This is a new area of the Alan Turing website. I intend to place about 16 extracts from my book on these pages, to illustrate the range of material and style of my writing, and of course also to help explain what he achieved.
At present there are just three extracts:
This passage describes how in 1928 Alan Turing met and befriended another boy in his school, Christopher Morcom. This development ended his social isolation, and inspired his future progress. But it was also traumatic: this was not only first love, but led to a sudden and cruel bereavement.
This passage describes the moral and poltiical ambience at King's College, Cambridge University, where Alan Turing became a mathematics undergraduate in 1931, his response to this extraordinary environment, and his emotional development in 1933.
These pages concern Alan Turing's world-leading computer design of 1946. This passage explains the most important aspect of Turing's original plan for the Automatic Computing Engine: not the details of the hardware, but the principles as set forth by Turing which underlay the development and scope of software for the rest of the century.
