LECTURE 41
questions before lecture
think about these
- What is a boson? a fermion?
- What is a gauge? Think of a tire gauge, a rain gauge, and a temperature gauge (thermometer). What do they have in common?
- What virtual particle have we studied so far which is the internal line in a Feynman diagram?
- What is the spin of a photon?
- Name the four forces (interactions). What is something you know about each one, for example the property which gives rise to it and feels it, or the strength of its coupling?
