enigma

we went to a lecture at the wolsey theatre in ipswich last night about the enigma machine and bletchley park in the second world war. it was quite long (almost three hours) but the fact that the lecturer talked without notes for the entire period was singularly impressive.

at the end of the session, the floor was opened up and two people identified themselves as having worked at bletchley during the war. all in all an interesting evening.
