Efficiency asymmetry: Scientists report fundamental asymmetry between heating and cooling

A new study led by scientists from Spain and Germany has found a fundamental asymmetry showing that heating is consistently faster than cooling, challenging conventional expectations and introducing the concept of "thermal ...

Physicists identify overlooked uncertainty in real-world experiments

The equations that describe physical systems often assume that measurable features of the system—temperature or chemical potential, for example—can be known exactly. But the real world is messier than that, and uncertainty ...

Entropy could be key to a planet's habitability

We all know that to have life on a world, you need three critical items: water, warmth, and food. Now add to that a factor called "entropy." It plays a role in determining if a given planet can sustain and grow complex life.
