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 ...
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 ...
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 ...
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 ...
In my last report from Physics@FOM, I will talk about something I am truly not competent to discuss: “Holography, ADS/CFT and the emergence of gravity.” I realize that I am not always the sharpest ...
In 1961 Rolf Landauer linked information and thermodynamic entropy by showing that erasing or combining bits of memory must be accompanied by an increase in entropy. For the first time since then, a ...
Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...
What’s the price of an accurate clock? Entropy, a new study has revealed. Entropy — or disorder — is created every time a clock ticks. Now scientists working with a tiny clock have proven a simple ...
