Close-up view of a surface representing hyperbolic space and its boundary at infinity. The existence of such a surface was predicted by the mathematician John Nash in the 1950s. It has now actually been constructed, with the help of computers, by a team of scientists, who are attempting to visualise paradoxical mathematical objects. This surface, resulting from an infinite entanglement of corrugations (or folds), has an astonishing property: the shortest path between a point on its sinuous edge and any other point on this surface is infinitely long. Visualisations of this kind make it possible to explore a new geometry, half-way between that of fractals and that of ordinary surfaces: the geometry of smooth fractals. This image is one of the winners of the 2022 La preuve par l’image (LPPI) photography competition.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
