(via PBS Space Time) The mystery of what happens when we go from a superposition to a definite state is known as the Measurement Problem, and it’s arguably the most mysterious outstanding problem in ...

Despite its many successes, physicists are still struggling to nail down a coherent interpretation of quantum mechanics, as it best represents “reality”. Jim Baggott explores the arguments first put ...

When hundreds of physicists gathered on a Zoom call in late February to discuss their experiment’s results, none of them knew what they had found. Like doctors in a clinical trial, the researchers at ...

Physicists have nailed a fiendishly difficult measurement — the mass of the fundamental particle the W boson. The result, from the CMS experiment at the Large Hadron Collider (LHC), is in line with ...
