FLOW: A Beautiful Vortex Is Only the Beginning
A picture invites belief. An experiment earns a narrower claim. Where FLOW begins, and where the mathematical question stays separate.

Inside FLOW
Follow the ink. Question the picture. From one gesture to a fair comparison, from a beautiful vortex to the dye it quietly lost — ten explorations of fluid motion and the evidence behind it.

FLOW: The Ink Is Not the Fluid
Erase the dye and the flow can keep moving. Separate the carrier, the tracer and the gesture that started everything.

FLOW: What Viscosity Changes—and What It Does Not
Momentum smooths out. Ink has its own diffusivity. One exact wave makes the distinction measurable.

FLOW: The Picture Looked Right. The Dye Was Disappearing.
A ten-unit run lost 5.115% of its dye. Keep the failed observation, change the transport method, measure again.
