Electrical Engineering Alumnus Harold Rosen Passes Away

01-31-17

Harold Rosen (PhD '51, Electrical Engineering), the father of geostationary satellite communications, passed away on January 30, 2017. His Caltech education, he told a Caltech publication in 2012, "gave me such a good grounding in the fundamentals" that he felt capable of attacking any technical problem in almost any field.

Professor Anatol Roshko Passes Away

01-23-17

Anatol Roshko (MS '47, PhD '52), Theodore von Kármán Professor of Aeronautics, Emeritus, at Caltech, passed away on January 23, 2017. Known for his research in several areas of gas dynamics and fluid mechanics, Professor Roshko made contributions to problems of separated flow, bluff-body aerodynamics, shock-wave boundary-layer interactions, shock-tube technology, and the structure of turbulent shear flows. With pioneering aerodynamics researcher Hans Liepmann, he coauthored the widely used textbook Elements of Gasdynamics, published in 1956. [Caltech story]

Tools and Techniques to Track and Study Methane

01-19-17

Methane is less prevalent in the atmosphere than fellow greenhouse gas carbon dioxide (CO2), but it presents more difficult challenges for researchers attempting to study it. Professor Wennberg, is working with colleagues from across Caltech to study methane and its effects on the globe and to pioneer tools and techniques needed to identify, track, and characterize the gas and its sources. One such colleague is Professor Vahala who has paved the way for the miniaturization of high-resolution spectrometers. His new soliton-based system is the basis for a new collaboration with Professor Frankenberg to apply dual-comb spectrometer to methane tracking and analysis. [Caltech story]

Professor Rolf Sabersky Passes Away

11-10-16

Rolf H. Sabersky, Professor of Mechanical Engineering, Emeritus, passed away on October 24, 2016 at the age of 96.  Professor Sabersky joined the faculty in 1949 having obtained his BS ’42, MS ’43, and PhD ’49 from Caltech in Mechanical Engineering. He became professor emeritus in 1988.  He worked with luminaries throughout his distinguished career including Theodore von Kármán at Aerojet. James Van Allan sought his expertise for the development of the Ajax and Bumblebee rocket programs.  Professor Sabersky made pioneering contributions to our understanding of boiling heat transfer, free convection, granular flows, and indoor air quality. He taught courses in thermodynamics, fluid mechanics, and heat transfer.  He was renowned for his commitment to education, mentoring, and promoting diversity. He was the author of two popular textbooks, Elements of Engineering Thermodynamics, and Fluid Flow: A First course in Fluid Mechanics, which he coauthored with Professor Allan Acosta. He received the Heat Transfer Memorial Award from the American Society of Mechanical Engineers in 1977.

Open Online Course on Quantum Cryptography

09-29-16

Thomas Vidick, Assistant Professor of Computing and Mathematical Sciences, is co-teaching a massive open online course (MOOC)—CS/Ph 120, Quantum Cryptography—focused on the ways in which quantum mechanics can be used to create secure lines of communication. "It's a hot topic, but there are very few resources for people wanting to go beyond just the basics. Very few schools will even have a quantum cryptography course," Vidick says.

James J. Morgan Symposium

09-23-16

On Friday September 23rd, 2016 the Environmental Science and Engineering Department hosted a day-long tribute to James J. Morgan, Marvin L. Goldberger Professor of Environmental Engineering Science, Emeritus. The symposium featured a series of presentations by his former students and leaders in the field of aquatic chemistry. Professor Morgan’s teaching and research centered on aquatic chemistry; major themes comprised rates of abiotic manganese oxidation on particle surfaces and flocculation of natural water particles, and chemical speciation proved the key. He came to Caltech as Associate Professor of Environmental Health Engineering in 1965 and became the Goldberger Professor of Environmental Engineering Science in 1987. He has served Caltech in a variety of capacities including Academic Officer for Environmental Engineering Science, Dean of Students, Executive Officer for Environmental Engineering Science, Acting Dean of Graduate Studies, and Vice President for Student Affairs.

Philip G. Saffman Graduate Fellowship Established

02-01-16

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.
