In a Facebook post, the Enigma Museum in Poznań revealed: “The Enigma was deliberately THROWN into the sea on May 4th or 5th when U-boats were ordered by Karl Donitz to end the war and surrender to the English. It is clear that the crews did not want a top-secret code device to fall into the hands of the enemy, even when the war was already lost.”

However, this version is doubted by Dr Jann Witt, a historian from the German Naval Association. He told Deutsche Presse-Agentur that he believed the machine was thrown overboard from a German warship in the final days of the war.

He claimed that it is less likely to have come from a scuttled submarine as U-boats used the more complex four-rotor Enigma machines. This version, he says, only has three rotors.

Britain’s £50 Note Will Honor Computing Pioneer Alan Turing - The New York Times

LONDON — Alan Turing, the computing pioneer who became one of the most influential code breakers of World War II, has been chosen by the Bank of England to be the new face of its 50-pound note.

The decision to put Mr. Turing on the highest-denomination English bank note, worth about $62, adds to growing public recognition of his achievements. His reputation during his lifetime was overshadowed by a conviction under Britain’s Victorian laws against homosexuality, and his war work remained a secret until decades later.

“Alan Turing was an outstanding mathematician whose work has had an enormous impact on how we live today,” Mark Carney, the governor of the Bank of England, said in a statement. “As the father of computer science and artificial intelligence, as well as a war hero, Alan Turing’s contributions were far-ranging and path breaking.”

“Turing is a giant on whose shoulders so many now stand,” Mr. Carney added.

The central bank announced last year that it wanted to honor someone in the field of science on the next version of the bill, which was last redesigned in 2011, and Mr. Turing was chosen from a list of 227,299 nominees that included Charles Babbage, Stephen Hawking, Ada Lovelace and Margaret Thatcher (who worked as a chemical researcher before entering politics).

“The strength of the shortlist is testament to the U.K.’s incredible scientific contribution,” Sarah John, the Bank of England’s chief cashier, said in a statement.

The bank plans to put the new note into circulation by the end of 2021.

Bank of England bills feature Queen Elizabeth’s face on one side, and a notable figure from British history on the other. Scientists previously honored in this way include Newton, Darwin and the electrical pioneer Michael Faraday. The current £50 features James Watt, a key figure in the development of the steam engine, and Matthew Boulton, the industrialist who backed him.

Mr. Turing’s work provided the theoretical basis for modern computers, and for ideas of artificial intelligence. His work on code-breaking machines during World War II also drove forward the development of computing, and is regarded as having significantly affected the course of the war.

Mr. Turing died in 1954, two years after being convicted under Victorian laws against homosexuality and forced to endure chemical castration. The British government apologized for his treatment in 2009, and Queen Elizabeth granted him a royal pardon in 2013.

The note will feature a photograph of Mr. Turing from 1951 that is now on display at the National Portrait Gallery. His work will also be celebrated on the reverse side, which will include a table and mathematical formulas from a paper by Mr. Turing from 1936 that is recognized as foundational for computer science.

D’Alan Mathison Turing (23/6/1912- 7/6/1954), le grand public n’a longtemps rien su. En quelques années, Turing est devenu la figure rêvée du génie scientifique maltraité par les conventions morales d’une époque.

Collection of letters by codebreaker #Alan_Turing found in filing cabinet
▻https://www.theguardian.com/science/2017/aug/27/collection-letters-codebreaker-alan-turing-found-filing-cabinet

A lost collection of nearly 150 letters from the codebreaker Alan Turing has been uncovered in an old filing cabinet at the University of Manchester.

The correspondence, which has not seen the light of day for at least 30 years, contains very little about Turing’s tortured personal life. It does, however, give an intriguing insight into his views on America.

In response to an invitation to speak at a conference in the US in April 1953, Turing replied that he would rather not attend: “I would not like the journey, and I detest America.”

Letters reveal Alan Turing’s battle with his sexuality
▻http://www.theguardian.com/science/2015/aug/23/alan-turing-letters-reveal-battle-sexuality

He writes: “Mother has been staying here, and we seem to be getting on a good deal better. I have been subjecting her to a good deal of sexual enlightenment and she seems to have stood up to it very well. There was a rather absurd dream I had the other night in which I asked mother’s opinion about going to bed with some men and she said: ‘Oh very well, but don’t go walking about the place naked like you did before.’”

Keira Knightley: Where are the Female Geniuses in Film?
▻http://www.breitbart.com/big-hollywood/2015/01/15/keira-knightley-where-are-the-hollywood-films-about-female-geniuses

Actress Keira Knightley, who was just nominated for an Oscar for her supporting role in The Imitation Game, wants to know when Hollywood films will start to feature female geniuses.

The 29-year-old starlet (NDLR: glups!) (...)

“You’re asking if I’ve ever been offered a biopic about a female genius?” She asked. “No! What is up with that! Go on, you’re a writer, write one. I would love to play a genius.”

The Imitation Game, which stars Benedict Cumberbatch, is about British mathematician, cryptanalyst, logician, and computer scientist, Alan Turing.

(...) Knightley further pressed the writer on who he would choose to write a film about. “What about the mathematician who’s just won the — God, what’s the biggest maths prize? Fields Medal. What’s her name?” she asked. “That’s even worse. I can’t remember her name.”

(Iranian mathematician Maryam Mirzakhani was the woman Knightley was referring to.)

Alan Turing : 1912-2012
►http://eljjdx.canalblog.com/archives/2012/05/20/24288318.html

Le 17 mai dernier a eu lieu la 8ème journée mondiale contre l’homophobie, l’occasion d’évoquer le destin tragique de Alan Turing, dont on fête le centenaire en cette année 2012.

En 1928, Hilbert propose ce qu’il appelle dans sa langue le Entscheidungsproblem (problème de la décision) : peut-on toujours prouver mécaniquement (par un algorithme) qu’un énoncé est (ou non) un théorème. Ce problème est lié au problème de l’arrêt : si j’écris un algorithme dans un langage de mon choix, peut-on vérifier sans le lancer que l’algorithme ne va pas boucler indéfiniment (et donc, qu’il va finir par s’arrêter) ?
