We are said that the real world in which humans live is present in three dimensions or four dimensions. "Three-dimensional" is a relatively easy-to-understand concept for people who live while ...

Previous investigations of the neural code for complex object shape have focused on two-dimensional pattern representation. This may be the primary mode for object vision given its simplicity and ...

Last spring, mathematician Henry Segerman found a peculiar post on Facebook. It was by a programmer who had could not conjure mental images---a condition called aphantasia. Segerman immediately ...

4D, most known in science fiction and theoretical physics, is being actualized by the 4D printing technology developed at MIT’s Self-Assembly Lab. This breakthrough enhances conventional 3D printing ...

Marc ten Bosch’s side project 4D Toys is a unique physics-based toy box using the game engine he created for Miegakure, a groundbreaking 4D puzzle-platformer. Launched on June 2nd for SteamVR and iOS, ...

Using components made from smart shape-memory materials with slightly different responses to heat, researchers have demonstrated a four-dimensional printing technology that allowed creation of complex ...

When you are sent to do a bit of work experience in the office of a university science department you don’t normally expect much more than a bit of boring filing and some tedious photocopying. So ...

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 ...
