Alice and Bob go into this bar. It's late at night and they're drunk. They get a drink each and go off into their corner. They start gettinging a bit frisky, and kissing and canoodleing. The barman isn't too happy, but seeing as they're such good customers, he lets it slide. Before too long, though, they're both naked, and getting down to it.
The barman covers his eyes, trying not to look. As he sneaks a glimpse through his fingers, he sees something wierd - he can't make out what they're doing. He looks again, but is still confused. He turns to the drunk propping up the bar next to him, and asks, "What's going on? He seems to be screwing her over the table AND getting a blowjob at the same time. That doesn't make any sense. Looks brilliant though, doesn't it?"
"Yeh," sighs the drunk whistfully, "It's a super position."

Heisenberg is pulled over for speeding:
"Do you know how fast you were going?" the police officer asks, incredulously.
"No," replies Heisenberg, "but I know exactly where I am!"

Q. What did the zero say to the number eight?
A. Nice belt!

At Heathrow Airport today, an individual later discovered to be a public school teacher was arrested trying to board a flight while in possession of a compass, a protractor, and a graphical calculator. Authorities believe he is a member of the notorious al-Gebra movement. He is being charged with carrying weapons of math instruction.

Physics professor is walking across campus, runs into Math Professor. Physics professor has been doing an experiment, and has worked out an empirical equation that seems to explain his data, and asks the Math professor to look at it. A week later, they meet again, and the Math professor says the equation is invalid. By then, the Physics professor has used his equation to predict the results of further experiments, and he is getting excellent results, so he askes the Math professor to look again. Another week goes by, and they meet once more. The Math professor tells the Physics professor the equation does work, "But only in the trivial case where the numbers are real and positive."

Question: Why is this a mathematical limerick?
( (12 + 144 + 20 + 3 Sqrt[4]) / 7 ) + 5*11 = 81 + 0 .

A dozen, a gross, and a score,
plus three times the square root of four,
divided by seven,
plus five times eleven,
is nine squared and not a bit more.

Here's a calculus limerick:
Integral z-squared dz
from 1 to the cube root of 3

When the math professor's wife returns home from work, she finds an envelope on the living room table. She opens it and finds a letter from her husband:
My dearest wife,

We have been married for nearly thirty years, and I still love you as much as on the day I proposed. You must realize, however, that you are now 54 years old and no longer able to satisfy certain needs I still have. I very much hope that you are not hurt to learn that, while you're reading this, I'm in a hotel room with an 18-year-old freshman girl from my calculus class. I'll be home before midnight.

Your husband, who will never stop loving you.
When the professor returns from the hotel shortly before midnight, he also finds an envelope in the living room. He opens it and reads:
My beloved husband,

You may recall that you, too, are 54 years old and no longer able to satisfy certain needs I still have. I thus hope that you are not hurt to learn that, while your're reading this, I am in a hotel room with the 18-year-old pool boy.

Your loving wife.

P.S. As a mathematician, you are certainly aware of the fact that 18 goes into 54 many more times than 54 goes into 18. Therefore, don't stay up and wait for me.

"Divide fourteen sugar cubes into three cups of coffee so that each cup has an odd number of sugar cubes in it." "That's easy: one, one, and twelve." "But twelve isn't odd!" "It's an odd number of cubes to put in a cup of coffee..."

Every new scientist must learn early that it is never good taste to
designate the sum of two quantities in the form:

                1 + 1 = 2                                               (1)

Anyone who has made a study of advanced mathematics is aware that:
        1 = ln e
        1 = sin^2 x + cos^2 x

        2 = sum     1/2^n

Therefore eq. (1) can be expressed more scientifically as:

ln e + sin^2 x + cos^2 x =   sum     1/2^n                              (2)

This may be further simplified by use of the relations:

        1 = cosh y sqrt(1 - tanh^2 y)
        e = lim     (1+1/z)^z
            z-> inf

Equation (2) may therefore be rewritten as:

                                           inf  cosh y sqrt(1 - tanh^2 y)
ln[ lim (1+1/z)^z ] + sin^2 x + cos^2 x =  SUM  ____________________________
    z-> inf                                n=0             2^n


At this point it should be obvious that eq. (3) is much clearer and more
easily understood than eq. (1). Other methods of a similar nature could be
used to clarify eq. (1), but these are easily divined once the reader
grasps the underlying principles.

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."

In some foreign country, a physicist, a mathematician, and an engineer are about to be guillotined. The physicist puts his head on the block, they pull the rope and nothing happens. "Aha," the physicist says, "KE = 1/2 mv**2 ; v=0 so all is well." He declares that he can't be executed twice for the same crime so he is set free. The mathematician is put on the block, and again the rope doesn't release the blade. He exclaims "the events are equally likely, so P(E)=1/2 and all is well." Likewise he cannot be executed twice for the same crime and is set free. They grab the engineer and shove his head into the guillotine, he looks up at the release mechanism and says, "Wait a minute, I see your problem....."

This story should have a happy ending. Here it is...
The executioner turns out to be a Biometrician doing a field experiment using the guillotine. He declares, "Sorry, I can't change the plot settings right now or the experiment will be invalid." He then pulls the rope with the same result and the engineer is also set free.

Q: Did you hear the one about the statistician?

Q. "What do you get when you cross an elephant with a banana?
A. Elephant banana sine theta in a direction mutually perpendicular to the two as determined by the right hand rule."

Q. What do you get if you cross an elephant with a mountain climber?
A. You can't do that. A mountain climber is a scalar.

Three statisticians go out hunting together. After a while they spot a solitary rabbit. The first statistician takes aim and overshoots. The second aims and undershoots. The third shouts out "We got him!"

The Evolution Of The Maths Problem
  • Problem from a 1950s textbook: A logger sells a truckload of lumber for $100.00. His cost of production is 4/5 of the price. What is his profit?
  • From a 1960s textbook: a logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price, or $80. What is his profit?
  • From a 1970s textbook: logger exchanges a set of L of lumber for a set M of money. The cardinality of set M is 100. Each element is worth one dollar. Make 100 dots representing the elements of set M. Represent the set C as a subset of M and P, the profits, as a union of M and not C. What is the cardinality of P? From a 1980s textbook: a logger sells a truckload of lumber for $100. Her cost of production is $80 and her profit is $20. Your assignment: Underline the number 20.
  • From a 1990 textbook: By cutting down a beautiful forest, the logger makes $20. What do you thinks about this way of making a living? Topic for class participation after answering the question: How did the forest birds and animal feel as the logger cuts down the trees? (There are no wrong answers)
  • From a 1996 textbook: By laying off 40% of its loggers, a company improves its stock price from $80 to $100. How much capital gain per share does the CEO make by exercising his stock options at $80? Assume capital gains are no longer taxed, because this encourages investment.
  • From a 1997 textbook: a company outsources all its loggers. The firm saves on benefits, and when the demand for its product is down, the logging workforce can be easily cut back. The average logger employed by the company earned $50,000, had three weeks paid holiday, a nice retirement plan and medical insurance. The contracted logger charges $50 an hour. Was the outsourcing a good move?
  • From a 1998 textbook: a laid off logger with four kids at home and a ridiculous alimony from his first failed marriage comes into the logging company corporate offices and goes berserk, mowing down 16 executives and a couple of secretaries, and gets lucky when he nails a politician collecting his kickback. Was the outsourcing of loggers a good move for the company?
  • From a 1999 textbook: A laid off logger serving time in a high security jail for blowing away several people is being trained as a COBOL programmer in order to work on Y2K projects. What is the probability that the cell doors will open on their own at 00:00:01 01/01/2000?

  • Topologists do it openly.
  • Topologists do it on rubber sheets.
  • Dynamicists do it chaotically.
  • Mathematicians do it forever if they can do one and can do one more.
  • Cantor did it diagonally.
  • Fermat tried to do it in the margin, but couldn't fit it in.

How to catch a lion:
- THE HILBERT METHOD. Place a locked cage in the desert.
Set up the following axiomatic system.
(i) The set of lions is non-empty
(ii) If there is a lion in the desert, then there is a lion in the cage.
Theorem. There is a lion in the cage
- THE PEANO METHOD. There is a space-filling curve passing through every point of the desert. Such a curve may be traversed in as short a time as we please. Armed with a spear, traverse the curve faster than the lion can move his own length.
- THE TOPOLOGICAL METHOD. The lion has a least the connectivity of a torus. Transport the desert into 4-space. It can now be deformed in such a way as to knot the lion. He is now helpless.
- THE SURGERGY METHOD. The lion is an orientable 3-manifold with boundary and so may be rendered contractible by surgery.
- THE UNIVERSAL COVERING METHOD. Cover the lion by his simply-connected covering space. Since this has no holes, he is trapped.
- THE GAME THEORY METHOD. The lion is a big game, hence certainly a game. There exists an optimal strategy. Follow it.
- THE SCHROEDINGER METHOD. At any instant there is a non-zero probability that the lion is in the cage. Wait.
- THE ERASTOSHENIAN METHOD. Enumerate all objects in the desert: examine them one by one; discard all those that are not lions. A refinement will capture only prime lions.
- THE PROJECTIVE GEOMETRY METHOD. The desert is a plane. Project this to a line, then project the line to a point inside the cage. The lion goes to the same point.
- THE INVERSION METHOD. Take a cylindrical cage. First case: the lion is in the cage: Trivial. Second case: the lion is outside the cage. Go inside the cage. Invert at the boundary of the cage. The lion is caught. Caution: Don't stand in the middle of the cage during the inversion!

So there's a bunch of functions hanging out in function bar. They're all talking when in walks e^x. He orders a beer, sits down and starts drinking. Shortly thereafter in rushes a little x^2 function and exclaims "The Derivative Operators are coming! The Derivative Operators are coming!". All the functions in the bar start looking around nervously and some start to leave. All except for e^x who just sits there an continues drinking his beer. The x^2 function goes up to him and says "Didn't you hear me? The Derivative Operators are coming!". e^x says "Yeah, but I'm e^x". Two minutes later the Derivative Operators enter the bar and the head Derivative Operator says "I'm d/dy", e^x says "Ahh $hit.."

Two male mathematiciens 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 mathematicien 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'!

Old mathematicians never die; they just lose some of their functions.

So this girl in high school is not doing very well in math class. Her mother hears that this Catholic school has an excellent math program so switches her daughter to the Catholic school. It has an amazing effect! Every day after school her daughter studies math and does her homework. After recieving her finaly grade of an A+ her mother is really impressed! So one day she asks her daughter "What made such a difference at the new school?" and the daughter replies "Well, when I saw that man nailed to the plus sign the first day I knew they meant business!"

Once a programmer drowned in the sea. Many Marines where at that time on the beach, but the programmer was shouting "F1 F1" and nobody understood it.

Jack was a COBOL programmer in the mid to late 1990s. After years of being taken for granted and treated as a technological dinosaur by all the Client/Server programmers and website developers, he was finally getting some respect. He'd become a private consultant specializing in Year 2000 conversions.
Several years of this relentless, mind-numbing work had taken its toll on Jack. He began having anxiety dreams about the Year 2000. All he could think about was how he could avoid the year 2000 and all that came with it.
Jack decided to contact a company that specialized in cryogenics. He made a deal to have himself frozen until March 15th, 2000. The next thing he would know is he'd wake up in the year 2000; after the New Year celebrations and computer debacles; after the leap day. Nothing else to worry about except getting on with his life.
He was put into his cryogenic receptacle, the technicians set the revive date, he was given injections to slow his heartbeat to a bare minimum, and that was that.
The next thing that Jack saw was an enormous and very modern room filled with excited people. They were all shouting "I can't believe it!" and "It's a miracle" and "He's alive!". There were cameras (unlike any he'd ever seen) and equipment that looked like it came out of a science fiction movie.
Someone who was obviously a spokesperson for the group stepped forward. Jack couldn't contain his enthusiasm. "Is it over?" he asked. "Is the year 2000 already here? Are all the millennial parties and promotions and crises all over and done with?"
The spokesman explained that there had been a problem with the programming of the timer on Jack's cryogenic receptacle, it hadn't been year 2000 compliant. It was actually eight thousand years later, not the year 2000. Technology had advanced to such a degree that everyone had virtual reality interfaces which allowed them to contact anyone else on the planet.
"That sounds terrific," said Jack. "But I'm curious. Why is everybody so interested in me?"
"Well," said the spokesman. "The year 10000 is just around the corner, and it says in your files that you know COBOL".

In C we had to code our own bugs. In C++ we can inherit them.

C gives you enough rope to hang yourself. C++ also gives you the tree object to tie it to.

Q. Why are all Pascal programmers ask to live in Atlantis?

Top ln(e^10) reasons why e is better than pi

10) e is easier to spell than pi.
9) pi ~= 3.14 while e ~=2.718281828459045.
8) The character for e can be found on a keyboard, but pi sure can't.
7) Everybody fights for their piece of the pie.
6) ln(pi^1) is a really nasty number, but ln(e^1) = 1.
5) e is used in calculus while pi is used in baby geometry.
4) 'e' is the most commonly picked vowel in Wheel of Fortune.
3) e stands for Euler's Number, pi doesn't stand for squat.
2) You don't need to know Greek to be able to use e.
1) You can't confuse e with a food product.

Top ten reasons why e is inferior to pi

10) e is less challenging to spell than pi.
9) e ~=2.718281828459045, which can be easily memorized to its billionth place, whereas pi needs "skills" to be memorized.
8) The character for e is so cheap that it can be found on a keyboard. But is special (it's under "special symbols" in word processor programs.)
7) Pi is the bigger piece of pie.
6) e has an easy limit definition and infinite series. The limit definition of pi and the infinite series are much harder.
5) e you understand what it is even though you start learning it late when you're in pre-calculus. But pi, even after five or six years it's still hard to know what it really is.
4) People mistakenly confuse Euler's Number (e) with Euler's Constant (gamma). There is no confusion with the one and only .
3) e is named after a person, but pi stands for itself.
2) Pi is much shorter and easier to say than "Euler's Number".
1) To read pi, you don't have to know that Euler's name is really pronounced Oiler.

One day a mathematician decides that he is sick of math. So, he walks down to the fire department and announces that he wants to become a fireman. The fire chief says, "Well, you look like a good guy. I'd be glad to hire you, but first I have to give you a little test."
The firechief takes the mathematcian to the alley behind the fire department which contains a dumpster, a spicket, and a hose. The chief then says, "OK, you're walking in the alley and you see the dumpster here is on fire. What do you do?" The mathematician replies, "Well, I hook up the hose to the spicket, turn the water on, and put out the fire."
The chief says, "That's great... perfect. Now I have to ask you just one more question. What do you do if you're walking down the alley and you see the dumpster is not on fire?" The mathematician puzzles over the question for awhile and he finally says, "I light the dumpster on fire." The chief yells, "What? That's horrible! Why would you light the dumpster on fire?" The mathematician replies, "Well, that way I reduce the problem to one I've already solved."

The Dictionary: what mathematics professors say and what they mean by 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.
  • It can easily be shown: No more than four hours are needed to prove it.
  • Check for yourself: This is the boring part of the proof, so you can do it on your own time.
  • Hint: The hardest of several possible ways to do a proof.
  • Brute force: Four special cases, three counting arguments and two long inductions.
  • 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.
  • 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.
  • Proceed formally: Manipulate symbols by the rules without any hint of their true meaning.
  • Proof omitted: Trust me, It's true.

There was once a very smart horse. Anything that was shown it, it mastered easily, until one day, its teachers tried to teach it about rectangular coordinates and it couldn't understand them. All the horse's acquaintances and friends tried to figure out what was the matter and couldn't. Then a new guy looked at the problem and said,
"Of course he can't do it. Why, you're putting Descartes before the horse!"

An astronomer, a physicist and a mathematician (it is said) were holidaying in Scotland. Glancing from a train window, they observed a black sheep in the middle of a field.
"How interesting," observed the astronomer, "all scottish sheep are black!"
To which the physicist responded, "No, no! Some Scottish sheep are black!"
The mathematician gazed heavenward in supplication, and then intoned, "In Scotland there exists at least one field, containing at least one sheep, at least one side of which is black."

A biologist, a statistician, a mathematician and a computer scientist are on a photo-safari in africa. They drive out on the savannah in their jeep, stop and scout the horizon with their binoculars.
The biologist: "Look! There's a herd of zebras! And there, in the middle : A white zebra! It's fantastic! There are white zebra's! We'll be famous!"
The statistician: "It's not significant. We only know there's one white zebra."
The mathematician: "Actually, we only know there exists a zebra, which is white on one side."
The computer scientist: "Oh, no! A special case!"

A mathematician, a biologist and a physicist are sitting in a street cafe watching people going in and coming out of the house on the other side of the street.
First they see two people going into the house. Time passes. After a while they notice three persons coming out of the house.
The physicist: "The measurement wasn't accurate." The biologists: "They have reproduced". The mathematician: "If now exactly one person enters the house then it will be empty again."

So after the floods start to receed, Noah drops all the animals off onto the emerging land. Then he decides to take a nice vacation all by himself. When he comes back a few months later all the animals have multiplied and are living happily. All the animals except the snakes that is.
When Noah asks the snakes why they haven't flourished they tell him to cut down some trees for them. Not understanding why, he does so and then takes another vacation.
After Noah's second vacation he comes back and finds the snakes have reproduced too. He asks them what was different and they reply, "We're adders, we need logs to multiply!"

Interesting Theorem:
All positive integers are interesting.
Assume the contrary. Then there is a lowest non-interesting positive integer. But, hey, that's pretty interesting! A contradiction.

Cat Theorem:
A cat has nine tails.
No cat has eight tails. A cat has one tail more than no cat. Therefore, a cat has nine tails.

Salary Theorem
The less you know, the more you make.
Postulate 1: Knowledge is Power.
Postulate 2: Time is Money.
As every engineer knows: Power = Work / Time
And since Knowledge = Power and Time = Money
It is therefore true that Knowledge = Work / Money .
Solving for Money, we get:
Money = Work / Knowledge
Thus, as Knowledge approaches zero, Money approaches infinity, regardless of the amount of Work done.

A physicist and an engineer are in a hot-air balloon. They've been drifting for hours, and have no idea where they are. They see another person in a balloon, and call out to her: "Hey, where are we?" She replies, "You're in a balloon," and drifts off again. The engineer says to the physicist, "That person was obviously a mathematician." They physicist replies, "How do you know that?" "Because what she said was completely true, but utterly useless."

Theorem: 1=2
1.let A=1
2.let B=A
3.multiply both sides of (2.) by A, you get AB=A2
4.subtract B2 from both sides, you get AB-B2=A2-B2
5.factor left and right hand sides, you get B(A-B)=(A-B)(A+B)
6.divide both sides by (A-B), you get B=A+B
7.plug A=1 and B=A into (6.), you get 1=2

Q: What does a mathematician do when he's constipated?
A: He works it out with a pencil.

One day a farmer called up an engineer, a physicist, and a mathematician and asked them to fence of the largest possible area with the least amount of fence. The engineer made the fence in a circle and proclaimed that he had the most efficient design. The physicist made a long, straight line and proclaimed 'We can assume the length is infinite...' and pointed out that fencing off half of the Earth was certainly a more efficient way to do it. The Mathematician just laughed at them. He built a tiny fence around himself and said 'I declare myself to be on the outside.'
