Fundamentals of Particle Physics

The video tutorial covers the classification of particles in AQA A-level physics, focusing on fermions and bosons. Fermions include hadrons and leptons, with hadrons experiencing the strong nuclear force. The video explains quantum numbers and conservation laws, such as baryon and lepton numbers. It also discusses muon decay and the properties of strange particles, highlighting the conservation of strangeness during production and its non-conservation during decay.
