Scientists have reversed the direction of time with a quantum computer. The breakthrough study seems to contradict basic laws of physics and could alter our understanding of the processes governing
“We are not just saying that if you know the position of the electron, then you don’t know whether or not it’s moving. We’re saying that if the electron has some position, then it does not have any state of motion. What could this possibly mean? Nobody is quite sure.“
Quantum food for thought.
One mathematician who’s got first-hand experience of the fascinating interplay between physics and geometry is Shing-Tung Yau. In a new book called The shape of inner space (co-authored by Steve Nadis) Yau describes how the strange geometrical spaces he discovered turned out to be just what theoretical physicists needed in their attempt to build a theory of everything. Plus met up with Yau on his recent visit to London, to find out more.
