Mathematics describes the real world of atoms and acorns, stars and stairs, with remarkable precision. So is mathematics invented by humans just like chisels and hammers and pieces of music? Or is mathematics discovered-always out there, somewhere, like mysterious islands waiting to be found? Whatever mathematics is will help define reality itself.

Lol, I can't believe this pedantic asshole. He's a Platonian.....not only he believes in ideas, but he thinks mathematics is the ultimate idea that explains everything.
Plato said only the philosopher could get us out of the dark and show us the light, so we can only hope enlightened mathematicians like him can show us the true.......Give me a break dude.
@@OjoRojo40 I disagree. Also they talk about all the bizarre math that doesn't appear to tie into reality. Eventually they'll figure out how even those equations tie into the natural realm. Philosophy can explain how everything works, but math can show the mechanisms that make that happen. Penrose even talks about how consciousness is probably a quantum phenomenon so don't go around thinking he's close minded or a small picture type of person
I am so interested to know what Sir Penrose thinks about the work of the Indian mathematician, Ramanujan.
Ramanujan's ideas were apparently so powerful and 'visionary'.
@@NicksterNOC You are proving he's close minded and so you are.
"they talk about all the bizarre math that doesn't appear to tie into reality. Eventually they'll figure out how even those equations tie into the natural realm".
The "bizarre math" could be a door for different forms of interpretation (again, it's bizarre but still math.....). Eventually they'll figure out how even those equations tie into the natural realm? What natural realm please... the natural realm of math???
"Philosophy can explain how everything works, but math can show the mechanisms that make that happen".
You are repeating what Penrose said and his essentialist narrow view of philosophy. That's why he believes in mathematics as the "real" true that will get us closer to the ideal realm (in a Platonic sense)
Philosophy most certainly can't explain how everything works, hence math like I said, will never have any response to the most fundamental metaphysical questions of humans.
"Penrose even talks about how consciousness is probably a quantum phenomenon",
I really can't see how this help his case. Consciousness reduce to a physical interpretation??? Maybe you can help me.
Thanks for your time.

Today he was awarded with Nobel prize.
Maybe that large part of maths applies to the dark matter part of the universe ? Which is huge compared to the visible one. So that would explain why only a tiny part of maths applies to the visible universe, which itself is a tiny part of the universe.
It's all relative man ;) and Penrose is massive in my universe .
I came to this video only after I learned that he got Nobel :)
Incredible! Thank you. I had no idea. Excellent news!
@@vasile.effect Why is he wasting his time on black holes when they can't explain why a snowflake occurs? They can't explain biology. Science is still locked in the past and the academics are just preening each others' intellects with these Nobel prizes when they are too scared to admit they can't solve the major problems with science like the contradiction between the 2nd Law of Thermodynamics and Evolution.No wonder the general public is so skeptical of scientists, because they are not holding each other to account.
It’s always a privilege to listen to the great mind of Sir Roger Penrose
He answered the question with more questions. A wise man
When he talked about molecules and atoms, in the beginning, I thought, nice! A mathematician who seems comfortable in physics. Then I searched him up and found out he has a Nobel prize in physics. I guess he's more than comfortable.

Dr. Kuhn, just to say your overall program and interviews are a gift to our world today. Thank you for creating and capturing all these wonderful discussions.
Roger Penrose was awarded the Noble Prize for physics when he was 90 years old; That was an astounding achievement. I am in my early 70s, I can only tell you younger people that to be able to think clearly an and creatively at that age is truly astounding.
eh, we're too dumb to even recognize if roger penrose was developing dementia or something anyway.
I am in my pre-fifties and I find that achievement unfathomable!
Well since we're all bragging about how smart we are - I'm in my late 80's, and surprised that Dr Penrose believes that mathematics is not an invention, but is " absolute " in some sense. I greatly admire him for his achievements - who would not - but I take issue with this statement. He himself invented Penrose tiles. Would he claim that these are not inventions but in some sense a revelation of something absolute ?
Why is there a Nobel Prize for Physics, and no such prize for engineering ? Such as suggestion is absurd of course. But it illustrates in a small way the difference between the real world and the abstract world of mathematics. Nobel Laureates have bragging rights in a way that many useful people grounded in the real world cannot aspire to.
@@crustyoldfart Harold, congratulations on being so articulate in your late 80's although I must say that your notion that mathematics is a pure invention is nonsense. It is a bottom absolute and, just to get your dander up, it is one of our insights into he nature of God.
@@trajan75 Thank you for pointing out that what I suggest is nonsense. The thing I always bear in mind when receiving a gratuitous insult is that it is delivered with sincerity, and am accordingly appreciative. Your second strategy of invoking God, far from getting my " dander up ", I take as a clear warning that any further dialogue on the subject is impossible.
For the benefit of others who may be reading this I would suggest that the conclusion that I for one draw from Kurt Goedle's result that mathematics can contain true statements which are unprovable, suggests that mathematics is a self-referencing system, no more, no less.
On a slightly different tack: the great Michelangelo is reputed to have said that the awkward block of marble he chose to work on had contained the figure of David within it all along, and all he had done was to reveal the figure. Could this be a metaphor for the history of the development of mathematics ?

@@jolttsp But also doesn't have a proper grasp of math to ask the next pertinent question, which is; why are those math patterns there if nature isn't using them? You can't describe something then offer no explanation for them! The reason why Penrose doesn't do so is because he's locked into tradition which is the opposite of the scientific method ; it's the same old anti Galileo stance; an argument from authority --and what makes it infuriating is - that Penrose is smart enough to realize it!
I wish… that as a kid, someone had described math to me in this way. That it’s something humanity discovered. It exists independent of us, it’s not all understood or discovered. And in order to predict how reality will play out, you need to understand math. It describes reality, past, present, and into the future.
Mathematics may make future predictions and depending on all sufficient factors known may describe present reality of which we are ignorant, thereby looking as if it created something. In other words, our mathematics cannot bring into reality that which doesn't exist. It's only an inbuilt fabric tool which have discovered, are using and learning from.

Icant understand anything guess im just stupid
That's proof that he is truly intelligent. People that can explain complex phenomena in simple terms truly understand it.
Contrast with arrogant professors who try to snow their students with lingo and jargon that took them years to perfect, and then they dump it on undergrad students and make them feel bad, which is what some profs want.
that means he understands it
As a protagonist in engineering for more than 40 years I still get bamboozled by the depth of maths and it’s relation to physics! (This was by far and away my favourite subject through high school) I recognise that this work is vitally important for human development but there is a point at which we have to make sensible decisions that mean we can develop in a cost effective and acceptably safe way! There is somewhat of a philosophical position to take!

Yes you’re right, because we have become so dependent on production rates, and etc we have detached ourselves from the philosophy of science in our western society and almost the entirety of civilization
-Is Mathematics Invented or Discovered?
Mathematicians: Yes.
Well actually he's giving a very precise answer in this case
He says that it is discovered, but saying it simply will deprive you of the path how to understand it.
Adding to that, It's only our language that applies to the physical world as it is.
Is the universe invented or discovered?
@@jnananinja7436 God discovered it when he was trying out everything what was mathematically possible. It must have been trial and error with no specific goal in mind, so you can't call it an invention.
Math professional here. Great answer. Fun question to ponder when you've had too many beers to drink or have nothing better to do (and the latter is rarely true.) I tend to think math is invented as a language that can be used to unravel scientific truth, but that's my opinion and I don't care at all if anyone else disagrees.
"Pure mathematics is, in its way, the poetry of logical ideas."
-
A.E
🥺❤️
This is not philosophy philosophy pertains to single statement giving multiple logical meanings. All religions on earth are basically philosophy because every reader gonna take different meanings out of it. Mathematics, NO WAY. 2+5 is still 7. And in year 3022 it will still be same 7-2= 5. Same Math is a language and humanity's logical mind operates on it without a sweat. It is unchangeable by our feelings and moods. Science doesn't change of reality based on our moods thats why Science and Mathematics are always used together from where i came from.
Well, doesn't that beg the question. I believe we can only say for sure, that it is 'our poetry of logical ideas', not 'the' poetry. Maybe it is, but probably we will never know.
Delightful interview to listen to.
I had to watch it many times, because at many points my mind went far away thinking about what they'd just said.
Very good!
My thoughts exactly. They would make wonderful dinner guests. I've often wondered whether the apparently trivial or superfluous aspects of mathematics is a clue as to what we might be missing out there in the real world.
I’ve always thought “Mathematics” is universal, we just invented a language for it.
That is right do not let the "skeptics" twist words around and make baseless claims about mathematics just been an spontaneous chemical process with which humans are able to calculate things in order to achieve certain values that help us in the day to day as it further clouds the evidence that there is far more to the Universe that our minds are currently capable of seeing and understanding. Wether that is something akin to "God" or some grand spiritual power rest assured it's more than likely more real than the bigotted naturalist dogma that the skeptic community profess as fact.
Mathematics is the language. The thing it describes is just "what is" for lack of a better label.
It's like saying "[the things described by] English is universal, we just invented a language for it" which is technically accurate but also sort of an uninterestingly so.
@@Jrpyify So you're saying the "discoveries" counts as "what is"? And that mathematics is the language we use to describe it? In the same way, English and French have a word for dog, Indian math and Anglo Math has a "word" (equation) for 1+1?
@@Jrpyify Mathematics doesn't describe everything though, such as the nuances of natural language, qualitative aspects of our experiences, such as feelings, emotions, and our inner sense of consciousness. Mathematics is part of our Universe, and there seems to be parts in it that could be even beyond our Universe, without any current known application. For example, we only need to know around 40 digits of pi to perfectly calculate the radius of the observable Universe to the width of a hydrogen atom. And we know that the Universe isn't infinitely divisible. At a specific point, we reach the Planck scale. Mathematics is all about measuring and making predictions. It is an essential part of our Universe, but it isn't the whole picture. We still have no idea how qualitative aspects such as being self-aware and experience feelings and understanding, are interrelated with quantitative aspects.
Mathematics can only describe those things that we know, think we know or suspect. It can not describe the unknown.
In that context mathematics is the language of describing those things we want to describe, in the way we wish to describe them and it's accuracy is only related to our own understanding.
Calling mathematics, or what it describes a discovery is like taking a video game or the computer it runs on and calling that discovered. Neither are discovered. It's just doing the thing it's designed to do, spitting out the information it was designed to spit out.
Remember hearing a great story. I hope I can tell it right. A mathematician walks into his colleagues office to find him reclined in his chair practically motionless with his eyes closed and then slowly steps back out saying “I am sorry I did not know you were working.”
it's weak story not great

because of the like... logic disconnect that seems to be the main hurdle for most people when trying to learn math, do you think folks like einstein or penrose are more lucky or do you think they would've been exceptional at whatever they did? in this particular circumstance, i find myself entertaining the idea of luck. for me, i just suddenly got it after years of overlooking and immediately realized that we must all have been doing basic algebra in our heads all the time, even when we're babies and even mentally handicapped people. hell even when we were covered in fur. math is native to the way the human mind works at least and i believe it's native to the way intelligence itself works. discovered for sure.

I would say, neither of both, but we deciphered and still deciphering it. Mathematics is a language of our universe and as with any unknown language, we try to figure out how does it work. Every time when we find out how something could be mathematically explained, we have deciphered a new area of this language.
Science is not like the ancient bone we dig up at an archeological dig. It is more like the conjecture we assign to that bone.
Science, in fact, is not a body of knowledge at all. It is a methodology, or the outline of one, for discovering knowledge. But it is the equation, not its solution. And it is an equation that can take many different forms. There is not one equation, or very, very few, that rise to the level of “law.”
Mathematics is no different. We didn’t “discover” it buried deep in the earth somewhere. We - humans - developed it. As the physicist Sean Carroll notes, equations are “just a way to compactly summarize a relationship between different quantities.” And “A function is simply a map from one quantity to another quantity.” Mathematics, in other words, is simply a system or notation used to attempt to understand the world around us - emphasis on attempt.

Nothing is invented, least of all mathematics, even things you thought you invented, actually you merely *discovered*, all "inventions" are actually discoveries.
What I find most intriguing about mathematics is that it seems to be a self annihilating language.
When we look at quantum mechanics and consider, just to name a couple, the work of Heisenberg and Schrödinger, what we see is that mathematics itself led us to a place where all calculations become void and irrelevant because it is impossible to mathematically predict the behavior of existence itself when we are faced with its particle-wave duality. I find it to be so poetic that mathematics itself had proven to us that the quest to understanding the universe/multiverse at its most fundamental functions will require a language that would be very far removed from the nature of mathematics.
Schrödinger wave function equation is fantastically simple mathematically speaking, very elegant and ez to kno by heart.
It just happens that we can't find the exact solutions of this equation.....just like countless other equations in physics (like the plasma equation form Botlzmann).
But we can discover some properties from the solutions, like Cedric Villani did with Boltzmann equation of plasmas, it even won him the Fields medal.
A group of mathematicians were trying to measure the height of a long flag pole but it was too high. A group of engineers came along and said they could help. They pulled out the flag pole and laid it on the ground and had no difficulty measuring the pole. The engineers smiled and left. The mathematicians scoffed at the engineers, "Engineers! We wanted the height, they gave us the length!"
Some ancient Greek dude stuck a one cubit stick in the ground and measured it's shadow to be 3/4's of a cubit.
He then measured the shadow of the flagpole and found it to be 15 cubits. Looking at the engineers and the mathematicians he announced: "It's a score!"

My intuition tells me that reality has a structure and math is an expression of that.
Its called Khufus Pyramid.
only information exists
@ayoub laarouchi proof is not availlabel and may never be. One problem is a version of The incompleteness theorem.
If you try to falsify the hypothesis that only information exists then you would have to so within the realm of information and mathematics .
en.m.wikipedia.org/wiki/Gödel%27s_incompleteness_theorems
It is a problem of a system looking at it'self , a self referential regress ad infinitum.
Another way of posing the question is equally valid ie
Is there anything other than information in reality and if so can you prove that.
This has has one advantage that if true that there is something other than information and and it is falsifiabel then it would not be a problem of the incompleteness theorem .
In an earler version of this problem was the refutation of Berkeleys immaterialism by Samuel johnson
en.m.wikipedia.org/wiki/Appeal_to_the_stone
Berkeleys immaterialism was given little recognition at the time due to its seeming absurdity
but in the 20th century it has become regarded as important in light of the incomleteness theorem and quantun theory

I love thinking about these topics. It’s gives me a great sense of awe at the natural world.
it’s the bomb
if you believe mathematics was discovered they probably still think Columbus discovered America.. periodtt
One thing this shows clearly to me its how crucial the a priori is epistemologically in a sound scientific method. At the same time, it's surely important not to mistake sometimes mathematical correlation for causative mechanism, and to remember that it's possible to obscure discrete causation with calculus' "smoothing out of the continuum".
Isn't that like Michelangelo's answer to the question, how he could make such beautiful statues, which was:
"I didn't do anything special. The statue was inside the block all along. All I had to do was to chip off the unnecessary pieces."
Exactly. Which is obviously incorrect.
The principles and the phenomenas are real, we're just figuring them out and giving names and labels to them.
@Jeanette York Are you saying here that math is fundamentally a mental experience? If so, why?
@@johnburnham6239 Nature is as it is, things happen in it even without our existence or awareness of them. The behaviour of matter and non-matter apparently follows certain patterns depending on their level of complexity, which apply to all of its parts. The apparent fact that there is this consistency at some level is what gives us hope to understand everything, as a random, chaos sandbox of particles would defy any attempt to intelligently interact with it.
Now what I call Mathematics is the collection of models, tools and language that allow us humans to analyse (past) and predict (future) phenomenas qualitatively and quantitatively, to derive certain characteristics of them that are used for purposeful considerations and to communicate findings between ourselves effectively. What we always work with are models. Models simplify reality from lumps of matter consisting of inconceivable complexity down to primitive representations like points, lines, spheres, cubes. As the world changes, we update those inner models and all of our rational process is done on this model, while being aware of significant differences between this model and reality to a certain extent. Also, across time we discover new models, such as in astronomy the flat earth model -> globe earth model or the geocentric model -> heliocentric model. As those methods of simplification become more effective at retaining detail, our predictions become more accurate.
Personally, I'd replace the word "natural law" with "natural pattern", as that would further outline the fact that the behaviour of nature is independant of our understanding of it. We're merely observers and we're working on efficient simplifications of reality to run certain calculations and algorithms which we found to be useful. Math observes patterns. Why those patterns are what they are may be a question for quantum mechanics or beyond our horizon of material analysis, philosophy.
MrSaemichlaus so I apologize for not specifying in my comment, but it was addressed to Jeanette York. So I wasn’t assuming any of your meaning.
But since you’ve made a comment, it does seem to me that you, like her, are calling math a mental, human thing. It’s the language that’s math. Language is fundamentally mental in origin.
Also, “models,” “tools” sound like they can mean many things... A scale, a ruler, and a toothbrush are tools that might help me predict the future or past, but none of these is a piece of mathematics.
And it seems to me like pure math has no necessary bearing on the physical world at all. So math wouldn’t fundamentally be about “analysis” and “prediction.” Though also I see no reason why one can’t analyze a prediction...
Honestly I was under the impression that analysis just meant “a breaking up into pieces” as opposed to having some reference to the past.
And I can’t think of an instance of math describing anything in a non-quantitative way.
As with anything else as well
systematic self organization for some reason I got a notification for this comment... were you replying to me? As in everything’s a mental experience?
Mathematics emerges when you try to understand relations in a complex system. It just happens that in our universe everything seems relational so it makes math a good candidate to understand it.
I think you have the best definition here
That is an excellent way of understanding it.
Let me change your statement a lil bit. "It just happens that the interpretation sensory data collected by our consciousness seems to have relations"

After combing through and scanning over all these provocative vid titles, I think I've found the equivalents of gold here on this channel. I'm about to binge all of this.
What I understood from this video, mathematics has two functions, one it enables us to understand the behave of objects and fields, either they are classical objects or quantum particles, either field or quantum field, the second function, mathematics serves the reality that not need to be proven by any means, reality that stands there for us to discover.
It is wonderful that mathematics describes the world very precisely or that the world functions in such ordered simple matter, that from adding and substracting you will eventually figure it out
this was great. so thrilled to think how much more of mathematics might be understood to in fact relate to reality as we experience it, and possibly unite physics and metaphysics.
I love Penrose so much. I feel intuitively and logically that his answers are correct about mathematics being a discovery. Our labels of math and language are the invention, the reality always existed.
I'm not a mathematician and I struggled with it in school but I completely agree. It always seemed that way to me. Like, mathematicians were in fact simply inventing a useful language to describe naturally occurring phenomena. I always liked the concept of math and I feel like if I had had more patient teachers I would have really gotten into it.
I simply thank the better sense to put an end to square root on reaching iota,at times I feel tempted to carry it forward similar to logarithm.
The subject of the video (and of course the discussion) are fascinating, but aside from that, I'm very happy that a video such as this reached over 2mil views.
One of the best short discussions about the topic of philosophy of mathematics, and with some insights into the interactions between mathematical structures with the real world. e.g. what Eugene Wigner called "The Unreasonable Effectiveness of Mathematics in the Natural Sciences". He has what I call a beautiful mind.
I like Penrose, he seems like a very humble man. And the interviewer is likewise. Two good men grappling with the most important questions in life.
Being surprised with the fact that math can be used to describe the world precisely is the equivalent of being surprised English can be used to write poetry that captures human feelings. It's a languague at it's best use. An endeavouring question one can make is in which cases math fails to describe the world accurately and also if we can ever realize it
It’s very fascinating, the idea that the physical and non-physical worlds operate independently - yet, work or interact between each other transactionally.
Ever since Ant Man came back from the Quantum Realm our understandings of things have really progressed at an amazing pace.
Yeah, and destruction too
So deeply interesting. Would love to see more.
The mathematical description is the most precise we know. So it is guaranteed to strike us as incredibly precise. In the nature of the case - we possess no greater precision to run it up against.
Mathematics is discovered.
The language we use to represent mathematics, is invented.
I really don't know what to say except "Thank you Roger!". Your thoughts are the beacon of our lives. And also thanks to Closer to Truth.
Whose truth?
You are a romantic
This is thrilling and fascinating to me, Sir Roger. The confluence of All Mathematics and All Physics is so beautiful and allows us to go deeper into the Reality and Truth of our Universe. And We, most probably, will never find a total solution. But the Theoreticians can dovetail with the Engineers, Scientists, Explorers, Practical People, etc. We can look forward to a testing and interesting future based on your thinking and your Associates and Colleagues. Thank you for your (summary) talk on this.
I'm amazed when mathematical ideas uncover things about reality that wouldn't have occurred to us if we hadn't been calculating a bunch of weird ideas. Sometimes it literally points the way.
Ahead of watching this, presuming the question isn't misleading, I will guess that the mathematical properties of the natural laws governing this universe is what we discover, and what we invent are systems for expressing them and leveraging what we've discovered both in practical application and also in the pursuit of new discoveries. Now to watch the video and learn how muddled my guess was.
Yeah, boiled down to it's most basic premise, math is just seeing a cup and thinking "thats 1 cup" then if you add another cup you now have 2 cups. It doesnt matter how you explain that, the concept will always be the same. You can have "1" or you can have a trillion lots of "1".. it just is that way, how we describe that is irrelevant... Any intelligent life would be forced to make the same observations eventually. All of math is based on these very simple foundations. In that sense we aren't really creating anything, just trying to understand what reality has already given us.
Agreed. I don't think it's muddled. Why math isn't a discovery I'd say is because mathematics is literally invented. It isn't a scientific discovery; it's a field and practice built on supposed axioms that have turned out to be very useful. These axioms developed throughout the course of human history, but started in a humble manner (counting: one deer, two deers, etc.). How these axioms were conceived were primitive and so primitive and subconscious that perhaps it's treated as a natural part of the world discovered. People are mistaken to treat mathematics and the phenomena that it describes well in the physical world the same.
As an EE, it is amazing how electrical parameters are so related in straight forward equations and that many of the constants that bind the equations also work well in other disciplines. The only thing that the math doesn't seem to fit very nicely is that a number of the constants are irrational numbers.
You should definitely checkout Eric Dollard’s books lectures... One of the most authoritative EEs alive & in the public domain.
this for me is one of the most satisfying videos on youtube an I've seen a few... thanks :)
We certainly didn't invent it, but we invented its language. When you look at anything, even if you aren't aware of mathematics, you can tell the difference between one of something and a hundred of something, even if you don't know what they're called or how to describe it. Mathematics is the language we invented to describe measurements of things around us, the labels and lengths we use are only a way to navigate through what is built into the universe.
really. like the mississippi river was 'discovered'. mankind had to 'invent' bumping into the river's edge. took alot of brain power to fall into a river.
This doesn't settle the philosophical debate though. It just punts it down the road a bit.
I believe the term mathematics is used to describe two things. At times multiple invented languages, and at times a prior reality of relationships. There are multiple math languages that can describe a problem - I have seen the same problem on youtube solved with both geometry and calculus.... both were valid languages to describe that solution - since a particular problem/solution is abstract until it finds a physical use you could argue that mathematics 'discovered it' before physics did... however since two pretty independent branches of mathematics can be used to solve a problem you can argue that they are just 'inventions'.
@Razor Face I don't believe the characteristics of the universe were invented by man.
@@jcr912 i think that to exist characteristics is necessary an observer to interpret it, without an actor there's no math.
He's also such a nice person (it seems). Example, at about 15:15, "It's a bit hard to explain that one too".
Looking at reality through mathematics, is the reason there is a separation between the two,
looking at reality through mathematics, geometry and the relationship between the two
will render a solution that is indistinguishable from reality.
What I think is fascinating is how often maths departments have musicians trying to break free! 🤔
I have been saying this question to people my whole life. I never knew it was an actual thing people like Dr. Penrose studied! I always thought discovered, just our units to describe things are "invented" but also based on discovered properties of reality as well.
"Reality"?
Whose reality?
If you experience pain or anything else that-for you, cannot be different, that is as real as real can be for you, but nobody else, thus whose reality?
o you suppose there to be a " reality"(whatever that means) other than the direct immediate personal experience of some particular being?-Some sort of vague generalised " reality"?
Whence you get that strange idea?

Thanks a lot
It is a wonderful video. I have to congratulate everyone who has participated in it, not only the great R. Penrose, because the most important merit is having shared it for free. Thank you. This video should be seen in every school in the world.
Mind blowing as usual, but greatly helped by Prof Penrose’s precision and clarity.
Maybe there are also platonic worlds of logic, music and morality, equally fascinating.
I’ve come to realise over time that mathematics is actually quite spiritual
Maybe you should read Greek philosophy... the Platonic world was one of concepts and an underlying ideal "reality"- whereas reality was only a shadow-puppetry of the Ideal. The problem I have with this view is that it suggests that mathematics has been advanced without the need of physical evidence, and also that pure mathematics has meaning outside of the physical world. There's been a lot of mis-steps in mathmatics (same as in physics). That's the scientific method... propose something, test it, re-assess it.
Plato lived in a time when there were huge advances in logic/mathematics - when the limitations of experimentation prohibited as many advances. Of course mathematics is infinitely precise - but as there was a transition from Newtonian to Relativistic theories, these were necessitated from the inability of the theory to explain reality. If Newtonian physics was able to account for all physical interactions, would anyone care about Relativity? We appreciate the need for different maths to better understand the reality we live in. Sometimes the Maths comes earlier - but it's relevance comes when it intersects with the real world. I'm really in favour of a discussion on the world of Ideas - but I also know that Penrose also uses a lot of methods to undermine non-physics/mathematics discourse, which is problematic (when it comes to things such as consciousness). I'm an aetheist - so I don't mind the lack of a watchmaker... but as a physicist I also fundamentally object to the idea that you need to resort to such things as quantum effects to argue consciousness (as randomness is a feature that is built into complex physical systems). His concept is to replace God with the Wizard of Oz (hidden behind an veil of uncertainty). This is intellectual commercialism.
@@AdelaideBen1 maths exists apart, in its own right, without our understanding of it.As long as there is space and time, there is maths.In pure maths there is validation through the existence of space alone.
@@ursulagwozdz1955 Er... I think you misunderstand where maths exists and where physics exists. Maths has no concept of "space" - it has the concept of 1D/2D/3D/4D.... etc n-dimensional coordinate systems. It says nothing about what "space" (the physical reality) means. Pure Maths has an important role in Physics - a crucial role - but Pure Maths doesn't need Physics, or ANY realworld anchor. That's why there is no branch of "Pure Physics" - but there is a Maths that is purely about the abstract. Much of Physics exists in the abstract - and much of reality can also be abstracted - but there's a real difference in physics and pure maths.
Also Pure Maths has no intrinsic concept of "time"... it has an abstracted dimensional concept, and you can extend this to a statistical concept which says it's more likely to move towards disorder than order, but there is no "pure math concept" of time AFAIK (maybe there is in which case I'd love to hear it).
@@AdelaideBen1 maths and physics are intrinsically linked.We agree on that.
At 12:15 Robert asks what the Platonic reality of mathematics means to or about the physical world (he refers to infinite structures or ideas)?
It means, I think, that the physical world (as we are able to perceive it) is but a subset of the possibilities in reality itself.
Answering the question:
The very basic thing we do in mathematics is to count things. That's what started mathematics. That's a human invention, no other living thing counts. Everything that follows is a discovery.
I have a problem with one notion suggested here: that we can or should quantify the accuracy of mathematics itself by how well the equations we've so far come up with model observable reality. If an equation, say the ideal gas law, pV = nRT, imperfectly predicts the volume of an amout gas at some given pressure or temperature, that is because the mathematical model applied doesn't exactly reflect the physical facts, not because 2+2 is not exactly 4. The answer is to make a better model, not to somehow tweak arithmetical results. No physical discovery needs to call into question the axioms and theorems of maths, only their usefulness. 2+2 can remain 4, whether or not there's a world to apply that to.
Today. Two plus two equals five. Correct?
@@alexlaverick6111 That would imply that 1 + 1 equals 2 and 3 simultaneously, which cannot be axiomatically. Thus, disproven by counterexample.
That comes down to whether there really is such a thing as "1", and not just the appearance of "1". That is to say, in it's application to reality.
"No physical discovery needs to call into question the axioms and theorems of maths." And yet there are mathematical systems that have applications in physical systems that do exactly that.
"keep your mind open to the possibility that 2+2 does not equal 4" -Jubal Harshaw.
Mathematics is the scaffolding onto which material reality is affixed.
Flash Fordon why not?
Math itself is inarguably, definitionally a human creation
But what it attempts to describe already exists and it can be a great tool for discovery. But it is a language we made up to make sense of the world around us
Penrose. I love this man.
I noticed Robert Lawrence Kuhn's repeated invocation of the idea that mathematics must be 'out there'. It seems 'out there' is his criterion for 'what really exists'. But the point about mathematics, is that it transcends space and time - it's not 'out there', it's true by virtue of inherent reason. The intellect's grasp of the transcendental nature of intelligible reality is fundamental to traditional platonist philosophy, but has been squeezed out of Western thought due to the influence of nominalism and, later, naturalism. Thank heavens there are some leading scientists such as Sir Roger who are fighting the good fight.
Very interesting....I think that materialism of people like Hobbes thought itself to have transcended Platonist philosophy but in the exploration of Quantum Mechanics its re-emergence was necessitated .....Heisenberg realized that visual pictures from the macroscopic world were NOT adequate to describe the sub atomic domain...To do that accurately you have to go into pure mathematics like Roger is describing....I guess mathematics could be seen as transcending time & space because it is an abstraction which is not a physical object that can only exist in time and space...But it IS an abstraction which pre-exists......In a way Heisenberg was using Platonism to go beyond not just Hobbes materialism but also Descartes.
@@walterevans2118 Google 'The Debate between Plato and Democritus' - a speech Heisenberg gave late in life. His Physics and Philosophy is also good. (It's a canonical text of the Copenhagen Interpretation.) The point about mathematics is that it's not simply 'abstract' insofar as it is also predictive. Many of the seminal discoveries of qm came out of the analysis of mathematical symmetries the gold standard being Dirac's discovery, or rather prediction, of anti-matter. Another example is Eugene Wigner whose Nobel Prize was for application of symmetries to nuclear physics. Wigner penned a famous essay on the unreasonable effectiveness of maths in the natural sciences. Plato will have the last laugh.
Jonathan Shearman...Yes, I've got Heisenberg's Physics & Philosophy. A great book particularly in the way he explored all the different objections to the Copenhagen interpretation...Yes, even if with the measurement problem of electrons we cannot have mathematical certitude between momentum & position in observations mathematics has an incredible predictive power in the physical world...This has led some to call it a useful tool which is invented but it also predicts THEORY.. I think Penrose is correct when he says calling it an invention doesn't really go far enough to explain mathematics ....& Heisenberg would have agreed with him otherwise he would not have developed his matrix Mechanics . In Athens in 1964 he explored these ideas about patterns in our minds called 'architypes' by Plato might have reflected the internal structure of the world.
Can I just say, your vocabulary impressed me.
@@walterevans2118 Aren't *all* abstractions pre-existents ?
"Mathematics" is a human contrivance used to describe change and motion. We can't be sure it's accurate over remotely vast distances and time scales. The ancient Greeks pondered this question.

I actually thought about this question a few months back
It was hinted at in this video, but Penrose considers himself a Platonic Idealist, in the traditional sense of that term. Most philosophers nowadays consider such notions silly and quaint, but Penrose makes a very compelling defense of it in his books. Everyone would agree, however, that Penrose is a brilliant mathematician; I would argue that he's also a pretty damn good philosopher.
Yes! I found that very interesting, almost Pythagorean! I think in your statement is the argument summed nicely. Remember it was the pre-Socratic Pythagoras who indicated the right triangle *is* a2 + b2 = c2, while a drawing of the right triangle is the approximation-who needs Plato here :-) . I'm inclined to say there are things we describe as right triangles in nature (such as the relationship among reactance, resistance, and impedance in electricity), in which Pythagoras has made a mathematical approximation of the reality. And I assert it remains an approximation, despite claims of relative accuracy. There is still room for idealism here, though!
Yes , hes very bright.
He's an awful philosopher. Platonic idealism is archaic. Idk why he would even attempt to defend that position. It's been well-established maths is just language, nothing more, nothing less.
@@Google_Censored_Commenter all language have semantics structure, it means the universe have a mathematical structure.
@@marcosgalvao3182 It means humans invented a mathematical structure that (currently) applies to our universe. And said structure is just labels, nothing else.
I read a quote from somewhere that said “if you could erase all science and religion from humanity right now, both would return, but only one would be exactly the same”. That’s not a knock on religion in my opinion, but truth that math and science is constant and unaltered, it is our minds that altered to understand it…evolved to understand it.
Indeed, how can something abstract, like "language", describe reality? Mind-bending!
