the binary numbers
https://en.wikipedia.org/wiki/History_of_computer_science In 1702, Gottfried Wilhelm Leibnitz developed logic in a formal, mathematical sense with his writings on the binary numeral system. In his system, the ones and zeros also represent true and false values or on and off states. -
analaticall
Babbage had devised a plan to develop a machine that could use punched cards to perform arithmetical operations. The machine would store numbers in memory units, and there would be a form of sequential control. This means that one operation would be carried out before another in such a way that the machine would produce an answer and not faihttps://en.wikipedia.org/wiki/History_of_computer_science -
church-turing tesis
After the 1920s, the expression computing machine referred to any machine that performed the work of a human computer, especially those in accordance with effective methods of the Church-Turing thesis. The thesis states that a mathematical method is effective if it could be set out as a list of instructions able to be followed by a human clerk withhttps://en.wikipedia.org/wiki/History_of_computer_science -
incompleteness theorem

The mathematical foundations of modern computer science began to be laid by Kurt Gödel with his incompleteness theorem -
Alan Turing
https://en.wikipedia.org/wiki/History_of_computer_scienceIn 1936 Alan Turing and Alonzo Church independently, and also together, introduced the formalization of an algorithm, with limits on what can be computed, and a "purely mechanical" model for computing.[citation needed] This became the Church–Turing thesis, a hypothesis about the nature of mechanical calculation devices, such as electronic computers. The thesis claims that any calculation that is possible can be performed by an algorithm running on a computer, provided that sufficie -
z3
https://en.wikipedia.org/wiki/History_of_computer_scienceIn 1941, Konrad Zuse developed the world's first functional program-controlled computer, The principle of the modern computer was first described by mathematician and pioneering computer scientist Alan Turing, who set out the idea in his seminal 1936 paper -
Z4
