Feynman diagrams

Fans of particle physics often encounter a series of doodles called Feynman diagrams. These mystifying scribbles were invented by Richard Feynman and they encode information on how particle physics collisions unfold. But they have an even deeper significance. In this video, Fermilab’s Dr. Don Lincoln gives you a peek into the deeper meaning of these important scientific pictograms.
