Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you want to probe the frontiers of fundamental physics, you have to ...

If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

Fast-moving protons are much more likely to pair up with fast-moving neutrons than with other protons in the nuclei of atoms, according to a recent experiment performed at the U.S. Department of ...

According to the classical model of nuclear structure, the internal structure of nucleons should not change if they are bound into atomic nuclei. But it was discovered 35 years ago that quarks inside ...

Inside the nucleus of some atoms, protons appear to be doing very unexpected things. They are pairing up far more often than usual when they get extremely close to each other, and physicists don’t ...

Fast-moving protons are much more likely to pair up with fast-moving neutrons than with other protons in the nuclei of atoms, according to a recent experiment. The research confirms a previous ...

Individual protons and neutrons in atomic nuclei turn out not to behave according to the predictions made by existing theoretical models. This surprising conclusion, reached by an international team ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

Physics Professor Manuel Calderón de la Barca Sánchez and his students are using the largest and most complex machine ever built to probe the strongest force in nature at the tiniest of scales. “In a ...

THIS book is a revised and enlarged edition of Prof. Millikan‘s book "Electrons" which appeared in 1935, and was itself based on his celebrated work "The Electron" (1917), which in its day occupied a ...
