Aerodynamic experts suggest that Adidas' Telstar 18 should fly true and be less controversial than balls from past tournaments. "This year's ball is not going to be spectacularly different from the one before," said John Eric Goff, a physicist at the University of Lynchburg in Virginia. Using wind-tunnel experiments, Goff, along with Sungchan Hong and Takeshi Asai at the University of Tsukuba in Japan, found that the ball's aerodynamic properties are similar to that of the Brazuca. They recently reported their  results  in the Journal of Sports Engineering and Technology. READ FULL ARTICLE.
