    I have followed Stephen Wolfram for most of my adult life and his foundational work got me started using cellular automata for physics simulation in the 1990s. Forces like gravity acting on thousands of particles can be simulated through local interactions. Emergent behaviours like group spin and vortex formation can happen when particle-particle interactions happen on a continuous manifold through the imaginary plane.

    Brownian Motion was also once taken as a spontaneous effect, because its cause was not known at the time.

  • @dj098
    @dj098 ปีที่แล้ว +6

    If they were to exist, computationally unbounded systems would cover the whole space of all possible computations, and this would effectively bring about their own annihilation in the process. We could perhaps draw an interesting analogy between this computational perspective and the familiar philosophical idea according to which universal existence would actually be the same as nonexistence. In other words, if you want to say that something exists, then you have to make necessary restrictions to the range of the specific variable you are dealing with, in this case when using the predicate "to exist" to describe the every object in the universal set that is the universe itself. So, by this picture we could say that existence presupposes computational boundedness, and computational boundedness implies the distinction between different states of things, as well as the presence of abstract formal rules that govern their mutual relationships, but which are otherwise computationally irreducible from the perspective of computationally bounded observers.

    I’ve been thinking even if we were not computationaly bound, and knowing the exact position and velocity of all particles in a system, Heisenbegs uncertanty principle would not allow us to know the outcome of any interaction other than in a statistical way. So this to me harmonise with the idea that our reality is the statistical average of the muliverse posibilities. So the manyworlds is realy only one, the one we are so happy to experience?

    When he talked about this with Sean Carroll a few years ago Carroll said with the heat death of the universe there will be no large scale structures to be seen by any observers, computationally bounded or otherwise. Wolfram agreed with that and responded by saying there can still be a lot of interesting stuff happening in the universe it would just be smaller than atoms. which sounds like entropy is more than just the interplay of computational irreducibility and computationally bounded observers. it sounds like the death of observers.

    Another way to think of entropy is as information, _not_ randomness! There is a maxim in physics that information can never be destroyed; that if you were clever enough, you could retrieve it. The same way we do with hard drives that have been written over and written over. Yet, if you're really clever, you can extract just about anything that's ever been stored on them. In this same way, since stuff is always happening, entropy (information) is always increasing, most of it stored in the form of heat. But this heat is NOT random!!! This heat is actually information. So just as entropy is always increasing, when the end of the universe or "heat death" comes (if it does) then the entire story of the universe will still be preserved in the heat.

    Why does it happen that way ? Fascinating pod…
    Why does order go to disorder ?
    My father had kids bring their bikes for repair, if a wheel be bit wobbly he knew in an instant, ( the apparatus he designed, his truing machine, I tried it, incredible, so if a spoke, let’s call it a string, just a tiny bit loose, he’d know which spoke/string the problem, guaranteed no other person could determine in same manner without such knowledge to this very day & so wheel back to order, balanced, perfect, interesting & stunning what people invent.
    Nature therefore must have its own particular adjustment also, if happen to trip over it.
    Ever thought about a zebra, it’s stripes black & white, thermo, a heat dispersement mechanism, according to what I read, all differing, the herd, all look completely random.
    Then how about an eagle soaring with ease, following a patterned coarse, rules, the need for linear & non linear, thermo, the principal that variable temps, one drives the other.
    Our bodies temps, all organs a different temp so actually 5 pulses not one, yet remains that the overall body temp is but one temp, yes each temp driving the next.
    But take a look at what the overheated or under heated brain or other organs do, begins to malfunction.
    There must be endless variables in natures evolutionary process pointing to same, built in allowances for modifications endless in natures realm, would assume man made cannot reproduce same allowances & readjustments as need be obviously, the correct timing requirement, the bird designed to do exactly that, perhaps one of many reasons why DaVinci fascinated by bodies & birds, a brilliant mind far ahead of his time, went back over his early notes also.
    And if we knew what was in the minds of great thinkers, most of them unknown, & what nature can show us directly & indirectly, much discovered by accident, more than likely have many more answers than all the man made computer experiments put together.
    Yet what most people desire to know is, will today’s experiments & discoveries even if they be correct, what if anything will it genuinely help ? The problems that face us ?
    Whenever this question asked it’s skipped over, boomp, that not need happen, we not being smart just as curious as the speaker be, are we that demanding ?
    Perhaps advances in medicine, yet why our ailments increasing rapidly at record pace ?
    And earlier on in this pod, speaker says, why order to disorder ?
    Could then very well say why was the early earth on fire or why ice ages…
    obviously a requirement for the intent created, like why day & night.
    Imagine the endless vibrations planet earth emits, not just for us but would be absorbed by our own galaxy as msgs & absorbed by other planets in due coarse for whatever reason, the one system.
    A man made designed super computer is exactly that, simulation attempting to correctly adjust or modify overall as nature can, yet science heavily reliant on techno, artificial physics, simulations that may prove later incorrect ? dating apps do same.
    The more we hear, the more people actually do pose these bigger questions,
    Whats put out there they will, as we & computers don’t make the rules.
    All starts with big bang, I had put to me, all starts with small spark, micro to macro
    If speaker can compare our brain to a galaxy, both complex, indeed, great that comparisons allowable…
    The macro to micro, how can we know how big or small we truely are, considering that we comprised of atoms, have we increased or decreased in size if we understood our complete evolution…
    Do we arrive now in a form that’s derived from our consciousness of all of our combined experiences, loved how the pod ended, all of it

      @electricityofmind6300 ปีที่แล้ว

      Yes. I think that we are bound to our own definitions of "ordered" and "disordered".
      These definitions are set by the observer, and are part of the initial state of the system at the start of the observation. The initial conditions also include the state and forces and actors of the environment where the observation takes place. I think it is more a battle of definitions in a world of limited knowledge. If the end result means that we have predicted earlier, then observed a new phenomenon, then the science offered more accurately describes our reality, and I do not have knowlwdge of such a thing being the ruliad. Wolfram's tools are powerful in terms of math and computations when used in research and simulations, but I do not know of his theory predicting any new worldly phenomenon. Wolfram is trying to encapsulate a complete picture of reality based on math and nature science, as we understand them today. I admire him for his end goal but I am not convinced the ruliad is a cure-all theory

    W or Omega in Boltzmann's equation for entropy [ s = k.log W] is *not* equal to the total number of arrangements (microstates) of a system Wtot based on the macroscopic variables of Pressure, Temperature, Volume and number of particles! That is only assumed in order to reduce the Boltzmann equation to the classical equation for entropy change during a thermodynamic process ie where heat energy is transferred in or out of a system. The *truth* is Boltzmann's W is the number of microstates in any macrostate arbitrarily chosen by an observer which leads to the entropy of a system following the probability of the system being found in that macrostate (0 < W/Wtot < 1).
    Note probability and therefore entropy is *entirely subjective* being dependent on the choice of an observer. The probability is not a thermodynamic property but entropy is and it accords exactly with our concept of disorder and its inverse improbability with order which is why entropy is properly defined as a measure of disorder.

    Weird thing is you would say the Universe actually started in the lowest state being just hydrogen, but thanks to fusion it make the whole thing go. I see the problem is that things want to spread out as much as possible minus gravity. So I guess in a way maybe mass is mostly converted to light.

      I was wondering that too. Indeed, gravity, temporarily at least, reverses entropy by causing a cloud of gas to collapse into a star. But I found this on the physics stack exchange, "when matter gets compressed by gravity, a lot of radiation escapes, which you have to add to your entropy calculation." So I take that to mean that indeed entropy goes down FOR THE STAR itself, but the entropy in the entire system...ie that whole area of space goes up.

    DNA clearly adds complexity to itself over time. Living systems definitely seem to spring from pockets of negative entropy in nature, like whirlpools or eddies in the river of background global entropy of the universe. The whole of biology is an intricate game of impeding entropy. I would go as far to say computation itself influences entropy and when robust enough pushes back effectively against it. We shouldn’t systematically ignore these phenomenon.

      Living systems the way the universe accelerates the production of entropy. Living things are local systems of greater order that produce greater disorder in the rest of the universe.

    • @rizdekd3912

      There is a misunderstanding of the 2nd law of thermodynamics. It says that there is a tendency toward disorder. But keep in mind that it's talking about a universal tendency for all systems to go from order to disorder. So within a system....in this case the system is the entire universe or at least for us on earth, the entire solar system...there can be pockets/areas/instances where things can become more ordered and in which the entropy distinctly goes down...ie in living organisms. But this doesn't contradict the 2nd law because it just means that elsewhere (eg in the sun) the entropy is increasing that much more to make up for it.

Also, the first self replicating molecule must have existed in a pocket of “temporary negative entropy” prior to the living system being present.

It seems more like a suggestion, especially if one wants to speculate beyond big bang models.

    • @rizdekd3912
      @rizdekd3912 ปีที่แล้ว

      @danscieszinski4120 I don't believe that living systems 'violate' the law or that those are actually exceptions or that they put the law into question any more than water molecules freezing 'defy' the 2nd law of thermodynamics. The second law of thermodynamics applies to entire systems, not individual entities within the system. Things everywhere, all the time can move toward greater order...ie lower entropy as long as the overall system...eg the solar system, is moving toward greater entropy/disorder. Whole planets formed from clouds of gas due to gravity. They are more ordered than the cloud of gas, but to be that way they had to produce lots of heat. That was the 'price' they paid to form.
      As an analogy, I think of the law of gravity. If you drop a rubber ball over a hard floor. At first it obeys the law of gravity and falls downward, but after it hits the floor, it seems to defy gravity and come back up, all on its own. But really, it (and the floor under it) is storing the energy from its fall in its mass and then releases that energy causing the ball to bounce up.
      Also, the bouncing ball doesn't defy the 2nd law of thermodynamics. The overall entropy of the system is still increasing by the production/release of heat, but temporarily entropy is reduced (goes down) when the ball hits the floor.
      Think of life as a ball 'storing' energy and as a temporary reduction in entropy while the entire system...the entire solar system is gaining entropy.
      If you're interested, search "Entropy, Energy and Order in the Universe Posted on July 23, 2018 by Euan Mearns"
      I found the quote:
      "To generate that light [that powers the earth], inside the sun, 600 million tons of hydrogen per second is converted to energy. This is a massive flow of order (the atoms) to disorder (energy)."
      Also look up "Does Life On Earth Violate the Second Law of Thermodynamics?" by Robert N. Oerter
      "Any decrease of entropy (like the water freezing into ice cubes in your freezer) must be compensated by an increase in entropy elsewhere (the heat released into your kitchen by the refrigerator)."
      So the sun is gaining massive amounts of (moving toward higher) entropy and is moving toward disorder as it reacts and the potential is stored in and sent out as photons. Things on earth absorb the heat and entropy temporarily drops. That's how life can seem to defy the 2nd law of thermodynamics. The overall (solar) system is moving from order to disorder but small pockets within the system (life forms) temporarily get more ordered. That is not defying or contradicting the law, it is part of the law. The law does not say that every single thing, every atom and molecule or chain of molecules and combinations of molecules all the time everywhere always and inevitably moves toward higher entropy but that the entire system will move toward higher entropy. In billions of years, the sun will have used up all its low entropy and THEN the 2nd law of thermodynamics will have played out entirely...life on earth will no longer be possible unless some other 'low' entropy source is found.
      When you think entropy, think SYSTEM, not individual entities/objects/subsystems within the system.
