    What’s missing, and I’m surprised Sabine didn’t pick up on this, is the relative complexity-increase or “notational compression” that is achieved between addition/subtraction versus multiplication/division versus exponentiation versus entire Taylor series (trigonometry). If those can be graded against one another then I would think that their ranking forms another log-log curve. After all, mathematicians wouldn’t have been compelled to devise a higher order operation if it didn’t provide at least an exponential advantage.

      Yes , I have always wondered that if acceleration is the second derivative (or rate of change) of the objects position with respect to time , and acceleration is related to gravity then: What does the 3er derivative of position with respect to time (or the first derivative of acceleration with respect to time) will be able to tell us about gravity or else.

      @lewebusl gravity is largely constant within the human scale. The trouble is transients like hitting a bump with your suspension while turning. Or in electrics with microphones and the resultant signals. It's taking an input and converting it to a desired output that sets the engineering mind ablaze. Outputs where the car doesn't spin out or the elimination of hiss of the mic by passing it through a noise filter processor. There is A LOT of math involved.

      @santerisatama5409 16 днів тому +2

      I've also gained loads from Wolfram's insights and have deep respect for the guy. Speaking math, however, we need to be as precise as we can. When Wolfram speaks about "computationally bounded observer" (like us), the expression in that context means actually "statistically bounded observer".
      Wolfram does very much wonder and even little speculate about what other kinds of observers could experience a slice of Ruliad in other computationally bounded ways.
      Traditionally that question has been approach by the scientific methods of the shamanic arts. I consider practicing geometric intuition, especially when it requires a bodily self-transformation such as shifting your perspectictive and attention e.g. to that of a flat lander, a shamanic art.
      The idea of Ruliad offers new language to discuss, contemplate and practice such geometric and computational shapeshifting. Obviously, adopting the perspective of a flat lander is already a major mold breaking in the Rulial space for a being used to 3D perspective.
      When trying to get a better grasp of relativity, Pure Mathematician Norman Wildberger approached to question by adopting the perspective of a 2D bat relating externally by echolocation. Norman told that for a good while he practiced echolocation by making clicks and trying to find his way around his home the bat way. .

    An interesting one is that energy is typically related to the square of something. And that doesn't seem to be arbitrary. For example, if energy were proportional to any other power of electic and magnetic fields, interference would not be compatible with energy conservation. And the energy being proportional to the square of velocity ensures that the energy is independent of direction. However I have long had the feeling that there's something deeper to the "squareness" of energy.

      This is why the quantum relation E = h f , energy proportional to frequency, was challenging for the early theory of QM. If you are familiar with the Schrodinger equation, this E = h f is the reason that it has a first derivative in time, instead of 2nd derivative like a classical wave equation. Obtaining an equation with wave solutions but only a first time derivative is what forced the inclusion of the imaginary unit i in Schrodinger's equation.

    I‘m not really surprised by this result considering the fact that statements and proofs in definition-less logical systems are known to grow exponentially in length. The exponential distribution of terms is probably just a consequence of us combining concepts and values into definitions (i.e. giving them names, instead of writing them out in most basic terms over and over again) and probably holds for (almost) all mathematical texts, not just those dealing with physics.

      I think that's an interesting insight about defining combinations of concepts into another concept leading to the exponential distribution in mathematics. For example, one can see that the need to use many addition's is saved by defining the concept of multiplication and the need to use many multiplications is saved by defining the concept of exponentiation.
      However, natural languages also define a word to designate a concept that consists of other words designating other concepts that combine to form the meaning of that concept. So, why does the distribution for natural language words usage differ from exponential?

    Your "two time derivatives" comment at 5:00 brings to mind a comment in C. Hartley Rogers book "Theory of Recursive Functions and Effective Computability" - "Almost all statements which (I) have been extensively studied by mathematicians and (ii) are known to be arithmetically expressible can be seen, from a relatively superficial examination, to have quite low level in the [arithmetical hierarchy]. As has been occasionally remoarked, the human mind seems limited in its ability to understand and visualize beyond four or five alternations of quantifier." So Rogers is pointing to limitations in the ability of humans to conceptualize nature as the reason for some of the regularity.

    Easy explanation:
    Natural languages ​​have low entropy while the language of mathematics has high entropy.
    Natural languages ​​contain a lot of redundancy and are very tolerant of a wide variation in pronunciation and spelling. They could be compressed significantly without losing any information.
    In contrast, the language of mathematics is already highly compressed and almost not at all error-tolerant. A symbol added or changed gives a completely different meaning.
    This difference of course affect the frequencies of used symbols or tokens.

    We can see that the more familiar operations are more commonly used than the less common inverse operations: multiplication vs. division, addition vs. subtraction, square vs. square root. And squares are used to replace multiplication, anyway. This is likely to be due to human preference. The former are easier for us to use, so we often express things using these operations. Also, we tend to factorise to make expressions use these operations:
    A - B - C - D will likely be written as A - (B + C + D) for convenience, and A÷B÷C÷D --> A÷(B×C×D). I think that largely explains the relative prevalence of inverse operations.
    Regarding the different types of operations, it probably depends on how we think of the world. If we consider the world in terms of waves, we'd see a lot of sin, cos, and exponential functions. Otherwise, sin and cos mostly appear for angular relationships, and exponential functions would be largely from statistical mechanics.
    Also, how many addition operations are counted in an infinite sum? Or for the total contribution of a large number of particles (total force applied by a mole of atoms)? I'm guessing it's the handful that are written for us to get the idea.

    I suspect the reason why we don't see third derivatives and higher is due to Fourier's Principle. Every smooth curve can be decomposed into a series of sine and cosine functions, and repeatedly differentiating these functions will get you back where you started, up to a scale factor. I also think that this could be used to simplify a lot of complicated mathematics used in physics. For instance; starting from Riemann's curvature tensor and working out it's derivatives repeatedly until you get the scale factor, then equating this scale factor to one, might show a useful constraint on the value of the cosmological constant. Tho I don't yet have the mathematical skill to work this out fully myself.

      Fourier series are periodic, which limits their application (e.g. in General Relativity the solution will exist for all t > 0 and not be periodic in general). Regarding your idea of a scale factor, sure for f(x) = sin(3x) you could say the scale factor is the constant in f''(x) = -9 f(x), but suppose you have g(x) = sin(x) + sin(3x) , what is the scale factor now?

I also suggest to read about chaos theory, with nonlinear differential equations, which is where the fourier technique strongly breaks down.

    Some of the simplicity comes from the structure of spacetime, it has 3 dimensions on macroscopic scales, and it's precisely flat, except for subatomic and cosmological scales. This is reflected in the laws of physics, which then preserved through all the emerging higher layers of reality.
    The reason for why spacetime is like that is mostly explained by inflation and the anthropic principle. Btw. if you want proof for the inflation model, just check the prices at your local supermarket.
    The other reason is that we use approximations, linear mostly, which hides the ugly parts in most cases. And if this fails, we just through up our hands, and use numerical models instead. Those are the same simple approximations, just used for each small bit of the problem, then aggregated.

    Many real-world relationships are approximately linear, in isolation, and we tend to look at things deconstructively rather than holistically to better understand them. By holding some things constant even when they aren't, we gain insights into the components of complex systems. Describing the whole system in a single equation isn't impossible, but it is very hard to fully capture complex dynamics in that way.

      I would add that when taking the first steps beyond linear approximations to understand the complex nonlinear relationships, scientists most often start with expanding a nonlinear relationship into a power series approximation so that the contributions from each higher order term can be determined.
      This is also a reductionist (or as you phrased it, deconstructive) rather than holistic approach to understanding complex nonlinear relations, but it has been very successful in modelling complex nonlinear dynamics in many scientific and engineering disciplines when the contributions from higher order terms diminishes rapidly with increasing order.

    Sabine , probably (I SUPPOSE!) the base of this regularity in Mathematical Physics is rooted in our GEOMETRICAL EUCLIDEAN idealizations of the Physical World (EVEN WITH RIEMANNIAN STRUCTURE AS SUPPOSED IN GENERAL RELATIVITY or usual Strings and quantum field theory ) .For instance , in DIRECT PROBLEMS Classical mechanics , point particle trajectories are "perfect" geometrical curves in the ambient space (smooth and differentiable) . And there is a theorem very deep in Differential Geometry called the Fundamental theorem of curves that say that is enough to characterize curves COMPLETELY by using at most its second derivative ON CERTAIN VECTORIAL CURVE'S OBJECTS (The normalized tangent vector -its "velocity". Its normal and binormal -its "vectorial acceleration" in R3 -THE SECOND NEWTON LAW SAYS THAT THE FORCE IS A VERY SPECIAL KIND OF VECTOR ; ITS IS ALWAYS IN THE OSCULLATING TRAJECTORY PLANE .NO COMPONENT ALONG THE PARTICLE'S TRAJECTORY BINORMAL!!).) ! . The same mathematical behavior of second derivatives objects for surfaces, three dimensional volumes , in General Euclidean Manifolds, etc.. . So it could be of no surprise or not natural that Newton-s Law for motion only uses second VECTORIAL derivative for determine particle trajectories .By the way , Kinetic energies only involve first vectorial derivatives . Kinetic Energy is always quadratic in first derivatives (The minimum principle lead us to second derivative for motion equations ). Higher order equations could occurs in Classical mechanics always as 'Dissipative" laws -Friction . Of course if you have "Fractal trajectories" like particles moving in a turbulent fluid which have only its position as a meaningful geometrical object (as a Newtonian Particle) and not a well defined point wise Newtonian velocity or acceleration as a non random motion , you must use now an object called Stochastic Ito derivative which has meaning only for the "first" derivative!!(It is a sort of a kind of ...integral!) . And about Higher derivatives in Mathematical Physics ? .They exists , but they are very! , very ill behaviored for usual Physics !. In Inverse Problems they proliferate . In Geophysics , the main problem on seismic prospecting are the famous Ill conditioned mathematical problems (lost of inversibility and continuity on the underlying Math ) .In my time as a Mathematical Geophysicist , I was studying Random Transforms for inverse seismic imaging problem which had the promisse to be less sensitive to mathematical ill possednes ! .Totally different framework from usual Theoretical Wave Physics ! . See the following (old!) venerable Book on ill posed problems - "Solutions of ill-posed problems" , Andrei Nikolaevich Tikhonov and V Arsenin . -1977 . & Feynman path-integral representation for scalar-wave propagation

    Great video, Prof Hossenfelder!...but I wonder if we might be making a bit of a leap by suggesting that this statistical pattern in physics equations is a "Law of Natural Laws"--as stated in your video title and "Meta-Law of Nature" in the original paper.
    The exponential decay pattern the authors found seems to reveal more about the structure of mathematical equations in physics rather than about nature itself. It’s fascinating and valuable for symbolic regression and other computational methods, for sure-but it’s also possible that these patterns result from human conventions and preferences in equation-building, rather than any fundamental aspect of nature. We naturally simplify equations with integers, familiar functions, and constants. So maybe this meta-law tells us more about the language we’ve created to describe nature than about the natural laws themselves.
    Perhap, "Scientists Discover a Pattern in Physics Equations-Could It Reveal a Meta-Law?"...might be a more accurate title?

    The reason integers predominate is simple. If you look at a small sample of any object the count of objects will be an integer. Lets say count the number of rocks on a hillside and the number of visible rocks is 112, so the answer is 112 rocks. But this is very simplistic as each rock is different in weight, size, and location. It is the simplification of the classification process and the simplified description that delivers the integer 112. I am sure many of the rocks were chipped or eroded severely but nobody is going into detail in saying the number of rocks is 67.7 when all of this taken into account as many of the rocks might be only one half of the rock or only 3/4. Half of a grain of sand is still a grain of sand.

    there's nothing surprising about it. anyone who understands the following laws and relationships knows exactly what it's about: central limit theorem (normal distribution), Benford's law, Shannon's entropy, scale invariant power laws (which also lead to self-referentiality and fractals), Pareto's principle, and so on. fundamentally, this is a matter of probabilistic and statistical laws, which has a mathematical basis, but since mathematics is universal (which is self-evident), this regularity is also universal.
    that is, the distribution of the first digits of numbers, the frequency distribution of letters in the alphabet (entropy), processes described by Pareto's principle (e.g. the proportion of marketing department spending that is meaningfully used), the distribution of fish sizes in the oceans, wealth distribution in economically under-regulated societies, the frequency of asteroids by size in space, and so on. why would it be any different in the case of scientific texts?
    ps: as regards the two examples mentioned by Sabine, power laws in nature usually have integer exponent because our reality is (or at least it seems to be) three dimensional. e.g. the inverse square laws are due to this fact, since energy is spread out in a spherically symmetric way (at a given moment energy is distributed on a two dimensional spherical surface). of course, it doesn't mean that fractional dimensions and exponents cannot be more accurate, who knows? but e.g. 3/2 is also a pretty common exponent in physics (due to the combination of the three dimensional space and the Pythagorean theorem). and as regards the second example (why third temporal derivatives are not relevant): it has both natural and artificial reasons. the artificial reason is that we could use third order derivatives e.g. for position, but velocity (first order) and acceleration (second order) are the most important ones, so we usually neglect the third and higher orders. but e.g. "jerk" in kinematics is the third derivative of position, i.e. the acceleration of acceleration. in reality, almost every motion has non-zero third or higher order terms, we just ignore them. but why are we interested in only the first two? well, this is the natural reason: because change (velocity) and change of change (acceleration) are the most important terms. the former is always relative, meanwhile the latter is always absolute. self-referentialisation (latter) always leads to absoluteness. this is why acceleration has such a super distinguished role in physics (e.g. in dynamics, in relativity and so on).

    Mathematics is not used to describe observations but to describe interactions. We only “know” reality through our interactions with reality. Mathematics is a product of adaptation of the community of neurons that is our brain. This is a self organized system where reason, logic and math, emerges as an optimization process (optimization of our actions on reality). There is consequently an image of ourselves in our image of reality built from physics. In other words you cannot separate reality from who we are and it is an error (metaphysics) to believe the image is reality.

Motor vehicle owners who are skeptical on what the impacts of using said car are not the problem. That falls back on a lack of trust in science, and as time goes on it becomes apparent that lack of trust is well deserved in some instances. If you want people on board with your science, do good science and let the facts speak for themselves. People are not "dumb." The average person has average intelligence.

About the paper, the sample is clearly too small and the choice that they made can bias the result but it's definitely worth exploring more, and repeat the study for c++ , python, and other programing languages, Math is a language but not a traditional one so it would make sense that the law is different from Zipf

    Math is based on classical physics. Infinitely small points are classical. They don't exist in QM. When you study what the math axioms say , they all use thinking in terms of Newtons classical world. So it is really a mirror of classical physics. QM is based on this math but if they develop a quantum math , it might work a lot better but currently no one is working on this. This kind of quantum math would have numbers that would be forbidden. Like between zero and one, there would not be a continuum of numbers, there were be gaps. There really has to be gaps because every single thing in the universe is a large wave function and it would have quantized everything, including allowed numbers. Zero cannot exist because of the uncertainty principle but in Newtons physics you can have zero. You just can't have an infinitely small point in math or any other thing because of the uncertainty principle. Your brain and thoughts and ideas are resting on top of a quantum wave function. They emerge from this complicated structure. Mathematical space is a mirror of real space. Numbers are the same as discreet particles. But we all know discreet particles don't exist , they are just high frequency waves in the quantum fields. True and false can co exist in a superposition as in a superposition of an electron that is either spin up or spin down. The philosophers forbid this but it really happens.

    its status as a law is debated. it is an empirical finding without a known basis. it is not alone in this. Tsylors law and the species area laws in ecology are also widely applicable but have no know basis. the species area law seems to apply from puddles to continents which gives it a lot of credibility in ecology but without any idea why it applies

    I understood absolutely nothing but I'm glad the maths nerds have something to be excited about.

    Pink noise has 1/f fall of in spectral amplitude. 1/f fall off includes many diverse geophysical phenomena such as earthquakes and atmospheric conductivity to name but two. Earthquakes is a good example, large ones always occur less often than small ones, following a 1/f law. Words are discete and earthquake energy is continuous. Perhaps lanuage is a form of pink noise, or pink noise is more meaningful than we now think.

      Is pink noise even a thing?

      @andrewhotston983 Are you theorising that only white noise exists, and that there is always some additional filtering/amplification process involved that produces a noise power spectrum other than the flat one for white noise. Noise is always noise, i.e. not a thing other than noise, until we investigate and understand its ultimate origins.

    In dynamics applications "jerk" (third derivative) is sometimes used as an effective cost function or as part of a regularization scheme. Control systems often work remarkably well if jerk is minimized. The point being that as sensors become more and more accurate, they become increasingly sensitive to disturbances and often require active control to get the most information out of their measurements. I suspect that higher order math will increasingly become more important in the future. It would be interesting to see if the law of numbers has changed over time as more sophisticated applications have been developed.
