Why Face Masks Work - Eberhard Bodenschatz

Explore the physics behind face mask effectiveness in preventing COVID-19 and other airborne diseases in this comprehensive lecture by Eberhard Bodenschatz from the Max Planck Institute for Dynamics and Self-Organization. Delve into the formation of pathogen-containing particles, the impact of social distancing and masking on transmission risk, and the results of experimental studies on exhaled particle size distribution. Learn about the upper bound of SARS-CoV-2 transmission risk in one-to-one exposure scenarios and discover how appropriate mask usage can provide excellent protection for both wearers and others, potentially eliminating the need for social distancing. The lecture covers topics such as drops and aerosols, risk of SARS-CoV-2 transmission, mask effectiveness with demonstrations, exposure upper bounds, and even the implications for wind instruments. Conclude with a Q&A session moderated by KITP Director Lars Bildsten, offering further insights into this crucial area of public health research.
