Cracking a 15 year physics mystery, researchers measured the precise size of a proton. In A Nutshell A team in Germany used an unprecedentedly precise laser measurement of hydrogen to pin down the ...

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 ...

Precision measurements in atomic and ion physics have become a cornerstone for testing the limits of our understanding of quantum electrodynamics (QED) and the Standard Model. By harnessing ...

Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun’s gravity, and their technique promises a major ...

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 ...

Compared to scribbling mathematical expressions for entangled quantum states on a sheet of paper, producing real entanglement is a tricky task. In the lab, physicists can only claim a prepared quantum ...

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 ...

Superconductors are among the most puzzling materials in physics. They conduct electricity with zero resistance, but only ...

Balancing act The two systems of measurement – imperial and metric – are often used together in UK shops. (Courtesy: iStock/Paolo Paradiso) When I was at primary school in the 1960s, measurements were ...
