That's not quite true. Under super-determinism (which just means determinism+entanglement), you will observe reality exactly as quantum mechanics pred...

Did not mean to cause any discomfort, but we know the non-computable numbers and the non-computable functions exist because they are indispensable in ...

Here's a rather striking example of the literally trillions of possible examples that could be chosen: http://www.nature.com/news/two-hundred-terabyte...

Yes, and not only can a Turing machine be instantiated in Reality, but that Turing machine can instantiate another Turing machine abstractly. But then...

Maybe you should read the OP.
January 14, 2017 at 11:22
If you run the physical causal law in reverse, does B ? C ? A make any sense?
January 14, 2017 at 10:38
You mean like the electrical signals in your brain, mechanically influencing your fingers?
January 13, 2017 at 17:04
Still, it is tempting to think that, when a team of mathematicians have finished programming a computer to perform a proof, and finally, after months ...
January 13, 2017 at 16:52
Would it surprise you to learn that classical mechanics can also be formulated in terms of wavefunctions on Hilbert space? No one thinks there are pro...
January 12, 2017 at 16:13
The Copenhagen is anti-realist; it is a purely epistemic theory. The "Standard" interpretation, taught at most (American) universities calls itself Co...
January 12, 2017 at 10:59
The wavefunction is NOT a probability wave! It's not even a probability amplitude wave! According to Copenhagen, it does not exist. According to Binne...

If I thought I'd "invented theories and what have you", I'd probably want to try out my ideas in a forum before inflicting them on busy professionals....
January 11, 2017 at 12:48
That is not historically accurate, and you really need to stop pretending quantum mechanics is a "model", it's not, it's a theory i.e. a statement abo...
January 11, 2017 at 12:40
So, the laws of physics operate the "unique set of information" and not on the actual physical system? But what does the operator operate on? None if ...

Sure, if there was no such thing as the measurement problem, there would be no need to solve it.
January 10, 2017 at 21:58
But that does not seem to be what Professor Binney is saying. He is claiming that the uncertainty principle is epistemic due to the large number of st...

I'd ask him to explain the Elitzur-Vaidman bomb tester - a device that can identify whether a photon-detecting trigger attached to a bomb is operation...
January 10, 2017 at 16:46
So, you've got "direct" evidence for the Higgs boson or gravitational waves? How about direct evidence for particles turning into waves when no one is...
January 10, 2017 at 16:35
Now it seems as if he is defending Copenhagen.
January 10, 2017 at 16:18
Hidden variable theories are ruled out. I have absolutely no idea why people still cling to them. Well actually I do - they wand quantum mechanics to ...
January 10, 2017 at 16:11
Just to cover the most important point first, so it can be ignored immediately: Copenhagen Interpretation does not even begin to explain reality, so s...
January 10, 2017 at 09:07
It's not metaphysical in the slightest, it's the real physical situation. And, the other worlds are required to explain what we see in this world in t...
January 09, 2017 at 09:20
That's not a postulate of Everettian QM, it's an inevitable consequence.
January 09, 2017 at 00:33
There are bigger costs than non-locality. The theory doesn't work. It can't be made relativistically invariant, requires absolute time, and is restric...
January 09, 2017 at 00:30
You presume too much. Gravitons are a nice idea, but there is zero evidence for them. As far as we can tell, physics takes place in a space-time.
January 08, 2017 at 20:06
Absolutely! My view is that Copenhagen Interpretation should be discounted as a scientific theory because it is non-explanatory. But then I adhere to ...
January 08, 2017 at 17:57
So mathematics is a by-product of laws of physics which permit the representation of one physical system by another - i.e. laws that permit abstractio...
January 08, 2017 at 14:51
It doesn't matter what determines a measurement. All that matters is that you can predict probabilities associated with whatever you decide to measure...
January 08, 2017 at 11:20
Isn't Angela Merkel one of those?
January 08, 2017 at 01:03
It is undoubtedly counter-intuitive, particularly as there is a great deal of work that indicates that for a classical Turing machine, operating under...
January 08, 2017 at 00:58
We've got a pretty good idea of what it is like to fall into a black hole, so I don't see why you could not in principle do this - any finite system c...
January 07, 2017 at 12:02
The visible universe could hold ~10124 bits of information if it were a black hole of the same size. I've seen arguments that the the number will be o...
January 07, 2017 at 11:20
Simple question: How many bits of information are required to fully describe the visible universe? How many states are available to a quantum computer...
January 05, 2017 at 23:30
It depends on the size of the black hole. If the black hole is smaller than the visible universe, then yes. More interestingly, a universal computer i...
January 05, 2017 at 22:19
False physics. OK, perhaps that's a bit of an overstatement. There exists a very strange interpretation of quantum mechanics, that is compatible with ...
January 05, 2017 at 17:47
Despite being surrounded by abstractions instantiated in all sorts of physical systems, from DNA to computers, you simply deny this and assert that th...
January 05, 2017 at 17:45
Your link doesn't work. However, whatever you think determinism implies or otherwise, what can and cannot happen in the universe is solely determined ...
January 05, 2017 at 17:01
Such a prediction is impossible for false physics under an out-dated conception of computing.
January 05, 2017 at 12:48
Surprisingly, according to the laws of physics, simulating the entire visible universe is indeed possible using a universal computer, from within the ...
January 05, 2017 at 12:45
If abstractions were purely mental (whatever you might mean by that) then they could not be instantiated in physical reality by physical objects like ...
January 04, 2017 at 21:35
So, Information Theory is a complete waste of time, rather than an explicitly counterfactual theory of a type of abstraction, underlying much of techn...
January 04, 2017 at 16:58
But there exist necessary truths about the set of primes. Some of these truths have been set out in proofs. So what is going on if the subject of thes...
January 04, 2017 at 15:38
What is mathematical proof for then? Given that there are thousands of books and papers on properties of the primes, which have been discovered, you m...
January 04, 2017 at 15:10
Start wherever you want. But remember, we need a set of observations from which to induce the theory an an unexpected observation if you want to abduc...
January 04, 2017 at 14:39
Why don't you propose a principle of "Predictable Regularity", then we can use it to describe the universe from the big-bang to the heat-death, with a...
January 04, 2017 at 14:36
Under real deterministic natural law, counter-factuals can be regarded as meaningless. In the block-universe of general relativity, there is no room f...
January 04, 2017 at 14:31
Quantum entanglement provides a straight-forward example. What series of observations resulted in the induction of the theory? What was the "surprisin...
January 03, 2017 at 22:08
So successful that you can't give a single example of a scientific theory arrived at by that method.
January 03, 2017 at 16:44
In general the future does not resemble the past, and it is the role of science to explain the regularities and irregularities. There is no such princ...
