Why is the sky dark at night? Is it possible to build a shrink-ray gun? If there is antimatter, can there be antipeople? Why are past, present, and future our only options? Are time and space like a butterfly's wings? Dave Goldberg, perhaps the planet’s coolest nerd physicist, not only answers those questions, but he also reveals the most profound discoveries of physics with infectious enthusiasm and accessibility.
Dave Goldberg, an award-winning professor and director of undergraduate studies in the Department of Physics at Drexel University, writes the “Ask a Physicist” column for the popular science site io9.com and blogs at usersguidetotheuniverse.com. His new book is: The Universe in the Rearview Mirror: How Hidden Symmetries Shape Reality.
Symmetry is the unsung great idea behind all the big physics of the last one hundred years—and what lies ahead.
