M.C. Escher

In his graphic art, he portrayed mathematical relationship among shape figures and space. Additionally, he explored interlocking figures using black and white to enhance different dimensions.

 He is known for his mathematically inspired woodcuts lithographs and mezzo tint. These feature impossible constructions, explorations of infinity, architecture and tessellation

 His understanding of mathematics were largely visual and intuitive. Escher's work had a strong mathematical component and more than a few of the worlds which he drew are built around impossible objects such as the Necker cube and the Penrose triangle.

Relativity

• Each inhabitant live in one of the gravity well, where normal physical laws apply
• There are three sources of gravity, each being orthogonal to the two others
• The confusion comes from the fact all three gravity sources are depicted in the space
• The structure has six stairways and each stairway can be used by people who belong to two different gravity sources.
• This means two people use the same stairway in the same stairway in the same stairway in the same direction and on the same side, but each using a different face of each step, which means one descends the stairway as the other climbs it

 Interrogation about perspective and the representation of three-dimensional images in a two dimensional picture are at the core of Escher's work
