Scientific Reports this month includes a timely article on the aerodynamics of different types of soccer balls, “Effect of panel shape of soccer ball on its flight characteristics.” The study included a kick robot that uniformly kicked each of the balls. Thought all soccer balls were the same? think again, “Soccer balls are typically constructed from 32 pentagonal and hexagonal panels. Recently, however, newer balls named Cafusa, Teamgeist 2, and Jabulani were respectively produced from 32, 14, and 8 panels with shapes and designs dramatically different from those of conventional balls. The newest type of ball, named Brazuca, was produced from six panels and will be used in the 2014 FIFA World Cup in Brazil.”
