Episode notes
Surprising Everyday Fluid Tricks
- Steve Simon shows everyday hydrodynamic surprises like a standing wave that surfers ride in Munich.
- He also highlights a hydrofoil gliding trick that keeps a rider aloft for long distances.
Navier–Stokes Hides Deep Math
- The Navier–Stokes equations look compact but hide deep mathematical challenges in 3D.
- Steve Simon notes existence and uniqueness in 3D remain unsolved and carry a Clay million-dollar prize.
Hydrodynamics Works Across Extreme Scales
- Hydrodynamics applies from quark-gluon plasmas to cold trapped atoms and interstellar gases.
- Steve Simon quantifies this reach as spanning ~20 orders of energy and ~33 orders of length.
