FUTURE Ignited

11-04-20

Nearly 200 undergraduates from more than 120 colleges and universities across the country joined Caltech for FUTURE Ignited, a virtual event that aimed to encourage students of color to pursue graduate studies in science and engineering. The goal of FUTURE Ignited is to diversify STEM with students of color who will go on to become incredible graduate students and scientific leaders in their respective fields. [Caltech story]

EAS Remembers Wilfred D. (Bill) Iwan

11-02-20

Wilfred D. (Bill) Iwan, Professor of Civil Engineering, Emeritus, passed away on October 29, 2020. He was 85 years old. Dr. Bill Iwan received all his degrees from Caltech, B.S. in 1957, M.S. in 1958, and Ph.D. in 1961. He joined the Caltech faculty in 1964 and became Professor Emeritus in 2004. He served as the Executive Officer for Civil Engineering and Applied Mechanics, 1980-86. Dr. Iwan’s research focused on fundamental areas of mechanics, understanding and characterization of strong earthquake ground motion, analysis and monitoring of the response of structural systems subjected to extreme events, and public policy regarding disasters. His research achievements include the development of methods to represent complex nonlinear structures with simpler linear systems, the development of practical methods for earthquake-resistant design, and the development of simplified methods for the analysis of seismic isolation systems for critical equipment. In 1979, he proposed an earthquake early-warning system for urban regions. Dr. Iwan was elected to the National Academy of Engineering in 1999 “for research on seismic performance of structures, and for leadership in earthquake hazard mitigation and improvement of public safety.” He was a Distinguished Member and Fellow of the American Society of Civil Engineers (ASCE), which awarded him the Nathan M. Newmark Medal (1997), William H. Wisely Award (2006), and Theodore von Karman Medal (2013). In recognition of his distinguished service, the California Earthquake Safety Foundation awarded him the 2002 Alfred E. Alquist Medal “for his lifetime of service to the profession of structural engineering and its application to the safety of the people of California and the world". [Caltech story]

Ultrafast Camera Films 3-D Movies at 100 Billion Frames Per Second

10-19-20

Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, has developed technology that can reach blistering speeds of 70 trillion frames per second, fast enough to see light travel. Just like the camera in your cell phone, though, it can only produce flat images. Now, Wang's lab has gone a step further to create a camera that not only records video at incredibly fast speeds but does so in three dimensions. [Caltech story]
