Antimatter is just like matter with all its properties reversed. Scientists think there may have been equal amount of matter and antimatter in the early universe, and yet today we have lots of matter and very little antimatter. How and when that imbalance developed is one of the great mysteries in understanding the underlying properties of the universe. Dr. Quinn, Professor of Physics at the Stanford Linear Accelerator and co-author of a popular book on antimatter, discusses the history of our understanding of antimatter and how we use the little bit of antimatter around today to study some of the highest energy processes among the stars and galaxies. (This talk is a bit more technical than our usual lectures, but well worth exploring if you are interested in some of the most exciting frontiers of physics.)
