Alan Turing’s Path to Success

Alan Turing, born in 1912 to wealthy parents, attended Hazelhurst and Sherborne School before earning a scholarship to King’s College, Cambridge. He focused on mathematics, and his research was published in prestigious Proceedings of the London Mathematical Society.

Turing: The Father of Modern Computing

Alan Turing’s pioneering work on “On Computable Numbers” and the creation of a universal Turing machine revolutionized modern computing, laying the foundation for what we know today as computers.

Alan Turing, one of the most influential pioneers in computer science, published the paper “On Computable Numbers, with an Application to the Entscheidungsproblem” in 1936. Considered the bedrock of the modern computer science, his pioneering work on this foundational mathematics issue inspired the creation of a universal Turing machine that could carry out multiple mathematical procedures, making it the precursor to modern computers.

Turing received his PhD at Princeton University where he speculated on “oracle machines,” mathematical models of computers that could communicate with an external database, such as the World Wide Web. Despite being a theoretical genius, he was also immensely practical and became interested in creating a perfectly general computing machine.

The universal Turing machine he conceived of was a revolutionary invention, equipped with an “endless paper tape” possessing infinite memory and a “read/write” scanner capable of reading the information on the tape that included the machine’s program and computational data. However, it wasn’t until World War II that Turing and Max Newman figured out how to construct a working universal Turing machine.

Turing’s theory and invention of the universal Turing machine opened up new horizons in the computing world and demonstrated that machines could perform the same repetitive functions as human computers. He believed that computers could enter any field normally covered by human intellect and even compete on equal terms. In short, Turing was the father of modern computing as we know it today.

The Code-Breaker Hero

During World War II, Alan Turing had the crucial role of breaking German codes, including Enigma and Tunny. He designed and built the anti-Enigma “bombe,” which decoded an incredible rate of messages. Turing’s efforts shortened the European theater of the war by two to four years, saving 14 to 21 million lives. Alongside other heroes, he significantly contributed to the Allied victory against Nazi Germany.

The Evolution of Electronic Computers

Discover the evolution of electronic computers from Turing’s algorithms that cracked Tunny to the development of DEUCE, the first commercial electronic computer.

Alan Turing’s pursuit to crack the Tunny code led to the creation of algorithms that triggered the birth of Colossus, the first electronic computer. The brilliant mind of Tommy Flowers further developed Colossus, which eventually led to the birth of DEUCE. DEUCE proved to be one of the world’s first commercial electronic computers, and its creation can be traced back to Turing’s algorithms and his well-calculated designs of the Automatic Computing Engine (ACE). The journey of electronic computers began with a quest to uncover secrets, but it ended up changing the world’s technological landscape.

Alan Turing: A Pioneer in AI and ALife

Alan Turing was a multifaceted intellectual who made groundbreaking contributions to the field of artificial intelligence (AI) and artificial life (ALife). Turing programmed the “first universal Turing machine in hardware” while working at the Royal Society Computing Machine Laboratory in Manchester. He then turned his attention to AI and created computer chess-playing software which became the first-ever AI program. Turing’s research also delved into biology, exploring how organisms develop their structure and form. His “reaction-diffusion” theory discusses how chemicals inside an embryo set the pattern for its growth. In his paper, “Intelligent Machinery,” he discussed designing a synthetic nerve cell and constructing a machine using artificial nerve cells. Turing also noted that the brain might be a computer, in addition to being the first to establish a connection between AI and ALife. He received the prestigious Order of the British Empire award, which he kept in a box of nails and screws. Turing was a strange man who preferred counting pedal rotations instead of fixing a faulty roller chain on his bicycle. His legacy in AI and ALife is unparalleled and continues to be celebrated even today.
