What do we learn from quantizing the relativistic point particle?

I will give a different perspective on the worldline formalism. Yes, the worldline formalism is perturbative, where the worldline proper time is the Schwinger proper time. However, once we use BRST ...

Average distance travelled by particle points placed uniformly at random in a sphere with speed $||v||$ and direction uniformly random?

This one, you just gotta break down to all the degrees-of-freedom, and slowly reject the trivial ones. There's too many to wing it. Also: when on/in the sphere, don't deal with polar angle, deal with ...

What do we learn from quantizing the relativistic point particle?

The theory of a relativistic point particle is insufficient for the same reason that the theory of a relativistic string is insufficient! Specifically, the former can compute the amplitude for a ...
