# The legacy of Bletchley Park on UK Mathematics

*by Daniel Shiu*

World War II, and Bletchley Park in particular, saw the introduction of academic mathematicians to the problems of cryptanalysis. The effect of mathematical thinking on cryptanalysis is well-studied, but in this talk we consider the opposite question: how did mathematiciansâ€™ experiences at Bletchley Park affect their subsequent mathematical work? We will consider three main themes: a shift in statistical thinking, the use of computers in mathematics, and the persistence of collaboration between individuals who met at BP.
