Time Bombe

The boys, Jamie and Jonathan and I went to Bletchley Park Museum today. All of us are fascinated by computing and the impact that Alan Turing had not just on the outcome of WWII but also the world today. 

Alan Turing, a national hero who had gravest of disservice laid against him that can never be repaired in any way.

The museum is absolutely fascinating and well worth a days visit. We spent 4 hours there and saw probably little of 50% of what was there, and, that excludes the computing museum next door.

And, this is where the day took a very odd turn. The whole process of decoding enigma was based on a number of attack techniques targeted against the coded german messages. One part of that was based entirely on the frequency of letters within open text. Pure probability analysis.

This subject of probability played directly back at Jamie today. 
What do you think would be the probability of meeting up entirely at random with someone who you shared a house within in your final year at Uni? 
Someone you haven't seen or had contact with since you graduated. Someone who lives over 120 miles away from you. 
Someone you next see sitting at the next table in the cafe at Bletchley Park? 
That is just what happened.
Maybe he should buy a lottery ticket!
