I've been writing a book, on and off, for several years now. The book is intended to be a popular science book about the history of computers. I'm a computer scientist by profession and so I've long had an interest in this subject.
The idea of this blog is to encourage me to keep working on the book by being able to share both the process of writing it and elements from it with who ever decides to follow the blog of just drop by.
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".
