Hi,
I have difficulty comprehending Feynman diagrams. Although I’m a high schooler, could you please explain to me like I’m five as to what exactly a FD *shows* and what it’s used for? Thanks.
In: Physics
They *show* interactions between fundamental particles. There are a few rules about what these particles can do in the diagram, and by analyzing a Feynman diagram, you can determine if the interaction is possible and other complex things that are used in conjunction with highly complex mathematics.
In all, they allow for a pictorial representation of quantum interactions, then you can make predictions about what kinds of composite particles are possible, and what they might do.
