Light does not “think” in any human sense. Still, under the right conditions, it can behave in a way that looks uncannily like a memory system.

Many physicists are searching for a triplet superconductor. Indeed, we could all do with one, although we may not know it yet ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in probabilities and the other in smooth curves of spacetime. A new line of work argues ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

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 ...
