Step inside the strange world of a superfluid, a liquid that can flow endlessly without friction, defying the common-sense ...

Planck's constant is one of the fundamental constants that sets up all the "rules" for how things work in our universe. (It’s named after the theoretical physicist Max Planck, who is best known for ...

Later work by others built on this, showing that these energy levels are a fundamental part of how the universe works at the smallest scales. It was a huge step in moving away from older ideas about ...

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 ...

Quantized conductance — whereby the current through a wire changes in a stepwise, rather than continuous manner — has been seen in very narrow ribbons of graphene for the first time. The discovery was ...

For decades, physicists have struggled to develop a quantum theory of gravity. But what if gravity — and space-time — are fundamentally classical? Most physicists expect that when we zoom in on the ...
