Check out this link for the Time Travel cheat sheet. I saw it posted on Gizmodo and had to share it because it's something I've often thought about. If you went back in time and just used the basic knowledge you had then you could take credit for inventing all sorts of crap! You'd be the world's smartest person without any of the pesky schooling or years of research to come up with one remarkable find.
It's got all the basic knowledge you need to be king of the world when you go back in time and leap-frog other people's intelligence to become an Einstein in your own right.
Just the JPG
It reminded me of this Ben Stiller Show clip that shows what would actually happen if most people went back in time. Enjoy!
