You&#x27;re absolutely right. But the movie is not meant to be a documentary about the math, it is meant to be a story about his life. The same goes for Theory of Everything, Imitation Game, and A Beautiful Mind. The different here is that what math they show is actually correct.<p>I was also disappointed that the discussion afterwards put so much emphasis on him as a person, and not on the actual math, but I don&#x27;t hold that against the film itself. Movies about artists and authors have never been about their works of art either: the movies are about their lives, and I think it is appropriate for cinema to be used as a medium for biography rather than as a medium for education.
