And translating from their arcane vocabulary:
  • Prelims: first year undergrad
  • Honour school; other years of undergrad, sometimes it includes masters others not which is confusing
  • MPhil, MSc, MSt: masters

The name actually comes from "any". Amazing.
Can only exist in 2D surfaces, not 3D, where fermions and bosons are the only options.
All known anyons are quasiparticles.

Why do multiple electrons occupy the same orbital if electrons repel each other? Updated +Created
That is, two electrons per atomic orbital, each with a different spin.
As shown at Schrödinger equation solution for the helium atom, they do repel each other, and that affects their measurable energy.
However, this energy is still lower than going up to the next orbital. TODO numbers.
This changes however at higher orbitals, notably as approximately described by the aufbau principle.
Aufbau principle Updated +Created
Boring rule that says that less energetic atomic orbitals are filled first.
Much more interesting is actually determining that order, which the Madelung energy ordering rule is a reasonable approximation to.
