Favorite authors: Hermann Hesse and Carl Sagan
Genghis trilogy - Conn Iggulden (I highly recommend this!
The World is Flat - Thomas Friedman
Dark Matter, Missing Planets, and New Comets - Tom Van Flandern (super difficult read, but also extremely interesting once you understand it)
Dragons of Eden - Carl Sagan
Musicophilia - Oliver Sacks (I highly recommend this!
Documents the effects of music on the brain)
Demian, Narcissus and Goldmund - Hermann Hesse
The Tunguska Mystery - Vladimir Rubtsov
I've been on this whole physics/astronomy kick for the past few years. I'll read 4 or 5 science books in a row and then force myself to read a fantasy/sci-fi or historical fiction book just to save my overworked brain
EDIT: Currently reading: Cosmos - Carl Sagan. Not as good as I expected, so far
EDIT#2: I seem to f*** up the Tom Van Flandern title every single time I talk about it. It's correct now.
