Content Summary

Collaborating with Marcantonio della Torre (1508–1511), Leonardo performed over 30 dissections to map the vascular system. He also pioneered botanical rules, defining branch scaling as a fractal process.

Technical Deep-Dive

He discovered vortices in the Sinus of Valsalva that close the aortic valve—confirmed by 2014 MRI studies. He formulated the "Rule of Trees" ($D^2 = \sum d_i^2$), though 2023 PNAS studies show this breaks down in 3D hydraulics.

Evidence Ledger

Windsor RL 19083 (aortic vortices); Manuscript G (phyllotaxis).

Agent Hook

Analyze 2023 findings on hydraulic resistance to refine his scaling formulas.

Cross-Reference Mapping

Heart vortices (1512) mirror the geometry of river eddies (1508) and hair curls.

Uncertainty Markers

Cardiac sketches; Botanical realism; Potential impact if published in 1515.
