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 ...

When it comes to building particle accelerators the credo has always been “bigger, badder, better”. While the Large Hadron Collider (LHC) with its 27 km circumference and €7.5 billion budget is still ...

Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

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 ...

In 2015, the world's most powerful atom smasher, the Large Hadron Collider, will restart. The particle accelerator has already discovered the Higgs boson, the so-called "God particle," and when it ...

Physicists have started running the world's largest particle accelerator at a new record energy and taking the first data from these ultra-powerful collisions. Protons zoom around the 17 mile (27 ...

Having good neighbors can be very valuable—even in the atomic world. A team of Amsterdam physicists was able to determine an ...
