I realize we are all busy, but I enclose a recent picture from the CDC of the corona virus. The problem is that most Fortran programmers are older, so it is a real problem for us older gentle folk.
PS: Vodka only has 40% alc, you need 60% to sterilize.
Interesting problem: How could you encode the nasty little blighter in Fortran?
I was looking at the disease spread models, the problem is similar to the how many bombs does it take to destroy a city - solved by the English Statistician in WW2. Great paper.
In looking at a disease model in Fortran -- it is not a good idea to use the model of a cell enclosed by eight cells, after all human move, I wonder if a good model would include a high level array to code cities, an array below each city for the districts, and so on? In Lisp we could do this in tree and branch form - but it is harder in Fortran
This is just a thought experiment. I realize it has probably been done.
