Daniel Shaddock is co-founder of Liquid Instruments and professor of physics at the Australian National University in Canberra. He spoke with Hamish Johnston about innovation in the test 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 ...

To operate fusion systems safely and reliably, scientists need to monitor plasma fuel conditions and measure properties like ...

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 ...

Here at Physics World we’re planning to publish special issues later this year on time (in July) and on SI units and measurement (in November). So to find out more about the latest work in these ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

The National Academies Panel on Assessment of Selected Divisions of the NIST Physical Measurement Laboratory will assess the scientific and technical work performed by the NIST Physical Measurement ...

Researchers at Fermilab have made a measurement that could mean that scientists have to rethink their understanding of the rules that govern the subatomic world. Muons are ephemeral subatomic ...

Since 1959, the National Institute of Standards and Technology (NIST) has annually commissioned the National Academies of Sciences, Engineering, and Medicine to assess its various measurements and ...

During the mid- to late-twentieth century, quantum physicists picked apart the unified theory of physics that Einstein’s theory of relativity offered. The physics of the large was governed by gravity, ...

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...
