Dude, you can't even spell chemistry properly, so it's not hard to be smarter than you are. But what about me or Raindawg or all the other dudes on here with PhDs. Are these guys who only have MScs or MEngs really smarter than us? If they are so smart, why'd they never do a PhD? Probably cause they weren't smart enough, that's why. So why do you accept analysis from guys who aren't very smart?
