A Möbius strip is a looped object with one continuous side and one edge. If you draw a line along the surface of a Möbius strip, it will travel along both faces of the surface before returning to the starting point.
It can be created by connecting the ends of a narrow strip of material with an odd number of half twists. If the long edges were able to connect, it would form a Klein Bottle.
The shape is named after German mathematician August Ferdinand Möbius who brought attention to its mathematical significance in 1858, but it had been known throughout antiquity, as Möbius strips appear in Mesopotamian and Roman artworks. In fact, the Möbius strip was instrumental to the formation of the field of topology, the study of geometric properties that remain unchanged as an object is deformed, which is vital for physics.
