Da Vinci. It's Italian — not that that probably means much to you. And what didn't he do. Imagine a guy so fascinated by the world around him that he was trying to figure out every single thing he could, and he kept using all those things to help him figure out other things. The guy was a painter, but he was also interested in anatomy. Took apart a bunch of corpses, too, figuring out how muscles and bones worked. But then, you figure out how an arm works, you can draw it a lot more accurately when you paint.

[Seriously, he's not about to sit here and adoringly list off da Vinci's many accomplishments the way SOMEONE ELSE might, but he'll give the guy credit for being the genius he was.]

You compare someone to da Vinci, you're saying that they're a genius inventor and scholar years ahead of their time. That's who he was.
