Quantum physics

Richard Feynman's famous diagrams weren’t just a way to do calculations. They represented a deep shift in thinking about how the universe is put together.

Suchitra Sebastian’s searches for quantum anomalies have led to the potential discovery of a new building block of matter.

An experiment claims to have invalidated a decades-old criticism against pilot-wave theory, an alternative formulation of quantum mechanics that eliminates the most baffling features of the subatomic universe.

How quantum entanglement connects with the “many worlds” of quantum theory.

The cognitive scientist Donald Hoffman believes that evolution and quantum mechanics conspire to make objective reality an illusion.

In a virtuoso experiment, physicists have revealed details of a “quantum critical point” that underlies high-temperature superconductivity.

Three computer scientists have solved a problem central to a dozen far-flung mathematical fields.

Einstein refused to believe in the inherent unpredictability of the world. Is the subatomic world insane, or just subtle?

Explore the deepest mysteries at the frontier of fundamental physics, and the most promising ideas put forth to solve them.
