So basically... Can math prove itself? No. But math can prove that math can't prove itself.

I very strongly wish mathematics was taught in a wider perspective like this video is. We teach mathematics as if it's a world onto itself, disconnected from everything. In reality, it's highly connected to history, philosophy, and nearly everything.

Math isn't a specific subject. It's a collective of ideas that apply to all things in life. It might be described as the "code" of life. People, especially in the educational context, struggle to understand this and even more to teach it. It ought to be taught that there are specific forms of mathematics for each subject to be taught. But I suppose it's easier to declare it a specific science, and to alienate the children and adults who struggle to understand this backward concept. I myself was awful at specific mathematics as a child. I still am, in many ways, but I have taught myself to learn each subject-specific form of math as I encounter it. I think of this as further proof that all parents, if they truly give a damn, should homeschool their kids. But, most parents give fewer fucks about their kids than about pets, so oh well. Guess we'll have to keep dealing with generation after generation of traumatized, ignorant morons.

@Marcus Nelson I went to different types some bog standard public US, private, free school,college and at home in both Michigan, England and long Island New York. Before going to university. I find what kind of education you get depends on the parents background and education. The more manual labour the environment the less value will be placed on learning. Observation, logic and the 4 principles of the scientific method will stand you well in navigating people.

godel was explaining psychohistory aka cliodynamics, the prediction of the future by using the past if we can predict what the past will be we predict the future but we cant predict the future only the past and we can't predict the future in the past only the past in the future... so its highly complex to say the least...the calculations are infinite indexes of historical databases of everything that can ever been catalogued into a tiny little quantum dot and to have our tiny little peon brain wrap itself around that is highly egotistical for our mental comprehensive capacity at our stage in development within the cosmos... we are just the smallest fragments that make up a seed that will one day cover the universe...

@Keen Observer The problem is that no matter how we define it, it will always have flaws. There’s an excellent comment above in this thread that explains it more thoroughly, but essentially Godel proved that any system strong enough to define basic arithmetic is either incomplete or incorrect.
John Doe
John Doe ヶ月 前
@Keen Observer Well, tell me when you've found a proper answer because as far as I see we're making things way too complex, more than it has to be. The point we struggle understand might just be that because it just is. Take existence for example, people always say that time is infinite but doesn't realize that while infinity doesn't have an end, it might just not have a start. The idea is that paradoxes are repeatable answers. They might be our "neither", we're trying to make something of it but what if it just is? Advanced mathematics won't get you very far from where you are now. You are free to take my word for it or go mess around and find out, that'd be a time waste. A time wasted on only defining infinity which'll be a small contribution to giving our existence a reason. Be warned though, you may just end in a downwards spiral, and once you realize and acknowledge it, it may just be too late for you.
Keen Observer
Keen Observer ヶ月 前
@John Doe And to go back to your idea of right and wrong, I believe "neither" might be a viable answer as there are some things are are neither right nor wrong. For example, if I ask the 2 questions: do we live in a simulation? Do we live in the real material world? What if the answer to both is "yes and no"? i.e We cannot live without simultaneously being in a simulation and in real space, and one cannot exist without the other, hence the answer "yes and no". I may be completely wrong or illogical but I am sensing that we may be lacking this sort of perspective in maths.

Physicists rarely question whether or not they *should* assume such and such to be true in the first place. Einstein at least had an axiomatic criteria (least number of assumptions in the simplest possible form which frames the most general kinds of problems). Even then, his long talks with Gödel likely helped him to come to terms with the fact that axiomatic (assumptions-based) mathematics which has prevailed for 3000 years is fundamentally flawed.

The more I learn about Turing the more amazing I realise his brain truly was. Ever since I watched The Imitation Game I've been fascinated with Turing, and honestly the fact that he was driven to suicide makes me feel disgusted at the waste of a revolutionary once in a generation brain. Imagine how far science could have come if he lived longer.

@Ben Botts ,may I recommend you ,,Man’s search for meaning “ by Viktor Frankl? I think you will like the philosophy he teaches. Now about the topic at hand, let me just say that rejecting your own sexuality is no easy feat. I do believe that the analogy @Outback Catgirl made is not entirely appropriate though. Breathing is the most basic need of (almost) all living beings on earth while sexual orientation might be only present in humans. While it may be caused by a difference in the behavior of the limbic system as many studies have proven, this does not imply that it is unchangeable. The behavior of every individual plays a big role in the development of the brain. And I think that here is where the real ,,choice” could in theory apply. And make no mistake, this choice is more akin to ,,I choose to live my whole life as a monk” then ,,I choose cereal for breakfast” And even then, one might never be able to radically change their likes and dislikes, just controlling the amount of control said ,,likes and dislikes” exert on their behavior. Thanks for reading my ramblings -An aspiring neurologist

@Riya Choosing one's truth in life comes with good/bad outcomes from those you consider family, friends, et al. I believe this is a choice. Being gay, straight, or non-associative (whatever the correct term is for that 3rd option) ... I believe those are all choices. If we cannot claim agency of our own lives and what defines us then we are subject to simply being rolled some cosmic dice in a game of universally bound craps where we have no ownership of ourselves. As before I have stated I believe this is a choice and not something we are inherently born with/into ... others do not agree with me & that is okay. I'm not vying for anyone to agree with me nor am I hoping for someone to shift my perspective or change my mind. I appreciate the feedback, even if I respectfully decline your belief; I am thankful to read others' thoughts/input on the topic. Some folks want to railroad me or paint me to be some ignorant clown. Which is awkward, to say the least. Have a good night.

@Ben Botts but why? it is not a choice, you wouldn't choose to be gay if it could lead to your family disowning you, being ostrasiced by the whole society around you, loosing everyone you love and literally being killed in some countries. you don't willingly choose that. it isn't a thing to agree/disagree on

@Ben Botts Odd way to answer the question, but I feel like the logic is more like: There is a group of people outside your door. One person knocks at a time, and as this happens a couple times each person is asking the same question. If you were to give the group an answer then the group of people will leave, including the countless ones who haven't gone up to knock yet. That saves you time and keeps you from having to keep going to the door and give the same strange response! Most people asking aren't angry, just more confused as we don't understand what you're implying. If you are implying something than we are trying to educate you on the contrary. There is nothing wrong with learning more.

As a working mathematician, the scariest part of incompleteness is that when I can't solve a problem, I don't know if the problem I'm working on is just really hard... or if it's actually impossible.

@Scott It implies both ways, we don't know if it is solvable or not. No point pondering if it could be solved in the future with far superior intelligence and better mathematical tools because WE DON'T KNOW. We simply cannot see the future so it is a waste of time to be thinking about it. The only way to know a problem is solvable is after solving it, but there is no way of knowing if a problem is solvable without solving it. Even chess, even though it is a "solvable" game, is extraordinarily complex. Even the most powerful engines and AI currently are not even close to solving chess, the number of possibilities being only one factor.
Usopper

@Scott Chess being solved by brute force is one of the most ridiculous things I have heard, especially when you mention it would be solved in the next decade or so (even if you give a problem an infinite amount of time to be solved by brute force, it won't always be, depending on the problem). I don't think you comprehend the number of possibilities involved in chess.

To show how important Turing is to compute science, I have never heard of someone studying a degree in Computer Science and not seeing the concepts of Turing Completeness in their math classes. Unless you work in specific fields, it's unlikely you will actively use any of that knowledge, but it's still very important to know.

Mathematics is amazing because it transcends numbers. The reasoning we find in math can be transferred to any logical problem outside math, and the building blocks of the technology that powers our world is made possible by math. So, my hope is that in the near future we can teach math in a broad perspective like this so that people won't grow to hate it, rather they will grow to appreciate it and use it daily. Math is connected to everything, so it's about time we started treating it that way.

Amazing Video... there was a time when i understood this better... now I'm still not sure I get it =) To me this is very roughly a formalized and airtight version of the paradox: "If there was a machine that could answer everything, you could ask it to phrase a question it can not answer. If it just tells you "that doesn't exists" it didn't really answer. If it phrased that question it wouldn't be a machine that can answer everything anymore. So in a way there can not be a machine that can answer everything." Any logical system, complete enough to ask a hole into it's own completness, can't be complete. Yet, it needs that capability to be complete. I think their fight boils down to a weird human mentality, where some people are intereseted in math because they consider it to a path to "perfect order and truth" while others, like me, are fascinated by it, because of its riddles and the way it lets you glimpse into the paradoxical and chaotic. I like questions more than answers =)

It is absolutely true the Alan Turing is considered the most important thinker about what computers are capable of. BUT... His designs had nothing at all to do with modern computer circuits. His computers, their circuit designs, were kept a tightly held State Secret by the United Kingdom until the mid-1960's. The UK only declassified them because computers of much greater power had been widely commercially available for years. These computers were based on the work of John Mauchly and J. Presper Eckert who designed, and built, a fully programmable digital computer with internal storage of data and intermediate results from 1943-46. It could decide what sequence of instructions to perform next based on the intermediate results. They then designed a _second_ computer which stored it instructions in the same memory as the data. NO OTHER computer did this: not any by Turing, which had knobs on the front that you turned to program the machine. Every computer to this day names the internal circuit blocks the same way that Mauchly and Eckert named them. In fact Mauchly and Eckert gave these machines the name "computer": ENIAC was Electronic Numerical Integrator and _Computer_ and EDVAC was Electronic Discrete Variable Automatic _Computer_ As Varitasium says, "computer was a job title for women" and EDVAC was an "automatic computer" which automatically did the job of these women. Turning's was called "an electromechanical machine" and was named "Bombe".

I work in theoretical computer science and love this video because it so closely relates mathematics and computability! The first time I learned about the theory of computation was an eye-opening moment for me and a small introduction to incompleteness. Whenever someone asks me what I do and what my field is, I tell them that the most famous guy, the guy who really started the field I'm in is Alan Turing. A nice way of explaining modern day computers is that they are equivalent to TM's. Great video!!

@Haytham Hammud Well I'm planning on going into academia, but there are some jobs in industry where theory is very important, mostly in research. It really depends on the niche you are in! A quick example: a friend of mine works for a subsidiary of a big company that produces chips and he does research on optimizing the building and manufacturing processes of these chips. But it is true that there are less jobs in theory than in most other parts of CS! I would definitely describe myself as a computer scientist/mathematician.

At 20:40 he states the Gödel Incompleteness Theorem the way I was taught it 35 years ago: Any system of axioms sufficient to describe arithmetic will either be able to prove false statements or will not be able to prove true statements, where "prove" means "to decide they are true." There is a corollary in computer engineering: all electric digital logic circuits, complex enough to do arithmetic, will have unused states they can arrive at from which they cannot return. In other words, every computer will need to be shut down now and then.

Our lecturer didn't write notes, gave us a ridiculous reading list of 20 very dense maths books, each over 1000 pages, and didn't record the lectures, all for an exam that is 50% of 1/8th of the final year that is weighted at 60% (so in total 3.75% of my degree). We are expected to understand the full history of maths from prehistory to know and also understand all the different areas of maths philosophy. This video gave me a fundamental understanding and allowed me to exit the anti-philosophy-learning stance I had taken.

Godel like Cantor did not see that change is a subset of Infinity. Change allows for a contradiction to operate as a constant in a stream of logic that changes an identity within a mathematical extremity. This fact do not make math incomplete. It simply allow for the growth of change which is actually an expansion of a set's identity given that any contradiction must contain elements of identity to the set in question. Any contradiction is based on finding a counter or opposite identity with like elements thereby making the contradiction a mirror set or a set turned in the opposite direction. Example: the elements of the negative number set do not contain any positive numbers within it but positive numbers do exist. Both sets have like elements within a larger set of change. Each of these sets have an equal number of elements that oppose the direction of the other yet both sets share the identity of likeness of size and division of spatial order. Here we have an order creating a disorder of self. A contradiction or simply an expansion of its spatial self.

Math is the most compressed simulation of the universe. Since the universe is infinite and not a perpetuum mobile it is completely reasonable that math deviates from the outdated human assumption that there might not be perpetuum mobiles when we take parts of the universe into focus - but not the universe itself. Therefore this hole never will get patched without creating another one. It's like imagining the borders of the universe - only that a border by definition consists of at least two sides - so what's on the outside if this border if not even more of that sweet little universe.

Cantor's diagonalisation proof, cheats by offering an impossible scenario. Think about it for the example to be true we must have a comple list with every real and natural number, let's say for the sake of argument that storing something infinite is even possible. Then it asks us to perform yet another impossible task in the diagonalization test of adding +1 and moving to the next number and so on and proceeeds to explain to us that when we are done the number resulting would be different than any of the listed numbers. But for us to be done in the first place the list has to end and if it end and we extract a number all we have done is make a really long list and made a number that would be on that list had the list continued. Here is another example so you can picture what im tryinig to say amke the same naturals and real numbers list but stop at the first natural number, now apply the diagonalization test by adding one to the first number (let's say again that you can be done with such a task ), what you are left with is a number that would be on that list had you continued to make it. What im trying to say it's that the Example plays with our minds limited capacity for understanding what infinite really means. Feel free to tell me if I missed anything

the completeness bit seems to reflect the"begging the question fallacy". it seems to stem from an implied static state, that the paradox is because of duplicity inherent in the work itself. if the definition is relaxed enough to imply scenarios where the reference palettes from which the word gets its "form", then the static state and the comfort it grants to the mind in its finite form changes. it is this dynamic inference that grants the joke of Jim being his own enemy its hilarity. as it is required for the joke to ignore the circumstances that make Jim his own enemy to be verified, or even true.

I see math as another language, where you have to just agree on certain things in order for it to make sense. If you look too closely at any object, it is made of energy, so in a way it ceases to "exist" in the conventional sense. I see math the same way: if you look too closely things get weird.

@Umar Ahmed Sigh... Yes, SOME of them, SOMETIMES, "once in a blue moon" might have crossed that treshold Also, a duel, although a very confontational act, is not "physical" one (at least not a duel conducted using firearms). "Risky", "harmful" and "deadly" - yes, by all means - but not "physical". Matter of "honour", "dignity" - but NOT a physical confrontation like in a drunken pub brawl. Anyway, the first post in this topic was about "mathematicians yelling and hurling insults at each other" (thus "getting emotional", but not "physical"). Others expressed their... doubt's, let's say - "why, scientists are the better breed - educated, cultural and all" - to which I replied "well, they're people too - they have emotions, they can turn nasty, or even spiteful" - and in fact they often do, as it is evident for anyone following "scientists' polemics". There's even that wonderful piece of a fiction story "How the World was Saved" - a "robots' fairy tale" from "The Cyberiad", a book by Polish writer S. Lem: _One day Trurl the constructor put together a machine that could create anything starting with n. When it was ready, he tried it out, ordering it to make needles, then nankeens and negligees, which it did, then nail the lot to narghiles filled with nepenthe (...). Only then did Trurl invite over his friend Klapaucius the constructor, and introduced him to the machine, praising its extraordinary skill at such length, that Klapaucius grew annoyed and inquired whether he too might not test the machine. "Be my guest," said Trurl. "But it has to start with n." "N?" said Klapaucius. "All right, let it make Nature." The machine whined, and in a trice Trurl's front yard was packed with naturalists. They argued, each publishing heavy volumes, which the others tore to pieces; in the distance one could see flaming pyres, on which martyrs to Nature were sizzling; there was thunder, and strange mushroom-shaped columns of smoke rose up; everyone talked at once, no one listened, and there were all sorts of memoranda, appeals, subpoenas and other documents, while off to the side sat a few old men, feverishly scribbling on scraps of paper. "Not bad, eh?" said Trurl with pride. "Nature to a T, admit it!" But Klapaucius wasn't satisfied. "What, that mob? Surely you're not going to tell me that's Nature?" Then give the machine something else," snapped Trurl. "Whatever you like." For a moment Klapaucius was at a loss for what to ask_ Unfortunately, that piece is a tad on a "lost in translation" side - you see, the original text was in Polish, and Polish term tor "natural science" is "nauka" (which could mean both "learning", "teaching" and "knowledge". Which had to be replaced, unfortunatelly, by that rather silly"natural" in translation - but that's not the biggest flaw here. In the original text after "Surely you're not going to tell me that's Nature?" came a line, from Klapaucius, "But the Science (= "Nature") is something completely different!" To which Trurls' reply was something like: "So, you have any better idea? [on what a science is]. Then tell that to the Machine, and it'll make/ create it gladly in no time flat". (Slavic languages are "pro-drop" and "null-subject" languages, as bot the pronoun and the subject of the sentence can be easilly deducted/ infered from the grammar of the sentence.) To which question/ challenge Klapaucius was lost. (= He didn't know what to say/ answer/ had no better idea whatsoever what "science" is supposed to be.) So anyway, because of the "plasticity" of Polish language (and other Slavic languages too), AND a highly "inventive" vocabulary of Lem his works are often next to impossible to translate info languages lacking a "proper grammar" - like, for instance, English). But I digress here... Cheers!

@jonasba276 Nice etymology: Middle English (in the sense ‘stupid’): from Old French, from Latin nescius ‘ignorant’, from nescire ‘not know’. Other early senses included ‘coy, reserved’, giving rise to ‘fastidious, scrupulous’: this led both to the sense ‘fine, subtle’ (regarded by some as the ‘correct’ sense), and to the main current senses.

26:00 perhaps im missing something, but i cant see how this is a paradox, yes it gives the opposite output from what the initial h+ does, but thats what h+ was programmed to do, so in my mind this isnt necessarily an issue with h+ being flawed, but rather how it was programmed being flawed. Im not an expert in math btw, but I am taking programming courses so im quite familiar with programming stuff that ends up not working for whatever reason. But that reason usually boils down to, "It's not the machine that made the mistake, it just did exactly what you told it to," which seems to be the case here. h+ is forced into an infinite loop if it halts, which makes 'h' do as it's programmed and loop as per the program code used. However, because its part of h+, the output ends up being a halt, because that's what the machine 'h' is part of is programmed to do. And of course the inverse would be true as well. Please do correct me though, i would love to learn why im wrong and expand my knowledge👍

So if I’m understanding this correctly the contradiction is that a system can’t prove itself? Like no system you can devise can prove the validity of the system you devised. Which sort of makes sense. You can’t measure a ruler with itself but you can use that ruler to make consistent measurements. It’s unprovability is evidence of one thing - it’s arbitrary. A formalized system of mathematics is still useful though it can do amazing things: provide answers and make predictions about the real world making it inductively true just not deductively true. I believe in philosophy this is like perfectly basic beliefs. At the end of the day things like the law of non-contradiction being deductively provable isn’t relevant so long as they hold up in practice which is perhaps what it means to be turning complete? I dunno lol

Although it appears unthinkable, if the models were allowed to go on forever the premise of life would eventually expire. As it is for numerology it would be correct in saying that each scenario is true. Probably, if prime numbers get rarer and rarer over time there will be vast expanses where there are no prime numbers. The probability of one will decrease and decrease. The question would then become how long you would be willing to wait until one appears. If the probability of one manifesting is longer than the amount of time left in the universe, then reasonably the relative nature would suggest that it is insignificant and therefore both answers would be correct. There is an end to prime numbers but technically there is no end. -you're welcome.

@Electro_blob 2 Sorry this post is going to be a mess because it consists of random points I thought of, rn I'm too tired to organise them all into a structured reply; if it's too incoherent I'll try to restructure it "Maths relies exclusively on intuition for its results" where are we getting this from? Other than geniuses (which tbf consists of a much larger than normal proportion of mathematicians) who say they 'just know' I don't think most mathematicians rely on intuition. I at least for sure don't 90% of the time whenever I do any math. Intuition is logic our subsconscious thought of that we can't find a rationalisation immediately for. But it exists. However we have no reason to choose the decision of our intuition over logic as it is only able to choose because it leans into our biases. You can explain why you get a certain intuition with logic but not the other way round There is nothing that intuition can tell us that logic can't given enough time; intuition is just efficient guessing so in a way it could be said it completes things in Polynomial time which would take logic NP time. The intuitionists also, obviously, used logic to demonstrate to others in form of their proof and used intuition only to guide them. Intuition may have ended up being indispensable, but that's not because it's somehow more fundamental, but rather that without the efficient guessing we simply cannot reach a conclusion with logic alone in enough time. 1. But we can't intuitively "know" beforehand whether a system will terminate or not either. In others words we don't have intuition for things that can't be proven logically. 2. So this would mean that logic may not be the most fundamental thing but intuition isn't the best word to describe the thing that is. 3. But, because we intuitively derive basic rules of logic doesn't somehow suggest that intuition is more fundamental, (side note this intuition would be quite different to what I had been referring to till now) it could simply mean that we are just wired to think this way. Why not some other way? Well, because this is how the world works! This is what is beneficial for survival. Same reason as why we see "visible" light and not X ray, we adapt according to how the world is 4. ; Also it might be that there is not something more fundamental than logic but something else just as fundamental 5. We can still describe the Turing machine each moment follows the next according to only logic of the fundamental rules Also that was very interesting to read, thanks for writing an in depth reply. Do you know if current mathematicians are working on reformulating mathematics

@Electro_blob 2 In this case it wasn't JPvid auto-deleting it, or else we wouldn't have gotten the notification. Its more likely he thought it through, changed his mind, and deleted them himself.

@Electro_blob 2 ik it's a lost cause but iirc in his second reply he said that the game of life you saw in this very video was also literally just that- emergence, do you think that is also magic? Don't remember the first reply though Kinda insane even this got deleted he didn't even say anything offensive

There is a fundamental flaw in the real vs natural numbers challenge. The way Veritasum is presenting it - is a trickery. It is presented as if natural numbers N are being opposed to the real numbers with the length of N, which is wrong. Obviously, the natural numbers from 1 to 100 will have fewer combinations than a real number with 100 digits in length. But that is wrong comparison. The correct one is comparing natural numbers with K (infinity) number of digits in it vs real numbers with K digits in it. So, if this task is presented properly without tricking the viewers into substituting of the natutal number count with the real number length, then it will be obvious that this task has a valid conclusion (see below). In other words, lets say the "infinity" (or "lim") is N, and assume it's 2-digit value (K=2). That means on the natural number side you have 100 possible values between 0 and 99. On the real side you have got "random" non-repeating values between 0.00 and 0.99. Please note, the trick in the video lures you into an impression that you would have more digits in the real numbers row, e.g. you could use 0.991 value, but it is wrong because of the premise that you have reached the N (in the natural numbers) and that is the "infinity". Otherwise you could say "well, whatewer is the last natural number, I will add 1 in front of it and I will get a new unused natural number". But the idea is - you have reached the limit. But this means, you are supposed to reach the same limit in real numbers that will tell you that there is no more digits to continue your real numbers. Therefore, we are playing in the same field and the limit is the same. So if we go back to our 2-digit "lim" for natural 0 to 99 where you have 100 variants or real of the same lim between 0.00 and 0.99. Now you can try applying "adding 1 to the digit" in the real row. What do you get? And the answer is - you get it duplicated. Or you have to violate the limit. So, the conclusion is - there are as many natural numbers between 0 and 1 as there are real ones. The importsnt understanding is that natural number 1 and real 0.1 are in fact: 0000...infinity...0001 and 0.1000...infinity...0000 And if their length is the same - they have have the same number of combinations. Thanks for reading this if you reached this line :)
