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 ...

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 ...

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, ...

Regardless of your existing knowledge of science, a fourth dimension of space is a very difficult concept to grasp. This isn’t the fourth dimension of time we’re talking about, but another spacing ...

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 ...

Yes, it is possible to create a three-dimensional image of a four-dimensional object: a hypercube is the four-dimensional analogue of a cube, and it has a well-known three-dimensional image that looks ...
