Particle Physics

Particle Accelerators

Particle accelerators speed particles to near light-speed and smash them together. The collisions reveal fundamental physics.

Lagrangian Formalism

Discover Lagrangian Formalism as a core part of Particle Physics. This lesson explains what it means, walks through a real example, introduces key terms, and includes three hands-on activities to help you understand and apply the idea.

Quarks and Hadrons

Protons and neutrons are made of quarks. Three quarks per proton/neutron. They are held together by the strong force.

Gauge Symmetries

Discover Gauge Symmetries as a core part of Particle Physics. This lesson explains what it means, walks through a real example, introduces key terms, and includes three hands-on activities to help you understand and apply the idea.

Neutrino Mass Puzzle

Discover Neutrino Mass Puzzle as a core part of Particle Physics. This lesson explains what it means, walks through a real example, introduces key terms, and includes three hands-on activities to help you understand and apply the idea.

Silicon Trackers: How Particle Detectors Map Invisible Collisions

Discover Silicon Trackers as a core part of Particle Physics. This lesson explains what it means, walks through a real example, introduces key terms, and includes three hands-on activities to help you understand and apply the idea.
