What is temperature? What is heat? To know the answer, we must enter once again from the visible world into the invisible ...

Add Yahoo as a preferred source to see more of our stories on Google. Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage Team ...

In 1931, physicist Hans Bethe predicted that, in certain one-dimensional quantum systems, particles can bind together to form ...

Scientists have physically realized Bethe strings, creating stable one-dimensional atomic chains using ultracold cesium atoms ...

Researchers at the Swiss institutes of ETH Zurich and Paul Scherrer Institute (PSI) in ...

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 ...

Until now, atoms have never been imaged interacting freely in space, but a new technique known as non-resolved microscopy has changed that. MIT physicists were able to successfully capture images of ...

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 ...

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, ...

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 ...

The big idea of atomic theory is that, at some smallest, fundamental level, the matter that makes up everything can be divided no further. Those ultimate building blocks would be literally ἄ-τομος, or ...
