Time series analysis forms an essential part of modern data science by examining sequential data to unravel the underlying dynamics of complex systems. In particular, entropy-based measures quantify ...

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: ...

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 ...

AS MUCH AS we may want to, we cannot go back in time. Is this just our current reality, or is the direction of time fixed by the laws of the universe? One clue to explain this “arrow” of time is the ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.
