The dimensions of a physical quantity are the powers or exponents to which the base quantities are raised to represent that quantity. Note: Using the square brackets [ ] round a quantity means that we ...

Today, we can measure the position of an object with unprecedented accuracy, but the uncertainty principle places fundamental limits on our ability to measure. Noise that results from of the quantum ...

This summer, Virginia Tech physicists, in collaboration with others on the Belle Experiment at the Japanese National Laboratory for High Energy Physics (KEK), have obtained a measurement that shows ...

During the mid- to late-twentieth century, quantum physicists picked apart the unified theory of physics that Einstein’s theory of relativity offered. The physics of the large was governed by gravity, ...

A new measurement of a fundamental particle called the W boson appears to defy the standard model of particle physics, our current understanding of how the basic building blocks of the universe ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. In the last few weeks I've been working on a slightly more formal ...

A subatomic particle called the W boson may be heavier than expected, a surprising finding that might lead to a shake-up of physics' grand model of how the world works on the microscale. When you ...
