Five Hundred Years of Convergence: Leonardo da Vinci's Observations on Cardiac Vortex Flow, Water Spirals, Flying Machine Design, and Sfumato as Prior Evidence for the V=N/D Density Wave Model (v3)

Revised v3: Section 4b strengthened with comparative analysis establishing Leonardo's prior art claim for ephemeralization. Three simultaneous conditions documented (systematic biological study + explicit principle extraction + engineering application) distinguish Leonardo from contemporaries Brunelleschi, Alberti, and di Giorgio Martini. All five convergences now include falsification criteria.

Abstract

Revised v3: Section 4b strengthened with comparative analysis establishing Leonardo's prior art claim for ephemeralization. Three simultaneous conditions documented (systematic biological study + explicit principle extraction + engineering application) distinguish Leonardo from contemporaries Brunelleschi, Alberti, and di Giorgio Martini. All five convergences now include falsification criteria.
