Some years ago John Kenneth Galbraith wrote in an essay on his efforts at writing a history of economics: ‘As one approaches the present, one is filled with a sense of hopelessness; in a year and possibly even a month, there is now more economic comment in the supposedly serious literature than survives from the whole of the thousand years commonly denominated as the Middle Ages … anyone who claims to be familiar with it all is a confessing liar.’ I believe that all physicists would subscribe to the same sentiments regarding their own professional literature. I do at any rate.
