1.	Are lithium polymer batteries dangerous? Why?
2.	What are your views on pesticide use? Do you think their use is dangerous to the environment? If so, what do you suggest we do to decrease pesticide use?
3.	Um, I bet this question is going to be common sense, but i have always wondered about it. How does something that is concrete, is it able to become an electronic file stored on a computer? How does a simple code make something happen on a computer?
4.	Hi, I read an article the other day about an artificial retina that nanotechnologists have recently created. I really liked it and all, but I was wondering how something like that could work. My sister who is in college now told me about brain input and output signals that are recived from electronic sources, such as the artificial retina. How would a blind person be able to "remember" what they saw with the artificial retina? If the artificial retina does not have direct contact with the part of the brain that stores information, how is seeing something, and (knowing you have seen it) possible?
5.	Hi! How could I, (or what would I need, too) to make a relatively simple search engine of my own?
