That's the coefficient of variation. Three atomic species. A twelve-to-one mass ratio. Rubidium-87, sodium-23, lithium-7-atoms that differ in mass by a factor of twelve, in scattering length, in healing length, in sound speed, in every physical property that textbooks say should matter. Same critical velocity ratio. Every single time. Not close. Not within experimental error. Identical.

The atoms didn't know they were supposed to behave differently. They only knew geometry.

Superfluid presents the discovery that five of the hardest unsolved problems in mathematics and physics-the Poincaré conjecture, the Yang-Mills mass gap, Navier-Stokes regularity, Bose-Einstein condensate critical velocity, and P NP-are not five problems. They are one problem in five languages. One equation governs them all:

C = τ / K

Capacity equals tolerance divided by curvature. Every transition from smooth to rough-from laminar flow to turbulence, from superfluid to vortex chaos, from efficiently solvable to exponentially hard-obeys this law. The equation is not a metaphor. It is a precise mathematical relationship, validated against experiment, that governs critical phenomena across domains that have never been connected before.

The core insight is structural.

Curvature is obstruction. The same geometry that prevents a superfluid from nucleating vortices is the same geometry that prevents Navier-Stokes solutions from blowing up. The same curvature barriers that make 3-SAT exponentially hard are structurally identical to the barriers that create the Yang-Mills mass gap. The problems were never separate. The disciplines were.

For over a century, topologists didn't talk to gauge theorists. Analysts didn't talk to geometers. Complexity theorists didn't talk to condensed matter physicists. Five communities, five vocabularies, five conferences-all working on the same underlying structure without knowing it.

This book will change how you think about:

- Why Landau's critical velocity was right about the wrong question
