I like math books.
Polya and Szego's Problems and Theorems in Analysis
Ireland and Rosen's Classical Introduction to Modern Number Theory
John Waynard Milnor (I hope I spelled the name correctly) Topology from the Differentiable Viewpoint.
Not like I've actually read any of those books (beyond the first few pages lol), but they are dead sexy math books and I'd like to be able to read more of them.
