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 ...

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

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 ...

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

Scientists working on Fermilab's Muon g-2 experiment released the world's most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown ...

“It’s not maths that makes physics a science. It’s the fact that you measure things,” says Michael de Podesta in this week’s Physics World Weekly podcast. De Podesta is in conversation with Physics ...

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 ...

The 50-foot-wide racetrack used to study muons traveled by barge around Florida and up the Mississippi, and then by truck across Illinois. Reidar Hahn, Fermilab About 50 years ago, physicists came up ...

A new measurement of a fundamental particle called the W boson appears to defy the standard model of particle physics, our current understanding of how the basic building blocks of the universe ...
