Exams and such.

Yeah, so exams.

They're a thing I do.

That I need to focus on.

Instead of playing ponies.

So yeah.

I'll return.

But for now, don't expect swift replies.

You shall be missed, Intel!

Why not play ponies in your exams?

Seriously though, good luck, see you soon!

When particles are indistinguishable, the combined wave function must be expressed as Y(x1,x2)=A(Ya(x1)Yb(x2)(+/-)Yb(x2)Ya(x1)), where A is the normalising constant. If the function is additive, it describes a boson, otherwise it describes a fermion.

Fermions cannot occupy the same place because of the Pauli Exclusion Principle; Y(x1,x1)=A(Ya(x1)Yb(x)-Yb(x1)Ya(x1))=0. Bosons can. Bosons also have integer spin, whilst Fermions have half integer spins, this means electrons are fermions with spin=1/2. It is through this phenomena that electron shells form.

Now that's over and done with, let's play ponies, watch Mad Max, then play ponies.

Welcome Back!! Now let's play Mystery Twins Ponies!

I'll take my Vet Tech classes over that mess up there.. Board Exam in a month. Woot.
