GCHQ has released two research papers authored by Alan Turing, which are believed to have been written while he was at Bletchley Park, engaging in code cracking during World War II.
The papers have previously been regarded as still too sensitive to make public, but you'll now be able to view them at the National Archives at Kew, although you'll need to make arrangements and bring ID to do so.
The handwritten maths research papers are entitled "Paper on Statistics of Repetitions" and "The Applications of Probability to Crypt".
The first paper is an informal piece where Turing details a process to evaluate the best statistical means of determining whether two cipher messages use the same key. The second piece is a longer affair, and consists of a detailed probability analysis of code cracking problems. It all sounds like pretty heavy stuff.
The second paper has been dated at either 1941 or 1942, given that Turing mentions Hitler in it, declaring that the German dictator was 52-years-old.
A spokesperson for GCHQ commented: "We are delighted to release these papers showing more of Alan Turing's pioneering research during his time at Bletchley Park. It was this type of research that helped turn the tide of war and it is particularly pleasing that we are able to share these papers during this centenary year."
Alan Turing's centenary celebration will be happening in June, as he was born on the 23rd of the month in 1912. We expect a Google doodle will be along to mark the occasion.
