name two movies or books in which the number pi plays an important part in the story
Two well-known works where the number π is central to the story are:
- Pi (1998 film, dir. Darren Aronofsky)
- A black‑and‑white psychological thriller about a brilliant but unstable mathematician, Maximillian Cohen, who is obsessed with finding hidden patterns in numbers, especially π.
* He tries to use π and number theory to uncover a formula that explains everything from stock‑market behavior to the structure of the universe, and his discovery of a mysterious 216‑digit number linked to π draws the attention of Wall Street firms and religious mystics.
- Contact (novel by Carl Sagan, film 1997)
- A science‑fiction story in which astronomer Ellie Arroway discovers a signal from an extraterrestrial civilization; in key interpretations of the story, π appears encoded as part of a deeper “hidden message” in the fabric of mathematics itself.
* The use of π here underlines the idea that mathematics—especially universal constants like π—can serve as a common language between intelligent species and as evidence of underlying cosmic design.
