The race against Hitler to build the first nuclear bomb

From our UK edition

Ettore Majorana vanished in March 1938. According to Frank Close in Destroyer of Worlds, the 31-year-old Sicilian physicist ‘probably understood more nuclear physics theory than anyone in the world’, and was hailed by Enrico Fermi as a ‘magician’, in the elevated company of Newton and Galileo. Majorana was also an ardent fascist; yet he was haunted by the destructive potential of his work on mapping the nucleus. His disappearance – perhaps a suicide; more likely a new, incognito life in South America – has been related to an anguished remark he made to a colleague: ‘Physics has taken a bad turn. We have all taken a bad turn.

Know better

We live at a time of universal polymathy. We don’t know everything, but there’s not much difficulty in being able to discover any given truth. But it’s also worth remembering just how hard it used to be to find things out. Thirty years ago if you wanted to research it meant a trip to the public library — and perhaps filling out a form for an inter-library loan. Or you could try your luck in a bookshop, new or secondhand. The whole process took a long time, and most people stayed within their professional competence or enthusiasm, frankly admitting to ignorance outside those limits. It was the age of the specialist, memorably captured by Michael Frayn in Donkeys’ Years and the character of Kenneth Snell.
