Solving the Impossible in Quantum Field Theory

Season 3 Episode 9 | 11m 52s | Video has closed captioning.

The equations of quantum field theory allow us to calculate the behaviour of subatomic particles by expressing them as vibrations in quantum fields. But even the most elegant and complete formulations of quantum physics – like the Dirac equation or Feynman’s path integral - become impossibly complicated when we try to use them on anything but the most simple systems.
