Möbius Strip (Triple Twist)
A topological wonder with one side and one edge
Summary
A Möbius strip is a mathematical surface with only one side and only one edge. You can make one by giving a strip of paper a half twist and joining its ends. This model has three twists, an extended version of the classic single-twist Möbius strip.
In depth
Discovered independently in 1858 by August Ferdinand Möbius and Johann Benedict Listing, the Möbius strip is one of the most counter-intuitive examples in topology. The classic (single-twist) Möbius strip is a non-orientable surface: if you slide your finger along it and come back to the start, you find yourself on the "other side". The triple-twist version in this model still has a single side (the rule for an odd number of twists). If you cut the classic (one-twist) strip along its centre line, you do not get two separate loops but one longer loop; this unexpected result is the signature of Möbius topology. Practical uses: conveyor belts (both "sides" wear evenly), electronic resistors and certain models in quantum mechanics.
