Complete video at: fora.tv Tom Murphy, associate physics professor at the University of California San Diego, projects energy needs for future enerations to argue that current ways of living are unsustainable. Disputing the argument that technology can save humanity from a peak oil crisis, Murphy states, "the fossil fuel joyride that we have experienced has clouded our judgment." ----- RETHINKING SUSTAINABILITY Growth has an Expiration Date Tom Murphy, Associate Professor of Physics, University of California San Diego Compass Summit, a forum for true interaction and exchange, examines some of today's most pressing problems through the lens of global citizenship, recognizing that human ingenuity is an unlimited resource. Guided by NPR's Ira Flatow, an intimate group of some of the world's best thinkers and doers convened along the rugged Palos Verdes coastline on Oct 23-26, 2011 at Terranea Resort to engage in meaningful conversation, ask questions, and challenge ideas -- we invite you to join in the conversation. Tom Murphy is an associate professor of physics at the University of California, San Diego. He currently leads a project to test General Relativity by bouncing laser pulses off of the reflectors left on the Moon by the Apollo astronauts, achieving one-millimeter range precision. Murphy's keen interest in energy topics began with his teaching a course on energy and the environment for non-science majors at UCSD. He has explored the quantitatively convincing case ...
