In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to a laminar flow, which occurs when a fluid flows in parallel layers, with no disruption between those layers. [1] Turbulent flow is unpredictable, exists on scales from microscopic to cosmic, is diffusive, and dissipative. [2]

"Turbulence is everywhere. It's inside you and around you—from the smallest scales to the largest structures in the universe. And it's useful for flying airplanes, forming raindrops, making golf balls fly further, and helping fish—dead or alive—swim upstream.@Laminar Flow, by contrast, is small and superficial—it's a toy. That's why its most notable use is in decorative fountains. It appeals to your desire for order, but the world—like turbulence—is messy." [2]
