Kinetic art and geometry: Vasarely, Le Parc, Morellet

The last time Argentine sculptor and painter Julio Le Parc exhibited in New York was in 1973. The artist has just brought a successful exhibition in Paris to a close at the Perrotin gallery in the 3rd arrondissement. In the meantime, kinetic art had faded from view.

The cube’s geometric tricks: cross-sections and symmetries

The cube is such a familiar object that few people know its formal name: the regular hexahedron. Yet that familiarity is deceptive... To see why, let’s slice a cube into sections: this old familiar shape still has a few surprises in store!

Trompe-l'oeil geometry: razzle dazzle camouflage

Hard though it may be to believe, geometry has sometimes helped to fight the enemy in wartime—or at least to limit the severity of its attacks.

The first America: Mathematical cartography in 1507

This little "green globe," dating from the early 16th century and measuring just fourteen centimeters in diameter, is the first to bear the name "America"—in four places, no less, as if to proclaim the discovery beyond doubt.

The fascination of gears: geometry and mechanics

Gears are both objects of fascination and symbols of mechanics. Determining the shape of their teeth is a sophisticated mathematical problem. Yet this long history, which stretches back to antiquity and is still being written, remains remarkably little known!

The Earth in a ping-pong ball: Nash–Kuiper

Nothing is mathematically impossible! Although, back in the 1950s, the Dutch mathematician Nicolaas Kuiper and the American John Nash had already proved the existence of a vast class of paradoxical mathematical objects (flat tori in 3D, shrunken spheres…), they lacked the tools to visualize them

Fractals in film: from geometry to special effects

Fractal geometry was central to the earliest computer-generated imagery on the big screen. The study of self-similar forms found in nature gave rise to the first computer-generated images… and thus spawned an entire entertainment industry!

Georges Méliès: special effects, anamorphosis and maths

Georges Méliès is often described as the creator of cinematic spectacle, while the Lumière brothers are the inventors of the cinematograph. In fact, Méliès was passionate about technology. He found solutions to problems that can readily be expressed in mathematical terms.
