Feynman definition

The theory of Feynman path integrals in such theories is a further active area of research here at King's.

Probability amplitudes give probabilities when squared, and the rule for combining them was discovered by quantum physicist Richard Feynman.

These events are represented by a single vertex in a Feynman diagram.

I doubted that, as Feynman was precise in his usage of words.

Calculations in QED are carried out via " Feynman diagrams " which are successive approximations to QED.
