Five Math Movies That Actually Happened

John Nash published his doctoral dissertation in 1950. It was 28 pages long. In it, he introduced what is now called the Nash equilibrium — a concept that would eventually reshape economics, political science, evolutionary biology, and the theory of auctions. The Nobel Committee awarded him the Prize in Economics in 1994, forty-four years later.

Ron Howard’s film focuses less on the mathematics and more on Nash’s decades-long struggle with paranoid schizophrenia. This is a fair editorial choice. The equilibrium concept is genuinely difficult to dramatize. What is not difficult to dramatize is a man arguing with people who are not there. The film does both jobs, in that order of priority.

Russell Crowe’s performance received an Academy Award nomination. The film won Best Picture. More importantly, it introduced Nash equilibrium to an audience of millions who have since used it, knowingly or not, in every negotiation they have ever entered.

In 1982, eighteen students at Garfield High School in East Los Angeles — a school the state had threatened to strip of its accreditation — passed the Advanced Placement Calculus exam. The Educational Testing Service found the scores suspicious and asked the students to retake it. They did. They passed again. The accusation was not based on any specific evidence of cheating. It was based on the assumption that these students, from this neighborhood, could not have done what they demonstrably did.

Jaime Escalante had given up a career as an engineer in Bolivia to become a teacher in the United States. By 1987, his program had grown to 73 AP Calculus students — more than any comparable public school in the country. By 1991, Garfield had become one of the highest AP Calculus testing schools in the nation.

The film is not subtle. It does not pretend to be. It was made to be shown in classrooms, and it has been, for nearly four decades.

Katherine Johnson calculated the trajectory for Alan Shepard’s 1961 suborbital flight. She calculated the trajectory for John Glenn’s 1962 orbital flight. Glenn himself, before boarding Friendship 7, asked NASA to have “the girl” — meaning Johnson — manually verify the IBM 7090’s calculations before he would agree to launch. The computer had already done the math. Glenn wanted the human to check it. The human was Katherine Johnson.

Dorothy Vaughan became NASA’s first Black supervisor in 1949. Mary Jackson became NASA’s first Black female engineer in 1958. These are not minor footnotes. They are foundational contributions to one of the most documented engineering programs in history, which somehow managed to go largely unacknowledged for fifty years.

The film earned three Academy Award nominations, including Best Picture. More usefully, it restored three names to the historical record they had always belonged in.

In 2002, the Oakland Athletics had a payroll of $41 million. The New York Yankees had $125 million. Oakland finished with a 103-win season and a 20-game winning streak. They did it by replacing the scouts’ intuition with on-base percentage, slugging percentage, and the insight that baseball had been systematically mispricing certain statistics for a century.

The mathematics here is not glamorous. It is spreadsheet mathematics — regressions, OBP calculations, market inefficiency analysis. Paul DePodesta, whose character is renamed in the film, had a degree in economics from Harvard. He was not making stunning breakthroughs in abstract algebra. He was reading the numbers that everyone else had and reaching different conclusions about what they meant.

Six Academy Award nominations. Brad Pitt has never been better at playing someone who is doing math.

Morgan Matthews made a documentary called Beautiful Young Minds in 2007, following the British team preparing for the International Mathematical Olympiad. One of the students in that documentary, Daniel Lightwing, was autistic, exceptionally gifted, and — as the film showed without editorializing — deeply isolated in ways that had nothing to do with his mathematical ability. Matthews later returned to that material and turned it into a fiction film, with Asa Butterfield in the lead role.

The IMO problems shown in the film are real. The training process is accurate. The competitive pressure — 100 countries, six problems over two days, scores that can determine university placement and funding — is not invented for dramatic effect.

X+Y is quieter than the others on this list. It does not have an obvious villain, a courtroom scene, or a moment where someone proves something on a blackboard while violins play. It is a film about what it is like to be excellent at the one thing that makes you feel real, in a world that keeps asking you to be better at everything else.
