The Standard Model: The Most Successful Scientific Theory Ever

The Standard Model of particle physics is the theory describing three of the four known fundamental forces in the universe, as well as classifying all known elementary particles. It is the most holistic and successful combination of years of scientific discovery ever combined into a single equation. In this explainer, Cambridge University physicist David Tong recreates the model, piece by piece, to provide some intuition into how the pinnacle of 400 years of science describes the fundamental building blocks of our universe and how they fit together. At the end of the video, he also points out what’s missing from the model and what work is left to do in order to complete the Theory of Everything.
