Aircraft engines work better at higher temperatures. As they get hotter, they burn fuel more efficiently, which means they can fly farther on the same volume of propellant. But they can’t get too hot ...

FROM time to time controversies have appeared in various journals regarding that most difficult of all physical conceptions—entropy. I have purposely avoided passing any opinions as to the merits of ...

I recently led a webinar on the laws of thermodynamics, which got me thinking: A business is very much a closed system, such as a universe. Therefore, if entropy is always increasing in a closed ...

Looking back a variety of distances corresponds to a variety of times since the Big Bang. Entropy has always increased from any moment to the next, but that doesn't mean that the Big Bang began with ...

In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of thermodynamics, which states that entropy remains positive and vanishes at ...
