What do you see

Sitting by the river
watching the water flow by
Swirls and eddies drifting past
pushed by the current
Islands of calm floating by
like floes of ice

Do you see bubbles of water
pushed up from below?
The currents of water
colliding with the flow?

Spinning whirlpools bumping against each other
and then disappearing,
merging into the current

Equations that describe the flow and turbulence
Numbers and symbols superimposed on the swirls
Like having double vision

What do you see?
