He is involved in the DEAP-3600 liquid argon experiment and the PICO experiment at SNOLAB, both of which are looking for dark matter. In this episode, Dr. Noble explains how the field of particle astrophysics came to be, and gives the example of the solar neutrino problem where scientists were trying to understand the basic properties of one of the most ubiquitous particles in the universe. There are a billion neutrinos going through your thumbnail every second! Dr. Noble also explains the history of the SNO project, which was designed to study solar neutrinos, as well as the new projects happening at SNOLAB. Please visit Tony’s website for more information.
