What happened

New methods can help study the phenomenon of turbulence Gaby Clark Scientific Editor Robert Egan Associate Editor In his doctoral thesis, Michael Roop develops numerical methods that allow finding physically reliable approximate solutions to nonlinear…

Why it matters

Many processes in nature can be described by differential equations, but only a few of them can be solved explicitly with solutions in formulas.

Common ground

This is the motivation for developing numerical equations to find approximate solutions.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
