The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one.

In the 1990s, the Liquid Scintillator Neutrino Detector (LSND) in Los Alamos, New Mexico, found a weird anomaly during its experiments on tiny elementary particles called neutrinos. It found far more ...

In the literal sense, nothing is simpler than an elementary particle: By definition, a particle is considered to be elementary only if there is no evidence that it is made up of smaller constituents.

Without elementary particles, there'd be no X-Ray machines, no Internet and no electricity. Because some elementary particles penetrate matter without destroying it, they're a boon for scientific and ...

The building blocks of matter that have been experimentally verified are the quarks and leptons described by the Standard Model. Since the discovery of the electron in 1897, physicists have identified ...

THE discovery of different kinds of mesons with rest-masses spreading over a considerable range has brought about a fundamental change in the aspect of the problem of elementary particles. It looks as ...

RECENTLY J. Barnóthy 1 has proposed an explanation of the elementary particles (protons, electrons, etc.) in terms of serial universes, each enclosed in one of higher order. The elementary particles ...
