No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

Holger Müller is in the Department of Physics, University of California, Berkeley, Berkeley, California 94720, USA. However, the recoil energy is tiny and therefore hard to measure. Laser-based ...

Learn about the Standard Model of particle physics and how physicists use it to predict the (subatomic) future. In ancient times, Greeks interested in forecasting the future would voyage on the ...

The Standard Model is one of the most well-tested theories in particle physics. But scientists are searching for new physics beyond it. Humans have always sought to understand the essence of the world ...

The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...
