Where Do I Stand?!

Many optical illusions have mathematics at their foundation. Speaking of a foundation, where is the one in this image? Some optical illusions have their roots in the "impossible shapes" created by mathematicians Roger and L. S. Penrose, as can be seen in the work of M. C. Escher who frequently used these shapes as a basis for his art. Click here to find an optical illusions slide show.

Impossible Triangle & MCE




This object is known the Penrose Triangle or Penrose Tribar, after Sir Roger Penrose, the mathematical physicist (and recreational mathematician who created it. Dutch artist M. C. Escher was interested in mathematics and used this impossible mathematical shape twice over to create his lithograph "Waterfall" in 1961. Can you see where and how it is used? After figuring that out, you might want to check out the wild video on YouTube posted below Escher's work.
