ACTION is the concept in physics that may be more fundamental than energy and entropy. It’s about time we discussed an obscure concept in physics that may be more fundamental than energy and entropy ...

Since the end of the 19th century, physicists know that the transfer of energy from one body to another is associated with entropy. Due to its fundamental importance began its rise as a useful ...

An analysis of the jumps of a hydrogen atom’s electron has yielded a new, precise value for the Rydberg constant, a fundamental quantity in physics 1. The Rydberg constant is related to hydrogen’s ...

Flawed conservation laws are consequences of a much deeper principle: Noether’s theorem. Conservation laws are among the most important tools in physics. They feel as fundamental as you can get. And ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...

What is quantum physics? Put simply, it’s the physics that explains how everything works: the best description we have of the nature of the particles that make up matter and the forces with which they ...

DEEP in a disused zinc mine in Japan, 50,000 tonnes of purified water held in a vast cylindrical stainless-steel tank are quietly killing theories long cherished by physicists. Since 1996, the ...

Sara Imari Walker receives funding from the National Aeronautics and Space Administration and the John Templeton Foundation relevant to the work in this article. She is also a member of the External ...

IN THE PAST few centuries physics has transformed both daily life and world history with novelties ranging from electricity to nuclear bombs. Physicists have also broadened humanity’s horizons, ...
