I just don't understand where equation g came from. Why would it have been a contradiction to prove g, just because it said "this can't be proven"? If one had proven it anyways, Gödel's statement would have been wrong, yes,but what of it? Why did he write "this can't be proven"? Purposefully trying to MAKE a paradox by setting contradicting rules and then saying "See? Major problem, math incomplete." doesn't make any sense to me. If things naturally contradict, isn't it the axiom's fault? Shouldn't we just rethink the basics?
@@WritersMoment I didn't watch the video, so I don't know how they explained it, quite possibly very incorrect. However the point of the 2nd Gödel incompleteness theorem is if your axioms fulfill a bunch of desirable attributes (such as being able to prove all true statements about the natural numbers), then you can encode its own consistency. Those are known as Gödel sentences. As the axiom system can not prove that, it's therefore not complete if it's consistent. It's possible for an axiom system to not have arithmetic, but be complete and consistent, have arithmetic, be complete but not consistent or be consistent, have arithmetic but not be complete. So it's not possible to rethink the basics to get all desirable quantities. Math is not flawed tho, since having arithmetics and a consistent axiom system is possible and absolutely sufficient for everything that mathematicians do.
@@WritersMoment No, this is the sole exception. I clicked on the youtube video because it was recommended and after reading the comments I'm not very motivated to watch it either. It doesn't seem to do a good job at addressing common misconceptions.
I'm 75, female; I am grateful that I have had enough education to have at least heard of the people you reference. Awed that you explained it all so well that I could not stop listening. Lastly, so proud to have lived this era from beginning to undecidable end.
@@timomen1it may be frustrating to _you_ but why are you generalising it? What do you think you know that makes you so certain that others should stop mixing these things up? You may even be correct that it's pointless to do it, so what? Why do you try to rely on others to not feel frustrated? Do it yourself. No, instead you hope that by making aggressive comments on RUclips that life suddenly stops pushing your buttons. You are doing exactly the same thing as them, taking something you discovered previously and slapping it onto a disagreement that appears between you and others, the only difference is they slap philosophy onto math for themselves, only for the disagreements with their own understanding and observations of life. You, on the other hand, are trying to do it with others. It's apparent with how insulting you chose to make your comment, that you want them to behave in accordance with your ideas and that you don't even buy into your worldview yourself, otherwise you wouldn't need others to stop behaving differently to not get frustrated. Instead of behaving like such a narc, try to resolve your frustration with your life by yourself. Others won't save you, so stop being a dick, you're also saving nobody so no-one owes you anything.
Hello! How are you all? If anyone needs someone to listen, someone to talk to, or a friend. I am here to talk, listen, and be a friend. I hope you all are safe and well. Know that you are amazing and have rights as a human. I am very sorry for anything that seems bad that may have happened in your life.

It's the minimal necessary requirement to function as a programming language, so it's not exactly strictly a mathematical thing per-se. It's the computer science equivalent of 'can it run doom'.
@@BayesianBeing Math is fundamental to the universe, reality. Doom is coding to produce entertainment that enthusiasts obsess over trying to make it run on random machines not initially thought to be used in that way. Nonsense is when you’re so chronically online and out of touch with reality that you would essentially say running code for a game “compares” to reality itself.
@Linus Fu Yet neither can prove nor unprove logical paradoxes. The same way no one figured out why we can pin point an electron's vector and position separately at the expense of the other, and never both.
Exactly. If one proposes a theory or statement that pushes all of our minds to think hard enough, regardless if it's wrong or not, overall it's something right.
@dominicbonogofski i dont feel like thats a valid analogy, theres nothing wrong with going youre right this is a flaw and trying to adjust the rules to fix it. Maybe its just the problem with analogies is that they can also be unproveable though so its also a contradiction based on perspective 😯
this brings up a question: what if the turing machine's answer to haltability was to simply make a new rule: the turing machine cannot accept itself as an input. that would remove the proof against haltability. so does that mean mathematics could be decidable as long as it doesn't self-reference? or does this prove that set theorists were in denial? if neither, then what makes set theory different from mathematics in that in can exclude self-reference and still be useful, while mathematics/turing machines cannot?
@@daarkdocumenter@dragonsaige I had that thought as well, but then that would eliminate self-reference, which is very useful in answering a lot of questions correctly. At least, that's what my logic led to. I'm just a software engineer with a passion for maths. I could be entirely wrong.

This channel teaches the basics so easily. When explaining something such as complex numbers, they go into the most basic foundations, akin to explaining an organism from the level of quarks and gluons as opposed to the conventional educational system which just tells properties outright. Brilliant chose an awesome channel to sponsor
I never saw much of this in DiMa... most of this I picked up somewhere along the line and often in the actual CS introductory courses or while trying to understand more basic concepts using YT. Only to be distracted by that one video on the side called "The halting problem" or some such and getting curious. :D
@@Kirmeins Yeah, thing is that DM is so vast that it is really easy to set up a course that doesn't touch on any of this material. The DM course I took was like this... introduction to game theory, a little combinatorics and cryptography, coin weighing problems, stuff like that. But I think the important thing is the ability to get students interested in the material, and then they go looking for other courses that cover it.
I had this in my theoretical CS module more than the discrete maths one and while I hated the exams and the assignments, I thoroughly enjoyed getting my mind blown by such a profound topic. I've never thought that we actually would go into deeply philosophical questions about the fundamentals of logical systems, truths and math itself while studying computer science. And how it all connects to computers in the end. Brilliant video, it creates this amazing feeling of profound enlightenment I had when I first encountered this topic and I hope it reaches as many people and blow people's minds just like it had mine.
I was reading about it 2-3 months ago so I my self made some patterns.... But then it because headache..... And not after watching this video I got to know why it was a headache....
So the game of life can run the game of life but that game of life can run another game of life but is the original game of life running on another game of life?
This is the kind of brilliance that we achieve when someone asks what is the point of studying abstract Math? Turing made a machine to prove the decidability problem. That is a Big Brain move. I can't even imagine how much time and effort must have gone to make this video easy to digest. I'm truly blessed to have been a follower of your channel for years. Love you Derek.
@@guillermo.mserrano Because what the greats have found is ultimately there is a frontier of knowledge, and then you have to be satisfied living inside what might be a matrix, with no way of knowing whether you are or are not in the matrix, and without knowing if there is a higher power, if there is a purpose, etc. When you can't ask more questions of the outside world, you have to turn in, and figure out what your own meaning of life is, because you realize there might not "be a meaning". Stuff might be the way it is, because it is...
For me, the biggest takeaway of the whole thing is this: how amazingly smart must Gödel have been to come up with that proof? Obviously, every other Mathematician mentioned here is also incredibly, incomprehensibly smart, but with the other mentioned proofs, I can kind of reconstruct how one might have arrived there. But with the incompleteness theorem, I just cannot fathom how one might come up with it. The guy must have been able to just straight see the matrix.
@Markman Dave Thanks a lot bud I have been in an argument with my brother and we clearly defend different ideas, I should probably do the research on it my self. Though it’s not completely about math only partly. Where arguing about videogame strategy, where when it comes to math we usually agree, but if it comes down to different strategies were clearly on different start ups we are clearly on different opinions.
It's cods wallop. Has anyone commenting here ever studied probability? In all scientific claims you must provide the figures to back your claim. That is not done here.
@Markman Dave While it's true that groups limit one's freedom, they also expand it. If there are no other people one would be one's own input and output. This would mean we'd never get other information besides the ones already existing in one's individual system. Thus we'd be systems of stagnation. On the contrary, the more people we listen to, the more information we can get. Especially if the others have a different point of view. Thus we have a lot of contradictory Information we can work with. Or in other words: "We have an abstract horizon". With this we not only have the chance to solve the contradiction, but also a synthesis. Whether a group is beneficial or obstructing for an individual, is based on the structure of the group and the level of self-confidence of the individual. Being self-confident means to stand your ground, but also being able to reflect on the critique. Only then you can find the most differentiated solution for your time. 0nly then you can build up on the horizon of your critics and convince them.
@@SoumilSahu what is gobbledygook? - In particle physics, a lepton is an elementary particle of half-integer spin (spin 1⁄2) that does not undergo strong interactions. Two main classes of leptons exist: charged leptons (also known as the electron-like leptons or muons), and neutral leptons (better known as neutrinos). (fûr′mē-ŏn′, fĕr′-) Any of a class of particles having a spin that is half an odd integer and obeying the exclusion principle, by which no more than one identical particle may occupy the same quantum state.
I wrote an implementation of Game of Life as an A level project on a Commodore PET. I had to use machine code as BASIC was too slow. I got a bad grade compared to others in the class who wrote simple stock entry systems, as the teacher didn't understand what I was trying to do.
@@albanana683 That sounds great! If only this video was available back then, then the teacher would have definitely given you the best grade. The game of life is awesome.
I suspect that for many people, making this video might be considered a lifetime achievement. But for Derek, just one more brick in his incredible, historic castle of outstanding teaching.
@@shoam2103 Definitely. Mathematical foundations are not for the faint of heart, but when presented in this way it can become quite accessible. You don't need to be able to DO the math here in order to appreciate it or even talk about it. I haven't watched very much of this channel, and I'm going to have to remedy that.
This is fine. It's a really abstract topic that most people will never have a reason to understand to begin with. But understanding the gist of it gives you this amazing feeling of having found out something so profound and fundamental about the world that is mathematics and any system our mind creates by applying logic. It's beautiful, awe-inspiring and depressing at the same time
00:00 Undecidability is a feature of mathematics. 04:30 Not all infinities are the same size, shown by Cantor's diagonalization proof 08:28 Self-reference paradoxes in mathematics 12:18 Gödel's incompleteness theorem showed limits of formal systems in mathematics. 16:50 Gödel's incompleteness theorem shows that any mathematical system capable of fundamental arithmetic will always have statements that are true but have no proof. 21:13 Gödel's incompleteness theorem and Turing's halting problem are fundamental to modern computer history 25:10 The undecidability of the halting problem implies the undecidability of the general problem for determining whether a statement is derivable from the axioms. 29:56 The concepts and inventions of mathematicians like David Hilbert, Kurt Gödel, and Alan Turing changed the course of world events and led to modern computing devices.
There was a brief moment while reading Hofstedter's *Gödel, Escher, Bach* where I felt I truly understood the concepts... This video brought me right back to that feeling! Very well written, presented, and produced! BRAVO!
Same, but for his other book I Am A Strange Loop. In honesty, I have a feel for what the Godel proof is about, but there’s no chance I’d deduce through its formal proof.
@@ilovecomputers I felt much the same until I read David Berlinski's _The Advent of the Algorithm_. I highly recommend it; it makes the subject matter very approachable, and is a super engaging read.
WOAH WOAH WOAH!!! Let me get this perfectly straight: You comment something that is completely unrelated to the fact that I have two HAZARDOUSLY HOT girlfriends? Considering that I am the unprettiest RUclipsr worldwide, it is really incredible. Yet you did not mention it at all. I am VERY disappointed, dear te
As someone who majors in mathematics while minoring in computer science, this video is absolutely awesome. I've learned about a lot of these things in isolation, but this really connects them all.
Thanks for confirming this is solid. (I’m not quite awake; need to re-watch when I am! For what I expect will be a more spine-tingly coolness, like when I understood the RSA algorithm. ) The book “Gödel, Escher, Bach” - This remind me to read it!
This is the third or fourth time I've watched this video. I simply love it. I'm an economist myself, who used to despise the way basic algebra made economics abstruse and complicated. This was annoying because I love mathematical thinking, but not the way it was being employed in economics. Then I discovered complex systems, and everything changed. Indeed, the economy is a complex system par excellence. But then I realized that delving into the very idea behind complex systems actually helped me perfect the critique of algebra-based economics in terms of why it is futile to try to predict all outcomes. In fact, as an economist, mathematics helped me prove that math is not everything in life.
I first watched this video around when it came out. Now I am taking a final exam on logic and computability in 8 hours and I am back watching this to study. I didn't realize how much I'd learned until I realized all the topics here are familiar already. Still, it is an absolutely amazing explanation.
Same here! I watched it back then as well and today I understand those concepts from my university course in logic for computer scientists. Hope your exam went well btw :)
Listen to Alan Watts. He's more wrong than right, but that's to be expected when talking about an indescribable reality. The key to understanding lies in Eastern Philosophy. You can't grasp it, and you can't not grasp it. Those who know don't know, but those who don't know know. It comes from the knowledge of the meaning of words. Words are limited in their scope, We don't have words for metaphysical concepts, or non-conceptual realities - we can only reason within the framework of concepts, which is a something which is contrasted by a something else. Which - in a non-dualistic, non-conceptual reality means we are all very literally quite screwed, because we only deal in concepts.
everyother youtuber: animates their ideas to make it easier for the viewer vertasium: climes mountain with no context for a nice backround, spends hours making 3 words with a line through them and custom prints an entire set of cards just to express an idea, just to name a few.
@@sunnyjim1355 Uhhh... no, actually no. You, me, and a lot of other people may find it easy to understand written, objective, and scientific language, but many others don't. Some people understand artistic, subjective language easier, some others understand abstract languages easier (like the way sounds and colors relate, and "talk" to each other, like people who know how to use colors to tell a story, or people who write melodies, etc.). So probably a lot of people have a hard time with the math and stuff, and to help them have as fun as we have in this beautiful world of math, people (like veritasium) adapt the math to a more visual, artistic language. Your lack of empathy for people's different necessities helps no one, showing off you read books helps no one, belittling other people hard work helps no one. When you understand that reading books is just one of the many valid ways of acquiring information, and it doesn't make you "cooler" or "smarter", you'll definitely cringe looking back. :)
"Later generations will regard set theory a disease", "No one shall expel us from the paradise that Cantor has created" Those dudes felt *really* strong about abstract maths back then.
it's not at all surprising that they had strong feelings. they were literally debating how reality works. not just physical reality, but abstract reality too.
Seeing that "game of life" running inside "game of life" gave me goosebumps .... inception seems like child's play infront of it. The dislikes to this video are from people who are watching it sitting/standing upside down.
And I thought, well if Windows exists inside Windows due to virtualization, and you could even run deeper layers, than it doesn't surprise me, that math's followed the same logic... A paradox that is working, by self referencing itself...Which gave birth to computers...
I physically exclaimed "OH DEAR GOD" and my wife heard me from the other room and yelled "oh no, what's wrong??" It's okay, she knew what I was watching and I just shouted back "MORE MATH" and she knew what was up.

@@pottyputter05 I commented without much thought but I absolutely agree. Some (emphasis on some) of the content on RUclips is absolutely on par with Oscar nominated films, especially some of the lower budget ones
+Cheesy Boi Basically there are several mathematical proofs that mathematicians made. The bulk of these mathematical proofs is setting up an entirely new, imaginary system of math, or numbers or letters etc. In the end, it turns out that none of these systems can ever resolve the following statement: This statement is false. Because of this, any system of mathematics or language that we know how to create will always have unsolvable problems.
This video was amazing. I wanted to comment specifically, but learning Alan Turing killed himself and the circumstances surrounding that just destroyed me inside. I hope he rests in peace 😢
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.
This is pure mathematics, if students were to be taught these concepts I'm pretty sure they or most of them will lose interest, I think these topics should stick to PhD/researchers and mathematicians
@@monkelettuce1799 There's 18 million views on youtube that says that if explained properly, 18 million people can be interested in advanced mathematics. I'm about 99% positive most people viewing this don't have a PhD, or are mathematicians. I think what's great about this video is that it's not just about pure mathematics. If it was, it'd be boring, even for me. I already know about Godels incompleteness theorem. I knew a little about the history behind it, not in as much detail as is here. Instead it turns the mathematicians into real living people that have philosophical disputes with one another. When I learned math, you never really know who these people are, other than some mathematical tool you have to use, named after Euler. Even sticking some humanity and history in with mathematics makes it the most interesting. My best science teachers did that with science. I don't know why we don't do it with math.
@@monkelettuce1799 we have an optional history and philosophy of sciences class at our school where we were taught in a few lessons basically the content of this video except for the Turing part. the class is full and not even half the students attending it take advanced maths and/or physics! sure its not for everyone out there but it does interest a lot more people than u might think :) it gives context to so many concepts you and makes them more fascinating imo (and idont even like maths that much in school, physics even less). the teacher does really have to be motivated and engaging though, but that goes for most subjects
@@stevesether we do at least in my school. Perhaps the flaw is you went to the wrong school or had the wrong teachers; or here's an idea , you take responsibility for your own education and stop blaming others for what you should be reading up on.

@@HassanAhmed-rf9xr you can write a computer program that simulates every computer component (that is what is called emulation), and you can make this emulated computer run windows with the same program running in it. this is the same thing: every next level of emulation requires large amount of setup, and takes a very long time to execute. but a turning complete system is not difficult to simulate: all you truly need is a way to do if-then and store a state, everything else (operating systems, games, hardware drivers, is just built on top of having a set of instructions in the memory modifying the memory and choosing between 2 option based on the memory)
Hard agree. This is your best work. The animations, from the cartoons, to the 2D graphics, to the 3D models, were spectacular, and you and the folks that produced them deserve a huge amount of credit.
I wanted to say the same thing. This video is giving me a dopamine hit like none other. So well researched and presented. I love how he's connecting all these concepts and theorems across math, computer science, and history. What an amazing journey through time!
Same. It's been hanging there for weeks until I found the precise amount of free time in a day that I could devote to watching the video. Glad I did though.
i was doing an experiment: clicking on my recommendations and, don't paying attention to the video, but scrolling all the way down to the last video on the list of that one... I did it, 6 or 7 times and end up on this video, that called my attention. And like you, I am glad to did found it.
Woah it’s crazy that we waited for the exact same time to watch this. After just ignoring it, knowing we would watch it eventually because it’s interesting 🤔
It is my favorite math related video. The things told in the video are so concrise and fundamental I often find myself returning to this video to help me understand Math and Life
Honestly, my favourite part of him describing that part of the book is the joke. You can feel how fed up the authors were with the amount of rigor and pointless proofs. And yet, they still acknowledged that there was some level of importance to it.
Funny thing is Henry Pointcare seems to be a formalist at heart, as he claimed “later generations would have recovered from the disease” - meaning maths is Complete, Consistent and Decidable.. since he was sure that there would be a system that could with certainty disprove Canter 😏🤷♂️
even if you could you'll likely became crazy, theses logical problems are really for certain rare and random type of personalities and life environements. starting your day by deciding to solve an unsolvable puzzle and doing it seriously for science... personally i see theses fields as almost auto mutilation.
@@wassuprocker892 That's where the fun is. Basically life itself is a paradox. Escaping the loop is freeing, but you strip yourself of fun, while staying in it keeps the fun there. Simple solution to the paradox of life is our free will. We can make a choice whether to stay or leave. :) Edit: "Fun" was kind of the wrong word. Satisfaction/pleasure is a better one I think.
Seriously. The topics he presents are all well covered on youtube and in textbooks, but Veritasium manages to present it so elegantly. It makes it so interesting for topics that can sometimes be boring to a lot of people.
This is so beautiful! Thanks for being one of the people that helped me truly discover mathematics. I grew up hating math, but thanks to mathematicians, physicist, computer scientists and programmers here on youtube i have grown to really love and appreciate the subject.
My first instinct would be to assume that the battle between Intuitionists and Formalists couldn't have been that dramatic. But then I remembered that there was an actual riot featuring thrown chairs and fistfights on opening night of Stravinsky's Rite of Spring over the timbre of the bassoonist. Man, nerds back in the day were hardcore.
Reading this really depresses me, how far we've fallen as a civilization. Look what we used to fight for, the greek requirements and essays about Virgilio just to enter universities, the academic debates in the common tongue, intelligence as something more than an industrialized misconception of public education ("nerds"), our music sensibility, etc. The idiots took over (I know, I'm one of them), the grandchildren of the Revolution, the City of Men, Rome.
The fighting on the opening night of Rite of Spring was about much more. It is a very visceral work. It features a very unconventional choreography, with violent and sexually suggestive movements (far from a more traditional ballet, like the Swan Lake). The music itself is rather dissonant, and uncommon for the time. And, on top, it's about the ritual sacrifice of a virgin. Groundbreaking and controversial art always generate strong reactions; against and in favor. I would totally fist fight someone over the rite of spring. It's so riot worthy. And I think it's great if people are passionate about things and are willing to take stuff like music or math this seriously.

@@thefran901 you can even program the game of life to play musical notes and it makes quite an interesting random pattern/note generators. It’s one the of the few random generation algorithms that can make interesting music while not needing to combine separate algorithms for pitch and time based randomization to be musical. And it generally plays music in a way that is like someone purely improv noodling vs something that sounds either too random or too mechanical.
It is important to note that in the "incompleteness theorem" that even though it is possible to create a "well formed" statement within the context of a specific axiom system, that may not be provable within that axiom system, it does not preclude proving or disproving the statement in a "larger" axiom system . Some problems formulated in the context of geometry may not be provable with axioms of geometry, but may be provable in the context of algebraic geometry.
A similar question to this was asked in my Foundations of Computer Theory course in my Master's degree. I don't remember the question itself but I solved it using contradiction of two self referencing black boxes (this video had 1). And I got 99.4% on that test, probably I was first in the class.
@@Digital-Dan lol. Well it was the final exam and there were no classes scheduled later, otherwise I would have found out. Or if I had emailed the professor but he may have denied my request. I would say it's more likely it's me than not as it was a very difficult test and my professor Aaron Deever (who was at Cornell) is known to create his own homework questions and his own tests from scratch. Also I did ask a bunch of guys from my batch and none of them had heard anyone getting as much as my percentage.
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.
This feels like the start of a new era for Veritasium. The production value is off the charts! And the topic is just beautiful. Congrats Derek and team S2

See I don't like it. Theoretical mathematical truths that aren't provable and/or practical are just neat to hear and that's it. It doesn't have a purpose. That's what I don't like. You can make up a story about a hotel with infinite rooms or tell me that there's an infinite number of twin prime numbers but do something with it. Show me an example on why it's worth knowing. This is what I'm talking about at 20:59. It's a paradox. Those can be neat. What did you do with the information though? What *can* you do with that information? I would MUCH rather Veritasium cover content like where he went into public and asked people things like, "Why does the earth rotate?" or "Why do two objects fall at the same speed?" but that's just my personal preference. I'm happy so many people like where his channel is going. I wish I was one of those people.
I had to watch this video twice over a two-day period to comprehend Canter’s diagonal proof. Thank you again Veritasium for explaining complex math and science in layman’s terms.

Wow, can we just appreciate the production value of this video?

I seriously doubt that "Corrupter of the Youth" was intended as an insult. It was the same charge brought against Socrates, something all scientists back then would know intimately. I think it was meant more to imply that Set Theory had sparked an irrational and emotionally motivated pushback. And that it was as revolutionary as Socrates' teachings.
"...thinking about this problem transformed the concept of infinity, changed the course of a world war, and led directly to the invention of the device you're watching this on right now" i've seen a bunch of videos on this subject, but none as motivating and captivating as this. derek really illustrates the difference that good storytelling can have.
It is truly a gigantic field. Most maps of mathematics stop short of the connections between the fields it lists; let alone all the unique problems in the fields and what they’d imply if they are or aren’t true.
I know right, seeing that literally brought tears to my eyes, so beautiful. Seeing that I realised I had never quite grasped the full extent of Turing-Completeness - any Turing-Complete system can simulate itself, using only itself to do so.
I am just a High school Algebra 2/Trig student, I really want to learn science and math but it's all such a vast world, one of the reasons I also tear up. However, my question remains: Is it possible to play doom in the Game of Life?
Actually no, Hilbert didn't proved everything, he created a system of proofs, a formal way to prove everything in mathematics and every other field. On the other way, Gödel didn't want to disproof all mathematics, he proved that not ALL mathematical statement can be proven, that is, there will be always some true statement that we will not be able to prove, but still there will be mathematical statements that CAN be proven, till this day we prove new and old mathematical laws, the problem is we can't know which statement can be proved or not, we might not find the answer right now and say that it is unprovable and 500 years later someone prove it, it is just undecidable, that's the point of Gödel's study.
And in Stat I learned about "we fail to reject the null hypothesis. We do not accept the null hypothesis, we just fail to reject it because we don't have enough evidence."
I’m gonna go to my math teacher and be like “math is incomplete and inconsistent,” and she’s gonna say no it is and then I will now more about math than her and I will be so happy
I’ve just finished a 3 month university mathematics module on Gödels theorems and you have managed to summarise the whole thing in impressive detail in just 30 minutes. Well done sir.
@@pinklady7184 I haven’t read too many books as my modules are all self-contained. However all my modules have optional reading lists and I’d be happy to tell you what they are if you choose a subject area. My modules have all been in pure mathematics (logic, analysis, algebra, number theory etc.) so it would have to be in that area. I could even ask my lecturers for recommendations if you like :)
Anil Vips First off, I am a traditional artist with a growing interest in 3D realism & animation including physics simulations, which require lots & lots of writing maths inside node compositing & scripts. I am only intermediate in mathematics. I am not in college, but I can self-study at home, no problem. Only two years ago, I took up studying mathematics at home, as I had needed it for 3D realism, also for programming & scripting. Also, I have just recently taken up physics and engineering as well. I study those a little and maths more. Initially, two years ago, I had to relearn highschool maths at home as I had forgotten half of it. After having learned them off, I moved onto reading undergraduate books on calculus, analysis, linear algebra, set theory, number theory, abstract algebra, discrete mathematics, etc. I know just roughly 75% of them. I don’t know what other undergraduate maths I am missing on the list. Well, I will get there anyhow. At home, I have roughly 25 paper books in my collection, those on maths & physics. Half that number in Kindle. Of paper books, I have only one on calculus (metric version) by Ian Stewart, and I don’t know what next calculus books to read after that. Three books on linear algebra. One on discrete mathematics. One on vectors and tensors by Dan Fleisch. One on algebraic number theory. I’m always curious to know what books that undergraduate students read in college, especially in their first year & second year, and what they read thereafter. I understand just a little of topology, but I don’t know what prerequisites to study before moving to topology, category theory, and suchlikes. I regularly go exploring their internal topics inside Wikipedia, Mathematics Stackoverflow, MathOverflow, Quora, etc. I read what others are studying in colleges, what books they read for studies.
Hasan Tınaz Been there and done that. New maths is always a struggle. It is one step at a time. I treat each information like a gold nugget. Gather them and clump all the gold nuggets together and that is a gold bar, which is knowledge. Many gold bars gathered - a talent. I oftentimes learn math by brain-picking nerds social media like Twitter, Quora, Facebook groups, etc.

He failed... I mean... I've heard Hilbert's name propably a thousand times but this video felt like the first time I heard about Gödel. And I'm from Germany... :D
@@Kirmeins even if you're only studying mathematics, you won't really hear Gödel's name until final year of undergraduate study at the earliest, unless you do an awful lot of advanced reading. Hilbert, on the other hand, has his name scattered throughout undergraduate and graduate topics in mathematics and physics. Gödel's work is considered fairly esoteric and difficult, while Hilbert is more spread out. So it's not surprising that you wouldn't have heard of Gödel if you haven't touched on foundations of maths.
I watched this video 3 years ago, fell in love with math and now I started my bachelor's program in computer science. The term social media influencer must be defined by people like you.
I'm glad I was an engineer. I learnt to use advanced mathematics to build things but I never had to worry about this stuff thank goodness. I think it's kept me sane.
same here except synthetic chemist here lmao. I love thinking about maths and I have a pretty good understanding of math concepts and "weird" things like quantum field theory and relativity, above average for a chemist, but it's more of a hobby for me. Like a curiosity that I enjoy sometimes thinking about. Not something that gets me upset when it doesn't work out, like synthesis procedures do when they don't work out. That thing can get on my nerves when I spend months tweaking the same reaction to no avail.

@@reggiecortez2485 Good luck my friend.....It isn't easy....Some have an innate affinity for math...others have to 'beat it into themselves'....But It can be done. My best advice would be to learn how to write out longform, so you can check your work, and to find an instructor that can break components down into digestible bites for you. As an aside, if you don't mind, what part do you have the most difficulties with? I found algebra boring...geometry interesting...and once I was interested in geometry the algebra and how it applied was no longer 'boring'. That in turn led to trig and calculus. Latch on to what interests you and turn that into a strength....It will help unlock other facets.
@@reggiecortez2485 I think with Math, review is everything. Take simple classes for fun, they will add much needed clarity to the classes you've once flunked out of when you retake them.

You just need to get a much deeper understanding and I can promise that you will be the better for it (for the deeper understandings)

This comment deserves more likes

Woah...
You nailed this comment
This comment is just too good
As a mathematician I haven't seen a more elegent presentation of these concepts,especially Godel's theorem. Amazing job thank you.
I just don't understand where equation g came from. Why would it have been a contradiction to prove g, just because it said "this can't be proven"? If one had proven it anyways, Gödel's statement would have been wrong, yes,but what of it? Why did he write "this can't be proven"? Purposefully trying to MAKE a paradox by setting contradicting rules and then saying "See? Major problem, math incomplete." doesn't make any sense to me. If things naturally contradict, isn't it the axiom's fault? Shouldn't we just rethink the basics?
@@WritersMoment well if he didnt do that contradiction then we wouldnt know the completeness of math
@@WritersMoment I didn't watch the video, so I don't know how they explained it, quite possibly very incorrect. However the point of the 2nd Gödel incompleteness theorem is if your axioms fulfill a bunch of desirable attributes (such as being able to prove all true statements about the natural numbers), then you can encode its own consistency. Those are known as Gödel sentences. As the axiom system can not prove that, it's therefore not complete if it's consistent. It's possible for an axiom system to not have arithmetic, but be complete and consistent, have arithmetic, be complete but not consistent or be consistent, have arithmetic but not be complete.
So it's not possible to rethink the basics to get all desirable quantities. Math is not flawed tho, since having arithmetics and a consistent axiom system is possible and absolutely sufficient for everything that mathematicians do.

It's like a kid on a playground saying they weren't playing when someone else tags them.
@dominicbonogofski i dont feel like thats a valid analogy, theres nothing wrong with going youre right this is a flaw and trying to adjust the rules to fix it. Maybe its just the problem with analogies is that they can also be unproveable though so its also a contradiction based on perspective 😯
@@EonsEternity I was just implying that it had the same energy behind it.
this brings up a question: what if the turing machine's answer to haltability was to simply make a new rule: the turing machine cannot accept itself as an input. that would remove the proof against haltability. so does that mean mathematics could be decidable as long as it doesn't self-reference? or does this prove that set theorists were in denial? if neither, then what makes set theory different from mathematics in that in can exclude self-reference and still be useful, while mathematics/turing machines cannot?
@@daarkdocumenter@dragonsaige I had that thought as well, but then that would eliminate self-reference, which is very useful in answering a lot of questions correctly. At least, that's what my logic led to. I'm just a software engineer with a passion for maths. I could be entirely wrong.

But I think the important thing is the ability to get students interested in the material, and then they go looking for other courses that cover it.
I agree, this is also the key for appreciating the role of AI/ML theory. And randomised algorithms.
I had this in my theoretical CS module more than the discrete maths one and while I hated the exams and the assignments, I thoroughly enjoyed getting my mind blown by such a profound topic. I've never thought that we actually would go into deeply philosophical questions about the fundamentals of logical systems, truths and math itself while studying computer science.

For me, the biggest takeaway of the whole thing is this: how amazingly smart must Gödel have been to come up with that proof?

@@ValMartinIreland Are you referring to the video? Or the comment? Or someone’s reply to the comment?
@Markman Dave While it's true that groups limit one's freedom, they also expand it. If there are no other people one would be one's own input and output. This would mean we'd never get other information besides the ones already existing in one's individual system. Thus we'd be systems of stagnation. On the contrary, the more people we listen to, the more information we can get. Especially if the others have a different point of view. Thus we have a lot of contradictory Information we can work with. Or in other words: "We have an abstract horizon". With this we not only have the chance to solve the contradiction, but also a synthesis.
Whether a group is beneficial or obstructing for an individual, is based on the structure of the group and the level of self-confidence of the individual. Being self-confident means to stand your ground, but also being able to reflect on the critique. Only then you can find the most differentiated solution for your time. 0nly then you can build up on the horizon of your critics and convince them.

Hey, I'm the literal opposite of you! (Majored in CS, minored in Maths.)
This is the third or fourth time I've watched this video. I simply love it. I'm an economist myself, who used to despise the way basic algebra made economics abstruse and complicated. This was annoying because I love mathematical thinking, but not the way it was being employed in economics. Then I discovered complex systems, and everything changed. Indeed, the economy is a complex system par excellence. But then I realized that delving into the very idea behind complex systems actually helped me perfect the critique of algebra-based economics in terms of why it is futile to try to predict all outcomes. In fact, as an economist, mathematics helped me prove that math is not everything in life.
I first watched this video around when it came out. Now I am taking a final exam on logic and computability in 8 hours and I am back watching this to study. I didn't realize how much I'd learned until I realized all the topics here are familiar already. Still, it is an absolutely amazing explanation.
Same here! I watched it back then as well and today I understand those concepts from my university course in logic for computer scientists. Hope your exam went well btw :)
Listen to Alan Watts. He's more wrong than right, but that's to be expected when talking about an indescribable reality. The key to understanding lies in Eastern Philosophy. You can't grasp it, and you can't not grasp it. Those who know don't know, but those who don't know know. It comes from the knowledge of the meaning of words. Words are limited in their scope, We don't have words for metaphysical concepts, or non-conceptual realities - we can only reason within the framework of concepts, which is a something which is contrasted by a something else. Which - in a non-dualistic, non-conceptual reality means we are all very literally quite screwed, because we only deal in concepts.

@@sunnyjim1355 Uhhh... no, actually no. You, me, and a lot of other people may find it easy to understand written, objective, and scientific language, but many others don't. Some people understand artistic, subjective language easier, some others understand abstract languages easier (like the way sounds and colors relate, and "talk" to each other, like people who know how to use colors to tell a story, or people who write melodies, etc.). So probably a lot of people have a hard time with the math and stuff, and to help them have as fun as we have in this beautiful world of math, people (like veritasium) adapt the math to a more visual, artistic language.
Your lack of empathy for people's different necessities helps no one, showing off you read books helps no one, belittling other people hard work helps no one. When you understand that reading books is just one of the many valid ways of acquiring information, and it doesn't make you "cooler" or "smarter", you'll definitely cringe looking back.

And I thought, well if Windows exists inside Windows due to virtualization, and you could even run deeper layers, than it doesn't surprise me, that math's followed the same logic... A paradox that is working, by self referencing itself...Which gave birth to computers...

Because of this, any system of mathematics or language that we know how to create will always have unsolvable problems.

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.
This is pure mathematics, if students were to be taught these concepts I'm pretty sure they or most of them will lose interest, I think these topics should stick to PhD/researchers and mathematicians
@@monkelettuce1799 There's 18 million views on youtube that says that if explained properly, 18 million people can be interested in advanced mathematics. I'm about 99% positive most people viewing this don't have a PhD, or are mathematicians.
I think what's great about this video is that it's not just about pure mathematics. If it was, it'd be boring, even for me. I already know about Godels incompleteness theorem. I knew a little about the history behind it, not in as much detail as is here.
Instead it turns the mathematicians into real living people that have philosophical disputes with one another. When I learned math, you never really know who these people are, other than some mathematical tool you have to use, named after Euler. Even sticking some humanity and history in with mathematics makes it the most interesting. My best science teachers did that with science. I don't know why we don't do it with math.
@@monkelettuce1799 we have an optional history and philosophy of sciences class at our school where we were taught in a few lessons basically the content of this video except for the Turing part. the class is full and not even half the students attending it take advanced maths and/or physics! sure its not for everyone out there but it does interest a lot more people than u might think :) it gives context to so many concepts you and makes them more fascinating imo (and idont even like maths that much in school, physics even less). the teacher does really have to be motivated and engaging though, but that goes for most subjects
@@stevesether we do at least in my school. Perhaps the flaw is you went to the wrong school or had the wrong teachers; or here's an idea , you take responsibility for your own education and stop blaming others for what you should be reading up on.

@@HassanAhmed-rf9xr you can write a computer program that simulates every computer component (that is what is called emulation), and you can make this emulated computer run windows with the same program running in it. this is the same thing: every next level of emulation requires large amount of setup, and takes a very long time to execute.
but a turning complete system is not difficult to simulate: all you truly need is a way to do if-then and store a state, everything else (operating systems, games, hardware drivers, is just built on top of having a set of instructions in the memory modifying the memory and choosing between 2 option based on the memory)

Thanks for being one of the people that helped me truly discover mathematics.
I grew up hating math, but thanks to mathematicians, physicist, computer scientists and programmers here on youtube i have grown to really love and appreciate the subject.
My first instinct would be to assume that the battle between Intuitionists and Formalists couldn't have been that dramatic. But then I remembered that there was an actual riot featuring thrown chairs and fistfights on opening night of Stravinsky's Rite of Spring over the timbre of the bassoonist. Man, nerds back in the day were hardcore.
They still are. It's just harder to hide a murder
Reading this really depresses me, how far we've fallen as a civilization. Look what we used to fight for, the greek requirements and essays about Virgilio just to enter universities, the academic debates in the common tongue, intelligence as something more than an industrialized misconception of public education ("nerds"), our music sensibility, etc. The idiots took over (I know, I'm one of them), the grandchildren of the Revolution, the City of Men, Rome.
The fighting on the opening night of Rite of Spring was about much more. It is a very visceral work. It features a very unconventional choreography, with violent and sexually suggestive movements (far from a more traditional ballet, like the Swan Lake). The music itself is rather dissonant, and uncommon for the time. And, on top, it's about the ritual sacrifice of a virgin.
Groundbreaking and controversial art always generate strong reactions; against and in favor.
I would totally fist fight someone over the rite of spring. It's so riot worthy.
And I think it's great if people are passionate about things and are willing to take stuff like music or math this seriously.

@@thefran901 you can even program the game of life to play musical notes and it makes quite an interesting random pattern/note generators. It’s one the of the few random generation algorithms that can make interesting music while not needing to combine separate algorithms for pitch and time based randomization to be musical. And it generally plays music in a way that is like someone purely improv noodling vs something that sounds either too random or too mechanical.
It is important to note that in the "incompleteness theorem" that even though it is possible to create a "well formed" statement within the context of a specific axiom system, that may not be provable within that axiom system, it does not preclude proving or disproving the statement in a "larger" axiom system .
Some problems formulated in the context of geometry may not be provable with axioms of geometry, but may be provable in the context of algebraic geometry.

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.

I seriously doubt that "Corrupter of the Youth" was intended as an insult. It was the same charge brought against Socrates, something all scientists back then would know intimately. I think it was meant more to imply that Set Theory had sparked an irrational and emotionally motivated pushback. And that it was as revolutionary as Socrates' teachings.
Or maybe they had other reasons to think that the conclusions the theorem implicated were wrong, which ultimately were.
"...thinking about this problem transformed the concept of infinity, changed the course of a world war, and led directly to the invention of the device you're watching this on right now" i've seen a bunch of videos on this subject, but none as motivating and captivating as this. derek really illustrates the difference that good storytelling can have.

What math books have you read this year and last few years? I am curious as I am mostly self-studying maths.
@@pinklady7184 I haven’t read too many books as my modules are all self-contained. However all my modules have optional reading lists and I’d be happy to tell you what they are if you choose a subject area. My modules have all been in pure mathematics (logic, analysis, algebra, number theory etc.) so it would have to be in that area. I could even ask my lecturers for recommendations if you like :)
Anil Vips First off, I am a traditional artist with a growing interest in 3D realism & animation including physics simulations, which require lots & lots of writing maths inside node compositing & scripts. I am only intermediate in mathematics. I am not in college, but I can self-study at home, no problem.
Only two years ago, I took up studying mathematics at home, as I had needed it for 3D realism, also for programming & scripting. Also, I have just recently taken up physics and engineering as well. I study those a little and maths more.
Initially, two years ago, I had to relearn highschool maths at home as I had forgotten half of it. After having learned them off, I moved onto reading undergraduate books on calculus, analysis, linear algebra, set theory, number theory, abstract algebra, discrete mathematics, etc. I know just roughly 75% of them. I don’t know what other undergraduate maths I am missing on the list. Well, I will get there anyhow.
At home, I have roughly 25 paper books in my collection, those on maths & physics. Half that number in Kindle.
Of paper books, I have only one on calculus (metric version) by Ian Stewart, and I don’t know what next calculus books to read after that. Three books on linear algebra. One on discrete mathematics. One on vectors and tensors by Dan Fleisch. One on algebraic number theory.
I’m always curious to know what books that undergraduate students read in college, especially in their first year & second year, and what they read thereafter.
I understand just a little of topology, but I don’t know what prerequisites to study before moving to topology, category theory, and suchlikes. I regularly go exploring their internal topics inside Wikipedia, Mathematics Stackoverflow, MathOverflow, Quora, etc. I read what others are studying in colleges, what books they read for studies.
Hasan Tınaz Been there and done that. New maths is always a struggle. It is one step at a time. I treat each information like a gold nugget. Gather them and clump all the gold nuggets together and that is a gold bar, which is knowledge. Many gold bars gathered - a talent. I oftentimes learn math by brain-picking nerds social media like Twitter, Quora, Facebook groups, etc.
Hasan Tınaz I keep a study diary on all the tutorial videos that I watch in RUclips, Udemy, etc. A study diary hugely helps.
FYI: Numberphile has some nice interviews with John Conway, discussing a bunch of things including his Game of Life
What if there's a copy of the Game of Life out there which is him, represented.
When he showed "It's the Game of Life... running on the Game of Life" it literally blew my mind.
Can someone explain that better? It was cool but I think I don't fully comprehend what is happening
@@ritwikism he put an input in the game of life that it's output, instead of random patterns, was the game of life itself.
@@ritwikism they basically built a computer on the game of life that runs the game of life
@@ritwikism Since the Game of Life is Turing complete, that means you can essentially program anything with the Game of Life. At 29:50 they zoomed out to show how someone had programmed the Game of Life inside of the Game of Life.
The idea is somewhat similar to simulating a computer on a computer, like a macbook running a virtual machine of that same type of macbook.
@@cookiecan10 hence going back to Derek's first answer: Life. If life is turing complete (which it must be), there must be a way to fully simulate itself
The best video I have ever watch hands down. Thank you!
mom: why did you get a B in math!
me: math has a fatal flaw
B is good
@@cohensmith6100 and A is excellent.
@@ALBINO1D ya but like why get mad abt a b when most mfs fail math
@@cohensmith6100 is your benchmark just to be better than worst, or to be the best?
Learn a lesson from Ash Ketchum.
@@ALBINO1D Hes like over 20 and hangs with 12 yrs old girls ill pass man
This was not a youtube video. This was a documentary. Loved it.
love it when that happens
as a cs student it feels like this video should be called "the origins of computer science"
@@carpetperson5685 the origins of computer science sounds like an essay no offense. It really only fits the second half of the video. I’m kinda mean ngl, sorry
It was an experience.
Godel really woke up and said "i'm gonna ruin this man's whole career".
He failed... I mean... I've heard Hilbert's name propably a thousand times but this video felt like the first time I heard about Gödel. And I'm from Germany... :D
@@Kirmeins its a joke my dude
That's probably because you're from Germany and Hillbert was german. I'm from Austria and I heared about Gödel way earlier and lot more than Hillbert.
Gödel could have nuked the basis of formal logic, for all I understand.
@@Kirmeins even if you're only studying mathematics, you won't really hear Gödel's name until final year of undergraduate study at the earliest, unless you do an awful lot of advanced reading. Hilbert, on the other hand, has his name scattered throughout undergraduate and graduate topics in mathematics and physics. Gödel's work is considered fairly esoteric and difficult, while Hilbert is more spread out. So it's not surprising that you wouldn't have heard of Gödel if you haven't touched on foundations of maths.
I watched this video 3 years ago, fell in love with math and now I started my bachelor's program in computer science. The term social media influencer must be defined by people like you.
I can’t decide if I’m smarter or dumber after watching this.
The smarter you are, the less you know
@@cjc722 The smarter you are, the more you know. But the smarter you are, you know that you know less.
@@YavNe This is at the core of the Dunning-Krugereffect.
You are both, that's the lesson 😉
Both; it's a paradox.
I'm glad I was an engineer. I learnt to use advanced mathematics to build things but I never had to worry about this stuff thank goodness. I think it's kept me sane.
YKW‘s glad he‘s an engineer aswell..but Holland
same here except synthetic chemist here lmao. I love thinking about maths and I have a pretty good understanding of math concepts and "weird" things like quantum field theory and relativity, above average for a chemist, but it's more of a hobby for me. Like a curiosity that I enjoy sometimes thinking about. Not something that gets me upset when it doesn't work out, like synthesis procedures do when they don't work out. That thing can get on my nerves when I spend months tweaking the same reaction to no avail.
I just flunked out of engineering school and the engineering school said I failed math so many times that I can no longer major in anything involving math at that school, so as a middle finger to them I'm out at Community College to get my Math degree, wish me luck 🙃
@@reggiecortez2485 Good luck my friend.....It isn't easy....Some have an innate affinity for math...others have to 'beat it into themselves'....But It can be done. My best advice would be to learn how to write out longform, so you can check your work, and to find an instructor that can break components down into digestible bites for you.
As an aside, if you don't mind, what part do you have the most difficulties with? I found algebra boring...geometry interesting...and once I was interested in geometry the algebra and how it applied was no longer 'boring'. That in turn led to trig and calculus. Latch on to what interests you and turn that into a strength....It will help unlock other facets.
@@reggiecortez2485 I think with Math, review is everything. Take simple classes for fun, they will add much needed clarity to the classes you've once flunked out of when you retake them. Don't hurry because you're competing with your contemporaries; the math is always there. You just need to get a much deeper understanding and I can promise that you will be the better for it (for the deeper understandings)
"How about you just hire another barber?" Said the engineer
And you only need two barbers to break the paradox. They can shave each other; the rules never said that wasn't allowed.
Engineering student here, my first thought as well
2 barbers 1 town
@@jeffirwin7862 IYKYK
@@theknightwhosayn1 only the barber can shave anyone, that was one of the rules
Amazing video!
I’m not able to understand it fully obviously, but the ideas are presented in such a way that’s so clear and precise yet easy to understand. Veritasium is incredible!
I like the first title tbh. "There is a hole at the bottom of math" sounds wayy more interesting. I just wish youtubers experimented with abstract titles like that, but it changed to something much more bland and clickbaity. Like I get it, just a little sad tho.
That wasn't even the first title. The first one was "You can't prove everything thats true". I think Derek is changing to to test different title strategies.
@Angelspawn I would say that "Fatal flaw" is clickbait. The facts in this video will never kill math lol.
@@kaynex1039 it is a fatal flaw, because once you think about it, everything you do in maths is being questioned by my brain
"hole at the bottom of math" like we all do, math too 🤣 may be for decency purpose he changed it.
@@NM-zb6pd And changing from the first title "You can't prove everything that's true" may also be for decency purposes, as it's indecent for scientists to touch anything close to religion, to treat religion as they were one's private parts.
