Book review - "E = mc2"

Biography of the famous equation which tries to put it in simple terms. I kind of understood it by the end of it but admit i know very little about science - the writer does a good job. We meet many colourful personalities - not just Einstein but Voltaire and a surprising amount of women (women really kicked butt in science circles). The climax involving the race for the atomic bomb is very exciting. And depressing. Lovely word in the author's note: "I loved writing this book".
