Context: Dave has a great resume for doing this type of program : lecturer at the Morrison Planetarium , and the California Academy of Sciences . Program Director of the East Bay Astronomical Society at Chabot Space and Science Center in Oakland . But mostly Dave is " crazy scientist man " to me ... a person so passionate about his topic that every adult I spoke with last Saturday did n't know whether to be alarmed or amazed . We all settled on amazed .
