In the UK graduate modelling camp 2016 at Oxford our team had to model the swerve of soccer balls. The inspiration came from the fact that during the 2010 FIFA World Cup players complained about the "strange" trajectories of the new Adidas Jabulani ball. Robinho stated: "for sure the guy who designed this ball never played football".
We did 2D and 3D PDE models of the ball trajectories, and solved them analytically and numerically. Using the models we provided explanations for the observed phenomena.
We won the prize for best team performance among 5 teams!!
