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.
Sensor deployment in automated factories should be done slowly and conservatively, otherwise engineers may face the loss of hundreds of thousands or even millions of dollars, an Internet of Things expert will tell attendees at the upcoming Design & Manufacturing Show in Minneapolis.
