A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science's most ...

Physicists are using quantum computers to simulate high-intensity electromagnetic interactions to test the limits of light ...

This lesson explains motional electromotive force on a curved track and how motion through a magnetic field can generate voltage. We break down the physics behind the concept and walk through the key ...

The optical properties of metallic nanoparticles with nanometre dimensions exhibit features that cannot be described by classical electrodynamics. In this quantum size regime, the near-field ...

On the big screen, in video games and in our imaginations, lightsabers flare and catch when they clash together. In reality, as in a laser light show, the beams of light go through each other, ...

An international team has demonstrated a new method for producing the most intense light ...

There’s an awkward, irksome problem with our understanding of nature’s laws which physicists have been trying to explain for decades. It’s about electromagnetism, the law of how atoms and light ...
