^Dang, i wasn't ready to try to understand chemistry. But an classmate from long ago complained about electrons, negative charges and other stuff that i didn't really 'get' in high school. So now, I guess after i finish off this book of inventions (I'm starting "the electrical age" now) that'll probably be my next project. Biology on the other hand is so messy, I'll probably wait on that for a WHILE.^
