Read about the life and works of Alan Turing [1]. Not only did he do seminal work for invention of general purpose computer, he actually went on to study the limitations of this theoretical computer even before it became a practical reality. Every time you see a captcha, recall that CAPTCHA = Completely Automated Public Turing test to tell Computers and Humans Apart.

Cool. I have read some stuff about him and he has interested me; I will look into more literature on him. Thanks.
