"Entropy is a measure of whether a system is in a special, very particular state, in which case the system has low entropy, or whether it is in one of many states that look more or less the same, in ...

Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can - if a proper definition of "entropy" is used. It is one of the most important laws of nature that we know: ...

Dr Peter Verheyen from the Sola Society examines whether quantum mechanics and information serve as the fundamental ...

What is the meaning of life? Even the best of us couldn't hope to answer that question in a Universe Today article. But there ...

Researchers taking the first-ever direct measurement of atom temperature in extremely hot materials inadvertently disproved a decades-old theory and upended our understanding of superheating. It's ...
