Binary numbers and the village of Campagna

The binary number system is the mathematical 'language' that underlies computers. The binary number system has many fathers. The first to propose its use was Juan Caramuel with the publication of the volume "Mathesis biceps. Vetus, et noua" published in Campagna in 1669. There is also a trace of it in the works of Nepero. Later, the German mathematician Gottfried Wilhelm von Leibniz was the first to study its arithmetic. That is why this system of numbering is considered among his greatest inventions. However, it did not have an immediate following. Binary arithmetic was soon forgotten and rediscovered only in 1847 thanks to the English mathematician George Boole who opened the horizon to the great schools of mathematical logic of the twentieth century and especially to the birth of the electronic calculator.
