[ExI] The 60-Year-Old Scientific Screwup That Helped Covid Kill

[John Grigg]

"All pandemic long, scientists brawled over how the virus spreads. *Droplets!
No, aerosols!* At the heart of the fight was a teensy error with huge
consequences."

"...There was just one literally tiny problem: “The physics of it is all
wrong,” Marr says. That much seemed obvious to her from everything she knew
about how things move through air. Reality is far messier, with particles
much larger than 5 microns staying afloat and behaving like aerosols,
depending on heat, humidity, and airspeed. “I’d see the wrong number over
and over again, and I just found that disturbing,” she says. The error
meant that the medical community had a distorted picture of how people
might get sick."
