The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin's Broome Bridge in 1843.

The precise imaging of many-body systems, which are comprised of many interacting particles, can help to validate theoretical ...

By using something called a quantum grid, scientists have found a clever way to simultaneously measure momentum and position ...

A strange kind of geometry governs how particles move inside matter. Now, for the first time, physicists have uncovered its full shape – and it could transform how we design materials ...

This article explores how our understanding of the universe has evolved—from the scale of everyday experience down to the ...

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

For centuries, scientific progress has depended on more precise tools for measuring the world around us. Galileo’s telescope ...

Quantum mechanics theory predicts that, in addition to exhibiting particle-like behavior, particles of all sizes can also have wave-like properties. These properties can be represented using the wave ...

In 1931, Harvey Elliott White developed a device that traced out the shapes of electron clouds by approximating solutions to ...

Why is quantum mechanics important? We are used to seeing the world at the macroscopic level. Our eye does not perceive what is really there at its microscopic level, and (maybe) it is better that way ...

Forbes contributors publish independent expert analyses and insights. Andréa Morris reports on emergent intelligence in diverse systems. “This retroactive idea. It has to be that,” says Nobel ...
