U.S. and British researchers claim to have found a better explanation for the wobble of London's River Thames Millennium pedestrian suspension bridge than the one prevailing for over 20 years. Alarming swaying of the bridge was caused not by synchronization of walkers' footsteps, as previously believed, but the negative damping effect of their efforts not to fall over.
