Mobius+Strip+by+Harry

A mobius strip has only one side. It sounds impossible, but it does. To understand it, you have to make one. Make a mobius strip by twisting a strip of paper 180 degrees and tape the ends together. Color each side a different color before taping. The fact that it only has one side will be more obvious. Try tracing a finger all the way around the strip. The Mobius Strip is named after August Ferdinand Mobius, an astronomer and mathematician. Mobius was born in 1790. He discovered the mobius strip in September of 1858. He wrote an article on it in 1865. Though Mobius got the credit, the first person to both discover the strange three dimensional figure and publish his finding was Johan Benedict Listing. He found it in July 1858 and published his findings in 1861. Even so, knowledge of the strip may date back to ancient times where mention of something similar is made in an Alexandrian manuscript.
