There are two big breakdown types: higher A Feynman diagram is a diagram that shows what happens when elementary particles collide.. Feynman diagrams are used in quantum mechanics.A Feynman diagram has lines in different shapes—straight, dotted, and squiggly—which meet up at points called vertices. 2010-02-14 · Let’s draw Feynman diagrams!

Physicists aren’t geniuses or anything, and they get distracted pretty easily. When you’re trying to calculate the probability of a particular particle interaction you’ll find yourself integrating over (adding up) every possible position and momentum of every involved particle. In order to visualize and describe quantum electrodynamical interactions, physicist Richard P. Feynman introduced an ingenious schematic form of drawing now called a Feynman diagram. In such a diagram, all particles are represented by lines, with straight lines representing fermions and wavy lines representing bosons (except for the Higgs boson, which is usually represented by a dashed line Feynman Diagrams.
