Welcome to Series #2 of the Big Compute Podcast!  Ever wondered how COVID-19 can spread through the air indoors?  Is 6 feet apart enough distance?  Do plexiglass barriers protect us?  We talk to undercover superhero, Jiarong Hong of the University of Minnesota, about his discoveries from simulating the movement of aerosol particles in different indoor spaces and how it can affect our everyday lives.  We also dive into his revealing research about what musical instruments may be spreading the virus more than others, including whether or not tuba concerts are worth the risk during this pandemic.
