Two physicists at the University of Stuttgart have proven that the Carnot principle, a central law of thermodynamics, does ...
According to the researchers, Carnot determined the maximum efficiency of heat engines. He developed his principle, the ...
In the strange, often unintuitive world of quantum physics, one mystery has stood out for decades: Can quantum entanglement be manipulated in a reversible way, like energy in a perfect heat engine?
The original version of this story appeared in Quanta Magazine. In 1950 the Italian physicist Enrico Fermi was discussing the possibility of intelligent alien life with his colleagues. If alien ...
