Let me make it simple.

A circle has an interior and an exterior separated by a topological distinction - a boundary. Its mathematical definition is simple too - r equals a constant (one perhaps), where r is the radius of the circle. But of course; that same definition also designates a whole family of figures we call spheres. If we have an empty space, absent of topological form - an unbroken expanse - this is a different animal. Placing an observer anywhere in that expanse, as pointed out by Tom Ray in his essay, induces a sense of toward and away; I like to say that observation is centric, and so nearby and distant become defined in relation to a particular center - the location of the observer.

If we trace on an empty piece of paper, all of the points equidistant from a given center, we end up with a circle. I like circles, and they were one of the first conscious symbols employed by our ancestors, but they are also the simplest possible example of a figure with a continuous boundary, where the one-dimensional version is a pair of points - which is not continuous. Remember the definition for a unit circle - r equals one. That formula also defines the unit sphere - but it is not a trivial matter that all of the higher-order spheres are defined likewise.

Let me explain. In constructive geometry nothing is assumed to exist, besides an unbroken space of unknown dimension, until some (constructive) process of determination allows a statement to be made. A very cool thing is that constructive proofs actually allow you to construct the object under study, so they are very useful both to humans and to nature - assuming only that natural evolution makes sense logically/geometrically. But I would argue that the universe we observe didn't just happen, so Physics MUST consider how observable form first came to be.

I'll continue below,

Jonathan

    From a cognitive perspective;

    We come into the world with few or no assumptions, and a fuzzy perception of ourselves and the universe. At birth; we have no clear sense of self and other, or location and surroundings. Clearly, any one infant occupies a specific location, has a well-defined topological boundary, and so forth. But there is some evidence that neonatals do not distinguish between self and others or environment, and perceive all of it as a continuum. In this way; they start with an unbroken reality of unknown dimension, just like constructive geometers.

    One could draw an analogy to algebraic rules. Determining what is part of, or inside of, what (interiority/exteriority) is like learning the associative property, and determining what is bigger/smaller and nearer/farther is like learning the commutative property. Interestingly; while rotations on the surface are commutative (so the illusion is complete) 3-d rotations are not - so children born in space might grow up with an intimate knowledge and visceral understanding of non-commutative geometry.

    Anyhow; I boldly assert that the process by which we learn about nature and the process by which nature created the form we see around us is one and the same. That is; in any creative process or any learning process, levels of abstraction need to be evolved or unfolded, and procedural steps and/or process stages need to be realized. One could say that possibilities lead to actualities, but then specific actualities make new things possible or evident. In my view; this scheme describes both bits of knowledge or perceptions and bits of structure or objects.

    I'll talk about how that answers 'what 4 or 5 assumptions?' in more detail next.

      Hi Jonathan,

      I think you are making an important point. That our normal perception of the way things are is due to the development of the brain and its capacity to make sense of the sensory data it receives from the environment.

      However , you wrote: "It is now known that neonatal infants do not distinguish between themselves and their surroundings or environment." I wonder whether that is a false notion based upon attempted interpretation of responses. There is not yet the ability to read a newborn's mind.

      Like a number of other people, I have retained some pre-birth and very early life memories. My personal realisation of the limits of my existence occurred in utero. Prior to that I was self aware but with no perceived spatial limits. I can't of course prove that, but I do know it. I presume the transition in awareness was around the same time as the nerves from my fingers and toes began sending sensory impulses to the brain, which could be interpreted by it as being from my extremities. So subsequent to a certain level of development of the nervous system. I was most definitely aware of my separateness and individuality and the separateness and individuality of other people in my local environment at the time of birth.

      Jill Bolte Taylor's video is very interesting giving an account of a perspective that thankfully relatively few of us get to experience. I.e. To have conscious awareness of the unprocessed (,or ill / under processed) sensory data input during a stroke. It is good evidence of the 'division' between the material world and the image that we have of it. Which provokes the question -what is each area of physics modelling? The perceived image, the sensory data, or the material sources of data.

      Perhaps not quite irrelevant Paul.

      If Georgina and I have pointed out that you are doing a bit too much pre-filtering or pre-processing - which we do not confuse with the issue of subsequent processing as you seemingly do. Come on Paul; you are trying to ride a dead horse. You are a victim perhaps of a confirmation bias, but one which somehow locks out the continuous aspect of reality described in the papers I cited by Zeh, and highlighted in the article by David Tong in the December Scientific American, which was one of last year's FQXi contest essays.

      A comment in Sci Am about the way things turned out last year focused on there being more writers who favored an analog view than expected. But trying to push objective materialism on theoretical physicists as you do, gets a bit stale. I appreciate that you bring the conversations down to Earth sometimes, and help to keep things real. But to assert that Physics should stick to describing only that portion of reality that adheres to objective realism, is somehow a bit unrealistic IMO. I will try to focus more on the Physics, but if some pre-conditioning on your part (or mine) makes important or relevant points appear irrelevant, the reasons why our views differ must be examined - before we can determine it to be a perceptual matter or about the Physics.

      Regards,

      Jonathan

      Jonathan,

      I have disagreed with your portrayal of the newborn's cognition following your earlier reply to Paul. However I am not disagreeing with the important point you are making about the necessity of learning about geometry and spatial relations of things. That growing cognition goes along with development of motor skills to interact with the environment, exploring, experimenting and building mental models.

      I was looking for the sensory deprivation experiment done on kittens, who were shown only vertical lines, resulting in a kind of blindness to horizontal lines presented later on. Found This- Slideshow re. Perception I think that summary clearly shows that the mental models that are built, though enabling us to function well in our environment, are not infallible representations of the external material reality.

      Thanks so much for chiming in Georgina.

      I think it is unavoidable that we sometimes end up modeling our perceptions of reality, rather than the tangible and measurable part of it. This is unavoidable, even in Physics, and the only way to make sense of things sometimes is to recognize that we are mired in a lot of givens, some of which are perceptual - and trying to step back from ourselves always, or step aside to see reality for what it is. The really tricky piece is distinguishing which kinds of bias are in play at any point.

      I think Jill Bolte Taylor is a godsend and I find her work very liberating, being a more right-brain centered person than most. I spend a lot of my time writing and performing music, so I can absorb myself in non-verbal realities - but I know how hard that can be. Some meditation experts assert that setting the internal dialog aside for as little as 45 seconds can liberate one completely from the illusion of separateness. But that 45 seconds could be an eternity for most folks - as even 5 or 10 seconds of silence is a lot.

      I will try to find the studies asserting the infant's state of relative oneness, but I am happy to hear you retain some awareness, or were lucky enough to wake up in the womb on occasion - before you were born. That sounds like a wonderful thing to have a recollection of; it must be a comforting memory to return to.

      All the Best,

      Jonathan

      Hi Folks,

      I see the contest is drawing to a close. However; it has been and remains engaging for me to interact here on the FQXi forum, especially on this and your other essay pages. I expect to be available to respond to questions and comments for some time, but I apologize if it takes a little longer. I'll treat any honest queries and comments respectfully, including any open threads of conversations above.

      This year's topic was one I felt especially well suited to answer, having posed it as a suggestion for last year's contest. Or rather; FQXi chose an essay question that was a variation on one I'd suggested. You can read the story of my experiences at CCC-2 in the essay, to learn why I did so. It was there I first learned that just changing one or two key assumptions can completely alter the face of cosmology and our picture of the universe.

      Two other entrants in this contest - Avtar Singh and Don Wilson - also attended that conference, so they know whereof I speak. But I've since attended talks by some of the respected founders of our current view - like Paul Steinhardt - who now assert that we need to question some of our key assumptions in cosmology very seriously, because otherwise there are gaping holes in the fabric of our knowledge about the cosmos. So I commend FQXi for choosing a wonderful question that let such a great number of participants tell the story a different way.

      Regards,

      Jonathan

      All this concern over how the processing of received physical input works is irrelevant to a physical theory. A physical theory, which is an attempt to explain physical existence physically, cannot be reliant on the vagaries of how sensory receptors decode what is received, brains interpret, memory, cultural influences, etc, etc. It is relevant in that, as with anything, it would be good to have an answer. That is, when in receipt of physically existent entity X, what happens in a generic human being, or a bat, or a plant (the latter alludes to another tendency to only consider humans, and in respect of observation). The point, as it should do, applies to any sentient organism, and any sensory capability.

      Another way of putting this is that following on from an exchange initiated in Ben's blog, I have asked Georgina in her blog: "How do what you call Object & Image Reality have a physical relationship?"

      It is not "pre-filtering or pre-processing". I am just stopping at the point in time when the physically existent phenomena are received, since that interaction also results in the cessation of those physical phenomena. That's the physics. So contrary to your next assertion: "which we do not confuse with the issue of subsequent processing as you seemingly do", I am the one not confusing perception/knowledge with reality. More importantly, I am the one differentiating a 'representational reality', which is a physically existent phenomenon, from (for want of a better label) existential reality. In simple terms, there is light, nose, vibration, heat, etc and there is (or more precisely was) what caused that.

      Neither am I a "victim perhaps of a confirmation bias" because all I am doing is confirming the existentially closed system we are trapped in. Indeed, here is the fundamental argument (again), if you can see any presumption, please let me know:

      1 There is existence of some form or other.

      2 We are enabled to be aware of existence via certain physical processes.

      3 We are therefore aware of what must, logically, be presumed to be only one possible form of existence. However, that is irrelevant in so far as we cannot transcend our existence, ie we cannot know, either directly or indirectly, something we are not capable of knowing. So, whilst we must assume we are trapped in an existentially closed system, within that we can potentially know everything. The basis of validation being those awareness processes, preferably when effected directly, but properly derived indirect 'awareness' is acceptable.

      4 There are two key features of the form of existence that we can know:

      a) it exists independently of the processes which detect it

      b) there are differences, ie there is alteration.

      This means the form of existence we can know (call it physical existence) is existential sequence.

      5 In such a sequence, for any given successor to exist, the predecessor must cease to exist. That is, in physical existence, there can only be one physically existent state of the elementary substance which comprises it, at a time.

      6 The physical processes which enable awareness have evolved using certain physically existent phenomena which have a particular generic characteristic. So, while they are part of physical existence, from the perspective of the recipient detection processes, they are representations of (what might be labelled) existential reality). That is, they resulted from a physical interaction with that existential reality. Indeed, if it was not for the evolution of those detection processes, they would be of no significance. In fact, if intercepted by an inanimate object, as opposed to the receptor device of any detection system, then they cease to exist and have had no significance.

      End of.

      The subsequent processing of this physically received input is irrelevant to the physics. Unfortunately(!) it is the only source from which to start determining what actually happened.

      "In constructive geometry nothing is assumed to exist, besides an unbroken space of unknown dimension"

      But is this a proper representation of physical existence? Because we do not know that 'nothing exists'. What we do know is that there is 'stuff', of different types, and depending on what we define, then there is 'space or 'distance' between those 'stuffs(!)'. But this space or distance is not, of itself physically existent, it is the different (in respect of a certain attribute, ie spatial rather than (say) colour) between what does exist. Differences do not physically exist. Indeed, that particular difference, can only be identified when the entities concerned are physically existent at the same given time. There is no spatial difference between something which exists and something else which does not exist. Put two jars on the table. There is a distance. Take one away. There is no distance. [That is the key flaw in relativity, because if that is not understood, then distance acquires duration via an incorrect application of x=vt]

      The other question could be along the lines of what have spheres got to do with it, what is the justification of using spheres to represent physical existence? But that is detail.

      The other point is about observation. Somewhat obviously, the physical entity that enables observation (aka light) must be 'coming towards', ie it and the front end of the sight sensory system (aka eye) must coalesce in their line of travel. Otherwise that particular light will not be 'seen' (which really means decoded), it will interact with the brick wall beside you perhaps. Or if it had been travelling in another direct, it might hit another observer, or another brick wall, or continue on in the general direction of the Andromeda Galaxy, etc, etc. The point here is that this entity, commonly known as light, is a different entity from what the original photon reacted with, which is commonly known as reality. What we physically receive, is not reality, but a reality which, in the context of the detection systems (commonly known as senses) provides an independent, physically existent, representation of that existent reality. After that it is a nightmare! commonly known as processing what was physically received, but that is not physics.

      The reality of light, is different from the existential reality. Though, obviously, both need to be understood (as does the reality of noise, vibration, etc, etc). The fatal trap is not to differentiate these two. [Which is what relativity does to rationalise time which has been incorrectly introduced as a variable through the misunderstanding of how to measure distance]. However, I would just say, as I have before, that one then needs to be practical. For many occasions, can we just carry on with the science on the basis of a simplification, ie conflating physical existence, with the observable reality of physical existence (ie light reality = existent reality, and the 'nightmare' is neutralised, that is individualistic variations, etc, are eliminated). But that has to be a conscious decision, and when appropriate, that differentiation must be maintained.

      I think it is sufficient to say that this all concerns processing-see above.

      On the subject of my supposed 4 or 5 assumptions, I have somewhat pr-empted that with a restatment of the argument above, though I did react to some of your original articulation as to what you thought my presumptions were.

      Anyway.....but do remember, we have to start somewhere, so one cannot just declare it a presumption because it was the start point, as such. And, as I said previously, what is more important is, does it work and do hypotheses based on alternatives not work?

      Paul

      Thanks greatly Paul.

      I agree we have to start somewhere, but I have limited time today - if I actually do what I am supposed to get done (I'll probably get drawn into something). However I have some papers in the works and other cool stuff in the pipeline, I need to get back to as well. I do value your thoughts and your opinion, so I will be getting around to this thread and your open questions. If you are patient; I will attempt to address all the points you made.

      Regards,

      I am still being patient!

      I think though, while obviously a response to my particular points above is good, a better approach might be to respond to something where I articulate most of them in a cohesive statement which addresses, in detail, the fundamental error, ie the misuse of x=vt. This was posted on my blog in mid November, but if you send me a link to paulwhatsit@msn.com, I will send you a copy (it's only 12 pages).

      This might help you understand where I am 'coming from'.

      Assuming there is 'something wrong', the following are immediately apparent:

      1 The theory 'works', which means if there is something wrong, then there must be compensatory errors or the incorrect attribution of a real variable.

      2 If there is something wrong, it has nothing to do with the subsequent processing of physical input received. Nowhere is this the argument advanced, and it must not be that anyway, a physical theory cannot be a function of the vagaries of sentient organisms. Physical existence is independent of that.

      3 In any practical sense, light travels at near enough a constant speed, so approximating to such, cannot cause a logical issue. Which indicates that the real problem is, if there is one, something else associated with light.

      Then when one reads the originals, which are simple narratives (the maths does not matter in the first instance), two features 'jump' off the pages:

      -that the two postulates deployed, which are singularly non controversial, are "only apparently irreconcilable". This is a bizarre statement, new theory, just two postulates, and yet......

      -the pre-occupation with 'stationary' and non-stationary motion, and how something occurs in the latter circumstance which renders previous methodologies inadequate. What is this new feature that has been missed previously? How does being caused to move at a relatively different speed result in some physical effect which needs to be factored in when calibrating motion?

      The answer lies in the hypothesis of dimension alteration. The twist in the story is that they ultimately ignored it, and accounted for the real variable by wrongly attributing its cause. Dimension alteration just affected their train of thought, and was the background to this preoccupation with stationary/non stationary movement. Now, it may just be that the dimension of all (some types) entities is affected by differential force incurred, but that is a separate issue...

      Dear Jonathan,

      Recently, a price was awarded for hearing aids that mimic binaural signal processing already before the neural cross-links between left and right cochlear nuclei. The solution by Siemens uses em waves for performing the due transfer between left and right side as to improve spatial hearing of elderly people and their ability to suppress noise (cocktail party effect) by means of coincidence detection between the binaural signals. The perception of elevation in space is more difficult.

      I vaguely recall a report that unborn babies are already able to hear. Anyway, the interplay between left and right auditory pathway is definitely to be found already in embryos.

      I admire your patience with Paul.

      Best,

      Eckard

      How sentient organisms process what is physically received is irrelevant to a theory of physical existence. It enables a better understanding of what was received, and the elimination of influences introduced in that processing. But physics is explaining, on the basis of what was physically received, what physically occurred.

      And the same point is that Einstein never said it was anything to do with the processing of what was observered, just that it was observed, ie light was received. Problem is, he did not differentiate that 'reality' from the existent reality that is represents, in the context of the recipient sight sensory system. And therefore attributed the ever present time delay, whilst light trvels, to the wrong factor.

      Paul
