As artificial intelligence becomes mainstream, who will guide it?

12-18-18

In a recent Techer interview Electrical Engineering alumna Fei-Fei Li (PhD ’05) explains, “As we see artificial intelligence impacting the real world, it’s no longer a niche computer science, technical field. Policymakers, business leaders, educators, social scientists—they all need to take part and guide the future of A.I.” [Check out the full interview]

New Climate Model to Be Built from the Ground Up

12-13-18

"Projections with current climate models—for example, of how features such as rainfall extremes will change—still have large uncertainties, and the uncertainties are poorly quantified," says Professor Tapio Schneider, principal investigator of the Climate Modeling Alliance (CliMA). "For cities planning their stormwater management infrastructure to withstand the next 100 years' worth of floods, this is a serious issue; concrete answers about the likely range of climate outcomes are key for planning." The new climate model will be built by a consortium of researchers led by Caltech, in partnership with MIT; the Naval Postgraduate School (NPS); and JPL, which Caltech manages for NASA. It will use data-assimilation and machine-learning tools to improve itself in real time, harnessing both Earth observations and the nested high-resolution simulations. "The success of computational weather forecasting demonstrates the power of using data to improve the accuracy of computer models; we aim to bring the same successes to climate prediction," says Professor Andrew Stuart.

Microscopic Devices That Control Vibrations Could Allow Smaller Mobile Devices

12-12-18

Chiara Daraio, Professor of Mechanical Engineering and Applied Physics, and colleagues have developed phononic devices that include parts that vibrate extremely fast, moving back and forth up to tens of millions of times per second. The devices were developed by creating silicon nitride drums that are just 90 nanometers thick. The drums are arranged into grids, with different grid patterns having different properties. Professor Daraio, along with former Caltech postdoctoral scholar Jinwoong Cha, have shown that arrays of these drums can act as tunable filters for signals of different frequencies and can act like one-way valves for high-frequency waves.

Caltech President’s 2018 End of Year Message

12-11-18

President Thomas F. Rosenbaum’s end of the year message to the Caltech community highlights the InSight spacecraft landing and the celebration of Frances Arnold’s 2018 Nobel Prize in Chemistry. He states, “these recent events … underscore the extraordinary technological acumen that is necessary to realize the implications of big ideas. The Institute is known throughout the world for its mastery of fundamental science, but it is the connection of these fundamental precepts to engineering innovation that sets Caltech apart.” [Read the full message]

Alumnus to Exploring Ways to Tackle California’s Housing Crisis

12-07-18

Caltech has awarded the inaugural Milton and Rosalind Chang Career Exploration Prize to EAS undergraduate alumnus, Sean McKenna (BS ’17, ACM) for his proposed project “Exploring Ways to Tackle California’s Housing Crisis.” McKenna plans to spend the next year connecting with residents, housing developers, homeless shelters, technology innovators, and policymakers in California and Washington, DC to learn more about the roots of the housing crisis. He is grateful for the “incredible amount of freedom" the Chang Prize will give him "to figure out how the skills and passions I developed at Caltech might translate into making a difference in the housing crisis, a problem that is very real for me, other Techers, and all residents of California.” [Alumni Association story]

The Big Picture

12-03-18

Thanks to Professor Pietro Perona and his graduate students including Grant Van Horn and Sara Beery, the next wildlife photo you snap might set you on a path to helping map life on Earth. “The whole web, this huge repository of wonderful information, is indexed by words,” Perona says. “But when we have an image—a visual query—we don’t know what to do unless there is an expert next to us. We’ve gotten so numb to the idea that we’ll never find the answer out.” [Breakthrough story]
