Posts Tagged ‘The Man Who Knew Infinity – movie review’

Today’s reviews are for a pair of biographical movies about two geniuses.  The men are Srinivasa Ramanujan and Alan Turing.  Technically, both are mathematicians, but Turing is more remembered for his work with computers.  The two movies are titled:  “The Man Who Knew Infinity” (2015) about Ramanujan, and “The Imitation Game” (2014) about Turing.
The Man Who Knew Infinity” (2015)  —  movie review
This movie stars Dev Patel as Indian mathematician Srinivasa Ramanujan and Jeremy Irons as his British mentor (collaborator) G. H. Hardy.  Basically, a poor, self-taught mathematician moves to Trinity College at Cambridge after mailing some of his work to a world famous mathematics professor (Hardy).  The two collaborate (and publish), but the movie is basically about their personal relationship and not about their maths.  The movie is beautifully shot in both India and England and I was moved by the depictions of both environments:  brightly colored poverty contrasted with muted earth-toned (relative) wealth.  A second major plot contrast is Hardy’s atheism vs Ramanujan’s devout Hindu faith.   Ramanujan tells Hardy that his math comes from the lips of his god.  Hardy can only struggle to understand divine inspiration.  In the end, Hardy accepts that his friend believes it is true even if he cannot share that belief.
Final recommendation:  highly recommended and I look forward to reading the book (of the same title) the movie is based on.
The Imitation Game” (2014)   —  movie review
This movie stars  Benedict Cumberbatch (aka Sherlock Holmes / Doctor Strange) as Alan Turing and  Keira Knightley as Joan Clarke who was Turing’s fiancé briefly.  Turing was a homosexual and at that time, being gay was considered a serious crime in England.  Both Turing and Clarke were mathematicians who became cryptologists.  They famously developed a computer which was used to break the Nazi Enigma cypher.   This movie describes this invention and Turing’s subsequent suicide.   As a personal note: I consider Turing to be one of the seminal figures in computer science and in artificial intelligence.  The “test” for general purpose artificial intelligence is named “The Turing Test” and based on one of his papers.
Turing and Clarke worked closely together and are reported to have actually been very close friends although I’ve seen Turing portrayed as almost autistic in dealing with social settings, so I’m not sure how accurate the descriptions or the portrayals have been.  In any case, Turing proposed marriage to Clarke and then later withdrew and admitted to being gay.  The movie purports to Clarke being indifferent to Turing’s sexuality as she is contented with having a relationship with a friend and an intellectual equal.
The “surprise” hack at the end of the movie is the realization that the Nazi messages all end the same and this can be used as a key to reduce the number of variations the computer needs to evaluate.  Whether this is what actually happened or not, I don’t know, but it did make for a plausible ending!  Final recommendation:  highly recommended!
While I enjoyed both movies I would rate “Infinity” slightly higher than “Imitation”.  I’m not really sure why, but I’ve already re-watched “Infinity” twice and I’m just getting around to my second viewing of “Imitation”.  But, again, both highly recommended…
