wildwood by Roger Deakin ,the modern Henry David Therou.If you wanted to borrow it teedee I'll leave it with dave budd ?.
This is a biography of the E=MC2 formula, that explains it by going through it's history and results, and fascinated me. Energy=Mass. Convert a gram of mass into the equivalent amount of energy and you get hiroshima. Amazing.
