Toward a Smarter Grid
The power network of the future—also known as the smart grid—will have to be much more dynamic and responsive than the current electric grid, handling tremendous loads while incorporating intermittent energy production from renewable resources such as wind and solar, all while ensuring that when you or I flip a switch at home or work, the power still comes on without fail. An interdisciplinary group of engineers, economists, mathematicians, and computer scientists, including Professors Steven Low and Adam Wierman are working to develop the devices, systems, theories, and algorithms to help guide this historic transformation and make sure that it is properly managed.

Dr. van Zyl Receives Honorary Doctorate
Dr. Jakob J. van Zyl (PhD ’86 EE), Caltech Senior Faculty Associate in Electrical Engineering and Aerospace, as well as the Associate Director of Project Formulation and Strategy at JPL, will receive an honorary Doctor of Engineering (DIng) degree from Stellenbosch University in South Africa. Dr. van Zyl was born in Outjo, Namibia and received his first degree in electrical engineering from the University of Stellenbosch . He then came to Caltech where he obtained his Masters and PhD in electrical engineering.

Atomic Fractals in Metallic Glasses
Julia R. Greer, Professor of Materials Science and Mechanics, and colleagues including graduate student David Chen have shown that metallic glasses has an atomic-level structure although it differs from the periodic lattices that characterize crystalline metals. "Our group has solved this paradox by showing that atoms are only arranged fractally up to a certain scale," Greer says. "Larger than that scale, clusters of atoms are packed randomly and tightly, making a fully dense material, just like a regular metal. So we can have something that is both fractal and fully dense."
