Quantum theorem shakes foundations | Nature News & Comment 2011-11-17

The wavefunction is a real physical object after all, say researchers.


At the heart of the weirdness for which the field of quantum mechanics is famous is the wavefunction, a powerful but mysterious entity that is used to determine the probabilities that quantum particles will have certain properties. Now, a preprint posted online on 14 November1 reopens the question of what the wavefunction represents — with an answer that could rock quantum theory to its core. Whereas many physicists have generally interpreted the wavefunction as a statistical tool that reflects our ignorance of the particles being measured, the authors of the latest paper argue that, instead, it is physically real.

“I don't like to sound hyperbolic, but I think the word 'seismic' is likely to apply to this paper,” says Antony Valentini, a theoretical physicist specializing in quantum foundations at Clemson University in South Carolina.

Valentini believes that this result may be the most important general theorem relating to the foundations of quantum mechanics since Bell’s theorem, the 1964 result in which Northern Irish physicist John Stewart Bell proved that if quantum mechanics describes real entities, it has to include mysterious “action at a distance”.

TERRA 433: Papiroflexia PREVIEW

And now for something wonderfully different! Papiroflexia (Spanish for “Origami”) is the animated tale of Fred, a skillful paper folder who could shape the world with his hands. Joaquin Baldwin used Photoshop and AfterEffects to create this fanciful animation that may resonate with many of us who would like to mold the human world into one just a little more natural.
