A Möbius strip is a surface with only one side and one edge. It can be created by taking a rectangular strip of paper, giving it a half-twist, and then joining the ends together. This unique shape challenges our understanding of dimensions and surfaces in geometry. Möbius strips are often used in mathematics and art to illustrate concepts of infinity and non-orientability. They can also be found in various applications, such as conveyor belts and in the design of certain types of jewelry, showcasing their intriguing properties in both theoretical and practical contexts.
