Understand the principles of rigid body equilibrium and torque. Learn how forces and rotations balance in physical systems.

Two physicists have offered a way to mathematically describe a particular physics phenomenon called a phase transition in a system out of equilibrium. Such phenomena are central in physics, and ...

Living systems are constantly being driven out of equilibrium by consuming energy. Studying fluctuations can tell us how they do so while maintaining order — and what this teaches us about ...
