7 minute video explains the mathematics of mask effectiveness, making clear how powerful they can be against spreading Covid-19

This short video from the team at minutephysics does a great job showing how the more people wear masks, the more we help beat Covid-19. Another good one is on sensitivity of tests and testing in general. Yay for science! Wear a mask, watch your distance, wash your hands, and get vaccinated as soon as you can. Do your best to help, please and thank you. As of this morning: 24.5 million confirmed cases in the US and over 406,000 dead Americans.
