things change

Alan Turing: The Enigma by Andrew Hodges is a thorough and, at 700 pages, a long book. It’s well written and easy to read but at the same time it’s also a difficult read. The mathematics, the computing, the ideas, make for a challenging book, and sometimes I cut corners and skimmed!
The book is an exploration and history of so many things – the times, early computing, WWII – as well as being the story of a complex human being. Highly recommended.
