The Universal Machine is published!!!
It's been a long journey; back on April 5 2010 I started this blog with a post that said: "Computers you see are not like other tools that we've invented. Think of wheel and axle for example. This invention let man build carts and wagons and so more easily move heavy loads around. Thousands of years later, although we now have engines instead of horses the basic use of the invention hasn't changed. Now think of the computer. They were first used to crack military codes and design H-bombs, and then to do the payroll for large companies, but now we use them to communicate with friends, play (and compose) music, design buildings, create virtual worlds, make movies, this list is endless and constantly growing. You see the computer fundamentally does not crack codes or write blogs, a computer manipulates symbols and it can perform any task that can be represented by symbols. In this sense, in the words of Alan Turing, a computer is a "universal machine"."
Over two years later, timed to coincide with the centenary of Alan Turing's birth the Universal Machine tells the complete story of Turing's legacy. It can be purchased from Amazon but you can read a sample chapter on this blog from the "Free Chapter" tab above.
