Astronomer Foschini,

This is an exquisitely beautiful essay to read. You have done for English literature what your countryman Pavarotti did for opera.

    Hello, dear Luigi!

    Many thanks for a good essay that makes a look at the material world more widely and gives direction to research the farthest depths of meaning. You are right: «... it is now clear that the knowledge of the material aspect only is not sufficient to understand the problem of information.» «Grasp» nature of the information and «grasp» the structure of the world begins with a new interpretation and understanding of the Cartesian «Cogito, ergo sum», Kant's ideas about the concepts-figure synthesis, compression, and the restructuring of the entire information accumulated by mankind in all floors being. Good luck in the contest! Sincerely, Vladimir.

      Luigi, you have found a very different take on this subject by considering the importance of language and how it relates to reality through information, especially in the quantum context. I think you have raised some good points worth thinking about. Good luck.

        Dear Sir,

        Your essay is a beautiful analysis on information and its relation to the physical world from the true perspective ending with an explanation of the poser presented in the beginning. It appeared to us as the twin of our essay "Information hides in the glare of Reality" published on May 31, though we approached the subject from a different perspective. Our essay complements your essay in many ways.

        Many of the points raised by you have been discussed in the first chapter of an ancient treatise on Sanskrit grammar called Mahabhashya written more than 2000 years ago. All observables are called 'padaarth' in Sanskrit, which means a word (language) signifying a concept (pada) about some object (arth) or as you say "there is an information encoded and stored in natural elementary structures at the root of all". Another ancient work Vakyapadiya, which gave rise to the study of linguistics, elaborates this concept further. You have also quoted Ferdinand de Saussure to convey the same meaning: what is natural to mankind is not the faculty of speech, but the ability of constructing a language, i.e. a system of distinct signs corresponding to distinct ideas. The binary or yes-no format is about isomorphism that asserts whether the object matches the concept or not, which is the information received by the conscious observer.

        But mathematics cannot always express the isomorphism in its totality. It explains only "how much" one quantity accumulates or reduces in an interaction involving similar or partly similar quantities and not "what", "why", "when", "where", or "with whom" about the objects involved in such interactions. These are the subject matters of physics. Mathematics is an expression of Nature, not its sole language. Though observer has a central role in Quantum theories, its true nature and mechanism has eluded the scientists. There cannot be an equation to describe the observer, the glory of the rising sun, the grandeur of the towering mountain, the numbing expanse of the night sky, the enchanting fragrance of the wild flower or the endearing smile on the lips of the beloved. It is not the same as any physical or chemical reaction or curvature of lips.

        The importance of initial conditions cannot be denied. But it does not evolve as an isolated system. The chains of other influences that lead the "the flap of a butterfly's wings in Brazil" to "set off a tornado in Texas" are as important. These influences introduce the element of uncertainty in the projection of initial conditions. The object evolves in time independent of observation, but it makes meaning only when it is so cognized. The detailed mechanism of perception including invariance has been discussed in our essay.

        As you have pointed out, the findings of Rawlinson that if the first and last letters are in the right position, the internal order of the letters does not matter (for example, "to raed is good for hatelh"), applies to a Latin-based tongues, while for other languages with different symbols and grammar, it is necessary to look for other methods. However, "the material support is of little importance" has to be treated carefully. When we perceive something for the first time, our memory only registers it. Next if we perceive something similar, we cognize it as the object we had perceived earlier. If we had heard a word (name) describing the concept generated out of such perception, we use that word. Alternatively, we may conjoin some other word like children do very often to describe something. It is true that the word does not signify the object, but signifies the concept attached to the object. However, the memory will not function without any external impulse directly or indirectly linked to the concept.

        Animals also have their language, though it is not as developed as human language. As long as they communicate and understand these signs linking the concept to the objects, it must be treated as a language - however primitive. These are parts of Natural language. An ancient work by Bharata divides language into four categories: 1) purely scientific language that builds on the matching process of physical evolution and acoustic evolution, 2) human language based on strict principles of grammar, 3) human language based in general, but loose principles of grammar, and 4) Language of other animals. It is the third category that is used as a signifier.

        But you should not confuse between the abstractions of language with the abstraction in mathematical physics. Abstractions of language refers to abstract ideas depicting a mental state that cannot be physically symbolized (like the feelings of love, romance, etc as different from hugging and kissing), expressed in human language in a skillful manner (such as lyrical rhythm) to keep the mind focused on the subject or feeling. The abstraction of mathematical physics comes from the dimensional differences of mathematical structures and physical structures.

        The graph may represent space, but it is not space itself. The drawings of a circle, a square, a vector or any other physical representation, are similar abstractions. The circle represents only a two dimensional cross section of a three dimensional sphere. The square represents a surface of a cube. Without the cube or similar structure (including the paper), it has no physical existence. An ellipse may represent an orbit, but it is not the dynamical orbit itself. The vector is a fixed representation of velocity; it is not the dynamical velocity itself, and so on. The so-called simplification or scaling up or down of the drawing does not make it abstract. The basic abstraction is due to the fact that the mathematics that is applied to solve physical problems actually applies to the two dimensional diagram, and not to the three dimensional space. The numbers are assigned to points on the piece of paper or in the Cartesian graph, and not to points in space. If one assigns a number to a point in space, what one really means is that it is at a certain distance from an arbitrarily chosen origin. Thus, by assigning a number to a point in space, what one really does is assign an origin, which is another point in space leading to a contradiction. The point in space can exist by itself as the equilibrium position of various forces. But a point on a paper exists only with reference to the arbitrarily assigned origin. If additional force is applied, the locus of the point in space resolves into two equal but oppositely directed field lines. But the locus of a point on a graph is always unidirectional and depicts distance - linear or non-linear, but not force. Thus, a physical structure is different from its mathematical representation.

          Thank you very much for your comment. It is really interesting to read about ancient Indian linguistic books: do you know if there are current translations in English? I would be interested in reading those ancient treatises.

          I have read your essay and found it very interesting. I like your definition that "Pictures are the inertia of motion generated in memory (thought) after a fresh impulse, linking related past experiences".

          In your essay, I understand that you linked the invariance with the generation of a physical concept. You wrote that "Something makes meaning only if the description remains invariant under multiple perceptions or measurements under similar conditions through a proper measurement system". However, please note that the invariance invoked by Wigner - and cited in my work - is something that was necessary in the past to create classical physics and it referred to laws, rather than concepts. Anway, the quantum mechanics, general relativity, and quantum gravity, are today showing that Wigner's invariance is no more appropriate.

          Moreover, in your essay, you do not take into account the role of human beings in defining the language. In the latest pages of your essay, I read about some strong link between the word and the meaning, although sometimes you refer to a "fixed meaning", while some other times you wrote about the possibility of different meaning in different context. You made examples with macroscopic physical objects, where the translation in different tongues is easy: surely, it is easy to translate the concept of mother or father, since we all have one of them. It is much more difficult to translate an abstract or imaginative concept with no macroscopic physical counterpart. Think, for example, to jokes of words: you completely lose the joke when translating from one tongue to another.

          You also wrote in your above comment:

          "All observables are called 'padaarth' in Sanskrit, which means a word (language) signifying a concept (pada) about some object (arth) or as you say "there is an information encoded and stored in natural elementary structures at the root of all"."

          Well, I was citing Wheeler and to refute his statement. I think that the meaning (the it) is created by human beings. Nothing is stored or encoded in the nature (the bit). My essay is dedicated to show this.

          Thank you again for your interest. Best regards.

          Dear Luigi

          I just read your nice and interesting essay. I just wanted to let you know that I share your view. Karl Popper reminded us that many times problems between man have their source on how we express our ideas. I do agree with you that the "it from bit" issue can be a problem of linguistics more than any other thing.

          You: If physics is what we can say about the nature, as written by Bohr, then to wonder what happens by changing the parameters derived from experiments and observations is no more physics, but science fiction (or even pataphysics).

          I agree with this too. By varying parameters to fit data we are not gaining knowledge of reality. In my work I make emphasis on these points. I'll be glad if you could take a look at it and leave some comments. There I give a nice example of how to get out of the present conundrum in physics, this has to do with the conception of space (or vacuum).

          Best Regards

          Israel

            Thank you for your kind email. I have read your essay, and I am going to comment on your page. Thanks again.

            Dear Luigi,

            I fully agree that the coupling between the mathematical symbol and physical quantities is precisely where scientific creativity is at work. The signs, and their correlations (one can have in mind Mermin's view of quantum mechanics) correspond to the language, and the latter is a property of the man. As Wigner told us, it is a bit miraculous that mathematics and physics fit (at least to some extend). I agree with you that "it from bit" has to do with creativity, and not only in the quantum world.

            In my essay, I argue that the " it from qubit" is contextual.

            Best wishes,

            Michel

              Thank you, Michel. I have read your essay and found it interesting. Good luck for the competition!

              Luigi,

              If given the time and the wits to evaluate over 120 more entries, I have a month to try. My seemingly whimsical title, "It's good to be the king," is serious about our subject.

              Jim

              Hello Luigi,

              An interesting read and very relevant. I thought the cat and dog comprehension was a great way to exemplify your point.

              I too agree that multiverse isn't as good an explanation as chance by quantum fluctuation.

              Please take a look at my essay if you have the time.

              All the best for the contest,

              Antony

                Dear Luigi,

                You have presented nice work, I am enjoyed with your judgments and large informativeness of your essay. I have however my approach to Wheeler's statement and to topic of theme. Particularly, I am thinking it is obviously incorrect to examine next questions before of solution previous ones. I mean the ,,quantum facts,, that not yet explained completely (despite we have its qualitatively description), and we hurry for talking about quantized bits already! (This remark not connected with your work, I am just offended by such approaches)

                Please to open my work Essay in your good time and just see is it interesting for you and can we have common points? Let my say once more - your essay is very attractive (I need to read it more carefully)

                Sincerely,

                George

                  Thank you, Antony. Your essay is interesting too! Good luck for the competition!

                  Dear George,

                  thank you for your comment. I too have appreciated your essay. I understand your analysis of the current crisis in science (although it is a bit harsh...) and, perhaps, you might be interested in reading a recent post I have written in my blog on a similar topic.

                  There are in your essay many common points with mine, as the need to recall to a link with reality. Although, while you wrote:

                  [...] physicists must start from analyzing the physical essence of phenomenon before application of mathematics [p. 9]...

                  on the other hand, I do think that mathematics and tongue are the primary tools to understand phenomena. I don't think it was possible to analyze any physical phenomenon without operating on any type of sign. If you want to study anything, you have to define at least the names of what you want to study.

                  Good luck for the competition!

                  Dear Luigi -

                  You frame information in terms of evolution and language, taking a biological perspective which I find very interesting.

                  You also arrive at what I call a Species Cosmos: 'It is the human being that, by assigning a meaning and creating a tongue with the signs so obtained, creates the it from bit.'

                  I believe you draw a parallel between a multiverse and the processes of the human mind. In my essay, I take up the same line, but in a different way: I express the relationship as one of Correlation, and deduce the nature of the participatory Cosmos from that.

                  As I say, a most interesting perspective - and I would love to hear what you think of my view.

                  All the best,

                  John
