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 ...

I have always felt connected to the thermodynamic principle of entropy. I believed that my body at rest demonstrated the concept perfectly—and I now know that to be true, but not at all in the way ...

In this video, we explore the relationship between life and entropy, discussing how low entropy life can exist amidst increasing entropy as described by the second law of thermodynamics. We cover how ...
