Brownian motion is a phenomenon where fine particles suspended in a liquid or similar medium continue to move irregularly. It ...

Paul Halpern’s The Great Atom Debate tells how physicists Ernst Mach and Ludwig Boltzmann battled over atoms, atomic theory, ...

A fluid is a substance that has the property of flowing. Water and air are not single, large masses. They are made of ...

The objects you interact with every day are predictable – you can pick up a box, sit down in a chair without falling to the ...

Physicists have achieved a long-sought goal in demonstrating quantum entanglement using the momentum of atoms, rather than their internal states. Since atoms’ momentum can be affected by gravity, this ...

Researchers observe atoms trapped in an optical lattice mimicking particles created in a strong electric field.

A team studied some of the smallest particles in the Universe on the nation’s fastest computer, Summit at Oak Ridge National Laboratory. Scientists use particle accelerators to speed up electrically ...

If you were to take any object in the Universe that's made of normal matter ⁠— anything a human being could touch, see, or otherwise detect an interaction with using our bodies ⁠— you'd find that you ...

Particles engineered to spontaneously self-assemble like atoms forming molecules could give rise to new high-tech materials, leading to better optical displays and faster computer chips, researchers ...

Quantum mechanics boasts all sorts of delightfully odd features. There's the fact that two separated particles can interact instantaneously, a phenomenon called quantum entanglement. (Einstein ...

In 1937, US physicist Isidor Rabi introduced a simple model to describe how atoms emit and absorb particles of light. Until now, this model had still not been completely explained. In a recent paper, ...
