On a first glance of the cover you might think that Jim Baggott and John Heilbron were brilliant Niels Bohr and Albert Einstein impersonators. In fact Baggott is an excellent popular science writer and Heilbron was an esteemed historian of science, both specialising in quantum physics. There's another way the cover is misleading - you might think this was an in-depth exploration of Bohr and Einstein's relationship. The topics they argued about certainly come into it, but instead this is detailed look at how quantum theory developed. I've read a lot of books on quantum physics, but I've never come across one that goes into such painstaking detail of every step along the way, introducing the work of a good number of physicists who rarely make it into the public eye. These range from John von Neumann - well known but usually sidelined as a quantum physicist - to the likes of Oskar Klein and Hans Kramers. Similarly, Baggott and Heilbron go into many (many) steps along the w...
