Quantum Field Theory visualized
ScienceClic English builds quantum field theory from an empty universe upward, one ingredient at a time, until a blank spacetime turns into the Standard Model. The motive is honest and concrete: ordinary quantum mechanics cannot describe situations where particles appear and disappear, and it cannot explain why every electron in the cosmos is identical to every other. The fix is to stop treating particles as the fundamental things and treat the field as fundamental instead. Particles become disturbances in that field, the way ripples are disturbances on water.
