Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

Quantum thermodynamics explores the fundamental principles governing energy conversion at the smallest scales, where quantum effects such as coherence and entanglement significantly influence the ...

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 ...

For more than a century, thermodynamics has described how heat flows and engines run, while quantum mechanics has ruled the ...

In real life, laws are broken all the time. Besides your everyday criminals, there are scammers and fraudsters, politicians and mobsters, corporations and nations that regard laws as suggestions ...

A heat engine is a device that accepts heat from a high temperature reservoir, T H , performs externalwork, W, and rejects heat to a low temperature reservoir T L. The diagram shows a practical ...

Hot stuff: The experimental set-up with the trapped calcium. (Courtesy: Johannes Roßnagel) Physicists in Germany have taken mechanical miniaturization to the ultimate limit by producing a heat ...

A recent study led by Chinese scientists has challenged the hundreds-of-year-old myth that a heat engine can achieve both ...

THIS is a very good specimen of that sort of book which is an amplification of the lecture notes of a professor who has carefully prepared problems for students. We may not always like the way in ...
