/sci/ - Science & Math

what happened?

>>12029049
Yes, it isn't

>>12029049
what did he do? i saw a few of his vids and thought he did one of the better jobs out there. like as bearable as pop shit gets as he does actually go over the math albeit in the most introductory way.

his videos about linear algebra are pretty well designed

>the kutrzgesagt shill is back

>>12029074
>>the kutrzgesagt shill is back
what?

>>12029069
this. I haven't really watched his other content, but the linear algebra series helped with the intuition.

His video about blockchain was pretty based. Made me finally understand what's going on there.

>>12029049
Don't know what you mean op, his new video seems alright
Or are you buttblasted because he did the video because of that weird youtube math shit?

>>12029077
some fan or the writer himself shills here occasionally. It's a shit channel with shit content. total pseud garbage with fancy animation and a voice actor to make it look good

>>12029049
His videos are pretty good. Sounds like you're mad because he makes math accessible to normies.

He’s an insufferable faggot but his animations are top notch

>>12029049
I implemented neural networks from scratch to classify mnist, just by following his videos. Also understood and implemented fourier transform thanks to him.
So he understands and transfers the knowledge pretty well.

More like
>the very basics of a topic using as little math as possible acompanied with pretty animations thus avoiding the real thing and all it's difficulty, giving you the impression that you learned something while nothing of substance was actually said but instead some barely usefull facts with watever else had a good demonstration/show off and so you will eventually forget everything about it in 2~3 months
Yes, it is purely entertainment using math like a magic show. This is as much popsci as it gets. To be fair his videos are quite suitable for his target audience (people who haven't seen math since high-school and are never going to do math in their lives again). The real problem behind popsci is the attitude of the average person towards science and math. Everyone "loves" them but the average person finds them too dificult. They want to take part in them, it is considered high status by society to be involved in them this makes most people only care superficially about math, they care for the sake of caring, to be "cool". So they prefere to only see some "beautiful" results without any mention to the "boring" math behind it. How can something beautiful come out of something boring? The answer is that it's neither, it's just math, both are math. That would mean that the average person doesn't like math but that is something they will never admit because they are conditioned by society to "love" science and math. How can they not when it has improved our lives so much? Ted Kazynski would disagree but it doesn't matter to what extend it is true, it's in peoples heads. By stating they don't like math or science they would deny the foundation of modern society, a society based on the archetype of the weak victimised yet somehow smart nerd who while bullied unfairly and unable to deal with it will succeed later in life (they never do)

his only bad video is on Bayes theorem, because he (like all IFLM nerds) is a Bayesian taliban that thinks it explains away the problem of inference in probability. But ignoring that part, its a good entry level statistics video. And his video on Fourier actually gave me a new perspective that i wasnt aware of.

>>12031370
Can you go a bit more in depth on why he didn’t cover the bayes theorem properly?

>>12030553
>projecting
In case you didn't catch it the reason you forget his content it is written just above it. He shows some cool things and never goes into the how it's done part, if he does he does it very superficialy and omits many things. Do you remember a video of his from last year? If you do can you shortly present the topic? If not you haven't learned.

>>12031288
>Not even gonna read your blog post. Stop being so mad at something objectively beneficial.
If you had read my post you would have understood that I am not angry. If you had read my post you would understand that it is only beneficial to those who want to satisfy their psychological needs of being "cool" and smart. The fact that you think this is somehow objectively beneficial tells me that you get those needs of yours satisfied by him and thus you reject any critisism in anger.
>you dumb angry cunt
Who is angry here? This is indeed a projection.

>>12031343
Thanks for contributing to the discussion with valid arguments. Now read my post.

>>12031721

>>12031721
>>12030526
you sound like that one professor who makes his course as dry and as incomphrenesible as possible on purpose because "I didn't have it easy, so nobody should have it easy"

>>12031844
lol ok sure

>>12031892
My only posts are >>12030526 and >>12031721

>>12031974
It's not about having it easy, in popsci you don't have it at all. You are only shown some basic things and some results in order to impress you and make you feel smart, no learning takes place. As I said, I bet none of his viewers remember the topic of his videos 1 year ago and certainly no one can talk about them. Maybe you will understand when you encounter the same topics in college and maybe you will see how much he simply doesn't present or why you can't learn from his videos.

>>12031721
>satisfy their psychological needs of being "cool" and smart.
No one watches a math video on youtube and thinks their cool. I'd also suggest it's a stretch to think "wow I'm smart" after watching a math video. I think you're projecting and your criticisms are wildly misplaced

>>12029069
this. I hate anything pop, but his linear algebra videos are good. I wonder if I ever would have done that by myself, which I say, Yes because I am also doing computer graphics and it would have take me long to experiment and understand concept of determinant, scaling, mulitplications, linear combination etc but then I think real Algebraist already have this intuition without looking at stills or animation and I realise I am low IQ < 100 subhuman.

>>12030526
Yes his channel is dangerous and promote virtue signalling using maths. The retarded comments and number of likes tells you that. He should shut down his channel and instead publish papers for greater good.

>>12031721
Yes he should have a Mixim tutorial playlist where he explains how he himself understood those concepts.

>>12032567
>No one watches a math video on youtube and thinks their cool
Indeed, what I'm saying is that in society mathematicians and scientists are considered high status. People who are interested in math are considered inteligent and therefore "good". What I meant by the need to feel "cool" was the need to be a high status member of society, which is satisfied by those videos who treat the viewer like he has the ability not only to understand these concepts without the required math background but also like he can ask and answer complicated questions regarding them. In reality the questions asked and answered are always the most trivial of the topic. This also gives the viewer a false sence of intelligence making him believe he is smart even when he passively watches. This also satisfies the viewers need to have positive traits. This anon here >>12032640 >>12032646 gets it.

>>12030526
So basically
>people only "love math" to seem cool
>therefore they only know the "beautiful" results and have a surface level understanding of the subject
>an average person can't possibly take a deep dive into the "boring" parts of math and misses a huge part of mathematics
>therefore popsci and popmath is detrimental to math

3b1b is the most talented 'lecturer' on yt. I suspect you are a bitter contrarian that doesn't have the empathy to understand what a difference he's made in making concepts like machine learning and linear algebra palatable to the masses

>>12029049
lmao
Imagine feeling threatened that people learn new things with well made content
That's probably the degree 0 of intelligence.

>>12029049
He has literally done complete mathematical proofs on video so that's a real as you can get. You are probably talking about his most recent video though but I think that for every full proof video he gets a pass for a less tight general knowledge video. Especially given the fact that it would be impossible to take people from the axioms of group theory all the way up to the proof of the existence and uniqueness of the monster in a video or even a series of videos unless he dedicated the next years of his life to it.

>>12032761
pretty sure >>12032640 is being sarcastic, also pretty you're an angry projecting autist

>>12033706
>He has literally done complete mathematical proofs on video so that's a real as you can get
Which video(s) does he present rigorous proofs for the concepts he discusses?

>>12033835
He has a complete proof of the Wallis product formula. Not to mention that in videos in which he skims some details he links to complete proofs.

>>12033855
>a complete proof of a curiosity
Good to know.

I could also link to wikipedia which contains proofs every time I explain basic calculus concepts to retards in /sqt/ does that make me a responsible and beneficent educator of the public or is the lack of the "geometrically intuitive" animations and birdlike homosexual voice disqualify me? Do I need a patreon and to appear at talks at Pajeet universities as well?

>>12033810
>no u
sarcastic of not, the point remains

>>12033866
Why are you so mad at this? Dude's just making cute math animations. What even is your point? That he shouldn't?

>>12033918
The guy literally posts paragraphs, explaining his opinion about 3b1b, while you lots calling him autistic hater
now you're asking what is your point?! lmao

>>12033951
The paragraphs he posted basically boils down to:
it's not real math because it's not dull and boring and it makes people feel smart (which is a bad thing because I said so)

Basically the opinion of someone who considers himself smarter than everyone, yet feels threatened when other people might learn a trick or two.

>>12029049
His videos remind me of my favorite professor in the math department at my university. Pretty enjoyable content.

>>12033971
You won’t learn any tricks from his videos. Spivak, Arnold, Cramer will teach you tricks. Feynman will teach you tricks. But, you won’t even learn how to rotate objects or analyze the asymptotic behavior of a function from those videos. You won’t learn any sneaky factorization or algebra tricks, you won’t learn any interesting substitutions, you won’t even learn how by to abuse orthogonality or the triangle inequality or how to use geometry to solve analytical problems. No, you won’t learn anything at all worth your time but you will learn how to listen and accept other people’s understanding of maths as god given.

>>12034021
People learn intuitive ways of solving or thinking about some problems from his videos, which is crucial to do any Mathematics.
You won't admit it because you think of yourself above all that and have negative priors deeply embedded in your thick skull.
Even if what you said was right, wasting your time criticizing the way people waste their time on youtube is the lowest form of intelligence you could ever display.

Take comfort in the fact that you're still anonymous.

No they really don't. You only learn by doing and by being encouraged to do by people that have mastered the subject. He hasn't mastered any topics of mathematics, he didn't even get a PhD or contribute any research of worth.

Consider it a primer, a poster for those interested in attending the full thing. Its not just a commercial but it also gives context to further information on the topic, context which is required for people to learn at all.

>>12035114

>No they really don't. You only learn by doing and by being encouraged to do by people that have mastered the subject. He hasn't mastered any topics of mathematics, he didn't even get a PhD or contribute any research of worth.

PhD here, and what you say doesn't make sense as it really just is an argument of authority. You do not only learn by doing and by being encouraged by complete masters of the subject. You also learn by getting new intuitions and concepts through novel ways of explaining them. 3b1b actually has some of the best infographics regarding the subjects he's discussing. That helped me a lot with notions of divergence and rotational.

As for what you or whatever anon said earlier about learning secrets tricks such as Feynman's factorization, there are only so many "tricks" to be taught, the real trick is to get a good overview of what you're actually working on. Other people discussing a subject that you already master will help you see and interpret things in a novel way as you discuss the basics with the hindsight you have. To be perfectly honest, I know some experience electrical engineers that would really use watching a few ElectroBoom videos.

>>12037783

Absolutely. And might I add, it is also a good and quick way of reviewing basics for someone who already knows the subject. It will either give you more confidence in what you know or you might get a new perspective of said basics; or hell, it will remind of you something you completely forgot.

You tell me not to appeal to authority, I’m not appealing to authority I’m stating an obvious fact that you learn by mimicking the techniques of masters which is exactly how the office hours help session, PhD process and tutoring environment work by watching a more competent person do a difficult task in a skilled manner and then imitating them. Now you state you are credentialed and so have special knowledge of why you can ignore my critiques. What is the special knowledge?
>you learn by getting new intuitions
Firstly, you’d need to state what you mean by new intuitions. For me the idea of using topological and metric space ideas to understand continuity coming from just a calculus background was a “new intuition” that helped me understand ideas to do with optimization and integration more easily but that required reading lots of boring dreary preliminaries in multiple textbooks and doing ample exercises, I remember how much I hated doing that and how hard it was to gain insight this way. But, I doubt that I would have benefited from being spoonfed the “visual intuition” without being asked to think on my feet.
>that helped me
Ok that helped you I’m saying it doesn’t do anything substantive for most people. I would love to see the performance of most viewers solving intermediate level lin alg problems before and after his videos. Guarantee there is no significant improvement. However, a channel like Professor Leonard’s I’d bet good money that test scores go up after viewing his videos which is attested by the comments especially at the end of his Calc III series where you can see literally hundreds of people claiming just this.

That's a blind appeal to authority and a poor one at that. A PhD is a piece of paper saying that you spent several years beating your head against the wall to make a meager contribution to a specialized domain of knowledge in some field. It doesn't give you exclusive authority on the subject of mathematical visualization or even make you competent at it. Anything in the public domain can be reasonably expected to be understood by an enterprising member of the public, and research in general isn't owned by academia. Something tells me you're either in high-school or barely into your undergraduate education.

>You tell me not to appeal to authority, I’m not appealing to authority I’m stating an obvious fact that you learn by mimicking the techniques of masters which is exactly how the office hours help session, PhD process and tutoring environment work by watching a more competent person do a difficult task in a skilled manner and then imitating them. Now you state you are credentialed and so have special knowledge of why you can ignore my critiques. What is the special knowledge?
I'm not appealing to authority, on the contrary. i'm actually saying that I have a PhD and it's not relevant to the fact of having a PhD. Fucking everyone can be a PhD due to regulations making it so hard to fire you once you're qualified that even if you didn't do shit, the advisor would either have to write your thesis for you or you would simply get away with a shitty one.
Besides that, PhDs do not necessarily have more "knowledge" than a masters on such general notions. They may have specialized in certain domains, sure, but that doesn't necessarily mean that 1) they would be able to explain it in a pedagogical way (not everyone is Feynman) 2) that they actually grasp anything that is not directly related to their bibliographic research as phds. If that was the case, every tenured professor or lecturer with a PhD would be a good teacher, which we both know is not the case.
> but that required reading lots of boring dreary preliminaries in multiple textbooks and doing ample exercises
What you did was merely studing the subject. Which is what you eventually have to do if you want to be anything near competent. But for all the textbooks you've been studying, all the problems you've been solving, there will always be that one detail you may have missed. That's why we have paper reviews in scientific journals, that's why we have plenary talks in conferences. They're basic, sure, but they allow you to do a quick tour d'horizon that will then help you redirect your research.

> I would love to see the performance of most viewers solving intermediate level lin alg problems before and after his videos. Guarantee there is no significant improvement.
The fact that you gave me Prof. Leonard, a guy that is really just giving you math lectures (albeit in a very pedagogical way, i'll give you that), proves to me that you're really all about those grades. Academic scores do not necessarily correlate with a deep understanding of the subject, and what 3b1b does has nothing to do with improving your academic scores. 3b1b provides, through his talks and his infographics, a good way to understand things in a way that is different from what your average lecturer probably showed you. That's the whole point.

>Firstly, you’d need to state what you mean by new intuitions.
Take a complex problem. What are the ways you'd think of solving it ? What are the steps that you might believe are problematic ? Why is that problem complex ? What are the mental, mathematical, or physics tools you will use to solve those ? How do you visualize the problem ? All of the work you do before you take your pen and paper and start writing. That's what an intution is. A concrete example i'm familiar with is "How will an ultra wide band antenna working at 5GHz might look ?". Sure, you'll just pick up the classic textbooks in the field such as Balanis or Kraus, or even look through some scientific articles. Until one day a fucker that eerily looks like 3b1b tells you "what if you've been looking at this problem the wrong way" and you end up figuring out your own design for a wider band antenna.

Again 3b1b is a content aggregator. you're not fucking supposed to just take what he says and stop at that. For many viewers, it'll be the case, which isn't really bad ("the more you know"). For others, which i guarantee you is not only my case, you're listening to someone else's educated opinion on a certain field with good visual effects, 20 minutes on the train home.

>>12040303
>Academic scores do not necessarily correlate with a deep understanding of the subject
Academic scores demonstrate a competency with the subject, and in higher level graduate classes, one finds it difficult to achieve high academic scores (especially in mathematics) without a moderate-to-deep understanding of what is being taught. Of course this could depend on the instructor, but typically in a rigorous, theoretical course one cannot get by on just "intuition", and a high academic score demonstrates an understanding beyond intuition and "concept", which is what 3b1b shows in his videos.

This is a good line and I have nothing to disagree with here. In many ways, 3b1b treats many subjects as Eugenia Cheng treats category theory, and I think there is a risk there of giving a wrong impression (which it already does in my town).

3Blue is both a pioneer in math education and fairly over rated. For someone with such a passion for helping people understand maths for maths sake he sticks pretty hardcore to college curriculums designed to make productive worker bees; he even hand waves almost all the same important concepts for actually understanding the math completely, deeply and in order.

Most people view popsci as a way for normies to get in on the ‘cool’ and ‘smart’ aspects of science. This is the inverse, it normie sci: giving autistic people license to virtue signal their math fact memorization skills to normies.

No. Just no. You can actually cram your way into a masters. In fucking Asia, you can even cram your way into a PhD by making incremental fucking papers. And even then, most if not all 3b1b topics are undergrad level, so your point doesn't really stand, besides the fact that not everyone that watches his videos are only studying maths tangentially and are okay with not delving too deep while still getting a good understanding of what's going on. You don't need to have a deep understanding of electrical engineering to be an electrician, but it's always nice to understand stuff works physically as it could possibly help you troubleshoot in a more efficient way. But would you need to (and would you want to) cram through masters degree level textbooks to get there ? Fuck no, a few videos and you'll probably be good.

Your point, from what I get, is that if you want to learn something, you just gotta whip up your textbook, pen and paper and you'll be good. And I agree with you, that's a good fucking start if you ever want to grasp something at a level beyond natgeo documentaries. But you can't do that for every fucking field you're interested in, grasping at straws until you do enough exercises to know what the fuck is going on.


And it's honestly just not bad content.

I brought of Leonard because in spite of the incredible simplicity of the topics he teaches people he does so effectively and with the intention of breaking down the entire process step by step for the sake of giving his students and viewers the capacity to solve problems. He wants you to understand how to do things rather than appealing to the why and he uses the most stripped down version of the analytical intuition involved at the higher level for motivating this, see for instance his discussion of the Frenet-Serret equations or the fundamental theorem of calculus, his lectures on Taylor series all of which are really good at doing what they're intended to, making people capable of handling these ideas in applied/computational settings. For the rigorous analog you have Michael Penn who provides again step-by-step detailed demonstrations of fundamental results in undergraduate mathematics including the actual proofs you'd need to supply in a homework assignment or on an exam for earning a grade. This is important because much of the intuition is bound up in the process of developing the proof and you would not truly appreciate much of the "intuition" as 3B1B would like you to think of it without knowing how this works and why it must work and there is no reason it could not work.
>Sure, you'll just pick up the classic textbooks in the field such as Balanis or Kraus, or even look through some scientific articles. Until one day a fucker that eerily looks like 3b1b tells you "what if you've been looking at this problem the wrong way" and you end up figuring out your own design for a wider band antenna.
For me intuition is the ability to immediately see why something must necessarily follow from basic ideas, and why we should use the structure of the theory as given to deduce further results or why it is we can easily solve a problem by using a set of models or assumptions that are reductive and easy to work with.

Why don't other autistic kids obsess over Maths and/or Physics? I'm not saying that there are not autistic kids that are interested in these things, but the ones that I've met in person are interested in video games or dumbfuck fandoms. I'm also not claiming I'm some super genius. I only have an IQ of 114. I suspect the reason why I'm not obsessed with these things is that my parents never let me play video games as a kid, so I just watched YouTube videos about Earth-like planets all day like a fucking sperg.

>>12030526
every popsci communicator faces the same paradox: most of their audience doesn't give a shit about their content and is just there to "get mindblown".

3B1B is one of the few who consistently tries very hard to break through this mentality. I don't think he succeeds but you can't fault the guy for trying.

I think there are some higher level youtubers, but anything requiring effort will not be watched - so by that logic there can't be anything "higher value" that's science/math and known enough to be discussed here.

Math in school is taught in a terrible way that doesn't make sense to a lot of people, so they ignore learning it any further.
By teaching math in a different way, one which shows more practical uses, those people can see the actual application of mathematics and work backwards into learning the actual math behind it.

Not everyone is a bookworm that wants to spend hours reading mathematical textbooks purely to mentally masturbate.

I want to add in relation to this that when Ptolemy (the king I don't remember his number though) asked Euclid if there was a faster way to learn math without having to go through the basics, he replied that there is no royal road to Geometry which means that you literaly can't learn math if you don't start from the begining and slowly learn to the top, building upon your accumulated knowledge. A lot of popsci fags probably don't even know what a derivaitve is, yet the nigger called 3b1b makes videos about partial differential equations and Fourier Series. To learn that shit you need to know about Sturm-Liouville and boundary value problems, for which you need to know ODEs and they require at least single variable calculus (maybe even multi variable and linear algebra for some parts). You can't just skip straight to Fourier and PDEs. That's what Euclid was telling Ptolemy and that is why 3b1bs viewers don't learn math at all. I think a lot of popsci is just trying to make that royal road to its subject for the layman who doesn't know shit and at least for math this is just impossible.

It's completely useless to them and disembowels the concept for the sake of accessibility.

Engis use them and don't know what they are but they have to take classes to learn to use them like the monkeys that they are. Normies watching infotainment videos aren't even reaching the level of "proficiency" of a retarded engineer.

Pop-science is only a problem if it actually misleads in the subject. Having looked through his videos, I would say he doesn't do this, although often over emphasizes geometric intuition.

Many physics channels are guilty of this, I'd say. Science Asylum is one of the few that I will say doesn't mislead too much.

>>12045002
A layman doesn't have the required knowledge to learn it. People itt are claiming that people can learn from his popsci videos.
>>12045674
Yes he does, he also has one on linear algebra. I haven't watched either but these are just two of the preliminaries for PDEs. That really limits him in what he can present in PDEs, so he only presents the heat equation (he also presents Fourier series in the same video) and I doubt that he even mentions the non homogenus problem cause that requires the other things I wrote. Also I doubt his calculus and lin algebra series teach them to a sufficient degree cause his intro to differential equation video pretty much sums up to:
>lel they are *FREACKIN* hard to solve
>you can solve this one by integrating twice
>here is le ebic phase space
>present less than half of the basic idea of stability
>OMG dif eq can describe love!!!

Are you retarded or did you just stop reading at the Greeks? If you think it's possible to teach math starting from the most advanced things like Fourier or PDEs and work your way down to calculus and elementary arithmetic, you are fucking retarded.

a layman doesn't want to "learn it", he wants to see some basic ideas out of curiosity. like if your non-math friend asks you about your phd and is willing to listen for 10-20 minutes. so what exactly is so bad about making such videos?

>>12046241
I can tell you are a retarded engi because you didn’t read the post, you take a class on mathematical methods in physics or “introduction to fourier transforms” or something along those lines in engineering and they teach you how to mindlessly apply the fourier transform. However, that is not at all what he advertises his videos to be conveying which “intuition” except you would need functional and harmonic analysis to understand the fourier transform intuitively.

>>12046245
I guess you missed the
>People itt are claiming that people can learn from his popsci videos.

His videos do try to teach the topics but of course they fail miserably not only to teach the layman but also to teach anyone cause he simply tries to skip stuff and doesn't even present other important things.

>>12046247
>you are an engi
physics, not that it matters.
>you would need functional and harmonic analysis to understand the fourier transform intuitively
I'm sticking with my opinion here. You don't need anything to intuitively understand FTs.
They take a signal and give you its spectrum. Knowing your functional analysis helps (a lot) in what you can do with them, but you don't need it to see that you can get contributions of frequencies, for example.

>>12046267
you can learn a lot from his videos. for example if you're a STEM student failing your linear algebra course because you can't see the ideas, only mindless manipulations with matrices. or did you mean "learn" in the sense "substitute a textbook or proper course"? yeah, I think nobody claims that.

>>12046299
If you can’t do anything with the knowledge it isn’t real.
>>12046270
If you want mathematical intuition you need functional and harmonic analysis. He neither teaches you graduate level analysis nor does he teach you how to use FT because its fucking infotainment and not real instruction. You people keep confusing interesting videos with useful and worthwhile education. Michael Penn educates people, khan academy trains people, 3B1B does neither.

>>12046314
>mathematical intuition
>shifting the goalposts

you don't need to know how do do a FT by hand to use it. You'd use an implemented FFT anyway.

>>12046314
>>12046322
to add to that, his videos are not supposed to replace studying. They are a great addition while diving into a topic. I don't know why you're acting like it's supposed to be a lecture.

>>12046345
because you only learn from doing and by demonstration from people that do the thing in front of you. the advanced special intuition grad students and professors meme about comes from doing. you cannot convey it cheaply and freely to the public by visualizing a stripped down and decontextualized version of the concept. no amount of analogies will allow you to understand QM and no amount of CAS visualizations of linear transformations will explain the spectral theorem adequately. It’s obnoxious that people conflate his videos with intuition, they are even self styled as the “essence of x” which is disgustingly pretentious considering the essence of calculus and linear algebra are both analytical and algebraic respectively ie non-visual and bound of in abstract (non-visual) reasoning.

I don’t give a fuck if retards want to vegetate and absorb fake insight on YT. It’s only the claim that you learn from that shit in a way that’s either not available in texts and lectures, absolutely false go to a good school or read a good textbook, or that’s some special advanced intuition, false and bullshit intuition is verified by extraordinary reasoning and no one comes away from those videos capable of intuiting higher level structures, this enrages me and should be challenged. The quality of math and science education in America has fallen precipitously due in large part to educating fuckwits that don’t belong in university or even highschool and appealing to the false preferences of the public. People say “i’m a visual learner” but would struggle with the most basic geometric exercises taught to 8th years in an early 20th century eastern euro technical school. They say they like applications but god forbid you make anyone use calculus to do physics. Faggots like 3B1B pretending to geometrical wisdoms flaunted in front of 90 visual-spatial iq dipshits that can’t unfold a box in their heads.

>>12046345
>>12046322
It’s ironic too that he pretends to teach calculus in this intuitive visual manner when Zorich which is a brutal eastern euro style combined calc and analysis text actually does just this but there are hardly any pictures at all in the entire two volume book set and yet you gain incredible geometric insight into analytical concepts from doing very fucking hard physics and analysis problems and proofs. Keep in mind a lot of these viewers literally cannot do a fucking trigonometric integral without fucking up so teaching them super secret transformations of the plane to represent change of basis does nothing for them practically speaking.

So, the alternative is keep all such math hidden away in the attic. What is even to inspire further study of such concepts then? The only possible such damage a video can do is if it misleads. I don't see this in his videos.

>>12050361
Conveying the “intuitive and visual” aspects of abstract formal mathematical concepts to the public in a manner they have been “denied” by the deficient and outdated educational system and providing entertainment and inspiration to any and all that would like to experience the “deeper” aspects of mathematics. It accomplishes well it’s second aim, the first is a hilarious pretension to special insight that the guy doesn’t have and that can’t be transmitted via python animations.

>>12050369
No, you can easily access countless lecture series, wikipedia articles, lecture notes, OCW pages, and free online textbooks explaining mathematics all the way up to the research level online. This is how you learn math. Infotainment only misrepresents and degrades specialized technical knowledge.

>>12050372
I am well aware of that but only after math was introduced as something that could actually be interesting by such videos. At worst, you get someone that develops an ego in the subject. This type of person likely wouldn't have entered math anyway. So, where is the real downside?

Given your list of ways to find out about a math concept, you essentially cast it away in obscurity before you've dared to enter anything related to higher math. Before then, have fun with epsilonics.

Also, I think it's clear 3b1b doesn't 'teach' math and he emphasized that in 'the essence of' series, he adds a certain perspective to it. Whether you think it's the right of wrong way (sometimes I think it's right, sometimes I think it's too geometry heavy) is a different question.

I will say that it is utterly pointless to try to explain something like homology to someone without the prereq, but calculus? Linear algebra? DE and FT? These last two you don't have to enter functional analysis to study-they got you immediately in physics books in QM. Sure, functional analysis will aid its understanding later but physics students are there to do physics.

>>12050409
I’m not sure I follow your logic, you’re denigrating “epsilonics” as if the process in analysis is somehow regressive or insufficient for understanding which is something I’ve never felt was true. You say that i’m relegating higher math to obscurity but from the view count on MIT OCW series and prominence of sites like stackexchange it seems that many people in the general public know perfectly well how to learn on their own. Is it the responsibility of academics to popularize mathematics and science in your view? We have countless accessible pathways for exposing highschool students and post-graduate laymen, Nature even runs explainer articles on a weekly basis for all kinds of technical topics. So, perhaps there is a necessity for hs educators to spend more time providing ample extra references to students as is common in undergraduate math settings.

I send that 3B1B has really two well defined goals, the second that I gave is something he has succeeded very well in. I’m sure that far more people are now aware of and intrigued by fourier series and the heat equation because of his videos. That was not my critique of his channel and would be an absurd point to trifle over given how many inferior explainer videos exist on youtube.

Linear Algebra and Differential equations are taught in a barbaric unintuitive unrigorous factory style in most major universities to scores of untalented drones that fill the ranks of engineering and software firms in America. Making some concessions for the real thing, Arnold and Axler style renditions of these undergraduate topics is an under exploited avenue for education. Michael Penn, a content creator I’ve brought up twice in this thread, does exactly this presenting roughly Pugh/Abbott level Real Analysis with proofs, examples and background motivation targeted at a general math adjacent and undergrad math audience.
