of models

yesterday I have to give some advise on Covid and while I was talking I said to myself, “you re not anexpert why would you do that” and I answered to myself that “I ve read thinks from good sources, I have checked facts, I have a model of the pandemia in my mind and I believe it is true”

So I felt the urge to reread something I had read sometimes ago in Douglas Hoftadter Strange Loopes and I went looking for it and was the story on Simmballism, SImms and Careenium the billiard pool with vibrating edges

and yes, this is what I needed to read to feel good about models, my belief do not have to be justified alla the way down to single evidences and experiments
