John W.M. Bush, an associate professor in mathematics at MIT, has studied the underlying hydrodynamics of the seemingly miraculous feat of walking on water (as some insects do). By using mathematics, high-speed photography, and flow visualization techniques, he discovered something short of a miracle: The insects use one set of legs like oars, sculling their way across the water's surface. A full report is in the August 7 issue of Nature Magazine.
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK.
