Producing Squeezed Light Using a Silicon Micromechanical System

08-07-13

Oskar J. Painter, Professor of Applied Physics, and colleagues have produced squeezed light using a silicon micromechanical system. "This system should enable a new set of precision microsensors capable of beating standard limits set by quantum mechanics," says Professor Painter. "Our experiment brings together, in a tiny microchip package, many aspects of work that has been done in quantum optics and precision measurement over the last 40 years." [Caltech Release]

Developing Self-replicating Nanoscale Origami

08-06-13

William A. Goddard III, Charles and Mary Ferkel Professor of Chemistry, Materials Science, and Applied Physics, and colleagues including Postdoctoral Scholar Si-ping Han have been awarded a $2 million grant as part of the National Science Foundation’s Origami Design for Integration of Self-assembling Systems for Engineering Innovation program. The funds will be used to develop biomimetic materials which contain assembled complexes of molecules that self-replicate, evolve and adopt intricate three dimensional structures at the nanometer scale by combining DNA guided self-assembly with origami folding.

KNI Welcomes New Co-Directors

07-11-13

Founding Kavli Nanoscience Institute (KNI) Board member Professor Nai-Chang Yeh, and KNI Board member Professor Keith Schwab have been appointed to serve as the newly endowed Fletcher Jones Foundation co-directors of the KNI for a 3 year term. "The KNI is a thriving organization serving many researchers on (and off) campus, and I look forward to the energy and creativity that Nai-Chang and Keith will bring to the continued evolution of the KNI as a preeminent organization propelling nanoscience forward in diverse application areas ranging from medical engineering to nanophotonics," says Chair Ares Rosakis. Professors Yeh and Schwab follow in the footsteps of Professors Michael Roukes and Oskar Painter, who have finished a productive tenure in the position as co-directors and are thanked for their tenacity, vision, and leadership.

Otis Booth Leadership Chair Established at Caltech

07-03-13

With a $10 million gift, the Los Angeles–based Otis Booth Foundation has created and endowed the Otis Booth Leadership Chair for the Division of Engineering and Applied Science (EAS) at Caltech. "The first funds from the endowment will support time-sensitive research that is too high risk for most traditional grants," says Chair Ares Rosakis, the inaugural holder of the Booth Leadership Chair. "I am excited to see what inventions and ideas become realities as Dr. Rosakis and his successors at the helm of EAS use this endowment now and far into the future," says Lynn Booth, president of the Otis Booth Foundation, a Caltech trustee, and a prominent Los Angeles philanthropist.

Professor Roukes Honored by the French Republic

06-28-13

Michael L. Roukes, Robert M. Abbey Professor of Physics, Applied Physics, and Bioengineering, has received the Chevalier de l'ordre des Palmes Académiques, which is the Knight grade of the French Republic's Order of Academic Palms. Founded by Napoleon in 1808 to honor educators and scholars, this distinction recognizes eminent personalities who have made significant contributions to the development of French culture, science, and education. The Consul General of France in Los Angeles, Axel Cruau, presented Professor Roukes with the medal and in his remarks he cited Roukes's collaborations with French research institutions and noted his instrumental role in helping to start the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative, a national program proposed by President Barack Obama to build a comprehensive map of activity in the human brain.

119th Commencement Ceremony

06-14-13

Caltech's 119th Commencement Ceremony was held on Friday, June 14th, 2013 celebrated the accomplishments of 588 graduates, awarding 256 bachelor's degrees, 96 master's degrees, 2 engineer degrees, and 236 doctoral degrees. The graduates were addressed by the University of Michigan president Mary Sue Coleman. She used the life and career of Caltech alumnus Frank Robert Capra, one of America's most powerful directors during the 1930s and the directory of It's a Wonderful Life (1946), to inspire the graduating students. She emphasized the main message of the movie "that each of us touches more than we can appreciate". [Facts about the class of 2013]
