Dear Philip,

Thank you for reading and commenting my essay.

Your question "Symmetry of space and time means that the laws of physics are unchanging over space and time. If that were not the case it would be hard to do science. Does this mean that symmetry must be fundamental?聽" is linked to the approach you have in your essay.

"symmetry is agebraic" you say, so it is part of a "language" that is an intermediate between thinking and reality (both emerging phenomena). In my approach fine-tuning is an essential result of the Reality Loop the agent is part of. (if its was not fine-tuned the agent would be a different agent in a different reality loop. One of the languages agents are using to explain this fine-tuned reality is emerging algebra (symmetry).

You argue "I expect to find this symmetry in a pre-geometric meta-law that transcends spacetime,taking a purely algebraic form, only beyond that point will it be emergent, rising from immutable relationships between systems of information." Indeed in this approach symmetry transcends space-time because space and time are (dimensional) restrictions (emerging from total simultaneity), and algebra/symmetry/thinking are not limited by these restrictions because they are the "cause" through consciousness of reality. The what you are calling "immutable relationships between systems of information" is maybe too strictly bound to our emerging reality. My approach places the "rising" outside our reality, so even more foundational.

"If those leaders say that symmetry is unimportant because it is emergent or that geometry is more fundamental than algebra, other possibilities may be neglected."

Fully agreed, every emerging phenomenon is essential in a specific reality. Geometry is a description methodology, to be compared to filling in data in a computer, it is the software (thinking) that is concluding.

Best regards Philip nd good luck in the contest.

    Thanks for the interesting answer and good luck in the contest.

    Biology doesn't demand exact laws

    Firstly, I agree that recursion is important in physics. But inexactness has a role to play in the natural world as well. To quote from my own essay (in note 4): "In the context of technology, high precision may sometimes be necessary to achieve particular aims, necessitating the use of special methodologies. Biological systems can survive without such high precision, but a degree of constraint is necessary nevertheless. While precision has its value in the biological context, high levels of precision may not be necessary for survival.". However, mathematical properties may emerge in the limit through recursion, and the ones that prevail are the ones that are significant from the viewpoint of 'good design', since favourable consequences make it more possible for nature to loop back (consider for example the way languages tend to use words only to the degree that they have a role to play in the activities of a community). Investigation of the reciprocality between maths and biology is the main aim of the IBIOSA project (see http://inbiosa.eu/).

      Dear Philip,

      One again that time of year to bug you:) If you had seen my essay you can strike what I am about to say. Otherwise I am going to save you the trouble right here. based on the conversation you had with Dickau. I say

      "The system can use both Real and Integer numbers, and in both systems you always get finite answer no matter how high your energy goes as when using Real mainly because the energy represented by line length summed up according to weights dictated by the interaction makes the short segments naturally lose their effect in long range interactions and the energies never blow up, even in short range.

      As can be seen in the simulation of the electron mass (actually mp/me ratio) simulation the system is scale invariant, that is multiply the D0/D1 by any number the linearity makes the system scale invariant and you basically you get the same curves i.e. if you zoom in(or out) you get exactly the same curves. That is, when you are doing the electromagnetic interaction i.e. line crossing you always get the proton/electron ratio. because of the two special location which could be some phase change "

      second

      "Now suppose I ask you to tell me what will happen to some "object", but I don't tell you anything about it (how fundamental can you get) !! like what mass it has or what it will do if another thing is present. Ok, I'll give it a try. First I will say I will "invent a coordinate and since I don't know where it exists I will restrict it to be in some range and eventually make that range variable. This lonely thing would have a meaningless existence. i.e. it needs a partner. If we add another one next to it with similar setup and at some distance that can also be varied. Now, we can calculate all relative information just like our original idea in the essay.

      Kaboom! both situations reached the same conclusion with generalization leading to all of physics ( at least the important) QM, QFT, Gravity like shown. In one instance we acted like GOD and decided to design a dynamic universe, in the other we are ignorant humans but figured out how things should work, and both match and are the FUNDAMENTAL building block. "

      Thank you in all cases. and just in case

        Sorry, FQXI's editor ate the formatting and some letters:(

        Dear Philip Gibbs

        Just letting you know that I am making a start on reading of your essay, and hope that you might also take a glance over mine please? I look forward to the sharing of thoughtful opinion. Congratulations on your essay rating as it stands, and best of luck for the contest conclusion.

        My essay is titled

        "Darwinian Universal Fundamental Origin". It stands as a novel test for whether a natural organisational principle can serve a rationale, for emergence of complex systems of physics and cosmology. I will be interested to have my effort judged for prospect and for novely.

        Thank you & kind regards

        Steven Andresen

        Thank you Philip,

        I am not a schooled mathematicien like you are.

        So I wonder if the "model" I approached might be valuable.

        It is of course only one of the many that exist, but the human intelligence

        is at this joint of time just a like a baby, we are all struggling with finding the

        foundational essence of our reality, we see the rattle above our craddle, we reach out but still cannot touch it....(this contest is an exellent example of this reaching out...)

        I rated you already on january 13, and hope that you will find my approach also good enough for a valuation.

        thank you

        Wilhelmus

        Philip,

        Seems to be sparse reviewing and rating in this essay contest so far. I am revisiting those I have reviewed and see if I have scored them before the deadline approaches. I find that I did on 1/23.

        Luck in the contest.

        Dear Philipp,

        very nice and thought-inspiring essay. I was wondering whether by arguing stories are fundamental you believe that information is fundamental. As I'm arguing in my essay information usually has some perspectival elements to it and - as far as we now - needs a medium or information carrier. My stance would be that this medium is more fundamental at least than the information dependent on perspective. You seem to argue that such a medium is equivalent to „nothing" and actually I also consider this possibility. I would argue though that this would be only correct if „physically possible" would be equivalent to „logically possible". While this might be the case I believe we can`t take this for granted.

        Anyway, a very nice read! Heinrich

          quote

          Every possibility is assigned a probability. These are derived from the squared norm of a component

          in a wave function. Observables become operators, states become vectors, sets become functions,

          objects become morphisms. In physics we call this process "quantisation." It is closely related to the

          mathematical notions of exponentiation, abstraction and categorification. Even probabilities

          themselves may be uncertain, so they too are given a probability distribution. The process can be

          repeated to give us iterated quantisation, higher abstractions and n-categories. To understand the

          origins of physics we must define this recursion more precisely in algebraic terms and see how the

          physics of space, time and particles can emerge from it with specific features of our universe

          understood as processes of information collection. The fundamental laws of the universe are then

          uniquely determined by invariance under quantisation [4]

          end of quote

          Very interesting point. What I tried to do was to find , using Klauders enhanced quantization, a way to bound the behavior of classical physics, via a quantum analogue, as to the emergence of of the cosmological constant.

          My essay is of December 21st. As a favor to me, could you critique my essay as given in FQXI, in terms of your above mentioned procedure?

          Thanks

          Andrew

            Dear Philip,

            some water into the wine of positive comments. In the following quote: "I expect to find this symmetry in a pre-geometric meta-law that transcends spacetime,taking a purely algebraic form, only beyond that point will it be emergent, rising from immutable relationships between systems of information" there feature at least six to eight terms that either are entirely undefined (e.g. pre-geometric meta-law) or at least have multiple, varied and even opposing meanings. I have roughly 'calculated' the number of possible meanings of just this sentence to be of the order of millions. The number of possible meanings of your essay is of course magnitudes bigger.

            So, your essay appears to me much like a box full up with words marketed as a novel.

            Hence your conclusion: "From there [the above] our understanding returns full circle to the nature of our experience and our personal life stories" reads something like: believe me that no less than six angles can dance on the top of a pin.

            Heinrich

              Many theorists agree that space-time geometry could be emerge from something else. That structure is often therefore described as "pregeometric." I.e. It is a common generic term in physics used to describe any hypothetical theory in which space and time is emergent. Wikipedia is always a good place to turn to when you don't understand a term and in this case it gives several good examples of mainstream pregeometric theories http://en.wikipedia.org/wiki/Pregeometry_(physics)

              "The meta-laws" here just mean the theory of this pregeometry. They are meta-laws in the sense that the laws of physics we know are just one possibility of what could emerge from the meta-laws. They exist at a deeper level. I am talking here about theory whose exact form is unknown so in that sense it does have multiple meaning, but what I am saying applies generically to whatever those meta-laws are. Again the term "meta-laws" is in common use although it is less common than "pregeometry"

              I think the meaning of my statement that it takes a purely algebraic form should be clear enough. If it is pregeometric is should not be a theory of geometry so it could be algebraic or combinatorial or something else. Quantum mechanics is very much algebraic so once the geometry has been transcended it seems reasonable to expect that what underlies the theory from which it emerges will be algebraic.

              I don't think "relationships between systems of information" is very ambiguous even though I do not describe those systems in general. Also I think the words "symmetry" and "immutable" are unambiguous.

              Possibly the problem here is not that this can mean different things, but rather that I am referring to generic concepts where the detailed implementation of the ideas is not yet worked out. I don't see how this can be avoided given the essay topic which forces us to consider questions of what fundamental means when we don't yet have a complete fundamental theory of physics to work from. I am pleased that others seem to have understood some of what I say in that context and sorry that you have not.

              Thanks for you comment. I already read your essay and made one comment, but hopefully I will find time to give it another read in the context of your comment and perhaps say more.

              Numbers are always used to count things or measure them, yet in mathematics we can study the properties of numbers in their own right without reference to what is being counted or measured. This is abstraction.

              Information also needs a carrier and it needs to be about something, but it has its own generic properties independently of these. The same information can be transmitted by radio waves or stored in a disk. We don't have to take that into account if we are computing the entropy of a bit stream.

              I am not saying that you are wrong about the medium being more fundamental. I am just saying that because of abstraction it does not have to be.

              Another interesting question is whether information can have meaning without some way of interpreting it. A compressed bitstream appears random and is impossible to extract meaning from, but uncompressed data may eb able to convey a message without an interpreter. Remember the film "Contact" where they picked up an alien communication that started with prime numbers and then moved on to other forms of information that could be understood. If the information was about pure mathematics that could even work across universes if there were some way of transferring bit streams between them. The key to making sense is to use redundancy and universal concepts like prime numbers that inevitably arise in the mind of any mathematician no matter what form of being they are.

              Thanks for your comment. i will have a look at your essay.

              Dear Philip,

              You give very deep ontological ideas in the spirit of Cartesian doubt. I believe that this is the right way to overcome the crisis of understanding in the foundations of knowledge. I invite you to see my ideas of ontological с, where the "logos" - "metalaw" creates from the matter another alternative model of Ideality.

              All the best,

              Vladimir

              Hi Philip,

              Thank you very much for your comment. I agree with Tegmark that All mathematical structures (circles, triangles ....etc) exist in what is dubbed as PLATONIC. However I think we must find the *correct structure* that represents our reality with all of its details (like I have proposed) before dabbling in Multiverse types( his four levels) which are connected to premature interpretation and cosmology (which should be based on the newly found theory). My idea leads to possible proof that reality is a mathematical structure and reality is a proof that mathematical structures are Platonic i.e. they exist(actually the only thing that exist).

              As for the cellular automata, as you know many have been proposed but no direct results that connect to physics have been shown. Some of Wolfram's NKS rules seem to come close to some aspects in my idea but I have not investigated fully. Also 't Hooft idea for example does not use CA to derive any physics as such only to use it as general argument for the interpretation part.

              My system is not strictly an automata only some resemblance because I started as a design of a simple mathematical structure which is based on relations between numbers (two of them interpreted as lines). As I added some relations which lead to the concept of interaction, only then the system seem to resemble a CA, however with one major difference, that is the cells could be faraway anywhere. And so the big result in my system is that QM arises precisely because of these non local relations, so that is why EPR in my idea is so trivial and automatic(see spin). That is Entanglement (in my theory the relations between all point in space which themselves were created imperatively by the structure) is the basis of QM and hence reality. Of course, all these nonlocal effects also lead to local effects( as in standard theory) which I have not shown explicitly, also particles cannot have higher speed than light. You could see modern theories (entanglement ideas) are like rats in a maze, they can smell the cheese and get close to it but haven't fount the right road. I think they will reach the same conclusions as mine however longer road they have chosen.

              you can zip through the programs by removing two zeros from Kj variable which is the number of random throws, you will get less accuracy but I think you will get the idea.

              You can also see that all the programs pretty much they use the same logic.

              Dear Philip,

              thanks for answering a not so positive comment! The fact that a term is accepted in, say, physics does not imply that it has meaning. The 'multiverse' is such an example, because it is not hypothetical but merely speculative. My point was to say that a compound of meaning-less or very vague notions is not well suited to argue anything.

              In addition, by the very well defined meaning of the word 'transcendence' one points to a domain about the form and operations of which nothing can be known in principle. Your 'transcendence', however, mediates between two domains of which you claim to have or hope to gain knowledge. So, the use of 'transcendence' WITHIN physics is an oxymoron.

              Heinrich

              Something being 'speculative' doesn't mean that is has no meaning: one may for example speculate that someone is late because he has been held up by traffic, and it is perfectly clear what the meaning is. In regard to terms such as emergent or multiverse one has to turn to the literature to discover what precise meanings have been assigned to the term concerned, it is not a matter of there being an absolute meaning as there is for example in the case of multiplication of integers.
