David Armstrong studies a phenomenon that is ubiquitous in nature, yet only a few non-scientists know what it is. It’s called the weak force, or the weak interaction. Armstrong was recently named a ...

The weak nuclear force, or weak force for short, is so named because it is the direct contrast to the strong nuclear force, the attractive force that binds protons and neutrons to form the nucleus of ...

Through a one-of-a-kind experiment at the Department of Energy's Oak Ridge National Laboratory, nuclear physicists have precisely measured the weak interaction between protons and neutrons. The result ...

This video explores the three fundamental forces of the quantum world: electromagnetism, the weak force, and the strong force ...

Gravity is by far the weakest of nature’s four fundamental forces, and physicists have spent decades asking a deceptively ...

A new result from the Q-weak experiment at the Department of Energy’s Thomas Jefferson National Accelerator Facility provides a precision test of the weak force, one of four fundamental forces in ...

In our Universe, a left hand reflected in a mirror or pond appears to be a right hand. While most of the laws of nature are symmetric under reflections, obeying the same rules, the weak interactions ...

The model we have for understanding the universe’s fundamental particles is a bit like a gearbox: one tiny change to any one single particles’ properties throws off the mechanics of the other ...
