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 strange behavior of atoms and photons. Physicists have long suspected that ...

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 ...

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

A satellite image shows the huge snowstorm that blanketed the northeastern United States this week. The blizzard was an example of how storms are getting less common but more intense.

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 ...
