For two centuries, engineers have trusted a simple rule to predict how heat flows through solids, from jet-engine blades to smartphone chips. Now a set of carefully designed experiments has revealed a ...

Heat flows from hot to cold objects. When a hot and a cold body are in thermal contact, they exchange heat energy until they reach thermal equilibrium, with the hot body cooling down and the cold body ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat. Now a series of experiments at atomic and electronic scales is revealing ...

Anyone trying to circumvent the physical laws governing heat is going to get burned. A new experiment reveals how a device that robs a closed system of heat to make it more orderly, an action ...

— What is the zeroth law of thermodynamics? — What is the second law of thermodynamics? — What is the third law of thermodynamics? The first law of thermodynamics states that heat is a form of energy, ...

It’s a truism of science that concepts and inventions are rarely attributed to the person who actually came up with them. Most concepts and inventions have several creators, from the Pythagorean ...

To most physicists, the phrase “theory of everything” refers to a unified theory of nature’s fundamental interactions, the quest for which has kept researchers busy for the best part of a century.
