Mathematics is the study of quantity, space, structure, and change. Mathematicians seek out patterns and formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity...

Biography

After joining the school, Couffignal hesitated to write a thesis on Symbolic Logic but after his meetings with Maurice d'Ocagne, he decided to focus on machines and on Mechanical Logic.

He published a variety of notes at the Academy of Sciences, with a focus on using binary computation by machines to solve new problems. Following Leibniz, he promoted binary numbers as the basis of calculating machines. Couffignal received his Doctorate of Sciences in 1938 with his thesis on Mechanical Analysis, demonstrating applications for machines to calculate celestial mechanics. Couffignal took on an interest in Cybernetics, influenced by his meetings with Louis Lapicque
Louis Lapicque
Louis Lapicque was a French neuroscientist who was very influential in the early 20th century. One of his main contributions was to propose the integrate and fire model of the neuron in a seminal article published in 1907...

With Lapicque, Couffignal compared the functioning of the nervous system
Nervous system
The nervous system is an organ system containing a network of specialized cells called neurons that coordinate the actions of an animal and transmit signals between different parts of its body. In most animals the nervous system consists of two parts, central and peripheral. The central nervous...

 and that of machines, as Wiener prepared his book Cybernetics, the book that established the foundations for the subject.

Between 1938 and 1960, Couffignal was the director of the Blaise Pascal Calculation Center. In 1945, he was named Inspector General of Public Teaching. In 1951, Couffignal prepared an international conference on thinking machines to bring together the greatest specialists in this new science, including Norbert Wiener
