When French engineer Sadi Carnot calculated the maximum efficiency of a heat engine in 1824, he had no idea what heat was. In those days, physicists thought heat was a fluid called caloric. But Carnot ...

The first law of thermodynamics is undergoing a huge renovation. A team lead by researchers at West Virginia University released a paper detailing how the fundamental law can be applied more broadly ...

The laws of thermodynamics are pretty straightforward: Normally, heat from a hot object will flow to a cold one until they reach the same temperature, bringing the system to a state of equilibrium.

The young field of quantum thermodynamics, which tries to reconcile quantum theory with the 200-year-old science of heat and entropy, is booming. It’s also causing some heated disputes. Many ...

Thermodynamics is the study of heat and energy. At its heart are laws that describe how energy moves around within a system, whether an atom, a hurricane or a black hole. The first law describes how ...
