Dải Möbius (The Möbius strip)

The Möbius strip, named after mathematician August Möbius, is a topological surface with very interesting properties. It is a one-sided, non-standard strip that connects at its ends, forming a loop. It is characterized by having only one edge and one surface, meaning that you can travel along it and return to the starting point, passing through both sides of the strip without interruption. The Möbius strip is an example of a fascinating mathematical concept and is often used in art, science, and various fields as a symbol of infinity or unity.
