The Penrose stairs is an impossible object created by Lionel Penrose and his son Roger Penrose. It can be seen as a variation on the Penrose triangle. It is a two-dimensional depiction of a staircase in which the stairs make four 90-degree turns as they ascend or descend yet form a continuous loop, so that a person could climb them forever and never get any higher. This is clearly impossible in three dimensions; the two-dimensional figure achieves this paradox by distorting perspective.

The best known example of Penrose stairs appears in the lithograph Ascending and Descending by M. C. Escher, where it is incorporated into a monastery where several monks ascend and descend the endless staircase.

The staircase had also been discovered previously by the Swedish artist Oscar Reutersvärd, but neither Penrose nor Escher were aware of his designs.

“Cette situation est par ailleurs un nouvel exemple d’une tendance qui se matérialise de plus en plus ces dernières années: une inversion des flux de l’innovation. Avant, c’était le militaire qui innovait en premier grâce à ses abondants crédits, le monde industriel reprenait ses produits ensuite pour ses propres usages avant de les mettre dans le monde des consommateurs. Maintenant, il semble que cette tendance s’inverse de plus en plus souvent: regardez donc le nombre de technologies et services utilisés par les entreprise ayant émergées dans le monde des consommateurs!” Media & Tech | Google Android: utilisations militaires
