New research shows the way soccer players move about the field bears similarities to the manner in which particles behave under the chaotic conditions of turbulence. This discovery is one of the many made in an effort to better understand turbulence, which is a surprisingly active and pressing field. More than half a millennium after Leonardo Da Vinci first coined the term, in 1507, physicists still don’t have a complete understanding of what goes on under conditions of turbulence, and no equation exists to accurately describe the phenomenon.
