Causal loops in quantum theory is a subject pretty close to my heart. That said, I would approach it bottom-up, rather from this cosmological standpoi...
I've read this a few times now and I'm still not sure I grasp the thesis. That is, I'm not sure which you think are the key points. The most peculiar ...
Is this a wind-up? I have never had so many notifications on a thread I have no interest in. And please don't give me lessons on manners. I answered o...
A neuroscientist can scan your brain and determine what decision you'll reach before you reach it, for some test scenarios. There's a good reason for ...
Yes, the net is being cast very broadly in what constitutes randomness. Our ignorance, the complexity of the system, and the sensitivity of its laws t...
That's right, which is why I cited the measurement problem as a potential disproof of determinism. Unfortunately we don't have a testable theory of me...
Does this resolve beyond the cogito? I can doubt whether I exist, which implies the existence of a subject (self) and an object (self) because they ar...
I understand why you're evading the question, but even you must see this is horrifically inconsistent. On the one hand, things seem deterministic but,...
Okay, so irrespective of the actual physics, if we use stochastic methods to model them, they're random. So when I said: you really were insisting tha...
No, I understand that, that is, as you say, very simple. Simplistic, even. You said the above paper 'looks like a duck', i.e. "displays a behaviour re...
So, let me get this straight... You are aware that stochastic methods are employed to model both random and intractable, statistical systems. And you'...
As you will, but if you are aware that stochastic methods are used to model deterministic processes and yet insist that anything modelled stochastical...
Indeed. Point being you can't read 'stochastic' and infer 'non-deterministic'. For instance, Brownian motion is modelled stochastically. That is not t...
Yes, that is the measurement problem. At a given time, we know how much of the wavefunction should be |decayed> and how much |undecayed> but we don't ...
No, it's not. Being able to approximate the laws of the universe well is dependent on the universe -- or at least the part of it being modelled -- beh...
So, yes, radioactive decay is an example of a quantum field theory, the electroweak theory. But it isn't characterised by atoms or hadrons either spit...
Yes. The Universe appears to behave deterministically... We can write down formulae to predict outcomes and find them reliable: x in, y out. (With or ...
Yeah, I think it's pretty mundane stuff. Certain quantum phenomena like tunnelling and the exclusion principle have small effects on simple chemicals ...
I think we're speaking at cross purposes; possibly I misunderstood your earlier point. Reading back, what I think you were referring to was random flu...
Determinism is not dependent on being able to rewind the universe. As I said, you don't know my position. It would probably surprise you. It's not a m...
There's been a recent paper in which quantum entanglement between two large (i.e. compared with atoms) objects were entangled over a distance, but yes...
And yet when you rewind a VHS and play it again, you do expect exactly the same movie, not a random one. ??? That's real. Magically rewinding the univ...
Yes, this is indeterminism-of-the-gaps. As our technology improves, error reduces, and this alleged non-determinism of nature is obliged to retreat. I...
If this were true, science wouldn't work, technology wouldn't work. One has to be able to know a sufficient amount of information in order to guarante...
Okay cool. Sorry, it's come across several times like you're willfully misunderstanding everything. Obviously there's a slight language barrier and I ...
What I mean is that as we measure, say, the spin of a neutron to ever greater precision, the degree of freedom of non-determinism to show its face get...
There are no random fluctuations in the wavefunction. In even the probabilistic interpretations of QM the wavefunction evolves deterministically under...
Again, not relevant. Newton's laws are sufficient to wang a probe around the solar system for a few decades and land it in your back garden. Tackling ...
If the relevant information required omniscience, it would not be a good test for determinism. Gimme a holler when you acquire the ability to retain i...
And, as I keep saying, you don't to devise a particular experiment. Any experiment that fulfils those criteria would suffice. The important thing woul...
Can you explain this in more detail? Why would a non-deterministic world appear like ours? Why would a non-deterministic world "appear" at all? You po...
I'm not convinced you've understood me at all. The phrasing for knowability I gave above was "all relevant information". For an experiment that is ins...
UBI is also backed by the Glib Dems. I think that's going to be a mainstay of the progressive platform in the near future; 51% of voters support it. T...
Agreed, but it's important to be aware of why, and not lump unknowns, intractability, and genuine non-determinism into one catch-all. Otherwise you ge...
It only has to be known to the requisite precision of the experiment. In the Galton box, this would be extremely high, but not necessarily perfect. In...
Yes, lots of experiments have relied on initial states prepared to high precision. Yes, and that is a great example of unknowability in a chaotic syst...
Actually, we haven't touched on my beliefs yet which are a little more exotic. I'm merely criticising your belief atm. It only takes one observation w...
