"In the past, entropy was lower; the future is where entropy is higher." However, quantum physics encounters a problem here: the mathematician and physicist John von Neumann was able to show: ...

Could our universe be expanding then shrinking back into a tiny point, reliving a kind of big bang over and over again? Probably not, according to a mathematical analysis that argues that the laws of ...

It is one of the most important laws of nature that we know: The famous second law of thermodynamics says that the world gets ...

Technological devices are getting ever smaller, but as they approach the scale at which quantum physics matters, our understanding of how they interact with their environment evaporates. James Millen ...

Researchers at Tampere University and their collaborators from Germany and India have experimentally confirmed that angular momentum is conserved when a single photon is converted into a ...

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: ...
