One of the most fundamental rules of physics, the second law of thermodynamics, has for the first time been shown not to hold for microscopic systems. The demonstration, by chemical physicists in ...

Behind the veil: A black hole's event horizon contains an infinite number of microstates, but expressing these microstates in terms of a finite set of representative quantum superpositions makes it ...
