I'm doing a speech about why I dislike PETA, and I can't find any books about it anywhere!

Any advice?

(It's required that we have at least two books in our bibliography.)

How do we prove that the limit of (1-1/n)^n=1/e as n goes to infinity assuming that we already know that the limit of (1+1/n)^n=e as n goes to infinity?

I'm trying to build a robot that drives on the ground and occasionally encounters a wet surface. I need to improve traction to handle the wet surface. My immediate intuition leads me to simply widen the tires, but knowing F = uN, I don't see how surface area of the tire helps any? I know increasing the coefficient of friction or the normal force will improve traction but could someone enlighten me as to what effect a wider tire would or would not have. Thanks.

I am currently extracting potassium chlorate from paper strike on box white match heads. I soaked 7225 match heads in some water overnight to remove all the white stuff off the paper and then put the white watery mixture on a plastic pan to evaporate the water, after all the water is evaporated there should be some crystal on top of the pan, after these crystals are scraped off it should be somewhat pure potassium chlorate. My question is: Can potassium chlorate ignite by a small amount of friction(such as when I scrape it off the pan), or by a small impact(such as if I were to put a gram of it in a container and then drop the container from a few feet above the ground?Are there any chemicals in white paper match heads that are strike on the box that would make it more sensitive? What are the precautions I should take when dealing with this stuff? I know not to mix with sulfurs or phophides because it'll make it even more sensitive.

the donor?

I'm serious! No TV shows, S/F novels, rumors, speculations, please!

Any response beginning with "you don't understand!" will not even be read. If I understood, I would not have to ask.

Any licensed doctors, medical students out there who know about this...?

There's RNA being physically transferred, isn't there...?

Isn't at least some of it memory RNA...?

What sort of evidence for/ against transfer of specific memories (learned information) is there?

What sort of evidence for/ against acquisition of personality or character traits is there?

Thanks to all serious answerers.
