In 1813, Napoleon's failed campaign against Russia led to a coup d'état in Paris, France. Prussia and Austria then invaded France. Among the troops guarding Paris at the time was Sadie Carnot.

One famous limit of thermodynamics is that heat engines, like steam engines and internal combustion engines, must be less efficient than a Carnot heat engine (a heat engine cycle designed by French ...

In 1824, French engineer Nicolas Leonard Sadi Carnot – known as the father of thermodynamics – proposed what is known as the Carnot engine, the most efficient engine which is theoretically possible.

THE cycle proposed by Dr. J. S. Haldane (NATURE, August 29, p. 326) as a standard of comparison for steam engine performance can be shown quite readily on a temperature-entropy chart, and thus be ...

One of the greatest inventions is the steam engine. But why? One of the greatest inventions is the steam engine. But why? What makes it so useful? And how does it work? In this episode of Crash Course ...

In a recent study published in Nature Physics, ICFO researchers Ignacio Martínez, Édgar Roldán, the late Dmitri Petrov and Raúl Rica, in collaboration with the Universidad Complutense de Madrid, have ...

A British engine manufacturing start-up is taking inspiration from a 200 year-old principle of thermodynamics to achieve a significant breakthrough in engine technology, one which promises a ...

ON p. 326 of NATURE for August 29 appears an abstract of a paper by Dr. J. S. Haldane, which he read before the Institution of Mining Engineers on June 16. In this paper he has “thrown to the winds” ...
