physics: The ultimate no-brainer

PHILIP BALL

John Cage's composition 4' 33" is a piano piece that is performed by not 
performing. The pianist goes through all the preliminary motions, but sits 
in silence for 4 minutes and 33 seconds — after which, one assumes, the

works in the same spirit — to give the answer without ever being switched on1.
