Query: Couldn't put it down

I bought the book at an airport and read it in 3 days. I was amazed at how interested I became once I started reading the first page. I'm not a science buff, by any means, but I am intersted in general knowledge of the way things work. How many people can honestly say they know what E=MC2 means? Well, thanks to this book, now I can.After I finished, I gave it to my father-in-law and he couldn't put it down. The people and the stories behind each part of that equation are fascinating. The section on the race to develop the atomic bomb between the U.S. and the Nazis was especially a page turner.Well done, David Bodanis, and thanks for the insight!
