Ever wondered what four dimensions really mean? Discover why knots can’t exist in 4D space — and how mathematicians use cubes and clever analogies to understand higher dimensions.

Platonic solids are regular bodies in three dimensions, such as the cube and icosahedron, and have been known for millennia. They feature prominently in the natural world wherever geometry 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 ...

Tony Robbin had started out as a painter. He created complex works filled with interwoven patterns and ambiguous figures to give the illusion of seeing more than one object in the same place at the ...

MR. MAIR states clearly in his preface the scope of his book, which deals essentially with the elementary geometry of a four-dimensional continuum of space and time, the existence of straight lines ...

Monkeys! Mathematical groups! 4-dimensional geometry! Together at last! This sculpture, called More Fun than a Hypercube of Monkeys, answers an open question: has the quaternion group ever appeared as ...

Alicia Boole Stott, the third daughter of mathematician George Boole, is probably best known for establishing the term "polytope" for a convex solid in four dimensions. Alicia was also a long time ...
