Hula hooping might appear to be a simple physical activity. But there’s some complex math and physics at play as the hoop goes around your body, and scientists haven’t had a clear understanding of those hidden forces—until now. A team of mathematicians at New York University recently published research into the science of hula hooping in the Proceedings of the National Academy of Sciences.
Flora Lichtman is joined by Olivia Pomerenk, a PhD candidate in mathematics at New York University, and a coauthor of that paper. She talks with Flora about why the motion of hula hooping prevents the hoop from falling down and which body types make for the best hooper.
