Vision, Ethics, Passion, Transformation —The Shaping of a Leader in Aerospace
Engineering at Caltech. Two 2007 ME72contestants are shown, Jeff Kranski and Tony Kelman, making last-millisecond adjustments to their machines. The lattice figure is from research by current PhD student Vikram Gavini (MS ‘04). It depicts the hierarchy of triangulations that form the basis of a new method (called QC-OFDFT) for conducting electronic structure calculations at continuum length scales. This method probes the quantum-mechanical...
