How would you feel if you were in a quantum superposition, asks Carlo Rovelli in his article “Why quantum is relative” (13 March, p 36).
That is easy enough to answer. I am in a superposition every Friday night, having played the lottery but not looking at the results until Saturday morning. On Friday nights, I am in a superposition of both being a lottery millionaire and also the same old wage slave. The consequences are that one does wake up in a bit of a daze – or is it a hangover?
