Building Infrastructure to Handle Growing Populations
Mechanical Engineering undergraduate student, Eric Chang, has been named a Watson Fellow. The fellowship enables graduating seniors to spend a year traveling around the world, exploring and learning about topics of their choice. Chang will spend about three months each in Taiwan, Shanghai, Hong Kong, and Hyderabad, India. In Asia, more and more people are moving from rural areas to the cities, and these cities must be able to build the infrastructure to handle the new population. "I wanted to see how these problems are being approached in these countries," he says. "These issues are going to have a large impact on the world." [Caltech Feature]
Robots Take Over Millikan Pond
Robots designed and built by undergraduate students battled in head-to-head competition, in this year's ME 72 Engineering Design Contest which was dubbed "The Conquest of Millikan Islands." Teams had to design and build robots to retrieve 11 ping-pong balls from dispensers on the footbridge and then use a second aquatic robot to put those balls into small "islands" distributed around the pond. Finally, after an afternoon of many fierce rounds, team Robotics Anonymous emerged victorious. [Caltech Feature] [ABC7 News Video]
"Hydrodynamics of Pumps" is Now in Japanese, Farsi, and Chinese Translation
Hydrodynamics of Pumps, a book written by Christopher E. Brennen, Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering, Emeritus, which was originally published in 1994 by Oxford University Press and Concepts ETI has now been published in Japanese, Farsi, and Chinese translations. Professor Tsujimoto composed the Japanese translation which was published by Osaka University Press. Most recently Cambridge University Press concluded an agreement with Jiangsu University Press for the publication (in both hardback and paperback) of the translation by Dr. Pan Zhongyong of Jiangsu University.
Light as a Feather, Stiffer Than a Board
Julia R. Greer, Assistant Professor of Materials Science and Mechanics, and colleagues have developed the world’s lightest solid material, with a density of 0.9 milligrams per cubic centimeter. The new material, called a micro-lattice, relies, on a lattice architecture: tiny hollow tubes made of nickel-phosphorous are angled to connect at nodes, forming repeating, asterisklike unit cells in three dimensions. "We're entering a new era of materials science where material properties are determined not only by the microscopic makeup of the material but also by the architecture of the constituents," Greer says.
