[...]My point was that we had dices and coins even before the
20th century. There are classical sources of randomness such
as the bean machine (Galton box) or the roulette wheel, that
one really cannot predict and which deliver a certain
distribution of frequencies.
Dices and coins usually are random enough to be deemed
sources of randomness. I will call them Â»classical sourcesÂ«
However, today we also have quantum sources of randomness,
and we know that they have different properties than
Are you saying that, given two streams of "randomish" numbers,
one from a roulette wheel and one from some quantum source, it's
possible to tell which is which just by examining the numbers?
Is that correct? If so, I find it surprising. Can you summarize the
difference in a way that a non-statistician is likely to understand?
