Randy Pausch
Pausch delivered his "Last Lecture", titled "Really Achieving Your Childhood Dreams", at CMU on September 18, 2007. He gave an abridged version of his speech on "The Oprah Winfrey Show" in October 2007. The talk was modeled after an ongoing series of lectures where top academics are asked to think deeply about what matters to them, and then give a hypothetical "final talk", with a topic such as "what wisdom would you try to impart to the world if you knew it was your last chance?" Before speaking, Pausch received a long standing ovation from a large crowd of over 400 colleagues and students. When he motioned them to sit down, saying, "Make me earn it", someone in the audience shouted back, "You did!"
Banachek
Banachek first came to public attention as a teenager for his role in James Randi's Project Alpha experiment, which exposed the lack of objectivity in parapsychology research. As director of the One Million Dollar Paranormal Challenge conducted by the James Randi Educational Foundation (JREF), he has since tested the authenticity of many self-described psychics, none of whom has managed to pass scientifically controlled tests of their claimed paranormal abilities.
