The physics of thermodynamics, which involves quantities like heat and entropy, offers well-established tools for determining how far from equilibrium an idealised system of particles is. But when it ...

Bone density refers to how much calcium and other minerals make up your bones. When your bones have more minerals, they have a higher bone density, meaning they're stronger and less likely to break.

USC engineers have developed an optical system that routes light autonomously using thermodynamic principles. Rather than relying on switches, light organizes itself much like particles in a gas ...
