Research conducted at Lawrence Livermore National Laboratory (LLNL) is taking a closer look at entropy—the measure of internal energy per unit temperature that is unavailable for doing useful work—in ...

The production of entropy, which means increasing the degree of disorder in a system, is an inexorable tendency in the macroscopic world owing to the second law of thermodynamics. This makes the ...

A trapped cloud of ultracold atoms, colder than almost anything found in nature, has become the setting for a deceptively ...

A device based on a 155-year-old thought experiment has been realised at the largest scale yet, and it may help us understand how entropy, or disorder, is produced. It could also someday be used to ...

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 ...
