The cat that wouldn't die
The weird paradox of Schrödinger’s cat has found a lasting popularity. What does it mean for the future of quantum physics?
Earlier in 1935, Einstein and his Princeton colleagues Boris Podolsky and Nathan Rosen had published a landmark paper arguing that quantum mechanics could not be considered a complete theory. The cat paradox was limited to one paragraph in a lengthy review article, and Schrödinger’s dissent cut little ice with the majority of physicists, including those who spent time pondering on the meaning of quantum theory. As Le Guin herself observed in her short story, there appears to be nothing special about the act of lifting the lid, and quantum mechanics is silent on the question of where in the chain of events the weirdness stops.
