A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

One of the great successes of 20th-century physics was the quantum mechanical description of solids. This allowed scientists ...

Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

Quantum particles have a social life, of a sort. They interact and form relationships with each other, and one of the most important features of a quantum particle is whether it is an introvert—a ...

Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts ...
