Quarks, hadrons, baryons, leptons - we explore the material particles, ponder the question of why the electron has two heavier cousins, and describe the snark of Wolfgang Pauli in this - our second episode in a series explaining fundamental subatomic and atomic physics, and the Standard Model. Can you tell your quarks from your elbow? If not, never fear, because these episodes will be your guide to particle physics, and, specifically, what’s called the Standard Model. Has absolutely nothing to do with the catwalk, but instead the fundamental building blocks that make up all of visible matter and energy in the Universe.
