In his review for The Sunday Times (January 11, 2009) of a new book on the life of quantum physicist Paul Dirac, The Strangest Man: the Hidden Life of Paul Dirac, Quantum Genius The Strangest Man: the Hidden Life of Paul Dirac, Quantum Genius by Graham Farmelo of the Science Museum of London, John Carey begins by noting that Paul Dirac was the greatest British physicist since Newton:
In the 1920s and 1930s, together with Bohr, Heisenberg, Schrödinger and Pauli, he opened up the field of quantum physics, changing the course of science. In 1933, aged 31, he became the youngest theoretician to win a Nobel prize.
However, according to Farmelo, the reason there was no biography of Dirac until now is that he was
pathologically silent and retiring, and as a thinker he was unintelligible except to mathematicians. Even his fellow physicists complained that he worked in a deliberately mystifying private language. For his part, he insisted that the quantum world could not be expressed in words or imagined. To draw its picture would be “like a blind man sensing a snowflake. One touch and it’s gone”. Its beauty revealed itself only in mathematical formulae.
Actually about the quantum world, Dirac is certainly right, and certainly
not the only person to think so. As the Stanford Encyclopedia of Philosophy says, “the real difficulty in understanding quantum mechanics lies in coming to grips with their implications — physical, metaphysical, and epistemological.”
