“Turbulence remains one of the greatest unsolved problems in classical mechanics,” says James Beattie, a postdoctoral researcher at the Canadian Institute for Theoretical Astrophysics (CITA) in the Faculty of Arts & Science at the University of Toronto, who also holds a joint appointment at Princeton University.

“This despite the fact that turbulence is ubiquitous: from swirling milk in our coffee to chaotic flows in the oceans, solar wind, interstellar medium, even the plasma between galaxies.

“The key distinction in astro...
