  • People in Computing
    • Charles Babbage
      • a problem solver, engineer and inventor who lived during the 18th century
        • He manufactured an Analytical Engine
        • He met Ada Lovelace when she was seventeen
        • Logical thought is the formal processes used in thinking and reasoning; it is what most of us use to answer questions as human nature
      • famous for designing the first ever computing machine which ran on steam
      • he worked out the steps needed to create the numbers on a dial, as well as using cogs to shift the numbers; concluding in a mathematical result that was accurate 
    • Ada   Lovelace
      • was alive during the 19th century and worked as a mathematician and writer
        • died at the young age of 36 due to Uterine cancer
        • she is considered by many as the “first computer programmer”.
        • at 17 years-old, she met Charles Babbage
      • she wrote the world's first machine algorithm for an early computing machine, of which existed only on paper
      • She is well known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine
    • George Boole
      • a mathematician who lived in the 19th century
      • thought of how humane thinking and logic could be translated into mathematical terms which could later lead to computing
      • The three logic gates are used to decrypt messages by use of 1 and 0
        • An AND gate takes two inputs to produce a single output. To get “1”, both inputs must also be 1
        • An OR gate is the same; however, a 1 MUST be present in order to output “1”. 
        • The NOT gate produces an output which is the opposite of the input.
    • Alan Turing
      • an English computer scientist and mathematician, who was alive during the 20th century
        • Turing invented a machine, which worked via the inter-wiring of rotors 
        • After later analysis, it was believed to be that his cause of death was through cyanide poisoning.
        • He suffered cruel treatment from the mostly homophobic British authorities
      • He played a crucial role in deciphering the German “Enigma” codes which were very confusing 
      • Thanks to his machine and invention (the Bombe) the British could pin-point the way the Enigma was set up, simply by feeding the message into the machine
