In January I wrote a piece titled “ 5 Physics Equations Everyone Should Know .” Lots of you weighed in with your own nominations, and there were plenty of good suggestions. So I’ve decided to do a ...

Irish physicist William Rowan Hamilton’s pioneering work contained hints of the enigmatic wave–particle duality that governs the universe.

What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred years, physics has rested on two foundational theories. Einstein’s general ...

When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the ...

Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

Researchers have made a breakthrough in applying the first law of thermodynamics to complex systems. The law is a bedrock of physics, but has long failed to describe systems that are out of ...

"With this, we can detect very tiny changes in both position and momentum at once, beyond the limit of any classical sensor," the authors explained.
