Tunnelling between microscopic and macroscopic worlds
RICHARD FEYNMAN, one of the 20th century’s greatest physicists, once quipped, “I think I can safely say that nobody understands quantum mechanics.” Appropriately, then, a certain sense of bemusement haunted the Session Hall at Sweden’s Royal Academy of Science on October 7th, when this year’s Nobel physics prize was announced, “for the discovery of macroscopic quantum-mechanical tunnelling and energy quantisation in an electric circuit”.
