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.
