More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

A century ago, science went quantum. To celebrate, physicists are throwing a global, year-long party. In 1925, quantum mechanics, the scientific theory that describes the unintuitive rules of physics ...

U.S.-based scientists John Clarke, Michel Devoret and John Martinis won the 2025 Nobel Prize in Physics for "experiments that revealed quantum physics in action", paving the way for the development of ...

In 1925, a young German physicist fled to the treeless island of Helgoland in the North Sea to ease a severe bout of hay fever. With nothing but daily walks and long swims to distract him, 23-year-old ...

Quantum mechanics is a fundamental branch of physics that describes the behavior of matter and energy at the smallest scales—typically at the level of atoms, electrons, photons, and subatomic ...

In 1900, German theoretical physicist Max Planck accidentally gave birth to the field of quantum mechanics (aka quantum physics) when he tried to investigate why the results of his black body ...
