Philip G. Saffman Graduate Fellowship Established
Mrs. Ruth Saffman, in memory of her late husband, Theodore von Kármán Professor Emeritus, Philip G. Saffman (1931-2008), has established the Philip G. Saffman Endowed Graduate Fellowship in Engineering and Applied Science in the area of mechanics. "Philip Saffman was one of the leading figures in fluid mechanics and a giant in the field of vortex dynamics and its applications... His work continues to motivate and influence contemporary research in fluid dynamics, which attests to the power of his pioneering ideas." Said EAS Division Chair G. Ravichandran. The first recipient of the Saffman Fellowship is GALCIT graduate student Nicholas White.
Future Electronics May Depend on Lasers, Not Quartz
Kerry Vahala, Ted and Ginger Jenkins Professor of Information Science and Technology and Applied Physics as well as the Executive Officer for APhMS, and colleagues have developed a method to stabilize microwave signals in the range of gigahertz, or billions of cycles per second—using a pair of laser beams as the reference, in lieu of a quartz crystal. "There are always tradeoffs between the highest performance, the smallest size, and the best ease of integration. But even in this first demonstration, these optical oscillators have many advantages; they are on par with, and in some cases even better than, what is available with widespread electronic technology," Vahala says.
