A new analysis of the “Boltzmann brain” paradox suggests our memories and sense of reality could, in theory, be random ...

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: ...

It is one of the most important laws of nature that we know: The famous second law of thermodynamics says that the world gets more and more disordered when random chance is at play. Or, to put it more ...

Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. Physics teachers designed a hand-held model to demonstrate the ...

Entropy. The word itself should cause insomnia. It means that matter and energy will degrade—ultimately leading to chaos in the universe—if things are left alone. So why is a new theory suggesting ...

The fundamental laws of physics insist that no patterns can permanently survive nature’s steady course towards disorder – or can they? A new proof offers a peculiar counterexample to the once-settled ...

A team of researchers from King’s College and Imperial College London have proposed a new way to calculate entropy production in active matter systems Bacteria use chemical energy, usually from ATP or ...

Figure 1. Quantum entanglement entropy and quantum materialsA quantum system with subsystem A and its compliment B. For a quantum state, particles in subsystem A are entangled with particles in ...
