I recently watched a film called “The Man Who Knew Infinity” and highly recommend it. It is about Srinivasa Ramanujan, an incredible mathematician. I was using Ramanujan’s formula in my final exam for economics yesterday. There is a wonderful quote in the script, not sure who coined it, but it is said by the character Littlewood to Ramanujan - “Great knowledge comes from the humblest of origins”, then Littlewood points to Newton’s tree on the campus - “apple fell on his head”:) 🍏 the film captures where Ramanujan originally wrote his formulas - it so pure.
