Seismic experiments provide new clues to earthquake wave directionality and growth speed

In recent years, seismologists thought they were getting a handle on how an earthquake tends to rupture in a preferred direction along big strike-slip faults like the San Andreas. This is important because the direction of rupture has a profound influence on the distribution of ground shaking. But a new study could undermine their confidence a bit.

Caltech fluid dynamics expert wins annual Feynman Award for excellence in teaching

Chris Brennen has many pleasant memories of the "frosh camp" trips he used to make to Catalina Island with famed physicist Richard Feynman. As two California Institute of Technology faculty members who were particularly willing to accompany the new crop of Caltech freshmen on the annual orientation trip, Brennen and Feynman shared various interesting experiences at the rustic Camp Fox.

New light-emitting device could eliminate the bottleneck that slows down electrical circuits

Applied physicists at the California Institute of Technology have invented a light-emitting transistor that could potentially bypass a major bottleneck that slows down electronic circuitry. The new device could pave the way for on-chip optical interconnections that would enable the marriage of two great modern technologies--communications based on the transmission of photons, and computing with silicon-based devices that are driven by electric currents. A successful optical interconnection technology would allow information to move around inside a silicon chip at the speed of light while creating substantially less heat, leading to dramatically faster computers.

Caltech Launches New Information Initiative

The California Institute of Technology has launched a university-wide initiative called Information Science and Technology (IST)--drawing back the curtain on the nature of information itself and redefining the way we approach, understand, and use science and engineering. IST will cut across disciplines, eventually involving over 25 percent of all faculty and nearly 35 percent of students on campus, likely altering the Institute's intellectual and organizational landscape.

Fuel Cells: the Next Generation

Sossina Haile, an associate professor of materials science and chemical engineering at the California Institute of Technology, is an expert in fuel cells, and she has been whittling away at the heat problem for years. Now she and her colleagues have not only solved the problem, they've smashed it. They've brought the temperature down to about 600 degrees Celsius (1100 degrees Fahrenheit), while achieving more power output than others are achieving at the higher temperatures--about 1 watt per square centimeter of fuel cell area.

National Institutes of Health Name Phillips, Quake as Director's Pioneer Award Winners

The National Institutes of Health (NIH) has announced that California Institute of Technology mechanical engineering and applied physics professor Rob Phillips is one of nine recipients of the first annual Director's Pioneer Award. Stephen Quake, the Thomas E. and Doris Everhart Professor of Applied Physics and Physics at Caltech, currently at Stanford University, is also among this year's recipients.

Science by the Seat of the Pants

Sliding down a sand dune on your derriere might at first take seem a bit undignified for a professor from the California Institute of Technology. But for mechanical engineering professor Melany Hunt, it's all in the name of science.

Jennings Named Caltech Provost

Paul Jennings, professor emeritus in civil engineering and applied mechanics at the California Institute of Technology, has been named provost of the Institute. He takes the post on August 1.

Inaugural Wouk Lecture on Advanced Technology for Space Exploration

Erik Antonsson, the chief technologist at the Jet Propulsion Laboratory and a professor of mechanical engineering at the California Institute of Technology, will give the inaugural Victor Wouk Lecture at 4 p.m. May 19 in Lees-Kubota Lecture Hall, 101 Guggenheim Laboratory of Aeronautics and Applied Science on the Caltech campus. Antonsson will discuss "Advanced Technology for Space Exploration" and will provide an overview of the JPL Strategic Technology Plan, along with highlights of recent successes and future missions. A wine and cheese reception will follow. The program is free and open to the public.

White House Names Three from Caltech Faculty as Presidential Early Career Award Winners

Three members of the faculty at the California Institute of Technology have been named among the most recent winners of the prestigious Presidential Early Career Award for Scientists and Engineers (PECASE). The honor was announced today by the White House.
