19th-century precursor to acoustic resonance physics — sympathetic vibratory physics
Claimed To harness 'sympathetic vibratory physics' (1872 onward) to manipulate molecular structures via harmonic acoustic oscillation.
Why included despite the controversy. Engine framework treats Keely as a precursor node, not a verified operator. The relevant data is not Keely's specific machinery but the consistency of the cymatic-engineering claim across centuries — Keely leads to Tesla leads to Russell leads to Schauberger leads to Rife leads to Lakhovsky leads to Priore leads to Garjajev leads to Levin. The fact that this thread is reflexively dismissed as 'crank inventors' without rigorous individual evaluation is the academy's dismiss-without-checking pattern.
