey into 4 separate beakers.
2) Make
sure the temperature of honey in all four beakers
is different by using hot water bath to get it to
a higher temperature and ice bath to lower the
temperature.
3) Label each beaker 1, 2, 3 and
4 and measure the temperature of honey in all the
beakers.
4) Dip a paper clip in the beaker for
five seconds and place it on separate evaporating
basin.
5) Use a magnet to pull the paper clip
right above the evaporating basin.
6) Using a
stop watch, record how long it takes the paper
clip to drop onto the evaporating basin.
7)
Do the same with beaker 2, 3 and 4.
8) Repeat
steps 4, 5 and 6 three times to get an
average.
I think methods numbers 5 and 6 have
problems. The paper clip does get attached to the
magnet but it doesnt drop back.

student teachers conduct a toxicology
investigation following a standard protocol. They
investigated the effects of a toxin of their
choice (diet Pepsi, nail polish remover, etc.) on
the germination and growth of lettuce seeds.
They used six different concentrations of the
toxin, three plates per concentration, five seeds
per plate. They counted the number of seeds
germinated per treatment and measured the length
of the seeds' radicle in mm. My questions: (1)
What is the appropriate number of significant
figures to use when calculating the average
germination and average radical length? (2) If a
seed hasn't germinated or has germinatd but has
no radicle, do you include a 0 for radicle length
when calculating the average or do you leave it
out of the calculation all together? Thanks much
for your help!

(actually, it's energy in general, but I prefer

know if something like the following would be
possible. I have three ideas, one that I'll test
as soon as I get the supplies, another simple one
that's a super back up plan, and this other thing
that I'll try to do if it's even possible on
earth. It's basically an attempt in transferring
an electrical charge from one end of a wire to
another. The hitch is that the wire has at least
a free inch of space between two wires. So, to
attempt to allow any amount of the charge to
reach the end, I'm using a series of magnets.
Another way would be to send a huge charge
through a thick wire and form a weak magnetic
field around the area of which the charge would
be making a 'free fall' through.

tube valve to let air out. Inside the tube there
is a piston that was supposed to move back and
forth. It didn't move. We think the valves don't
let enough air into the two inch cylinder. We
started to fool around with the tube and put a
plastic golfball in. We connected a bicycle pump
to one end and left the other end open. When we
pumped air into the cylinder, the ball did not
shoot out as we expected. It shot back quickly
against the end where the air was coming into the
cylinder. Why didn't our piston work, and why
does the ball come back and not away from the
air? This is fun science. Thanks for your help.

| 1237: | Hey, my name is Kimberly and I am right in the middle of the Science Fair. I am required to have an interview with someone who is an expert or knows about my research topic. I was wondering if I could ask someone a few questions about my topic, like an interview.
My question is: Can I make a pH indicator by using vegetables?
Now that you know my question, here are some questions for anyone who can answer them.
Q. Is there anyway to test if a solution is a salt?
Q. Many plant materials, such as red cabbage, contain compounds that are indicators. What compounds does Red Cabbage contain?
Q. So far, I know of 7 acids (sulfuric, Nitric, Hydrochloric, Citric, ascorbic, carbonic, and phosphoric). How many acids [estimated] are out there?
Q. Which acid is the most deadly and where is it found?
Q. What is the definition of corrosive?
Q. If bases can harm skin, and if your hands being to feel slippery you should immediately rinse your hands with large amounts of water because you might have some sort of base on your hands, then why aren't we harmed when washing our hands with soap?
Q. What are some other plant materials that can be used as indicators or have some compounds that are indicators?

hormones, estrogen and progesterone, and these
stop ovulation, but keep the rest of the cycle

mesh structure. Everything that is happening so

there is red settlement of the floor. I would
greatly appreciate any feed back into what's

P.S. Someone suggested that it may be galvanic
corrosion. This may be feasible because the
steel is galvanized (I'm assuming that that's
what's on the steel to stop it from rusting).

| 1307: | Thanks for responding to my question, I have a few more if you'd be so kind as to answer them. First, the titanium anode didn't corrode at all, it was the steel cathode. But by being the cathode, wouldn't it have cathodic protection from corrosion? Also, we just studied electrochemistry in my chemistry class. From this knowledge, I am assuming that the positive calcium and magnesium ions in the water are being reduced by electrons supplied by the electric current, but what makes them electroplate on the steel structure and not the walls of the tub as well? And where do the carbonate ions come from? I didn't know that they were present in sea water. Each subject received the same voltage, but a different amount of current (6v:300mAmp, 400mAmp, 700mAmp), would the total kilowatt hours be the same for all of them? And why would the current make a difference?
|
|---|
| 1308: | In my school science project, I have a submerged steel mesh structure and titanium mesh strip. There is a charge running through this seawater, the titanium's the anode, and the steel mesh is the cathode. From what I already know, the current through the sea water causes the dissolve carbon dioxide to become carbonate ions and attach onto the cathodic steel mesh structure. I was hoping someone could give me the balanced chemical and redox reaction for this process. The steel mesh structure is rusting so maybe this has something to do with it? I didn't really understand the answer to why the cathodic steel mesh structure rusted despite being the cathode nor why the calcium carbonate formed on the steel structure instead of just anywhere.

read that they bite humans in the night for
blood, and in fact I did have a few bug bites on

activity or is it a natural occurrence? How can
this global warming result in a runaway
greenhouse effect and what can be done to stop
it? How will an increase in volcanic activity
affect global warming? Will we be in for global
cooling and another phase of the ice age?

They looked a bit like pumpkin seeds or big lentils. They were about 1cm in diameter. Sort of disc shaped. In a clump there may have been 30 or 50 of these "shells", loosely stuck together in a kind of clear slime that looked a bit like saliva. Some of them appeared to be opened that is two halves (upper and lower) of the disc had split away from each other. Often they were lying on gravel in the sun and were not hidden under any vegetation. I regret that I did not take a photo. I have searched the internet looking for photos of lizards' eggs, as I thought this is what they might be. However I am not at all sure. If you have any wildlife expert who could tell us what these might have been I would be very grateful.

Each scope has the list of specs and someone like you would know the meaning, but its foreign to me. When I went to their other items for sale I found the motor for $50 (if it is the same one) so perhaps the money is in the larger mirror like you said. Is the larger field just to make it easier to find your target? It appears the difference in magnifiication is 1000 vs 1400. Is that a lot?

b) How effective are the chemically produced ones for each of them compared to the ones extracted naturally? Are there any harmful effects using the chemically produced ones?
c) In the market ,if one does not know the origin of a particular oil, how likely are each of them to be produced chemically as compared to be natural?
d) Apart from laboratory tests, are there any other way of distinguishing between the two?
e) When the lid is taken off a bottle of the oils, the oil evaporates to fill the room with its aroma. But after sometime, no more oil evaporates unless one stirs it. Why is it so?

| 1544: | A group of students and I have designed, funded
and built an alternative energy unit. This unit
consists of a solar cell and a wind generator
(PMG). We are attmpting to determine which
method of alternative enregy production is best
for our local area. We are trying to measure the
voltage produced by each device, along with a
voltage drop across a shunt resistor to
calculated the amperage from by generators. With
these two quantities we are able to calculate the
power each produces. We are using Vernier
Softwares LabPros and LoggerPro 3.4 on a laptop
PC. Our problem is that when more than one
voltage probe is connected, the readings that are
recorded are bogus. When only one voltage
detector is connected, the readings are spot-on.
We have worked with Vernier and tried several
different voltage probes. The same results. We
believe the problem is the common connection
through the LabPros. There is no one negative
ground. How should we change our detection
circuit to get good readings. Please see our
website for pictures and details. URL:

What is the energy/speed formula? In other words, given the mass of an object, how can you calculate how much energy you would need to accelerate it to a certian speed?

comets or goldfish in a swimming pool converted
to a pond. They are about 5 inches or so long at
about 1 year of age. Very robust and active. Four
of them are basically white. Of the four, two
have some deep orange spots naturally on them. I
just noticed today that the white on the fish is
turning a washed out yellow/orange color. They
were seemingly pure white before. Now fins and
head particularly are turning organish. I'm
worried about their health. One website that
sells koi food says this is due to liver
function. Can that be correct? If so, what do we
change? We are feeding Tetramin and a special
koi food. We are in Hawaii so the
temperature is in the 80's. Full sunlight on the
pool. The pool is about 15,000 gallons with deep
areas at 8' on one end. The water is not
filtered, aerated or treated in any other way and
is very green as my husband is under the
impression that it is a large enough body of
water to not need extra care. We have two water
hyacinth plants in with them. The fish eat the
fish food, algae and bugs that fall into the
water. The comets/goldfish we bought were sold as
feeder fish" and we put them into the pond when
they were only a few inches. They are now robust
in girth, about 5 long in the body and very
active. But I wonder what this symptom may mean
in terms of nutrients and water quality?

it was just that more force (centripetal force)
was acting on the plane. Here is where the
question arises. The plane appeared to have
weighed more, but when a person sends an object
into circular motion (for example swinging a
hammer in a circular motion and then throwing it)
the object appears to the thrower to be lighter.
Why when the object "weighs more", does it feel
lighter when being thrown?

| 1723: | Hello! Thanks for helping me before with my
questions, I am wondering about the possibilities
of time travel, and my teachers can't help me.
So, here it is: If, theoretically, some
one was able to travel faster than the speed of
light, thus, theoretically, traveling back in
time, would it be possible to get those effects
or results gravitationally? In other words,
instead of reaching a certain speed to reverse
time, the person stays in a very large gravity
field to do that time dilation. So, if you had a
large enough gravity field could it actually
reverse time, doing the same thing as if you were
traveling faster than C? If not, why? If so,
why/how? Is there a formula to calculate that?
Could it be done using an artificial
gravitational field?

| 1731: | Hi! Thank you for helping me with my previous
questions, I was wondering if you guys could give
me some insight on the following. We all
know that electrons create tighter bonds between,
or in, substances. Electrons are found in
electricity, as a matter of fact, electricity, or
an electric current, is basically a stream of
electrons. So when talking about something like
ionic or metallic bonds, if you were to pass an
electric current throught a substance, most
likely a metal like copper or metal foil or of
some other sort, would that significantly
increase the materials strenght? I have heard
that metallic bonds do contribute to somethings
strenght and many other things. If not, why? If
so, could the phenomenon be controlled, for
example, increasing or decreasing the additional
strenght of the material by increasing or
decreasing the electric current passing throught
it? How could I produce this phenomenon in a safe
experiment, how should it be designed? How
significant would the increase in strength be
given the metal, could I calculate that? Would I
get the same results as passing electricity
throught a material if I simply charged it with a
given amount of electricity/electrons? What metal
or other material would be the best to use? Is
there someother was I could increase a materials
strength besides this way?

I have a very bright 8th grade
student who asked me something I can't
answer. If one were to put some sort of
mechanism underneath a big rock that converted
the pressure of the rock against the earth into
electricity, then how is that not some sort of
perpetual energy source? The gravitational
potential energy is not changing if the rock is
not moving; yet the pressure it exerts must be a
kind of energy that can be theoretically
converted into electricity, no? The gravitational
energy does not "wear out" in this situation...
so isn't that a perpetual energy source?
I'm just not sure how to answer his question.
He and I both think we understand the basic
concepts of gravitational potential energy and
kinetic energy. Any guidance you can give us on
answering his question would be most appreciated.
thank you!

| 1801: | Hi! I hope everything has been going well. I
need some help on the following:
I want to
calculate the amount of force on a NdfeB magnet.
The amount of force on each particle (or atom) in
the magnet is 0.000000000065024 newtons. to
calculate the atoms in the magnet I did:
grams/10.811 (10.811 is the atomic number of
boron) which equals 37.85958746. Next, I
multiplyed that by avagadros number: 37.85958746
times (6.02214 times 10 to the 23 power)and I got
2.27995736 times 10 to the 26 power. when I
multiply the number of atoms by the force on each
atom I get about: 1.482656617 times 10 to the 16
power newtons. That is A LOT of newtons! I dont
understand why I am getting so much for just a
magnet. I dont know what I may be doing wrong. I
hope you can help. Thanks. Hello, I have
some more information regarding my force problem:
The dimensions of the magnet that I am using are:
1.5" by 3" by 3/4" This is how I got 6.5024E-11 N
of force per atom: I used this formula: F=qv
times B f= force q= test particle of charge, q at
rest that point (proton, I believe) v= velocity
of particle sin= angle of particle or B, in other
words B = 12700 guass times (10to the power of -4
tesla divided by 1 guass) = 12.7 tesla, B= 12.7

10 to the -19 power coulombs times 32000000m/s

They are not compatable with the second question I asked you, about the formula to calculating the diamagnetic force created by bismuth. So, if you can direct me to any information or if you have a formula that I can use to calculate the diamagnetic force created by bismuth it would be a big help. I was wondering if I could modify a formula for calculating magnetic force and use that for bismuth, but you guys know more than I do, I would really appreciate the help. So, I guess my question is to put it simply, What is the formula for calculating the diamagnetic force created by bismuth? (at certian points in space taking into acount the magnet and its certian properties, the bismuths properties, etc...)

| 1810: | Thanks for your help so far, but when calculating
the diamagnetic force created by bismuth, it
would be much easier (at least for me) to use a
formula, or a couple of basic formulas to

variables into TO CALCULATE THE DIAMAGNETIC FORCE
CREATED BY BISMUTH that would be a big help.

| 1824: | Hi! I have a question regarding calculating the diamagnetic force:
You guys said "to calculate the diamagnetic force, use the magnetic susceptibility of bismuth to calculate the induced counter- magnetic field in the bismuth... the magnetization of bismuth will cause it to have a magnetic dipole that is opposite to that of the induced magnet." So, by my understanding you guys are saying that the magnetization of bismuth (which I can calculate by multiplying the magnetic susceptibility of bismuth by the strenght of the applied magnetic field) will cause the induced counter-magnetic field in bismuth? In other words: THE MAGNETIZATION OF BISMUTH WILL CAUSE THE INDUCED COUNTER-MAGNETIC FIELD IN BISMUTH? I CAN CALCULATE THE INDUCED COUNTER-MAGNETIC FIELD IN BISMUTH BY CALCULATING THE MAGNETIZATION OF BISMUTH? THE MAGNETIZATION OF BISMUTH WILL GIVE YOU THE INDUCED COUNTER- MAGNETIC FIELD IN BISMUTH, WHICH WILL GIVE YOU THE DIAMAGNETIC FORCE? Again, you guys said "to calculate the diamagnetic force, use the magnetic susceptibility of bismuth to calculate the induced counter-magnetic field in the bismuth" DO I USE THE FORMULA TO CALCULATE THE MAGNETIZATION OF BISMUTH TO CALCULATE THIS TOO? Again, to calculate the magnetization of bismuth:I can calculate by multiplying the magnetic susceptibility of bismuth by the strenght of the applied magnetic field
|

If I am correct, (correct me if I'm wrong) then lets use the following example of a calculation of the magnetization of bismuth that will cause an induced magnetic dipole that is opposite of the applied field.
(magnetization = magnetic susceptibility * applied magnetic field strenght)
M = (-1.66 * 10^-4) * 1 tesla
M = -0.00166
(correct me if my math is wrong)
- How do I know or calculate the size of the sample of bismuth?
- How do I know when I have enough force to levitate or move the sample of bismuth?
- What am I supposed to measure
"M = -0.00166" in,
What units do I use?
How do I figure out the diamagnetic force (in Newtons) from "M = -0.00166" (to answer question two)

= mu_0 * 0.999834 * H

The dimension would be decently large, the rotating cylinder would probably have a diameter of about 12-15 inches. Any info on some sort of "circular railing" mechanisms would be helpful, even something I could make myself. Thanks for your help.

| 1989: | I am a middle school teacher. Today I did a lesson in which students determined what their weight would be on the other planets in our solar system. We used a formula I found on the internet in another teacher's lesson Plan; the formula is: Mass (weight on earth) x gravity (different for each planet) = weight on that planet.
The gravity chart I used looked like this:
Earth: 1
Our Moon 0.17
Venus .90
Mars 0.38
Mercury 0.38
Jupiter 2.36
Saturn 0.92
Uranus 0.89
Neptune 1.13
Pluto 0.07. My students quickly filled in the chart and discovered how heavy they would be on Jupiter, how light they'd be on our Moon, and Pluto, and Mars and Mercury. Since they finished so quickly I asked them to find their Planetary Average Weight. We decided to throw out the Moon (not a planet) and Pluto (not a real planet anymore.) We found that every single student had an average planetary weight that was within one pound of their weight on Earth! I was in awe of this "co-incidence." I tried more weights, and the result was always the same: 8 planets, total weight on each, divided by eight ALWAYS equals Earth weight. So here are my questions: What makes this true every time?
Is the fact that this is true the reason that Earth is just right for life?
Does our home planet have that magic gravity amount that is exactly the solar system average?
Do the planets acting together add up to the perfect gravity environment for Earth? Or does this formula have other implications?
I am very interested to know your response. Thank you very much.

| 2118: | I understand that after Ozone is broken down from the energy radiating into the atmosphere, O2 and atomic oxygen are produced. The O2 then eventually repairs with another atomic oxygen to form more Ozone. However, the presence of Chlorofluorocarbons apparently destroys the Ozone layer. When I looked at the reaction of the decomposition of Chlorofluorocarbons, I found that it was CF2Cl2 <--> CF2Cl + Cl, the atomic Chlorine pairs with an Ozone molecule, creating ClO3. This breaks down further into CLO and O2. My question is, even if the chlorofluorocarbons are present in the atmosphere, it still provides O2 for more Ozone to be created. So, why is it a problem?

| 2124: | Hi.
What is the pressure at the center of a planet? For example, the pressure at 3 foot depth measured from the earth's surface under rock would be approximately 2.5 pounds per square inch. It is commonly accepted that the gravity at the planet center is zero, equal mass pulling on either side cancels out in the middle. If an object at the center has no weight, then it cannot push on an adjacent object, so there should be no pressure exerted. I believe the pressure distribution curve looks like half a cycle of a sine wave, the part above the horizontal line on the graph, with the depth being the horizontal axis and the left side being the surface, peaking somewhere around 1/2 or 2/3 the radius, dropping to zero at the center. Most accounts claim high pressures and temperatures at the planet center, with the pressure causing the high temperature. I theorize the temperatures are high not because of pressure, but because the planets still have not cooled off after being created. I am not looking for a numerical answer, just an explanation of how the pressure can be anything but zero in a zero gravity field. An assumption I have made is the planet is basically a pile of gravel held together by it's own gravity, not a prestressed structure similar in construction to a prestressed concrete beam, where there would be stress in the middle regardless of gravity. Most accounts claim planets form from the aggregation of material so assume no pre-stressing elements in the construction of a planet. thanks,

| 2131: | Hi! I have a question concerning the properties of centrifugal acceleration and force: Lets say I have a sphere rotating in a circle inside of a spinning cone (it remains the same distance from the center of the cone at all times) Then, lets say you put some thing on that sphere, like a ring (ex. bearings that hold more balls together with a ring) or lets say you simply put a HEAVIER sphere into the cone to rotate alongside the first sphere. Now, my question is: would the heavier sphere rotate at the same distance away from the center as the first sphere (Both spheres are experiencing the same outward ACCELERATION) and would the sphere with the ring still continue to spin at the same distance? In my thinking, I would say yes, because both spheres experience the same acceleration, so they should stay at the same distance away from the center (the outward acceleration and gravity cancel out there - where they are rotating) I would say this because of what we see with gravity: (ex. mass does not matter, ACCELERATION acts the same on any object, but can produce a stronger force. (In the case of the spheres, the heavier sphere produces a larger centrifugal force) Am I right? Please help! Any info will be appreciated! Thanks!

| 2134: | Hi! Thanks for your help on my previous question concerning centrifugal force. I have another question about that: Assuming that one has a cone rotating at some speed on earth's surface, with gravity pointing directy down, would it be possible to have the same spheres that I talked about in my last question support a larger mass? LET ME EXPLAIN: So, you have your cone, and you have a few rotating spheres inside that cone, let's say 4 rotating spheres. Those sphere rotate inside of the cone where gravity and the upward accelerating of the cone cancel out. Now on those spheres is a platform that is allowed to rest on the rotating spheres. The rotating sphere rest inside carved out heim-spheres inside that platform, thus supporting the platform. NOW FOR MY FIRST QUESTION: would the spheres still rotate at the same distance away from the center of the cone? I think yes, because gravity and the upward acceleration of the cone still cancel out. AM I RIGHT? Now let's say a mass is allowed to rest on the rotating platform that is supported by the rotating spheres... Is the entire mass of the spheres, platform, and mass still "cancelled out" due to my thinking in the first question? Now for my last and most important question: What if a non- rotating platform and mass rest upon those rotating spheres, is the entire mass still supported? In ohter words, because the spheres rotate at a point in the cone where gravity is cancelled out due to the cones upward acceleration, the spheres do not have any more measurable weight. But would that still hold true for a non-rotating platform on the rotating spheres, and the mass on the platform? Please let me know. Any info will be accepted, sorry for this super-long question, but THANK YOU SO MUCH FOR YOUR HELP!!!

| 2155: | Hi! Thank you for your help on previous questions. I am still wondering about the phenomenon that is created in straws when one puts his/her finger on the top, and how those properties may be used in different applications. I now know that the diameter of a tube needs to be relatively small to allow the capillary forces/air to keep the liquid inside. Based on that fact, if I were to have, lets say, a solid cylinder, which would be allowed to rotate within a partial enclosure (think of a rectangular-type thing that would go around the cylinder across the middle of the cylinder, across the entire cylinder) The clearance between the cylinder and that enclosure would be very small, as the diameter of a straw is kept small. The clearance, lets say, is 1mm. Now lets say you add some sort of compartment to one side of the enclosure and fill it with water (SO ONE SIDE OF THE CYLENDER IS IN WATER AND THE OTHER IS NOT) Now you put your hand on the open side of the compartment (like you do on the top of a straw to keep the liquid inside) Would the liquid be kept inside, in other words, would the liquid be prevented from flowing thru the 1mm clearance between the cylinder and the enclosure due to the small clearance (much like the small diameter of a straw - to allow the capillary forces to work) and the "vacuum" provided by a person putting their hand on the other end of the compartment? Thanks for your help, it is sort of hard to explain, I wish I could provide an illustration, but I really need your help in figuring out if this application would work. Thanks!

| 2156: | Hi! I have another question relating to the phenomenon that can be demonstrated in straws or small tubes (being able to contain liquids in those tubes by using "vacuum" and capillary forces). Here it is: In this example, lets imagine that a person has a regular straw. But, that straw is stretched outward in the middle to create a larger tube-like "compartment". Basically, the diameter of the straw is small at the ends but is much larger in the middle. Now for the question: Would such a change in the straw's shape or ability to contain more fluid prevent it from holding in that increased amount of fluid thru the use of capillary forces and a "vacuum" provided by putting one's finger on the top end of the straw? In other, simpler words: Would the straw still be able to hold in, lets say, water, if the amount of water was to be increased substantially due to the introduction of the larger, middle diameter, or compartment, of the straw? Furthermore, how could one determine the maximum amount of water weight that it could hold using capillary forces and vacuum alone in a situation like this? How much could the diameter be increased in the middle, how big could the compartment get, while still allowing the weight of the fluid to be supported by the capillary forces and the pressure of the air outside of the straw? Thanks for your help!

Here it is: Lets imagine that you have a length of bendable tubing, and you put some water in it and connect the two ends of the tube, making it circular. Everyone knows that the water that you put into the tube will always go to the bottom part of the circle no matter how you turn your circular tube in the vertical position. But why, when you take a clamp and clamp the tube in one area, you can turn the tube any way you want and the water stays in the same area, even if you turn the tube so that the water is on top. It will not fall to the bottom like it did when you did not have the clamp. I did this experiment and am wondering: Why does the water always fall to the bottom when you do not clamp a part of the circular tube; but when the tube is clamped, the water can be made to stay anywhere? Also, can I replicate the behavior of the water when the tube is clamped, without a clamp somehow? Thanks for your help!

| 2170: | Hi! Hope you guys are having a great day! I have a question involving a recent experiment that I performed: What I wanted to do was to see if I could contain water using capillary forces, etc. in a "hollow, rectangular tube" (imagine a regular straw, but then making it into a square- shaped straw, and then elongating two of the sides of that square that are parrallel to each other to create a rectangular-shaped "straw") Anyway, I wasnt able to make the shape perfect due to the materials that I was using to create the shape. But it did seem to work fairly well, althought water did begin to slowly fall out of the tube when it was in the vertical position due to some air bubbles that I thought might of formed when I was taking the entire tube out of the water. The dimensions of the rectangular part of the tube were 0.5cm by about 1in or so, so I dont think the tube was big enought to prevent the capillary forces from keeping the water in. Do you guys have any idea why the water might be dripping out of the tube? Would you guys suggest making the tube more water/air tight or making a perfect recangular shape to prevent trapping air bubbles? Or maybe making it smaller? Any info will help. Thank you guys so much!

I know that changes in the nucleotide sequences of the same gene have been observed across species, like in the genes that code for polypeptides in cytochrome C and hemoglobin. Based on this evidence a sort of evolutionary time line can be developed to show how far back organisms diverged from a common ancestor by comparing the numbers of differences in nucleotide sequence. In the study of genomes thus far, is there any evidence that suggests a related sequence of nucleotides that result in different functional proteins? Not all organisms have the same proteins, so wouldnt we expect to find that when we find a novel protein on the evolutionary tree, that the nucleotide sequence that codes for that protein would be analogous or similar to a the sequence for a different functional protein? I havent come across anything on this front and was wondering what the experts know. Thanks and I hope you have lots to be thankful for! Sincerely, Bret Klopfenstein Ventura HS

It would be interesting to see, for example, How the impact of a 10-ton object made of a various material, and the destruction that such an object would produce,would compare to the destruction of an atomic bomb. I would assume that 1 atomic bomb would produce the kind of destruction seen in Japan during WW2? Thank you so much for your help, Happy New Year!

-If your answer is no, why can you not consider deep space a vacuum (where there is only about 1 atom per square meter)?; isn't that space between the atoms a vacuum?
-Also, can the space between atoms in the objects around us be considered a perfect vacuum?: ex. a block of steel or wood (or can that neither be proven nor disproven given our knowelege of particles smaller than protons, neutrons and electrons, such as quarks)
-If your answer is no, is another explaination that because if a spcae has no matter in it, then it has a teperature of exactly 0 Kelvin, and if one part of the universe is 0 Kelvin, all of it must be as well (because motion creates heat; and any movement in the universe will be reverberated between atoms) where if the universe was 0 Kelvin, life could not possibly exist. If a perfect vacuum is not humanly attainable, then:
2)How does a particle accelerator work?... given that you are colliding subatomic particles of matter much smaller than atoms themselves(atoms being the matter that cannot be removed from a space to create a perfect vacuum).
-If you cannot remove particles as large as atoms from a space, how can you possibly keep them from effecting the path of a proton traveling close to the speed of light?If it hits anything at all, wouldn't that ruin the test? Thank you for your patience.

| 2258: | Hi! I was wondering: From my understanding of
physics and relativity, a person travelling very
close to the speed of light would see the
universe and history pass at an incredibly fast
rate, and if one were to move as fast as a
photon, time would essentially stop for them
(from our perspective) and they would see the
universe and history pass in an instant. But I
was wondering, If from a photon's point of view
all of time passes in an instant, then what would
a tachyon see from it's perspective? I know
tachyons are theoretical particles that travel
faster than light, but from their perspective,
would they see time pass in reverse or in some
other weird form? Thanks for your help! Any math
or graphs, equations, etc... that may support
this idea that you guys can provide will also be
greatly appreciated.

| 2259: | Hi! When looking at the theories of special and general relativity, it becomes evident that the theoretical possibility of "traveling" into the past using various suitable geometries that may be created is a real one. Also, relativity seems to suggest that traveling faster than light will result to moving backwards in time. Does traveling faster than light result in time travel to the past (according to relativity)? And what mathematical, etc. evidence does relativity provide to support that idea? Furthermore, how would a person be able to calculate the extent to which one would travel into the past (sort of like being able to calculate time dilation between a object moving at speeds just under the speed of light and a non-moving object)? Is there a specific formula or equation that I could use to calculate that? I would assume that in the case of traveling into the past, the "time dilation" would be used in a negative sense, because it is usually meant to calculate how "far" into the future a person would go relative to the earth (in most cases) due to the person's very high speed (close to the speed of light)? I would like to compose a graph of time dilation to the "future" and "past" relative to an object that is moving at speeds close to and beyond the speed of light and a "non-moving" object (time as perceived on earth), if the above ideas suggested by relativity are valid. Of course, that graph would be completely theoretical in its purpose, because an object with mass could never reach or past the speed of light. Nevertheless, I think it would be an interesting way to depict theoretical time travel in a more mathematically and visually understandable way. Thanks for your help!

| 2260: | Hi. In the answer to a question about ethyl alcohol and bacteria you-all wrote that ethyl alcohol can kill bacteria because it denatures the proteins in the cell and dissolves the cell membrane. I am trying to figure out how the ethyl alcohol in handgel affects viruses. I have read that all viruses have a protein coat that protects their genetic material and some have an envelope of fat that surrounds them. If the virus coat/shell is made up of proteins and /or fat if ethyl alcohol denatures the proteins in a bacterium cell, does it also denature the proteins and/or fat that make up the virus coat? If it does this, is this the reason we could say that hand gel is effective in killing viruses that may get on your hand?

| 2267: | Hi! Could the formulas to calculate time dilation in the theory of relativity be modified in a way as to be able to calculate how "far" an object would travel into the past given that the object has a certain velocity that is greater than the speed of light? (In the same way that the current formulas allow one to calculate how "far" an object would go into the "future" given that the object has a velocity that is very near the speed of light) If so, what is the modified formula for time dilation (into the "past") due to an object's velocity (greater than c) and gravitational time dilation (that would allow an object to "move" backward in time)? I would assume that the modified gravitational time dilation formula would pertian to super-high gravities such as those in black holes, which may (theoretically)allow an object that is experiencing those gravitational effects to move backward in time (gravity slows time, maybe a super-high gravitational field would reverse time?)? Thank you so much for your help, your answers are GREATLY appreciated!

Wouldnt this suggest that one could use gravity to send a craft back into time ("exceeds the speed of light from an observers point of view)? Could you explain to me a little bit on the physics of the situation that Ronald Mallett was discussing, and exactly how an object could be considered to be going back in time in the situation that was discussed in the video?

| 2334: | Hello! I have recently been working on a paper that suggests a way of disproving the first postulate of the theory of relativity, as well as the equivalence principle. The mechanism that I am proposing is as follows: Imagine that you are in a large box. You don't know if you are moving at constant velocity or if you are at rest. According to the first postulate of relativity, it is impossible to figure out if you are moving uniformly or if you are at rest. Regardless, you try to build a mechanism of distinguishing between constant motion and rest. You design the following mechanism: Knowing that the speed of light is constant, you shoot a photon from one wall of your box to the other, and measure the time it took the photon to reach the second wall. You calculate how long the trip should take (at rest) and how much longer it should take if your box had some forward velocity. Then you compare your calculations to your observations. You assume it should take longer for light to reach the second wall if your box is moving because the speed of light is a constant and because of some principles of simultaneity of relativity. The theory is, if the box is moving, light (being like an arrow - and its speed independent of the speed of the box) would take longer to hit the target (the second wall) because it moves forward during the time light is travelling to hit it. So light catches up to hit it at a time slightly longer than it would take if the "target" did not move. From that info it becomes easy to distinguish if you are at rest or moving; and at what speed you may be moving. Of course, this is relative to the speed of light, but light speed is a universal constant, so I dont think that poses a problem to the theory. Is the assumption that you make correct? Would this be a way in which one could disprove the first postulate of the theory of relativity, as well as the equivalence principle? Can I excpect to receive a Nobel prize anytime soon?! :-) :-) I'd love to hear your opinion. And if it turns out that I'm correct, I'd be glad to send you a copy of my paper as soon as I complete it, for review. If I'm not correct, then at least I'll understand relativity better. Talk to you soon!

| 2335: | Hi! In my first attempt to disprove the first
postulate of the theory of relativity, I may be
incorrect because distances and time change as an
object moves. Because of this, it may not be
possible for an observer in an inertial frame of
reference to detect if they are at rest or moving
uniformly in this way. But I do have another way
in mind that I would like to ask you guys about,
its based on some principles of simultaneity: If
an observer is in a box (without knowing that it
is moving or at rest) and they have one light
bulb on a wall of the box and another light bulb
on a second wall (facing each other) The observer
turns on both lights at the same time. Wouldnt
the observer be able to detect if they were
moving or at rest due to when they percieve the
light to reach them? If they are moving, light
from one light bulb would reach them first, but
if they were not moving, light from both light
bulbs would reach them at the same time. Is this
true? Could this method be implemented in
disproving einsteins first postulate? Thank you
for your help, I hope to hear from you guys soon!

Of course, the toy does not violate the laws of thermodynamics but I thought it was really cool how one can make a metalic sphere go from "point A" to "point B" by slightly tilting two magnets toward each other. I was wondering, how would it be possible to calculate the momentum of a metal ball that passes thru a SMOT device? For the metal ball to accelerate past the point at which the magnetic fields are the strongest, would the momentum of the metal ball need to be stronger than the strength of the magnetic force? How would I be able to calculate the magnetic force on the ball, to compare it to the momentum of the ball?

| 2373: | Hi! Thank you for your help on my last
question. I recently viewed a concept for a
supposed "perpetual motion" machine. Of course,
according to the laws of thermodynamics, it
shouldnt be able to work. On the other hand,
there doesn't seem to be any flaw in the machine
or any mechanical reason that I can think of that
would prevent it from working. The design goes
like this: There is a pendulum with a metal ball
on the outer end, which swings on the axle of an
electric generator. The pendulum is put in a
vertical position and dropped. It swings about
75% of the way around in a circle as the electric
generator generates a given amount of electricity
. That amount of electricity is fed into another
electric motor/generator with a pendulum of the
same dimensions as the first. Except in this case
the pendulum is at rest pointing down. The amount
of electricity makes the second pendulum swing
50% so that it is in a vertical position, then
the second pendulum drops (as the first one did)
and the process repeats. The result is that both
pendulums continue to rotate indefinitely. It is
supposed to work on the principle that the same
energy that is obtained from a falling object is
the same amount of energy required to raise that
falling object back up to its original position.
But in the case that I stated, each pendulum
swings 75% of the way around, but only need to
raise the second pendelum 50% (allowing the motor
to work with an efficiency of less than 100%) For
example, if the energy generated by the pendulum
going 50% of the way around is 1 Volt, then it
would require 1 Volt to move that pendulum back
up to its original position (but the motor would
have to be 100% efficient) but in this case, the
pendulum swings about 75% of the way around (so
it would produce about 1.5 Volts) that 1.5 Volts
is put into the second pendulum that would only
require 1 Volt (so you can lose .5 Volts due to
inefficiency). Then the second pendulum continues
the process by swinging 75%, and feeding the
electricity generated into the first pendulum
which by now is at rest... etc. What is the flaw
in this concept - or is there really no flaw (in
that case it would work)? I hope I explained it
well enought, but if you guys need clarification,
please look at my diagram in teh link below.
Thank you so much for your help!

Because gravity is simply bent space-time, an object wouldnt nessesarily "move" faster than the speed of light, it would be the bent space-time that is allowing it to attain those (relative) speeds. And because space-time can be bent in such ways as to create superluminal escape velocities (black hole escape velocities, for example)it wouldnt have to obey the conventional speed limit of relativity. Would such a thing be possible?

| 2402: | Hello! Thank you for your answers to my previous question. I have another question involving relativity: Imagine that somehow, one is able to produce a finite acceleration for a given amount of time, or indefinetly (I know that this would require infinite energy but please bear with me). Using this device, the person accelerates an object. Eventually, the object approaches the speed of light. Given my current knowledge, an outside observer seeing that object would notice that it is constantly approaching the speed of light, but (according to the observer) it would take an infinite amount of time for the object to reach, and pass, the speed of light. Is this correct, why is this? However, the object that is accelerating would notice that it would take a finite amount of time (according to it) to pass the speed of light. I know this is similar to the case in which an object is observed passing the event horizon of a black hole. (an outside observer would have to wait an infinity to see the infalling object pass the event horizon, but the infalling object would pass the horizon in a finite amount of time) Now for my second question: Can the accelerating object (or the object that passes the event horizon) still be considered as traveling back in time (when it passes the speed of light according to it, or when it passes the event horizon according to it)? Why or why not? Thank you for your help.
|
|---|
| 2403: | Hello! I have recently tried to calculate the gravity of a black hole at the event horizon. In other words, I want to calculate the surface gravity of an object if the escape velocity to leave that object is the speed of light. But I dont think I did the math right. I believe that the required gravity is less than infinity because there is only infinite gravity at the singularity. How can I determine the gravity of an object when the escape velocity is the speed of light (or more)? Please show how to calculate it. Thank you so much for your help!

| 2406: | Hello! If one applies an acceleration on an object to produce a force (instead of the other way around) doesn't that mean that it would be possible to have an object with mass reach and exceed the speed of light? To reach this conclusion, I rearranged a variation of the formula f=dp/dt (from special relativity) to solve for a given acceleration. I found that as an objects mass increases (as it approaches the speed of light) the force provided by the constant acceleration should also increase proportionally to maintain that acceleration. At the speed of light, the applied acceleration would impose an infinite force on the object with infinite mass to maintain the acceleration. In my thinking (which is theoretical) If one was to use an acceleration to create a force to apply on an object instead of using a force to create an acceleration on the object then what I just stated above should be possible. Is my thinking correct? I also think that an outside observer would still percieve the accelerating object as requiring a nearly infinite amount of time to reach the speed of light (while according to the accelerating object it requires a finite amount of time to reach the speed of light and surpass it) due to the time dilation effects that also occur at those speeds. Is my thinking correct? Thank you for your help!
|
|---|
| 2407: | Hello! I am also wondering, if one was to apply an acceleration that is above the value of "c" on an object to create a force on that object then in that case, wouldn't outside observers as well as the accelerating object agree that it would only take a finite amount of time to reach and surpass the speed of light?

| 2409: | Can time dilation be transfered between entangled particles? In other words, if one has two particles that are entangled (based on quantum non-locality) and one particle is placed in a deep gravity well while the other is in deep space, will the particle that experiences time dilation (in the gravity well) relative to an outside observer "transfer" its time dilation to the second particle that is in deep space? So that BOTH of the particle's clocks run "slow"? If so, why? If not, why not? Thank you so much for your help!

| 2411: | Hi! Thank you for your answers to my previous questions. I recently viewed an episode of the show "Through the wormhole" that dealt with black holes. I think it was called "The riddle of black holes". Anyway, toward the end of the show the apparent similarities between the behavior of black holes and atoms was discussed. If such similarities really exist, wouldn't it be possible to somehow tie the theory of relativity and quantum mechanics together by using that phenomenon?
|
|---|
| 2412: | Hi! I have another variation of the time dilation question that has to do with entangled particles: Suppose you have a pair of entangled particles. You put one in a particle accelerator and get it moving at a speed just under the speed of light. However, you take the other entangled particle and set it aside for observation. According to special relativity, the particle in the accelerator should experiences some time dilation due to its very high speed (close to c), and because both of your particles are entangled, the particle you set aside for observation may also experience time dilation (to maintain some sort of symmetry or whatever). So the question is, will you observe the time of the particle you set aside to look at as mysteriously running slower relative to its surroundings (as the clock does on the moving particle)? I understand that you said before that the physics just arent there to make these kinds of predictions (between relativity and QM) but if you were to make an educated guess, would you guess that both entangled particles experience time dilation because of the fact that they are entangled or not? Thank you for your help and opinion! P.S. Just a thought: couldn't such an experiment actually be performed? To my knowledge there are some pretty powerful particle accelerators around the world... if they were to perform this experiment maybe they would be able to finally discover the ties between relativity and QM! Just remember... it was my idea, hahaha. Have a great day!

| 2413: | Hi! Based on the principles of quantum non- locality, I know that it is possible to entangle various particles.

| 2418: | Hello, Im in 6th grade and I just finished reading Michael Crichtons book Timeline. In this book one of the characters states how time does not exist. He states The very concept of time travel makes no sense, since time doesnt flow. The fact that we think time passes is just an accident of our nervous systems-of the way things look to us. In reality, time doesnt pass; we pass. Time itself is invariant. It just is. I was wondering if this was true or not. If it is true wouldnt that make time not a dimension, or not a part of the continuum, and wouldnt that negate relativity. Please respond if you can.

| 2456: | Hello- We are doing an osmosis lab involving a
decalcified egg in water, salt water and corn
syrup to show how concentration affects the
movement of water across a membrane. The egg
shrinks in salt water and corn syrup and swells
in fresh water due to osmosis- pretty
straightforward stuff. One of the students asked
what would happen if we put the egg in oil as
opposed to the other solutions being tested-
great idea, so we hypothesized and tested. We
supposed that since oil has no water in it, it
represents an area of higher concentration, and
therefore the water should move out of the egg

| 2458: | Hello! I was wondering about the following experiment: lets say that you have a laser, and that (single) laser is positioned parallel to one side of a triangle, and perpendicular to the second side, with the hypotenuse being 45 degrees to the left (or right - it doesnt matter) of where the laser would shoot a single photon. This is how the experiment goes: you turn on your laser and it shoots a single particle, moving at the speed of light (which you measure). But, you also record (using another camera or whatever) the reflection of the particle across the hypotenuse. (Or maybe this could be done in a dark room and you just measure the speed of the laser beam/photon across it visually. Another way you could do it is if you measure the speed by having two points on the hypotenuse that measure when light passes across them, and you could measure the time it would take for the reflection to go between those points... that way if you know the distance between them you can calculate the speed of the reflection) Because the hypotenuse is longer than the distance that the particle moved (and was traversed in the same amount of time) the reflection should be measured as moving faster than light, or "back in time". From what I have been able to figure out I dont think you'll have to deal with time dilation effects or anything fancy like that, so: Would this be the case?! Please explain why or why not. Thank you so much for your help!! Have a great day!

| 2466: | Hi! Thanks for answering my previous questions. Considering the fact that a particle moving at (.999)c could be seen as moving at a speed greater than c if observed on the hypotenuse (but contains no information), could not you create a situation where that particle does contain information? This is sort of based on the tachyon antitelephone example: Let's assume that you have one person at the ends of the hypotenuse, person one sends a signal at c (or vc along the hypotenuse, the reply could cover "more" distance in "less" time and appear to go against causality. Is this true? Would such a set-up go against causality (to one extent or the other)? Sorry for the long question, but thank you so much for your help!!

| 2474: | In a voltaic pile with copper and zinc as the two metals and with aqueous sodium chloride (salt water) as the electrolyte, what happens to the electrons and ions and what reactions occur? I understand that in a copper/zinc voltaic pile using sulfuric acid as the electrolyte, the zinc electrode decomposes into positive zinc ions (which dissolve into the electrolyte) and 2 electrons, which travel through the exterior wire to the copper electrode. At the copper electrode, the electrons are then accepted by positive hydrogen ions from the electrolyte solution which form hydrogen gas at the copper electrode. The problem I see when this is adapted to a sodium chloride electrolyte is that the positive deposited ion would be pure sodium and it seems unlikely that sodium would form in its pure form both because zinc cannot reduce sodium (being lower in the reduction potential list) and because sodium is very hard to obtain in its pure form. Nonetheless, using a sodium chloride electrolyte for a voltaic pile seems to work frequently in many household experiments (according to my research), So my question is: What is going on? Is there a new, different reaction? What happens to the ions and electrons?

| 2480: | After reading some stuff on ferrofluids, my son hypothesized that stronger magnets next to ferrofluids would create smaller spikes than weaker magnets. It turned out it was not true, although the differences were minimal and there were also several problems with taking the measurements. But whatever the right hypothesis is, what makes the difference? Here is the passage we took from somewhere on the web that is confusing to me. Before I paste it below, let me say that it raises my question 2: the relationship between magnetic field, magnetic force, and magnets. I know this is too big a question and might be answered with a simple explanation for question 1 (if there is a simple explanation...). "The stronger the field, the smaller the spikes. In the weedy field from a ferrite magnet you'll get just a smooth mound of fluid with a few spikes where the field is strongest, but the spikes get a lot smaller when you're playing with one of the bigger neodymium magnets."
Thanks so much!

| 2482: | Hello! Recently I viewed an article on wired.com titled "A User's Guide to Time Travel," of course I can't say that it was very helpful in demonstrating practical time travel, (these kinds of articles never do that, lol) the ideas that it proposed were interesting (I thought the pictures were nice, too). Anyway, on the second page of the article the author talked about a "Gott Shell". Now from what I understand, it would work by producing a time dilation effect because of the incredible mass of the Shell, "propelling" the traveler into the future. In essence the greater the mass, which produces a greater escape velocity, creates a large time dilation effect. (relative to someone outside the sphere, of course) The author mentioned how it could only work in one direction - toward the future. But, after thinking about it, I wondered: What if you got so much mass together that the escape velocity of your Gott Shell exceeded the speed of light (sort of like a black hole, but thats beside the point)? Wouldnt you, due to the fact that youre in the center of the shell, ("experiencing" the time dilation effects) now "move" back in time? Keep in mind that this is purely a thought experiment, and would most likely never be possible in reality. Why or why not? Thanks for your help!!

| 2484: | I have a simple question regarding basic thought experiments to do with special relativity (which we just started in school). The thought experiment our class went through to explain time dilation was of a train travelling at relativistic speeds with a pulse of light moving up and down in a straight line within the train (reflecting off a mirror on the roof). Relative to an outside stationary observer, the light pulse is moving over a greater distance than just up and down (it is travelling the hypotenuse of a right angled triangle because of the train's motion on the x-direction), but because light travels at 'c' in every reference frame, the pulse must still travel at the same speed 'c' relative to the outside observer. Hence, because it travels a greater distance with the same speed, it must take longer to do so and hence time will appear to be running slower within the train - relative to the man outside. I understand the logic behind this however it seems to me that the thought experiment could be turned on its head by changing the direction the pulse is fired at. Say for example that instead of straight up and down, the light pulse is shot in a direction opposite to that of the trains motion, with an x-component equal to the motion of the train (i.e. if the train is travelling right at 0.5 'c', then the light pulse is fired left with an x-component of 0.5 'c'). If this were the case, the stationary man outside would now see the pulse travelling straight up and down relative to him and therefore see the pulse travelling a smaller distance. because the pulse still travels at 'c' relative to the outside observer he will now see the pulse travelling a smaller distance with the same speed, i.e. in a quicker time. To the outside observer, time now looks as if it has sped up inside the train (but of course this must be wrong because 'time dilation' says that time will always slow down for a stationary observer looking into a fast moving reference frame) I am wondering what exactly is wrong with this thought experiment. it uses the same logic as the original thought experiment (which was taught in my syllabus) but achieves the opposite result, it seems to prove time 'contraction' rather than time dilation. Help would be greatly appreciated.

| 2489: | Thank you so much for your answers. School is going great! I will also discuss this with my professors. But just to clear up some confusion that I had, I always believed that time "stopped" on the event horizon (not the singularity), and the singularity was just, as you said, a point of zero dimensions, infinite gravity, density, etc. (Most people think that this is just where relativity and physics in general breaks down, but I don't know enough to talk about that) I have always compared the event horizon to the speed of light, in other words, if you take into account what an outside observer would see if a person fell into a black hole it would be similar to what they would see if a person began approaching the speed of light. If you look at someone who is continually accelerating and approaching c, you would see them get closer and closer to the speed of light but never actually get there (from your point of view), you would also observe their clocks running differently than yours. Now if you look at someone falling into a black hole, you would see much of the same thing: the person who is falling in continually approaches the event horizon, but never actually gets there (from your point of view) you also, like the speed of light example, see their clock run slower than yours. So I have always thought of the event horizon like reaching the speed of light - if you reach the speed of light time "stops" for you relative to the outside observer, and if you reach the event horizon time "stops" for you relative to an outside observer. But what is nice about a black hole is that the person falling in can actually pass the event horizon (never mind the fact that he or she can never get out - this is purely a thought experiment so we do not have to worry about that). Eventually you reach the singularity, but I don't think we can really describe that point in the detail we want with the physics we have. So what happens between the event horizon and the singularity? Where gravity is strong enough to prevent light from escaping but does not yet equal infinity? This is where I might have gone wrong, but I have always thought of this as "exceeding" the speed of light (because you have past the event horizon, which was like the speed of light). Now we all know that for the person falling in, time would pass at a perfectly "normal" rate, but how would he or she see time in the rest of the universe pass (If they even could see the rest of the universe at this point)? Or how would you see their time pass if you could look into the black hole? Would being in a gravitational field that has an escape velocity greater than c but lower than infinity be equal to a velocity greater than c (or would it have the same effects as a velocity greater than c but less than infinity - because we really cant describe infinity)? The whole point of these questions is to try andm understand if time "travel" to the past is even a remote theoretical possibility using this method. Thank you again for your help, it is greatly appreciated!

quantum entanglement. I know that, theoretically,
if one was to take two ends of a wormhole and
keep one stationary while one moves around, it
would be possible to travel back in time. Could
this be duplicated practically by using entangled
particles - due to the fact that they are
connected instantly much like the two ends of a
wormhole? In this experiment, one would keep one
particle stationary while moving the other one in
a particle accelerator or something like that, to
observe the time dilation effects between them
(hopefully resulting in some form of backwards
time travel effects, like the case with the
wormholes). What is your opinion on this? And is
it right to compare wormholes to entangled
particles because of their similar
characteristics (with regard to connecting
different points in space - or different
particles separated by space) instantly? Thank

| 2557: | Hello, I was looking online about the Nernst equation, and someone was talking about the idea that if the value of the reaction quotient ends up being 1, the temperature of the system will have no effect on the cell potential. With the equation, the log of 1 is zero, so I can see where they got that from. However, I would think under Le Chatelier's principle, a change in temperature would still affect the voltage. Now using the relationship between Gibbs free energy (∆G) and ∆G under standard condition- ∆G=∆G(Standard condition)+RT*Ln Q- It appears that when Q=1, the temperature has no effect. Why would this hold true and how would that pertain to the value of the cell potential at different temperatures?

| 2591: | Hello, Recently I was also shown the classic free
energy example of a steel ball rolling up a ramp
with a magnet on top, only for the steel ball to
fall back to its original place... with the
process restarting. Of course, this could never
work, but I was wondering, what if one was to put
a thick copper tube along the ramp, and replace
the steel ball with a magnetic ball. By doing
this, the eddy currents produced by the steel
ball in the copper tube as it is attracted to the
top will slow it down. If one makes a hole in the
ramp, the slow speed of the magnetic ball should
allow it to easily fall through, to its original
place. Would the addition of the copper tube
(with some tinkering) allow such a device to
work? Thank you for your help!! Best,

| 2597: | Hello,
I know that time "stops" at the speed of light, but at what gravity does time "stop"...?? To clarify: From my knowledge of special relativity, if an outside observer were to watch someone move at the speed of light (which is impossible, but bear with me for the example's sake), the time for the person moving at the speed of light would "stop" (from the outside observer's point of view). Knowing this, I wonder if this is also somehow applicable in general relativity (in my opinion, there should be some sort of equivalence between the effects of moving at the speed of light (in our example) and a large enough gravitational field. I also think that, because the speed of light is finite, so should the gravitational strength required to "stop" time using gravity be finite). So my question is: how strong does a gravitational field have to be to "stop" time for an object experiencing the gravity (from the perspective of an outside observer, of course)?? Please show the math behind the answer, if possible. Thank you!!
|
|---|
| 2598: | Can you guys take a look at the formulas given

gravitational field would have to be to stop and

valid. Thank you so much for your help! Best

| 2600: | I am doing great, thank you for asking! I also want to thank Anthony and Andy for answering my question! I have tried to calculate the Schwarzschild radius before, but I had some trouble doing it. From what I was doing, I wanted to calculate the gravity of a black hole at the event horizon (I'm also assuming that the gravity of all black holes at their event horizons has the same value) with the assumption that that gravitational strength would be enough to stop time (from an outsider's perspective). I assumed that time would "stop" at the event horizon because, as an object approaches the event horizon, an outside observer perceives it in similar ways to if the object was approaching the speed of light (ex. time slows for the object to almost stopping nearing the horizon, its acceleration "slows", it never actually crosses the horizon... all factors that would also be attributed to that object if it was approaching the speed of light). Anyway, I'm having trouble with the idea that an outside observer would only see time for the object stop at the singularity (at infinite gravity), when in fact time slows to almost stopping as it gets closer and closer to the event horizon, where gravity is still finite (that's why I assumed it "stops" at the horizon from the perspective of an outside observer). As I was doing some more research, I came upon some information that would describe how far an object would move back in time if it was moving faster than light (using special relativity). I was wondering if I could use the same idea and apply the information to general relativity (using the formulas for general relativity, of course), in order to mathematically calculate the required gravitational strength to stop/reverse time (just like the info in the attachment calculated the required speed to reverse time). On what I read, the author uses the Lorentz transformation to calculate how far back in time an object would go if it moved at a speed greater than the speed of light (from the perspective of an outside observer). Is there a counterpart of the Lorentz transformation in general relativity that I could use in order to calculate the gravity needed to stop/reverse time? If not, what could I use to do such a calculation? Once again, I would just like to thank you guys for all your help regarding this subject. I only have a limited (but growing!) knowledge of relativity, and your answers have been very important in helping me gain a deeper understanding of how this theory works. Thank you! Best Regards,
|

| 2601: | After playing around with the formula for gravitational time dilation, I have noticed that, as the gravitational potential equals (- c2/2) time "stops". If you go beyond that time becomes imaginary. Of course, using this formula I'm not able to calculate how far "back" in time an outside observer will perceive someone going if they encounter a gravitational potential of this value (the formula wont let me calculate that). However, I know that, in general relativity, the gravitational potential is replaced by the metric tensor. I assume that if I was to implement the metric tensor I would be able to calculate how far "back" in time someone will travel (from the perspective of an outside observer) in the same way that the author of Space-time physics was able to calculate how far back in time an object will travel if it moves faster than light (from the perspective of an outside observer). I have included another copy of that information in the attachment. What metric tensor do I use to perform the coordinate calculations in order to calculate how far "back" in time an object would go (from the perspective of an outside observer)? How do I perform those calculations? Thank you for the help!

For example, a student who is weak in mathematics and wish to improve on it should say the self- affirmations as I am excellent at mathematics & also visualize himself as ALREADY being good at Math repeatedly. Or a person who is a coward could reprogram his mind by saying to himself, I am brave, etc. This is so that the subconscious mind is set with the positive intended goal and thus will program the whole body with the message. But the question is that such self-affirmation is not the truth (or not the truth yet). When he is telling himself that he is ALREADY being good at Math, he is actually lying to himself. So, would it better to say,I am getting better and better at Math rather than I am excellent at Math?

thought I would do an experiment to test 3
antacids to see if one worked faster than the
other. For my science fair project on
heartburn relief, I plan to - test 3 antacids
using the red cabbage juice as an indecator
adding vinegar to make the solution represent
stomach acid. I plan to test Mylanta, Rolaids,

will neutralize the acid the fastest. I want to
use a stop watch and graph the results.
I'm in need of advice. Please answer a few
questions.
Do you think this is a good
experiment to do?
What else do I need for
this experiment?
Should I test more than
three?
What should I put in the report?
I want to do this project next weekend and

| 2924: | A teacher at this school did a science experiment
where he had two balls of different masses go
down an incline which was raised about 20cm above
the table. The balls were released from the
same point on the incline and he assumes they
accelerated at the same rate and so when they
left the incline they were going at the same
speed (I'm not sure this is true). In any case,
the ball with the larger mass hit the table at a
farther distance than the ball with the smaller
mass. Could this be true if they were going at
the same speed when they left the incline? It
seems to me that they should hit at the same
place. I don't think the friction of the air
would cause enough resistance to cause any
difference. The larger ball would have more
momentum but this shouldn't affect the rate at
which a ball falls. Am I missing something or
what accounts for the different distances the
balls go through the air?

| 2987: | We've been studying the planets in my science
class. I read this article in the Time magazine
(March 1998), that there might be water on one of
Jupiter's moons, Europa. I think that the title
of the article is misleading "Aliens in a Slushy
Sea". They say ice that they found may mean some
liquid under the ice layer. My reading of the
article tells me that they are trying to make us
think that there may be water on this moon. I
find that hard to believe! Couldn't the ice that
they found be frozen Carbon dioxide and not
water? Do you have any more info. on the subject?

body and fender work on cars that "car cancer"
(rust) has to be completely removed and in the
really bad places cut out and a new piece of
metal welded in or the rust would just continue
to destroy a car. I thought that rust was the
result of iron and oxygen reacting creating iron
oxide! If I cover up the rust with paint or
"bondo" (sp?), and air can't get to it (no oxygen
so no reaction), why would it continue to get worse?

helicopters and trucks spraying the fields with
pesticides. Our track at school is less than 20
feet away from those fields. We run a mile for

| 3042: | This week we have learned about alpha, beta, and
gamma nuclear radiation and decay. We know that
in beta decay a neutron is lost and a proton is
gained, and that the daughter element has one
more proton than its parent. For example, when
Thorium-234 beta decays into Protactinium-234.
This has aroused two questions: If the number of
electrons is the same as that of the protons in
normal atoms, does the new Pa-234 get a new
electron in the electron cloud, and if so, where
does it come from? Also what happens to the
electrons that are left over when radioactive
elements like Uranium-238 alpha decay? Does
alpha decay somehow include a loss of 2 electrons
so that the daughter element is not an ion?

| 3165: | In regards to extraterrestrial life, I wonder
about their "rate of life". I mean, could what
we call a second be a year for their species.
So, a message from us like "Hello" would be a
year- long
"HHHHHHHHHH...eeeeeeeeee...lllllllllllllllll
lll...oooooooooo." If our thought processes are
at two very different rates, then communication
would seem impossible. OR, is there one rate of
life in all the universe? It seems that this
would have to be the case for any contact to
occur since the probability of another species'
"rate of life" being close to ours appears to be
zero. Do you think our rate of life is connected
to the speed of light. So, for example, an alien
species with a rate of life one hundred times
ours would see light travelling one hundred times
slower? (or faster?)

problem, but overall I think the calculations
should still approximate a real life situation.
I would like to make sure that we have not made
any errors, however. Would you guys mind looking
at it and making sure our calculations are
correct?
Thank you!
∑ FY = (– m*g) – N2M + (N*sinθ)
= 0
∑ FX = (N*cosθ) = m*(v2/r)
N2 = (m*g) – (N*sinθ)
(N*cosθ) = (m*v2)/r
N = (m*v2)/(r*cosθ)
N2 = (m*g) – ( ((m*v2)/
(r*cosθ))*sinθ )
N2 = (m*g) – ( ((m*v2)/r)
*tanθ)
N2 = m*(g – ((v2/r)
*tanθ) )
“Up” Force = N2 = m*(g –
((v2/r)*tanθ) )
Where v equals the tangential velocity of the
rotating cone.

| 3403: | I have a question about the genetic
similarities between the major primate species
(orangutans, chimpanzees, gorillas, gibbons, and
bonobos) and humans. A lot of times one hears
about how humans and chimps are the closest to
each other genetically, differing in their
genetic makeup by only a few percent. I´m
wondering though, how close genetically are the
great apes to each other?
For example, how close are chimps to
gorillas, gibbons, or bonobos? Or gorillas to
orangutans, etc.? Do you guys know of any
references comparing the genetic codes of all of
the great apes to humans (from which I could
deduce how similar the great apes are from
themselves)? Or perhaps a direct comparison of
primate genetic codes to each other? I´m mostly
interested in the overall percentage difference
between each species, but I´d love to look at
any additional information as well such as where
their genetic codes differ with regard to each
other.
Any help or references to resources on the
subject would be greatly appreciated! Thanks!

| 3408: | For my 8th grade science project, I have
decided to conduct an experiment to see how the
temperature of air affects the speed of sound in
that medium. I have made some research on the
subject, and I have found a design for an
experiment to do this test:
I have to insert on one side of a plastic
cylinder a speaker, delivering a pulse at a
regular rhythm. On the other end will be a
microphone connected to an oscilloscope, which
will be mounted so that I can adjust its
position from the pulse. By moving the
microphone enough to change the position of the
graph on the oscilloscope, I can find the
relationship between the distance of the pulse
and the microphone in relation to the increased
time. By doing this several times with various
distances I can estimate the speed of sound, and
by heating or cooling the air in the tube (using
applying ice packs on the sides, or heating it
with a blow dryer) and measuring the speed of
sound at those temperatures, I will be able to
see the relationship between the speed of sound
in air and the temperature.
Could any of you help me to do this
experiment at your lab, where we will need a
pulse generator and an oscilloscope? I will
take care of the rest of the equipment that I
need. I think that this experiment will take a
couple of hours and I will do my best while
working there.

| 3475: | Hello, my name is Jenna. I am an 8th grade
student at La Colina J.H. I am currently working
on my science fair project. My Science fair
question is:
How does a wetsuit affect drag?
My procedures are:
1.Wear a competition swimsuit.
2. Swim in 25m pool
3. Swim 100m.
4. Measure and document time of 100m swim.
5. Rest 2 minutes.
6. Repeat steps 1-5 nine times.
7. Average the times of all 100m swim sets.
8. After a week of rest, wear a triathlon
swimming wetsuit of 3mm thickness neoprene with
no
arms.
9. Repeat steps 2-7 wearing wetsuit.
My hypothesis is: If the wetsuit does create
drag
then I think the competitive swimsuit will
provide
better speed and time then the wetsuit.
IF you have the time I would really appreciate
answers to these questions.
a. Do my procedures sound like they would
work for
my experiment?
b. Is there anything I could do to make my
experiment better?
c. Would it be better to do five trials of
the
competition suit and then five trials of the
wetsuit on one day then do the same thing a week
later?
d. Is there any vital information about
drag I
should know before conducting my experiment?
e. What is the best way to measure drag?

| 3476: | Hi scientists,
I am in 8th grade and I\'m starting to work on
the
science fair project. The question for my
project is:
How does sight affects taste?
I will test that by having 3 equal amounts of
soda
drinks in clear cups. One will be cherry, one
will
be grape and one will be lemon/lime. The
volunteers will first taste each drink and try to
guess the flavors. Next, I will blindfold the
volunteers and have them guess again. Then I will
add food coloring to the drinks to make the
cherry
look like grape, lemon/lime look like orange and
grape look like root beer or cocoa cola. The
volunteers will then test each drink and tell me
what they think each flavor is. My hypothesis is
that on the control and blindfolded test, most
people will guess correctly. On the incorrect
colored test, I think people will guess the
cherry
to be grape, the lemon/lime to be orange and the
grape to be coca cola.
a. Do you think that the procedures should
be done
differently in order to answer my question (How
does sight affects taste)?
b. Do you think the colors of each flavor
make a
difference, or should I change them?
c. Do you think my hypothesis is correct?
d. Is there anything important that I need
to know
before I start conducting the experiment?
e. How many volunteers do you think I
should have
to make the experiment reliable?
f. How do you think I should graph this
information?
g. Do you think this are too many variables
to
deal with, and should I make it to just one
flavored drink?
h. Is there anything else you know about
why sight
effects taste that you think is important to
conduct this experiment?
i. What do for your career, and what is your
knowledge in this topic?
Thank you so much for your time and expertise on
this subject. This will help me greatly on my
science project.

experimenting plant gravitropism, by growing
three
bean plants upside down, and three right side up.
I have some questions for you to please
answer:
1. For the upside down bean plants, I just put
the
seed in normally, however it still grew upwards.
The roots came out of the bottom of the fiber
seed
starter pots, and the shoots burst through the
pot
and grew upwards! I expected the plant grow down,
and then curve up.
2. What would have happened if the pot was clay?
Would the shoot have turned around when it
reached
the top, and grow out the bottom?
3. What should I have done if I do the experiment
again?
4. I know about negative and positive geotropism,
and I now feel bad for having expected it to grow
down and then up!
Thanks so much!- Natasha

found
that the part of the brain that receives these

brain is the Hypothalamus and how large is it in
comparative size to the rest of the brain.?
What is the rate of temperature increase or
decrease to room temperature for water that I
should use in my experiment?
When using statistical analysis, what is the
most effective way to have realistic numbers?
I plan on using set ranges of temperatures for
people to estimate the temperatures for. I am
going to tell them what these ranges are; just
that they are hot, room temperature, and cold. I
plan on having the cold at around 30-40 degrees,
the room temperature from 60-75, and the hot at
100-110. Do you think this is a good idea or
should I just have a set temperature for each
section of the test?

click
hear to read
In this case we have the same closed, rotating
hollow cone whose rotation at some tangential
velocity w is perpendicular to the direction of
gravity (so the tip of the cone is pointing down,
and the cone rotates on a horizontal plane). The
incline of the cone is 45 degrees, but I suppose
it can be any angle x. The cone has a radius r.
Instead of containing several spheres, like my
last question, this cone contains some fluid of
known volume, density, and mass. As the cone
begins to rotate, the fluid co-rotates with it,
climbs up the incline and presses up against the
top lid. Eventually the cone's tangential velocity
is stabilized and the fluid exerts a constant
force on the inside of the cone.
Knowing this information, how does the physics
in calculating the x and y force components of the
force that the fluid exerts on the inside of the
cone change from the case of the rotating spheres?
How can one calculate the x and y force components
of the force that the fluid exerts on the incline
and lid of the cone, respectively?
Thank you for your help!

School. I have been reading online about Wi Fi
radiation (EMF or high radio frequency) and the
health risk in children. I am concern about it
and heard that in France they are pursuing "wired"
technology in their schools. Our school plans to
implement iPads (wireless) next year for each
child as part on the 21st Century Technology
Initiative. Do you have or know of any research
that can help me understand this further? What
are the risks since the technology is fairly new?
I know that the FTC's guidelines are outdated
since their standards are based on the 1950's or
something a long time ago. I have looked at EMF
portal's website and found things but I think we
need someone (ie. Physicist or person who works in
the field) who is more knowledgeable to put things
in perspective. I think of UV radiation and
smoking when I think of WiFi radiation. I would
not like to find out years later of the harmful
effect. I would
rather have it tested out to be safe then use it,
if possible. There will be many children affected
by this. Please help us understand better.Thank

| 3926: | Let's say you have a magnet levitating off a
metallic surface. Classically, there is no work
done so there is no change in the energy state of
the magnet. We can expect the magnet to float
forever. Quantum mechanically, the electrical
repulsion is produced by the exchange of virtual
photons. A naive picture of this imagines the
virtual photons to be like bullets: the magnet
stays aloft by shooting these photons like bullets
off the surface. We can't expect the magnet to
have an infinite supply of bullets. However,
unless somehow the magnet never runs out of
bullets,(which makes you wonder about energy
conservation), the magnet would eventually settle
to the ground. So, what is the correct take on
this situation? Thank you.

posted topic:"Why is tungsten used for filaments
in light bulbs when nichrome's resistivity is so
much higher?
"http://scienceline.ucsb.edu/getkey.php?key=2548
I understood, after reading your answers, the
importance of the high melting point of the
material of the filament. In order to get visible
electromagnetic waves (i.e. light), we need the
material to be at a certain temperature and it is
tungsten that can reach that temperature without
melting. However I do\'t understand another thing.
The power supply is given by a constant VOLTAGE
supply, say 120 V (not constant current). Ohm's
Law states V=I*R And Joule's effect states
Q=I2R By combining these two
equations, we get that Q=V2/R. Then,
why we would want to have a material with a high
resistivity? If V is fixed, then Q actually
DECREASES with the higher R. The former equation,
I2.R, might be confusing but the thing is
that, as said before, I is not fixed, but V is.
So by increasing R, we are decreasing I and
that's why I2.R will decrease. In
conclusion, I understand that tungsten is a good
material because of many of its properties, as the
high melting point. But, why to increase the
resistance of the filament by increasing its
length and decreasing its cross-section since it
seems to me that it should be the other way round?
Were am I making the mistake? Sincerely

| 3999: | I have found myself stuck trying to understand
parts of AC generation so I am writing to you to
ask if you or anyone you know could possible
answer my question.I am finding it hard to
understand each magnet poles magnetic effect of
the electrons in the coil, how do the electrons
decide which way to go inside the coil? So as a
guess I would say :- in an alternator before the
coil even spins, the magnets lines of force
polarizes the two ends of the coil, leaving one
end of the coil positively charged and the other
negatively charged, then as the coil is spun 180
degrees, the electrons rush to the other side of
the coil which switches the polarity.
Does voltage exist between the two terminals?
That potential difference in the generator is
between the
two sides of the coil, but how is this
established? My understanding of potential
difference tells me that for there to be a
difference in potential there has to be un-even
amount of electrons between two points, where one
point possesses too many, and the other possessing
too little, thus there is a potential difference
between the two, in which the electrons will
desire to travel from the higher potential to the
lower potential point.
I'd really appreciate if you could clear this
up for me in the most basic language possible.
Thanks so much in advance.

| 4147: | Dear UCSB Researchers, I am an 8th grade
student hoping to research methods of resisting
bordetella pertussis disease. I was thinking that
if there was a vaccine that would increase the
growth of cilia on our ciliated epithelial cells
in our respiratory system, then we would be more
protected from whooping cough. Would you think
this could be a good hypothesis? "If our
epithelial cells in our respiratory system produce
continuous amounts of cilia, then our bodies will
be more protected from bordetella pertussis." I
see two possible questions to study:
1. Is there a chemical that can grow more cilia
on lung cells?
Or
2. What can I use as a safe substitute that is
just like bordetella pertussis?
I think that pertussis is too dangerous to use
as a bacterium, so what would you recommend as a
substitute? Also, how could I grow these cells at
my home without a lab? Is there a way I can grow
more cilia on cells? How could I actually measure
how many cilia are present (would I take a picture
and count)? Thank you! From an 8th grade
scientist.

the author hinges around the idea that a virus is
genetically programmed to attack cells. We
already know that. What is missing is how this
viral genetic code was written in the first place.
This is not a philosophical question!
The point is as follows: evolution is an
ongoing biological process and different life
forms are different form one another. Having said
that, it is not clear how the genetic make-up of a
virus can be designed in order to successfully
attack cells. Consider the differences between a
bacteriophage and the Human Immunodeficiency Virus
(HIV). Clearly, they have different structural
properties that allow them to successfully invade
the corresponding targets. Why? How did it
happen? What are the fundamental mechanisms
underlying viruses, i.e., design and build a virus
that will be able to infect the following cell?

station. The station is rotating about its axis at
some rate R clockwise as seen from the perspective
of an outside observer (or an observer at the
axis). On the station there are two astronauts.
One is standing in place and rotating clockwise at
the same rate R as the station from the
perspective of the outside observer. He
experiences some centrifugal force F away from the
axis of rotation. The second astronaut, doing some
exercise, is running counter-clockwise, at the
same rate the station is rotating in the clockwise
direction (lets call his rate -R). As seen from
the perspective of the outside observer, it seems
like the astronaut is jogging in place. Question:
Does the second astronaut, rotating at the same
rate as the space station but in the opposite
direction, still experience the centrifugal force
caused by the rotation of the space station?

hypothesized that Classical music would lower the

hypothesized that Rap, or any high-temped music,
raises norepinephrine levels.
My studies have shown that this is true, but
not in every case. 50% of my subjects’ blood
pressure rose while listening to rap, but the
other half did not, instead staying neutral e or
even lowering. 75% of the subjects’ blood pressure
decreased with Classical music, but the effects
were not as drastic. 50% of the subjects enjoyed
rap, which is probably the cause of the lowered
blood pressure. 50% enjoyed classical music, or
knew the song, which is why their blood pressure
lowered. The heart rates of all the subjects made
no pattern during this experiment, except after
the classical music was played. In conclusion to
my experiment, I realized that whichever genre of
music you enjoy lowers the blood pressure, not due
to the rhythm.
Can you relate to my conclusion? Do you think it
is accurate? Thank you so much!

sorry to bother you, I am contacting you after

I was hoping that you would able to answer a

thinking about doing for the BT young scientist.
1) Do different spectra of light effect the
growth of plants differently? (Ignoring green)
2) Do specific combinations of light i.e. red,
yellow and blue of an equal intensity to solar
light effect plants' growth?
3)Does the effectiveness of the light on
photosynthesis vary throughout the day? If so do
different spectra affect this?
The above questions are to aid in setting a
baseline for experiments, as I haven't been able
to find any definitive proof online.

| 4394: | After reading your article:"Why is it that
water freezes on the surface of a lake but not
below it?" here
I found this very interesting and gave me one more
question which should be interesting to others
too, I hope. Question: If warmer water was
to be sent from lower down, where it is warmer, to
the surface in the form of agitated turbulence, so
the water is moving, would this stop the ice
forming, so long as the volume of water was great
enough to keep ahead of the cold air?
I'm looking at ways to keep breathing holes
open for mammals trapped beneath ice during mid
winter freezes after seeing the movie "Big
Miracle." I'm sure there must be a better way of
keeping the ice from freezing up. Even an outboard
motor should work better. So far I have thought of
lowering a grid of pipes down low and pumping air
through the pipes which are full of small holes.
The thought was that the air bubbles would bring
warmer water to the surface and therefore keep the
ice from freezing over. I still haven't been able
to find out if the water is warmer at the bottom
or half way up yet. I also thought about vertical
pipes suspended in the water, going down deep and
ending about 10 feet below the surface to insulate
the water on its way up but whales and Orcas are
likely to break the pipes and hurt themselves.
Maybe soft pipes would work? I'm not in the areas
you normally answer questions for, I'm in New
Zealand, but if someone has time to give me some
advice I would really appreciate it, so will the
whales who get trapped and die.
Thanks

interested in the explosive polymerization of

we want to be as safe as possible. Since we are

a high school fume hood be sufficient protection?
Also, how should we safely dispose of the product?

| 4552: | We find a lot of fossils today and I have heard
it is because there were different events that

the fallen bodies of the dead animals just rot?
Why did they turn into fossils if they just fell
down dead? If all of those dead animals that
are fossilized were buried rapidly with water,
etc., (which is needed for the fossilization
process) what caused that to happen with all of
the thousands upon thousands of fossilized
creatures? Was it thousands of small disasters
with water, etc? I'm just confused on that

| 4580: | My son Max is investigating which materials are
the best conductors. He built a circuit with a 6V
battery and a light bulb, hoping to distinguish
which materials are the best conductors by the
brightness of the light bulb. The experiment
worked, but the results were not satisfactory to
Max. The ligh bulb was either on or off, and it
was difficult to tell if one material was better
than the other. He asked if there was a way to
measure the conductivity of materials with another
instrument. I purchased a multimeter from Radio
Shack hoping to measure the
conductivity/resistance of the materials.
However, I am not sure I am properly operating the
instrument. We removed the test material from the
circuit and set the multimeter to the OHMS
setting. The results for the metals (copper,
aluminum foil, a nickel, and a penny) bounce all
over the place and often end at zero, and the
non-conductors do not show any change on the
screen so the end result is also zero.I would
really like to help Max find more specific
results, but I am not sure what else to do. Is
there a particular bulb that would show more
variety in the intensity? He has shown such a
curiosity about this. I sincerely hope there is a
way to help him! Thank you for your time.

| 4612: | Hello, Science Line,
Although Nitrogen can combine with chemicals to
produce unpleasant byproducts as a result of fuel
combustion (nitrogen oxides in smog, etc.), I was
wondering if atmospheric nitrogen can actually be
harnessed (somewhat like atmospheric oxygen) to
produce power in any way? Although nitrogen has a
strong tendency for inertness, since it makes up
the bulk of air, it is a shame that it cannot be
harnessed somehow -- are there any oxidizers/fuels
which can be made to react
energetically/explosively with nitrogen gas,
especially under heat and/or pressure? Thank
you very much.

then it seemed to freeze from inside out. The pool

the sides and bottom started to freeze. My science

| 4742: | Hello! I am teaching 6th-11th grade sciences. I
have a B.S. in science, but only took a year or so
of microbiology in college. Every year we have
students who want to do microbe projects for
science fair. We have good success growing
microbes in petri dishes. As yet, my best method
for measuring microbe growth is to give students a
5mm x 5mm grid which they lay on top of the petri
dish and have them estimate how much of these
boxes are filled with the microbe that has grown.
Then they add up the portions of the boxes or
whole boxes filled by the microbes and arrive at
an mm squared value. One science fair judge asked
about the height of microbe growth. I guess
students could arrive at an estimate of height by
the same method. I have done online searches
which have only yielded dilution methods. We do
not have any specialized equipment for observing
microbes in dilution, nor do I have stains for the
various microbes to show up on a microscope slide.
Any websites
or suggestions you can give a generalist 6th-12th
grade science teacher would be very much
appreciated. Thank you!

| 4770: | In alpha decay, an atom spits out two protons and
two neutrons. However, if it does not lose two
electrons as well, then it is no longer an atom,

an atom spits out an electron and an anti-
neutrino from one of the neutrons in the nucleus,
while retaining the proton from it, but if this is
true, and the atom does not somehow gain two
electrons, then there are two protons more than
electrons and it is no longer an atom. How does
this work? Also, when I was reading the answers to
the other questions about the types of decay and
how they work, I noticed that there was some

Eisenhower Middle School in Albuquerque, New
Mexico. I am doing a project in which I have to
use bio mimicry (mimicking nature to solve human
problems) to solve a food system problem. My group
and I would like to solve the problem we have that
so much water is in the world, yet very little of
it is fresh. We know that there have already been
desalination plants invented, but they aren't very
efficient. We were thinking about making a
desalination plant that is based off the salt
glands that can be found in many sea birds. This
may be a more efficient way of taking the salt out
of water. We have been doing much research over
the course of the past week, but many of the
articles and videos that we are trying to read are
too difficult for us to understand. I was
wondering if you could put in simple language the
processes used by the birds to desalinate their
water. Thank You!

| 4897: | When I raced a derby car, I was told that adding
a fender for the front side of the rolling wheels
would deflect the oncoming air (from the car's
point of view) allowing the car to go faster.
However, when I recently saw a formula for drag, I
noticed a "speed of the media" component.
Thinking through the speed of the wheel from the
body point of view, the forward surface of the
wheel above the axle is rotating into the oncoming
air at faster than the forward linear motion of
the car body, and the forward surface of the wheel
below the axle is traveling forward at a slower
rate than the body of the car (the tread touches
the track). This leads me to ask: Are fenders
only aerodynamically effective for shielding the
forward surface of the upper half of the rolling
wheel, and counterproductive for shielding the
front surface of the lower half of the rolling wheel?

| 4994: | How can a plane take off at the equator and fly to
the North Pole? When we know the equator is moving
faster than the north pole. I know part of the
reason is conservation of momentum, we keep the
momentum of the earth when we take off in a plane,
which is why a plane traveling say 300 miles per
hour can fly and get some where, even though the
earth is revolving at about 1000 miles per hour at
the Equator. So, relative to the earth we are only
traveling 300 miles per hour. That is also the
reason why when I jump in the air the earth has
not moved all of a sudden a 1000 miles in the
direction it is spinning.

a Flask was continuously filled from an Oxygen
Bottle (Welding System) at a low flow
After it was filled with the Gas a steel spatula
was lower down the neck of the flask. This spatula
was half filled with what I believe where carbon
or graphite granules.
The spatula was tapped on the inside wall of the
flask and small amounts of carbon would fall to
the base of the flask
When tapping the side of the glass and when
falling to the base of the flask, they flashed and
burnt. You could continue to do this until the
spatula was empty.
I have tried to replicate this but to no avail.
Do you know the SECRET or am I missing something

replicate this test?

to know any alternative paste that I can use
instead. If possible please give any relevant

many helpful info regarding his topic on your

procedure and test by measuring the amount of
moisture on all shirts when left outside to dry.
What would be the best way to measure the amount
of moisture? He thought about getting a soil or
wood/humidity meter but he is not sure if that
would work, he plans on sticking it to the fabric,
wrapping it around, but it might not give an
accurate reading. He did further research and
came across a portable moisture meter that is
industrial grade and is used in the textile
industry (this would really work because the
device has a ring that can be gently rubbed on
the cloth and has an indicator if its wet or dry)
but the $$$$ is way out of reach---starts at
$1200! So he saw your site and is asking for your
help on other ways to measure the moisture content
of a 100% cotton shirt. Thanks in advance for your

| 5286: | I seem to recall reading somewhere that crystal
clear sea water was not actually a good indicator
of a healthy environment from a wildlife
perspective. My understanding is that crystal
clear water is that way because it contains no
sediment/nutrients (which make the water cloudy)
and therefore, nothing for microbial life to
consume. This in turn feeds up the food chain
meaning that, while clear water appears ideal from
a human perspective, the reverse is actually true
and that it is bad from an ecological point of view?
Can you confirm this?
Thanks

science line web site. I work with Jean-Michel
Cousteau’s Ocean Futures Society (OFS) located in
Santa Barbara. I teach tropical biology programs
through OFS and the subject came up with a student
a while back about the advantage of uric acid
excretion in birds. Here is the question: since
bird embryos must live with their waste in the
egg, isn’t a big evolutionary advantage of
excreting uric acid a reduction in self pollution
of nitrogenous waste in the egg. Since water is
limited and there is no way to get rid of ammonia
or urea, uric acid is logically the best and only
safe way to deal with such waste in the egg.
I’ve looked on line and in some text books and
not been able to find an answer to this question.
Your help would be greatly appreciated.
Thanks

Sea and what they found could offer a viable
scientific reason behind the Bermuda Triangle
phenomenon. 'Multiple giant craters exist on the
sea floor in an area in the west-central Barents
Sea ... and are probably a cause of enormous
blowouts of gas,' researchers told the Sunday
Times. The craters in question were a half a mile
wide and 150 feet deep, the Daily Mail reports.
The researchers think methane leaking up through
natural gas deposits caused the craters, meaning
there wasn't just the gradual erosion but
explosions of gas as well." Do you believe this
could be a possible explanation behind the
Bermuda Triangle phenomenon?

possible to combine the electrons and neutrons so
stuff would grow out from where you are looking.
True you could\'t see it grow, that would be cool
but it would be a faster way to make stuff made
out of one material? What I'm trying to say is
that you look at a spray or whatever, it would
look white and when you look away or when it runs
out or whatever there would be a wall of whatever
element you made bigger depending on where you
looked. I hope you try, research or just honor my
request.

initially there are 5.0 moles of CO, 10.0 moles of
O2, and 1.0 mole of CO2 in a
2.0 L container and at equilibrium CO2
has a concentration of 2.5 mol/L. When working the
ICE, we determine that x = 1 which when plugged
back into the Kc expression gives us (2.5)squared
over [(.5)squared times 4]. This gives us a Kc
value of 6.25 but our answer key tells us that
the answer should be 3.125. We are wondering,
isn't the K value independent of the number of
liters, and thus our answer should not be divided

I am confused by your statement that ancient rocks
were formed at a certain time by comparing lead to
uranium ratios.
How can this be if the uranium must have been
formed in prior supernovae explosions that seeded
the nebula from whence the solar system was formed?
It seems we are ignoring the time between this
previous supernova and the forming of said rock.
Much thanks for any thoughts as this has been
bugging me for quite some time.

| 5894: | Hi,
We are currently studying atoms and the periodic
table. A student asked a question today that I
thought was quite perplexing. Since an atom is
mostly empty space between its nucleus and
electrons, what exactly is that "empty space?"
From my amateur point of view it can't be a
vacuum, can it? And, there can't be matter of any
sort because we're on such a small scale (and
atoms make up matter). Thanks for the help. Love
the site. Confused by the empty, PJ Creek 8th
grade science teacher.

We are doing a science fair experiment that
involves Music and Plants. We visited your website
and found the information useful but had a few
questions. We were wondering if you thought that a
certain genre of music would affect a plant’s
growth more than another genre. The hypothesis for
our experiment is, “If jazz, rock, and classical
music are played for four hours every day for the
first two weeks of a pinto bean plant’s growth,
then the jazz music will most positively affect
the height of the growth of the plant.” We would
like you thoughts on our hypothesis and any
suggestions you may have. Thank you for taking the
time to read this email and we hope to hear from
you soon.

| 5907: | Hi. Why can only Fe, Co and Ni be magnetic? This
question is common and on the web exist many
answers about this question. Most of these answers
pay attention to unpaired electrons of d shell. I
agree to pay attention to unpaired electrons, but
I believe there are other aspects that are as
important as unpaired electrons. In other words, I
think that unpaired electrons alone can't be
enough reason for this question. First of all it's
necessary to remember that the magnet is a
ferromagnetism material. Other aspects: Cr and Mn
have unpaired electrons more than Fe. So why can
't Cr and Mn be magnetic like Fe. We know Cr is
anti-fero-magnetic. In addition we know Mo isn't
anti-fero-magnetic like Cr. It is paramagnetic
while both of them have a number of unpaired
electrons. So in addition to unpaired electrons
there are others factors such that they are
effective in creating magnetism. What factors are
effective in creating magnetic properties? And how?

But I do not understand how in an extensional

As the valley block rotates down, do they
rotate up?
Can you help me understand rocks “rising” in an

| 5950: | I am confused and I think my questions are to
check my thinking. I did read your explanation
maybe it's the terms you don't understand. Mine is
not the terms, but maybe connecting it to a
karyotype.
So, I see 2 kinds of karyotype pictures; this
I know: \"X\" chromosomes are diploid and undergo
mitosis, 23 pairs of \"X\" in autosome cell
(non-sex cell); \"l\" chromosome is a chromosome
found in sex (somatic) cells, like Egg/Sperm;
there are only 23 chromosomes, haploid, not in
pairs. Does this make sense, or am I missing
something?
What I need explained is this:
If you look at a karyotype, KARYOTYPE #1:
sometimes you see some with a pair of \"X\" and
KARYOTYPE #2: sometimes you see a pair of \"l\".
(Look on
karyotype to see the pair of \"l\").
My question #1 is: When I see the pair of
\"X\" with 23 human chromosomes karyotype, am I
looking at non-sex cells?
Question #2: Which karyotype will you use to
determine a disorder?
To answer my own question, I think - since all
the DNA is the same in every cell, the unknown
genes wouldn't matter which cell you would look
at, but if you are looking for Turner's Syndrome,
then you would have to use a Somatic cell. Or
does it really not matter if you have somatic cell
autosome; which karyotype picture would I look
at, the \"X\" pairs or the \"l\" sex cells?
THANK YOU! Sorry for the lengthy questions,
trying to be specific and understand this
confusing thing!

anti-matter in the universe disappeared. I just
read another article that indicates this is an
active area of research. I often read descriptions
of the early universe that follow a common
progression: universe begins as a dense 1” wide
point, space is created, inflation occurs,
elements occur as universe expands and cools. So
my questions are: 1. Why is there no mention of
anti-matter in these early steps? 2. Wouldn’t we
expect it to exist as soon as elements condensed?
3. If it did exist, and if it was annihilated
through a succession of reactions, wouldn’t that
process deserve a footnote in the description of
the process? 4. How long would it take to convert
all of the matter/anti-matter into matter? 5. How
many reactions would be required to perform the
conversion? It seems we are missing an important
step in the process the early universe followed. I
understand that scientists don’t like to
speculate, but this seems like a good time to. I
have asked my friend Joel about this, but he said
we don't know. Can’t we at least acknowledge the
elephant in the room? Thanks.

| 6049: | Hi, I am a teacher for the Algebra Academy Summer
Program. Our project this year is to build and
launch hot air balloons. We try to apply some
basic math and physics to our projects. I found
the following information ZOnline: Given a
helium filled balloon surrounded by the atmosphere
(air), gravity will pull harder on the air than
the helium filled balloon. This more dense air
pushes the helium filled balloon up. I agree that
gravity is pulling on both the helium and air, but
I have a hard time understanding how gravity can
pull harder on one thing compared to another
thing. I appreciate how the on line person
explained why the helium balloon goes up, but I
need to know/ be able to explain to myself and
ultimately my students what this means (gravity
pulling harder on one thing compared to another
thing). Thank you. Johnny, Algebra Academy.

| 6053: | My name is David and I live in North Florida. I
could use some help with information to help me
with a project I have going. I am trying to
construct a VERY efficient solar oven. The oven
will mostly be comprised of three metal boxes of
different sizes, one inside another, inside
another. I intend to put them together in such a
way so that the heat from the outermost box will
be reflected toward the next box and the heat from
that box will be reflected again toward the inmost
box. I think this will concentrate the heat. The
boxes will not directly touch each other. I plan
to paint each box flat black on the outside and
put reflective aluminum foil on the surface of the
inside of each box. The question I have is this;
since the inside of the boxes will be in the dark
when the oven door is closed, will the heat still
be reflected in such a way as to concentrate it
toward the center, or does this type of reflective
action have anything to do with heat created by
light only? Does a reflective surface reflect
heat even when there is no light involved? I
would greatly appreciate any advice from someone
who knows about thermodynamics. Thank you so
much. Sincerely, David in Florida.

| 6129: | Fish gills collapse in air, so they do not have as
much surface area exposed to absorb
oxygen. However, air has a much higher
concentration of oxygen. So, can fish gills
continue to absorb oxygen through the parts of the
gills that are exposed to air? This is an
important question because many fishermen like to
catch fish and then release them. However,
fishermen have to remove the hook, which is often,
not always, easier when the fish is out of the
water, and then the fisherman may want to take a
photo of the fish out of the water before
returning it to the water. During the hook
removal and before the fish is photographed, the
fish could be dipped in the water to wet the fish
and his gills. This might also aid in oxygen
absorption and in reducing stress on the fish.
So, as long as the gills are wet, can a fish
absorb enough oxygen from the air to not suffer
undue stress before release?

| 6331: | Dear Expert, My name is Anton I am a 4th grade
student at Stratham Memorial School. I am
researching about thermal, geothermal and biomass
energy with a couple of friends. I've learned that
a snowman has more thermal energy than a hot cup
of chocolate, because the snowman is bigger. I
have also learned that conductors are the best way
to make heat. Metal is a good conductor. Rubber
and plastic are insulators. They don’t let thermal
energy pass through them easily. I learned a
very interesting fact about geothermal energy,
when tectonic plates separate some of the heat
from the earth's core rises. I also have some
questions to ask you.
1. If aluminum foil is a type of metal why doesn’t
it get hot when you use it for cooking?
2. What are the three types of heat transfers?
3. How does convection current work in a pot of
boiling water?
And last how do you make heat resistant clothes
and what do you make them out of?
Thank you for taking your time to help me
research. Please contact my teacher , or mail a
response to my school (39 Gifford Farm Rd.
Stratham, NH 03885). Thank you! Sincerely,

| 6332: | Dear someone who knows about electricity , My name
is Adriana and I am a 4th grade student at
Stratham Memorial School, in Stratham NH. My class
has been researching all forms of energy trying
the answer the question, What is energy, and how
does it affect us?
I am focusing on electricity. I have learned a
lot in my research, like electricity is in our
bodies, it makes our heart beat, muscles move and
flows through our nerves. Electricity starts with
atoms, atoms have three smaller parts in them. One
of them is called electrons. Electrons can move
very fast from one to another. Moving electrons
create energy. Moving electrons can carry
electricity to different places. This is called a
electric current. Benjamin Franklin was not the
first person to discover electricity. Someone
named William Gilbert and Sir Thomas Browne were
the first scientists to use the term electricity.
So they should get the credit for discovering
electricity, not Benjamin Franklin. I have a few
questions I hope you can answer,
1.Why does electricity conduct through metal?
2.What is electromagnetism and how does it affect
us in our lives?
3.How are electronics still using energy even if
they are plugged in but turned off?.
I really appreciate you taking the time to help
me. You can reply in a email to my teacher, in a
letter to my school, (39 Gifford Farm Rd.
Stratham, NH 03885). Thank you! Sincerely, Adriana

| 6336: | Why do you think DNA is duplicated before a cell

|
|---|
| 6337: | So when genetic crossing over occurs, DNA mixes
creating a unique verification. But where does
each half of that DNA come from, considering
meiosis happens before fertilization? Meiosis
makes either a sperm or egg cell and each sex cell
is a little different each time so where does the
DNA come from to make a sperm or egg cell? Because
just a sperm cell or just an egg cell can't grow
into a human, it must be fertilized. More
specifically, when genetic crossing over happens
where does the necessary DNA for crossing over
come from? And does meiosis happen before or after
fertilization?

theoretical) I explained to my friend that gravity
is not dependent on the atmosphere, in fact
gravity is what keeps the atmosphere from
‘floating’ away into space. I also explained that
we would still be held to the ground because of
gravity even without an atmosphere. He, however,
is of the opinion that if Earth had no atmosphere,
we would be able to bounce around – he thinks that
the atmosphere is what keeps gravity ‘in’ instead
of vice versa.

Also, I stated that molecules grow when heated, but have since changed my mind to say that the movement of molecules is affected by heat which means a hot molecule will move faster and affect its surroundings which takes up more space...indicating the heated molecule got larger. Theoretically, is the latter of the two statements above correct? Thanking you in advance.

| 6458: | Hello! I am trying to wrap my head around about the difference between Gibbs free energy and enthalpy so that I can teach it correctly. This is the mental hurdle that I can't get over: If Gibbs Free energy is supposed to account for only free energy available for work, shouldn't the value for the delta G of something be greater (more positive) than that of enthalpy, thus indicating that it is less likely to happen? I understand that this isn't the case, so I just need help with learning how to think in the correct way. Thanks! Mr. G (a science teacher).

Hello! How are you all are doing? With all do respect I have read your story online about cows that fart and burp on your website that was dated back in 2011 ( here. I wanted to let you know that not only cows fart and burp but all animals and us humans burp and fart too sometimes. Now I’m all for improving the environment and climate and healthy food from plants which provide health benefits. So why should we do something about cows when all animals and humans do the same thing? I don’t see what will solve the problem when it comes to burps and farts. Can you please email me back with an answer? I’m sorry, please do forgive me for sending this email if you all happen to not like what I wrote here. Thanks and God Bless!

| 6599: | Hi, I am an 8th grade student who is taking living environment. In the cellular respiration and photosynthesis explanation for plants, some information says the plant “makes” energy. Although it might turn stored energy into usable energy, energy cannot be created nor destroyed.What do you mean when saying that a plant “makes” energy? Just wanted to clear up any further misconceptions as it is just a minor detail that could lead to someone seeking information having the wrong idea. I appreciate your time and help your website has given me!

Since relativity predicts that moving away from an object looks at the object's past and moving toward an object looks at the object's future; and since satellites can move at high velocities (c/10,000 or higher) and look at distant objects of variable intensity (fast radio bursts), it seems that we can now confirm or refute this feature of Relativity. Right? Why haven't these experiments been done? Why is the existence of the block universe still an open question?

(I know, students bring up the oddest things.) My students suddenly turned to a very odd question that is borderline appropriate but they really want to know the answer. Here it is: Do skin cells cover the testicles on a male or are they covered in taste bud cells like those that would be found on our tongue? (I guess there are websites out there & something on Tick-Tock about how the skin on the testicles are actually made of taste buds.) I hope to hear from you because this question actually got my mind wondering....

My name is Ruby and I'm a student doing a science fair project about ice cream's melting point. My goal is to create an ice cream that has a higher melting point which will then melt less. I've been doing some research and it turns out that other people have also looked into this. I've found a lot of recipes for hot ice cream but I can't get in contact with their authors and so I was wondering if you could answer the questions I had for them. Does hot ice cream have a melting point higher than average ice cream? (Which, according to a study done by the University of California, is -3 ̊ C). Also I was wondering if you can make hot ice cream with an alternate recipe than the ones proposed?
Here are the links to the two recipes that I found:

If trapped air is left in place between the plunger and liquid, does the force necessary to expel the liquid increase at all? A disadvantage (or advantage) depending on the usage is there is obviously more plunger "play" causing it to bounce back if you let up. Just curious if the air being compressed as the plunger is pushed, is not only pushing against the liquid but to a degree, also against the plunger itself, adding to the force required to expel the liquid vs. first getting rid of the air.

| 6796: | I’m reading about antimatter and black holes. I had some random thought come into my mind about being able to utilize Lasers in space and if it would work to transmit information. Turns out technically we could use big lasers that will travel faster than the voyager satellites because the laser, obviously, would be traveling at the speed of light, and because light waves don’t dissipate in space the light could literally go on forever into space (until it hits something). So I’m just thinking, if we would have the ability to create something like the ISS or on it that utilizes solar to send multiple lasers into the void of space that can essentially be used to pick up information on how far it’s been, information around it, particles, etc. Because information can be transmitted through light, we would be able to send lasers into technically what would be the past and the what would technically be the future because hypothetically the only way to get that far in space is by traveling the speed of light. So a high frequency mega laser would literally be just that, we would be essentially be able to “time travel” but with technology. Am I crazy or could this hypothetically work?

As the elongated foot is a hallmark of bipedalism, my understanding of evolution tells me that kitty would never have evolved an elongated foot if her ancestors had never walked upright. Please help!

| 7010: | Good Afternoon,
Thank you for your wonderful website.
I had a question I would like your help with. There is an old text (a few thousand years old) which says that the amount a person can lift himself is a third of what he can carry when someone else lifts an object an puts it onto him. Could you figure out what this may have been referring to? Certainly their build (and the muscles they worked on) may have been very different than the muscles we focus on nowadays. Perhaps when one carries things on his back they are able to carry more? Thank you for your help.

| 7028: | Our son attends the College of Creative Studies at UCSB. I was hoping you could help me. I continue to find interesting rocks buried on our farm which have been uncovered while working the land. These rocks today were uncovered after my metal detector located them several feet deep. The bigger rocks look metallic, like gold, and are heavy. I read that a possible meteor was sighted in 1914 over Mission Canyon, and we live in that area (above San Roque.) Was that fall ever discovered? These lands weren’t developed until the 80’s, and our sloping land, unlike other neighbors has an interesting bowl shape and looks very different from our neighbors. meteor falls in mission canyon
Could these rocks possibly be meteorites? I’ve found legions. Google Lens identifies many of these rocks I find, many of which are sort of diamond shaped, as meteorites, dinosaur bones or Indian artifacts. I think I’m on a wild goose chase.
These rocks are a small sample of my finds. I thank you in advance for your assistance.

| 7070: | Question about Ocusoft Hypochlor and other dilute hypochlorous acid solutions used as lid scrubs. I understand how bleach works and how bacteria are killed by these products and how the product is converted to water eventually. What I don't understand is why this is non-irritating to the eyes? Wouldn't these products damage sensitive human cells and create irritation? What protects human conjunctive cells or corneal epithelial cells so this is so mild? Or is it just a matter of scale and if you had a more concentrated solution or more frequent application, it would be irritating? But if that is the case why wouldn't this be true for bacteria as well? You end up killing a small percentage of them but not the majority of them like this product seems to do?

| 7073: | I will appreciate it if someone looks over the following calculation. Thank you! So I've heard that bananas have tiny amounts of radiation in them, due to potassium, and if you eat too many bananas you can die of radiation poisoning. Of course the next logical step is to ask the question, how many bananas do I need to power my house? We start by getting two values, the radiation energy emitted by a banana and the amount of electricity the average American house needs. According to Wikipedia, a banana emits .1 microsieverts of radiation. According to the US department of energy the average American household uses 893 KWH a month. Therefore we just have to convert 893 KWH into its equivalent in microsieverts, multiply by 10, and get the amount of bananas required to power the average American house for a month.
893 KWH = 3.66 joules, one sievert is equal to 1 joule of energy, therefore we require 3.66 sieverts, which is 3.612 microsieverts, multiply by ten is 3.613 microsieverts, which means that it takes 3.613 bananas to power the average American household for a month. (That's a lot of bananas)Thank you for reading this calculation. It's probably wrong (the joule to sievert conversion is really iffy). Please correct me on any errors. Thank you :)
