Fun fact: Einstein and Godel were close friends. Einstein once said later in life that he kept going to the Institute for Advanced Study (where they both had a position) just to go on walks with Godel. Godel once found a solution Einstein's field equations that he presented to Einstein as a birthday present. There's also a funny story where Godel applied for US citizenship, but his paranoia led him to conclude that the US constitution is inconsistent and allows for a dictator to take power. He then tried to present his discovery during his citizenship test, but the judge, a friend of Einstein, thankfully cut Godel off.

Democracy as a concept comes with it's optional self-destruct button. If you want to make sure that button is never pressed, you would have to commit undemocratic actions. In Turkey, what I mentioned was somewhat used to justify the 1960 coup that overthrew a democratically elected administration and manufactured a new democratic system. It was accepted as common narrative that a coup can be justified using the argument of the self-destruct button. Now it is believed to be unjustifiable. Which makes more sense. Wether you like the outcome or not, if you truly support democracy, you must allow the system to self-destruct democratically if the people wish to do so.

@Art Donovan Yep, never heard of his demise. But, I don't know why that's hard to believe. For, whilst he had a impact on a lot of things, he was pretty consistently a secondary figure. If you do research on WW2, Computers, Free Will, Transistors, or Code Breaking, Turing will definitely be mentioned, but it's not like his LIFE STORY is relevant to those topics. His contribution/education/background is mentioned, and that's basically it. His personal life isn't congruent with those topics.

This is the best video I have seen in a long time. You litterly blew my head so many times, the video is amazingly made and it is so interesting even for a teen like me who doesn't like school math too much and doesn't know math, school should teach us stuff like this because students will actually have interest in classes
lukkemela
lukkemela 11 saatler önce
This stuff is usually taught in courses like real analysis, discrete math or logic in universities, unfortunately not with all these cool animations :(. The course itself doesn't have so many prerequisites so you could potentially teach it to whoever knows what a limit or an integral is, but it's so difficult to understand certain topics and theorems that if you tried to actually teach these things to every high school student 99% of them would stop paying attention. And you can't explain some concepts non rigorously because it would be a mess to understand correctly what is what. For example you can take the part where he talks about "countable sets". But what does "countable" actually mean? It could look obvious but it's not. If you don't explain it in a formal and rigorous way, you wouldn't understand why Q is countable but R is not. This one was probably the easiest part (since countable is still a concept that you could grasp without formalism), but that's pretty much it. I would recommend to find the beauty in things that you are currently studying. Ask questions to your teacher if you don't understand why something is like that, be curious. You will eventually reach this part of math and it will be great if you will still have this curiosity! Or you can go to TRvid channels like "the bright side of mathematics" (probably the best one that I found so far) and learn those topics right now. If you like the way he explains things and cool animations I highly suggest 3Blue1Brown, another great yt channel!

The lineage Cantor->Gödel->Turing has one additional ramification: Rice's Theorem (1951). Wikipedia does not do it justice, failing to give a layman explanation of it. It is a very important theorem which generalizes Turing's answer to the Halting Problem. It predicted why UML would fail, why code verification software is snake oil, why some programming languages, contrary to marketing will remain hopelessly slow... Very useful indeed. Ignoring it has wasted billions.

Code verification is not snake oil, because they do not verify arbitrary powerful languages and programs but specific ones and they check certain properties. I would discuss this with an expert before making such claims. Theory and need in practice are not equivalent.

You're ignoring a key point: a program doesn't have to be perfect (complete) to be *useful* . Rust's lifetime analyser is an example; while it can't *always* prove that a Rust code is memory-safe (hence some theoretically safe codes will not compile without using unsafe blocks), it nevertheless can gaurantee, for some but useful cases, that such code don't contain a bug related to memory-safety. Even this incomplete code analysis tool turned out to be very useful and practical for removing a major class of bugs. It's similar for type systems, code verification tools, and description languages. Rice's theorem does tell that a perfect solution doesn't exist, but it doesn't tell at all that a useful solution does not exist.

Hi Derek, As a Hungarian mathematician, I feel somewhat sad because of you missing to refer to Janos Bolyai as one founder of the hyperbolical geometry. Though we know Gauss worked on the subject, he did not publish his results unlike Bolyai or Lobachevsky. Therefore,I would not deem him as significant contributor to hyperbolic geometry. By the way, the stoy where and how Bolyai worked on his theory and how he published it - in short, it became an Appendix (we Hungarian mathematicians respect this word) to a math book written by his father, for which he spent one year of his income - and what was the afterlife of the theory, how it reached the French Academy, would deserve a video on its own, I would say. Best regards, Tamas

I"d just like to point out that 'there will always be true statements that cannot be proven' (one of the first sentences in the video) is not quite what the incompleteness theorem actually claims. What it says is that in every sufficiently complicated formal system, there exist undecidable arithmetical propositions. That is similar to the difference between saying 'There is somebody, whom nobody knows' and 'For each person, there is somebody whom they don't know'. Undecidability characterizes formal systems, not particular propositions. Also, Godel never claimed that such undecidable propositions are true. They may be true, but we could only know that if we knew that the formal system they belong to is consistent, and we may not know that.
Peter Codner

so "there will always be true statements that cannot be proven' ; so or therefore what? Of what syllogism does that form a premise? Is it not axiomatic that a mirror cannot reflect itself?
Craig Gidney
Craig Gidney 16 gün önce
Yes, one of the particularly mind bending things about a Godel sentence is that you can add the axiom that it is *false* to your formal system, and still get a consistent system. Normally people (e.g. Roger Penrose) consider it obvious that these statements are true, but you don't necessarily create problems if you take them to be false. Another way to phrase Godel's theorem would be... "there's always a remaining degree of freedom in your formal system; another statement or its negation that you can add as an axiom without causing inconsistencies".

This is brilliantly explained! These problems are what got me interested in set thwory and the axiom of choice! I was lucky enough to run into these when I studied The Banach-Tarski paradox (an interesting topic for a video, if you have not covered it already)! This both shows the brilliance and power of humankind as well as its darkness and self-destruction. Two brilliant minds lost early from something preventable. Turing's case is particularly frustrating and ridiculous. The man literaly saved hia fellow countrymen lives as well as other countless lives. He shoukd be considered a hero, at least for Britain. But no, they drove him to kill himself over the most stupid thing ever, being gay. I don't care it was another time, shiw me where is the logic and humanity in that. How in the world is him being gay in his personal life the government's problem. It is not like he was indoctrinating children or somethin (even then he did not deserve it). Truth is we did not deserve Alan Turing. Britain certainly did not deserve him. And so many others have not had their stories told or their potencial shown. In his very short life he changed the world forever...imagine what he cluld have done if he had not died at the government's hands. And what Goedel could have further acomplished with proper mental health treatment. Deeply saddening.

An absolutely superb video, as always, but I have to take exception to the title. To describe something as flawed means you must start with a preconception of what something should be, and then find that it falls short against that preconception. To describe the flaw as fatal you must be assuming that the thing has a ‘purpose’ which its flaws prevent it carrying out. Surely we have learnt from Hilbert (and we learnt sooo much from Hilbert), and the experience you describe so well, that mathematics is just what it is. We can discover things about it, but if we have created preconceptions of what it should be like then that’s our problem - it doesn’t detract from the beauty. And if we have intentions of utility then that’s our problem as well (thank you, Hardy). Mathematics can never be flawed. But our preconceptions of what mathematics ‘should’ be often are.
Peter Codner

The term for which you may be struggling - and are spot on about preconceptions is "hidden premise." It is a preconception or assumption that borders on religion, which can be defined as any set of related unquestioned assumptions presumptions, preconceptions or norms.

@Umar Ahmed Still doesn't make sense to me. Infinity for me is an abstract concept. If something is countable it is not infinite by nature. Infinity is that unreachable number to which no addition, multiplication by a number greater than 1 and subtraction can be performed unto. Or when it is the denominator, the result is a perfect 0. It's just an abstract mathematical limit. Once you reach it, everything is "frozen" or "locked" mathematically. Cantor proof is nonsense. And no Hilbert thought experiment doesn't work because you can't perform a subtraction to the last room once it's occupied. Infinity - 1 doesn't exist because infinity is disconnected from the countable series. So you can't reach it through infinite addition. Such a set {0,1,2,3.....infinity} cannot exist.

@Mr Fl0v Depends on how precise you want that description to be. A box of electrical stuff with blinking lights is pretty accurate ;) Seriously, as I've said already, modem computers are based on von Neumann architecture. That basic architecture has been extended and tweaked significantly of course. That "are" stored program electronic computers. It has been quite a while since I took intro theory of computation though. If you want to learn more, great! Do a web search and maybe even look into taking a course. It is cool stuff.

Eventually my physics teacher asked to see it and told me to give up cause its impossible to solve and predict.

Thank you so much. This is a brilliant video. I studied Theology, philosophy and I am now reading for my MSc in psychology. I always struggled with maths until the past two years when I realized it is a language like any other we use. Wittgenstein's work on language games open my eyes to this block I had. Once you see maths as a language you realize how beautiful it is and see the world around you in "number" form. For example, trees, leaves even objects like rocks are not constant. They are "alive" in some sense as they are aging, composed of elements that are continually moving and aging. This can lead to the question do rocks etc have a form of consciousness? Are we all connected through different levels of consciousness with each other and the world around us? Your video on electricity shows there are energy fields all around us. Buddhist philosophy on the sea of consciousness. Mystic theologians who move beyond "language" to commune with God and mathematicians are all expressing the same idea. We have systems of languages, maths, our alphabet that try to express truth within that system or game. Using those systems leads us to new ideas, inventions, and as history moves onward in its beautiful and ugly dialectic. However, those systems themselves contain paradoxes, contradictions that keep the eternal dialectic alive. The "truth" that there is no truth, that language systems and games are useful but ultimately limited is a very freeing and beautiful realization. You can use it to "answer" the questions with those systems but at the end of the day can step away and leave the game. Some are unable to do this and that is where madness can arise. Thank you, keep making them they are excellent programs. They should be shown in all schools, then you may not get the question from children, what the point of learning maths, ill never use it. lol

Literally Mindblowing. I wonder if there might be some kind of interface problem between math (as an maybe "language of the universe") and "spoken language" which may lead to some kind of unsatisfactory results. Seems to me that at some point you always have to switch from math to "spoken" language and vice versa.

Yes we actually have to switch quite often. For example when you want to define the logical AND symbol, you need to use the english (or any other language) word for "and". It is not possible to define the logical AND without informal spoken language. This also goes for the logical OR or the existence quantifier or the universal quantifier.

A question about Conway's Game of Life being undecideable, is that a general statement or do exceptions exist? That also necessarily questions what "stable" means. After all, a single glider will go forever since nothing can stop it, but it's also not really meaningfully changing, so is it stable? And then there are systems that just tile a plane forever. Sure, the entire game of life may be undecideable, but could certain configurations be decideable? Or is this some fundamental problem with the language of math? We can plainly see a glider will go forever and not stop if it's not interrupted, and nothing will interrupt it, but you can't articulate that mathematically?

It‘s a general statement. There are very many starting conditions for the game of life that are decidable - a trivial example is starting the game with a single alive cell. It‘ll halt after one generation, and it’s easy to write an algorithm that will tell you that. Undecidability means that there is no possible algorithm that’ll tell us whether the game of life halts for an arbitrary starting condition. It might be able to tell us for a lot of starting conditions, but it cannot do so for all oft them.

This very thing was what killed mathematics for me in primary school. That, and the problem of measurements. As each measurement can be theoretically, virtually infinite in any measurement; in and of it self. I would ask my teachers my questions about this, and they would become enraged and accused me of being an impudent and stupid boy. Then I was very often extremely sick for long periods, thereby missing large portions of the curricula. When it came to algebra, I thought the full stops or dots were decimal points and reacted appropriately. My answers were howlers. So wrong they weren't even false. I did seek clarification on each occasion, saying I had missed a lot of instruction. Each would in turn claim they would tell me later, treating me as a bufoon. Later of course, independent of a school system I became an autodidact. Discovering that the dots were multiplication signs, as not to confuse the X from the • , algebra is extraordinarily simple I find. Though no longer applicable to my life. I did work as a Senior executive manager in the computer problem solving area for over 28 years. Not to bad for a high school drop out? Had they roused my passionate thirst for knowledge, who knows where that may have led? You see I was being challenged by set theory as a 3 year old, though my father didn't know it. I argued the point that 3 oranges are not the same as 3 Apple's. They are quite distinctly different altogether.

@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.

All because some people thought that they had the right to meddle in other people's sexual preferences. I don't care what other people say about this opinion because any arguments that you give will mean you are undeserving of any device that came from his discovery and innovation.

Hi Derek, I have a question for you. What numbers do naturally appears in nature? I mean, do we find 1 through infinity or are there numbers that can’t be found in nature like “2” or perhaps 18. To think that nature has a mind of its own is ludicrous but we can easily see the inner workings of nature most likely has its rules, like the hexagons on a honey comb or the pattern in an acorn. I have yet to see a perfect circle made by nature therefore a perfect circle should never exist. I am a true believer than nature invented math. If we were to understand and comprehend nature’s math and formulae I think we will truly leap our science 2,000 years.

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.

Well, let's say that science endeavors to explain everything (the "theory of everything", the "one-inch equation" etc). This video suggests that you'll never get there, and not only that , you'll never know for sure whether or not you'll ever get there. BUT, you learn all kinds of things that transform your understanding of the existence, and therefore the Endeavor is totally worthwhile. Like that old adage, life is not about the destination (the destination, of course, is death), but about the journey (everything you experience along the way).

Which is the biggest angst I hold against math. It, in how I have been taught so far, is definite. Now, I started watching this video with an expectation of pain from the examples of maths claimed definity. But was amazed at what was shown. And of course thankful to learn of this.

So if that's true, then maybe someone listened to you saying that they are watching this on a device that came about as a result of Turing's invention... but in fact just maybe in "their case" it didn't.

I don't know why but I love the idea of mathematicians gathered in a room yelling and hurling insults at one another

@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!

@MrKotBonifacy minus getting physical?! Galois died in a duel at 21. And wasn't Pythagoras rumored to have killed someone for proving that there are irrational numbers?

Well, I'm studying CS and the math is hard af to the point of considering dropping out. (And it's only 2 courses out of 3 years) Like the whole video allover I was thinking "what's the point" like 80% of the time lol. And I studied that stuff for months and have another exam in 2 months again because I botched it the first time.

At 20:01, the number g must be represented by g successor operations, which when encoded must give a number much larger than g. Ergo, the card he has created can't exist: the Godel number generated by the proof can't be part of the proof.

This video is fantastic. As an unscholarly non-mathematician, it took rewinding to properly understand some of the logic. When I did, I felt I understood how people could dedicate their lives to something so cold. But math isn't cold. It's attempting to solve everything. It's wrong in its conclusions, or the assumed logic it works with is unproveable or false; but it is proof closer than we as humans can. Even if it takes hundreds of pages to solve one plus one, it is the only true proof of what we hold in our hands. Mathematicians stubbornly refuse to believe that everything doesn't exist, and dedicate their lives to proving it, miniscule by miniscule. Thank you, Veritasium, for providing mind-boggling amounts of human research in a digestible size for my mortal mind to (hopefully!) comprehend.

Well done! I just want to notice that human mind is a special representation of reality that has no self-reference link to itself. The last question is a human mind is product of some supercounsessness system or it's finite product of reality?

Whose reality? If you experience any sort of pain that is undoubtedly real, or cannot-be-different, for you, but no-one else, so *whose* reality?
