[FRIAM] All models are wrong - modeling Covid-19

Could anybody have been in any doubt that those weren’t my words?

If there is such a person, I am honored by their confusion. 

 

By the way, what is this “reality” that the author is talking about, speaking of physics’ s need for philosophy.  And while I am in and being grumpy, Steve, speaking as a lifetime bird researcher, I can assure you that birds could make good use of ornithology if it were available to them.  I am truly, TRULY, bothered by the Feynman cult.  That’s a terrible quote.

Well, I love the idea that all the QM hocus pocus could just boil down to round off.   Your "free will" is truncation error.  Oops.   (Funny contrast with the last episode of Devs.)

To be clear, the below aren't Nick's words, they're cut-n-paste from the paper.

I argue that a finite volume of space can’t contain more than a finite amount of information, hence that the mathematical real numbers are not physically relevant. Moreover, a better terminology for the so-called real numbers is “random numbers”, as their series of bits are truly random. I propose an alternative classical mechanics, which is empirically equivalent to classical mechanics, but uses only finite-information numbers. This alternative classical mechanics is non-deterministic, despite the use of deterministic equations, in a way similar to quantum theory. Interestingly, both alternative classical mechanics and quantum theories can be supplemented by additional variables in such a way that the supplemented theory is deterministic. Most physicists straightforwardly supplement classical
> theory with real numbers to which they attribute physical existence, while most physicists reject Bohmian mechanics as supplemented quantum theory, arguing that Bohmian positions have no physical reality.
