Conversion of Units: Unit conversion is a multi-step process that involves identifying the starting and desired units, finding the appropriate conversion factors, and strategically using ...

In the last few weeks I've been working on a slightly more formal version of this post on black-body radiation for use in something else. One of the tricky things in writing about the development of ...

The Muon g-2 Collaboration has doubled the precision of their 2021 measurement of the muon’s magnetic moment and it disagrees with the predictions based on the standard model of physics. Muons are ...

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 ...

From pacing out distances with our feet to defining the kilogram by the Planck constant, measurement has come a long way. Across history, humans have sought consistent ways to compare, quantify, and ...

New measurements of a subatomic particle provide the strongest hint yet that the leading theory of quantum physics that explains our universe may be missing a fundamental element, scientists say. The ...

Today, we can measure the position of an object with unprecedented accuracy, but the uncertainty principle places fundamental limits on our ability to measure. Noise that results from of the quantum ...

For over a decade, confusion over the size of the proton has held scientists back. Disagreeing measurements of the subatomic particle’s radius meant that scientists couldn’t test one of their key ...

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 ...

On April 7, particle physicists all over the world were excited and energized by the announcement of a measurement of the behavior of muons—the heavier, unstable subatomic cousins of electrons—that ...
