|The reycling symbol looks like three bent arrows chasing each other around a triangular loop. You often find it printed on cardboard cartons, envelopes, greeting cards, packages, and trash containers. It's also an intriguing mathematical object. Imagine joining the tip of one of the arrows to the tail of the next all the way around to create a continuous band. What's unusual about the resulting shape? It's a Möbius strip. [Produced 10 times a year by the publishers of Cricket magazine (in association with Smithsonian magazine), Muse features articles and activities for children 8 years old and up.]|
