Feeling sad for masks in cars; covid commentary/ unscientific movie reviews (Gravity / Dante's peak) 

You will be pleased to know that you repaired a synth used in the making of “I Wear My Face Mask in the Car. You helped me with it about 3/4 years ago.

a facebook comment: Mark Carman Wrong again Bob. The basic reproduction number is assumed to be total number of people one person will infect, not how many that person will infect PER DAY. This basic mistake of yours of course messes up your math too. It’s especially delicious since you were touting your own scientific credentials in the video and then you came off looking dumb. Yours, Mark Like · Reply · 1d · Edited Robert Weigel i got no notification... blame f/b's liberal overlords... Mark i'm making a 'conceptual estimation' technique for 'worst case approximation. It saves time when detailed analysis isn't necessary. They were initially amping this thing like it was highly contagious compared to influenza. Here of course early in the spread of a hyper infectious disease that you don't know you have for weeks at times.....a market vendor or waiter etc. would get it. 4-5 months this ran unchecked. SUCH a person could easily infect 50-100 or more in a day. We were told it's passed as we speak etc.!!! And the next day 40-80 other people. ie. they already got the others they work with. next day 35-70 with some repeat customers.... and perhaps in a few weeks those people are down to infecting only 20 new people a day and then they get ill and isolate. Or some in 5 days or so. Meanwhile those they infected in a few days start infecting others in family and coworkers So basically first real 'people' people who get it may pass it to 1000 before they know they have it. AND IT LIKELY WASN'T LONG after it's introduction someone like that had it... And in days coworkers are spreading it to many also AND.... their families and kids in schools spread things like mad. Within just a few weeks easily 10's of thousands have it and 3^n would be 60,000 so FOR an off the top worst case growth rate approximation not bad. Some people infect many more for their time infecting others. I'm usually pretty close to what i'm trying to approximate w/out fleshing it out when i put out an estimate like that...practice practice....
