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 ...

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 ...

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 ...

Over the short span of just 300 years, since the invention of modern physics, we have gained a deeper understanding of how our universe works on both small and large scales. Yet, physics is still very ...

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, ...
