Heisenberg's uncertainty principle graces every undergraduate quantum physics textbook in the world. But a proof for a key aspect of it - one that encapsulates the uncertainty that measurement introduces into a system - has never been proven directly. That has just changed... http://www.nature.com/news/proof-mooted-for-quantum-uncertainty-1.13270?WT.mc_id=PIN_NatureNews
Scientists cast doubt on Heisenberg's uncertainty principle
Heisenberg's Uncertainty Principle has bedeviled quantum physicists for nearly a century, until recently, when researchers at the University of Toronto demonstrated the ability to directly measure the disturbance and confirm that Heisenberg was too pessimistic.
