Every so often, someone puts out a science book that everyone buys and nobody reads (examples: A Brief History of Time, A New Kind of Science). Genius physicist Brian Greene doesn't write that kind of science book. His books—The Elegant Universe is the best-known one—explain string theory and the cosmos in accessible language that even Sarah Palin could understand. His newest, The Hidden Reality, covers Star Trek–worthy ideas (like parallel universes) that suddenly don't seem so unbelievable, thanks to recent scientific breakthroughs. Get your head fucked by science! (Town Hall, 1119 Eighth Ave, 800-838-3006, 7:30 pm, $5)
