The two maths jokes that I can remember from my undergrad days are: "What's purple and commutes?" "An abelian grape" "What's yellow and equivalent to the axiom of choice?" "Zorn's Lemon" Evidently there's something inherently funny about group theory.

"What's yellow, normed, and complete?" "A Bananach space."

This actually has a bit of a point behind it, because the digits of Pi http://www.geom.uiuc.edu/~huberty/math5337/groupe/digits.htm... feature "999999" much earlier than would be expected if the digits were uniformly distributed. So once that sequence was discovered, it took a lot more work for mathematicians to convince themselves that it is completely "random" (or "normal" in the jargon). It still hasn't been proven though! https://en.wikipedia.org/wiki/Pi#Irrationality_and_normality

Mathematicians can have a focus (and corresponding lack of real-world awareness) that puts even us engineers to shame. Once as an undergrad I was taking a class in the math building, and there was a professor blocking the door because he was reading a flyer taped to it about an upcoming symposium or something. I coughed a little to indicate I was there, and he turned, acknowledged my presence, and then went right bac…

There's the classic/apocryphal story as well of the student who stops a math professor in the hallway and asks a complicated question. Professor gives a long, thorough answer, and the student becomes enlightened. Just as the student is about to leave, the professor asks "Wait, which way did I come from?" Student points out "That way", and the professor goes "Great, then I've had lunch."

Norbert Wiener, the MIT professor, is generally the source of many of these (probably somewhat apocryphal) stories of 'absent minded professors'.

tl;dr: They were down there talking about math one afternoon and the owner of the deli was trying to take the order from one of them and he was a little bit too preoccupied with mathematics to fully engage in the sandwich ordering process.

I think it's a little funnier than your tl;dr: in particular, a member of the math faculty, who has a sandwich named after him and who is friends with the owner, was a little bit too preoccupied with mathematics to fully engage with the sandwich ordering process.

My favorite math joke, imagine a professor speaking: "I explained it in my seminar, but they didn't seem to understand. So, I had to explain it again, and again they didn't get it. I ended up explaining it a third time, and by that point I understood it, but they still didn't understand.

I love math but I find this whole article and the associated jokes pretty contentless and somewhat boring.

I think it is one of those local situations where you have to know the people involved and go to the same cafe &c. In jokes basically.

"Let ε Or a similar but more blatant telling of the original joke would be "Let ℵ₀ be a group."

"Let ε<0." There goes the neighborhood!

Excellent. Thankyou very much.

I teach basic Maths to adults in the UK, so I tend to use these old faves...

"What did the zero say to the eight?"

"Nice belt"

(even my sister has heard that one)

"Why does noone talk to circles?"

"There's no point"

Thankyou and goodnight
