Exclusion Principle

Title text: Fermions are weird about each other in a standoffish way. Integer-spin particles are weird about each other in a 'stand uncomfortably close while talking' kind of way.

Explanation

This explanation may be incomplete or incorrect: Created by a SOCIALLY ANXIOUS ELECTRON - Someone who knows more about physics should explain this. Also, the title text needs explanation. Do NOT delete this tag too soon.

This comic is about the four fundamental forces of physics: gravity, electromagnetism, the strong force, and the weak force. In typical xkcd fashion, Randall also adds a joke entry, about how the interactions between electrons are different from how human interactions are, and they are therefore ‘weird’.

It also talks about the Pauli Exclusion Principle.

Transcript

[Inside the panel, there is an underlined header and a numbered list, with the fifth and last item in red:]

Fundamental Forces

1. Gravity

2. Electromagnetism

3. The Weak Interaction

4. The Strong Interaction

5. Electrons are weird about each other

[Caption below the panel:]

Big news: Physicists have finally given up trying to explain about the "exchange interaction" and agreed to just make the exclusion principle a force.

Is this out of date? .
