Why are protons so boring?
Neurons and electrons are mentioned a lot and are useful but last night I couldn't even remember the name of the proton.

yo where the fuck do protons and electrons get their charge from? what does charge even mean anyway?

>> No.12805415

>>12805413
The Noether current from the QED Lagrangian. Anything else you'd like to ask, faggot?

charge is a fundamental property of the elementary particles. so electrons are elementary particles and they have charge intrinsically; protons are not fundamental and get their charge from their constituent quarks.

the fact that elementary particles can have electric charge is related to the fact that nature has a local SU(2)xU(1) gauge symmetry, and electric charge emerges as the noether charge of this local symmetry via noether‘s theorem
