  5. A Continuum is Emerging • All information is becoming digital • Computing is becoming • Ubiquitous used everywhere • Continuous interconnected • Pervasive invisible to the user

  6. Human Performance is Finite An individual can absorb about one gigabyte of information per second (1 GB/s). Most of this information is visual.

  7. Human Performance is Constant HUMAN PERFORMANCE TIME

  8. Low-End Computing...

  9. High-end Computing

  10. Changing How Science is Done • Collect data from digital libraries, laboratories, and observation • Analyze the data with models run on the grid • Visualize and share data over the Web • Publish results in a digital library

  17. From Entertainment to Science • Entertainment • Education • Communication • Public Policy • Business • Engineering • Science

  18. Looking out for San Diego’s Regional Ecology • Unique partnership • 31 federal, state, regional,and local agencies • John Helly, et al., SDSC • Combines technologies and multi-agency data • Sensing, analysis, VRML • Physical, chemical, and biological data • Web-based tool for science and public policy

  19. Collaboration with Hayden Planetarium American Museum of Natural History Support from NASA MPIRE Galaxy Renderer Scalable volume visualization Linked to database of astronomical objects Produces translucent, filament-like objects An artificial nebula, modeled after a planetary nebula Digital Galaxy Viewing the Orion Nebula

  20. How do the laws of the physical world apply to cyberspace? Analogies Ambiguity Contradictions Erroneous Assumptions Misperceptions

  21. Behavioral Constraints @Lawrence Lessig Laws Markets Culture Architecture

  22. Ethical vs. Unethical Legal vs. Illegal Right vs. Wrong Moral vs. Immoral Just vs. Unjust Honorable vs. Dishonorable Fair vs. Unfair

  23. What? Why? How? When? Where?

  24. What is the threat? What are we protecting against? Denial of Service Vandalism / Malicious Mischief Theft of Service Theft of Intellectual Property Data Corruption Privacy Violation Attacks on Public Health/Safety/Morality
