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 ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their ...

The Muon g-2 experiment (pronounced “gee minus two”) is designed to look for tantalizing hints of physics beyond the Standard Model of particle physics. It does this by measuring the magnetic field ...

Researchers in Europe have developed a technique for obtaining accurate laser-based measurements of objects hidden behind complex scattering structures. They say that their mathematical formula, which ...

The W boson is heftier than anyone expected. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. An ultraprecise measurement of the mass of a ...

From fundamental physics related to Einstein's special theory of relativity to fundamentals of metrological applications in the range of thousandths of micrometers (i.e. nanometers) - the bandwidth of ...

Three scientists won the Nobel Prize in physics Tuesday for research on the strange behavior of subatomic particles called quantum tunneling that enabled the ultra-sensitive measurements achieved by ...

It’s a powerful technique, but small uncertainties at each step can add up, something critics argue may be behind the Hubble tension. The new study bypasses this entire ladder using a method called ...

We're getting something wrong about the universe. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. We're getting something wrong about the ...

The physicists Alain Aspect, John Clauser and Anton Zeilinger have won the 2022 Nobel Prize in Physics for experiments that proved the profoundly strange quantum nature of reality. Their experiments ...
