A Möbius strip is a surface with only one side and one edge, created by taking a rectangular strip of paper, giving it a half-twist, and then joining the ends together. This unique shape defies traditional geometry, as it challenges the concept of two-sided surfaces. The Möbius strip is often used in mathematics and art to illustrate concepts of infinity and non-orientability. It has applications in various fields, including topology, where it serves as a simple example of a non-orientable surface, and in engineering, where it can be found in conveyor belts and other continuous loops.
