Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. A new equation sheds new light on how entropy is produced on a very short time scale in laser ...

Today’s most advanced clocks keep time with an incredibly precise rhythm. But a new experiment suggests that clocks’ precision comes at a price: entropy. Entropy, or disorder, is created each time a ...

For all its tumult — erupting stars, colliding galaxies, collapsing black holes — the cosmos is a surprisingly orderly place. Theoretical calculations have long shown that the entropy of the universe ...

Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lami from the University of Amsterdam have shown, through probabilistic calculations, that there is indeed, as had been ...

From a laptop warming a knee to a supercomputer heating a room, the fact that computers generate heat is familiar to everyone. But theoretical physicists have discovered something astonishing: not ...

I had so much fun writing about entropy last month that I just couldn’t stop! To catch you up on our sojourn through one of the most important but misunderstood ideas in science, here is a quick ...
