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

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

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

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

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

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 ...

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 ...

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 ...

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 -- ...

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 ...
