Café Scientifique with Dr. Priscilla Cushman, on "Dark Matter: Seeing the Invisible Universe" Recorded at the Bryant Lake Bowl on 11-20-12. Here is the description offered for the talk: "We used to think we understood what everything was made of, from the quarks inside protons and neutrons to the stars and galaxies. We call this the Standard Model. However, over the last couple decades, it has become obvious that a class of new elementary particles (called dark matter) make up 80% of the stuff of the Universe. Tonight, Dr. Priscilla Cushman will talk about what dark matter is, why we think it is there, and how we might detect it here on Earth, as we pass through the cloud of dark matter that makes up most of our galaxy. Dr. Cushman graduated A.B. cum laude in Physics and Philosophy from Harvard University in 1976, and earned her Ph.D. in Physics from Rutgers University in 1985. She is a member of the faculty of the School of Physics and Astronomy at the University of Minnesota. Her research is in particle physics, most recently as co-spokesman of the Cryogenic Dark Matter Search currently running in the Soudan Mine in northern Minnesota."
