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

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

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

The Einstein-de Haas effect has been observed in a quantum fluid, showing that changes in magnetization transfer angular ...

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 ...

Albert Einstein was right about a shocking among of things, but not necessarily everything.

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

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 ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

Underneath the Danube -- Space travel -- The stuff called light. Light is a wave ; Light is particles -- Sheepdogs and Einstein's particles of light -- Einstein and his Nobel Prize -- A conflict -- ...
