Fast Company – “Keep six feet of distance. Issued by the Centers for Disease Control and Prevention and adopted by many businesses, it’s the guideline that most of us have lived by during COVID-19. But as the climate has turned cold and some of us have moved indoors, John Bush, a professor of applied mathematics at the Massachusetts Institute of  Technology, calls such a rule of thumb “dangerous” and “overly simplistic.” Because when you’re inside, microscopic droplets are trapped right alongside you in a confined space, and standing six feet away from someone doesn’t stop the SARS-CoV-2 virus from floating in the air of your living room where you can potentially inhale it. So are any of us safe indoors during the COVID-19 era? Can we go to a grocery store? Can we meet with a loved one? Bush, alongside his MIT colleague Martin Z. Bazant, have answered that question with a complex mathematical model, which simulates the fluid dynamics of virus-loaded respiratory droplets in any space, from a cozy kitchen to a gigantic concert hall…”
