Feynman diagram

Feynman diagrams are like a type of cartoon drawing used by physicists to better understand how particles interact with each other. They use straight and curved lines to show how particles move and how different particles influence each other. For example, a straight line might represent a particle going in a straight line while a curved line might represent a particle that changes direction. Feynman diagrams also have symbols inside, which can help us understand how all the lines and particles interact.
