THE IMPOSSIBLE REALITY 

By Andreea Nicoleta Radu

Mauris Cornelis Escher (17 June 1898 – 27 March 1972) was a Dutch graphic artist who created impossible constructions and lithographs and mezzotints about the exploration of the infinity, architecture and tessellations.

One of his most populary works was the lithograph Convex and Concave. In this work, many of the structure's features can be seen as both convex shapes and concave impressions.

The windows, roads, stairs and other shapes can be perceived as opening out in seemingly impossible ways and positions. Even the image on the flag is of reversible cubes. One can view these features as concave by viewing the image upside-down.

This is a very good example of   Escher's mastery in creating illusion of "Impossible Architectures".





Beldevere is another of his famous impossible structures. In this work front and back is an impossibility and so cannot be illustrated. On the floor of the lower platform, that is to say indoors, stands a ladder which two people are busy climbing. But as soon as they arrive at a floor higher, they are back in the open air and have to re-enter the building.

It is useful to provide different perspectives of the same software architecture. Thereby, it is important that still the same 'reality' is represented.

THE IMPOSSIBLE CUBE

An impossible cube is a cube in which the edges are depicted as solid beams and all the corners appear to be correct. But the edges of the cube overlap in ways that aren't physically possible.

The illusion plays on the human eye's interpretation of two-dimensional pictures as three-dimensional objects. Visual perspective is used to create the illusion of depth, but the three edges on the bag of the cube are placed in the foreground.
