Codebreaker (film)

Codebreaker 2011, original UK title Britains Greatest Codebreaker, is a TV film aired onNovember 2011 by Channelabout the life of Alan Turing. The film had a limited release in the U.S. beginning onOctober 2012. The story is told as discussion between Alan Turing and his psychiatrist Dr. Franz Greenbaum. The story is based on journals maintained by Dr. Franz Greenbaum and others who have studied the life of Alan Turing and also some of his colleagues.

The scene shifts backs to the discussion between Turing and Dr. Greenbaum. Turing speaks about a school friend he was interested in, Christopher Morcom. They were in different houses so they could meet couple of times a week. Turing worked on improving his handwriting because Christopher would make fun of it. Turing goes on to explain that he cared more about what Christopher thought about him than what he thought of himself. Christopher Morcom QC nephew of Christopher Morcom goes on to explain that Christopher and Turing became close friends during their school days. They were planning to join Cambridge University but onFebruary 1930 Christopher died.The scene again shifts backs to the discussion between Turing and Dr. Greenbaum. Turing informs him that he wrote letters to Christophers mother and even managed to acquire his photograph. He still has the photograph in his wallet, and he shows it to Dr. Greenbaum. Turing later goes on to publish his paper On Computable Numbers, with an Application to the Entscheidungsproblem. A computer in those days did not mean a machine, it meant a person who calculates or computes. Turing proposes automating these tasks, proposing universal Turing machine. It involved performing mathematical operation using zeros and ones. This became the basis of modern computers. Steve Wozniak goes on to explain how normal people these days carry and use Turing machines in the form of mobile phones, cameras, computers, etc. Alma Whitten explains that there are almost no fields of modern science and everyday life which are not impacted by Turing machine. ........
