After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

The idea of relative motion is an aspect of the theory of relativity (strictly, it’s Galilean relativity, rather than ...

Condensed-matter physics and materials science have a silo problem. Although researchers in these fields have access to vast amounts of data – from experimental records of crystal structures and ...

Sam Baron receives funding from the Australian Research Council. The Matter of Everything tells the history of physics through experiments. Any book about the history of science for a general audience ...

A deceptively simple experiment that involves making precise measurements of the time it takes for a particle to go from point A to point B could cause a breakthrough in quantum physics. The findings ...

New home: the Muon g-2 ring sits in its detector hall at Fermilab, where it studies precession of muons. (Courtesy: Reidar Hahn/Fermilab) A long-standing discrepancy between the predicted and measured ...

Physicists now have a brand-new measurement of a property of the muon called the anomalous magnetic moment that improves the precision of their previous result by a factor of 2. An international ...
