The Standard Model of Particle Physics

Warm up for this topic by breaking things into small bits.

  • everything is made of molecules

  • molecules are made of atoms

  • atoms are made of electrons and nuclei

  • nuclei are made of protons and neutrons

  • protons and neutrons are made of quarks As far as we know electrons and quarks are not made of anything smaller. We call them fundamental particles.

The standard model of particle physics describes how these and the other known fundamental particles quantum mechanically interact with each other.
