....... is famous for having proposed the "color charge" of quantum chromodynamics, for having done early work on spontaneous symmetry breaking in physics, and for having discovered that the dual resonance model could be explained as a quantum mechanical theory of strings. He is accounted as one of the founders of string theory.

Ok then! How long, is, a piece, of ,String?

Quantum mechanics allows matter to behave as both particles and waves. Quantum objects can be in different states at the same time, and can sometimes seem to be in two places at once.
Alan describes how this was demonstrated in a simple experiment using a laser and a special camera. A single wave of light, a photon, passes through two slits at the same time and creates an interference pattern.
---------------------------------------------------------------
"A photon... can't be split," says Alan "but it's clearly in two places at the same time which is very exciting".
"I didn't understand that whole side of physics," he says.
"The principle that light can be in two places at the same time is absolutely extraordinary"
