Are you arguing that thrown dice are not 'random' and QM is 'random'?
Yes, that is precisely my position.
Dice can be describe via classical mechanics to the extent required to predict their results.
Quantum mechanics, on the other hand is *inherently* random.
Is your reasoning that we have developed sufficient tools of prediction for dice and we haven't developed sufficient tools of prediction for particles? In other words, the 'randomness' of it is dependent upon the sophistication of our technology? In other words, once upon a time we didn't have sufficient tools to predict the outcome of the dice throw, but because of our technological development dice throws have, all of a sudden, ceased to be 'random'?
No, it is dependent on the fact that dice are macroscopic objects where the quantum randomness doesn't significantly affect the end results.
We need to talk about what random means, because I don't think you are understanding what I've said about dice and QM.
OK, what does randomness mean to you? I've stated that, for me, randomness means that it is impossible to predict what will happen *even in theory*. Chaos, as opposed to randomness, can happen in deterministic systems and amounts to sensitive dependence on initial conditions making it *difficult* to predict results, but not impossible in theory.
I don't agree or disagree with this, but I want to know what this has to do with randomness. Bell's inequalities came up because you were trying to make a statement about the fundamental nature of particles. I don't think you are saying anything new here and my responses would be a repetition of what I've already said. There is sufficient disagreement about what is meant by (how to interpret) Quantum Mechanics that I'm not sure we are going to come to a productive end if we argue about what Quantum Mechanics means.
I find most attempts to determine what QM 'means' to be an attempt to force QM into a classical model. That, to me, is backwards: we explain why the old model works based on the new one, NOT the details of the new one based on the old model. QM has supplanted classical mechanics and classical notions of causality. Trying to force classical notions into it is doomed to fail.
So perhaps we should focus on whether or not we can come to a sufficient agreement about the meaning of 'random' and leave off, for now, the question of whether or not Quantum Mechanics is 'random'. What would be required for us to declare that something is 'random'.
I gave my working definition above.
Do I understand you correctly: before we understood that the speed of light was constant in all mediums, the speed of light was 'random'? This is because the theory did not predict the speed of light.
No. The speed of light *wasn't* unpredictable *even in theory*. Given sufficient data, the speed could be resolved.
You seem willing to assert that 'gravity' is 'not the result of a method or conscious decision'. Is there an experiment that confirms this hypothesis?
Huh? is there *any* evidence to even suggest an intelligence is involved? No. Instead, we have definite dynamical laws (physical laws) that we can use to predict future events.
You also say that 'gravity' is 'not random'. To what precisely are you referring?
F = G*m1*m2/r^2 is an equation we use for prediction. Are you referring to the "Law of Gravity" as an immaterial thing in our imaginations that we use as a tool for prediction? Or are you referring to the action of objects subjected to a Force of Gravity where the masses and radii of influences may or may not be known and therefore the resultant force on an object may not be precisely known?
Our ability to measure doesn't affect the ability *in theory* to make specific predictions for gravity. And, in practice, we can and do make such predictions with high quality results. That means the action of gravity is not random. The orbits of the planets are not random.
This is distinctly different than what happens in QM, where *even in theory*, the results of an observation of a superpositional state cannot be predicted, even if we have perfect information about that state beforehand (i.e, what states it is the superposition of and with what weights).
So, for example, we know the approximate mass of the Earth (we don't know the precise mass of the Earth). This allows us to predict the acceleration due to the Earth's force of gravity, within a specified area around the world, to within a certain
margin of error, but we remain unable to
predict with absolute certainty the precise acceleration of an object at any point and time due to all of the collective forces upon it, in spite of having an equation for universal gravitation. And experimental data confirms that the acceleration due to gravity at any particular point on Earth varies slightly over time.
I think 'random' refers to things that
we don't predict in practice or don't make a conscious effort to control. Every science experiment has potential influences that introduce error. The influences that cause variations in measurement are 'random', are they not? What word would you use to describe the cause of these errors?[/QUOTE]
