    He avoided the question of the turtle, just saying that there is a turtle.
    The problem with his argument is that just because we can't conceive something, does not mean reality has to follow those rules, or that it cannot contradict itself. It's simply wishful thinking.
    Also boundless pretty much means infinity, unless he wants to argue that something discrete can be boundless, which makes no sense.
    Moreover, values are not more real than functions, which are based on values. Discrete numbers aren't real, they are measurements, or they are nothing. Measurements aren't real in and of themselves, they need to measure something and be measured by someone. So sure, you can't measure infinity, you only measure values, and it has to do with our limited senses and brain. It does not mean anything else about reality. No measurement is totally precise so when you put it into a "value", it is also fake. Of course, two fakes will create other fakes if you compare them, and that could include infinity. Fakes eventually contradict themselves, this is true, and it is why measurements can't tell you anything about reality. There is a reason why philosophers did not measure things, it's because it is fake. Our language might be fake too, but at least it is closer to our perceptions and way of thinking and you won't contradict yourself if done correctly.

      Something can be discrete in one dimension and continuous in another, and those dimensions do not need causal influence on each other until certain fundamental properties of particles causes an interaction to change from one state to another, and that change is only ever going to seem more discontinuous the closer we look at it, but more continuous the more we think about it. You can get it all messed up in your head that nothing is real, but that's already faulty, your ability to tell what is real mustn't be either if that's your logic. The limited senses and measurements of the brain are limited, but *sufficient* for survival, we have brains still more computationally efficient than any known computer and we're running on meatware

    Wow, this is a cool argument that makes you realize that there is really no right way to do mathematics, and we usually just adhere to the canonized set of mathematics that has developed in the mainstream. Infinities and real numbers, and so on such as complex numbers, are assumptions made. Even integers and such lower-level math are all assumed in order to be used.

    • @neildutoit5177
      @neildutoit5177 3 года назад +3

      You're conflating ideas a bit. Yes we're making assumptions but we were never assuming anything physical. Even if infinities, irrational number etc don't exist in the real world they can still be very useful for describing things that are physical. Because you can embed discreet problems into continuous space, solve the problem using tools like calculus, and then transform the solution back into discreet space. In other words, studying infinity helps us to understand the finite.
      You're partly correct in saying that there is no correct way to do mathematics because there are lots of consistent sets of assumptions that we could validly chose to work with (we call them "axioms" usually not "assumptions" but whatever). But you're only partly right. because if the assumptions you chose to study end up producing nothing useful, then you're doing mathematics the wrong way. We choose to assume real numbers etc because we can do so without contradiction and the assumptions have helped us to do lots of very useful - and physically applicable - mathematics. Again this isn't to say that everyone must study the standard axioms systems exclusively. If you're interested in constructivist mathematics or finite mathematics, there are plenty of interesting and potentially useful things to study.

  • @jeffthompson1869
    @jeffthompson1869 3 года назад +2

    I agree that some infinities are a function like Pi, but it seems that if we are talking about time being infinite - that kind of infinite is not a remainder going toward a smaller fraction and so is no longer relevant. Is space itself infinite? The larger structures of space are only hinted at because the speed of light is so slow on such a scale. When it comes to doing math maybe limits make the equation work properly, but would it be accurate - especially with time and space?

    It seems to me that most of these complaints are cleared up with the simple statement "Inifinity is not a number" (and mathematicians and physicists don't treat infinity as a number)
    As for the "not a number, just a function" idea: fine, but the argument also applies to rational numbers. They're just an made-up way of expressing a relationship between natural numbers.

      Ever heard of “infinity equals -1/12”? This comes from physicists. So actually they do often try to make infinity a number, even though they aren’t supposed to (you will find that mathematicians disapprove what physicists do with math on occasion (such as with derivatives and integrals at times)).

  • @chapstickbomber
    @chapstickbomber 3 года назад +1

    The problem with our meat logic is that we treat a lot of emergent properties as fundamental. For example, it makes perfect sense to us to count items, to have well order, and then see primeness/orthogonality as emergent, but it is equally reasonable to assume the primes and then allow ordering/counting to emerge.

  • @neildutoit5177
    @neildutoit5177 3 года назад +5

    As a math graduate, I always assumed physics was ultimately discreet at the lowest level, but I don't see how that absolves us from having to work with infinity. Because if you have 4 discreet things in a square and the sides are lets say 1 planck length or whatever now what is the distance between the two diagonal points on that square? It's root 2. Now you can say root two is only a function but... then are you trying to tell me that that distance doesn't actually exist? How does it work then?
    Maybe spacetime curves in such a way that there is a minimum distance but no configuration of things which would result in any of the pairwise distances of things ever being an irrational distance from any other... I don't know.
    To be clear there are massive practical benefits to treating infinity as existing because you can take discreet problems and embed them in continuous space and then use calculus. But I don't think that that's really the point Bach is arguing against. Seems like he's asking whether any irrational numbers are needed to describe anything in the real world.
    What do you think? I'm genuinely curious.

    • @goclbert
      @goclbert 3 года назад +5

      I think the way out would be to see space as non-fundamental in which case there would be no real rad 2 distance between two points. That distance only exists as the projection from a "real" discrete Hilbert Space.

    • @matthewtanous7905
      @matthewtanous7905 5 месяцев назад +1

      The distance between two points would always have to be along the lines of the “graph,” as through the connections. So in a very large plane, the connections would approach this root-2 diagonal distance, but on the very minimal level, the distance would be along the edges of your “square” only - the diagonal simply would not exist.

    He does not play dice. He does not round. Measurements are discrete statements about a non-discrete existence, a simplification of reality. This simplifies reality to make it easier to describe and predict results, but when I say something is one nanometer wide, that does not make it one nanometer wide, it is merely a sensory limited approximation of the distance. You can get quite far without going to extreme depths as he seems to be saying, but if he thinks the limitations of sensing, describing, or calculating results makes reality itself discrete, I believe he's wrong.

    The problem with this theory is quantum space time uncertainty,if a discrete "value" of a function from a continuos wave pattern and let's say that function is minute of all convergent triangle which has no room for physical vibration for function change (not possible that's why infinity),so taking that discrete value chosen "first" will be changed at next discrete level with same space and time while recording due to same uncertainty in "measuring" that singular discrete value.
    So reality can be made discrete with minutely escaping vibrations,the summed discreteness of that function will continue to change in quantum scale.

    I think, and Joscha probably would agree, that my take would be that there may be a real possibility that infinity describes the sum of all sets of axioms.
    In other words -- an infinity isn't contradictory, perhaps, and this is pretty far out there and pure science fiction speculation, but is rather our notion of meeting a bound of a particular set of rules in a universe and beyond that set is another set of axioms that would contradict the 1st but operates fine within another bounded system.
    In other words -- the universe may have some "russian doll" like structure in which our spacetime is bounded by a particular set of rules and another is bounded by an entirely different set.
    That way, you avoid contradiction but retain "infinity". Just spit-balling. I am not a trained mathematician so these are just intuitions.

    It is simply impossible for there not to be infinity. The universe is infinite. Suppose that its not and the universe does have an end. For example, lets say you have a cardboard box and all of the contents of the box, or lack there of, is the known universe and the actual cardboard, all the way around, is the end. That's what I imagine a finite universe would be like; however what is OUTSIDE of that box? what is outside the 'edge' or 'end' of that universe? Suppose it's just empty space, is that empty space not accessible? Regardless, isn't 'nothing' technically, 'something'? Let's once again say the universe is finite and where it comes to an end there is some kind of void.. Okay... What is that void? What does it consist of? How far does that void extend? Does it extend to infinity? Perhaps it ends, and there is something behind that 'void'. Does that not extend to infinity?
    I don't believe there is a way around infinity. Change my mind.

      Life is fine, but you can make your own assumptions if it makes you feel better.
      To the case in point, I offer clear evidence:
      There is a discussion somewhere on RUclips where he almost apologises for being an athiest in a debate with some religious types. He is soooo apologetic, and tries to meet them halfway with platitudes and apologies that he is (sensibly) an atheist. In my opinion he needs not apologise and could have entered into worthy debate with them. A wasted opportunity.
      I find his explanations weak when dealing with complicated material (time travel, string theory, etc), and overly saccharin when dealing with other matters. As I initially described he is a weeknight 7pm "One Show" scientist (it is a low-brow magazine-type programme broadcast daily here in the UK). He can explain nice floaty stuff to your Nan or Neice, but he isn't much good for very much else.
      Just my opinion of course, but one I'm very much entitled to.
      More interesting is Neil de Grasse Tyson, Lex Friedman is an interesting young chap looking for answers (MIT comp sci. grad student), but the master of them all is of course Carl Sagan.
      ruclips.net/video/cIANk7zQ05w/видео.html
      Brian Cox is without a doubt useful for explaining science to children, young teenagers and people who read tabloid newspapers. However, if it was a choice of listening to him or watching a glass of water, I'd probably find the glass of water more acceptable.

    String theory (the "strings" that are being observed) is the beginning of continuity, the smallest observable element of causality.
    It's the liminal space (or moment) when pure possibility (chaos, infinity, etc.) crosses over into reality, when unknowable possibilities are reduced, when they are instantiated into something less than infinity. When possibility moves toward more certainty.
    This effect is (from our perspective) perceived as order -- matter, time, space, energy, etc. Cause and effect.
    It began with the cleaving of the universe into possibility and certainty. The unknowable and the knowable.
    It's the very essence of multiplicity, of perspective (i.e., relativity), and intelligence.

You can orbit the planet around and around never stopping, you are not travelling an infinite distance, you are traveling in a circle and there will come a day when the material you are orbiting no longer exists in its current state and if your state of orbit is reliant on the state of that which is no longer there, your journey will undergo a transformation.

      It depends on what you are measuring, and how you define existence. If you define existence as having instantiated at least once, then everything is infinite.
      This guy is also ignoring half the picture. Yes, a discrete function is what generates the Pi sequence, but the Pi sequence will never end (I.e. infinity) if you write it out numerically. Just like time will never end - it has and will always exist (I.e. infinity).
      On the other hand if you define existence as having some presence in the present moment (not even needing to have an impact on reality), then some things come and go and aren’t infinite. But most fundamental things, like the laws of physics, will always (I.e. infinity) be there in the present moment, impacting reality.
