The famous second law of thermodynamics says that the world gets more and more disordered when random chance is at play. Or, ...

An international collaboration led by Nagoya University in Japan sheds new light on the relationship between quantum theory ...

New research shows that the second law of thermodynamics, which states entropy increases over time, also applies to closed ...

For over a century, the Maxwell’s Demon paradox has haunted physics. This thought experiment suggests that a tiny, ...

If you define the concept of entropy in a way that it compatible with the basic ideas of quantum physics, then there is no longer any contradiction between quantum physics and thermodynamics.

The grandfather paradox is just one of the thorny logical problems that arise with the concept of time travel. But one physicist says he has resolved them.

Entropy always increases, but in quantum systems, traditional entropy measures seem constant. TU Wien researchers resolved this paradox by considering Shannon entropy, which accounts for the ...

The second law of thermodynamics demands that the entropy of any closed macroscopic system should never decrease. The laws of physics naturally drive systems towards states of increasing disorder ...

Vanderbilt University physicist Lorenzo Gavassino isn't so sure this is as big an obstacle as time-traveler pessimists have ...
