Speaker: N. David Mermin
Einstein's real complaint about the quantum theory was not that it required God to play dice, but that it failed to "represent a reality in time and space, free from spooky actions at a distance." I shall use the rhetorical device of a computer-simulated lecture demonstration (a cartoon version of recent experiments in Vienna) to explain both the appeal of Einstein's criticism and the remarkable act that the "reality" he insisted upon is nevertheless unattainable.

Can someone please help! With the 3 particles coming out of the source, the twio going towards B and C and passing through the stuff how can this represent the stuff left behind by A when A hasn't gone through the studf left behind, B and C have. Is it that you can think of The 3 emitted particles as equivalents and even though B and C went through the stuff left behind this is equivalent to if A had gone through the stuff left behind but it is just that the detectors B and C give a way of showing what would have happened IF the particle heading fir A had indeed gone through the stuff left behind?

Went down a rabbit hole over an afternoon or two looking at layman's explanations of QM. This is very good in showing its weirdness. The payoff is at around 58:10. You can't know both type 2 color and the type 1, either one or the other but not both. The whole thing reminds me of a board game with rules, and the rules may not make sense, but there you have it. And no one knows why its this way.

I do not see how, once the speaker started, this presentation could be boring. If it seemed boring, then you are not interested in delicate points about how quantum theory differs, by necessity, with the world as people always have thought of it. It could well be that the reasoning presented has lapses or jumps, because when it got to the crux too much was flying by for me to follow.

Is the role of physics to describe what is or what is the purpose behind it? The problem of reconciling both is that we may have to look beyond materialism as a philosophy and look at a metaphysical answer. Now that is truly what is spooky to some.

I think it would be more accurate to say that our understanding of QM is incomplete. In the lab we can entangle particles, which can mean they are combined or created together so they share properties. When you consider that the quantum objects are described as wave functions (without definite locations or momentum) it doesn't surprise me that distance doesn't matter with regards to entanglement. The wave functions are still correlated, so the measurements would be expected to be correlated.
@MatthewSuffidy

I don't really understand this totally, but I am feeling like the stuff left behind- 2 color theory, and the 3 detectors geometry has something to do with the problem here. I never really understood the Bell experiment, but thought maybe it had something to do with the statistics of the wave function vs theoretical probability.

One question...The speaker mentioned that under QM, thing _B_ (for example) could be considered the same as the "stuff left behind " thing _A_ and thus was an equivalent representation of the original "thing / stuff left behind" test...Unfortunately he neglected to explain whether or not that assertion was backed by aspects of QM currently supported by physical evidence or if it relied on the currently implied yet still theoretical only aspects...That would seem to be important as if it comes solely from theory then it's awful close to a case of using a theory to "prove" itself...Why is (for example) "thing B" (in relation to either thing A or C as mentioned in the lecture) the same as the "stuff left behind" from the first experiment?

I never thought of it in those terms but it reinforces the postulation of a holographic universe. This would explain (if you believe in such things) why thoughts travel instantaneously. Thoughts are not bound by the illusion of observation and thus transcend any perception of distance. Thanks for the insight, it was helpful.

Picture it like this... First off, you know what moire patterns formed from interference of waves are correct? What you get on a 2D plane is peaks and troughs resulting in banding and this banding is also capable of containing 3D information if the "observing" wavelength equals that of, or is some integer multiple of the original screening material which created the banding, in the case of Holograms this screen is the frequency and phase of the light which created the pattern. This process demonstrates the encoding of 3D information on a 2D plane and this same phenomenon exist on a 3D "plane" with the observing dimension being the observer AKA You... or any single particle which interacts with the 3D plane its "observing". Now with that in mind consider a 3D sphere which contains this 2D hologram on its surface in which you the observer is inside at some point. If we extrapolate this 2D wave front information into the center of the sphere it will also cause interference in such a way that if we shrink the frequency and amplitude such that it scales with the radius of the points distance from the center of the sphere what one gets is full on 4 dimensional spacetime which is theoretically capable of encoding all the information, from the start to the end of the universe on nothing more than the 2 dimensional surface of the sphere. My hypothesis above is also Testable in that due to the nature of the encoding what should result is a cyclic rhythm in the behavior of all particles such that what we really are witnessing is cycles upon cycles upon cycles. We should be capable of taking a timeline for instance and properly coiling it onto itself and seeing history line up when the proper coiling coefficients are used. Despite this needing infinite accuracy for such coils down to the Planck's scale we should be able to cheat with relative accuracy and take two highly similar events on a timeline and coil the ENTIRE timeline with coils in time equaling t*0.5. Once you see a rather nice correlation between two events, all sharing many many different vectors the proceed in coiling the coil again in harmonics of the base frequency. You will quickly see events start to line up in straight lines on the outer radius of the coil which share so many similarities it defies logic and probability unless the above hypothesis about the nature of spacetime being a projection of a 2D plane on a 4D sphere. Method 2 of testing... with this being a grander scale in which we can not influence results is that we should be capable of taking the Microwave Background Radiation we observer and projecting this data in a fashion described above and we should be able to observe rough structures which mirror the Galactic web of our universe. Finer and finer detailed maps of the MBR will allow us to result higher and higher detail. The MBR is simply just the surface of the Event horizon for the blackhole our universe is in Red shifted are it gets projected onto this higher dimensional hypersurface. OR.... This is all bullshit and I am delusional, ALWAYS and option however given the nature of wave fronts and how interference behave coupled with the fact that formulation has shown our observable universe is right in size and mass density for consideration of it being a blackhole it becomes extremely hard to ignore this all. It basically means the Big bang, the Singularity that started our universe from a single Plancks sized point is really a 2D sphere in a higher universe with all the information coming into that EH being our MBR and our Universe being the MBR of the universes inside Blackholes in our universe. Each Universe would simply be visualizing the hologram from a different angle similar to what happens if you smash a real hologram you dont get pieces of the original, you get the entire image however what it loses is the ability view it from some angles. It makes every Universe ALMOST the same... however very different as they break off at that specific time. Also, for better visualization of all this make sure you understand that at the Event horizon of a Blackhole Time and Space are flipped... This means to an observer outside the Blackhole they see matter going towards a singularity while an observer inside would see the trip towards the inside of the singularity as instead moving forward in time, not space. The inside observer would see the spheres surface as being a single point and the center singularity as being a point infinitely far in the future as time slows the close one gets to the center. For fuck sake I meant this to be a quick and simple post and my stupid ass wrote a mini thesis and even then there is so much I cant get into and this is by far surface level but I hope this makes it a bit easier to visualize the possibility we are a holographic universe as I personally believe there is no real other way as physics currently dictates this all to be true.

Since your asking for one I'll give you one but it is just my interpretation based on the material I've read -- It's not so much that these particles have some obscure means of communication faster then the speed of light as much as the space between them is an illusion of space and time which are relative. More so we are making these observations from within the space-time continuum and this reminds me of Godel's incompleteness theorem as we may never know things as they actually are

@1:13:50 Consider not classical waves, but waves with threshold-events, much like excitation waves of a collection of neurons, combined with back-propagation waves (of the opposite sign) that originate from threshold singularities to spread outward away from the singular source. Back-propagating waves smooth out the field such that future post-threshold-event incoming-waves are likely to trigger more threshold events. Thus "virtual" particles use echos to sustain itself via field resonance.

What you are saying seems to make sense. In the following article Cool horizons for entangled black holes (2013 jul) by Juan Maldacena & Leonard Susskind they suggest that ER=EPR meaning that EPR-type entanglements are actually Einstein-Rosen bridges. As I understand it, it would means that entangled particles are directly connected by a quantum-size wormhole, explaining spooky action at distance.
@BarryKort
@BarryKort 7 лет назад
In Part IV, the logical paradox is quite clear if one tries to posit some static (not time varying) internal state that deterministically governs the outcome of the "color" measurements. One can also posit some time-varying internal state machine that maps onto the epiphenomenon of the "color" measurements, provided one also assumes that all the particles advance their internal state in perfect synchrony governed by a common master clock. Mathematically, this doesn't help us get out of the logical paradox in the gedanken experiment. But what happens if the particles have their own local clocks which, while being nearly synchronized, run at slightly different rates? Then, it occurs to me that the "left behind" particles are slightly desynchronized from the third particle, so that the prediction is subtly compromised. If we are talking about polarization angles or the orientation of the spin axis in space, we now have some time-varying wobble or jitter which compromises any mathematical calculation that relies on perfect phase-locked synchrony relative to some master clock or reference clock.

I think you are partially correct. There is the element of formation of the thought, feeling or emotion, but once that packet is assembled it seems to be perceived instantaneously. It would be very difficult to prove this from an academic point of view...until mental telepathy is proven beyond a doubt. Till then it is all speculation. Good observation though.

0:35:40 I don't think in EPR's view the existence of a testing device able to test simulatneously for 1- and 2-color is sufficient to assert the reality of both properties: rather, there should be a device able to test any of the properties without physically interfering with the observed system. That's what would ensure they are elements of reality (in the EPR paper) and that's what EPR thought they'd found in entangled systems.

I think the reason for the contention is that people are thinking in terms of "particles", but the very notion of a "particle" implies that it is independent of its environment. There are no "particles" in isolation of the environment -- it's all self-sustaining resonance.

@LaureanoLuna
@LaureanoLuna 11 лет назад
If physicists read Kant, they'd understand physics is only about phenomena, not things in themselves. No physical observable is a property of things but of the way they appear to us. That's why speaking of physical properties unrelated to an experimental setup makes no sense. Phenomena emerge out of a cognitive interaction between observer and things. In measuring one entangled particle, we alter the whole experimental setup and enable the other to first exhibit the corresponding property.

I understand that. Physicists borrow from mathematicians all the time. For instance Hamilton's quaternions were ignored by physicists for years before a mathematically less powerful part of was nicked to form vector analysis, when it was needed. The converse is also true I suppose.

Physicists need philosophers (or, rather, philosophy) to know what they are talking about: whether they are talking about phenomena (i.e.the way things appear to us) or about things in themselves. This is why Bohr and Heisenberg were inspired by Kant and by Neo-positivism. This is also why Mach, Poincare and Einstein produced the theory of Relativity based on Leibniz' and Kant's conception of space.

Quantum mechanics does not require "God to play dice".

Although that could conflict with gravity traveling the spe

I agree, you could plant the scientific method within epistemology, but science is more than just its methods of inquiry.

So being able to form a coherent argument is a philosophy now? Am I doing philosophy when I explain why I'm late for work? Is that subversively epistemological?The process itself is not problematic,the jargon is.Hence why formal philosophy is worthless to scientists, and science in general. Theoreticians are largely using mathematics in their work. That their work needs to be consistent is a banal truism, which is certainly a synonym for the kind of philosophy you're describing.

The 'pet logic' of your philosopher is irrelevant to mathematics. Mathematics works just as well regardless of the position you take on its ontology. More importantly, I wasn't talking about mathematics, but physics, and science more generally. Once more, we do not need philosophers muddying the waters with jargon and linguistic formalism.

No, physicists need mathematics to know what they are talking about. Sure, a little philosophy is perhaps required, but not the formalism used by philosophers, the endless categories and 'isms' and meaningless chewing around. Einstein developed the theory of relativity based on empirical and theoretical findings from other physicists, not philosophers. You may note that it is entirely incidental that some philosophers may have been on the right track, but many more haven't. Be consistent.

This lecture needs more polishing. The facts are right, but the presentation is a bit unpolished

Yes this shit is slow, 11min and I cant stand the slow old speakers. They should have given them coaching, practice, and some caffeine.

8:00 The reason that really smart guy had an issue with Quantum theory is because its bullshit :D . I mean, seriously, God does NOT play dice... No matter how much you all want to delude yourselves into believing you have free will you are simply looking at your inadequacies for measurement and ensuring freewill exist just below that. At the end of the day that is all it boils down to, a bunch of people searching for a way to introduce some sort of control of the universe where they mathematically could not see one before. They searched, and searched, and searched, all the way down, until they got to the smallest values they could possibly measure and JUST below those values is where free will and consciousness lay. Quantum theory is just a rehash of the God of the Gaps fallacy and people have ignored glaring errors in the standard model and QED in order to keep this delusion alive. All the real geniuses from back in the day knew and admitted renormalization was absolute absurdity and yet without it our entire house of cards collapses faster than a modern day Chinese sky scrapper.

Philosophers have nothing to say on the state or interpretation of our knowledge from physics. Sorry.

I feel that the physical theory itself is much more simple and much more clear than his simplifications where he uses the stuff taken from his behind! LOL
