It was another great Book Group outing. We went to hear Brian Greene, author of The Elegant Universe and The Fabric of the Cosmos at Monroe Community College. He was asked to lecture as part of their celebration of World Physics year--the 100th anniversary of Einstein’s landmark theory of relativity. I avoided physics at both the high school and college levels (now a regret), and know zip zero about physics. Brian Greene was articulate, entertaining, and absolutely understandable. Not that I could explain what he said, but I did understand it. I now have a reasonable sense of the difference between the theory of relativity, quantum mechanics, and string theory--and how they relate to one another. Greene made great analogies and had wonderful video clips that provided visual images of the abstract concepts. He is an amazing speaker. If you ever get a chance to hear him talk, don’t miss it.
