This video provides a simple explanation of symmetry and gauge theory, focusing on their foundational role in physics. It ...

A century since Werner Heisenberg changed the course of physics, five of the world’s leading physicists examine the greatest achievements of quantum mechanics and look forward to the next 100 years, ...

Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line from one point to another. That seems obvious, because in the world we see ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

Quantum mechanics depicts a counter-intuitive reality in which the act of observation influences what is observed — and few can agree on what that means. Everyone has their favourite example of a ...
