Impossible
staircase - one of the basic impossible projects. It is sometimes called
the endless stairs . If someone would want to go up or go down on her,
then, after passing four flights of stairs, he would have been in the
same point where you started your journey. A walk on the stairs goes on,
and without moving from its starting point.
Model impossible
staircase developed by English biologist Lionel Penrose (Lionel Penrose)
with his son - a renowned mathematician Roger Penrose (Roger Penrose) .
She was the first impossible object that M. Escher (MC Escher) used in
his work - a lithograph "Ascending and Descending" ("Ascending and
Descending") , which depicts the mysterious monastery on its roof
recreated impossible staircase.
Although Asher and
Layoner and Roger Penrose made impossible staircase known around the
world, it was opened a few years before their Swedish artist Oscar
Reutersvard (Oscar Reutersvard) . But neither Penrose nor Escher were
not familiar with the works Reutersvard.
Consider in more
detail the impossible staircase (see Fig. Below). If you move the ladder
clockwise, we will continually rise, and if we move counter clockwise,
then - down. While it may seem that such a construction is not possible
in the real world, in fact (like many of impossible projects )
impossible stairs can be represented as a real model. The secret here
lies in the fact that the real model impossible stairs should be a gap
in the area of the right corner (shown), which in this case is not seen
as a viewpoint chosen deliberately to hide the gap.
