Love and Math by Edward Frenkel

This book is a book of passion for math. It is about a mathematics that is very abstract and theoretical. It is about math at the level of just a few brilliant mathematicians. Nevertheless, Frenkel tries to "explain" his work. He basically tells his life story beginning with his math education which is almost thwarted by anti-semitism in Russia. Along with the story he explains enough math so you can at least glimpse the difficulty and importance of what he is doing and the joy of conquest. He starts with groups and symmetry and moves to manifolds, dimensions, and branes to introduce the Langlands Program, a kind of unification of mathematics that amazingly is turning out to be "symmetrical" with cutting edge quantum physics. He believes math discovers self-existent truths that are not human inventions.
