Orbitals
by Jeff
Image text: And now someone drunk and hot stumbles in, one thing follows another, and the next roommate to return home sleeps in the hall lounge orbital.
This is a parody on the Pauli exclusion principle of quantum mechanics that states that no two identical fermions (electrons, protons, neutrons, muons) can occupy the same state. In the case of the comic, the state is the dorm room suite. The highest lowest level or state is in this comic is your own bedroom, then next two lower higher states are the next two bedrooms, and the lowest highest state is the couch in the living room. The image text goes on to speculate that the next lowest higher state would be the hall lounge if the living room itself was "occupied" by a romantic pair. The Pauli Sexclusion Principle dictates that no two roommates can occupy the same "state" in the case of sexual activity and it dictates the order of "states" .
The pun on the name is that when one person is barred from their room due to the sexual activity of their roomate, this is known as "sexclusion".
EDIT: Also, I'm not quite sure whether or not the drawings of the couples in the rooms are very crude stick figures...

Your highest/lowest designations are backwards compared to common terminology. The most favorable states would be the lowest, not the highest.
Also, I maintain that the image text should have included some spin-state/sex-position joke

Protons and neutrons are not fermions

Wrong! They are… sorry.

I wrote the below before you corrected! Thanks for correcting yourself. We appreciate it.

Sorry, Michael, no.

A fermion is any particle that has an odd half-integer (like 1/2, 3/2, and so forth) spin. Quarks and leptons, as well as most composite particles, like protons and neutrons, are fermions.

Fermions are particles which have half-integer spin and therefore are constrained by the Pauli exclusion principle. Particles with integer spin are called bosons. Fermions incude electrons, protons, neutrons.

Fermions act on each other by exchanging bosons. Examples include leptons (such as the electron), neutrons, protons and quarks.
