From the Ted Talk by Tomás Chor: Turbulence One of the great unsolved mysteries of physics

Unscramble the Blue Letters

Here’s what we do know. Liquids and gases usually have two types of motion: a lnmaiar flow, which is stable and smooth; and a turbulent flow, which is composed of sgmeliney uniernagozd swirls. Imagine an incense stick. The laminar flow of unruffled skome at the base is steady and easy to predict. Closer to the top, however, the smoke accelerates, becomes unstable, and the pratten of movement changes to something chaotic. That’s turbulence in action, and turbulent flows have certain characteristics in cmmoon.

Original Text

Here’s what we do know. Liquids and gases usually have two types of motion: a laminar flow, which is stable and smooth; and a turbulent flow, which is composed of seemingly unorganized swirls. Imagine an incense stick. The laminar flow of unruffled smoke at the base is steady and easy to predict. Closer to the top, however, the smoke accelerates, becomes unstable, and the pattern of movement changes to something chaotic. That’s turbulence in action, and turbulent flows have certain characteristics in common.
