For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

For many of us, advanced physics can be tough to understand to begin with, which makes it all the more impressive whenever someone earns a Nobel Prize for advancing the field even further. The latest ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

In the 1920s, when quantum mechanics was young, physicists Jane Dewey and Laura Chalk performed some of the first experimental tests of the theory, based on a phenomenon called the Stark effect. Later ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

Ask a bunch of physicists to explain a quantum experiment and you’re unlikely to get the same description twice. Everyone agrees that the mathematical framework of quantum mechanics is peerless at ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

Today (April 14) marks 2025's World Quantum Day, an international celebration held to promote public understanding of quantum science. The date, 4/14, was chosen because 4.14 represents the first ...
