Read Cosmos if you want to feel the awe of the universe and understand our place in it through beautiful, sweeping prose. Read A Brief History of Time if you want to challenge yourself with the fundamental physics of space, time, and reality itself. Sagan makes you feel small in the best way; Hawking makes you think hard in the best way.
