8:57 I am trying to find a polite way to say this, and I may fail, but here goes: these ideas about computation and physics are upside-down. Just because we can describe the tiny part of the universe we know about as computation (and that includes mathematical models of physical observations of course, but also the process of formally proving theorems about the properties of those models) does not mean that the Universe is fundamentally a computation. It just means that computation is a general characteristic of our models, because they're mathematical, and computation is in a sense the most general mathematics we have. Similarly, when you complain that a physical theory requires an infeasibly large computer to simulate it, that is not a valid objection to the theory. The Universe does not have to contain a machine simulating our models of it for those models to have some validity.

Can physics be rationalized?.....certainly......here's how........Abstract......This work presents a novel geometric interpretation of the fine-structure constant, α = 1/137, as a radiant angle of parallelism between the intrinsic magnetic moment difference vectors P(n+1) - P(n+0 ) = α_a, P(n+0) - (Pn-1) = α_b, and P(n+1) - P(n+0) = α_c and (α_a + α_b + α_c) < π(elliptic), = π(Euclidean), > π(hyperbolic) for fundamental particles, such as electrons(P(n-1)), protons(P(n+1), and neutrinos(P(n+0)) and work includes a calculation to approximate the maximum number of protons and electrons bounded by the outermost surface of our universe, predicted by the truth of the prime number theorem. Let’s use the prime number PNT theorem and let P = 10^800 equal the number of prime numbers in our universe that maps to its maximum number of protons. Then write the theorem Pn/n = 10^800 / log(10^800) ≈ 1,842.06... Next, let’s generate a rational formula for computing the orbit arithmetic ratio proton(P(n)) / electron(n) and cardinality same and #protons = #electrons. The rational science reason why we calculate a proton to electron 'rest mass ratio' ≈ 1836 is because the size of our universe becomes a predictable Gibb’s minimum free energy factor that divides all rest mass points tagged with a 'rest mass ratio' whose value is predicted universally true by application of the Prime Number Theorem. This perspective point projection aims to bridge various fields of study, including quantum mechanics, prime theory, and cosmology. By re-imagining the fine-structure constant in a geometric context we can place a finite field boundary limit on the size(∆X) , half life(∆T), and maximum conserved energy change(∆E) of our universe, proposed a unified model that may best describe the physical nature of the universe that we both imaginary mental and real physical are rationally bound by successor twin prime and successor Gaussian twin prime paired field endpoints......

Interesting Cayley related arithmetic. Define that < and > have numerical value 1/0, <> has value 0/1 and >< has the value 0/0. Numerical addition is defined as mediant addition aka freshman addition to represent the concatenations of the operator language. < >< : <>< 1/0 + 0/0 => 1/1 = 1/0+0/1 = 0/1+1/0 = 0/0 + 1/1 <>< >< : <><>< 1/1+0/0 => 1/2 <><>< ><>> : <><><><>> 1/2+2/1 => 1/4 In certain order the numerator elements of a word combine into a denominator element. The string lengths of the operator language generally follow the Dirichlechts theorem for the case a+2b for coprime fractions a/b. The strings <><> and <><><> with values 0/2 and 0/3 contain substrings <>< and ><>, numerically 1/1 and 1/1. Could this denominator splitting feature of this operator language be used for defining calculus for the peaks and cusps that are currently undefined?

Hello Dr. Wildberger, nice to see you back! I really value your work over the years. I have followed you since the beginning (around 2007 if my memory is exact). I have interacted with you periodically since then. I now think I understand fairly well your approach and philosophy. I have used your material to apply it to my own thinking over now almost 20 years. And I have gotten to pretty exciting results! Basically, things can be said like this: you gave me an assignment, namely, the assignment to understand the continuum. No more, no less! It was in one of your videos. So I proceeded to do just that. And, lo and behold, I got to something! It worked! The result is what Descartes and Leibnitz both called "mathesis universalis". In other words, it is a COMPLETE knowledge paradigm (you can also call it a "representation" paradigm), which is both rational AND complete!! Just what Gödel said it was impossible to achieve!! But I did it. I even used Gödel's own commentaries about his work as a starting point! It lead me to a COMPLETELY RATIONAL understanding of the universe. Even better, I reckon that this new "paradigm", which is really a societal paradigm, will change the world for good, and forever! I even applied it to the drafting of a new "mosaic" law, to rule all societies of the future! But let's come back to mathematics, because the "Archaetype" (this is the word I use for this symbolic/formal representation of reality, which I derived from scratch) is an extremely powerful tool. The "Archaetype" is 2-dimensional, and it is "meta-axiomatic" (does not rely on axioms, but "subsumes and transcends" ALL axiomatic systems). So I am now in the process of applying it to physics, and it works! Basically, the aim is this: to re-present reality symbolically (ie, "mathematically"), using only space and time and nothing else. In other words, the aim is to have matter altogether "emerge" from spacetime geometry. That is it. When doing that, something comes out right away: the need for new symbolic re-presentation, ie new "mathematical tools". In a nutshell, the real continuum is such that it is continuous but everywhere non-differentiable, ie it is "fractal". To model that is very difficult, because, ideally, the usual differential and integral calculus has to be replaced with something else. And this is where your approach comes in. Because I think it is purely a combinatorial problem. In other words, there are certain ways to combine symbols that are still unknown, and which will give us an actually "true" re-presentation of the structure of reality. That is what your work is all about. At this point, I think that what is needed is a re-assessment of everything you have done, in order to condense and refocus your work an the core insights, to extract its "essence". You have spent so much time explaining and explicitating it that the essential message is diluted. Moreover, you have spent so much time refuting the idea of mathematical infinity that you also have acquired some biaises in this regard. One thing that was very interesting is when you started talking about what you called "QIA" (quadratic inverse algebra). But this has to be brought to its logical conclusion. And so far it hasn't. Another connected one is everything concerning dihedrons and connected algebras, together with all your "Chromogeometric" stuff. In fact, all these things should be brought together into a whole to allow for the emergence of a new, purely algebraic, "universal calculus", that will effectively replace what we call "analysis". I don't want to bother you too much, so I will stop here. But I wanted to let you know that there are some people out there, who have followed you for a long time and internalized your teachings to build upon them. And that the fact that you did it on the Internet, as, basically, the first person to do it in mathematics, is very significant! It allows, that you are aware of it or not, the emergence of a new "Copernican" revolution. It's brewing right now. I hope you'll be able to see it!! See you later now! Take care! note: Richard Hamming said very important things that should be built upon!

if you go inifinitely small you end up with zero, right? or is zero smaller than infinitely small? maybe a reason to dump zero as well? I'm still not convinced zero exists. Physicists ask: why is there something rather than nothing. I would answer: because nothing / zero does not/cannot exist. And they have proven that in a way I think. it's called vacuum energy. I wonder: if there was just a tiny little region in all of space, say 1 mm³ where there is really nothing - how could that nothing be characterized? which properties would it have. Similar in mathematics: does zero have any properties that can be connected to a real (physical) object?

the example in the beginning of 2 elementary particles interacting, a proton and an electron, as they move relative to each other, made me realize something important, as the professor intended. they cannot be interacting according to a continuos field , because there would be no way to complete the computation in finite time at each instant, never mind constant motion. there MUST be some underlying computation for the forces which completes in a time independent fashion, no matter how many particles are interacting. i think this is a STRONG argument for the necessity of this rational approach? am i right in thinking this ?

I don't think you're right on this, and I don't think that the picture is correct that either the electron itself should "solve" some kind of equation in order to "know" in which direction it has to move or that some external entity has to solve such equations and to put the electron back on its correct track. The entire question whether the universe performs (infinite or finite) computations is misleading and suggestive.

I was using the terms "solve" and "compute" as metaphors for how the electromagnetic fields and forces are known as real entities to objects that are influenced by them, which must occur if the concept of a field is correct. we are talking about a conditioning of space itself.such conditioning could happen in real time , i guess, if space was quantized into elements which had a kind of memory which stored such values and altered them in real time based on simple rules based on neighbouring elements? i mean it's the problem of action at a distance, raised by Newton that still bedevils all known forces now, which are all of this nature, since the field theories work, but no one knows how ? the fact that quantum mechanical descriptions, relying on simple local matrix transformations, works, seems to point in that direction ? just thinking out loud 😃i'm sure much smarter men than me have puzzled over this one for a long time lol

Pushed to this extreme, that idea self-contradictory, if not absurd. In my opinion (and that became clear to me in quantum theory), we (as humans or as scientists) cannot know how nature really is. The best we can do is to describe the behaviour of (ideally) isolated parts of it, measure its current state (with inherent imprecision) and predict future states (within corresponding limits of precision).

@WK-5775 there has to be "something" that runs the universe. We have an arrow of time, we have a limit of how fast processes can occur (speed of light) - at least when it comes to anything that is related to the propagation of information in one way or another - and there ARE laws that govern everything in nature whatever these laws may actually be. Some physicists theorize that we just live in a universe with these particular laws but there could be other universes with different laws while others think the laws have to be that way (and cannot be different). I think (not know) it's the latter. Anyways, whatever "runs" the universe is bound to its specifications, laws and limits. Hence, a process of infinite precision should be impossible. which in turn means that you cannot go arbitrarily small or continuous. I figure physicists still do not know if space-.time is continuous or quantum. But if it's continuous I would guess it probably does not have substance or physical properties - it's just there, and maybe has to be there for some reason.

@@njwildberger The problem with the "I just observe it" viewpoint is that it's question begging. You had to develop a quasi-finitist intellectual hugbox to divorce yourself of the view that there isn't just a set of natural numbers, even if it's a mental construct that doesn't "fit inside the universe". Your viewpoint on physics/math is also a very specific, historically motivated bias: that math and physics must be essentially just like the computer architecture that humans invented in the 1940s and 1950s. When framed that way, it sounds less probable that the universe's absolute foundations are computational in roughly the same way that computers are. This bias that it must be essentially computational also leads to strange conceptions like a force computer needing to do infinite calculations (or really any calculations) in the "background" somewhere, when really what Occam's razor points to is there not being any "force computer" that computes forces, and the universe just operating without the assistance of explicit computation. It's also not entirely clear what "Occam's razor" should actually do in a lot of cases. Many people would say that your insistence that a square of unit side length's diagonal doesn't have a length (because it's length is an irrational number) is preposterous, and that "Occam's razor" dictates that it does because that's "just what they observe".

In the video, it is stated that the mathematics used to describe physics should be computable, but it is clear that computable here means computable using a Turing machine. There are also analog computers, although they have never been common and are almost forgotten nowadays. The intention with analog computers was to simulate real-world continuous physical processes with other continuous physical processes that were easier to run as part of a computer. These days, there is a lot of attention on the creation of quantum computers, and they may also be used to simulate physical processes that are hard to simulate on a Turing machine.

Actually I don't think of computation as involving a Turing machine, as there is no such thing ("infinite tapes/memory banks" are as much a fiction as are "infinite sets"). I mean computation in the ordinary sense of something that our desktops/laptops can do when they are in arithmetical mode. So it is a bit of an informal term I admit. Not sure that even the computer scientists have worked out what exactly it should consistently mean, as your comment re quantum computers suggests.

The continuous Turing-Tape is an empirical and logical necessity. Before Turing-Head can move EITHER L OR R, we need something to continue BOTH L AND R. The analogical continuum required can be finite ore at most potentially infinite (and coherent with the Halting problem), not any "actual infinity" aka Zeno Machine, of course. The ontological primitive required is continuous directed movement. In contemporary physics the most natural and general analog for Turing-Tape is 2-directional quantum time symmetry. Turing himself just declared the intuitive precondition of analogical continuum as "infinite tape", but in constructive pure math approach to computing we should be able to demonstrate also a formal language to generate 2-directional continuum as the superposition BOTH L AND R. We can do that, and my approach started from redefining relational operators < and > as verbs symbolizing continuous directed movement, e.g. arrows of time. With this minimal alphabet we can express outwards movement as Dyck pair < > and inwards movement as the inverse Dyck pair > <. Cf. parallel movements of clapping hands, breathing, etc. We can start to construct the tape by first observing that with the relational operator semantics in-formation of increasing resolution increases between the operator pair: decreasing<increasing>decreasing. The process of increasing resolution can be done concretely Stern-Brocot style by concatenating mediants: < > < <> > < <<> <> <>> > < <<<> <<> <<><> <> <><>> <>> <>>> > etc. This gives theory of fractions when we give < and > the numerical interpretation 1/0 of the numerator element, and their first concatenation <> the numerical interpretation 0/1 of the denominator element. From the second row interpretation 1/0 0/1 1/0 it's already obvious that we get a Stern-Brocot type 2-sided structure of totally ordered coprime fractions, also when we continue to tally how many of each element a generated word contains. In this theory of fractions generated by top-down nesting algorithm the operator language level expresses fractions as continua (just like we teach fractions to kids when cutting cake etc.), and it's natural to interpret the denominator element <> symbolizing duration. The generated chirally symmetric word pairs in the operator language can be further interpreted as entanglements, and uniqueness of new mediants formally satisfies the condition of monogamy of entanglement. Defining chiral symmetries of the notation as reversible entanglements gives a natural Quantum Metric as the "Turing-Tape". The tape requires also separability of analog continuum into distinct character places. In theory of formal language that is usually done by the unmarked distinction between whitespace and concatenation. Defining concatenation as the mediant of whitespace is the formal language analog of Dirac delta. These current mechanical computers based on the von Neumann architecture of fixed word lengths are very limited compared to more general theory of parallel computing with arbitrary word lengths. Studying Gosper arithmetic of continued fractions in this top-down context is IMHO very interesting.

Hi NJW. Well, physicists would need some very intense reasons to relearn mathematics, before proceeding to their next physics theory or laboratory analysis: can you demonstrate any new physics resulting from your approach?? [I am not trying to be unkind, I am asking myself what would motivate physicists to go through a huge effort to relearn something, when they don’t see the *necessity* of doing so. It is extremely common in physics to perform various approximations and to assume limits exist and other dubious procedures, which then lead to results which are consistent with experiments. Physicists don’t mind using dubious mathematical procedures at all, as you are probably well aware. For example QED is the most accurate theory in ALL of science, but it relies on many many approximations and some rather unproven limit procedures. If you have something better, people will pay attention; if you have something equivalent, join the club (there are about 12 forms of QED); if you can’t show at least equivalence, the going will be tough and lonely.] ps I am not trying to discourage you, I am trying to clarify things just a bit. pss Keep making vids.

Well there is a lot of angst and anxiety amongst theoretical physicists in recent years, as the hopes for string theory seem to diminish, and as the recognition that as far as fundamental particle physics goes, we are theoretically not much further than we were in the late 1970's. Yes, we have discovered the Higgs, but that is an experimental triumph building on theoretical work decades ago. So there should certainly not be any hesitation in the theoretical community to find ways of moving forward in different directions. And of course that involves learning, or relearning, new things. How could it not?? Can I point directly to new physics that emerges from the direction I am proposing? No, because that is the job of physicists to work out. My job is to outline sensible and stronger fundamental mathematical understandings.

Gödel removed "completeness" at least from the reductionistic object oriented perspectives to mathematics. Mathematicians and physicists would do good to accept the undecidability results by Gödel, Church and Turing instead of pretending that math does not actually exist and is not a coherent whole. From holistic perspective (time, loops etc. top down nesting algorithms) "functional analysis" appears as partitioning, as mereological decompositions.

15:30 How non-analytic functions can be seen as "formal power series" ?
This is a magnificent insight. I am looking forward to the continuation of the classical to quantum series and the revelations this will bring. I'm curious about the exception of uniform circular motion being the place it is acceptable to cast the problem in terms of angles and still escape from the infinite process based entities - would be great to see the detail on that some time.

So you need to define infinity to make the rationals closed under the Cayley transformation. But you do not want infinity for the reals because it would be noncomputable. That seems inconsistent to me as it would make the Cayley transform noncomputable as well and negate your preference for the rationals.

These are two very different meanings of the words "infinite" or "infinity. One thing is to add an extra element, called" infinity" if you want to, to the set of rational numbers in order to get a nicer behaviour of this rational function. The other thing is that an infinite amount of information is needed if one wants to specify a real, but non-rational numbers by its decimal expansion. Some of these numbers (e.g. algebraic numbers) can be specified with a finite amount of information in some other way, but uncountably many transcendental numbers can't. That's essentially why Prof. Wildberger rejects the notion of the number line in the sense of the set of real numbers. (Moreover, he doesn't like to collect infinitely many objects in a single object and call that a set. Sometimes, the term "type" appears instead, but I don't see a difference.)

@WK-5775 I do agree that "point at infinity" is very unsatisfactory language for coherent pure math aiming for rigorous clarity. Potential infinity means on-going processes that are coherent with the Halting problem, so no big problem with infinity in the old Euclidean sense (except that we need coherent mereology to really comprehend Euclid). Much more problematic is the undefined term "point" as the word appears in coordinate system neusis.

I will give an example that best describes the dichotomy of exactness and approximation in pure .Mainstream mathematics,mathematicians derive the formula for 1/(a+b) from infinite series 1/a-(b/a²)+(b²/a³)-(b³/a⁴)+...&.This formula is true only when (b/a)<1. I have derived another formula which leads us to exact results: 1/(a+b)=(1/a)+(1/b)-a²+ab+b²/ab(a+b). This is true for all values of a and b and the conclusion comes out accurate. 1:09

the point isn't that "pi does not exist", the point is that "pi" typically used as a "number" is actually a stand in for some kind of function or process to generate a number and decimals up to a point. the important part is that using pi as a number covers up this abstraction, which may or may not be problematic when used in derivations of more complex mathematical objects

Hi Norman. Nobody does “infinite computations” in pure mathematics. You fundamentally mis understand the concept of a limit. We define pi as the limit of a finite sequence. Pi is a known ratio in the real world. We can mathematically transcribe it as what a sequence of rational numbers is approaching as the sequence gets larger and larger. It is a very real quantity.

Weierstrass' epsilon-delta is just infinitesimal calculus disguised in even more obscure language game of mathematically undefined "nearness". So "theory of limits" does not escape Berkeley's criticism against infinitesimal analysis, but is just another Zeno Paradox of infinite regress that would stop time and movement if it was real. Continua of constructive pure geometry are not reducible. Continuum is irreducibly holistic.
@bobuhi8 күн бұрын
Well-said! But, consider the simplest universe for just one electron's spin. The current continuum approach has 3 real degrees of freedom (1 complex number for spin up, 1 complex number for spin down, but sum of all square magnitudes must be one; classically, this is the 2D axis of rotation and the 1D phase of rotation). Don't you need to favor some directions/axes (i.e., make the universe a discrete grid) if you force your rationality?
@santerisatama54098 күн бұрын
So happy to see you again, dear professor! <3 I generally agree with the requirement of computability/constructibility. However, the basic empricial experience of temporal continuum/continua (e.g. duration of a program run) which is the precondition of causality is not reducible, as already Zeno showed by his reductio ad absurdum proofs against infinite regress. Computation science rejects "Zeno machines" because computation science is emprically grounded. I think turning he distinction between continuity and discreteness, between analogical and digital, into either-or question is incoherent view. In quantum perspective, it's better to consider that distinction as a superposition of both-and instead of an either-or question... which would just lead to the undecidability of the Halting problem. Even though graph theory is usually considered "discrete", totally or partially connected graphs are based on continua. Another everyday mathematical phenomonon of temporal continua is the use of Dyck language, which seems indispensable for temporal ordering of formal language computing, whether implied of literally expressed. by a pair of parentheses. What is inside a pair of brackets, is empirically intuited as belonging to a same continuous duration. Continuum is not reducible to rationals, if they are seens as infinitesimal points on a line. Theory of rationals based on bottom up additive algorithms only does not work coherently. For continua, we need nesting algorithms for decomposing continuum of quantum reversible time symmetry into fractional subcontinua. Stern-Brocot algorithm has shown how to, and we can expand on that top down approach. In the name of logical honesty, if somebody can demonstrate a computer program in which purely distinct objects of the formal language of a program make the program run continuously in continuous time, then please do so. Otherwise I stick with Turing's definition which necessitates continuous analogical tape that extend BOTH L and R as the ontologically primitive precondition for the Head to make digital choices whether to move a step in EITHER L OR R direction. If the Tape is cut by scissors where the Head is located, the Head can't move no more that direction and the program tilts. My interest in foundational study of pure mathematics originates from the Bohmian holistic paradigm, so I have not metaphysical prejudice against holism. Genuine holism includes both holistic perspectives and participatory reductionistic perspectives and requires both to be empirically coherent. Measurement problem of QM falsifies metaphysical reductionism, Bohmian holism does not have measurement problem. Even in Wolfram's idea of the Ruliad, it is bounded by temporal continua of entanglement serving basically same purpose as the Turing-Tape. . Zig-Zag paths of continued fractions along binary tree nested in Stern-Brocot type structures and continua in Taxicab norm, not discontinuous nodes. *** For uniform motion around the circle, here's an idea. In operator language where < and > symbolize continuous directed motion, we can form fractions by interpreting < and > as the numerator elements and <> as the denominator element. of the formal operator language. Thus the fraction 1/1 corresponds combinatorically with word string strings <><, <<>, ><> and <>>. From these we can form four chirally symmetric generaror rows a <>< <> ><> b <<> <> ><> c ><> <> <>< d <>> <> <<> a is substring of generator < <>< <> ><> >, From each of these generator rows a Stern-Brocot type two-sided metric of totally ordered coprime fractions in the unit interval can be generated by concatenating mediants. Row a can be associated with expanding movement from the starting pole to the equator, rows b and c as the equator turn and row d as the movent from the equator to the opposite pole. The presentation of the Möbius transformation was very illuminating and gave ideas of how to proceed from these basic intuitions towards more comprehensive theory of chirally symmetric transformations between the circle are quadrants and straight lines. There are various ways to interpret the process oriented operator language (cf. functional programming instead of object oriented) not just as positive and negative rationals, but also as inverse aspects of i etc., even as polynumbers as the study of box arithmetic suggests. Uniform motion is essential for cycloids, perhaps we might be find some day a way to rationally parametrize the cycloid arc in the operator oriented language, as distant dream that currently appears.

hard to take physicists seriously, given their religious prejudices. the history of scientific cosmology quotes them as saying that they cannot accept the "horror" of a central position of the earth. in the universe. they assume the earth to be moving, despite no evidence; the theories of relativity allow them to assume that apparatus change in length, making the whole practice unscientific and their theories a matter of affirming the consequent; they are literally insane--disjointed in thinking--in order to maintain their atheistic worldview. “People need to be aware that there is a range of models that could explain the observations… For instance, I can construct you a spherically symmetrical universe with Earth at its center, and you cannot disprove it based on observations… You can only exclude it on philosophical grounds… What I want to bring into the open is the fact that we are using philosophical criteria in choosing our models. A lot of cosmology tries to hide that.” - George Ellis
