A challenge in materials design is that in both natural and humanmade materials, volume sometimes decreases, or increases, with increasing temperature. While there are mechanical explanations for this ...

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 ...

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 ...

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 ...

Scientists have shown, through probabilistic calculations, that there is indeed, as had been hypothesized, a rule of 'entropy' for the phenomenon of quantum entanglement. This finding could help drive ...

Entropy estimation and information theory form the bedrock of our understanding of uncertainty and complexity in both natural and engineered systems. At its core, entropy quantifies the ...
