Quantum mechanics rule ‘bent’ in classic experiment
He explained to BBC News that “while the uncertainty principle does indeed forbid one from knowing the position and momentum of a particle exactly at the same time, it turns out that it is possible to ask ‘what was the average momentum of the particles which reached this position?'” .
“You can’t know the exact value for any single particle, but you can talk about the average.”
Ummm… neat?
