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 ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...
