Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold ...
In a recent paper, SFI Professor David Wolpert, SFI Fractal Faculty member Carlo Rovelli, and physicist Jordan Scharnhorst ...
"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 ...
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 ...
In spite of their simple description in terms of rotations or symplectic transformations in phase space, quadratic Hamiltonians such as those modelling the most common Gaussian operations on bosonic ...
To many physicists, “Tsallis entropy” has been a revolution in statistical mechanics. To others, it is merely a useful fitting technique. Jon Cartwright tries to make sense of this world of disorder. ...
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, ...
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: ...
