Feynman diagrams revolutionized theoretical physics
Feynman diagrams are a pictorial representation of mathematical expressions describing particle interactions. They simplify complex calculations in quantum field theory. David Kaiser notes their increasing use since the mid-20th century.
Example
A Feynman diagram representing electron-electron scattering shows two incoming electrons, an intermediate photon, and two outgoing electrons.
Remember this
Feynman diagrams make abstract particle physics calculations more accessible.
