15) " I can see beyond the mundane.."


The figure shown above is rebuilt version of an X.
Wiki says that "The X searched for possibly correct settings used for an Enigma message (i.e., rotor order, rotor settings, etc.), and used a suitable crib: a fragment of probable plaintext. For each possible setting of the rotors (which had of the order of 1019 states, or 1022 for the four-rotor U-boat variant), the X performed a chain of logical deductions based on the crib, implemented electrically. The X detected when a contradiction had occurred, and ruled out that setting, moving onto the next. Most of the possible settings would cause contradictions and be discarded, leaving only a few to be investigated in detail. Y 's X was first installed on 18 March 1940. More than two hundred X s were in operation by the end of the war.

And now about Y....


In August 2009, John Graham Cumming started a petition urging the British Government to posthumously apologise to Y  for prosecuting him as a homosexual. The petition received thousands of signatures.Prime Minister Gordon Brown acknowledged the petition, releasing a statement on 10 September 2009 apologising and describing Y 's treatment as "appalling":
Thousands of people have come together to demand justice for Y and recognition of the appalling way he was treated. While Y was dealt with under the law of the time and we can't put the clock back, his treatment was of course utterly unfair and I am pleased to have the chance to say how deeply sorry I and we all are for what happened to him ... So on behalf of the British government, and all those who live freely thanks to Y's work I am very proud to say: we're sorry, you deserved so much better.
Now,Id X and Y .

  1. wiki was an easy giveaway.. Y is Alan Turing and X refers to 'bombe', an electromechanical machine which could help attack Enigma-traffic faster during d war years(world wars)

  2. X-Bombe...Y-Alan Turing

  3. Both of you are right ofcourse...X is a bombe (derived from a polish bomba) and Y is the great Alan Turing.
