OK, no one (YET) has come CLOSE to convincing me of the PC
(Pedagogically Correct!) position that the Tacoma Narrows Bridge is
not an EXCELLENT example of of a resonant oscillation driven by
vortex shedding. Yes, death grips ARE hard to release but this seems
to be every bit as much a resonance phenomenon as many others
(including the particle resonances).
