The Möbius band, also known as the Möbius ring or Möbius strip, is a topological structure with only one face (surface) and one boundary. It was independently discovered by German mathematicians and astronomers August Ferdinand Möbius and Johan Benedict Listing in 1858. This structure can be easily made by rotating a paper tape half a circle and then sticking both ends together. In fact, there are two different types of Möbius belt mirrors that are symmetrical to each other. If the paper tape is rotated clockwise and then
