Quantum information theory explores the representation, transformation and transmission of information encoded in quantum systems. At its core lies the qubit, whose superposition and entanglement ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

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 ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

Entropy in an expanding universe / Steven Frautschi -- Growth of order in the universe / David Layzer -- Parity violation and the origin of biomolecular chirality / Dilip Kondepudi -- Kinetic theory ...

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 ...
