...high-tech gizmo in a small, unadorned office in a brick, Industrial Age building in South Boston topped with Hollywood-style letters spelling out WORLD SHAVING HEADQUARTERS. John Terry, the elderly, thick-glassed British engineer whose team came up with the design for the successor to the twin-track Sensor, cradles the prototype between his thumb and forefinger as if it were a Honus Wagner. Terry, who has two degrees in metallurgy, talks about his invention as if it were the fax machine...
...Mach3 will arrive in stores in July, priced at $6.29 to $6.79 for four cartridges, or 35% more than Gillette's Sensor Excel. It will be promoted by a $300 million marketing budget that will include an ad involving a jet producing three sonic booms before morphing into a razor wielded by a guy who looks as if he grows as much facial hair as Matt Damon...
Other experiments include research into wave-guides--a way to guide light and use it for sensor applications. In collaboration with the Westervelt group, also of the Department of Physics, Prentiss' laboratory is creating magnetic mirrors for atoms out of microfabricated wires. These mirrors can be used in atom interferometers, which can act as very sensitive gyroscopes...
...Island, right in the middle of the bay, so Lowe can study them easily. In order to understand how much impact a hammerhead has on the bay ecosystem, Lowe is trying to learn how much energy it expends and how much food that takes. He has designed a miniature sensor that attaches to the baby shark's back and registers every beat of the tail as the shark swims along. By feeding the babies a precise amount of fish, then putting them in a tank with constantly flowing water--a sort of shark treadmill--he can determine just how many...
...second part of the experiment, Lowe puts a sensor-equipped shark into the open bay and follows it as it darts back and forth. After two days of nonstop tracking, he and his exhausted crew have a precise record of where the baby has gone and, by counting its tail beats, how much energy it has used. "We still have a lot of data to gather," he says, "but once we really understand what role the hammerhead pups play here, we can use that to begin understanding how adults fit into the ecosystem of the open ocean...
