Things I want to communicate in this chapter

we normally think of two types of particles: fermions and bosons.
The reason for this is exchangeability
Exchangeability can be defined using path-uniqueness
Path-uniqueness can be defined topologically or geometrically
Topologically it’s a bit easier, so we tend to do that

Comments on Anyons

Make a note: [[Explaining away the anyons using geometry is kind of the same as explaining away phase transitions: you can do it but you lose universality]]
Flip the order of III: first introduce Shech’s point, then go through the FQHE, see “huh, kinda cringe”, then go through the topological stuff.
Make an animation making it plausible that “paths being the same” = “homotopy”
