Cosmo Kramer : Have you ever met a proctologist? Well, they usually have a very good sense of humor. You meet a proctologist at a party, don't walk away. Plant yourself there, because you will hear the funniest stories you've ever heard. See, no one wants to admit to them that they stuck something up there. Never! It's always an accident. Every proctologist story ends in the same way: "It was a million to one shot, Doc. Million to one!"

> "Scientists have calculated that the chances of something so patently absurd actually existing are millions to one. But magicians have calculated that million-to-one chances crop up nine times out of ten." -- Terry Pratchett Making fun of the fact that if someone says "it's a million-to-one chance, but it might just work!" in fiction, you know it's going to work. In _Guards! Guards!_ this is taken to the point that…

The cheese-loving aviators have the Swiss-cheese-model to visualize how small unimportant errors can stack up to a catastrophic outcome. Though in my opinion there's a flaw in this thinking as no sane cheese seller would shuffle their layers of cheese after cutting them: Hence 1-in-million chances happen all the time. https://www.aviationfile.com/swiss-cheese-model/

I'm glad I'm not the only one bothered by the implied slice shuffling in this "model". Lol! We need to think of another real world setting where a stack of randomly hole-filled sheets would be naturally shuffled.

Reminds me of https://markxu.com/strong-evidence «One time, someone asked me what my name was. I said, “Mark Xu.” Afterward, they probably believed my name was “Mark Xu.” I’m guessing they would have happily accepted a bet at 20:1 odds that my driver’s license would say “Mark Xu” on it. The prior odds that someone’s name is “Mark Xu” are generously 1:1,000,000. Posterior odds of 20:1 implies that the odds ratio of me…

24 bits seems about right for the information content of six Latin characters arranged in a pronounceable English orthography (the ‘X’ has pretty high information value though).

Earlier quoted context omitted.

Technically, it's not actually uniform, or "random" - it only has to be indistinguishable from random, e.g. if you had access to a true random source and a pseudo-random one, it should be computationally infeasible to distinguish them.

Given a finite amount of sample.values, you can always find a polynomial to match the values. You can only proclaim that something is "truly random" on epistemological grounds, assuming that true randomness is somehow exposed by the universe. This holds under quantum physics, but not under classical mechanics. Unless there is some quantum effect, RNGs based on fluid dynamics, like lava lamps, may be completely determ…

You're right that we can never find conclusive empirical evidence for something being truly random, but we can say with confidence that a PRNG is not random because we can look at the algorithm.

Punch cards? Might be a few years out of date to be readily imagined by an average member of the public.
