> Which of the following is a three-dimensional object, but only has one side?And the answer: the Möbius strip. You can make a Möbius strip at home, using a rectangular strip of paper andtape. Take one end of the paper and make a half twist, and then tape the twoends together. You have now created a 3-D object that has one continuous side!Photo credit: David Benbennick[https://commons.wikimedia.org/wiki/User:Dbenbenn].In 1858, two scientists madea simultaneous discovery: the Möbius strip. August Ferdinand Möbius, amathematician and theoretical astronomer, discovered the phenomenon at the sametime as Johann Benedict Listing, a younger mathematician. The irony is perhapstoo great to ignore: the two scientists made the same discovery, at the sametime, coming from different directions...much like the Möbius strip itself. The Möbius strip is considered to be an impossible shape, meaning it has neverbeen observed in nature. It defines an un-orientable object – there is nodistinct up, down, left or right. Yet that has hardly stopped scientists andartists alike from replicating it into oblivion. Indeed, it has served as asource of inspiration for jewelry, the model for artworks, and more. Intechnology, it has even been incorporated to maximize the functionality of somemachines. Conveyor belts use Möbius strips because they allow the entire surfacearea of the belt to receive an equal amount of wear, which makes it last longer.Learn more about the Möbius strip here[https://www.britannica.com/science/Mobius-strip].
