Philip Ball looks at how a little-known paper by Niels Bohr demonstrates the turmoil in physics on the brink of quantum ...

A new theoretical approach is proposed to explain the nature of the well-known narrow and intense optical J-band of ...

This model was a centrepiece of what has become known as the old quantum theory, which itself was the product of a realization at the turn of the twentieth century that the precepts of classical ...

Armed with modern quantum theory, I began to uncover a new quantum dimension to life itself. A century-old mystery revisited In the 1920s, Gurwitsch's experiments revealed a startling phenomenon.

The universe is getting more disordered, entropy is growing -- this is the second law of thermodynamics. But according to quantum theory, entropy should actually stay the same. Scientists took a ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...

Devised in 1935 by the Austrian physicist Erwin Schrödinger, this thought experiment was designed to shine a spotlight on the difficulty with interpreting quantum theory. Quantum theory is very ...
