Pesch & Plail's 2012 history narrates Cold War optimal control as two 'corners' — American (Hestenes/Isaacs/Bellman) and Soviet (Pontryagin, fed by Fel'dbaum) — without documenting contact between them

Fel'dbaum didn't just get co-cited with Pontryagin — his engineering work personally catalyzed the maximum principle

Bipartite hop: Helen Gill's 2006 'cyber-physical systems' coinage and Qian Xuesen's 1962 China cybernetics lab — common root, asymmetric descent

The vault's cosine-0.83 pairing between Helen Gill's 2006 CPS coinage and Qian Xuesen's 1962 China cybernetics lab is an embedding false friend: both trace to Wiener, at sharply asymmetric distances
