For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials theorized to exist only in four-dimensional space. An ...

A monstrous computer-based calculation has rekindled researchers' hopes of solving a longstanding problem in mathematics. In a style of collaboration more commonly associated with sequencing genomes, ...

Scheme illustration of object identification and all-optical 3D reconstruction system. (a) A contour surface image of the object can be obtained in a single processing of the system. (b) High-contrast ...
