| A beautiful movie...
"The Man Who Knew Infinity" is a Biography - Drama movie in which we watch the true story of the Indian mathematician, Srinivasa Ramanujan. His story starts in Mandras a city in India where he makes his first steps in mathematics while searching for a job and goes until he arrives in Cambridge and starts working there. He faces many difficulties and makes some friendships such as with Professor G.H. Hardy who was also his mentor.

I liked this movie very much because it was a true story of a person who suffered a lot, facing any difficulties but eventually succeeded in his field. The direction which was made by Matt Brown was very good and I believe that the combination he made between the life of Srinivasa Ramanujan in India and what he sacrificed in order to go to England with the life that he was expecting before arriving in England and what he actually lived there was a very good idea. I enjoyed also the interpretation of Dev Patel who played as Srinivasa Ramanujan and for one more time, he was very good at it. Other interpretations that were very good and have to be mentioned are Jeremy Irons who played as Professor G.H. Hardy and Toby Jones who played as Littlewood.

To sum up, I believe that "The Man Who Knew Infinity" is a beautiful movie with a great plot based on an incredible person and pioneer in mathematics. I strongly recommend everyone to watch it because it's a life lesson from which everybody will gain something by watching it. Never stop dreaming and never stop fighting for something you love.

Did You Know?


There are references in the film to "Gunga Din", the poem by Rudyard Kipling. Characters quote 'Din! Din! Din!', a repeated phrase from the poem, and also mention the name, 'Gunga Din'. Ramanujan, like Gunga Din, is an Indian undervalued by his white peers. The key lines from the poem that apply to Ramanujan's situation and his relationships with the Cambridge academics occur in the last verse. The narrator of the poem acknowledges the mistreatment given by himself and the other white men to Gunga Din and the poem finishes with the line, "You're a better man than I am, Gunga Din".


S. Ramanujan: Sir, do you know something I do not?
G.H. Hardy: Apparently not!
G.H. Hardy: Oh! God and I don't exactly see eye-to-eye. So if I prepare for rain, then it won't. So far, so good.
G.H. Hardy: I'm Hardy. And I'm spending the afternoon in the Wren Library!
G.H. Hardy: Now we're sure to have sunshine. ...


When Ramanujan arrives at Trinity College, Littlewood points to a tree and claims that is the tree where Newton got hit in the head by an apple and "invented"/discovered the theory of gravity. It is generally believed that Newton achieved the key insights to develop the Theory of Gravity while Cambridge was closed due to the Great Plague (August of 1665 through March of 1667); so even if the story of the apple were true, it would not have occurred at Trinity College.

Additionally, the tree is called a sapling -- which it clearly is not. Further, if the tree had been there at the time of Newton, then could not be a sapling at the time this event occurred.
