The ‘quantum’ principle that says why atoms are as they are
It was a product of what is now labelled the old quantum theory — a period of ad hoc theorizing between 1900 and 1925 that led to the introduction of a consistent theory of quantum mechanics in ...

Quantum physics, a century old, still passes understanding
The size of a quantum is indicated by a tiny number h, now known as Planck’s constant. [ The search for ‘stringy physics’, a unified theory that goes beyond quantum mechanics and general ...
Distinguishing classical from quantum gravity through measurable stochastic fluctuations
In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature.

Radical theory unites gravity, spacetime, and the quantum realm
Physicists have proposed a radical approach that questions decades of belief about how gravity, spacetime, and quantum mechanics fit together.

String theory
It’s the only one of the four fundamental forces of nature described by general relativity, and the only one that quantum theory cannot address. Coming up with a model that ties up all four ...
