KLEIN BOTTLE– The Klein Bottle is named after Felix Klein (1848–1925). A translator misinterpreted the expression, turning Kleinsche Fläche (Klein’s surface) into Klein bottle. The English version prevailed and was translated verbatim back into German. The Klein bottle is a geometrical object consisting of a single surface inside and out, which is called a non-orientable surface. A 3D variant of the Möbius strip, it can only exist in four- dimensional space.
