Mechanisms and Mathematics

A mechanism is commonly perceived as a device for combining movement. Thus, physics, modeling, mathematics, movement and therefore technologies and mechanisms are intimately linked. They manifest themselves in a thousand clever and elegant ways, through gears, Archimedes' screw, clocks, engines, looms, punched cards and all the machines that human ingenuity has been able to design. Today, electronics has transformed the landscape by integrating other subtle movements: that of electrons and the transmission of information.

30 years of Tangente

Who would have bet, in 1987, when a few enthusiasts had the outlandish idea to create a professional magazine devoted to the place of mathematics in the world around us, that Tangente, the title they had given it, would still exist 30 years later and would become the universal reference in mathematical culture? To celebrate this anniversary, the Musée des arts et métiers, open free of charge on Sunday, December 3, allowed thousands of enthusiasts to attend numerous events: visits, animations, workshops, book signings, artistic exhibitions, conferences, shows, and the award ceremony for the Affaire de Logique competition.

Gaston Darboux: geometer and artist
