  1. Guest lecturer Rusty Schweickart gives a lecture entitled, "The Asteroid Challenge: Will We Be Ready?" for Professor Lynn Rothschild's Astrobiology and Space Exploration course.

  2. The Tree of Life must be discovered through rigorous analysis. Genetic information is crucial because appearances can be deceiving, and species that look similar can prove to be genetically very dissimilar and not share recent common ancestors. Two criteria, used to determine what the "correct" Tree is, are simplicity and whether the tree maximizes the probability of observing what we actually see.

  3. Rocco L. Mancinelli, a Senior Research Scientist with the Search for Extraterrestrial Life, discusses organisms' potential for survival, adaptation and biological evolution in the atmosphere and beyond to outer space.

  4. Professor Channing Robertson of the Stanford University Chemical Engineering Department discusses scaling, focusing on dimensionless analysis.

  5. Discriminative Algorithms, Generative Algorithms, Gaussian Discriminant Analysis (GDA), GDA and Logistic Regression, Naive Bayes, Laplace Smoothing

  6. Dr. David McKay, Chief Scientist for Astrobiology at the Johnson Space Center, lectures on his scientific experience with meteorites, more specifically ALH 84001.

  7. During its inception, Dell explains how the computer industry was run by engineers. Over a thirty-year period however, customers began to have an important role in the industry, but many companies were still being run by engineers working to promote complexity. With complicated products being sold, says Dell, customers had to rent specialized software and hire consultants from the computer companies to get their products to work. As a resu...more

  8. May 4, 2009 - Leonard Susskind explains the second law of thermodynamics, illustrates chaos, and discusses how the volume of phase space grows.
