A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

The Einstein–de Haas effect, which links the spin of electrons to macroscopic rotation, has now been demonstrated in a ...

A groundbreaking quantum experiment conducted by MIT physicists has turned a major page in the long-standing debate between Albert Einstein and Niels Bohr. Their recent work, published in Physical ...

Quantum mechanics is very impressive. But an inner voice tells me that it is not yet the real thing. The theory produces a good deal but hardly brings us closer to the secret of the Old One. I am at ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

Add Yahoo as a preferred source to see more of our stories on Google. Einstein–Rosen bridges are not wormholes but quantum links between opposite directions of time, offering new insight into black ...

A hundred times more than relativity theory -- "An act of desperation" -- The impudent Swabian -- The gypsy life -- Two pillars of wisdom -- The perfect instruments of the creator -- More heat than ...

A cluster of 7,000 sodium atoms has just been coaxed into behaving as a single, ghostly wave, stretching quantum weirdness ...

On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...
