When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

How is it possible for the ISS to stay in orbit? Learn more about the science behind orbiting Earth and more in this NASA ...

Spintronics is an emerging field that leverages the spin, or the intrinsic angular momentum, of electrons. By harnessing this quantum-relativistic property, researchers aim to develop devices that ...

Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...

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 ...

The article explores how the Big Bang initiated the universe's continuous motion, affecting vast cosmic distances through expansion. Angular momentum drives local rotations, while dark matter ...

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...

We live and die by data these days. Data rates and latencies are everything, with data centers and chips designed to maximize communication speeds. The hero in the world of data is the optical fiber.

George Spagna, chair of the physics department at Randolph-Macon College, explains. Stars and planets form in the collapse of huge clouds of interstellar gas and dust. The material in these clouds is ...
