If it weren't for Alan Turing, the modern computer would not exist. He invented a code breaking machine during WWII known as the Bombe, which is considered by most to be the first general purpose computer. His paper titled "On Computable Numbers, with an application to the Entscheidungs problem" serves as the foundation for modern computing sciences. While he didn't invent the computer you're reading this list on, without him we wouldn't have modern computers.
Alan Turing was born on June 23, 1912, in London. In his seminal 1936 paper, he proved that there cannot exist any universal algorithmic method of determining truth in mathematics, and that mathematics will always contain undecidable propositions. That paper also introduced the "Turing machine. His papers on the subject are widely acknowledged as the foundation of research in artificial intelligence.
This picture of rules for a Turing machine needs to be on a page in the book Khatchig is reading. The picture needs to be printed on something that looks like the same paper stock of the "How to build a Turing Machine" book.
The ideas surrounding machines "taking over" has long been a popular topic both for writers and scientists. In 1950 the father of modern computing Alan Turing, wrote a paper which opens with the words: "I propose to consider the question: Can machines think?"
