I remove all times two stars because several points annoy me:
- There is very heavy passages, especially on mathematical philosophy, which can get less frequent, not necessarily savvy subtleties of basic research in mathematics ... Even if it illuminates on the general spirit prevailing (!) at that time, this little discourage many readers ...
- Along the passages speaking techniques are heterogeneous ... Some items are scanned quickly as if it were obvious (although not for non-mathematicians) and others persist in an extension child, which can be frustrating ...
- There is little cuttings into chapters / subchapters. There (memory) five large chapters, without any 'pause' .... Each chapter is very dense ... which sometimes gives the impression of spending one topic to another within a single page ...
- Some passages are really poorly written and / or poorly translated, and create a sense of confusion ... There are often errors (one thing and its opposite are told two pages apart)
- Even if the summary seems perfectly follow a time line, the story is not strictly chronological: for example there is talk of an anecdote in 1941, describes everything that happens in 1942, then returned to a point having been place in 1940 to talk again about the story of 1941, etc ... If it had held from time to time, this could boost the story, but it does happen and often adds to the sense of confusion ....
All this remains to detail: it is a very good book, exciting, which perfectly describes the visionary genius that was Alan Turing and the atmosphere in a world at war. The whole rest of my point of view a little heavy reading, contrary to the film, which tells the same story in a way (too) simple ...
