The last time I read a book that talked about protons, neutrons and electrons, it was my GCSE Double Award Science textbook. It is certainly not a book I remember with any fondness; rather the thought of it brings back the feelings of sheer terror induced at failing to recall in the exam that FE actually stands for iron and not Forgotten Element. So it was with trepidation that I embarked on E=mc²: A Biography of the World’s Favourite Equation by David Bodanis. The introduction to the book immediately put me at ease: it tells of an interview with Cameron Diaz where she says she would like to know what E=mc² really means. This reassures me; if the book was written with Hollywood celebrities in mind (who, let’s face it, are not renowned for their scientific knowledge), surely I should be able to keep up.
And I could! Bodanis takes each of the equation elements in turn, and in his accessible, conversational tone explains its discovery. He offers interesting biographical details of each of the international scientists involved, including historical contexts from the French Revolution to the Second World War and beyond. At the same time he explains the practical applications of the theory: how the atom was finally split and why this lead to the development of the atomic bomb, and what the final moments of the earth will look like if anyone survives to see them. I found myself proudly holding the book at 180 degrees from my face so all my travelling companions could see that I was getting through a science book. And what’s more, understanding and enjoying it! David Bodanis has replaced my fear of science with a smug knowingness. I’m not sure my colleagues will thank him.
