Elementary Particles and Forces

The video provides an overview of particle physics, starting with the periodic table and atomic theory. It explains the discovery of electrons, protons, neutrons, and quarks, leading to the standard model of particle physics. The video discusses fundamental forces and the concept of particles as fields. It highlights the Higgs mechanism's role in giving mass to particles, emphasizing its importance in the standard model.
