^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.^
