British theoretical physicist Paul Dirac was one of the most significant figures in the early days of quantum physics, who along with Erwin Schrödinger won the Nobel Prize for physics in 1933. But it ...

The Dirac equation is monumental in physics, encapsulating so beautifully, in relativistic terms, the behaviour of a spinning electron, or indeed of any particle that has half-integer spin (Milestone ...

An international group of physicists has traced the origin of an electromagnetic interaction to the Dirac equation, a fundamental equation of quantum physics. The interaction couples the spin of the ...

The internet is stuffed with online quizzes and surveys, ranging from which "Friends" character you are to who you're about to vote for. But the BBC recently asked something more profound of its ...
