"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 ...

For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

Gravity is the most familiar of nature’s forces. It keeps our feet planted on the ground and dictates the movements of planets and stars. Yet, even so, gravity remains one of the greatest mysteries in ...

This is a preview. Log in through your library . Abstract We outline a new lower bound on graph entropy and discuss some of its applications. In particular, our results allow us to calculate the graph ...

Electron–proton collisions Study reveals importance of entanglement entropy. (Courtesy: Kevin Coughlin/Brookhaven National Laboratory) An international team of physicists has used the principle of ...

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: ...
