Thank you. It should have occurred to me that this question would have been asked before. That second list looks particularly interesting. My dad knew a guy back in college who dropped out, but before he did he went to all his professors and asked for a list of the 10 most important books in their respective subjects. I think the dude became a CEO or something eventually.
Asking the same question is completely fine (even encouraged!), just thought it'd be useful to provide you with some that may or may not be posted this time around.
Much appreciated. By the way, have you read Chaos by James Gleick? It's an exposition on Chaos Theory for the layperson (which I realize you probably aren't after glancing at your profile). He goes pretty in depth about Hendrik Lorentz and the origin of your username.
