*Möbius band*(/ˈmɜːrbiəs/ (non-rhotic), US: /ˈmeɪ-, ˈmoʊ-/; German: [ˈmøːbi̯ʊs]), also spelled

*Mobius*or

*Moebius*, is a surface with only one side (when embedded in three-dimensional Euclidean space) and only one boundary. The Möbius strip has the mathematical property of being unorientable. It can be realized as a ruled surface. It was discovered independently by the German mathematicians August Ferdinand Möbius and Johann Benedict Listing in 1858.
