My point was just to see if you were arguing from a well-thought-out personal worldview, or just parroting a party line (or template). For example, for all practical purposes (e.g. science & technology) I could be placed under the heading of "Materialist". But, for theoretical purposes (e.g. philosophy & ethics) I might fit better into the category of "Idealist". That's because the non-human material aspects of the world have no Ideas (words, concepts) for us to argue about : either it is, or it ain't.And that seems to me pretty clear in itself - is there something about it you did not understand that I could clarify? Why would you need a superfluous label, or template, to consider it? Or more simply, what's your point? — tim wood
Are you using Wittgenstein as an authority to justify an evasive non-position on a philosophical question? Does that side-step imply that you have no philosophical worldview, or just that you don't want to expose your subjective personal "template" to objective critical analysis? I too, am wary of being dismissively labeled, but it's a risk I'm willing to take, in the interest of refining my beliefs in the give & take of philosophy. Perhaps you would be willing to deny the labels that don't apply to you?Would you characterize the world model described above as "Materialism", or "Physicalism", or merely "Atheism"? No information, no patterns, no interrelationships, just atoms whirling in the void? — Gnomon
I wouldn't characterize it. I have a memory of something read that I think came from Wittgenstein, that all theories are templates placed over the world, and not to be mistaken for the world itself or how it works. And buying that, I have no urge to resort to templates - except of course when my human business requires me to. — tim wood
One interpretation of "politics" is "polarized people" : Lords vs Commons, Republican vs Democrat, us vs them ; friends vs enemies ; Good vs Evil ; our people (NAZI volk) vs aliens (Jews, etc). That rational (non-emotional) assessment sums up why I am literally apolitical. It's not that I have no interest in the issues being argued, but simply that I'm not prepared to choose-up sides and fight for my values. My personal values are multivalent, and are found on both sides of most either/or, two-value party lines.I’ve recently discovered this term “apolitical” and since political opinions are tied to values most of the time, I was wondering what an “apolitical” person without values would be like. It's obviously impossible for a human to completely lack values and political opinions, but what I mean is someone who would actively try to minimize/ignore them. — Skalidris
My two bits worth :Do laws govern the universe? Of course not; how could they, the universe primordial to any law? — tim wood
Would you characterize the world model described above as "Materialism", or "Physicalism", or merely "Atheism"? No information, no patterns, no interrelationships, just atoms whirling in the void? The missing element is Meaning, which is significant only to evolved creatures capable of knowing, and knowing that they know, hence possessing a Self Concept, and the concept of Other Minds.My view is that the world knows nothing of information, knows nothing of anything. It exists as the stuff in it that constitutes it. These things interact in certain ways and not in others. And thus the world goes from this moment to the next. No information, no patterns, just immediate continuous evolution. — tim wood
Another term for that "cottage industry" you mentioned is Philosophy. And yes, Philosophers & Scientists do indeed "define information in peculiar ways". One of those ways is to create imaginary "models" of reality, that are not in themselves real, but ideal*3. Another term for a mental model of reality is Theory. Do you know the real world directly, or only by means of models & theories (a la Kant)?*4a whole cottage industry arises that replies to the world and insists that it must work on models we create, on the basis of information, even to the extent of saying that the world itself just is information!
And the only way that makes any sense is by defining "information" in very peculiar ways, such that "information" and information no longer share meaning. — tim wood
To be clear, the "immaterial power" I was referring to is Logical Reasoning (including mathematics), which seems to have reached its pinnacle of evolution (to date) in the homo species. When we begin to allow non-human posters on this forum, I might need to be more circumspect in my language. :smile:My disagreement with philosophical Materialism is that it ignores or trivializes the immaterial power that allows homo sapiens to post on forums like this. — Gnomon
:lol: That is preposterous that an evolved species would think itself the ultimate ruler of the universe and so they make a god in their own image. — Athena
Plato & Aristotle apparently used abstract non-anthro-morphic notions of "Logos & Prime Mover" intentionally, to avoid implications of the humanoid deities of their day. Similarly, when I occasionally use the term "G*D" when referring to an unknown & unknowable creative/causal power behind the Big Bang, I often use un-gendered pronouns, such as "he/r" and "s/he". But I do so with tongue in cheek, imagining the "huh?" question mark above the head of the reader. :joke:Exactly, however, it might help if we resist using human pronouns when referring to logos or a prime mover. — Athena
If the "detail" you're looking for is empirical evidence, it's probably not forthcoming. Mathematics is a language for science, not an object to be studied under a microscope. Likewise, Energy is an intangible invisible force that is observed only in its physical effects, not as a ding an sich. Both Math & Energy are now regarded, by scientists & philosophers, as forms of Generic Information. Basically most of the referenced links in my posts are philosophical/theoretical generalizations & opinions, not empirical evidence. So, the bottom line is : do you trust these theoretical scientists to know what they are talking about?↪Gnomon
Thank you for the references. I think if you read/listen to them critically, they omit just exactly the detail needed. For example, on the assumption that information is an efficient cause, then how can that work? — tim wood
Yes. The meaning of immortality would be just the sum of meaningful experiences of the observer. Yet the perspective of infinite experiences might eventually merge into a single undifferentiated blob of memory. But, is the whole more than the sum of its parts? Wait and see. :smile:Would life as an immortal real be with less meaning? Can't we just invent it as we go in any event? — TiredThinker
Slightly off-topic : If you will think of Mathematical relationships as A> a form of Information, and B> Information as "the power to enform a mind", plus C> Energy as the power to enform matter (as in E=MC^2), then the notion of a Real universe consisting of mathematical (structural) & informational (meaningful) relationships might begin to make sense. Of course, it's a great leap from Atomism & Materialism.but I think math is the reality, — flannel jesus
I invite you to think about your own remark and the difficulties of it. What if anything can you imagine that would make math more than, other than, just descriptive and give it causal efficacy? — tim wood
JG, I'm not picking on you by posting long dissertations to your name. It's just that I'm on a roll here, expanding the topic of Quantum Entanglement is Holistic. And your math background may allow you to hold apparent paradoxes (counterintuitive results) in your mind, while keeping an open mind --- pax . For example, math has Paradoxes of infinity ; of set theory ; Probability theory : https://en.wikipedia.org/wiki/Category:Mathematical_paradoxes . But those "non-commutative" sub-sets don't invalidate the consistency of mathematics in general. Note --- I'm using that term in an unconventional way.The interplay is certainly interesting. — jgill
Yes. I think you could safely say that Mathematics is a mental philosophical language that is used by Science to describe it's sensory observations precisely. Ancient math concepts were originally devised by desert civilizations -- Egyptians & Mesopotamians -- in order to understand why the stars (gods?) formed patterns that reminded men of terrestrial things & events : Astrology. Later, Greek logicians (e.g Euclid), with cloudier skies, refined geometry to make it more abstract and less subject to variable interpretations : Astronomy."this is the idea that mathematical truths are a byproduct of our linguistic conventions". — Gnomon
The interplay is certainly interesting. — jgill
Yes. That seems to be the point that Heisenberg was making when he said " . . . . it's a question of translation : the conventional language of physics is fashioned according to the world we experience". But most of us don't directly experience the world on the subatomic level. So, it's an abstruse language for sophisticated initiates into the mysteries of the foundations of Reality. And easily misconstrued*1. The current issue (157) of Philosophy Now magazine has an article about Solving The Mystery of Mathematics. For the purposes of this article, the author -- Jared Warren -- rejects the Ideal definition of math as presented by Plato, and also the Real definition of math as "like the physics of this reality". Instead, he prefers a linguistic definition : "this is the idea that mathematical truths are a byproduct of our linguistic conventions".That's nicely done. I suppose my point is that QM is all sophisticated mathematics and equally sophisticated experimental processes. — jgill
Thanks for that quickie quantum update. I assume the article is interesting to Theoretical/Mathematical Physicists. But, can you tell me, in a few jargon-free words, what that account means -- in the real world -- to a non-mathematical layman, or to an atom-smashing CERN physicist, or to a matter-molding Chemist?Here's a quick look at ground zero in quantum studies by Mark John Fernee for Quora: — jgill
After Quantum Physics introduced Uncertainty into Science, and substituted Virtual Particles for Real Atoms, I suspect that quite a few disillusioned undergrads dropped-out of their physics programs. The most famous expression of the "switch" you noted is Feyman's "shut-up and calculate" quip*1. Since then, physics divided into large teams of experimental scientists (atom smashers) and a few individual philosophical (theoretical) scientists. But both groups are "chasing rainbows" that are more & more elusive. Also, the empiricists are typically distrustful of un-tethered Philosophical Reasoning for epistemological knowledge of Material Reality.↪Gnomon
My best friend, who passed away seven years ago, was a physics major up until the required introductory senior level course in quantum theory. He switched to mathematics and retired a fellow professor. A very bright guy - certainly smarter than me - but math made more sense at the time, easier to understand.
I think dropping a physics major at this crucial point of transition in thinking happens fairly frequently. Some become engineers, a profession using physics that moves along Newtonian lines. Well, maybe not so much electrical engineers.
It's a shame the forum doesn't have quantum physicists who might elucidate better than philosophical minded novices. But this is not a physics forum. Our best is not good enough. — jgill
I agree : picture-taking is an observation/intervention, that -- like silver & vampire -- is incompatible with mystery-shrouded superposition. And the irrational "arbitrariness" of the symbol/article juxtaposition is exactly why I started this thread. I was not trying to assert --- as some posters have assumed, and the quoted article seems to imply --- that Yin Yang is a "hard" scientific concept, instead of a "soft" philosophical conjecture.You wouldn't. By the time you can take a picture of something, the quantum superposition has already decohered.
It's good to see you've accepted the arbitrariness of the yin yang symbol in the context of this experiment. — flannel jesus
I didn't "misinterpret the paper", and I didn't "interpret the paper", because I didn't read the technical paper. I did request that others, more qualified, would interpret the significance of the symbol relative to the experiment.Do not assume that just because you managed to misinterpret the meaning of it, that it was MEANT to be misinterpreted. You said yourself that you're not qualified to interpret the paper. — flannel jesus
Thanks for that information. I asked TC where he got the information to support his assertion that the Yin Yang image was both input & output, and he did not respond. I guess I was supposed to take his word for it. But he didn't state his qualifications as an expert on the subject.You posted your opinion implying that the common Yin Yang symbol was used as input... — Gnomon
Have you looked at the original paper? (Which T Clark linked early in the thread.)
I just took a look and the caption under the only picture of the Yin-Yang symbol says:
a, Coincidence image of interference between a reference SPDC state and a state obtained by a pump beam with the shape of a Ying and Yang symbol (shown in the inset). The inset scale is the same as in the main plot. b, Reconstructed amplitude and phase structure of the image imprinted on the unknown pump. — wonderer1
I did not say that. Ignore my evidence if you want, make up your own fantasies about little fairies dancing on the taiji, but don't misrepresent what I wrote. I always thought you were a little goofy, but I didn't think you were dishonest too. — T Clark
My question was not a dichotomy. Merely an incomplete list of unknown possibilities. Maybe they are Alien beings trying to sow discord among PF posters . . . :smile:Did you interpret the symbolic image as an error of judgment, or a deliberate hoax? — Gnomon
Isn't that a false dichotomy?
Maybe a stunt to get a lot of attention to their paper? Maybe one of the researchers is into Taoism? Maybe a target that was handy and interesting enough? — wonderer1
Unfortunately, Logos and Prime Mover might be rejected by Materialists*1 as unprovable Transcendent beings or forces. For me that's not a problem, because they are merely hypothetical philosophical conjectures (thought experiments) or Axioms*2, with no need for empirical proof, only logical consistency. And, since they have no "favorite people", they provide no reason for slavish religious worship. They also have no need to "violate" natural laws, since they are essentially the LawMakers. :smile:Thank you so much! I think our discussions would be much improved the the notions of logos and prime mover. And from there, even the gods were subject to logos. — Athena
Thanks for the reference. The technical stuff is beyond me too. But the references to three different "states" provides fodder for speculation. The "unknown state" must be the entangled photons, and the "quantum state" might be the mathematical wavefunction. But the "reference state" is a mystery.Frankly, I don't know what's going on here. But at the beginning of the paper
: Here we introduce biphoton digital holography, in analogy to off-axis digital holography, where coincidence imaging of the superposition of an unknown state with a reference state is used to perform quantum state tomography.
This stuff is way beyond me. — jgill
didn't respond to my request for the source of his information/opinion about the intentional use of the YY symbol as input instead of as output of the holographic method. Will you post where & how you determined that is the case? Did you interpret the symbolic image as an error of judgment, or a deliberate hoax?The input to the experiment was the image of the yin/yang symbol — T Clark
Seems to be the case as far as I can determine. Difficult reading. — jgill
Since you are reading-into the "4mm", a prejudiced meaning which is not expressed in the image, who should be ashamed? If you can produce evidence to support your "reading", I will retract my attribution of "prejudice". :smile:Maybe, maybe not. The 4mm may be measuring the object under scrutiny, or the photographic image produced by the equipment. Some labels would help. — Gnomon
No sense going on any further. You should be ashamed of yourself. — T Clark
Yes. Materialists, for doctrinal reasons, typically lump Energy into the same ontological category as Matter. Admittedly, Energy is essential to Physics & Chemistry --- and I mean that literally. The common definition of Energy is "ability", but I think "potential" is more accurate : Energy is the potential to cause change in matter. And Potential (not-yet-actual) is by definition, immaterial and unreal --- although its effects on matter are immanent. Energy is indeed a Phenomenon, in the sense of an interpretation of sensory impressions. But the thing being interpreted is itself a Noumenon.Great question. Because that's not what the measurements indicate. Good science shows that these phenomena are part of the material world, but energetic in nature; immaterial.
What's really exciting about all of this, is that the immaterial aspects of this world are present, just waiting to be rediscovered. That is what entices me, as an individual. — Bret Bernhoft
Yes. I had imagined quantum entanglement as random noise, and the dis-entangled particle as a recognizable image. It never occurred to me that a tangle of photons would look like a Taoist symbol. :smile:Yet, this is not the point. We are talking about just a visualization. Nothing more. — Alkis Piskas
Maybe, maybe not. The 4mm may be measuring the object under scrutiny, or the photographic image produced by the equipment. Some labels would help.Here's a figure from the article from which you've clipped your yin/yang symbol. It shows the black and white input image and the colored output. Note the size, measured as 4mm, or about 1/4 inch. This does not show entangled photons, it shows the recreation of an image. — T Clark
Good Point! For all practical purposes, and within the here & now world, I am essentially an Atheist, but I prefer the more modest & philosophical label Agnostic. Even so, the physicalistic/materialistic Big Bang theory, was formulated with the unprovable assumption (axiom) that Energy & Natural Laws pre-existed the Bang.I am not sure but I think the big divide between materials and the spiritualist is disagreement about the source of the energy that makes life possible. — Athena
Yes, I'm familiar with Capra's seminal work. But, I doubt that even he, as a physicist, would imagine that entangled photons would graphically resemble an ancient symbol of harmony & balance. :smile:Gnomon, Fritjof Capra has talked about this subject extensively since 1975 in his famous book "The Tao of Physics: An Exploration of the Parallels Between Modern Physics and Eastern Mysticism" — Alkis Piskas
I certainly don't understand why an attempt to create an image of a "physical" object would require the inclusion of a completely unrelated image. Which part of the published picture are we supposed to identify with the entangled wavefunctions? Even if the swirling dots are supposed to be entwined photons, what scientific meaning are we supposed to learn from the image? An artist could have done the same with much less technological tomfoolery. Were the scientists themselves "gullible new-agers" trying to send a message to blind black-&-whiters?No, you've completely misunderstood. As punos noted:
They made a bad choice in using the taiji because gullible new-agers could so easily jump to the incorrect conclusion without understanding the substance of the experiment. — T Clark
Is it your understanding that the scientists took a picture of a cultural symbol, and published it as-if it's a picture of two photons orbiting each other?*4 If so, was it a joke on gullible New Agers?*5 Or were they deliberately trying to deceive us ignorant Philosophers? Either way, it's unprofessional behavior. Please post a quote from your source that says "The input to the experiment was the image of the yin/yang symbol", so we can "take a look".After slogging through the original paper (link - https://www.nature.com/articles/s41566-023-01272-3#Fig2) I think I've sort of figured it out. Not certain. If I'm right, you've misunderstood what's really going on. The input to the experiment was the image of the yin/yang symbol. It was disrupted and then recreated using the new holographic/entangled photon technique. Somebody else take a look and see if they think I'm right. — T Clark
This thread seems to have diverged into a debate on Physics (energy, matter) instead of Metaphysics (abstract concepts such as being, knowing, substance, cause, identity, time, and space). But the OP seems to be implying a metaphysical (philosophical) distinction : Theism postulates non-physical (metaphysical) causes, while Materialism denies anything non-physical. Yet even Materialists must accept the existence of causal Energy, even though scientists don't know what it is (ontology) -- only what it does (epistemology)*1.Energy being physical is fairly well established. If you want to get into a more wonky question there is the matter of it information is physical (Landauer's Principle) and there remains some hot debate on that.
But, if information because essential for explaining cause in a way that people do not think is somehow an epistemic artifact, I imagine we'd see widespread acceptance of information as physical (it's already a majority opinion I would think). — Count Timothy von Icarus
I apologize for offering you novel ideas that your background didn't prepare you to understand. But the scientific terminology I used, by analogy, did represent my unconventional meaning. So, it was not intended to mislead.That's why I commented. You shouldn't appropriate scientific terminology in a way that misrepresents it's meaning. — T Clark
You could say that what defines a unique ability of homo sapiens is that "we know that we know, and we can communicate that knowledge in words". Although, as drag-on disputes on this forum indicate, the communication is imperfect. :smile:Having rowed back on analogy as a human USP, what then defines our ability? I would posit the following as specifically human (but now without complete confidence!): — Christopher Burke
Your defensive skepticism missed the point. It's just an analogy.These are not the Laws of Thermodynamics, they're the Laws of Gnomodynamics. — T Clark
FWIW, here are some thoughts on the relation between Enformy (the natural tendency to create and transform material objects) and Energy. You won't find that term in any science books, because I coined it to express an underlying relationship that is more useful for philosophical reasoning than for empirical manipulation of matter. There's lots more where this came from, but it's not in the category of settled science. Again, it's not a factual "claim", but a philosophical conjecture about the role of Form in the world. Plato & Aristotle used that idea long before anyone had the modern concept of physical Energy. :smile:No, I don't find such a claim convincing, when you offer no supporting empirical evidence. — universeness
Do you require empirical evidence for a "philosophical thesis*1"? Most philosophical assertions are supported by argumentation, that you can accept or reject for personal reasons, but can't disprove empirically --- only by authority.No, I don't find such a claim convincing, when you offer no supporting empirical evidence. — universeness
I don't want to sound obtuse, but "role of observation"*1 and "observer effect"*2 are different in what sense? Does, or does not, experimental observation (looking + perturbing) have an empirical effect on the object of the experiment? As I said, I don't think "just looking" can cause a change in matter. But a quantum-scale scientific observation involves more than just passively seeing what happens. So here, I'll try to answer my own question.I'll say it again one more time and leave it at that. No... I won't say it again, I'll just copy my previous comment here:
The possible role of observation in "collapsing the wavefunction" or whatever is a completely different phenomenon than the observer effect. — T Clark — T Clark
For me, that was just a guess. I'm not an expert in animal psychology. But I see videos on YouTube of animals that seem to make analogies in order to judge relationships. For example, a crow who imagines that a stick could be an extension of its beak to reach a morsel in a jar.That is a very big claim. It obviously can't be proved, but what aspects of animal behaviour make you think that is plausible? I believe that analogical thinking is uniquely human, because no other species produces symbolic artefacts or behaves in ways indicating such abstraction. Am I wrong here? I'd be interested to know. — Christopher Burke
You don't find my postulation convincing? How do you explain the "change"? It was a personal philosophical guess, based on the discussion above. I didn't ask you to accept it as a fact, just something to think about. I'm not a quantum scientist, so challenging me to "prove it" on a philosophy forum is not appropriate.That's why I think the "collapse" (change) occurs in a mind (Voila!), not in a particle of matter. — Gnomon
We just can't take your word for that. You need to prove it's true! — universeness
I'm not sure I understand what you are implying. That an observation (or perturbation) precedes the so-called "collapse" is not in question. But "correlation does not prove causation". In my quoted definition above, "The observer effect is the fact that observing a situation or phenomenon necessarily changes it". The crux of the controversy seems to lie in the difference between "observation" and "perturbation". Does witnessing an event (the role of observation) cause the event, or does the physical disturbance by experimental apparatus cause the noted change?The possible role of observation in "collapsing the wavefunction" or whatever is a completely different phenomenon than the observer effect. — T Clark
