For a few years, one of particle physics’ most unsettling numbers seemed to be pointing somewhere strange. The trouble ...

Scientists from collaborations at Fermilab, CERN and Brookhaven National Laboratory have won the 2026 Breakthrough Prize in ...

For the first time, scientists have measured the 'shape' of an electron in solids, opening the door to advances in quantum ...

A decade-long effort to measure one of physics’ most fundamental constants culminates in a moment of uncertainty and ...

After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest ...

This morning on BBC Radio 4, the mathematician Roger Penrose, physicist Basil Hiley, and philosopher Simon Saunders had a lively discussion about the “measurement problem in physics” with broadcaster ...

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 ...

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 ...

Recently in my physics lab, students were having trouble with the difference between mass and weight. I had ready answers---it’s a topic I’ve gone over hundreds of times. But after I explained that ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science's most ...
