In one of my mathematics classes, the professor noted (and freely admitted that the joke was not original with him), "There are essentially two groups of mathematicians: Those that have read Weyl and those that have not. And once you enter the first group, you will never be understood by anyone in the second group."

I guess it's only funny to mathematicians.

Once you enter the first group, you are stuck there. This phenomenon is known as the "Weyl loop."

Niiiice. -Raymond]If you end up in a "Weyl loop" and get tired, probably the best thing for yourself and your family, is to take a break.

Break? Why not Das Continue-um? Get it? Like Weyl's Das Kontinuum? It's funny, right?

So is not-so-funny-math-joke time? Okay!

Math class for Introduction in Algebra (propositional logic) learning about tautology, the professor tell:

"So a nervous mathematician called a friend from maternity to tell that his baby was born.

-Hey! I am a father now! -saids the mathematician

-Cool! Congratulations! It's a boy or a girl? -asked the friend

-YES!

Note: She said that only she found it funny before telling it.

My self, and only Me, laugh. Is that good or bad? YES!

One quote about Weyl I'll always remember reading is: "Apart from agreeing with reality it is certainly a magnificent achievement of pure thought. – Einstein, to Hermann Weyl, about Weyl's attempt to unify gravity and electromagnetism." (copied from the footnote at math.ucr.edu/…/week246.html)

What's yellow and equivalent to the axiom of choice? Zorn's Lemon.

What's purple and commutative? An Abelian grape.

Why is a PhD theologian like the Laplacian operator acting on a scalar field?

They're both div grad!

…

Cause, you know… Divination graduate…

*crickets*

I myself prefer some nice Abelian soup.

And remember kids: Don't drink and derive!
