[@EpicMathTime]

1:53 He's saying the 5-dimensionality of a manifold does not stop it from being applicable to a world that is "3 dimensional" in any way, and that the 3-dimensionality of space may not be remotely related to the dimensionality of this applicable 5-dimensional manifold. A simple example, if I am manufacturing a product and there are 5 parameters that determine my sales, profit, etc. then the combinations of those parameters form a 5-dimensional vector space, and that 5d vector space is directly applicable to my manufacturing process, and this has _nothing to do_ with the three dimensions we move around in. Nothing. The mistake that people make is considering n-dimensional abstract objects without abstracting the notion of dimension itself. By talking about "visualization" of a 5d mathematical object, you're insisting on these being _spatial_ dimensions, IE, you are failing to abstract the notion of dimension.

By both Tegmark and Penrose especially I was taken back by their ardent neo-Platonism, and while passion is necessary, it's also refreshing to see that Grant is just as passionate without having that passion rooted in the presumption of ones own metaphysical system.

@@Michael-Hammerschmidt Would love to hear your take on Edward Frenkel's view about this topic. Thank Q

[@MusicAutomation]

One perspective is that all inventions and artistic works are discoveries. When we think we're creating something we're actually just uncovering links between concepts that already exist. For example, there is a link between force, mass and acceleration, and we have symbolically represented our understanding of it, but nowhere did a human "creation" occur, only discoveries. Similarly, when a composer writes music, he is discovering which combinations of frequencies evoke certain emotions or experiences. But a particular combination of frequencies is not created, it is found. The composer did not "create" the sound a triad chord makes or the emotions he feels when he listens to it. Same thing with inventions - they are applications of scientific discoveries that have been found to have a practical use.

[@cuteasxtreme]

All of our meaning is derived from our surroundings so the sort of alchemy of that is really interesting

[@SETHthegodofchaos]

I agree with this. It kind of reminds me of Karl Jung saying "People don't have ideas. Ideas have people!" If all concepts already exist and are just merely discovered or experienced, then you technically dont have created the concept yourself, you just discovered the concept yourself. Such thinking is actually quite nice because it encourages to look further and beyond, to be curious and to be willing to be proven wrong to gain more knowledge in the longterm. I think at the core of the Scienticifc Objectivity, such thinking is key (or at least very helpful) in order to remove as much personal, subjective bias as possible.

[@tudornaconecinii3609]

While I understand how on a deeper level you could argue that every invention is a discovery, I think you can define the two terms in such a way that they refer to distinct concepts with practical applications. In fact, I think this interview itself exemplified a way in which the distinction is quite practical. If it is true that math is mostly about discovery, then we can reasonably expect alien civilizations we will find to (partly) be using similar math to us. If it is true that math is mostly about invention, on the other hand, then that expectation becomes inherently less reasonable.

[@SETHthegodofchaos]

@@tudornaconecinii3609 The symbols used in math could be considered "inventions", so they most likely wont hold up to alien symbols, but the logic of math would be the same. Once we figure out the differences in each syntax, we will quickly see the same logic at work. Of course, that only works if the universe has the same fundamental rules across space-time. If the rules fluctuate or underlying constants are not actually constant, then stuff might be more weird to us than we can imagine.

[@KEvronista]

*"concepts that already exist"* concepts are a product of the mind. KEvron

[@pebre79]

Math is a way of defining relationships. When you discover relationships in nature you have to describe it using the representations/symbols of math. You can think of math as a very rigorously detailed language that he to be dense, concise, and accurate but its still a language that people invented to describe relationships we discovered.

[@latt.qcd9221]

Axioms and postulates are invented and the resulting mathematics is discovered. The Pythagorean theorem was discovered, but it was discovered after the required axioms and postulates necessary to deduce that were invented. Mathematics is merely inventing rules and then "discovering" the logical results of those invented rules. It's just that some "rules" are better at producing logical results that we "discover" that reflect the physical universe, but there's no logical reason why Mathematics must "prefer" some axioms over others merely because we arrive at results that make physical predictions. It's simply because we like to be able to use Mathematics to describe the real world that there is any bias in favor of such axioms and postulates that would give us such results to "discover."

[@canismajoris9115]

[@canismajoris9115]

Math is invented, but an alien will probably "discover similar math"

[@sailor5853]

[@chasereiter4760]

[@AntonyReed]

So glad I found others mulling over this fundamental question. Math can be used to explain the world as it is, or can be used to give "proof" of theories and ideas that can take humanity in the wrong direction. How do we determine true from false if the math is created to prove itself? If it is invented, how can the argument, "...But the math works." be allowed as an argument?

[@derekfrostbeard6419]

What do you mean by "take humanity in the wrong direction"? Which proofs have done that in the past?

[@mooselessness]

i think it's a really interesting question - how do we reason without logic? or are there forms of logic, independent of math, that allow us to bootstrap enough context to talk about math without using it directly

[@Yzjoshuwave]

An approach I’ve been exploring for the compressibility problem, is that our capacity to think and to measure physical phenomena is constrained by insufficient computational depth to recognize deeper aspects of variation. Complexity hides behind the relatively low computational capacity we have for conceiving the true depth of variation. It’s a sort of signal-to-noise ratio problem: deep details hide in the noise and we reduce complexity to make it manageable. What if it turns out that deeper methods of computing and measuring details of quantum jitters, for example, opens up the details of the blur and there are profound intricacies we can’t consider.... We just need our minds to fuse to AI in order to extract the extra depth of order from the data.

it's true, "math" could refer to the verb, i.e., the language we use, or it could refer to the noun, i.e., what that language is itself referring to. if one does not specify whether they are talking about the map or the territory, the argument of invention vs discovery becomes lost to semantics.

It's a good idea to keep Grant's very grounded take on math and physics when listening to Witten and others closer to the fields that pull physics into the direction of math. Grant's point at the end, about using math developed by our (possibly) simple biological brain gets something about the real world given successes of engineering, etc. - strikes me as profound.

[@Maniclout]

What is the difference between a discovery and an invention? What you discover already existed, you just had to find, in contrast to an invention. Nothing precedes the axioms of mathematics, they must have been invented. But depending on the set of axioms we choose, every result that follows from it is already determined. So I would consider everything except the axioms as discovered.

[@mhill88ify]

We may have invented partial interpretations of the existing unspoken mathematical axioms of the universe.

[@dedekindcuts3589]

On the last topic of it being surprising that the world seems to be describable through relatively simple equations, two thoughts: 1) It could a matter of us inventing compact notation and sophisticated concepts so that whatever is complex about the universe ends up appearing in a simple form on paper. The example is how the standard model equation seems to be surprisingly simple to describe everything in the universe, but actually behind each symbol is some insane amount of concepts buried within it. 2) It could be that the world actually isn't describable through simple equations - only some parts can. E.g. we think F=ma, which is simple, is the law of motion, but it is only valid to good approximation. The special relativity formulation captures more scenarios, but it still isn't everything, and we go to more and more complicated frameworks. In fact, many physicists have been looking for a "theory of everything" that can merge theory of gravity and the 3 other fundamental forces, on the basis that there must be a simple model that underlies everything. The fact that we haven't been successful could either be that we haven't tried hard enough, or that the world simply cannot be described simply!

[@aditya17lal]

In my opinion, math indeed was discovered. I think of the math that we use as a hammer, the hammer was invented but the metal was discovered. The metal is the math, itself. The handle of the hammer is the medium through which we perceive math i.e equations, notations, diagrams and whatnot. If we have the length of the shadow of a tower, the length of our shadow and our height, we can easily find the height of said tower (basic trigonometry). All the relations were already in existence, like the metal, but they weren't really useful until we equipped them with a proper handle. Math in our world is limited to real world applications (for the most part, I believe) but there are so many kinds of 'metals' which are yet to be discovered, and even if we do find them, there'd be those metals which the average human could never comprehend, we could never equip them with a proper 'handle', you can say. There's so much of math that already exists that we're sleeping on. TL;DR : Math was discovered

Spaces are mathematical abstractions that represent information about objects in terms of distance functions measured along dimensions. Abstract spaces of higher dimension can represent many things that are applicable, they simply are not needed for representing the position of a single physical particule in relation to an observer, and that makes them hard to see as our visual cortex is optmized for that specific application.

[@krzyszwojciech]

I tend to think that nature must have at its core something that's 1:1 congruent with a subset of mathematics, but then we extend that core, creating objects and abstractions way outside of it. Even though I can point to mathematical objects that I believe are not 'real' [like infinitely divisible _real_ numbers], I don't know where the line between the two is exactly. But assuming that extension is generally consistent in some ways with the core, no wonder a lot of it is useful even when it has no physical representation. Metaphorically speaking, it would be like inventing a map that has higher resolution, more dimensions, and more features in general, than the thing that's being mapped.

My I.Q. increased a few points just by watching this video.

[@andrewk3210]

Math is there to discribe structure, peculiarities, features. Physics is about finding homogenity, simmetries in the world we live in. Those two combine to form "beauteful" equations that govern our world but only if we apply them to very specific things that contain sane amounts of both structure and homogenity. One obvious edge case is biology mentioned by Grant at 7:40 and indeed we dont have any nice and clean equations to picture morphology of an organism based on its DNA. The magic combo of math+phys fails miserably here which proves that it's far from being an ultimate tool

It's basically a philosophical debate about what constitutes discovery and invention, which in some sense is a more interesting topic.

[@saulorocha3755]

There are 4 types of answers (or mix of these four)for the question according to 4 types of mathematic doctrines: a) Realists or Platonists: math is discovered, "mathematical concepts and properties exist in some objective sense and [...] can be apprehended (detected) by human mind" (Kline); b) logicists: math is discovered, Russel and Whitehead believed in the physical truth of mathematics and they tried to use logic to obtain analytically that knowledge, avoiding paradoxes (or at least trying); b) Intuitionists: math is an invention, the concepts created are not from experience (don't exist objectively) but are synthetic contributions of the mind; c) Formalists: math is invented, Hilbert said that maths should not be treated as factual knowledge but as a formal discipline, that is, abstract, symbolic, and without reference to meaning (though informally meaning do enter).

[@2002budokan]

Mathematics is the 7'th layer of our neocortext, because the 7'th layer is the highest possible abstraction layer of known creatures. Dolphins for example have only 3 layers. DL experts may approve this idea. "As the number of layers increase the abstraction ability increases". Thus, mathematics is invented by our brains, as our brains discover the world and ask questions about its mechanisms.

[@RuminRoman]

Math is a distributed, evolving, not strictly synchronized object. The host of which is the social network of the brains of mathematicians. Which is part of the social network of human brains.

Why doesn't anybody make the argument that math can definitely be invented as for example game developers can make up their own weird mathematical rules that will lay the foundations of the physical world inside the game itself. In that world you can have cases where 1+1 doesn't not equal 2 and the Pythagorean theorem is not valid. In short one can make up their own mathematical rules and apply them inside a world of a video game.

[@chrissabal7937]

The issue is that the equations we have that govern our universe do break down at some point. Physicists have traced back the timeline of our universe to fractions of a second after the Big Bang, which is the point at which we no longer understand the physics of what was happening. In the world of quantum chemistry, there are a lot of things that we don't have accurate physical/mathematical laws to represent. We still cannot analytically solve for the wavefunctions of systems with more than one electron. We only have numerical solutions for such things. So I would say that we only have simple, elegant laws for topics which are "easily" understood, and as we branch out into more complicated topics the mathematics grows in complexity to reflect that.

[@jbman890]

This is probably wrong, but how we ask ourselves how the universe is works is probably why math works so well. We are essentially able to conceptualise the ideas about the universe in such a way that we are comfortable with. These puzzles aren’t inherently “natural” in the physical world, we just have a way of overlapping them on what we perceive. It’s essentially like making analogies which closely resemble an idea and then applying formulations with what we have already figured out, probably wrong and nobody asked but 🤷🏾‍♂️

Machine learning can be used to learn new physics or math. For instance. Can you learn the gravity value of each planet from the motion of all solar planets? Use a all planets as the training set and ?pluto as the test set. To see if the model predicts it right.

[@therealjezzyc6209]

If by the "gravity value" you mean G then we already know it to be a fundamental constant of the Universe. If you mean "gravity value" as g then that can easily be calculated using kinematics. Additionally if G was wrong then General Relativity would also be quite wrong and Einstein wouldn't be so famous. Although if you mean "gravity value" as in the acceleration due to gravity on a planet due to all the other planets, then you're talking about finding solutions to the N-body problem. Perhaps the advent of Machine Learning could help understand these problems' solutions, but it'd be meaningless since ML might not give us a rigorous approach to solving these solutions, rather only values.

[@elmars302]

I'd say it's a translator from universe to what we understand and use. You discover something in the universe and you express it so it's some what easily read by others. In a world where there are like 6,500 languages (according to quick google search lol) each with different names referring to the same thing, math is just a common ground for everyone, regardless of what language you speak, think, whatever. Heck, i'd assume that early humans observed other humans from different part of the earth, and by observation and interaction, slowly learned what each other calls each object. And to think that humans from different places of the earth speak different languages, indeed makes you think how different would an alien species be...

[@fataliity101]

Just maybe, so many interactions can be labled simply, because in their basic form they literally are basic interactions. Like your example planets. It's 2 large bodies moving around each other, and they have their inertia and the gravity pulling on them. But once you get to 3, it gets immensely complex and complicated.

Does KZbin read my mind I was literally just thinking about this.

[@liammullen2144]

It doesn't read your mind but it does influence your thoughts.

[@kacperozieblowski3809]

Kinda, it uses artificial intelligence that learns from videos you watch and duration for which you watch them etc... to predict more or less what you want so in a sense it read your mind.

Concepts, ideas exist, they have independent existence. Mathematics, the scribblings we use are symbols, devices, tools, not the thing in themselves. A finger pointing to the moon. Knowledge has its own reality. We are knowers, knowledge can and does exist outside of our awareness. Mind is the foundation of matter.

Maths is similar to musical notes. musical notes exist in frequencies found in nature and humans have invented the way to describe that note on a scale i.e. ABCDEFG#maj etc. Therefore maths is just the human explanation for what is obvious to nature.

[@laxmanneupane1739]

One mistake people often do while trying to explain the real world with something abstract is the assumption that the world is real. An illusion could have all the features of another illusion which is Mathematics itself. I have no proofs but this is a wild gymnastic exercise that I propose which challenges the assumption of universe being 'real'.

[@fexcasanova]

Define real

[@laxmanneupane1739]

@@fexcasanova I can't. Its just what I observe people doing around. We ASSUME the world is real or whatever that means when we start with it & come to some conclusions & cherish what is uncovered but whatever is found is already here in front of us, in a way. The 'real' thing could be something not captured by our senses as in beyond the bounds of Mathematics as it is just fancy logic at the end of the day. The grounds for all this to be an Illusion is very compelling although how to approach such subject with our tools is what I wonder.

[@michakardach5847]

I agree with Grant about math invention/discovery, under the assumption that math logic is right. I wonder what are Grant's thoughts about that. If the logic behind math was discovered then all of our "inventions" in math are in fact bounded by the possibilities generated only through this logic. In particular, if we refuse law of excluded middle we would not be able to proof a huge number of theorems, including those with the biggest impact in our lives. Greetings from Poland! :)

I have asked in some forums that given that general relativity models the universe as a 4-dimensional coordinate system, whether the universe actually _is_ 4-dimensional, or whether the 4-dimensional math is simply used as a tool to make calculations easier, and the universe isn't _actually_ 4-dimensional. I haven't got a clear definitive answer.

[@mryman3656]

So everyone who wants a short answer: we invent the mathematics that helps us make sense of the discovery of maths.

[@ingerasulffs]

IMO and based on my very limited exposure, mathematics may be simple and beautiful for the mathematician or physicist or philosopher, but expand the compressions that looks beautiful, and it can quickly become overwhelmingly complex (hence not beautiful) while still not being able to model/describe all reality or even all of the subfield a formula is applied to.

[@BjornMoren]

I think math and logic are not separate from the universe, as if math and logic came first, and the universe was "designed" using math and logic. Instead I think they are emergent properties from the universe, so when the universe came into being, math and logic happened to become the ways you can describe it. Also, when they talk about different types of math, it would have been interesting to hear them give examples of it, because I think there can't be different types of math in our universe. The only thing you can change are the names of the symbols and procedures, not the actual outcomes or mechanisms.

[@Zenthex]

it's entirely possible there are aspects of reality that have no descriptive analog, but how would you know one if you ever came across it? is it godel incompleteness? is it quantum gravity? also, how would that information be useful to your every day epistemology? kind of just sounds like a non-starter question to ask.

[@Xpistos510]

Math is like logic. The principles exist abstractly, waiting to be discovered, but the EXPRESSION on paper and in writing is invented by the culture using them.

abstractions are a product of the mind. KEvron

[@fexcasanova]

@@KEvronista think about this way: the principles is a tree, the EXPRESSION is the chair. The invention is the manipulation of the principles.

[@winstonthomas4576]

Discovered! It’s in the way we think. Adding and subtracting existed before language. Even animals count, add, and subtract. Algebra is all about finding unknown variables on paper, but life is filled with unknown variables. Math is nature and a part of our being. Math on paper is just an expression of what occurs in our heads.

[@otisjacksonjunior9795]

Numbers themselves seem to exist insofar as their properties in relation to each other are discoverable using techniques of mathematics that are invented using syntax that we find useful.

[@KEvronista]

*"Numbers themselves seem to exist "* where do they exist, and what is the nature of their existence? what does "exist" mean? what are the conditions for it? KEvron
