First, read the following lines from Philip Ball — “What makes [fluid dynamics] so complicated is that each part of the flow depends on what all the other parts are doing. When the flow is turbulent, this interdependence is extreme and the flow becomes chaotic, in the technical sense that the smallest disturbances at one time can lead to completely different patterns of behavior at a later moment.”

Now, mess around with this beautiful, interactive Fluid Dynamics visualization by George Corney (click image). 😲
