Dean, to the physics department. “Why do I always have to give you
guys so much money, for laboratories and expensive equipment and
stuff. Why couldn’t you be like the maths department – all they need
is money for pencils, paper and waste-paper baskets. Or even better,
like the philosophy department. All they need are pencils and paper.”

A somewhat advanced society has figured how to package basic knowledge
in pill form.
A student, needing some learning, goes to the pharmacy and asks what
kind of knowledge pills are available. The pharmacist says “Here’s a
pill for English literature.” The student takes the pill and swallows
it and has new knowledge about English literature!
“What else do you have?” asks the student.
“Well, I have pills for art history, biology, and world history,”
replies the pharmacist.
The student asks for these, and swallows them and has new knowledge
about those subjects.
Then the student asks, “Do you have a pill for maths?”
The pharmacist says “Wait just a moment”, and goes back into the
storeroom and brings back a whopper of a pill and plunks it on the
counter.
“I have to take that huge pill for maths?” inquires the student.
The pharmacist replied “Well, you know maths always was a little hard
to swallow.”

Three standard Peter Lax jokes (heard in his lectures) :
- What’s the contour integral around Western Europe?
Answer: Zero, because all the Poles are in Eastern Europe!
Addendum: Actually, there ARE some Poles in Western Europe, but
they are removable!
- An English mathematician (I forgot who) was asked by his very religious
colleague:
Do you believe in one God?
Answer: Yes, up to isomorphism!
- What is a compact city?
It’s a city that can be guarded by finitely many near-sighted
policemen!
“Algebraic symbols are used when you do not know what you are talking about.”
Heisenberg might have slept here.
Moebius always does it on the same side.
Statisticians probably do it
Algebraists do it in groups.

This poem was written by Jon Saxton (an author of maths textbooks).

A Dozen, a Gross and a Score,
plus three times the square root of four,
divided by seven,
plus five times eleven,
equals nine squared and not a bit more.

Three men are in a hot-air balloon. Soon, they find themselves lost
in a canyon somewhere. One of the three men says, “I’ve got an idea.
We can call for help in this canyon and the echo will carry our voices
far.”
So he leans over the basket and yells out, “Helllloooooo! Where are
we?” (They hear the echo several times.)
15 minutes later, they hear this echoing voice: “Helllloooooo! You’re
lost!!”
One of the men says, “That must have been a mathematician.”
Puzzled, one of the other men asks, “Why do you say that?”
The reply: “For three reasons. (1) he took a long time to answer, (2)
he was absolutely correct, and (3) his answer was absolutely useless.”
(I’m not sure if the following one is a true story or not)
The great logician Bertrand Russell (or was it A.N. Whitehead?)
once claimed that he could prove anything if given that 1+1=1.
So one day, some smarty-pants asked him, “Ok. Prove that
you’re the Pope.”
He thought for a while and proclaimed, “I am one. The Pope
is one. Therefore, the Pope and I are one.”
Lemma: All horses are the same color.
Proof (by induction):
Case n=1: In a set with only one horse, it is obvious that all horses
in that set are the same color.
Case n=k: Suppose you have a set of k+1 horses. Pull one of these
horses out of the set, so that you have k horses. Suppose that all of
these horses are the same color. Now put back the horse that you took
out, and pull out a different one. Suppose that all of the k horses
now in the set are the same color. Then the set of k+1 horses are all
the same color. We have k true => k+1 true; therefore all horses are
the same color.
Theorem: All horses have an infinite number of legs.
Proof (by intimidation):
Everyone would agree that all horses have an even number of legs. It
is also well-known that horses have forelegs in front and two legs in
back. 4 + 2 = 6 legs, which is certainly an odd number of legs for a
horse to have! Now the only number that is both even and odd is
infinity; therefore all horses have an infinite number of legs.
However, suppose that there is a horse somewhere that does not have an
infinite number of legs. Well, that would be a horse of a different
color; and by the Lemma, it doesn’t exist.
Theorem: a cat has nine tails.
Proof:
No cat has eight tails. A cat has one tail more than no cat.
Therefore, a cat has nine tails.
My geometry teacher was sometimes acute, and sometimes
obtuse, but always, he was right.

A doctor, a lawyer and a mathematician were discussing the relative
merits of having a wife or a mistress.
The lawyer says: “For sure a mistress is better. If you have a wife
and want a divorce, it causes all sorts of legal problems.
The doctor says: “It’s better to have a wife because the sense of
security lowers your stress and is good for your health.
The mathematician says: ” You’re both wrong. It’s best to have both so
that when the wife thinks you’re with the mistress and the mistress
thinks you’re with your wife - you can do some mathematics.
Von Neumann and Norbert Wiener were both the subject of many dotty
professor stories. Von Neumann supposedly had the habit of simply
writing answers to homework assignments on the board (the method of
solution being, of course, obvious) when he was asked how to solve
problems. One time one of his students tried to get more helpful
information by asking if there was another way to solve the problem.
Von Neumann looked blank for a moment, thought, and then answered,
“Yes”.
Wiener was in fact very absent minded. The following story is told
about him: When they moved from Cambridge to Newton his wife, knowing
that he would be absolutely useless on the move, packed him off to MIT
while she directed the move. Since she was certain that he would
forget that they had moved and where they had moved to, she wrote down
the new address on a piece of paper, and gave it to him. Naturally,
in the course of the day, an insight occurred to him. He reached in
his pocket, found a piece of paper on which he furiously scribbled
some notes, thought it over, decided there was a fallacy in his idea,
and threw the piece of paper away. At the end of the day he went home
(to the old address in Cambridge, of course). When he got there he
realized that they had moved, that he had no idea where they had moved
to, and that the piece of paper with the address was long gone.
Fortunately inspiration struck. There was a young girl on the street
and he conceived the idea of asking her where he had moved to, saying,
“Excuse me, perhaps you know me. I’m Norbert Wiener and we’ve just
moved. Would you know where we’ve moved to?” To which the young girl
replied, “Yes daddy, mommy thought you would forget.”
The capper to the story is that I asked his daughter (the girl in the
story) about the truth of the story, many years later. She said that
it wasn’t quite true—that he never forgot who his children were!
The rest of it, however, was pretty close to what actually happened…
Old mathematicians never die; they just lose some of their functions.
During a class of calculus my lecturer suddenly checked himself and
stared intently at the table in front of him for a while. Then he
looked up at us and explained that he thought he had brought six piles
of papers with him, but “no matter how he counted” there was only five
on the table. Then he became silent for a while again and then told
the following story:
“When I was young in Poland I met the great mathematician Waclaw
Sierpinski. He was old already then and rather absent-minded. Once he
had to move to a new place for some reason. His wife didn’t trust
him very much, so when they stood down on the street with all their
things, she said:
“Now, you stand here and watch our ten trunks, while I go and get a
taxi.”
She left and left him there, eyes somewhat glazed and humming
absently. Some minutes later she returned, presumably having called
for a taxi. Says Mr. Sierpinski (possibly with a glint in his eye):
“I thought you said there were ten trunks, but I’ve only counted to nine.”
“No, they’re TEN!”
“No, count them: 0, 1, 2, ...”
Two male mathematicians are in a bar.
The first one says to the second that the average person knows very
little about basic mathematics.
The second one disagrees, and claims that most people can cope with a
reasonable amount of math.
The first mathematician goes off to the washroom, and in his absence
the second calls over the waitress.
He tells her that in a few minutes, after his friend has returned, he
will call her over and ask her a question. All she has to do is
answer one third x cubed.
She repeats `one thir—dex cue’? He repeats `one third x cubed’.
Her: `one thir dex cuebd’? Yes, that’s right, he says. So she
agrees, and goes off mumbling to herself, `one thir dex cuebd…’.
The first guy returns and the second proposes a bet to prove his
point, that most people do know something about basic math.
He says he will ask the blonde waitress an integral, and the first
laughingly agrees.
The second man calls over the waitress and asks `what is the integral
of x squared?’.
The waitress says `one third x cubed’ and while walking away, turns
back and says over her shoulder `plus a constant’!
A tribe of Native Americans generally referred to their woman by the
animal hide with which they made their blanket. Thus, one woman might
be known as Squaw of Buffalo Hide, while another might be known as
Squaw of Deer Hide. This tribe had a particularly large and strong
woman, with a very unique (for North America anyway) animal hide for
her blanket. This woman was known as Squaw of Hippopotamus hide, and
she was as large and powerful as the animal from which her blanket was
made.
Year after year, this woman entered the tribal wrestling tournament,
and easily defeated all challengers; male or female. As the men of
the tribe admired her strength and power, this made many of the other
woman of the tribe extremely jealous. One year, two of the squaws
petitioned the Chief to allow them to enter their sons together as a
wrestling tandem in order to wrestle Squaw of the Hippopotamus hide as
a team. In this way, they hoped to see that she would no longer be
champion wrestler of the tribe.
As the luck of the draw would have it, the two sons who were wrestling
as a tandem met the squaw in the final and championship round of the
wrestling contest. As the match began, it became clear that the squaw
had finally met an opponent that was her equal. The two sons wrestled
and struggled vigorously and were clearly on an equal footing with the
powerful squaw. Their match lasted for hours without a clear victor.
Finally the chief intervened and declared that, in the interests of
the health and safety of the wrestlers, the match was to be terminated
and that he would declare a winner.
The chief retired to his teepee and contemplated the great struggle he
had witnessed, and found it extremely difficult to decide a winner.
While the two young men had clearly outmatched the squaw, he found it
difficult to force the squaw to relinquish her tribal championship.
After all, it had taken two young men to finally provide her with a
decent match. Finally, after much deliberation, the chief came out
from his teepee, and announced his decision. He said…
“The Squaw of the Hippopotamus hide is equal to the sons of the squaws
of the other two hides”
A topologist is a man who doesn’t know the difference between a coffee
cup and a doughnut.
A statistician can have his head in an oven and his feet in ice, and
he will say that on the average he feels fine.
A guy decided to go to the brain transplant clinic to refreshen his
supply of brains. The secretary informed him that they had three
kinds of brains available at that time. Doctors’ brains were going
for $20 per ounce and lawyers’ brains were getting $30 per ounce. And
then there were mathematicians’ brains which were currently fetching
$1000 per ounce.
“A 1000 dollars an ounce!” he cried. “Why are they so expensive?”
“It takes more mathematicians to get an ounce of brains,” she explained.
A topologist walks into a bar and orders a drink. The bartender,
being a number theorist, says, “I’m sorry, but we don’t serve
topologists here.”
The disgruntled topologist walks outside, but then gets an idea and
performs Dahn surgery upon herself. She walks into the bar, and the
bartender, who does not recognize her since she is now a different
manifold, serves her a drink. However, the bartender thinks she looks
familiar, or at least locally similar, and asks, “Aren’t you that
topologist that just came in here?”
To which she responds, “No, I’m a frayed knot.”

- Isaac Newton’s birthday.
- I could only get arbitrarily close to my textbook. I couldn’t
actually reach it.
- I have the proof, but there isn’t room to write it in this margin.
- I was watching the World Series and got tied up trying to prove
that it converged.
- I have a solar powered calculator and it was cloudy.
- I locked the paper in my trunk but a four-dimensional dog got in
and ate it.
- I couldn’t figure out whether i am the square of negative one or
i is the square root of negative one.
- I took time out to snack on a doughnut and a cup of coffee.
- I spent the rest of the night trying to figure which one to dunk.
- I could have sworn I put the homework inside a Klein bottle, but
this morning I couldn’t find it.

Mrs. Johnson the elementary school math teacher was having children do
problems on the blackboard that day.
``Who would like to do the first problem, addition?’‘
No one raised their hand. She called on Tommy, and with some help he
finally got it right.
``Who would like to do the second problem, subtraction?’‘
Students hid their faces. She called on Mark, who got the problem but
there was some suspicion his girlfriend Lisa whispered it to him.
``Who would like to do the third problem, division?’‘
Now a low collective groan could be heard as everyone looked at
nothing in particular. The teacher called on Suzy, who got it right
(she has been known to hold back sometimes in front of her friends).
``Who would like to do the last problem, multiplication?’‘
Tim’s hand shot up, surprising everyone in the room. Mrs. Johnson
finally gained her composure in the stunned silence. ``Why the
enthusiasm, Tim?’‘
``God said to go fourth and multiply!’‘
Definitions of Terms Commonly Used in Higher Maths
The following is a guide to the weary student of mathematics who
is often confronted with terms which are commonly used but rarely
defined. In the search for proper definitions for these terms we
found no authoritative, nor even recognized, source. Thus, we
followed the advice of mathematicians handed down from time
immortal: “Wing It.”
- CLEARLY:
- I don’t want to write down all the “in-between” steps.
- TRIVIAL:
- If I have to show you how to do this, you’re
in the wrong class.
- OBVIOUSLY:
- I hope you weren’t sleeping when we discussed
this earlier, because I refuse to repeat it.
- RECALL:
- I shouldn’t have to tell you this, but for
those of you who erase your memory tapes
after every test…
- WLOG (Without Loss Of Generality):
-
I’m not about to do all the
possible cases, so I’ll do one and let you
figure out the rest.
- IT CAN EASILY BE SHOWN:
- Even you, in your finite wisdom, should
be able to prove this without me holding your
hand.
- CHECK or CHECK FOR YOURSELF:
- This is the boring part of the
proof, so you can do it on your own time.
- SKETCH OF A PROOF:
- I couldn’t verify all the details, so I’ll
break it down into the parts I couldn’t
prove.
- HINT:
- The hardest of several possible ways to do a
proof.
- BRUTE FORCE (AND IGNORANCE):
- Four special cases, three counting
arguments, two long inductions, “and a
partridge in a pair tree.”
- SOFT PROOF:
- One third less filling (of the page) than
your regular proof, but it requires two extra
years of course work just to understand the
terms.
- ELEGANT PROOF:
- Requires no previous knowledge of the subject
matter and is less than ten lines long.
- SIMILARLY:
- At least one line of the proof of this case is
the same as before.
- CANONICAL FORM:
- 4 out of 5 mathematicians surveyed
recommended this as the final form for their
students who choose to finish.
- TFAE (The Following Are Equivalent):
- If I say this it means that,
and if I say that it means the other thing,
and if I say the other thing…
- BY A PREVIOUS THEOREM:
- I don’t remember how it goes (come to
think of it I’m not really sure we did this
at all), but if I stated it right (or at
all), then the rest of this follows.
- TWO LINE PROOF:
- I’ll leave out everything but the conclusion,
you can’t question ‘em if you can’t see ‘em.
- BRIEFLY:
- I’m running out of time, so I’ll just write
and talk faster.
- LET’S TALK THROUGH IT:
- I don’t want to write it on the board lest
I make a mistake.
- PROCEED FORMALLY:
- Manipulate symbols by the rules without any
hint of their true meaning (popular in pure
math courses).
- QUANTIFY:
- I can’t find anything wrong with your proof
except that it won’t work if x is a moon of
Jupiter (Popular in applied math courses).
- PROOF OMITTED:
- Trust me, It’s true.
Some famous mathematician was to give a keynote speech at a
conference. Asked for an advance summary, he said he would present a
proof of Fermat’s Last Theorem—but they should keep it under their
hats. When he arrived, though, he spoke on a much more prosaic
topic. Afterwards the conference organizers asked why he said he’d
talk about the theorem and then didn’t. He replied this was his
standard practice, just in case he was killed on the way to the
conference.
When I was a Math/Chem grad student at Princeton in 1973-74, there was
a story going around about a grad student. This guy was always late.
One day he stumbled into class late, saw seven problems written on the
board, and wrote them down. As the week went on he began to panic:
the math department at Princeton is fiercely competitive, and here he
was unable to do most of a simple homework assignment! When the next
class rolled around he only had solved two of the problems, although
he had a pretty good idea of how to solve a third but not enough time
to complete it.
When he dejectedly flung his partial assignment on the prof’s desk,
the prof asked him “What’s that?” “The homework.” “What homework?”
Eventually it came out that what the prof had written on the board
were the seven most important unsolved problems in the field.
This is largely an academic legend, at least according to Jan Harold
Brunvand, the author of a series of books on so-called Urban Legends.
He talks about it in his latest book Curses! Broiled Again! in the
chapter entitled “The Unsolvable Math Problem.” It is, however, based
in some fact. The Stanford mathematician, George B. Danzig,
apparently managed to solve two statistics problems previously
unsolved under similar circumstances.
The following problem can be solved either the easy way or the hard way.
Two trains 200 miles apart are moving toward each other; each one is
going at a speed of 50 miles per hour. A fly starting on the front of
one of them flies back and forth between them at a rate of 75 miles
per hour. It does this until the trains collide and crush the fly to
death. What is the total distance the fly has flown?
The fly actually hits each train an infinite number of times before it
gets crushed, and one could solve the problem the hard way with pencil
and paper by summing an infinite series of distances. The easy way
is as follows: Since the trains are 200 miles apart and each train is
going 50 miles an hour, it takes 2 hours for the trains to collide.
Therefore the fly was flying for two hours. Since the fly was flying
at a rate of 75 miles per hour, the fly must have flown 150 miles.
That’s all there is to it.
When this problem was posed to John von Neumann, he immediately
replied, “150 miles.”
“It is very strange,” said the poser, “but nearly everyone tries to
sum the infinite series.”
“What do you mean, strange?” asked Von Neumann. “That’s how I did it!”
Mathematicians are like Frenchmen: whatever you say to them, they
translate it into their own language, and forthwith it means something
entirely different.

A math/computer science convention was being held. On the train to
the convention, a bunch of math majors and a bunch of computer science
majors were on the train. Each of the math majors had his/her train
ticket. The group of computer science majors had only
ONE ticket for
all of them. The math majors started laughing and snickering.
Then, one of the CS majors said “here comes the conductor” and then
all of the CS majors went into the bathroom. The math majors were
puzzled. The conductor came aboard and said “tickets please” and got
tickets from all the math majors. He then went to the bathroom and
knocked on the door and said “ticket please” and the CS majors stuck
the ticket under the door. The conductor took it and then the CS
majors came out of the bathroom a few minutes later. The math majors
felt really stupid.
So, on the way back from the convention, the group of math majors had
one ticket for the group. They started snickering at the CS majors,
for the whole group had no tickets amongst them. Then, the CS major
lookout said “Conductor coming!”. All the CS majors went to the
bathroom. All the math majors went to another bathroom. Then, before
the conductor came on board, one of the CS majors left the bathroom,
knocked on the other bathroom, and said “ticket please.”
The following is supposedly a true story about Russell. It isn’t
really a math joke since it makes fun of the British hierarchy, but
it’s funny anyway….
Around the time when Cold War started, Bertrand Russell was giving a
lecture on politics in England. Being a leftist in a conservative
women’s club, he was not received well at all: the ladies came up to
him and started attacking him with whatever they could get their hands
on. The guard, being an English gentleman, did not want to be rough
to the ladies and yet needed to save Russell from them. He said, “But
he is a great mathematician!” The ladies ignored him. The guard said
again, “But he is a great philosopher!” The ladies ignore him again.
In desperation, finally, he said, “But his brother is an earl!” Bert
was saved.
Another “true” story, kinda like the aforementioned urban legend:
Enrico Fermi, while studying in college, was bored by his math
classes. He walked up to the professor and said, “My classes are too
easy!” The professor looked at him, and said, “Well, I’m sure you’ll
find this interesting.” Then the professor copied 9 problems from a
book to a paper and gave the paper to Fermi. A month later, the
professor ran into Fermi, “So how are you doing with the problems I
gave you?” “Oh, they are very hard. I only managed to solve 6 of
them.” The professor was visibly shocked, “What!? But those are
unsolved problems!”
