Episode 100: Unsolved Problems in Science

We conclude our series on the standard model with an introduction to gauge theory. We discuss how the requirement of local gauge invariance generates interaction terms in the Lagrangian, and introduce the U(1) x SU(2) x SU(3) group structure of the standard model. We also conside ...  Show more

An introduction to the particles and forces that constitute the standard model of particle physics. After some historical background, we introduce each of the three fundamental forces that comprise the standard model - electromagnetism, the strong nuclear force, and the weak nucl ...  Show more
