# Open thread for science and math jokes!

It's Thursday afternoon and I'm feeling a bit silly, so I'm putting out a call for everyone to share their favorite groan-inducing, head-slapping, pun-laden science and math jokes. Here's a couple to start us out:

From The Republic of Math on Twitter

Q: Why couldn't Pythagoras get a car loan?

A: He couldn't find anyone to cosine!

I can't remember where I heard this joke, but as the wife of an engineer, it amuses me.

Three men—a mathematician, a biologist, and an engineer—are discussing their love lives. The mathematician starts off talking about how much he loves having a wife. She takes care of him. She always there for him. She's so constant, just everything he could want.

But the biologist disagrees. "What you really need is a mistress," he says. "My wife is boring, but my mistress always makes sure there's something new and exciting going on."

Those two argue back and forth for a little while until, finally, they ask the engineer to break the tie. Which is better, a wife, or a mistress?

"I like having both," says the engineer. "That way, one of them always assumes I'm off spending time with the other one, and I can go into the office and get some work done."

Q: what’s a polar bear?
A: a rectangular bear with another set of coordinates.

1. penguinchris says:

I think the repeats in here certainly illustrate how important delivery of a joke is, even just in written form!

The “correct” version of the polar bear joke is something like “a polar bear is a cartesian bear after a coordinate transform.”

I think the joke got changed by some people to “rectangular” (which doesn’t make sense) because people don’t know what cartesian and polar coordinates are?

Anyway to make up for this comment, here’s a joke:

Q: How many petroleum geologists does it take to screw in a lightbulb?

Sorry, all I’ve got is a philosophy joke.

Rene Descartes goes into a bar and asks for their cheapest domestic beer. The bartender recognizes him as the famous French philosopher and asks if he wouldn’t prefer a nice snifter of brandy. Descartes says “No, I think not” and *poof*, he disappears.

1. Jonathan Badger says:

Speaking of Descartes (who actually counts as a mathematician besides a philosopher), his last job was as a mathematics tutor to the Queen of Sweden (this is true, btw)

Anyway, the story goes that the Queen’s schedule was so packed that the only time they had was before her morning riding lesson. Descartes, being elderly and Sweden being cold, contracted pneumonia from getting up so early on chilly mornings and died. So the moral from this was “Don’t put Descartes before the horse”.

An engineer, physicist and mathematician all stay in a hotel. Carpet fires break out in each of their rooms. The engineer climbs out the window, gets the gardeners hose, fills the room to 2″ and goes back to sleep. The physicist looks at the volume of air, material of the carpet, goes to the bathroom, gets .6 liters of water, dumps it on the carpet and goes back to sleep. The mathematician looks at the fire, the size of the room, concludes the problem is easily solvable and goes back to sleep.

A physicist, a chemist, and a mathematician are given a test to determine which profession is inherently smarter. The chemist is led into a small kitchen and said “The test is to see who perform the following task most efficiently. Boil a gallon of water.”

The chemist reaches into a cabinet, takes out a pot, fills it at the sink, places it on a burner, and waits. After all, what else can he do?

The physicist saw the performance and said “I can improve on this”. So he pulled out four pots, fills each with a quarter gallon, and boils each on a separate burner, chuckling at his own cleverness.

The mathematician can’t wait to show off HIS method, so after the physicist is done, the mathematician shoulders him aside, pours out all the water, turns off the stove, puts away the pots, and says “I have reduced this to a previously solved problem.”

An engineer, physicist, and mathematician are all working in their offices late at night, when fires spontaneously erupt in each of their trash cans.

The engineer rushes to his feet, looks at the trash can, estimates the amount of water needed to extinguish it, fills a bucket, and puts the fire out. Then the engineer packs his briefcase, turns the lights off, and leaves.

The physicist also looks at his trash can, does a brief calculation to determine the amount of water needed, fills a bucket, and puts the fire out. Then he packs his briefcase, turns the lights off, and leaves.

The mathematician turns and looks at his trash can, pulls out his notepad, and writes an elegant proof showing exactly how much water would be needed to put the fire out (for any geometry trash can). Then he packs his briefcase, turns the lights off, and leaves.

A geneticist, a physiologist and a physicist are summoned by a millionaire horse enthusiast. He offers \$1 million to the person who can devise a sure-fire method for choosing a winning horse.

Six months later, the scientists return. The geneticist reports “I tried everything, but there are too many environmental factors. I can’t predict which horse will win.”

The physiologist says “I tried everything, but there are too many genetic factors. I can’t predict which horse will win.”

“Oh dear,” the millionaire says. “And what about you?” he asks the physicist.

Einstein, Newton, and Pascal are in heaven and quite bored, so they decide to play a game of hide-and-seek. Einstein is “it”, so starts counting. Pascal runs off to hide, while Newton just moves a few meters away from Einstein, takes a piece of chalk out of his pocket, and draws a 1m x 1m square on the ground around his feet.

Einstein finishes counting and opens his eyes to see Newton standing right in front of him. Confused, he tells Newton that he’s out and asks Newton if he understands the rules of the game.

Newton calmly replies, “I’m not out. Pascal is out.”

Explanation: the Newton is the SI unit for Force. The Pascal is the SI unit for pressure, defined as force divided by area. 1 Pascal is 1 Newton (of Force) / 1 square meter.

THE SEX LIFE OF THE ELECTRON

by D.C. Current

One night when his charge was high, Micro-Farad decided to find a cute little coil to let him discharge.

He picked up Millie-Amp and took her for a ride on his Megacycle. They rode across the Wheatstone Bridge, around the sine waves and stopped in the magnetic field by a flowing current.

Micro-Farad, attracted by Millie-Amps characteristic curves, soon
had her fully charged and excited her resistance to a minimum. He laid her on the ground potential, raised her frequency and lowered her reluctance.

He pulled out his high voltage probe and inserted it in her socket
connecting them in parallel, and began to short circuit her
shunt. Fully excited, Millie-Amp shouted, “Mho! Mho! Mho!”

With his tube operating at maximum power and her field vibrating with his current flow, caused her shunt to overheat and Micro-Farad was rapidly discharged and drained of every electron.

They fluxed all night, trying various connections and sockets,
until his magnet dipole lost all of it’s field strength.

Afterward, Millie-Amp tried self induction and damaged her
solenoid. With his battery fully discharged, Micro-Farad was unable to excite his field, so they spent the rest of the night reversing polarity and blowing each others fuses.

The moral of the story: When the flux is flowing, don’t forget your webers.

The physicist looks at the fire, calculates the optimal angle and force at which to throw an optimal amount of water and proceeds to do so, putting the fire out. He then goes back to bed. A fire then breaks out outside the engineers room. He gets up, estimates the amount of water needed then adds a safety margin of 50% and throws the water on the fire. Satisfied he goes back to bed. Next a fire breaks out outside the mathematician’s room. He gets up looks at the fire, looks at the water tap in his room,says,”A solution exists,” and goes back to bed.

Integration by Parts

Once upon a time pretty little Polly Nomial was strolling across a field of vectors when she came to the boundary of a singularly large matrix. Now Polly was convergent, and her mother had made it an absolute condition that she must never, ever enter such an array without her brackets on. Polly, however, who had changed her variables that morning and was feeling particularly badly behaved, she ignored this condition on the basis that it was insufficient, and made her way amongst the complex elements.

Rows and columns closed in on her from all sides. Tangents approach her surface, and she became tensor and tensor. Quite suddenly, two branches of a hyperbola touched her at a single point. She oscillated violently, became unstable, lost all sense of directrix, tripped over a square root that was protruding from the erf, and plunged headlong down a steep gradient. She was completely divergent by the time she reached the turning point. When she rounded off once more, she found herself inverted apparently alone in a non-euclidean space. She was being watched, however.

The smooth operator, Curly Pi, was lurking inner product. As his eyes devoured her curvilinear, a singular expression crossed his face. He wondered, was she convergent? He decided to integrate improperly at once. Hearing a common fraction behind her, Polly rotated and saw Curly Pi approaching with his lower series extended. She could see at once his degenerate conic and his dissipative terms, and knew he was irrational. “Arcsinh!” she gasped.

“Hey, what’s your sign?” he asked. “What a symmetric set of asymptotes you have!” “Stay away from me!” she protested. “I haven’t got any brackets on!” “Calm yourself, my dear!” said the smooth operator. “Your fears are purely imaginary.” “i,i,â€¦” she thought, “Perhaps he’s not normal, but homologous.” “What order are you?” the brute suddenly demanded. “Seventeen,” replied Polly. Curly leered, “I suppose you’ve never been operated upon?” “Of course not.”

“I’m absolutely convergent!” Polly replied quite properly. “Come on.” Said curly: “Let’s go to a decimal place I know of and I’ll take you to the limit.” “Never!” gasped Polly. “Abscissa!” he swore a violent oath. Coshing her over the coefficient with a log until she was powerless, Curly removed her discontinuities.

He stared at her significant places, and began smoothing her points of inflection. Poor Polly Nomial. She had no escape algorithm. She felt him approaching her asymptotic limit. Her convergence would soon be gone for ever. There was no mercy; Curly was a heavy side operator.

His radius squared itself and Polly’s loci quiverd. He integrated by parts. He integrated by partial fractions. Ager he cofactored, he performed Runge-Kutta on her. He even went all the way around and did a contour integration. Curly went of operating until he satisfied his hypotheses, then he exponentiated and became completely orthogonal.

When Polly got home that night, her mother noticed that she was no longer piecewise continuous, but had been truncated in several places. But it was too late to differentiate now. As the months went by, Polly’s denominator increased monotonically. Finally they took her to L’Hopital and generated a small but pathological function which left surds all over the place and drive Polly to deviation.

The moral of this tale is: “If you want to keep your expressions convergent, never allow a single degree of freedom.”

Once all the scientists die and go to heaven. They decide to play hide-n-seek.

Unfortunately Einstein starts by counting up to 100 and then starts searching…

Everyone starts hiding except Newton.

Newton just draws a square of 1 meter and stands in it right in front of Einstein.

Einstein’s counting 1,2,3……97, 98,99, 100. He opens his eyes and finds Newton standing in front of him!

Einstein says “newton’s out..newton’s out”

Newton denies and says “I am not out, after-all I am not Newton”

All the scientists come out to see how he proves that he is not Newton.

Newton says “I am standing in a square of area 1m squared that makes me Newton per meter squared”

since one Newton per meter squared is one Pascal, I’m Pascal, Therefore Pascal is OUT!

A mathematical biologist was out walking in the countryside and met a shepherd with a large flock of sheep. He says to the shepherd
“If I can tell you exactly how many sheep you have in this field will you give me one?”
The shepherd looks surprised but agrees. The mathematician looks around and by applying some clever methodology says
“273.”
“That’s exactly right” says the astonished shepherd “choose which ever you like.”
The mathematician chooses his prize and picks it up. The shepherd then says
“If I can say exactly what you do for a living, will you give me the animal back?”
They agree on the bet and the shepherd says “mathematical biologist”
“How ever did you know that?” replies the dumbfounded academic.
“Well, you obviously had some clever method for counting sheep so I thought you were some kind of mathematician. But what really clinched it was when you picked up my sheep dog”.

Next, he removes the frog’s front legs and yells again. The frog is unhappy, but manages to jump. The scientist measures the distance and dutifully records “two legs – two feet”

The dog runs off and comes back 20 minutes later with six ducks that she arranged in a hexagon in front of them. Engineering guy laughs and gives instructions in Fortran to his bitch Iterate, who promptly gathers logs and clay, builds a Dutch oven over the birds, and starts the fire by wagging her tail covered, which she has covered in oak bark over kindling she make by chewing. The engineer is dejected and they all watch the birds cook. The Engineer says “So, you give up, theory boy? The physicist just shakes his head like he’s been talking to a retard, and says in plain English to his popinter: “Tycho, you know what to do- go do it boy!”. So Tycho wolfs down all 6 ducks and screws the other two dogs.

A mathematician, a physist and an engineer are each locked in a room by psychologists with nothing but a tins of baked beans and a couple of pencils.

After a week they open up the doors to find out what has happened.

The Engineer is covered in beans as is his room which also has a large number of dents in the wall but he is well and happy.

They open the physicists door to find some calculations on the walls and a single precise dent and a rather sharp pencil wedge in it. He is also quite happy if a bit bored of beans.

They open the mathematicians door to find a dead mathematician and walls covered in increasingly frantic calculations. They are baffled and examine the frantic scribbling on the walls. After a while they find the place where he had started work. In big clear letters it says;

A feminist behavioral psychologist, who is trying to prove female monkeys are smarter than male ones, turns red with rage when her male subjects jack off at her. She has set up 5 identical rooms, each with a banana hanging from the ceiling and enough tinker-toy-like scaffolding for the critter to reach the fruit once assembled. Sh put the first female in her room-after 6 hours the monkey figures it out and eats. The second monkey never gets the idea, so after 12 hours they abort that part of the trial. The third female monkey solves it in 5 hours, the fourth in 8 hours. Two minutes after they put the guy in the room, he climbs up on the door knob and jacks off onto the glass plate that the psychologist is watching him through. She curses and runs into the room to punish him. He instantly jumps on her head and grabs and eats the banana.

It was autumn, and the Native Americans on the remote reservation asked their new Chief if it was going to be a cold winter. Raised in the ways of the modern world, the Chief had never been taught the old secrets and had no way of knowing whether the winter would be cold or mild. To be on the safe side, he advised the tribe to collect wood and be prepared for a cold winter. A few days later; as a practical afterthought, he called the National Weather Service and asked whether they were forecasting a cold winter. The meteorologist replied that, indeed, he thought the winter would be quite cold. The Chief advise his tribe to collect even more wood.

A couple of weeks later, the Chief called the National Weather Service again.
“Does it still look like a cold winter?”
“It sure does,” replied the meteorologist. “It’s looks like a very cold winter.”
The Chief advised his tribe to collect every scrap of wood they could find.

Again, a couple of weeks later, he called the National Weather Service and asked how the winter was looking at that point.
The meteorologist said, “We’re now forecasting that it will be one of the coldest winters on record!”
“Really?” said the Chief. “How can you be so sure?”

The mathematician takes the barometer to the top of the building and thows it off. He counts how long it takes to hit the ground an uses that to calculate the height of the building.

the engineer goes to the basement of the building and finds the building engineer. He says to him “If you’ll tell me the height of this building I’ll give you this fine barometer…”

PROOF THAT ALL HORSES ARE WHITE:
Assume a single white horse in a room. All horses in the room are white, so the proof holds for n=1. Assume k white horses, and consider the case of k+1 horses. If we remove any one horse, we are left with k horses, which, by hypothesis, are all the same color. Since we removed an arbitrary horse, all k+1 horses are white.

PROOF THAT HORSES HAVE AN INFINITE NUMBER OF LEGS:
Horses have four legs. In the back, they have two legs, and in the front, they have forelegs. That makes six legs total. Six legs is an odd number of legs for a horse to have. But six is an even number! The only number that is odd and even is infinity. Therefore, horses have an infinite number of legs.

PROOF THAT ALEXANDER THE GREAT DID NOT EXIST, AND ALSO THAT HE HAD AN INFINITE NUMBER OF ARMS:
Alexander the Great rode into battle on a large black horse, which cannot exist per proof 1 above. Therefore, Alexander the Great did not exist.
Alexander the Great said that “Forewarned is forearmed”. Four arms is an odd number of arms for a person to have, but four is an even number. The only number that is both odd and even is infinity. Therefore, Alexander the Great had an infinite number of arms.

He positively laughs as he passes |x| for being nondifferentiable at the origin. He smiles, thinking to himself, “Damn, it’s great to be e^x. I’m real analytic everywhere. I’m my own derivative. I blow up faster than anybody and shrink faster too. All the other functions suck.”

Lost in his own egomania, he collides with the constant function 3, who is running in terror in the opposite direction.

“What’s wrong with you? Why don’t you look where you’re going?” demands e^x. He then sees the fear in 3’s eyes and says “You look terrified!”

“I am!” says the panicky 3. “There’s a differential operator just around the corner. If he differentiates me, I’ll be reduced to nothing! I’ve got to get away!” With that, 3 continues to dash off.

“Stupid constant,” thinks e^x. “I’ve got nothing to fear from a differential operator. He can keep differentiating me as long as he wants, and I’ll still be there.”

There are approximately two billion children (persons under 18) in the world. However, since Santa does not visit children of Muslim, Hindu, Jewish or Buddhist (except maybe in Japan) religions, this reduces the workload for Christmas night to 15% of the total, or 378 million (according to the population reference bureau). At an average (census) rate of 3.5 children per household, that comes to 108 million homes, presuming there is at least one good child in each. Santa has about 31 hours of Christmas to work with, thanks to the different time zones and the rotation of the earth, assuming east to west (which seems logical). This works out to 967.7 visits per second. This is to say that for each Christian household with a good child, Santa has around 1/1000 th of a second to park the sleigh, hop out, jump down the chimney, fill the stocking, distribute the remaining presents under the tree, eat whatever snacks have been left for him, get back up the chimney, jump into the sleigh and get onto the next house.

Assuming that each of these 108 million stops is evenly distributed around the earth (which, of course, we know to be false, but will accept for the purposes of our calculations), we are now talking about 0.78 miles per household; a total trip of 75.5 million miles, not counting bathroom stops or breaks. This means Santa’s sleigh is moving at 650 miles per second — 3,000 times the speed of sound. For purposes of comparison, the fastest man made vehicle, the Ulysses space probe, moves at a poky 27.4 miles per second, and a conventional reindeer can run (at best) 15 miles per hour.

The payload of the sleigh adds another interesting element. Assuming that each child gets nothing more than a medium sized LEGO set (two pounds), the sleigh is carrying over 500 thousands tons, not counting Santa himself. On land, a conventional reindeer can pull no more than 300 pounds. Even granting that the “flying” reindeer can pull 10 times he normal amount, the job can’t be done with eight or even nine of them—Santa would need 360,000 of them. This increases the payload, not counting the weight of the sleigh, another 54,000 tons, or roughly seven times the weight of the Queen Elizabeth (the ship, not the monarch).

600,000 tons traveling at 650 miles per second creates enormous air resistance – this would heat up the reindeer in the same fashion as a spacecraft reentering the earth’s atmosphere. The lead pair of reindeer would absorb 14.3 quintillion joules of energy per second each. In short, they would burst into flames almost instantaneously, exposing the reindeer behind them and creating deafening sonic booms in their wake. The entire reindeer team would be vaporized within 4.26 thousandths of a second, or right about the time Santa reached the fifth house on his trip.

Not that it matters, however, since Santa, as a result of accelerating from a dead stop to 650 m.p.s. in .001 seconds, would be subjected to acceleration forces of 17,000 g’s. A 250 pound Santa (which seems ludicrously slim) would be pinned to the back of the sleigh by 4,315,015 pounds of force, instantly crushing his bones and organs and reducing him to a quivering blob of pink goo. Therefore, if Santa did exist, he’s dead now.

Merry Christmas.

Now Euler’s my hero
And I see that 0
= e^(i)(pi) + 1

Arguing with an engineer is like wrestling a pig in the mud…

After three hours, you realize the pig likes it.

A plane is travelling from Warsaw to England, when the pilot comes on the PA and says “On the right side of the plane, you can now see a clear view of the English Channel”. Everyone rushes over to look, and the sudden weight shift causes the plane to crash.

The more is too many Poles on the Right Half Plane make the system unstable.

The Surgeon says, “Well, on the seventh day god removed a rib from Addam to create Eve, so God was clearly a surgeon.”

The Engineer says, “Ah, but on the first day God created order out of chaos, so god is an Engineer!”

The Lawyer then grins and say, “But you forget, who do you thing created the chaos?”

A cardiologist died and was given an elaborate funeral. A huge heart covered in flowers stood behind the casket during the service.

Following the eulogy, the heart opened, and the casket rolled inside. The heart then closed, sealing the doctor in the beautiful heart forever.

At that point, one of the mourners burst into laughter. When all eyes stared at him, he said, “I’m sorry, I was just thinking of my own funeral…I’m a gynecologist.”

That’s when the proctologist left.

A smart aleck asks the mathematician “So you are good at math problems, huh?”

The mathematician answers confidendtly, “I like to think I am, yes.”

The kid continues “Ok, well you might need a pencil and paper for this one: your a bus driver, and you pick up seven people ar the first stop. Three of them have blue eyes. Then, at the second stop, four get off, and three get on, one if them has blue eyes. Then, at both the third and fourth stope, 5ive people get on each time, and 4 of those have blue eyets. Then, at the fifth stop, six people get on, 2 with blue yes, and two get off. THen at the seventh stop, three people get off, eight get on, and three of those have blue eyes. So– what color are the bus driver’s eyes?”

The mathematician pauses and says “I can’t determine that from the data you gave me.”

The smart alecik crows “You dummy, you don’t know the color of your own eyes?! The first thing I said was: ‘you’re the bus driver’!”

A physicist, engineer and a statistician are out hunting. Suddenly, a deer appears 50 yards away.

The physicist does some basic ballistic calculations, assuming a vacuum, lifts his rifle to a specific angle, and shoots. The bullet lands 5 yards short.

The engineer adds a fudge factor for air resistance, lifts his rifle slightly higher, and shoots. The bullet lands 5 yards long.

The statistician yells “We got him!”
