I picked up The Road to Reality: A Complete Guide to the Laws of the Universe by Roger Penrose, for the third time. It's really interesting and well written, but I still feel it's a pretty heavy read. I figure that I'll get through it with Sal Khan's help, when I hit math and physics that's above my level. I hope it will be a good way for me to improve my math, while learning about our history and the universe all at the same time.
