In 1905, 100 years ago, Einstein experienced what we now call his “miracle year”, during which he published three seminal works in physics that opened the door to quantum mechanics and relativity. NOVA, the excellent PBS science program, celebrates this achievement with their program “Einstein’s Big Idea”:http://www.pbs.org/hplink/redir/wgbh/nova/einstein/, airing tonight on PBS. This program, based on the book “E=mc2” by David Bodanis, explores the development of the famous equation E=mc2, which is actually the short form of the relativistic energy conservation equation,
