I'm trying to come up with a good math joke for our math team t-shirts. Last year we had "Know you limits, don't drink and derive." The shirt included a fuzzy graph.

I'm thinking about using an xkcd comic if the author gives me permission, but the images are somewhat small for t-shirts, so I might have to throw my own together anyways.

Got any good ideas?

TamDenholm• 16 years ago

Why did the chicken cross the Möbius strip?

To get to the same side.

troymc4• 16 years ago

This joke might be funnier if the answer is:

To get to the other side.

(The mathematicians will know that the chicken's quest will fail. Then they'll feel sorry for the chicken...)

zck• 16 years ago

An engineer, a physicist, and a mathematician go to a conference together, and split a room in the hotel. They check in and go to sleep. The hotel is old (they couldn't afford anything better on professors' salaries), so the room is heated by a fireplace. A spark jumps out of the fire and catches the rug on fire. The engineer smells the smoke and wakes up. He jumps out of bed, sees the fire, and looks around. The first thing he sees is the ice bucket, so he takes it, fills it up from the sink, and throws the water on the fire. He drops the ice bucket next to the fireplace and goes back to bed.

The fire throws another spark, creating another fire. The physicist wakes up and sees the fire. He calculates that, given the size of the fire, and amount of oxygen needed to be displaced to put out a fire of said size, a glass of water will be sufficient. He fills up his water glass from the sink, and while running to the fire, throws the water at the fire at the exact distance from the fire that gets the water to the fire earliest, putting it out. He drops the glass next to the fireplace and goes to sleep.

The fire sparks once more, and the mathematician wakes up and sees the fire. He looks at the ice bucket and glass sitting next to the fireplace, says "Aha! A solution exists!", and goes back to bed.

It's a math joke, but not one suitable for t-shirts.

JeanPierre• 16 years ago

While we're at jokes not suitable for t-shirts:

A mathematician, an engineer and a physicist were travelling through Scotland when they saw a black sheep through the window of the train.

"Aha", says the engineer, "I see that Scottish sheep are black."

"Hmm", says the physician, "You mean that some Scottish sheep are black".

"Nonono", says the mathematician, "All we know is that there is at least one sheep in Scotland, and that at least one side of that one sheep is black."

Surprised this isn't already here, pretty popular at my college:

I wish I was your derivative, so I could lie tangent to your curves.

sliverstorm• 16 years ago

And the companion bio-joke:

I wish I was mRNA polymerase, so I could unzip your genes.

Tichy• 16 years ago

Wow, best pickup line I've ever heard :-)

possibilistic• 16 years ago

I've never heard them called "mRNA polymerases." RNA polymerase should do just fine.

In fact, wouldn't helicase do better?

joshzayin• 16 years ago

Helicase is what unzips the genes, not RNA polymerase. RNA polymerase allows transcription (or creation of an mRNA molecule complementary to the given gene) to take place.

waterhouse4• 16 years ago

That one is so bad, because it doesn't work. Presumably the derivative is used to calculate a tangent line. However, a tangent line touches the curve only at one point, unless the curve is totally flat. Either way, this is not what you want. You want fuckin' Taylor series approximations. (They won't work on curves that aren't smooth, but that's all right, because those are the curves you want to touch anyway.)

Aww yeah.

drbaskin• 16 years ago

Strictly speaking, the Taylor series won't even do what you're wanting them to do for smooth functions. (Consider the function e^{-1/x^2}, whose Taylor series is zero at the origin. In fact, given any sequence of numbers, you can cook up a smooth function which has that sequence as the coefficients of its Taylor series at zero.) If you want the Taylor series to agree with the function in an entire neighborhood of a point, you want the function to be real (or complex) analytic (at least in a neighborhood of that point).

This is by far the best t-shirt candidate.

troymc4• 16 years ago

xkcd comics are already licensed under a Creative Commons Attribution-Noncommercial 2.5 license. That's probably all you need for a math team t-shirt.

younata• 16 years ago

upvoted it (at this time, it cancelled out a downvote).

No idea why it was initially downvoted, it's good information to point out. So long as you don't make money off the shirts, it's ok to use xkcd comics.

whackedspinach• 16 years ago

I saw that, but in the end some of the images are only about 700x400 px. At 200 ppi (which is what t shirts should be printed at, I guess), that just isn't a high enough resolution. And I'm not sure If I really want to make it larger since it will not look all that good.

twymer3• 16 years ago

You could always try contacting Randall and explain what you'd like to use the particular strip for to see if you could get a larger image.

Even if the current size was large enough, he would probably appreciate knowing about his work being printed like that as most people do.

troymc4• 16 years ago

You could load an xkcd comic into Inkscape or another vector graphics editor and trace it out by hand. It wouldn't take that long, and the end result would be a vector graphic that you could render to whatever size or resolution you need. (Creating a derivative work like this is allowed by the license.)

Or its sibling: a genie grants both a mathematician and an engineer their greatest desire to be located at the end of the room given that each step they take towards it is half the distance than their last.

If you want to incorporate ideas from xkcd without using any of the published comics, you could come up with your own nerd snipe and put it on the front of your shirt. Then put something on the back like "You've been nerd-sniped!"

Make sure to hang out near busy streets and train tracks when you wear it.

Below is my favorite math joke (copied it from http://www.onlinemathlearning.com/math-jokes-calculus.html as I didn't remember the exact wording). It's a bit long for a T-shirt, but a simple comic strip version could be made.

A constant function and e^x are walking on Broadway. Then suddenly the constant function sees a differential operator approaching and runs away. So e^x follows him and asks why the hurry. "Well, you see, there's this differential operator coming this way, and when we meet, he'll differentiate me and nothing will be left of me...!" "Ah," says ex, "he won't bother ME, I'm e to the x!" and he walks on. Of course he meets the differential operator after a short distance.

e^x: "Hi, I'm e^x"

waterhouse4• 16 years ago

In the fall of 2009, Mr. Apollinax discovered a method of simplifying mathematical expressions with profound, wide-ranging consequences. Mr. Apollinax has given it the name "indiscriminate cancellation". We see its power and reliability here:

  16/64 = 1/4 ;Cancel the 6
  19/95 = 1/5 ;Cancel the 9
  26/65 = 2/5 ;Cancel the 6
  49/98 = 4/8 ;Cancel the 9

Using his new tool, Mr. Apollinax quickly discovered and prove several surprising theorems, including the following:

  sin x / n = six ;Cancel the n

But the most celebrated application of this method of Mr. Apollinax is his amazing discovery of a deep, unexpected connection between the theories of complex numbers and trigonometry and the preparation of Mexican cuisine:

  sin / cos = tan ;definition of tangent
  i / co = ta ;cancel n and s
  i = taco ;multiply both sides by co

[Martin Gardner wrote a couple of April 1st columns about Mr. Apollinax. Worth checking out. Also, it's kind of a cool computer science problem to find number pairs like 16/64. I'll mention that if we generalize it to "abcd...x / bcd...xy = a/y", then there are seven nontrivial (where a,b,c,etc. aren't all the same digit) 3-digit pairs, including 484/847.]

The mathematician shakes his head sadly and says "There is at least one cow in this county that is black on at least one side".

Q: Why do Jewish mathematicians prefer complex analysis over many other fields of mathematics? A: because it is Cauchy'er.

I was never able to get this one to work out, but maybe someone smarter can do it. There was a line in a physics book I read once that said something like "electromagnetic fields can be described by anti-symmetric tensors of the second bank in four dimensions". I tried to set up a story involving Jewish industrialists who were elected to public office, and who owned farms, being attacked by a bunch of jew-hating males from a local choir, who also happened to work for the a small local bank, who had their farms surrounded and did coordinated attacks from North, South, East and West. The punch line was to be something "elected magnate's fields were defiled by anti-semitic tenors from the Second Bank in four directions". But I never could come up with a story that would end with that, and would bring to mind the corresponding physics so as to make that a groan-worth pun.

Years ago, three friends from Poland decided to visit relatives in the US they had not seen for decades. Since this was a once-in-a-lifetime trip, they did in grand style, on the Concorde.

Of course, there was trouble on the flight and of course the flight attendants asked if any of the passengers had experience with aircraft, and of course one of our friends did.

Not short enough for a shirt probably, but still good:

Three mathematicians and three accountants are traveling by train to a conference. At the station, the three accountants each buy tickets and watch as the three mathematicians buy only a single ticket.

"How are three people going to travel on only one ticket?" asks an accountant. "Watch and you'll see," answers an mathematician. They all board the train. The accountants take their respective seats but all three mathematicians cram into a restroom and close the door behind them.

Shortly after the train has departed, the conductor comes around collecting tickets. He knocks on the restroom door and says, "Ticket, please." The door opens just a crack and a single arm emerges with a ticket in hand. The conductor takes it and moves on.

The accountants saw this and agreed it was quite a clever idea. So after the conference, the accountants decide to copy the mathematicians on the return trip and save some money (being clever with money, and all). When they get to the station they buy a single ticket for the return trip.

To their astonishment, the mathematicians don't buy a ticket at all. "How are you going to travel without a ticket?" asked one perplexed accountant.

"Watch and you'll see," answered an mathematician. When they board the train the three accountants cram into a restroom and the three mathematicians cram into another one nearby. The train departs.

Shortly afterward, one of the mathematicians leaves his restroom and walks over to the restroom where the accountants are hiding. He knocks on the door and says, "Ticket, please."

An evil dictator locks up all the academics in his country in a time of war. As the war worsens the army platoon left guarding the detention facility is called away to the front, and leaves the academics unattended in their cells bottled water, canned food and no can openers. When the war is over and the dictatorship is collapsed, the detention facility is opened up. It's found that most of the humanities and social scientists have survived, having opened their cans by throwing them randomly at the walls until the cans broke open. The physicists had figured out the optimum angle at which to throw the can in order to reliably open it. Several mathematicians have suffered severe malnutrition, having successfully proven that "there exists a unique optimal throwing angle theta ..." The cell of a topologist was found empty, though a muffled screaming could be heard from one of his cans. A can opener is fetched, and the topologist is removed, covered in food, mumbling about an error in sign.

Maybe you could fit just the punchline on a T-shirt:

A sociologist, a physicist, and a mathematician are given 100 ft of fence and asked to enclose the greatest area.

-The sociologist makes a square. -The physicist makes a circle and says he can PROVE it's the best answer. Take that, mathematician! -The mathematician knocks off all but a few fence-links, wraps the fence around himself, and says "Define the outside of the fence to be the ground which contains me..."

(Say the punchline in a smarmy, nasal voice.)
