"Big whirls have little whirls that feed on their velocity,
and little whirls have lesser whirls and so on to viscosity."
The poem was inspired by this one by Jonathan Swift.
“So, naturalists observe, a flea
Hath smaller fleas on him that prey
And these hath smaller fleas to bite ‘em
And so proceed ad infinitum.”
The turbulence poem is quite clever as it encapsulates quite well the theory of turbulence. Another cool thing he showed us was this picture by Leonardo da Vinci. Which is quite an amazing drawing.
I find turbulence really quite fascinating and I'm glad that my lecturer showed us these interesting things that are related as it will help me remember what is happening.
