The document discusses the history and development of basketball, including the materials used in its equipment. It describes how James Naismith invented basketball in 1891 using a soccer ball and peach basket. Over time, the ball and hoop designs evolved into the modern basketball. Polymers are now used to make high-performance basketballs and shoes that improve grip, cushioning, and breathability to help players perform better. Specifically, today's basketballs have a bladder and synthetic leather cover made of polyurethane-impregnated fibers to keep the ball lightweight yet durable.
