Die rolling for any practical purpose is completely random.
Sure, no problem.
Maybe not "completely", but your point is not lost.
You can't have every piece of info except in theory. Practically..nope.
Pretty much, but not exactly.
For example, you could just drop the die straight down from a height of 1 mm and the only force on it would be gravity.
If the 6 was face up when you dropped it, then the 6 would still be face up when it landed on the table, and you could predict the result every time.
You'd complain that the roll wasn't fair, and you'd be right, but that's only because we didn't introduce enough forces to make the result
look random.
Since it was so easy to predict the result, wouldn't you say that it was not random?
What if I slid it across the table so that there was also a lateral force, but not enough to make it roll off of the six-side facing up? Wouldn't you say that it was still not random?
Why, then, if I add an additional force that makes us unable to predict the result, do you all of the sudden start calling it random?
If you insist that every roll must be random, then you must also admit that when I drop it from 1 mm that it is random as well. But you won't be able to say that.
What you are calling complete randomness, is actually only a complications of the number of forces that makes us unable to predict the result.
But if we did know those forces, then we could predict it. So how can it really be random? Isn't it just the appearance of randomness?
I agree that for all intents and purposes, we're totally fine with calling it random.
I'm just pointing out that it actually isn't.
So I see no value in taking a common sense random event like die rolling.... dissecting to a microscopic level and determine if you had every piece of information before hand. You could predict it.
The only reason I'm insisting on the point is because of the way you were ridiculing the idea.
You were acting as if it was so hilarious that someone would even make the claim that there's nothing to do but laugh at it. But in actuality, the claim turns out to be true and you're left with egg on your face.
So sure, a die roll is random.
But its not really random from the point of view of the laws of physics. Every roll is just the result of a bunch of forces acting on the die in a completely predictable manner.
