Concluding title slide: Putting us on the Path to Wisdom. A collage contains the following images.
1.) Turbulence on the sun. "This image shows both dim and bright features of the sun's corona, which is formed by interaction of solar turbulence and magnetic fields. It is a composite of three different exposures from the Soft X-ray Telescope from the Yohkoh satellite." This research is led by Juri Toomre and Nic Brummell, University of Colorado, Boulder, National Center for Atmospheric Research. Toomre leads the National Science Foundation High-Performance Computing and Communications Grand Challenge project in geophysical and astrophysical turbulence. The researchers have used the Pittsburgh Supercomputer Center for simulations.
2.) The abstract image demonstrates Walrus, a tool for interactively visualizing large directed graphs in three-dimensional space. Walrus is being developed by Young Hyun at CAIDA, the Cooperative Association for Internet Data Analysis, based at the San Diego Supercomputing Center and partially funded by NSF. The image, a three dimensional sphere with connected data points, is simply intended to give a feel for what visualization and navigation in Walrus are like. The data shown are not necessarily meaningful in themselves.
3.) John Dubinski of the University of Toronto and Lars Hernquist of the Harvard-Smithsonian Center for Astrophysics simulated an encounter between the Milky Way and the Andromeda galaxy on NPACI’s Blue Horizon. This image shows the galaxies colliding about 4 billion years in the future. The image appears on the cover of Envision, 2000; Vol. 16 #1, Jan-March. Envision is a publication of NPACI and SDSC, both funded by the National Science Foundation.
4.) Plant–microbe interactions: Shared roots to symbiosis
The image is an electron micrograph of root hairs of Lotus japonicus, two entwined in response to inoculation with the bacterial symbiont Mesorhizobium loti. Root hairs twist when nitrogen-fixing bacteria take up residence. Researchers Silke Stracke and colleagues have identified a protein that allows some plants to exchange nutrients with microorganisms.
