Do you remember the impossible figures from math class? The ones that seemed to defy the laws of physics and could not be represented in the real world? It turns out some of them can! Here are some of the impossible figures spotted in real life.
Penrose Triangle is named after British mathematician and physicist Roger Penrose; this impossible figure was first described in 1934. This slender triangle appears to be a two-dimensional shape, but in reality, it is three-dimensional due to its impossible angles. In the real world, it has been spotted on an ice sculpture located in Norway and on a sculpture in Seattle, Washington.
Impossible Cube is also called the “Impossible Tribar.” This math figure looks like an ordinary cube, but it is made up of only three bars. It has been spotted worldwide in places such as Belgium and South Korea, where people have crafted it from metal and wood.
Necker Cube is a math figure, a cube-like structure with straight edges that appear in two different directions simultaneously. In real life, it has been spotted everywhere, from math classrooms to artwork designs.
Penrose Steps is similar to the impossible triangle, and this math figure appears to be a set of steps that cannot possibly exist in the real world. However, it was spotted as part of a building design in the Netherlands and on several sculptures worldwide.
Angel and Devil Impossible Escher is Created by Dutch graphic artist M.C. Escher. This math figure looks like an angel and devil in the same image, but it is two separate impossible figures. In real life, this math figure was spotted on a mural in Amsterdam and as part of a street art display in Paris, France.
So next time someone tells you something is “impossible,” think again! These five math figures prove that impossible figures can exist in the real world.
