This is his second book. I finished this book around the same time I was watching the new Cosmos series on Fox. (It's hard to believe that Seth McFarlane, the man behind Family Guy, is one of the producers of the new Cosmos. I'm still waiting for Stewie to show up, or for a Cosmos parody on Family Guy. But I digress.) Like Carl Sagan and Neil Degrasse Tyson on Cosmos, Brian Greene is attempting to make science understandable to those of us who don't have advanced science degrees. Dr Greene uses a lot of pop culture references to illustrate his points. He seems to have a special fondness for the Simpsons. It's a little more complex, though. He's trying to explain the basics of string theory, with its theories of 10-dimensional space and quantum lengths. It can be a little slow going at times. He saves most of the mathematical equations for the footnotes. I'm not sure it's fully understandable to everyone. I had trouble with it myself. Some updates from the text. The large Hadron collider was finished, and the Higgs particle was discovered. Also, scientists recently discovered ripples from the original big bang. Dr Greene knows about pop culture. (He's appeared on the TV show The Big Bang Theory making fun of himself.) He does well in this book. It's just the subject matter that can be daunting.
