The Complete List

TV Episodes

Still To Locate (Help!)

This page complements our book Mathematics goes to the movies. It contains a list of titles and short descriptions of about 800 movies and TV episodes that contain mathematics. Also included are links to the respective entries in the International Movie Database (IMDB) and links to clips from some of the movies. Titles will continue to be added, and more clips from these movies will be regularly added to our movie clips page.

What's the point? About ten years ago, on a whim, we began to collect movies containing mathematics. Now, as a consequence of that whim, we own a library of more than 800 movies on DVD, VHS, 16 mm, Laserdisc, and some strange thing called a CED video disc. The movies range from those expressly about mathematicians, to those that, for whatever reason, just happen to have a snippet of humorous mathematical dialogue. Over the years, we have found that it is not only professional mathematicians who find the fun in this cinematic mathematics. Just about everybody is charmed by Meg Ryan explaining Zeno's paradox in I.Q., Danny Kaye singing about Pythagoras's theorem in Merry Andrew, Lou Costello explaining to Bud Abbott why 7 x 13 =28 in In the Navy, and so on. Our book is an attempt to identify, organize, and engagingly present this fascinating and funny material.

Some movie math is really, really dull. Even limiting to the good stuff, trying to cram everything in our collection into this one book would have resulted in a bloated, boring mess. However, we did want to be comprehensive, and to make available as much of our source material as possible. We found that the best way to do this was to create this page. Also as we learn of movies, new and old, we will add details to this page. By doing so, we hope to extend our book and to keep it up to date.

Other websites. There are a number of other websites dedicated to mathematics in the movies that you may also want to check out. Most importantly, there is Alex Kasman's Mathematical Fiction Homepage and Oliver Knill's collection of mathematical movie clips (a lot of the links on this page will lead you to this page). For those who read Spanish, there is a huge series of articles by our Spanish doppelgänger, Alfonso Jesús Población. Also make sure to check out, a comprehensive website dedicated to mathematics in The Simpsons. Everything about maths in Futurama can be found in the maths section of the amazing site La indoblable pagina de Bender bending Rodriguez. Also check out some of the websites that talk about the mathematics in the various episodes of the TV series Numb3rs such as Wolfram's Numb3rs website.

Futurama − Ep 6.10: The Prisoner of Benda (2010) IMDB The only TV epsiode ever to have its own theorem. Professor Farnsworth's mind-switching machine can't directly switch the same two minds back into the original bodies. The characters' bodies and minds get hugely tangled, but the Harlem Globetrotters prove that any such tangle can always be inverted using two extra people: "And they say pure maths has no real world applications!" The complete proof is shown. At one point Bender, in Amy's body, has to prove he's a robot, but he fails when he doesn't know the square root of 9: "OK, look, I'm not that kind of robot."

21 (2008) IMDB *** Kevin Spacey is a maths professor who organizes some of his students into a team of blackjack players. The Monty Hall puzzle has a large scene. Newton's method and Fibonacci numbers make brief appearances, and there are some nice blackboards with Cauchy sequences and continued fractions. Clip on our maths clips page. Clip on Oliver Knill's page.

21 Grams (2003) IMDB ** The main character is a mathematician, who engages in "maths is beautiful" philosophizing.

23 (1998) IMDB ** The original German movie, with a guy obsessing on appearances of the number 23: so, 11 + 12 = 23, and so on. The number 5 is also important, since 2+3=5. Clip on Oliver Knill's page.

The 27th Day (1957) IMDB * Some helpful aliens gives doomsday devices to Professor Bechner and others. The Professor deciphers the mathematical symbols − "In mathematics there is always a solution" − ensuring only bad guys are doomed (mostly Russians), and peace reigns.

3:19 Nada es Casualidad (2008) IMDB *** Live action movie with an extended animation sequence on the final days of Évariste Galois.

The 39 Steps (1935) IMDB ** A performing mnemonist memorizes secret mathematical plans.

4D Man (1959) IMDB * "You've compressed the energy of years into a moment." "But ... that's like ... the forth dimension!". Well, maybe not. But the mad scientist being able to pass through solid objects could actually be given a 4D explanation.

The 4th Dimension (2006) IMDB *** Excellent, strange movie about Jack, who is trying to fix time. A few equations, and Einstein makes an appearance. A classroom scene with Jack daydreaming in a geometry lesson. The teacher confronts him and asks him what is the shortest distance between two points. Jack declines to to answer, and then explains that there is no such thing as a straight: a semi-accurate explanation of geodesics and surfaces curving through space. Clip on our maths clips page.

About a Boy (2002) IMDB * Includes a classroom scene in which a teacher talks about the significance of the decimal point.

The Absent-Minded Professor (1961) IMDB * We see the absent-minded professor (not a mathematician) in front of blackboards filled with formulas.

Aces (2006) IMDB ** maths majors, one with the alias "Theorem Girl", spend the summer playing poker. Their probability isn't quite right.

The Accountant (2001) IMDB ** Quirky short film about a very weird accountant who comes to save a family farm. He calculates on his fingers and by stamping his feet: "A man who won't add his own numbers ain't much of a man in my book".

Act Your Age (1949) IMDB ** Unintentionally hilarious morality short. Jim gets frustrated with some simultaneous equations, and starts carving his initials into the school desk. Actually, it's hard to blame him: the equations are 3x+4y+3z =14, 2x+y/2+z=16 and y+3z=6, with solution x=244/33, y=−156/33, z=118/33.

The Adding Machine (1969) IMDB * A counting-obsessed accountant named Zero commits a murder.

A-Ducking They Did Go (1939) IMDB ** The three stooges have a funny 1-liner on percentages.

Alexander the Great (1956) IMDB * Quick 1-liner from young Alexander about learning logic and mathematics at the feet of Aristotle, while his father hogs the glory of conquest.

Agora (2009) IMDB **** Turgid telling of the story of Hypatia. Lots of loony Christians, but not so much maths. Hypatia's father, Theon of Alexandria, appears. There's some conics and some musing over planetary motion, and a good scene where Hypatia draws an ellipse in the sand. This is used as a metaphor, indicating what may have been lost by Hypatia's murder.

Alien Hunter (2003) IMDB *** The main character is an expert cryptanalyst. Very funny blooper involving the chances of something being "99 to the infinite ...", but not 100.

All In (2006) IMDB * A silly poker movie, with a few nonsensical percentages thrown in to make it sound plausible.

Amarcord (1973) IMDB ** A student is at the board, trying to solve 32x2+280x+118 =0. Eventually the teacher helps: her answer is incorrect. Clip on Oliver Knill's page.

Annapolis (2006) IMDB ** Navy recruits learn calculus, and give strange map coordinates: "65 degrees 85 minutes North".

Another Gay Movie (2006) IMDB ** The things we have to watch for this webpage! Andy fantasises having sex during a maths class with his teacher, Mr. Puckov. Averting our eyes, we noticed the surface integrals on the blackboard behind them.

Antonia's Line (1995) IMDB *** A movie about a wunderkind who becomes a mathematician. Wunderkind calculations, and a homological algebra lecture with commuting diagrams on blackboards. Clip on Oliver Knill's page.

Apocalypse Now (1979) IMDB * Dennis Hopper (as the relatively sane one!) tries to explain Marlon Brando to Michael Sheen: "This is dialectics. It's very simple dialectics, one through nine. No maybes, no supposes, no fractions. You can't travel in space, you can't go out into space, you know, without like you know, uh, with fractions. What are you gonna land on? 1/4, 3/8?" Clip on Oliver Knill's page.

Apollo 13 (1995) IMDB * A slide rule appears in one scene, when Mission Control checks Jim Lovell's (Tom Hanks') gimbal angle conversions. Apparently this is not a blooper, despite some such claims. Slide rules are pointless for addition and subtraction, but there is more to the gimbal calcualtions than that. John Llewellyn was the real life slide rule guy, and claims he did use a slide rule for such calculations.

Are You With It? (1948) IMDB **** Donald O'Connor plays Milton Haskins, an actuary who misplaces a decimal point, and despondently quits to become a carny. Some very funny bits, with Milton doing instantaneous calculations with a slide rule. He determines when a poker machine will pay off as "a simple problem in arithmetical progressions ... on the second winning play a combination had been reached, equal to the square root of 322 million raised to the 11th power ... one more play should produce the Johnpot". Milton also explains that "dancing is merely a question of applied mathematics": he demonstrates, with 3 times 2 times 2, leading to a terrific tapdancing routine. Clip on our maths clips page.

The Arrival (1996) IMDB *** Very funny blooper involving an incorrect way to add percentages. Clip on our maths clips page.

Atama-yama (2002) IMDB ** Weird cartoon, culminating with a man having his smaller self sitting on his head, in an infinite descending sequence.

Attack Girls' Swim Team Versus the Undead (2007) IMDB *** Hilarious Z grade horror scene, where the maths teacher turns into a zombie while asking a word problem. Then he starts chopping off limbs using his metal rulers. Clip on our maths clips page.

Au hasard Balthazar (1966) IMDB ** The main character is a donkey. He becomes a circus act, and correctly calculates 834 x 3.

Au Revoir Les Enfants (1987) IMDB *** A teacher discusses the fact that in a quadrilateral circumscribed around a circle, the sum of two opposite sides is equal to the sum of two remaining sides.

Bachelor of Hearts (1958) IMDB *** A sweet comedy about a German student who visits Oxford to study mathematics, and finds beer and romance. He tries to become first wrangler (which is difficult, given he's not at Cambridge). There's some maths around the edges.

Back to the Future Part III (1990) IMDB ** The heroes "think four-dimensionally" in order to drive a locomotive towards a bridge that hasn't been built yet. Clip on Oliver Knill's page.

Ball of Fire (1941) IMDB *** Fun movie about a team of stuffy academics being charmed by Barbara Stanwyck. When Isaac Newton is raised, she refers to herself as just another apple. The mathematician tries to find the common denominator of her syncopated dance moves, and argues from relativity that the signpost ran into their car. The academics argue over whether the correct grammar is "two and two is five", or "two and two are five". They also use Archimede's mirrors idea to thwart the bad guys. Clip on our maths clips page.

The Bank (2001) IMDB ***** A maths prodigy takes revenge on a bank. Tons of maths.

Baraka X−77 (1966) IMDB * The cracking of Professor Sartan's code, and mention of a book "Introduction to the theory of tensor equations".

Battle of the Worlds (Il Pianeta Degli Uomini Spenti) (1961) IMDB *** Crazy mathematician does calculus on flowerpots. Pythagoras's harmony of the spheres gets a mention.

A Beautiful Mind (2001) IMDB ***** An excellent movie about the brilliant mathematician John Nash, who won the Nobel Prize in economics for his work in game theory. Clip on Oliver Knill's page.

Beautiful Ohio (2006) IMDB **** Excellent, dark movie about a maths prodigy and his family, seen through the eyes of his less brilliant brother. "Square root of 56 389". "237 point, about 46". "That truly is extraodinary. Where do you get that from?" "From the back of the sock drawer". Maths scattered throughout, including the famous weighing puzzle of 12 coins containing a counterfeit.

Bedazzled (1967) IMDB *** Peter Cook, as the devil, explains to Dudley Moore that everything he's ever said to him is a lie. A very funny display of the Liar's Paradox. Clip on Oliver Knill's page.

The Belly of an Architect (1987) IMDB * Nice scene in which the main character of the movie discusses the portrait of Isaac Newton on an old British 1 pound note.

The Best of Youth (La Meglio Gioventù) (2003) IMDB ** Giulia explains that she started studying maths because she wanted to solve the problem of the jealous husbands: three couples want to cross the river in a boat which only holds two people, and each jealous husband refuses to have his wife left with other men. Giulia's audience doesn't get very far with the solution.

Better Off Dead (1985) IMDB *** A comedy in which a maths teacher doing really boring and nonsensical maths is worshipped by his students. Clip on our maths clips page.

And a dumb blonde recalls a formula: "It started with a capital N, and then there was a little A, followed by a 3. Ah, then there was a squiggle above a tick, and ah ... a hot cross bun sign." Clips on our maths clips page.

Butterfly Dreaming (2008) IMDB *** A stylish dream-or-reality movie, where the main character, Rob, is a mathematics professor. There's a couple fleeting references to homomorphisms and stable homotopies, and a very nice image of cycloids, made by following the reflectors on bicycle wheels. There's also a blooper where Rob estimates the number of leaves on a tree by imagining 12 branchings, and then 212 is supposedly about 8000. Clip on Oliver Knill's page

Cabiria (1914) IMDB *** The earliest movie we know of containing maths. Archimedes uses a compass (?) to design his ship-burning mirrors. Clip on our maths clips page.

Calabuch (1956) IMDB ** Some singing of times tables, and a retired physicist writes some equations on a wall.

Carreteras Secundarias (Backroads) (1997) IMDB * In a failed attempt to keep him from his father's criminal ways, Felipe is provided with a tutor: "OK, again. The derivative of the function at x is the tangent of the curve at the given point. ... it's very easy, it's just you don't pay attention. The tangent and derivative are the same." Felipe punches the tutor in the nose.

Carry on Teacher (1959) IMDB ** A smug supervisor interrupts maths class, to test how kids react to him noting down two-digit numbers with the two digits reversed. Ends with a kid asking him to write down 33. Clip on our maths clips page.

Cartesius (1974) (TV) IMDB *** More philosophy than maths in Roberto Rossellini's biopic. One extended scene has Descartes solving a gravitational problem posed by the mathematician Isaac Beeckman. The mathematician Marin Mersenne makes a brief appearance.

Casino Royale (2006) IMDB * M describes the villain Le Chiffre as a mathematical prodigy. Bond apparently isn't: he declares Le Chiffre had a 23 to 1 chance of the river card turning his two pair into a full house. The correct odds are 10.5 to 1. Clip on Oliver Knill's page.

Cast Away (2000) IMDB ** Tom Hanks calculates the size of the circular area that his rescuers will have to search. Clip on Oliver Knill's page.

Saint Clara (Clara Hakedosha) (1996) IMDB *** Clara twice correctly predicts which 5 questions out of 1000 the mathematics teacher will set on the test. The teacher tries to explain to Clara's parents the unlikelihood of this, by giving the famous example about doubling the grains of rice on the squares of a chess board. Clara's father shows how to divide a cake into seven equal pieces: he divides it into 8 pieces and throws the eighth piece away. Later, the teacher assigns Clara an "impossible problem", √(2-x2) = 4, and all Hell breaks loose.

Class Action (1991) IMDB * An actuarial beancounter shows why it is cheaper to deal with law suits than to fix a deadly fault in some cars.

    A 3 is all that's good and right. Why must my 3 keep out of sight
    Beneath a vicious square root sign? I wish instead I were a 9.
    For 9 could thwart this evil trick with just some quick arithmetic.
    I know I'll never see the sun as 1.7321.
    Such is my reality, a sad irrationality.
    When Hark!, what is this I see? Another square root of a three
    Has quietly come waltzing by. Together now we multiply
    To form a number we prefer, rejoicing as an integer.
    We break free from our mortal bonds, and with a wave of magic wands
    Our square root signs become unglued, and love for me has been renewed.

The only maths is in the first episode, where Stephen explains his research to Andrew and Brian, owners of the company Inquirendo: "... let Ric be the Ricci curvature, and the gammas are the Christoffel symbols. The idea is to show that under the Ricci flow, positive curvature tends to spread outwards, uh, until at infinite time, the manifold will achieve constant curvature. Now let us consider a generalization of this, the form F is a nice, smooth function. Even in this state the flow will develop singularities in finite time. But, by using a local version of the Gromov compactness theorem, I've been able to get a model of all possible singularities ..." This is actually real mathematics, underlying Perelman's proof of the Poincaré conjecture. Andrew tries to explain the importance of Stephen's reasarch to Brian, a non-mathematician, that it has to do with "topology ... rubber sheet geometry" and "the shape of the Universe". Brian doesn't follow very well: "I thought it had something to do with killer bees". Clip on Oliver Knill's page

Figuring the average is 4 marks a day and there are 300,000 of them, how much would the state save if these individuals were simply eliminated?" "Completely unbelievable!" "That is exactly how I reacted." "Completely unbelievable. I can't believe an elementary school child is expected to solve something like this. It's a difficult calculation, the proportions, the percentages, they need some algebra to solve these equations, right? That would be highschool material for us." "No, no, it's just multiplication, what did you say it was, 300,000 cripples?" "Yes." "300,000 times four. We'd be saving about 1,200,000 marks a day if we killed them all. It's easy."

Futurama: Bender's Big Score (2007) IMDB *** The Harlem Globetrotters use their "razzle-dazzle globetrotter calculus" (variation of parameters and expansion of the Wronskian) to prove the possiblity of paradox-free time travel: "Man, that cube root was a real buzzer beater, Clyde".

Futurama: The Beast With a Billion Backs (2008) IMDB *** Very funny Flatland scene in the 2D Tunnel of Love: "Wow! You even look beautiful in 2D." "I do?

Futurama − Ep 6.3: Attack of the Killer App (2010) ** IMDB Fry and Bender each have a million followers on their Twitcher accounts, so Mom concludes she can download a twitworm to their eye-phones to create two million zombies. Her son Walt corrects her, to conclude that "all we can say for sure is that there will be between one million and two million zombies". Mom whacks him.

Futurama − Ep 6.5: The Duh-Vinci Code (2010) *** IMDB Hilarious spoof of The Da Vinci Code. Dan Brown's book is one of the ancient texts: "... Some preposterous hogwash about the Fibonacci sequence ...". It turns out that Leonardo was an alien, too stupid to make it on his own Planet Vinci. Professor Farnsworth attends a calculus lecture, where all the answers have to be in the form of an opera; the lectures includes the Riemann Zeta function, and ellipses and linear transformations. Later, the humiliated Professor advocates using Leonardo's doomsday machine to "kill them all, starting with the maths teacher". There's also a maths museum in the form of the fifteen puzzle.

Futurama − Ep 6.6: Lethal Inspection (2010) *** IMDB Hermes and Bender search for Inspector 5, and confront a huge cube of administrator cubicles: "Wow. Until now I thought giant cubes were exciting." It turns out to work like a 4-dimensional Rubik's cube. They can't find any record of Inspector 5. "Maybe if I kick the ass of Inspector 2 plus Inspector 3 ..." "Addition never solved anything, Man!".

Futurama − Ep 6.10: The Prisoner of Benda (2010) ***** IMDB The only TV epsiode ever to have its own theorem. Professor Farnsworth's mind-switching machine can't directly switch the same two minds back into the original bodies. The characters' bodies and minds get hugely tangled, but the Harlem Globetrotters prove that any such tangle can always be inverted using two extra people: "And they say pure maths has no real world applications!" The complete proof is shown. At one point Bender, in Amy's body, has to prove he's a robot, but he fails when he doesn't know the square root of 9: "OK, look, I'm not that kind of robot."

Malcolm in the Middle − Ep 1.8: Krelboyne Picnic (2000) IMDB **** The Krelboyne class are the entertainment at a picnic. Malcolm performs some impressive mental arithmetic, but the other acts are less gripping. "Our next act needs no introduction, having been the buzz of last year's maths fair. Please welcome Flora Mayesh, and Fermat's Last Theorem!! ... hello, is this, testing ..."

Malcolm in the Middle − Ep 1.13: Rollerskates (2000) IMDB *** Malcolm is carefully making a fair division of the french fries, and Reese and Dewey object. "This isn't fair!" "Yes, it is. It's absolutely fair." "I'm getting hungry." "We're doing it my way." "They're getting cold." "You want them divided up fairly or not?" "You have more than me." "No I don't. We all have 29 inches of fries so far. I have two 4-inchers, five 3-inchers and three 2-inchers. You have five 5-inchers and a 4-incher ..."

Meet Corliss Archer − Ep 1.6: The Algebra Problem (1954) IMDB **** Remarkable episode, completely taken up with people trying to solve Corliss's "algebra" homework problem: "There are 17 prisoners in a jail, and there are 9 policemen in the courthouse, but they have one police car that holds 6 people, including the driver, and only a policeman can drive it. At no time can there be more prisoners than policemen, in the courthouse, in the jail, or in the car. The policemen have to bring the prisoners to the courthouse... How can all the prisoners be moved in 5 round trips?" The problem is impossible for a number of simple reasons, but no one seems to notice.

IMDB *** Boris as Art Looklater asks Bullwinkle a fake quiz question: "Tell me, do you know Plank's constant of quantum mathematics?" "No". "That's right! No, you don't. Congratulations!" This allows Bullwinkle to buy the Kirward Derby, and he tries it on. "Say, it fits like a dream". "Yeah, and the square of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the two sides".

Rocky and Bullwinkle − Ep 3.24: Boomerang Bowler or Boris Makes a Comeback (1961?) IMDB *** Bullwinkle puts on the Kirward Derby, to figure out when the train will get them to Washington. "Easy.

Tae-Woong makes progress on his primes problem by pondering an array of colored boxing gloves. Unfortunately, he seems to be also be referring to a book called Mathematics for Economists. The Professor complains that it will be hard to get Tae-Woong's work refereed, becuase number theorists don't know ergodic theory and vice versa.

The Snow Queen − Ep 16 (2007) ** Three years later, Tae-Woong returns from America a Doctor and having won the Fulkerson Prize. He gives a lecture on his work.

The jockish Lieutenant Ford refuses to play along: "This is some sort of payback for guys like me beating up guys like you in high school, right?"

Stargate: Atlantis − Ep 4.6: Tabula Rasa (2007) IMDB *** A bacterium is causing memory loss in the crew, and McKay is really worried because his memory was always lousy: "I once forgot Mother's Day five years in a row". "What's the ratio of a circle's circumference to its diameter?" "Well that's pi. It's three point one four one five nine two six five etcetera etcetera. That doesn't count: that's easy".

Still Standing − Ep 2.14: Still Bill's Dad (2004) IMDB ** Brian's macho grandfather is not impressed by Brian participating in the maths Olympics: "You want a bow and arrow, in case one of them refs makes a bad call?" The actual quiz problems don't seem to make much sense.

Taken − Ep 1.3: High Hopes (2002) IMDB *** The mother of some kids doing algebra isn't coping very well with real life: "My best subject in school was algebra. People always say algebra's hard, but that is because they don't get how easy it is. I just loved all those X's. Anything you don't know, you just put down an X, or you can go with Y's, or A's and B's. In real life you have 1 plus 1, and if it doesn't equal 2, you're up a creek. But in algebra it always works, no matter what the answer is. You just have to figure out what X is."

Taken − Ep 1.7: God's Equation (2002) IMDB *** It turns out God's equation is the Fibonacci sequence: "writ large across the Heavens". This coming from two guys who just exploded a hamster. These same guys are trying to use Fibonacci numbers to track the aliens: apparently there are 55 breeding pairs, 46368 aliens in total, and so on. Fibonacci numbers are briefly mentioned again in Episode 9, where people are trying to figure out the alien language.

The Tenant of Wildfell − Ep 1 (1996) IMDB ** Judging distances for painting, by "a combination of geometry and experience". "Surely mathematics has no place on the moors." Clip on Oliver Knill's page.

Threshold (2005 − 2006) IMDB *** This shortlived TV series contains the very funny character, Ramsey: a sarcastic dwarf mathematician, who likes to hang out in strip joints.

Threshold − Ep 1.1: Trees Made of Glass, 1 (2005) IMDB *** A four-dimensional alien object intersects our world and drives people insane. Nice graphics.

Threshold − Ep 1.2: Trees Made of Glass, 2 (2005) IMDB *** The mathematician Ramsey refers to isomorphic group therapy (!), monotonic null-sequences, and quadratic reciprocity.

Threshold − Ep 1.11: Outbreak (2006) IMDB *** The mathematician Ramsey is "determining the corresponding probability characteristics of a system of random variables" (by asking people in a market how many tomatoes they just bought and how many people make up their family.)

Thunderbirds − Ep 1.11: Sun Probe (1965) IMDB *** "Now, Brainman, I want you to calculate the following equation. What is the square root to the power of 29 of the trigonometric amplitude of 87 divided the quantative hydraxis of 956 to the power of 77." The answer is apparently 45969.

Torchwood − Ep 1.12: Captain Jack Harkness (2007) IMDB *** Toshiko (the "mathematician") and Jack are trapped in a dance hall in the 1940's. Their return to the present day depends upon some critical formulas. The formulas are actually elementary trig integrals. These formulas also get garbled from scene to scene, and at some point the differential dx becomes cx.

The Twilight Zone: From Agnes With Love − Ep 5.20 (1964) IMDB *** Agnes is an erratic, jealous computer. Elwood checks her out by asking for "the first prime number larger than the 17th root of 9 000 355 126 606". Agnes "correctly" gives the answer as "five", when in fact the answer is 7. Agnes's answer would have actually been correct if Elwood had asked for 9 billion instead of 9 trillion.

The Twilight Zone: I of Newton − Ep 1.12, New Series (1985) IMDB ***** "I'd sell my soul to get this right", exclaims a frustrated mathematician. The devil promptly appears to accept the trade.

Twin Peaks − Ep 1.5 (1990) IMDB ** The sexy Audrey Horne correctly sums up the situation: "I've been doing some research. In real life, there is no algebra."

Two Pints of Lager and a Packet of Crisps − Ep 8.4: Ello Ello (2009) IMDB ** Louis is trying to teach her 10 week old baby: "Now, what is the square on the hypotenuse equal to? ... No, it isn't spit-bubble you oaf!". Later, she bemoans the fact that her baby can't even grasp the basics of mathematical philosophy.

Two and Half Men − Ep 6.5: A Jock Strap in Hell (2009) IMDB ** Jake is tutored by his ex-teacher, now a sexy dancer. They discuss algebra with reference to dancing and tips, and the house's cut ("the constant").

The Two Ronnies (1986) IMDB *** "And in a packed program tonight, we shall be talking to a Catholic lumberjack and his mathematician bride to be, who plan to use the Logarhythm method."

Weeds − Ep 1.12: Higher Education (2005) IMDB ** Sanjay is a maths tutor, whose tutee finds "what percentage is 12 of 75?" too much to handle.

The West Wing − Ep 1.17: The White House Pro-Am (2000) IMDB ** Silly but well-written fluff, designed to make American Democrats feel good about themselves. But, at least this episode has a very funny conversation between the president and her daughter, about her not taking maths at college.

The West Wing − Ep 1.18: Six Meetings Before Lunch (2000) IMDB ** Funny conversation about reparations for slavery, multiplying the number of slaves, by the number of hours worked, by the market value of the labor, arriving at "a very conservative figure". "What is it?" "$1.7 trillion." "... OK ... this is probably a better discussion to have in the abstract."

The West Wing − Ep 2.3: The Midterms (2000) IMDB ** Some pretty funny banter about "acalculia".

The West Wing − Ep 4.1: 20 Hours in America (2002) IMDB ** A discussion of chaos theory, and its relation to the craziness of campaigning.

The Wire (2002 − 2008) IMDB *** In the fourth season, Prez has been forced out of the Baltimore police force, beginning a new career as a maths teacher in a poor black school. Prez begins very awkwardly, but throughout the season develops an increasing rapport with his students. Somewhat reminiscent of Stand and Deliver.

The Wire − Ep 4.3: Home Rooms (2006) IMDB *** The episode is punctuated by Prez's fruitless efforts to get his students in interested in a word problem. "So, my question for you is [the bell rings to end class, and the students start banging out of the room] ... A, Who arrived in Philly first, Andre or Yvonne? ... And B, by how much time? [the room is now empty] ... And C, who gives a rat's ass?"

The Wire − Ep 4.7: Unto Others (2006) IMDB *** Prez notices his students playing poker very badly. He starts teaching them simple probabilities of cards and dice. In the later episode Know Your Place, two students want Mr. P to order candy over the internet for them to resell. He demands the cash upfront. They bring in the cash, explaining they won it in a corner crap game: "6 beats 4 or 5, and most times 8 is better than 10, right. You schoolin' me good! ..." "You shouldn't gamble." "I know. But I'm just sayin', maths be right, Mr. P".

A Very Peculiar Practice (1986 − 1988) IMDB *** The main character is Stephen Daker, the new GP at a university. In the first season, his flatmate is a quirky Burmese mathematician named Chen. The flat is full of blackboards, and there are a number of scenes of a happy Chen calculating away. Mostly matrix and tensor algebra.

A Very Peculiar Practice − Ep 1.3: Wives of Great Men (1986) IMDB *** Daker comes home, sees the blackboards covered with Chen's calculations, and comments on his good day's work. Chen explains otherwise: "This is a bad day's work! On a good day, maybe one line, but a good one. Same with poetry".

A Very Peculiar Practice − Ep 1.7: Catastrophe Theory (1986) IMDB *** In the final episode of the season, all Hell is breaking loose. As a metaphoric subplot, Chen has his work on catastrophe theory stolen by a fellow mathematician.

Weird Al Yankovic: I Lost on Jeopardy (1984) (Music Video) ** Parody of the gameshow, to the tune of My Life's in Jeopardy. Weird Al chooses Potpourri for 100, and has to supply the question for which the answer is the Lorentz equations.

Weird Al Yankovic: Jurassic Park (1993) (Music Video) ** Very funny parody to the tune of Macarthur Park. References to Jeff Goldblum's mathematician character: "I admit it's kinda eerie, but it proves my chaos theory ..."

Weird Al Yankovic: White & Nerdy (2006) (Music Video) *** Parody of the rap song Ridin' (Dirty): "MC Escher is my favorite MC ... Yo I know pi to a thousand places ... Do vector calculus just for fun". It appears that the first 1000 digits of π are correctly displayed.

Without a Trace: Claus and Effect − Ep 6.10 (2007) IMDB *** Glen is a brilliant maths grad, who gives it up to play Santa and blackjack.

Wonder Woman: The Pluto File − Ep 1.8 (1976) IMDB *** Professor Warren uses the harmonic equation and other PDE's to create earthquakes. He then struggles to figure out how to stop them, with Wonder Woman's help: "Integral calculus is always problematical", at which point she shows the Professor the critical substitutions. Clip on our maths clips page.

The Wonder Years − Ep 3.2: maths Class (1989) IMDB **** Kevin has a tough new maths class with Mr. Collins, a terrific character. Lots of algebra, fractions, absolute values and so on. A couple bloopers: the union and intersection of a Venn diagram are interchanged and the Venn diagram changes mid-scene; and, what are clearly meant to be the integers are labelled the rational numbers.

The Wonder Years − Ep 3.9: maths Class Squared (1989) IMDB *** Mr. Collins is back. Some cheaters claim he lives on "Planet Pythagoras". Some completing the square and so on. Mr. Collins (correctly) solves the equation √x + 3 = x + 1. There's a strange dream sequence when Kevin cheats himself into Mr. Collins' advanced maths class, ending in a Twilight Zone scenario.

The Wonder Years − Ep 3.20: Goodbye (1990) IMDB **** The last episode with Mr. Collins. The division of 6x2 + 2y2 + 7xy + 7y +3 by 3x + 2x. A terrific episode on the power of teaching.

Yakitate!! Japan − Ep 1.40 (2005) IMDB *** Pierrot sets the number 104 877 443 673 as a puzzle to decode, as a delaying tactic. But Azuma calculates almost immediately that the answer is Mamadoko: where's Mama. She notes that the number written in base 26 is (13,1,13,1,4,15,11,15), with each base 26 "digit" standing for a letter of the alphabet. Clip on Oliver Knill's page.

The X Files − Ep 1.22: Roland (1994) IMDB *** Roland is an idiot savant, who corrects scientists' fluid dynamics equations when he's not killing them.

The X Files − Ep 3.11: Revelations (1995) IMDB ** The teacher calls Kevin to the blackboard to divide 11 into 170. He writes up the problem, but then his hands start bleeding with the signs of stigmata.

The X Files − Ep 7.17: All Things (2000) IMDB *** Mulder wants to investigate fractal-like crop circles, the appearance of the Mandelbrot set et al. Scully is sceptical: "... I'm not interested in tracking down some sneaky farmers who happened to ace geometry in high school".
