Francis Clauser

Francis H. Clauser (BS '34, MS '35, PhD '37), the Clark Blanchard Millikan Professor of Engineering, Emeritus, passed away on March 3, 2013, at age 99. Born in the decade following the Wright Brothers' first powered flight, he was a founder of modern aeronautics and helped usher in the Space Age.

Creating Indestructible Self-Healing Circuits

Imagine that the chips in your smart phone or computer could repair and defend themselves on the fly, recovering in microseconds from problems ranging from less-than-ideal battery power to total transistor failure. It might sound like the stuff of science fiction, but a team of Caltech engineers, for the first time ever, has developed just such self-healing integrated chips.

Under the Hood of the Earthquake Machine

What makes an earthquake go off? Why are earthquakes so difficult to forecast? Professor of Mechanical Engineering and Geophysics Nadia Lapusta gives us a close-up look at the moving parts, as it were, at 8:00 p.m. on Wednesday, February 13, 2013, in Caltech's Beckman Auditorium. Admission is free.

Murray and Ortiz Elected to the National Academy of Engineering

Richard M. Murray and Michael Ortiz of the California Institute of Technology (Caltech) have been elected to the National Academy of Engineering, an honor considered among the highest professional distinctions that an engineer can receive. In total, the academy welcomed 69 new American members and 11 foreign associates this year.

Creating New Quantum Building Blocks

Laying the groundwork for an on-chip optical quantum network, a team of researchers, including Andrei Faraon from the California Institute of Technology (Caltech), has shown that defects in diamond can be used as quantum building blocks that interact with one another via photons, the basic units of light.

Jorgensen Laboratory Awarded LEED Platinum Certification

The recent renovations of the Jorgensen Laboratory included many upgrades that were designed to reflect Caltech's commitment to sustainability. Now the building has achieved LEED Platinum certification, the highest honor of the U.S. Green Building Council.

Notes from the Back Row: "Engineering with Impact"

If you hit something hard enough, it will break, and the consequences can be catastrophic. A space rock roughly the size of Pasadena killed the dinosaurs when it hit the Earth at about 45,000 miles per hour, but even something as small as a bird hitting a turbine blade can bring down an airplane. The damage occurs in the blink of an eye as unimaginable pressures are fleetingly focused on the hapless chunk of rock or metal. The key to survival is to disperse those forces. But how? Caltech professor Ravi Ravichandran is trying to find out.

TEDxCaltech: Advancing Humanoid Robots

When Matanya Horowitz started his undergraduate work in 2006 at University of Colorado at Boulder, he knew that he wanted to work in robotics—mostly because he was disappointed that technology had not yet made good on his sci-fi–inspired dreams of humanoid robots. "The best thing we had at the time was the Roomba, which is a great product, but compared to science fiction it seemed really diminutive," says Horowitz. He therefore decided to major in not just electrical engineering, but also economics, applied math, and computer science. "I thought that the answer to better robots would lie somewhere in the middle of these different subjects, and that maybe each one held a different key," he explains. Now a doctoral student at Caltech—he earned his masters in the same four years as his multiple undergrad degrees—Horowitz is putting his range of academic experience to work in the labs of engineers Joel Burdick and John Doyle to help advance robotics and intelligent systems

Faulty Behavior

In an earthquake, ground motion is the result of waves emitted when the two sides of a fault move—or slip—rapidly past each other, with an average relative speed of about three feet per second. Not all fault segments move so quickly, however—some slip slowly, through a process called creep, and are considered to be "stable," or not capable of hosting rapid earthquake-producing slip. One common hypothesis suggests that such creeping fault behavior is persistent over time, with currently stable segments acting as barriers to fast-slipping, shake-producing earthquake ruptures. But a new study by researchers at the California Institute of Technology (Caltech) and the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) shows that this might not be true.
