James Conca - I have been a scientist in the field of the earth and environmental sciences for 31 years, specializing in geologic disposal of nuclear waste, energy-related research, subsurface transport and environmental clean-up of heavy metals. I have found that important societal issues involving science and technology are rarely made on the basis of science, but on people's perception of science. Science is necessary but insufficient. It seems to be more important to understand Fareed Zakaria than Stephen Hawking, although you better understand both if you want to solve issues like sustainable energy development.
