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: ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

Entropy is the process of losing energy and this can apply to physics and social systems alike. JamesBrey/iStock via Getty Images Life is full of small decisions: Should I pick up that sock on the ...

Gravity is usually presented as the most familiar of nature’s forces, the quiet background pull that keeps feet on sidewalks and planets in orbit. A growing group of physicists is now treating that ...

We have been taught to think of entropy as a bad thing. "Things fall apart; the centre cannot hold;/Mere anarchy is loosed upon the world," wrote William Butler Yeats in the aftermath of World War I, ...

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 ...

Entanglement is one of the most intriguing features of quantum mechanics. It describes non-local correlations between quantum objects, and is at the heart of quantum information sciences. Entanglement ...

In my last report from Physics@FOM, I will talk about something I am truly not competent to discuss: "Holography, ADS/CFT and the emergence of gravity." I realize that I am not always the sharpest ...

Cities may be the defining element of human civilization. The path from hunter-gatherers in the Paleolithic era 25,000 years ago to the high-tech, high-wonder jumble we inhabit today runs straight ...
