In classical physics, anything driven hard enough will eventually heat up, lose coherence, and settle into disorder. A new ...

For decades, physicists have relied on the principle of symmetry to simplify and understand the complex behaviors of subatomic particles. Symmetry in physics basically means that some rules of nature ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

In a remarkable leap for quantum physics, researchers in Japan have uncovered how weak magnetic fields can reverse tiny electrical currents in kagome metals—quantum materials with a woven atomic ...

Atop Capitol Hill in June 2023, congressional representatives sat before witnesses, experts, and the media while taking in an extraordinary hearing. They watched grainy infrared video of a small ...

Here’s what you’ll learn when you read this story: For nearly a century, the magnetic anomaly of the fundamental particle known as a muon has served as a means to test theories against experimental ...
