    The standard theory of quantum mechanics leaves a bit to be desired. As Richard Feynman put it, "I think I can safely say that no one understands quantum mechanics." This is because observations of experiments have led us to a theory that contradicts common sense. The wave function contains all the information that is knowable about a particle, yet it can only be used to calculate probabilities of where a particle will likely turn up. It can't give us an actual account of where the particle went or where it will be at some later time.

    Some have suggested that this theory is incomplete. Maybe something is going on beneath the radar of standard quantum theory and somehow producing the appearance of randomness and uncertainty without actually being random or uncertain. Theories of this sort are called hidden variable theories because they propose entities that aren't observable. One such theory is pilot wave theory, first proposed by de Broglie, but later developed by Bohm. The idea here is that a particle oscillates, creating a wave. It then interacts with the wave and this complex interaction determines its motion.

    Experiments using silicone oil droplets on a vibrating bath provide a remarkable physical realization of pilot wave theories. They give us a physical picture of what the quantum world might look like if this is what's going on - and this theory is still deterministic. The particle is never in two places at once and there is no randomness.

    The idea of pilot waves takes me to our common dream-state we all experience. What we can't work-out with logic during the day is often answered on waking in the morning having gone to bed thinking of the problem. In a sense... the particle 'me' disappears as I enter sleep and the wave 'me' emerges to find the answer. In a fractal sense... I believe the two operating systems or patterns are consistent.

    The results of Pilot Wave Theory are just too good, it seems to me that a good part of this theory must surely be ALONG THE RIGHT LINES of what is really going on at quantum level.

    I feel there are big clues to the quantum truth here. It'a all just too coincidental otherwise.

    Imagine a one dimensional being trying to comprehend a two dimensional reality.
    Now imagine a two dimensional man trying to comprehend a three dimensional reality.
    Now imagine a three dimensional man trying to comprehend a four dimensional reality.

    The tiny three dimensional man will perceive his existence in time, as being nothing but the present real-time.
    Although, he will be aware that he is moving through time, throughout his life.

    Meanwhile, the four dimensional reality exists. It is composed of four dimensions. Three dimensions of space, and one dimension of time. However, to our tiny three dimensional man, to him he lives always in the present time, and so he doesn't perceive the four dimensional structure of space-time for what it truly is.

    There are two sides to reality. One is the inside, also known as the present time or real-time. The other side, is the outside, otherwise known as all time of that 4 dimensional space-time structure, other than the inside, or present/real-time.

    On the outside, events are 4 dimensional. They extend across both space and across time.
    On the inside, events occur at a single point in space at a single point in time.

    If you would then include both laws of physics, meaning those on the outside, and those on the inside, everything seen, concerning things like particle/wave duality, action at a distance, delayed quantum choice, quantum erasure, etc.,
    is seen exactly as you expect it to be seen.

    Exclude the laws of physics present on the outside, as do today's physicists, and the bizarreness and incompleteness of quantum mechanics is born and maintained.

    i'm much more comfortable with the pilot-wave theory. However, i'm still unable to confront the duality in my head regarding redshift/blueshift from EM waves. The interference patern could be explained by interference from EM waves, and the same EM waves explains redshift (blueshift) when senders of EM-waves leave (approach).
    However with the splitting of the particle and the wave, i don't understand how that would go (neither do i arrive at any intuitive conclusions with the copenhagen, many- or zero-world explanation, since they all keep the light as a photon).

    I was walking along the beach that had two posts sticking out of the water. On the shore of a beach I saw the same wave patterns that we see in the double slit experiment. This is the opposite yet get the same results of your typical slit experiment has, they are double Post. Really is eventually comes down to the question of is the ocean made out of particles of water or waves of water? Obviously they are both in the interaction of both. This is why quite some theories and mechanics do not make sense they cannot observe the obvious.

    In the droplet case, the wave is made by physical matter unlike the wave like behavior of a particle which acts as the both a particle and a wave simultaneously.... so can we suggest that there is some kind of an invisible physical fabric on which waves can form with the influence of particles? And maybe disturbing our measurements?

Math is no going to explained us what is hidden in quatum physics. Math is useful to discribe if we have the right interpretation about something but to have the right interpretation we havet o be more open about new ideas and more imagination beyond academic boarders....

    Intriguing. It may indeed appeal to those who want to hold on to their belief in determinism, but if reality is deterministic, then no theory about anything would have any value, since the theories themselves would be determined. Also, still unexplained is consciousness, of which we each have proof, and what is consciousness without at least some level of freedom of thought, i.e. free will.

    • mike4ty4
      mike4ty4 12 дней назад

      I don't get how any theories would have "no value" if they are themselves "determined". Value is something we construct in our minds, and our minds would work the same way whether their operation was determined in advance or is created on the fly. So we'd still get sensations of "value" and so forth, and furthermore "free will" can be a _feeling_ . (One thing I've often argued is that to me the whole "free will" debates are moot because two things: for one, we cannot know all the factors that would go into a decision outcome and furthermore all the different brain processing patterns to produce a useful prediction a long time in advance, and for another, whether we have free will or not, would we really _feel_ a difference? If no free will, we certainly sure _feel_ like we have some. If the same set of brainpatterns was produced by an actual free will or produced off a tape, in both cases generating the same set of subjective experiences, would we really _feel_ any difference? That is, would we _feel_ like, if we had no free will, we were being "out of control" like a tape player? What if though what's also on that tape though is a feeling of control? So whether it exists or not, we know for _sure_ the _feeling_ exists and _that_ is what we have and use to inform our actions, and I'd suggest we'd have that whether it exists or not and thus it is of no real relevance whether it exists or not to our living.) Also, a theory has value if it's useful. We could still "make use" of those theories even if our making-use, and discovery/invention of the theories was all scribed out long in advance.

      Also if there is no free will I'd think the Bohmian approach is a rather interesting way to have it, because in a _sense_ you could say it _does_ have free will: the Bohmian waves are nonlocal and acausal, that is, interactions, or, well, the classical movement of the particle, depends on things going on arbitrarily far across the universe and perhaps also in past and future due to relativity theory (which would break down the usual ordering of causality because of the faster-than-light transit). With the universe most likely being infinite, according to our best observations, that means it contains an infinite amount of matter and so an infinite number of possible influencing factors. Is there a practical difference between determinism that depends on a literally, actual, completed infinity of information, and nondeterminism? I would wager there is not, because we can literally never, ever manage to grab all the information, from across both space and time. Thus "free will" is restored in a sense, yet at the same time does not exist either, because it _is_ deterministic, and then on the final hand it becomes essentially "an expression of the 'will of the Universe'" because as said all of the Universe comes to affect that motion.

      The bit of beef I have though with the Bohmian theories is their mathematical elegance, or not. Having a separate and simultaneous "classical" and "quantum" existence for each particle (one as the classic particle moving on trajectory, the other as the quantum wave function) provides as a nice way to do away with the whole debate around the classical/quantum boundary - there is none! Everything is simultaneously _both_ classical _and_ quantum, and it's just a matter of which one has more "clout" in a given situation. E.g. in a quantum computer, or so I've heard, all the action takes place in the quantum wave function, while the particle's motion carries very little computational meaning. Yet in a classical computer, of course, it would be that the classical motion would be very much significant, and the quantum component carries little meaning. This is a very neat and nifty way to unify the two types of computation (and intringuingly, and tantalizingly, hints at the possibility of some form of "borderland computation" where both parts are playing a role - although I'm not sure that would work out.).

      But when I say about lack of mathematical elegance what I mean is for the classical state the Bohmian theories privilege the position, and likewise for the wavefunction, it is the position wave function. An often-underappreciated aspect of regular quantum mechanics that goes unmentioned in many of these presentations is that regular quantum mechanics doesn't just talk about a wave function that's a "wave in space" - but in fact you can also take the same wave function and transform it to a physically equivalent, but much more abstract in concept, "wave in momentum space"(!). That is, there is a psi function psi(x, y, z) that forms a wave-pattern in positional, physical (x, y, z) situating space, _and_ there is an _exactly related_ chi-function chi(p_x, p_y, p_z) (to distinguish from psi) that forms a wave-pattern in _momentum space_ (p_x, p_y, p_z) where coordinates represent a possible _momentum_ for the particle! (And has the same interpretation with |chi|^2 being a probability density only now for probability of measuring a momentum!) And neither of these are privileged: both are _different 'basis'_ representations (as in Linear Algebra, if you've done it) of a common state vector in a Hilbert space vector space. Yet Bohm chooses to, imo, rather arbitrarily, privilege one of these over the other, and then devise some other, more sophisticated explanations, for how the others appear as the result of measuring devices designed to detect them. I find this though a bit unappealing - though that doesn't necessarily mean BM would be wrong (nor does it mean it's right) of course, although we have no way to distinguish _any_ interpretations of QM right now. The Hilbert space is a neat thing - as is linear algebra in general. I've tried a bit to toy around to see if perhaps there's a BM-like theory in which the "classic" part of the particle is not just a position triplet but some sort of more sophisticated mathematical thingy that, when you look at it in different ways it gives you a definitive position, _and_ momentum, _and_ ... like the Hilbert space does for the wave functions (and ideally the two would have to be related) but with no luck so far. Perhaps though someone more expert than I am in this right now has already done it. I'd be interested to see the results of that work, if it exists. If anyone has any suggestions, I'd like to hear about them.

    so interesting........very cool effect.....but the underlying brain collisions between classical and quantum theories involve trying to apply classical tools and thinking to quantum situations. this is just another bridge to span the classical-quantum gap. Even the Bell theorem is just another name for unknown ie ..hidden variable theories? wow!... copenhagen is the best explanation of the wave/particle dualism....so far. observation does change outcome as you are interfering with the system!.... I learned about Quantum mechanics in the 60's, in Pchem...you wrote the wavefunction and calculated ....i really didnt get it then....and I still dont get it completely...

    Why is it hard to come up with experiments to identify which theory is going to be a closer representation of reality?

    • mike4ty4
      mike4ty4 12 дней назад

      For one, BM was _designed_ to give the same predictions as standard QM. That makes it somewhat difficult to test. However, some have suggested it might not be.

      One of the interesting things I've been thinking about regarding BM is how BM reacts when it is placed in line with special relativity. Because BM involves actual faster-than-light transmission (and not just faster-than-light correlation, which is different), it violates causality. Some say this is a reason to hate it, but for me I prefer to try the iconoclasm approach, smash causality, and take this seriously. What I'd in particular wonder about is if any of these faster-than-light interactions could ever end up with a "grandfather paradox", and if so, how does the theory, when transplanted to the Minkovski spacetime, react to this kind of situation? Does such a reaction cause it to generate nonsense, or does some sort of "self consistency" principle naturally arise? Furthermore, if one does, _does this in some way affect the predictions for experiments, probabilities, etc._ ? E.g. does it lead to a violation of the Born rule or something? This could make/break BM if it suggested some sort of unusual effect due to reversed causality. It might take some rather extreme experimental methods though, like putting particles on spaceships moving near the speed of light. Then again, maybe it just all "gets averaged out" still and thus ends up with nothing. Nonetheless, the thing is I have not heard it often discussed, or even discussed at all, rather what comes up is more that "if it breaks causality, that means it's bad theory" instead of actually trying to _push that option through to the end_ to see where it leads.

    This explanation is very logically strong. Electron is interfering not with himself, but with space where it flies. Also, it is not superpositioned in field of probabilities, but vibrates so fast, that our timing sensors cant detect it in expected position every time when it passes by. Besides it explains that when mass increases, wave effect decreases and completely disappears at some point. (very good visualised by those big droplets that are not bouncing). But, what about observer paradox? How could it affect the pilot waves, so the particles starts to move straight?

    • mike4ty4
      mike4ty4 12 дней назад

      Well it doesn't necessarily "vibrate fast", it simply moves along a path that is determined by the evolution of the wave function. The wave function is what does all the interference and other "quantum" stuff, the electron just ends up wherever, but when you have many electrons, all coming from different, effectively random places (due essentially to randomness in the experiment due in turn to the holistic interaction of the entire cosmos), these waves guide them so that, when measured, you get the expected probabilities.

    It seem that in all "sciences" an orthodoxy develops and new or different ideas are rejected not by reason but rationalizations. The desire to reject determinism at all cost is not rational. I understand a deterministic world is not as much fun as a random one but think of all the new discoveries we can make if we seek the truth no matter how painful and upsetting that might be.

    • mike4ty4
      mike4ty4 12 дней назад

      The rub is it's not just a deterministic world, it's a deterministic world that is effectively nondeterministic by action of universal holism: all the "deterministic" _micro_ -scale phenomena are determined by literally _everything else going on in the universe_ - at _past present and future_ due to causality violation thanks to Special Relativity which mixes past, present, and future. Since the universe is almost surely infinite in both space and time that makes it mean you'd need to have an infinite amount of information from literally all of space _and all of time_ to figure out exactly what any given particle was doing. So it's determinist but _also_ in a sense, nondeterministic. Queer logic not classical logic :) It both is and isn't at the same time.

      Bell's Inequality only says anything at all when taken in conjunction with the Einstein-Podolski-Rosen thought experiment.

      Together, they disprove the idea of that any *Local* Theory of Quantum Mechanics can ever give an accurate explanation of it's phenomena. To be more specific, EPR proves that no Local Theory can work *without* Hidden Variables, while Bell proved that Local Theories can't explain all the experiments *with* Hidden Variables either.
      They say absolutely *nothing* about whether Hidden Variables themselves should be disqualified -- well, except that EPR strengthened the case for Hidden Variables, and then Bell brought the case for them back to the original _"We don't know at this point."_

    Alright people, calm down. Keep in mind this is only appealing because we can see it. Most physicists don't think this is the correct interpretation for a variety of legitimate reasons.

    IMO, what reality is, might be unknowable. What we attempt is not to unravel the mystery of ultimate reality, but rather to develop models that predict observable behavior. In that light, both of the two interpretations are acceptable to the extent that they are useful (which is also true of Newtonian mechanics).

    The question of what is actually "real" can be left for another day, if indeed that question is even meaningful.

    After years of knowing of the results of the double-slit experiment, I finally have a basic understanding of a explanation. While it as true that this is not a completely accurate description, it does make sense. Thanks for the work.

    The pilot wave theory could explain why the particle moves in a random direction but it doesn't explain why particles don't produce an interference pattern when being observed.

    This is a much more intuitive explanation of Young's experiment. I have long felt that the original ideas of an aether or fabric of the universe that we just have not been able to detect is probably correct. This would go a long way towards explaining many other things, including gravitational waves, mass-less particles et al.

    So does the idea of the electron behaving differently depending of whether it is being observed or not still hold true, or is that just not true?

  • Kristy Hamlin

    Okay but can pilot wave theory explain delayed choice double slit or the "quantum eraser" experiment which demonstrated that even when which slit an electron went through was detected after the position measurement of it's entangled partner, an interference pattern was not observed, whereas when this information was afterward lost by not hitting a detector, an interference pattern was observed? It seems to me that unless pilot wave theory can explain these observer experiments, we are still forced to accept Copenhagen for the time being.

    what would happen if you put detectors (that use or absorb the waves to know where the droplet passed)behind the slits??
    would the droblets behave like particles and end up in just two spots??

    I prefer the pilot wave explanation, the copenhagen interpretation looks too much like "we can't see, therefore it [the pilot wave] doesn't exist" to me. the pilot wave sounds a lot more plausible to me.

    there's one thing I missed in the video. the pilot wave for the bouncing oil droplet is the oscillating water surface. what would be the water surface of the free electron, for example? is there even an educated guess on the matter?

    If the pilot wave is true, why does the wave disappear when you take a measurement?
    It sort of makes more sense as a property of the particle itself right?

    This droplet (as the particle) riding the space-time fabric would explain how you can create electricity with magnetism, you bascally pull out the electron as you are doing now using a toothpick.
    And also why particles behave like waves.
    This would also explain heavy (or bigger) "particles" causing a bigger disturbance in the space-time fabric explaining gravity.

    Love this video, because it is a sensible explanation.
    When people don't know something there'll be always one explanation: 'It's some mystical supernatural thing which is random or controlled by a higher intelligence.' It is a stupid explanation which you could use to explain anything always. Obviously something like shown in the video is a far more logical explanation.
    Scientists today are really silly. They say that they basically don't know what form or shape a photon is. Then they do experiments as if they know and explain the answers as if they know. It's like saying the speed of light is the maximum speed. This is claimed because they thought photons have no mass, thus no rest mass, thus when emitted it must travel at the maximum possible speed. Then when something travels faster they claim it must be bending 'spacetime'. Like really? And they still believe this although it's proven photons actually have mass?
    Science at this point is less logical than many religions. Religions are very logical actually, except for the claim there is an almighty being. Science would be as logic only if it claimed that we live in a simulation, then all these stupid claims can be justified. Yet, there is no reason to say it's magic apart from assumptions which are silly.

    I never bought Copenhagen and neither did Einstein, although he dismissed pilot wave as well. The electron is there, just because we can't measure it doesn't mean it didn't have a location before we measured it. I'm pilot wave all the way. Like Einstein was at least rumored to have said, was the moon not there until I looked at it?

    So, with very simple words, let me see if I got it:
    -The wave expands in all directions and dictates the movement of the particle
    -The particle moves in one direction at a time, and that movement is dictated by its interaction with the very wave it creates;
    So, we say that in quantum mechanics "a particle can be in 2 places at once" because we measure those places based on the wave? Because the wave is in those 2 places and therefore can guide the particle to either of them?
    And now we reach the conclusion that the particle is never in more than one place at a time, rather that it has the possibility of being in either of those places as long as its wave covers that area;
    I have been digging into this subject for an absurdly SHORT time, so correct, elaborate and enlighten me about the physics in this please :D

    I'm a big fan of the hidden variables theory (out of which the wavefunctions in QM are built up). What I like so much is that there is a mechanism that mimics the probability interpretation. How can an event based on irreducible chance take place? How does a particle "know" when it's going to decay, for example? You can, of course, say that the irreducible chances determine when a particle decays, but what does that mean? How does a particle "feel" when it's going to decay? Chance is a human made concept, involving our lack of knowledge, which is then applied to, say a dice, and in this picture if you roll a perfect dice, the chances are one sixth of each number on the dice in the limit of an infinite amount of rolls of the dice. Now how can you objectivize this human concept and apply it to the interpretation of QM, while hidden variables are much more objective and offer a neat explanation of the so-called inherently, irreducible chance interpretation of the Copenhagen interpretation? For the Brown-particle in a fluid, the movements are not inherently chance based. There is even an uncertainty relation developed for the Brown-particle. But we know that the erratic behavior of the Brown-particle is caused by the actions of enormous amounts of the molecules in the fluid, which can be compared to hidden variables.
