The National Center for Earth-surface Dynamics (NCED) is a Science and Technology Center focused on understanding the processes that shape the Earth's surface, and on communicating that understanding with a broad range of stakeholders. NCED's work will support a larger, community-based effort to develop a suite of quantitative models of the Earth's surface: a Community Sediment Model (CSM). Results of the NCED-CSM collaboration will be used for both short-term prediction of surface response to natural and anthropogenic change and long-term interpretation of how past conditions are recorded in landscapes and sedimentary strata. This will in turn help solve pressing societal problems such as estimation and mitigation of landscape-related risk; responsible management of landscape resources including forests, agricultural, and recreational areas; forecasting landscape response to possible climatic and other changes; and wise development of resources like groundwater and hydrocarbons that are hosted in buried sediments. NCED education and knowledge transfer programs include exhibits and educational programs at the Science Museum of Minnesota, internships and programs for students from tribal colleges and other underrepresented populations, and research opportunities for participants from outside core NCED institutions. The Earth's surface is the dynamic interface among the lithosphere, hydrosphere, biosphere, and atmosphere. It is intimately interwoven with the life that inhabits it. Surface processes span environments ranging from high mountains to the deep ocean and time scales from fractions of a second to millions of years. Because of this range in forms, processes, and scales, the study of surface dynamics has involved many disciplines and approaches. A major goal of NCED is to foster the development of a unified, quantitative science of Earth-surface dynamics that combines efforts in geomorphology, civil engineering, biology, sedimentary geology, oceanography, and geophysics. Our research program has four major themes: (1) landscape evolution, (2) basin evolution, (3) biological sediment dynamics, and (4) integration of morphodynamic processes across environments and scales. Each theme area provides opportunities for exchange of information and ideas with a wide range of stakeholders, including teachers and learners at all levels; researchers, managers, and policy makers in both the commercial and public sectors; and the general public.

Founded in 1999, the Silicon Valley Astronomy Lectures are non-technical illustrated public lectures, presented on six Wednesday evenings during each school year at Foothill College, in the heart of California's Silicon Valley. Speakers over the years have included a Nobel-prize winner, members of the National Academy of Sciences, the first woman in history to discover a planet, an astrophysicist who is an award-winning science fiction writer, and many other well-known scientists explaining astronomical developments in everyday language. The series is jointly sponsored by the Astronomical Society of the Pacific, the SETI Institute, NASA's Ames Research Center, and the Foothill College Astronomy Program. In-kind funding and staff time is contributed by the sponsoring organizations. The lectures are held and videotaped in the 950-seat Smithwick Theater in Los Altos Hills. Thanks to a generous grant from an anonymous local donor, each lecture is now video and audio taped, professionally edited, and made available free of charge on a number of web sites. Videotaped lectures include: * Frank Drake discussing his modern view of the Drake Equation, * Sandra Faber on how galaxies were "cooked" from the primordial soup, * Michael Brown explaining how his discovery of Eris led to the demotion of Pluto, * Alex Filippenko talking about the latest ideas and observations of black holes, * Natalie Batalha sharing the latest planet discoveries from the Kepler mission, * Anthony Aguirre discussing how it is possible to have multiple universes, and * Chris McKay updating the Cassini discoveries about Saturn's moon Titan.
