Dear Marina,

Congratulations for a very nicely written essay.

Yes "Quantum milieu must differ somehow from both space and spacetime".

We have found that projective geometry, including Flatland, still play an immense role in the quantum observations. If you have time you may have a look, and some insights, about the 'dessins d'enfants' that I introduce in my essay.

Good luck,

Michel

Dear Marina,

You have give me good lesson! Maybe I am actually more pessimist than necessary. It is maybe because I am not so young and you can be right on this point. Now new generation is grooving up who already do not want the false! It gave some hope on future. Your work is nice by its trust, and I appreciate it by 8 point with clean heart.

I am very hopeful you will not outsider!

With best wishes,

George

Dear Yuri,

glad to see you again and thank you for reading and commenting on my essay. It is hard to find a quiet moment in this holiday bustle to read and comment on so many essays! The precise context of quote you refer to escapes me at the moment. But I think it may relate more to your essay than mine. I will read and comment on it when I get a chance.

I wish you fun bbq and spectacular fireworks :)

Dear Dr Vasilyeva,

I like your idea that information is repeatedly re-absorbed by reality. It's a very logical argument and immediately made me think of fractals. So glad to see these mentioned.

Original and one of my favourite essays so far!

My essay based partly around the Fibonacci sequence will hopefully be of interest to you.

Excellent work - well done!

Antony

Dear Vasilyeva:

I congratulated you because with your essay seemed to me that help people to come down to earth. I appreciate that your view of my essay as unique, refer to that nobody know, or ever had my view including the greatest minds of mankind. This make me feel as a stupid, just because I can see that I was unable to take the mysterious time down to earth as my whish was. I don't pretend, or even try to pretend to compare myself with those great thinkers. In fact was a luck strike (like cigarettes) it happen in around two hours, when I was young, just several synapses that close this unique circuit, what I really consider myself a merit, was to immediately realize that what I find out was the most transcendental thing I was going to do in my whole intelectual life, the next day I realize that it was good for nothing, so I living rest for more than 35 years, when suddenly I find that theoretical physics was in a serious need of what I find out . "Time" not definition but what experimentally mean "motion", like I said is just a remnant word but people just borne with the word "time" stuck in their heads and it is like that, at least for the last 25 hundred years , as you said "the arrow of time", "the flow" "direction" and bla, bla. I try ten or fifteen different approaches to make clear that what people measure is "motion" and no the mysterious "time", but none of the people that look at the essay understood what I said. You know things happen once for the first time. When you said : "your answer to the question of the ever-elusive 'now'. I also find your apparent aversion to . in the end of a sentence intriguing, as if you never want it to end or perhaps to be so crudely extracted and separated from the continuous flow of the context it is in. This makes a vivid illustration to the main theme of your essay." You are becoming a better psychiatrist that I am . Of what you are right is that "I did not want to end" but I have to, because I did reach the 25 hundreds characters allowed. I don't care about physics, just I don't like to throw away those two hours, these are not common ones What I am afraid is that I am going to leave and take with me this find, and I hope it will not take another 25 hundred years to find it again.

Best whishes

Héctor

Dear Marina,

This years essay did not disappoint. I believe your perceptions are excellent, including 'recursive loops', sensor dependency, limbic system processing, that "output, or new information, is always generated at the boundary that separates two different environments", and that "participatory scheme... implies that reality is a local phenomenon, perpetually generated anew, emerging as the result of exchange of information", and also that; "It' is space'.

May I suggest those puzzle pieces may be even more powerful than you realise if coherently combined with the minimum new understanding. So where "The situation appears hopeless" the solution is literally right before our eyes.

'Right before our eyes' is a change of medium, a "boundary that separates two different environments", where light refracts and "generates anew" the information, the new wavelength (if the lens is 'in motion') to send to the brain to process, by applying 'time'.

If, to a 3rd party observer, the speed of light is changed to the new local c at the boundary of the lens by interaction or waves with with quanta ("many small" atomic scattering events), then Special Relativity logically emerges direct from the Quantum Mechanism. The question is resolved.

You may recall I discussed this in last years essay, pointing out that space itself contains many such particle 'shock' boundaries. I elucidate on that this year, showing the power of that model of 'discrete fields' (DFM) just an assembly of the concepts you so well describe, viewed from a fresh angle. I hope you'll be able to read mine and comment.

Very well done on yours, a pleasure to read, incisive, relevant, very nicely written and argued, and for me very harmonic. Would you accept perhaps one suggested change, to add 'refraction' to 'reflection' as a boundary process.?

I hope it does very well in the contest.

Very best wishes

Peter

Marina,

I was intrigued by your essay especially the sentence : Reality is continuesly emerging anew....

There you really are touching my preception.

About the various creatures , of course there are various forms of consciousness, forms that are not acessible to our five senses feeded consciousness, our awareness is only one aspect of the whole spectrum of information that is "available". In an earlier paper (http://fqxi.org/community/forum/topic/913) "THE CONSCIOUSNESS CONNECTION" I introduced the so called "Subjective Simultaneity Sphere" with in its center a singularity called "consciousness" that is the origin of the reality awareness of an individual, of course this counts for every form of creature.

The what you call "participation" (page 3) is an effect of decoherence in my view.

I hope that you can read, comment and also rate (I am not a professional !) my essay : "THE QUEST FOR THE PRIMAL SEQUENCE"

Wilhelmus

    Sorry marina, I forgot to log in, anonymus is Wilhelmus. (the rating succeeded when not logged in...)

    Marina,

    Thank you for your kind comments on my thread. I reread your entry and it is a very clear, insightful and sensible analysis of the field of physics. I find myself somewhat outside the fold though. I don't think we can understand information only in terms of other information. I think its properties and limitations are largely determined by the nature of energy as medium. If it were up to information alone, it would propagate endlessly and only be limited by informational conflicts. In order for new information to be created, old is erased, which goes against the idea information is never lost. This goes to my argument about time, that it is not a vector from past to future, but change causing future to become past. Duration is only a measure of the dynamic process and is the state of what is present, not a vector on which present moves. I think the relationship between energy and information is not only similar to, but part of the relation between radiation and mass. In fact, it is the tendency to apply the structural confines of mass/information, to energy/radiation, which biases our understanding of this side of the cycle. For instance, I suspect we will come to understand how redshift is a natural effect of radiation expanding out on release and received as samplings, rather than traveling as point particles over intergalactic distances.

    On a personal level, I don't have the time or talent to pursue these debates to the degree they need, so I try to stick to very basic debating points and not expose my limitations too much.

    Marina

    Amongst other things on my essay blog you pointed me to your comments on SR.

    Now, had Einstein done what he said he was going to do, then it would be a 'theory of the relativity of information' (as you phrase it). But he didn't, so it isn't. It is just wrong.

    There are two phases to explaining this:

    1 What actually is SR.

    As defined by Einstein, SR involves:

    -only motion that is uniform rectilinear and non-rotary

    -only fixed shape bodies

    -only light which travels in straight lines at a constant speed

    In other words a state of stillness where nothing, relatively, is happening. It is special because there is no gravitational force (or more precisely, no differential in the gravitational forces incurred). It is not 1905, but his attempt to resolve the 'apparent irreconcilability' of the two postulates. Had the light in Einstein's second postulate been observational light, ie light which enables sight, which is what it was meant to be, then this state is the only circumstance in which the two postulates reconcile. But there is no observation in Einstein, because there is nothing to observe with. There is always some form of light, but it is just being used as a constant against which to calibrate distance and duration. Nobody sees with it. So the second postulate was not deployed as defined, and the attempts to reconcile rate of change and constancy of light speed are pointless, because the issue is non existent.

    2 So the question becomes, what is relativity. The closest Einstein got to admitting what he had, in effect said, is:

    Einstein para 4 section 9 1916

    "Events which are simultaneous with reference to the embankment are not simultaneous with respect to the train, and vice versa (relativity of simultaneity). Every reference-body (co-ordinate system) has its own particular time; unless we are told the reference-body to which the statement of time refers, there is no meaning in a statement of the time of an event. Now before the advent of the theory of relativity it had always tacitly been assumed in physics that the statement of time had an absolute significance, ie that it is independent of the state of motion of the body of reference. But we have just seen that this assumption is incompatible with the most natural definition of simultaneity; if we discard this assumption, then the conflict between the law of the propagation of light in vacuo and the principle of relativity (developed in section 7) disappears".

    What has happened here is that since he conflated reality and the light based representation thereof, because he has no observational light, he has confused the time of occurrence of reality, with the time of receipt of a light based repreentation of it. So, in effect, his relativity amounts to existence occurring at different times. Which it obviously does not. In other words, he has shifted the time delay which does occur in the receipt of light, depending on spatial position, to the other end of the process, ie existence. He creates the ability to do this by failing to understand how time works. That is, he equates time with what timing devices tell it to be. Whereas the reference for timing is a conceptual constant rate of change to which all devices are synchronised, within the realms of practicality. So his concept of simultaneity in effect creates an xtra layer of time wich does not exist (he called it "common time").

    Reality, which is a discrete definitive physically existent sate of whatever comprises it, occurs at a time. In doing so a light based representation of that occurrence is generated. This is received at a later time.

    Dear Marina,

    I just read your essay and would like to provide my feedback.

    First, the title: It strikes me as perhaps the most lyrical of all the entries, but that by itself is not a big deal; (most) anyone can come up with lyrical expressions of some sort or another. To make it lyrical and to have it precisely sum up the body of the essay is to me a form of art, and you did it.

    Second, the body: The approach followed in your essay is consistent with the informal tone you set at the beginning. But informal does not mean that there are not some important insights to be shared. I gleaned three major ones:

    1) "...each kind of creature perceives the world through its own set of narrow bands on various spectra of available information..." How true! I have sometimes tried to imagine what the world would be like if I could perceive it as some of the animals you mentioned (and others) do. Surely it would be very different. You can see just from astronomical pictures that the world looks quite different at different wavelengths. If the temperature of the sun were a just a bit different, we would have probably evolved sight within a visible spectrum that is different from our actual one. Perhaps, instead of using Magnesium to make chlorophyll, plants would have used iron to make hemoglobin-like compounds to perform photosynthesis (This is actually a research subject). Then plants would be red instead of green. I'm sure your friend wouldn't mind, though.

    But seriously, the fact that this is so often forgotten is just another reflection of the the anthropocentric aspect that is imperceptibly interwoven in our worldview, which brings me to the second insight

    2) "It [i.e. Wheeler's purported scheme whereby everything is reducible to the apparatus-elicited answer of a yes or no question] is limiting because it presupposes an a priori knowledge about both the universe at large and every specific thing in it..." I have now read many entries to this contest, and a fair number of them mentioned Wheeler's scheme, but none pointed out this implication, it did not even occur to me. But you are absolutely right, one can't ask yes or no questions about things about which one has no inkling and I agree that this is a serious limitation of his scheme. I think you have uncovered an anthropocentric facet that goes beyond the talk about measurement devices and questions because it makes plain that his scheme depends in an unmitigable manner on the observer's prior knowledge.

    3) "From here it is natural to infer that it [i.e. participation] must also hold true for each and every thing in existence." I think this is a profound thought. Consider how many philosophers have tried to (unsuccessfully) define "existence". For example, if you look at the entry in the Stanford Encyclopedia of philosophy, you will find a lengthy article which fails to come to a conclusion. I have myself pondered the question for a long time (in fact, I have an essay in preparation which is tentatively titled "Quantum Mechanics and Existence"). If your approach works, then it can be used as a working definition for physical existence. The main question I would have is in what ways you would differentiate between 'participation' and a physical interaction. You have presented a cyclic schema, but it seems to me that one could label the steps also as components of interactions, though your discussion of the applicability of this schema in quantum mechanics suggests an approach for differentiating between them.

    In any event, thinking of participation in this generalized sense seems to me immensely more sensible and fruitful than thinking of it in terms of the anthropic principle (you can probably tell that I am not a fan of it).

    Here are some other short comments:

    -the phrase "Grappling in the dark..." sounds vaguely familiar, where did I encounter this before?

    -I also like the humor in your essay. I'm curious about the Russian expression, because I thought hamburgers were an American invention

    -I think I got the general idea behind the fractal waves, but I think as you stated it, it may easily give one the impression that you are raising the possibility of superluminal signal transmission or information transfer. I would probably have been better to flesh out the idea some more. It may well be that there are locally causal chains of which we are not aware at a conscious level, but which we recognize subconsciously , and which would therefore, upon encounter with the effects of the first few members of the chain, trigger the kind of reaction that you mentioned.

    I enjoyed your insightful and fun essay very much and wish you all the best,

    Armin

      Hello Marina,

      I think yours is an interesting essay, well written and easy to read (apart from a few spelling glitches).

      I think it's appropriate that you discuss the rich variety of information captured by nature's plants, animals and other organisms - it's easy to forget that other organisms routinely acquire information about the world that is different to the information we acquire - whether it is sensitivity to different frequencies of sound waves or different wavelengths of light, or more acute sight or sensitivity to minute electric currents.

      I liked the bit where you question Wheeler's "apparatus-elicited answers to yes-or-no questions" idea as "both limiting and impractical". I found your discussion relating to Wheeler's "participatory universe" interesting, though I think that the "participatory universe" idea should perhaps also be questioned because, as you described it, it might seem that there is no essential difference between the participation of a sausage and the participation of a person! I personally think his "participatory universe" idea is of value, but of limited value.

      In your final discussion where you talk about "each participating event, or a process", are you talking about subjects? If not, if reality is just "a process of active information exchange", what is it that differentiates anything so that it can be described as an event or a process?

      Cheers,

      Lorraine

        Thank you Armin for your feedback!

        Re: 'existence' I do not pretend to have a better definition than you or many philosophers in history have suggested. I only responded to Wheeler's idea of 'participation in the universe'. You ask, "in what ways you would differentiate between 'participation' and a physical interaction." I don't. However, in terms of information as knowledge of something, it is self-evident that unless two processes interact, either directly or indirectly, they remain ignorant of each other. In other words, one knows of existence of only those processes with which one interacts within the same shared milieu.

        .

        Re: fractal waves and an impression that I am "raising the possibility of superluminal signal transmission or information transfer" -- not really. I merely point out that if it is shaped as a fractal, then information about the 'main event' arrives before the event itself.

        In real life situation, a good example is an approaching thunder storm. There are many smaller events heralding its arrival, like, say, positive charge building up on the ground -- but of course there are many, many others. If you look around, even the 'dumb' insects 'know' when the storm is coming. They stop flying around and instead seek out shelter, which they find beneath the leaves, where they just sit, waiting (and look very cute doing it, I may add).

        This is just an example of how in real life no event occurs singly but in the context of may other events. It is in this sense that I mean that information arrives in a shape of a fractal. The main feature of a fractal is that distinct patterns are repeated, even though never precisely, on many levels, regardless of how far one cares to zoom in or out. If the 'main event' is a completed pattern on the level of a certain scale, then many smaller similar patterns/events are formed before the larger one and in effect comprise the larger one.

        I apply the same general idea to the realm of Quantum, following the clue that the output of cellular automata (CA) often has many features of a fractal. And so I visualize spacetime emerging as a result of CA-like processes that generate 'events'. In the terms of a 'participatory scheme' it means that such a process takes some 'bits' of energy as input and outputs some other 'bits' or a 'bit' in turn (this is my version of the CA of which Prof. D'Ariano speaks in his essay). To this general setup I apply the central theme of SR which implies that each process 'sees' its own order of the preceding events, each from its own reference frame (even though the definition of RF is somewhat different here). If the relevant events generating those input bits for the processes in question are represented as a set, then this set is ordered differently by each process that draws its input from this set. I thought this offered a good visualization of how the 'beads' of events are 'weaved' with the specific to each process 'thread of causality' into the fabric of spacetime underlying reality.

        .

        Re: Russian humor, the word is 'cutlet' (as in "a patty of chopped meat or fish, usually coated with bread crumbs and fried"), which I thought was better replaced with more familiar 'hamburger'.

        Thanks again for your sincere feedback. I value it a lot :)

        Thank you Lorraine for taking time to read and comment on my essay :)

        You wrote: "In your final discussion where you talk about "each participating event, or a process", are you talking about subjects? If not, if reality is just "a process of active information exchange", what is it that differentiates anything so that it can be described as an event or a process?"

        Well, in my view a process generates an event; and an event is the act of putting out a transformed form of energy. And I am not talking about subjects, even though it was Life that I said could be defined as "a process of active information exchange between the living things and their environment". Clearly 'dead matter' also exchanges information with its environment, in a far simpler form than life processes.

        .

        I wanted to convey the idea of reality as emerging as a result of underlying processes that together shape the dynamic structure of space-time. In essence, this view is similar to Margriet Anne O'Regan's who finds information's ontological identity in pure geometry of all things in existence. In our current understanding of 'things' everything is ultimately 'made of' the underlying quantum processes. Here information is a process that gives 'space' its dynamic shape, thus revealing the geometry of 'things in it'. I believe this is what ancients also meant, within their own framework, in the quote I used for the title.

        .

        Re: Wheeler's participatory anthropic principle, according to the essay by 3 authors Singleton, Vagenas, and Zhu, he came up with it and coined the phrase "it from bit" back in the 1950s and not the late 1980s, as some people assumed by the publishing date of the most commonly available reference. This makes more sense, as in the 1950s these ideas not only looked more fresh and intriguing, but also fit the context of the state of knowledge of the time. Nowadays, while the question of information is still actual, so far I have not seen one essay that took Wheeler's PAP seriously.

        ..Which unfortunately does not mean that anthropocentrism is no longer ingrained in our approach to science. Thus regarding my allusions that there are other types of energy/information waiting to be discovered, I may as well confess now that when I decided to participate in this contest, my initial intent was to challenge the current assumption that we already know all energies/forces shaping the reality and now only pursue a deeper understanding of them.

        I had a good example of such an ignored and => unexplored type of energy in mind, but then decided against bringing it up, mainly due to the controversy surrounding the phenomenon (even though the reality of it can be easily assessed by anyone interested -- I know of at least 2 tests one can perform to establish this fact). By extension, this would suggest that, in addition, there may be yet other types of energy/information still unexplored and they may be the way out of the current impasse physics reached with QM. However, the search for these 'other interactions' that could be detected with either improved or entirely different technology is precluded as unscientific by the constrains of the Copenhagen interpretation.

        Later I may still bring up that missing context, without which, admittedly, my allusions that there must be other types of information 'out there' seems unjustified. However, I would also like to point out that the main difficulty surrounding the phenomenon lies in the fact that, while being of physical nature (as in clearly affecting biological systems), it does not fit into any of our current scientific schemes. It is on these grounds --i.e. that we have no clue how it works-- that the reality of it is denied (!) This is the manifestation of the anthropocentric principle at its worst, for it demands in effect that the universe must match our established schemes about it and not the other way around.

        .

        You mentioned spelling glitches (thank you :). I obviously don't know what you refer to, for otherwise I'd fix them. I generally rely on Word, which of course is of no help when I use totally wrong words lol. It is true that English is not my native tongue and my 'print accent' usually shows in wrong placement of articles and odd use of prepositions. Perhaps you recall what exactly those glitches were? I'd really, really appreciate it. I hope there was more to it than just 'spacetime' -? I am aware that there is another spelling but prefer this one, anticipating that it might be the 'right' one in not so distant future :)

        Thank you again for your positive comments and your feedback on my essay!

        Thanks Marina for your reply to my comments/question.

        Your English expression and fluency is excellent, in many ways better than mine. But as you have requested it, and at the risk of my being seen as a nitpicker, here are the spelling glitches I noticed:

        "the living lings and their environment" page 1

        "In his thesis Wheel conjectured" page 3

        "maybe his main intension was to provoke" page 3

        "until the observer takes a peak" page 7

        "a subset of what is to be head out there" page 7

        "in terns of another process" page 8

        Cheers,

        Lorraine

        Dear Madam,

        Your essay is very interesting and different from most essays, though have many similarities with our essay. Hence kindly bear with our lengthy comment.

        The last paragraph of your first part is interesting reading, but you left out the conclusions. We perceive the result of measurement by our sense organs. Where the instrument is faulty, the readings will also be faulty. Reality must be invariant under similar conditions at all times. The validity of a physical statement is judged by its correspondence to reality. In a mirage, what one sees is a visual misrepresentation caused by the differential air density due to temperature gradient. All invariant information consistent with physical laws, i.e. effect of distance, angle, temperature, etc, is real. Since the perception of mirage is not invariant from different distances, it is not real. Similarly, a jaundiced person sees everything yellow. Since it is known to be caused by a disease (as is color blindness), the vision is not real.

        You begin the second chapter by discussing reductionism, which is one of the causes of the present maladies of physics. There is an anecdote of six blind men who went to 'see' an elephant. They touched one part of it and described the elephant by that perception. All of them are right in their description. But, even if you combine all their versions, you cannot make any meaning out of it unless you have seen an elephant earlier to put these in the right sequence - or like a jigsaw puzzle you put the right pieces in the right place accidentally. The incremental branching out of physics must stop and all theories should be rewritten by compiling all known facts in the right order.

        A priori knowledge is a necessary condition for perception. In the perception "this (object - bit) is like that (the concept - it)", one can describe "that" only if one has perceived it earlier. Perception requires prior measurement of multiple aspects or fields and storing the result of measurement in a centralized system (memory) to be retrieved when needed. To understand a certain aspect, we just refer to the data bank and see whether it matches with any of the previous readings or not. We cannot even imagine something that we have either not perceived earlier or inferred from such perception. The problem arises when we try to imagine something not conforming to physical rules. We have seen rabbits and we have seen horns. But horns of rabbits are possible only in dreams and not in physics. This implies limited knowledge or knowledge boundary.

        Participatory universe in the right context is not a bad idea. Everything in the universe is interconnected and interdependent. You cannot take out or isolate anything. The state of knowledge varies in each case. The plants have only one sense organ - tactile perception, which is the fundamental perception that covers other perceptions. The virus, bacteria, etc have two sense organs - tactile and olfactory. The insects have these two and in addition have ocular perception. The animals and birds have deficiency in one of the sense organs. Only humans have well developed five sense organs.

        In the mechanism of perception, each sense organ perceives different kind of impulses related to the fundamental forces of Nature. Eyes see by comparing the electromagnetic field set up by the object with that of the electrons in our cornea, which is the unit. Thus, we cannot see in total darkness because there is nothing comparable to this unit. Tongue perceives when the object dissolves in the mouth, which is macro equivalent of the weak nuclear interaction. Nose perceives when the finer parts of an object are brought in close contact with the smell buds, which is macro equivalent of the strong nuclear interaction. Skin perceives when there is motion that is macro equivalent of the gravitational interaction. Individually the perception has no meaning. They become information and acquire meaning only when they are pooled in our memory. In the lower animals, all the sense organs are not fully developed. Hence their capacity to function in tandem is limited. Thus, they only respond to situations based on memory. In human beings, the sense organs are fully developed. Hence they not only respond to situations, but also plan future strategies. This is the difference between them.

        In page 6, you have said that "There are no things in Quantum and no boundaries separating any two different environments. Instead the spacetime is infused with various fields that tend to taper off gradually making Quantum It appear rather fuzzy". A medium or a field is a substance or material which carries the wave. It is a region of space characterized by a physical property having a determinable value at every point in the region. This means that if we put something appropriate in a field, we can then notice "something else" out of that field, which makes the body interact with other objects put in that field in some specific ways, that can be measured or calculated. This "something else" is a type of force. Depending upon the nature of that force, scientists categorize the field as gravity field, electric field, magnetic field, electromagnetic field, etc. The laws of modern physics suggest that fields represent more than the possibility of the forces being observed. They can also transmit energy and momentum. Light wave is a phenomenon that is completely defined by fields. Thus, if the field theory is correct, the quantum world is not fuzzy. But our description is fuzzy. We can precisely describe the quantum particles. But we err in the interpretation of the mass energy equivalence equation.

        The left hand side of any equation or inequality is characterized by free will, as we are free to chose or change the parameters. The right hand side is characterized by determinism, as the results are deterministic - otherwise there would be no theory. The equality sign characterizes special conditions to be observed in each case. Unless these conditions are met (like a certain temperature threshold in chemical reactions), no interaction takes place. Alternatively, it shows the variation parameters like those in the mass energy equivalence equation. When we say e = mc^2, it does not show convertibility of mass into energy and vice versa, because energy and mass have opposite characteristics and the other term is a constant of proportionality. Both mass and energy are inseparable complements. There is nothing like bare mass or bare charge. The equation actually says: a certain amount of energy in an isolated system can spread out mass over a field with area equal to c^2 and no more. When we mix up mass and energy by factoring in the ratio of c^2, we land in problem. Thus, "let us try and keep flies separate from hamburgers".

          Hello Basudeba and Mishra!

          I assume there are two of you, sine you always refer to your essay as 'our' :) Thank you for taking time to read and comment on my essay. You touch on many important points, out of which I am in the mood for answering these:

          You speak of 'perception' as requiring a prior knowledge. Yours is different definition from mine, which is simply the act of.. well, perceiving something, like say, seeing an object, registering its color and shape, etc. For example, I happen to remember myself since just a few months of age, and I remember very well my thought processes and even the shocking realization that started it all; and that was my awareness of myself as a separate entity from the rest of the world. And so I can assure you that even without language and the labels of words we can perceive the reality and come up with certain understanding.

          I'll tell you about the door in my room. My crib was facing the window on the other side of the room and a meter on the left from it was the door. I did not know that was a 'door', so in this sense you're right about the need of a prior knowledge. This magical, in my mind, rectangle held tremendous fascination for me. It was far more interesting than the window, into which, since I could not move yet, I could not look. But the door! While always retaining its rectangular shape, it changed colors during the day and sometimes almost disappeared, blending with the surrounding wall. It was the most beautiful and alluring when it was dark, for then, suddenly, a flood of warm golden light would suddenly pour out of it. The most mysterious aspect of that rectangle was that people appeared and disappeared in it. I cannot describe how fascinated I was by that rectangle!

          It was many years later that my knowledge of the 'door' formed, and that included passing through it countless times and, twice, slamming it on my finger. Ouch! I remembered that lesson so well that even now, never-ever, put my hand on the door frame (even when the door itself is taken off the hinges lol -- habit rules).

          And so regarding 'perception', I obviously have a different definition from yours. I'm not saying that mine is better or more valid -- only that the knowledge of the meaning of this word was formed in my mind by my own experiences.

          Then you go on about the 5 senses. I apologize but you are obviously draw your understanding of this topic from the ideas that originated in antiquity and had not changed until the end of the 19th C. Today we know that, say, bats use echolocation for 'vision' (in addition to seeing light like we do). How would you characterize this sense among the 5? Or take the sense of electromagnetic fields used by some marsupials and fish? Into what category would you place that?

          Or let's take dogs, who rely on their sense of smell the most. Do you know that a dog actually forms a map in its head of the surrounding area, about a mile-radius. This map is formed by the streams and currents of smells a dog 'sees' in the air. This undulating map tells it what's going on around. Clearly, this goes beyond our understanding of the 'sense of smell'.

          Then you state that plants have only tactile sense. May I refer you to a popular science book, recently authored by a PhD in biology, titled 'What a Plant Knows'. I should have included it as a reference in my essay, but alas had no time for references. But in this very interesting book you may find out that plants have specialized cells to perceive either light or darkness, distinguish some colors and can 'smell' the air (among many other things). Thus they know when their kind is being damaged nearby and emit certain chemicals that attract predators for the bugs that attack their neighbors.

          So, you see, perception --in my view-- includes various types of information and processing of this information (ex. how a dog forms a map of the surrounding area entirely from smells).

          Regarding my essay, the point that got lost in all that fun was that reality emerges in the dynamic structure of space (or spacetime, as time is emergent property of this primordial substrate -- I use 'space' instead so that the full implications are not obscured by the familiarity of the more prevalent today notion). In this concept --i.e. the dynamic structure of space-- dynamics = energy and structure = information. The organization, or the structure, emerges in the result of the underlying quantum processes driven by a few simple principles. In this sense, everything is made out of 'space stuff' (which itself is a dynamic, vibrating structure). To appreciate how 'matter' may emerge from harmonic oscillations within the vibrating primordial substrate you may want to check out the essay by Carolyn Devereux.
