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 topology, making it a popular subject in mathematics. The Möbius strip has interesting properties, such as being non-orientable, meaning that if you travel along its surface, you can return to your starting point without crossing an edge. It has applications in various fields, including art, science, and engineering, often symbolizing infinity and continuity.
