MOBIUS STRIP
Mobius strip ( Amazing Geometry ) Mobius strip is a one sided surface that can be constructed by affixing the ends of a rectangular strip after having gived one of the ends a one half twist. The space exhibits interesting properties, such as having only one side and remaining in one piece when split down the middle. The properties of the strip were discovered independently and almost simultaneously by two German mathematicians, August Ferdinand Mobius and Johann Benedict Listing , in 1858. If you cut a mobius strip through the centre line, you will have one long strip with two full twist , rather than two seperate strips.
