I need at least 10 things silicone is used for. It's history, and how it's made. Who made silicone in the first place?

The entire process of how we make silicone would be great. In detail please.

"Procedures involving animals should be designed and performed with due consideration of their relevance to human "

What do you think this means?

From my point of view i see that animal test should be done with there relation to human and what comes 2 mind is like genetics. Animals and humans have similar genetics but still not completely similiar enough to give off accurate results

I am kind of comfortable with the idea that seas of petrochemicals like those identified on Europa could somehow end up forming the most basic forms of life i.e. the ingredients are there. I am however fascinated by the problem that if life is an inevitable consequence of the right ingredients and an awful lot of time then why there isn't more evidence of the creation of life occuring throughout history. Could oil be less the remains of many dead animals or the breeding ground of life itself. Crackpot stuff maybe but I would like to know other peoples opinions.
