Young Alan Turing Jack Bannon Edit Storyline Based on the real life story of legendary cryptanalyst Alan Turing, the film portrays the nail-biting race against time by Turing and his brilliant team of code-breakers at Britain's top-secret Government Code and Cypher School at Bletchley Park, during the darkest days of World War II.
Edit Did You Know? Trivia At the interrogatory scene, Turing describes the famous "Turing Test". In the original illustrative example, a human judge engages in natural language conversations with a human and a machine designed to generate performance indistinguishable from that of a human being.
The conversation is limited to a text-only channel such as a computer keyboard and screen so that the result is not dependent on the machine's ability to render words into audio.
All participants are separated from one another. If the judge cannot reliably tell the machine from the human, the machine is said to have passed the test.
The test does not check the ability to give the correct answer to questions; it checks how closely each answer resembles the answer a human would give.
The test was introduced by Alan Turing in his paper "Computing Machinery and Intelligence," which he asks, "Are there imaginable digital computers which would do well in the imitation game?
More than 50 years later, no computer could pass the test. Goofs When the code breakers break their first message on the Bombe, Hugh Alexander reads out the German submarine position as 53 degrees 24 minutes North, 1 degree West.

For three years at least, as we know from his letters to Morcom's mother, his thoughts turned to the question of how the human mind, and Christopher's mind in particular, was embodied in matter; and whether accordingly it could be released from matter by death.
This question led him deeper into the area of twentieth century physics, first helped by A. Eddington's book The Nature of the Physical World, wondering whether quantum-mechanical theory affected the traditional problem of mind and matter.
As an undergraduate at King's College, Cambridge from , he entered a world more encouraging to free-ranging thought. His reading of the then new work of von Neumann on the logical foundations of quantum mechanics, helped the transition from emotional to rigorous intellectual enquiry.
At the same time, this was when his homosexuality became a definitive part of his identity. The special ambience of King's College gave him a first real home.
His association with the so-called anti-War movement of did not develop into Marxism, nor into the pacifism of his friend and occasional lover James Atkins, then a fellow undergraduate mathematician, later musician.
He was closer in thought to the liberal-left economists J. Keynes and A. His relaxations were found not in the literary circles generally associated with the King's College homosexual milieu, but in rowing, running, and later in sailing a small boat.
Turing's progress seemed assured, A distinguished degree in followed by a Fellowship of King's College in and a Smith's Prize in for work on probability theory, and he might then have seemed on course for a successful career as a mildly eccentric King's don engaged in pure mathematics.
His uniqueness of mind, however, drove him in a direction none could have foreseen. By Turing had already introduced himself to Russell and Whitehead's Principia Mathematica and so to the then arcane area of mathematical logic.
Bertrand Russell had thought of logic as a solid foundation for mathematical truth, but many questions had since been raised about how truth could be captured by any formalism.
In particular, in Gödel had shattered Russell's picture by showing the incompleteness of mathematics: the existence of true statements about numbers which could not be proved by the formal application of set rules of deduction.
In , Turing learnt from the lecture course of the Cambridge topologist M. Newman that a further question, posed by Hilbert, still lay open.
It was the question of Decidability, the Entscheidungsproblem. Could there exist, at least in principle, a definite method or process by which it could be decided whether any given mathematical assertion was provable?
To answer such a question needed a definition of 'method' which would be not only precise but compelling. This is what Turing supplied.
He analysed what could be achieved by a person performing a methodical process, and seizing on the idea of something done 'mechanically', expressed the analysis in terms of a theoretical machine able to perform certain precisely defined elementary operations on symbols on paper tape.
He presented convincing arguments that the scope of such a machine was sufficient to encompass everything that would count as a 'definite method.
In April he showed his result to Newman; but at the same moment the parallel conclusion of the American logician Alonzo Church became known, and Turing was robbed of the full reward for his originality.
His paper, On Computable Numbers with an application to the Entscheidungsproblem, had to refer to Church's work, and was delayed until August However it was seen at the time that Turing's approach was original and different; Church relied upon an assumption internal to mathematics, rather than appealing to operations that could actually be done by real things or people in the physical world.
Subsequently, the concept of the Turing machine has become the foundation of the modern theory of computation and computability.
Turing worked in isolation from the powerful school of logical theory centred on Church at Princeton University, and his work emerged as that of a complete outsider.
One can only speculate, but it looks as if Turing found in the concept of the Turing machine something that would satisfy the fascination with the problem of Mind that Christopher Morcom had sparked; his total originality lay in seeing the relevance of mathematical logic to a problem originally seen as one of physics.
In this paper, as in so many aspects of his life, Turing made a bridge between the logical and the physical worlds, thought and action, which crossed conventional boundaries.
His work introduced a concept of immense practical significance: the idea of the Universal Turing Machine. The concept of 'the Turing machine' is like that of 'the formula' or 'the equation'; there is an infinity of possible Turing machines, each corresponding to a different 'definite method' or algorithm.
But imagine, as Turing did, each particular algorithm written out as a set of instructions in a standard form. Then the work of interpreting the instructions and carrying them out is itself a mechanical process, and so can itself be embodied in a particular Turing machine, namely the Universal Turing machine.
A Universal Turing machine can be made do what any other particular Turing machine would do, by supplying it with the standard form describing that Turing machine.
One machine, for all possible tasks. It is hard now not to think of a Turing machine as a computer program, and the mechanical task of interpreting and obeying the program as what the computer itself does.
Thus, the Universal Turing Machine embodies the essential principle of the computer: a single machine which can be turned to any well-defined task by being supplied with the appropriate program.
Additionally, the abstract Universal Turing Machine naturally exploits what was later seen as the 'stored program' concept essential to the modern computer: it embodies the crucial twentieth-century insight that symbols representing instructions are no different in kind from symbols representing numbers.
But computers, in this modern sense, did not exist in Turing created these concepts out of his mathematical imagination.
Only nine years later would electronic technology be tried and tested sufficiently to make it practical to transfer the logic of his ideas into actual engineering.
In the meanwhile the idea lived only in his mind. In common with other outstanding young scientists, Turing spent two years at Princeton University enrolled as a graduate student.
He arrived in September On Computable Numbers But Turing certainly did not shoot to fame. He worked on on algebra and number theory; on showing that his definition of computability coincided with that of Church; and on an extension of his ideas Ordinal Logics which provided a Ph.
The work on 'ordinal logics', probably his most difficult and deepest mathematical work, was an attempt to bring some kind of order to the realm of the uncomputable.
This also was connected to the question of the nature of mind, as Turing's interpretation of his ideas suggested that human 'intuition' could correspond to uncomputable steps in an argument.
But Turing never pursued this line of development after Instead, he was increasingly preoccupied with more immediate problems which demanded logical skills.
True to the concreteness of the Turing machine, he also spent time at Princeton making a cipher machine based on using electromagnetic relays to multiply binary numbers.
Even then he saw a link from 'useless' logic to practical computation. Although not one of the political intellectuals of the s, Turing followed current events and was influenced in studying ciphers by the prospect of war with Germany.
In Turing was offered a temporary post at Princeton by von Neumann but instead returned to Cambridge.
He had no University lectureship; in the year he lived on his King's College fellowship, as logician and number theorist. Unusually for a mathematician, he joined in Wittgenstein's classes on the philosophy of mathematics; unusually again, he engineered gear-wheel parts for a special machine to calculate the Riemann Zeta-function.
Publicly, he sponsored the entry into Britain of a young German Jewish refugee. Secretly, he worked part-time for the British cryptanalytic department, the so-called Government Code and Cypher School.
His appointment marked the first scientific input into a hitherto arts-based department. That revolution was caused by the failure of pre-scientific methods to penetrate the mechanical Enigma cipher used by Germany.
No significant progress was made, however, until the gift of vital ideas and information in July from Poland, where mathematicians had been employed on the problem much earlier.
