The Hope Diamond (with 3blue1brown) - Numberphile Podcast

first of all let's do with the transatlantic thing do I call you grant Sanderson grant Sanderson grant Sanderson grant Sanderson so all of my British relatives call me grant grant so I would have a certain affection if that's the way that you wanted to say things I would say grant grant Sanderson so you go to the aunt in the Sanders and not the art of massage getting into my Virginia route I guess okay but yeah all right I'll try I'll try for grant but I may sleep into grant occasionally I've never been asked about how to pronounce my name I've always thought of it as a a standard non miss pronounceable thing yeah well I can as you see I can mispronounce both of them say I wouldn't consider either a mispronunciation okay hi I'm Brady Haran and this is the numberphile podcast you've probably figured out today's guest is a guy called grant Sanderson grant Sanderson now grants the man the brains and the voice behind three blue one brown and if you know what numberphile is you probably know what three blue one brown is cause it's an incredibly successful brilliant YouTube channel all about mathematics today I'm gonna be talking to grant about their and about other bits and pieces from his life and mathematics but before we get started the thing I really wanted to establish is this why call the channel three blue one Brown I'll start by saying there's two ways of explaining it so the first is the very direct it's a weird name it's named after the logo with which is a loose depiction of my eye color which is 3/4 blue one color brown on the right side although the closer I look at it sometimes I realize it's not as clean a fraction as that but I give you a look back on all right yeah I'd say maybe it's about like 2/5 either way you know we can acknowledge that's a weird name putting it as the logo I mean there's some meaning to that because in the same way you'd put your name on your work like having a genetic signature and the whole channel is about seeing math seeing it in different ways and to some extent maybe like I want to show people the way I see it right so some sort of individuality there maybe makes sense so this is your eye we haven't expired I interrupted and didn't let you explain probably you've got this thing what's the code in your eye that makes the color I think the official name is secretory all sectoral heterochromia right basically it's just two colors so there's like a segment that's brown and then the rest of the I forgot to pigment itself so it's a different color like you see it in dogs a lot Huskies that have all different eye colors but for someone who's never seen grant by the way in person it's not particularly noticeable oh you'd have to be right up close and looking for it like you do it like just like a blue eyed guy but it's just like a slight little little tinge in one eye it's quite you know I used to notice like if someone would notice it in my mind that would up them in the like ladder rung of friendship as oh wow we've made enough eye contact that we're now at this point where you've noticed this weird and otherwise not super noticeable feature about me which is maybe why I had that as a weird part of my identity so much so that I'd be willing to name a YouTube channel after it right you also have to like I wasn't necessarily thinking of this is gonna be a channel that's gonna grow and I want to have it out there I'm just putting a name for a thing that I wanted on a particular project that yeah I I didn't necessarily think strategically oh if I want this to be ranked high in search algorithms for math how is it gonna go it it was kind of just a silly little thing to put there so you created this really cool little like stylized logo of the eye and that's kind of that's on everything you make that's like your that's your brand as you said you didn't know how successful this was all going to become if you could go back in time would you still go with that or would you give it a more math search optimized name or do you think the name helped the quirkiness of the name has hoped in your success well also this gets to the second answer and why do I name it I have a strong belief that names should be weird should be something notably different you know if you're if you're running like a pie shop in your town it should have the name pie in it so that people know what they're looking for but if it's an entity on the internet you know I do think there's an element of building your own brand into it yeah you look at what whatever your most popular website is a Google or a Facebook or Twitter there are objectively weird names the first time you ever heard one of those names it's just weird so I kind of wanted to lean into it that way the only name I can think of for a company that I actually think is actively bad is a place I used to work for my food I'm wearing their shirt right now it's name is affirm AFF i RM which is a fine name they do things associated with payment and they want to affirm that it was a valid payment the problem is then you're talking to someone they say where do you work you say oh I work at a firm ya know it's a stupid name okay there's also in Silicon Valley someone named a company as in they accompany you through your life but boy is that not so for a company unless there's name collision I think not only is it okay to be weird there's an advantage to that so I don't know if I would change it if I went back in time in the same way that Kurt's kiss tots whatever it is yeah the fact that that's the first example that comes to my mind for weird names is good for their branding so it didn't change it they kind of tried to change the name a bit didn't they they kind of start if they stopped I tried to push it to be more cold in a nutshell which is what curves cuz that stands for I think and like I think there was like a backlash in the end they were like no you're right let's just stick with that speaks to what the internet likes once they latch on to a meanness yeah yeah so one last thing about the name then because you saying before that you're you know you're quite an introverted person you're not like really super outgoing do you find though having that name and people knowing that's why it's called results in people like staring at your face yeah it's more than you're entirely comfortable with when they make you for the first time oh when I meant for the first time I'd straight away I wanted to say it like you know yeah a little bit but it's not I'm not you know George Clooney walking down the street someone's saying hey it's because I don't really have a recognizable face either it's not like a main part of the channel that someone would note so every now and then it happens that someone might recognize me actually you know what happens often is they'll recognize me by the work I'm doing on my laptop if I meant like a cafe like pie creatures and on it and such yeah I don't so much mean like strangers coming up to you and like yeah sure like at a conference yeah yeah yeah it happens a little bit but all right honestly usually how it happens like all can I see your eye and then there's it's like looking at the Hope Diamond you're pretty disappointed that it's not actually that noticeable a feature you realize you just compared your eye to the Hope Diamond that's not in how underwhelming it is okay right I think the level of hype of the Hope Diamond compared to what it looks like yeah has the same ratio as I don't know if you call it hype with the fact I had a channel after my I to what it actually looks like then that ratio is the same even though the absolute magnitudes are quite different okay if I had met you when you were like schoolboy or very young would I would it have been predictable that you were gonna end up being like a math filmmaker type person like was it was the writing on the wall was that were you like the math kid uh math yes filmmaking no I did not know and still really don't know how to make videos but I've always been into math and I think some of my earliest memories to point to this fact I had a dad who was very interested in making me be curious about the world one game that he would play he'd stack sugar cubes and interesting geometric patterns you know maybe it would be like a three by three by three cube of sugar cubes and say how many are there and he so know if you're very young you don't really know about multiplication and maybe you try to count but there's one you can't see so there's some notion of pattern recognition there and if I would get the answer right he'd feed me a sugar cube so you know Pavlovian affection okay let me put them in more and more interesting patterns yeah also man he put he must have put a lot of time into this project he made this thing where he could sort of stack marbles in interesting pyramids but one was like a hexagonal pyramid so he would drill these very precise holes and everything's my sphere packing oh yeah it was like a sphere packing thing I guess and again it was a notion of just counting things in certain patterns and at that point more so than the lesson itself I think looking at your dad be so willing to spend a lot of time in a project about a thing makes you interested in that thing right and he himself you know he's not a mathematician I don't think he actually went much beyond calculus in school what did DJ what was his work he's a pilot actually yeah so he he's pretty comfortable with numbers he's comfortable with numbers he loves reading about science he stuff right like he follows your channels like that kind of thing but this wasn't like the mathematician trying to make his son into what he is it was actually a very adamant that my brother and I not follow in his footsteps into like Navy and commercial pilot guess he thought that was becoming a more and more difficult career path yeah yeah but as far as like instilling a love for curiosity and the a specific character of that curiosity's towards patterns and numbers and that started very young so you were always on this math path you were like the math kid getting the good marks and but it was never too poor that wasn't like you had other other ambitions or passions that were gonna that could have taken you elsewhere yeah I think if you interviewed someone in my high school and you asked about like that Grant Sanderson kid you would hear the word math and their first sentence somewhere I would no surprise McDormand I oh yeah he has eyes like the Hope Diamond yes at least what all the ladies would say yeah at that time all right so so the path was inevitable and then what happened when you finish school where did you like where'd you go to college and stuff so I went to college at Stanford and it's at that point I started getting pretty heavily seduced in the direction of computer science and you know there's a lot of parallels between computer science and math not just insofar as the latter applies to the former but the structure of writing a good program is similar to the structure of writing a proof and things like that and I loved it right I think one of the first things that I made that wasn't assigned to me was a a four dimensional graph err so I just wanted to see what four dimensional shapes look like hey I can make the computer show me what their shadows look like and that just felt awesome and it's very empowering and it's very different from math in that you have an entity telling you when you're wrong the compiler and you have to own up to that fact it's not like an English essay where you can argue about whether your point was interpreted appropriately no you're wrong you have to live up to that yeah and that makes you improve yourself and it's also very precise and technical so obviously that aligns with math so were you majoring in math and like dabbling with computers on the side or were you doing computer courses at Stanford ah computer courses yeah so his major I was majoring math I always knew I would want to major in math and then I'll always take a computer science class as well because you know math is actually a fairly like major as far as units are concerned and the people I started to hang out with were much more in the computer science side of things and you know you're much more influenced by the people you spend your time with than you are by pre-established passions in some way yeah so like a the first summer after my freshman year I sort of landed an internship that I didn't have the merit for but was happy to be given the opportunity at a certain place in Silicon Valley that started off as a less than fully technical position but you know once you're in an organization and you sort of sniff around and find the right people and you ask what they're working on and you say hey can I help with that in some way yeah got a little bit of more concrete programming experience and again you know that just sort of bumps up the addiction what happened then were you being seduced away or not like what what what stopped you saying is throwing in mathematics that point saying like I'm gonna sign on for computer science I'm loving this all my friends are into it and I think it's the difference between programming and software engineering where as soon as you have to make a bunch of different components work together in I don't want to say unsexy ways cuz that makes me sound like a prima donna who only want to work some things that are super interesting but there are other aspects that I just felt weren't in my wheelhouse as much and are kind of I don't know it's a if you're trying to get some old system to talk to another old system and that's what it takes for the company to actually have a valuable product that's less inspiring than creating your own four-dimensional Grapher and things of that sort right like what programming means can be quite different and I think it becomes progressively less sexy the farther you trudge into that career is the view that I got so was that a feeling like you didn't want to end up being just like a small cog working on technical problems you want to be making things that were like you wanted to have more control and do more cool things if I'm really honest with myself I think it might have been kind of indulgent in that I felt like hey no I love math and I had this notion of that is a possible career path is to do the PhD be a mathematician that kind of thing yeah so maybe I should try some career path that lets me fulfill that love of math or not necessarily the traditional one like try something a bit weirder so like by the time I was finishing college I'll probably jump back and forth here a little bit yeah but I had made I think one or two videos that were on what is now the channel yeah and those had started as like a mix of math and coding project because I wanted to have my own tool for visualizing things and one thing led to another where that made it possible to have this position at Khan Academy creating math videos so I started to think okay maybe there's a possibility for a less traditional path into some career where you are engaging with the math and also programming for that matter in the ways that are more fun and let me see if I can try to forge something out here it's weird it's a little less known I don't have a concrete plan about what three years from now looks like but I have a sense that like the positioning is probably not too bad if I have like you know Khan Academy is a meaningful name in the world of like education so yeah not a bad feather to have in the cap so those first couple of videos you put on YouTube that you know ended up helping you get noticed by Khan Academy and pushing you to where you are now what made you put those on YouTube though like you don't know you don't seem like a show-off who would want to show everyone whose work and stuff like that like what made you want to make it public and put it out there the most honest answer is probably like people like you the fact that this was somewhat established I didn't so I didn't really know the notion of what it meant to like be a youtuber to give an example when I did put that first video out you know you get some email from YouTube this is like ah you have 27 subscribers and I remember thinking what's a subscriber and I so I had a notion that like minutephysics is a thing number there are humans behind the in some sense this is a part of their career so that wasn't completely foreign but anything more specific than that wasn't there so I think if I had if it had been you know five years earlier that probably wouldn't have been my instinct I'm not really a first adopter in that way that some other people they see this new thing they want to share what they're doing so they put it out there so you were consuming a bit of YouTube content so it was like it was in your it was it was in your on your radar to put something on YouTube just because you'd seen other stuff when you choose yeah and I mean I think this is like there's a whole category of importance for the kind of work that like you do or Henry Dora Destin did there's like way early on that is extremely hard to quantify which is the number of people inspired to do similar things I definitely know at least one do you know the channel welsh labs it's like another he does some really good math stuff um he has the series on imaginary numbers that's great for example and talking to him he said my channel probably wouldn't exist if minutephysics didn't exist because that provided a bit of the inspiration and also you know pattern matching isn't great but it's a way to get started and it's um as soon as you get started then you mold something into your own it provided a pattern to match from for a style that felt more approachable than like being on camera which a lot of people aren't comfortable with so these videos you make like you know a good and therefore you end up getting it worked I learnt great okay the very first video may still feel a little ashamed of but it needs to get the ball rolling [Music] eat the pie I equals negative one is one of the most famous equations in math you've resulted in you getting work at Khan Academy that's true yeah what was more responsible for that was the conversations that started to be had where I you know went down there for lunch and I really connected with the people working on their math side of things so I had these Fridays and I think at that point there was then enough goodwill that they could see the good in them and maybe look past to the amateur nosov how they were put together also because Khan Academy isn't necessarily about like fancy videos that are super well polished maybe that actually played into it whereas if I had been a trained filmmaker that might have countered to it really worked against me [Music] so just going back a little bit then at what point do you make a decision or is it not a decision is it something that has happened accidentally between being an actual practicing mathematician and trying to solve problems and being an educator or an outreach type person what like what made you choose one fork well I think maybe around senior year of college I thought it could be a good idea to take a gap year at the very least between undergrad and PhD which is common in some disciplines but not too common in math and not necessarily smiled upon by graduate departments two things probably informed that one having had internships that were totally outside of academia in that time realized it is very beneficial to get your head out of academia for self-improvement for just better knowledge about how the world works for just meeting a different kind of people all of that so you know I think it was much more likely if I was going to be a successful mathematician it would be because I had a slightly different past than it would be because I was the greatest in math because I wasn't and the other thing was a little bit of doubt about the specific field that I wanted to go into and it's I think very important you know if anyone's going into some PhD do it based on who you're working with first right like what person will be advising you if you're in you know more of a science like what lab group you're going to be in rather than what is easiest or what has like the best brand name associated with it and because I didn't have that clarity I felt uncomfortable setting in stone anything that would be effectively like a a five-year lockdown so a little bit more time to explore different things felt like it was needed but during I think that first year it was definitely in my mind this is a gap year and this is I will at some point like go back and maybe go down that path but I do want to keep my mind open to if there's a different path that exists and another another factor coming in here also is a little bit of skepticism about the stability of the university system and especially the American University system through the next few decades or I don't know if I want to throw all of my eggs in a basket that has like trillions of dollars of debt as like a direct consequence of it in the background it's hard to know how things pan out for like what happens to what currently exists as student debt that some bank accounts as its assets when suddenly they realize that it won't be repaid ever but I can't help but feel that the job prospects for working mathematicians aren't going to be super great as a consequence okay that's just my own cynicism all right so what you thought you thought it was gonna be more stability on YouTube honestly yeah not YouTube per se but the internet like I'm much more bullish on the notion of establishing a platform for yourself rather than being in a old system maybe that's a little bit naive I think that's definitely informed by having had ones formative years growing in like a Silicon Valley environment rather than other ones yeah but I do think that I don't think YouTube itself will be like the stable entity you know twenty years from now but the things that it can lead to yeah if it works so take me take me through Khan Academy two three three blue one Brown like what what happened how long were you there and what we're doing and then how did you evolve at the very beginning so they had this thing they called the Talent Search which it was always unclear to me exactly what that was is this a recruiting thing I would ask they would say kind of but it was a thing where they invited people to submit educational videos and they would select some winners and like bring them out to Khan Academy and to YouTube to like to her around and it was kind of a recruitment thing because they were growing their content and beyond just sal putting out videos yeah nevertheless it took a little bit of pushing and weaseling to turn that into any kind of job offer and you know the way that happened is I first offered to just do like two weeks of sample work like I will write some things see if you like it yeah and kind of let it grow out from there right it's always a foot in your door situation and so I was eventually hired again it wasn't like a long-term thing it was a one-year fellowship and there were were so there was like a biology fellow there was an electrical engineering fellow there was people that they would bring in usually having just gotten their PhD like the electrical engineering fellow had like finished a career at HP so a very different and strange group of people what age were you at like you just graduated undergrad I was like under qualified in some sense but I like to think I know how to explain things and to like empathize with a student yeah and in some ways I think you're better at empathizing with a student if you haven't been spending your last you know five 10 years in research yeah because it's a very different dynamic yeah so I start making multi variable calculus content for them which is not just videos but also like articles and exercises and such and then like any job there's a bunch of just odd job little things here in there outside of that and when I so when I started like three balloon ground was not a big thing by any means is like a thousand subscribers it was just a side project but the channel already exists it exists yeah existed it wasn't big so then we progressed further through the year and I every now and then put out something on the channel and at some point it fell some of the videos fell into the good graces of the recommendation algorithm not unlike a viral scale of things but you know at that point if you see that has like 20,000 more views in the last month like that can be a big thing to you yeah I did like a project with Steven Strogatz which was really cool for me that he was even open to that [Music] for this video I'm doing something a little different I got the chance to sit down with Steven Strogatz and record a conversation for those who don't know he's like a popular math author he submits our like columns to the New York Times and it's been on radio lab a number of times and I think he's very open-minded to new math outreach things happening yeah so it's this complicated word first of all brick ista crone that comes from - gee I have to check are those Latin or Greek words I think I'm pretty sure they're Greek okay and so the channel grew a bit long story short like questions then started to arise what is the relationship between three blue and brown and Khan Academy from the question should have been asked and addressed long earlier at the beginning but partly it just wasn't big enough of a big thing partly they didn't have a precedent of other content creators and as those questions started to arise we did a couple things were like maybe we marry the two yeah and I realize that's actually a bad idea unless it's gonna be a full like it becomes part of Khan Academy and rebranded to Khan Academy or they're totally separate things and like long story short it sort of made sense to like part ways yeah in one way or another and either that would mean okay I'll get a job somewhere else or like go back to trying the PhD thing and the channel will still be a thing on the side yeah or you know let's just see what it looks like to spend will time effort on so you go Olli and on it for a while and see if you can make it big which you know I wouldn't have opted in for without any like external pressure knowledge at that stage it was it wasn't tiny I think it was maybe something in the sixty to eighty thousand subscriber range right yeah so not negligible not something I would recommend someone say oh I'm gonna try this as a full-time job not big enough to like make a full living out of exactly living in the Bay Area exactly right but I'm young and I'm not tied to a family or anything like that so if ever there's a time yeah this is the time and that that proved to be valid and again I benefit from the fact that YouTube and the industry surrounding YouTube had existed for a while so patreon was a sort of mature or a maturing thing at that point yeah notion of you know like sponsorships or such were there and I I sort of was of this like let me try all of the things and see like what works out and then over time have been a little bit more I don't know thoughtful about exactly how I want to approach stuff so after you'd left Khan Academy and then you started going like all in on three blue one brown and then like you know it it exploded really quickly like a it grew like really it became massive very fast do you think that was because because you'd gone all-in you were putting out more videos or you were putting more time into the video so they were better or there was it was a coincidence like what it seemed like as soon as you said I'm going all-in on this it went big straightaway I think more time into them definitely helps you know like I said I still feel like there's a lot of aspects of just filmmaking I don't really know but certainly I've been like learning more over time and I like to think like the videos I've been getting better and hopefully two years from now I'll look back at the ones today and cringe for some aspect of them right so I think that's it I mean there were a couple punctuated moments of clear helping hey Vsauce Michael here at some point michael stevens vsauce i've mentioned it this channel is fantastic by the way I'm a huge fan the visuals and explanations are top-notch I didn't know about that ahead of time or anything I just noticed one day suddenly there's a huge growth and like you can see in comments like came here from Vsauce yeah and I had never met him so I kind of reach out to say thank you in some way and it turned out the way he came across the channel was one video I made called like who cares about topology and I had felt proud of that video actually when I made it I that was the first one that I made actually after leaving Khan Academy and really like pouring myself into it so maybe in that way that was kind of a nice little payoff there yeah one actually huge helpful thing from and I mean from the very beginning Henry was like very comfortable just providing advice and mentorship on various things hey Henry thanks for watching this is Henry from minutephysics yeah Henry racial minutephysics yes just the nicest guy in the world yeah I was inspired by my friend Grant Sanderson who makes videos over at three blue one brown you should go check them out they're great longer form math videos you learn a lot in them I know as he and I got to actually know each other more we realized we connected in a number of different domains like how we each play the mandolin after having like grown up playing the violin and he sure liked the outdoors and running like there's there's number of ways we like personally clicked a little bit more yeah and obviously we're both nerds about physics and math yeah so him both providing advice and also like he was very kind in terms of mentoring a channel on his which you know he didn't have to by any means yeah we did a collaborative project later on things like that just sort of helped out and I think also you know I think it's important to read the negative comments and when they're written in good faith like take them to heart for improvement you know there's a lot of things I was doing earlier on that at the moment I felt was the right way to do it that was just wrong what's an example of that was an example of a comment that came from a total stranger that changed the way you were making your videos okay so the very first video I put out I I was talking pretty quickly in it and I think at that point I was pattern matching more than I should have off of various you know like Internet me me YouTube things where it's just this fire hose of information you're talking faster than someone can understand but that's exactly what's pleasing about it yeah and that has a role that obviously can get very popular on the internet in some domains but I think I don't think I recognize that in the context of math you know it takes a lot of brain energy to understand what's going on yeah and it goes from you know in a context like history it's kind of pleasing to have facts thrown at you in a certain mindset yeah in contexts like math all that does is like bring to mind days of confusion in school that were painful that you don't want what you actually want is to understand something and to understand it it has to be pasted better so I have to say that's like one of my favorite things about watching your videos is and luck because I my videos I always get told a to long by like you know family and friends and I say no no I want it to be at the pace that I understood it when I was filming it like to go at the speed of thought I think you do it even better in your videos I was watching your for ei1 this morning actually and like sometimes you just stop for three or four seconds and like something can just soak into my brain it's like you just say it's a a point and you're like you just like going mm-hmm did you hear that did you understand that and I'm like I'm like grateful for those pauses so I do I think your pacing is very good and you think you're thorough your viewers inform for that you're telling you slow the hell down one exactly right in language either that for force fuller more yeah you know some aspects of like which of the visuals were more confusing you know sometimes I would be hesitant to improve things because like ah that's gonna take a lot of work to make it look in this different way yeah it's hard to think of more specific examples but obviously there's you know especially as things grow more then you start to get negative comments that aren't even written in good faith yeah if you're small enough luckily the only people who are crazy enough to stumble across your channel are into niche things and like willing to give you some sense of goodwill yeah so I think a pretty good rule of thumb if it's something written with proper grammar listen to it if it's something written without proper and you know maybe disregard it and make sure you have a reason in your mind while you're disregarding it yeah you know I'm not saying listen to what people tell you because sometimes they are wrong for like whatever reasons yeah but III do think the whole movement about like don't read the comments or don't let that get to you or you know haters are just gonna hate that that can be taken a little too far I'm super biased by having like a math channel on the internet which is much less inflammatory than some other people's content you know I acknowledge that but you know I think I think there's a strong role for criticism you mean what percentage of comments written on your videos would you guess you read oh these days and not as many as if it's the day of yeah if it's the day of a publication I try to read all of them yeah as far as those they're like ambiently coming in since then you know when you're like bored sometimes you're scrolling through things like one of the things they might scroll through his recent comments yeah I almost never read replies to comments right because partly because that's less visible in YouTube when you're just scrolling through things yeah which is unfortunate because that's where more substantive discussion might happen yeah but I don't know it's certainly less than ten but it's it's it's an unknown unknown because I don't stay exposed to it right for someone who's never seen your videos before and I don't think there are many people listening to a number four podcast who won't who's in your videos before but just in case how would you explain them but to say I'm a taxi driver you know let's let's let's roleplay this I'm a taxi driver you get in the taxi yeah I'm like hey man what do you do what do you how do you answer that I I will often say I run a youtube channel about man do you go with math straight away or do you wait or will you just say I run a YouTube channel and hope they don't ask more or I go into math because I don't know that satisfies the intent of the question I know sometimes people want to just shut down the conversation about what do you do but yeah more than not someone actually wants to have a conversation so God say give them something to work with so you say I run a YouTube channel about oh really oh how does it what does it do like are you in the videos or what are the videos look like how does it work you really the first question is what level of math like is it for high schoolers or oh do you make like tutorials to like health through homework yeah or like oh is it like you know you put out one a day of like homework health like boy do I wish yeah and at this point even though I've been asked so many times I always just falter on who is the target audience I don't know yeah so I try to say if I'm doing a good job I want the video to be accessible to a curious and smart high schooler but still interesting to like a PhD student yeah I don't always do a good job and those are like hard topics to find but that's the goal and then I might give them some examples where I say you know a lot of the things would probably be categorized as like college math in some way it did series on calculus on linear algebra but I also try to do every now and then things that are not math per se but can be a gateway drug into it like how does Bitcoin work or what are neural networks but your videos have got a very distinctive look and the way you make them is like the thing isn't it so do you go it how do you explain that yeah I perhaps that's where I should start as I should say the thing that I try to make the channel do more than anything else is look visually distinctive and put animations first in the explanation rather than making them a supplement to the explanation like if I'm thinking of a topic it's better if I think this is the core visual around which the narrative will revolve rather than writing a script and then later thinking hmm what visuals will I put to this I am definitely a big advocate also of while I'm animating things letting what I discover while creating the visuals change what the words will be I know some creators they'll do it the other way around where they like they lock down the words and then they're just putting visuals to it because they don't want the scope creep that comes from that change which maybe I'm a victim of because many of my videos are 20 to 30 minutes but hey that's what you get yeah yeah if someone's really curious at that point and about like what I mean by trying to put visuals first depending on what mood I am or what environment we're in I might just pull up pull one up and show it cuz you know I don't have the thousand words that match that picture necessarily it's interesting like you say oh I'm not a filmmaker naturally but the very thing you're saying is actually when I was taught to be a filmmaker at the BBC by the guy that came in like did a lecture to us and that the one thing that he taught us was to do exactly what you're doing and it slipped the pictures the visuals in this case it was video and film both your cases animation was tell at the Chiz dominate the script and the script is almost the last thing you write when you've got all your pictures and you put them down you see what how the story looks visually so you know maybe you are were you thinking like a news journalist at least what else did they teach you I should learn more yeah that's interesting the some of the things they talk probably wouldn't be useful to an animator but so you when you've got an idea presumably then before you even write a script you'll just you'll just monkey around with animations for a few days were you and look what happens and what's pretty and what's nice and what what's interesting yeah if I if I am a head of things and on the ball I also try to do sample lessons with people I'm doing a project right now on-quarter neons which is kind of a weird and difficult topic I've probably done 12 sample lessons with various people who are test dummies so usually friends or sometimes if I the other day actually like ran into someone I just hadn't seen forever in a cafe and we were just chatting and rather than doing the traditional what have you been up to what's going on in life you know after giving through a little quick I said hey can I try to teach you said do you have a half hour yeah and that I mean it's fun for both of us I think because I knew he was at least somewhat into like technical topics I also teach I have a couple like private students that I like dude or now and then I'm very on and off about it because you know it is with like scheduling but I think that's important to keep up some of the topics I do on the channel are conducive to using them their high schoolers as sample students some of them maybe less so but when it's possible I try that do your two T's love having a famous YouTube so everybody is there tutor I think well so I mean I've been with him for a long time long before the channel existed so I think they're just sort of amused from the sidelines about the fact that I went from just being like the random dude who would occasionally come over and teach them things to like I guess there's the channel associated with this now because it started much young and we just they're more like cousins at this point really that was never something they colored the relationship how unprofessional my leaving that on for shame Brady for shame sorry let me turn off these trial lessons you do with people like when you are test driving your next video are you trying to stick vaguely to the script that's in your head or you just like you know back of a napkin two guys talking over a pint and then later on you know it'll become the script you or you kind of test driving how you think you're gonna do it and hate the lines you're gonna use and things much more back of the napkin the goal is to find the things that are confusing that I didn't think we're confusing right that's that's the end goal and so who knows maybe if I was on top of my game I would come with better prepared articulations of the points but part of it it's a forcing function to actually get the writing done right because it's hard to write things but if you're speaking to someone you will I would put words and sometimes you uh put some words anything oh yeah that is the way I want to phrase it right so are you using the animations at this point are you pulling out a laptop and trying to integrate that or sometimes usually not because it's earlier in the process so instead people have to deal with my terrible drawings so yeah there are definitely so there's the phase of letting people inform what it'll be and then while I'm animating and like put together stuff then that also helps shape what the words will be so those are usually two distinct phases sometimes like I could I don't know like I might even try this with you after we record I have a couple animations for what will be a follow-on project um that I could just like show and it would be interesting to see like reaction or what questions come about yeah but that's that's a sign that I'm ahead of the game more so than I usually am so as your enterprise is expanding and obviously it's becoming you know pretty successful channel and people want more and more from you are you like are you turning it into like a business with employees and things or is it still just you slaving over a computer or very short answer I did I tried it a little bit having other people on board just to kind of experiment with that and I think that could have been a proper and successful path if the goal is more content and if the way to do that is with multiple channels where you're giving complete autonomy to the individuals what I found is it's actually very hard for me too often hard for me to articulate what I don't like about something and when you're doing that in your own head that's totally fine you can say no to yourself 20 times and not sacrifice any social capital I felt like this constant divided on I don't want to rob someone of autonomy if presumably you found someone because they're able to create really good things yeah but I also have a particular character that I think is in the channel and I don't know if the smartest thing for the channel would be to compromise that character so you think like the videos a lot of and I would agree with this by the way a lot of the videos are made by your personality they have to be mostly made by you or they wouldn't be what they are I do believe that and I feel kind of weird and mildly egotistical to even say it out loud because it's like oh I you have such a great personality that like your content will be better than someone else's like not necessarily it's just that's what it is and that gives it a certain consistency the analogy I kind of made to a couple people when I was talking that is maybe tortured if JK Rowling when she was writing Harry Potter books after the third book said like hey this is going pretty well I've got more funds now you know I could I could bring on some of the world's greatest writers we could have a hundred Harry Potter books there's something wrong about that and it's hard to put your finger on why that's wrong there are better writers than JK Rowling absolutely there would be more Harry Potter content there would be niche fans who would love a hundred Harry Potter books and yet there's something that's just not it would have lost its magic no pun intended again it feels kind of weird and egotistical to say that because they go your eyes are like the Hope Diamond your videos are like Harry Potter like that's not necessarily what I mean but there are difficult - I wrote a whole like patreon post sort of trying to express my thoughts on this because I wanted again like when you're forced to articulate something that clarifies thoughts yeah yeah no no I understand you love people people will say the same thing to me they say oh you should you should you know they know I did collaborations with various universities and they'll say oh you could have hundreds of people doing what you do with all the different universities and I'm like yeah yeah I could but like I don't know I feel like my videos and my videos and I ask the questions and make them that way and that you know I want them all to be like that and I'm sure people also oh you could hire an editor yeah but I mean you tell me but I would imagine a large part of what goes into the creation of your work is making the choices for what is interesting and it's not just this rote grunt work of oh you're editing it you're cutting it down no that's the substance yeah yeah and when I do get a little bit of editing help it'll be like oh no you can't cut below no no I thought that bit had to go and I'm like no that was the that was the one thing that had to stay in the video so there is that there is that there is that tension but then you know you are one human and it does it does limit what you can do also the way I just thought about this is I previously had had thoughts okay I just want to produce a ton of content if I could even have like one video per week if I could have like essence of blank series and all the topics of math that would be great it kind of backing you up and saying that's not necessarily what I want I want there to be more math content I don't think the best way to do that is for it to all be under one umbrella but to like inspire people maybe even provide them with the tooling for it shout people out when they deserve it and is appropriate like all of that will help there be more math content my role should just be to spend as much of my own time not on anything managerial but just on like creation of things that I think wouldn't be created otherwise that means there will be less content I was talking to you before recording about how I'm feeling antsy but it's been 40 days since I've published a video part of the reason for that like the project that's coming up I feel really excited about and it'll be distinct I can almost guarantee it's a project that wouldn't have happened if I was like running a small company cuz it just it would make zero economic sense to like throw my time into it that way but maybe there's a certain beauty to that that like this is the kind of thing that in another instance of the world wouldn't have existed maybe people like it maybe they don't but the more you do things like that you know that's the that's the only way you'll expose to yourself to creating something that people find genuinely special do you put the reason you do the videos down to like some altruistic reason obviously it's your business and it's your career and it's how you put food on the table is that what it is to you do do you we wax lyrical about how you want to inspire the next generation of mathematicians or is it just about like a passion to get it out there what's kind of is there something like that motivating you or is it just what you've fallen into or um I mean I think there's some YouTube creators sort of there's like different generations of educational creators you know I think there are some in like the my generation so to speak that viewed it as a job this is what I will do as a career to put food on the table and obviously as you say that some component of it but you know you were kind of talking that way in some ways you know it sounds like you were making calculation you were saying I think universities have got this problem and like there's a problem going down this path and you kind of identified I Wilson career path I did I didn't think YouTube would be that career path actually like this is part of why being a part of an organization like Khan Academy feels so alluring I thought oh this is great I can have my YouTube presence be an aspect of my like online identity that helps me move from one place to the next but like yeah math is nice like it wouldn't necessarily work out I thought it would be much more akin to you know how like Katy Mac being popular on Twitter probably helps well it's hard to know depending on like which academic environments but that's not a bad thing to have going into doing something like slightly different but you know obviously at some point on my mind that was like a path to address your original question do I wax poetic about the influence it might have on young mathematicians to be I mean I do and there's an element jeez it's hard to articulate because it's hard to articulate and not feel like to sound like an idiot right because here's the thing there's a way that I'm very sincere when I say I want to inspire more people to love math I want more people to self-identify as loving it whether that means fanning the flames that already exists which with a channel like mine or yours probably as 90% the case or in those rare special cases sparking that flame to begin with I'm sincere when I say that but it wouldn't be the full truth if I didn't acknowledge part of the reason I make the videos I just like making them I think there's an element of enjoying learning something and if you want to explain something to someone else that's what's gonna make you learn at the most it's purely self-contained purely in my own world the pleasure and value that comes from it and that if no one else was watching them and or rather if as many people were watching them but somehow I could put on an omniscience cap and know that it had zero influence right like if the ones that were gonna love math loved math the ones that were gonna hit it didn't see it there was no influence yeah I would still really enjoy making them for those more selfish reasons and I don't you know it's hard to know if you can break it down now it's 40% this 20% that like anything in life you know the motivations for doing something are extremely muddled and it's hard to be honest with yourself about where they come from when you're going through the process obviously it's quite a long process making one of your videos because they're so long and I've got so much animation in them and they're just so dense and you've thought about them so much of all the steps in the process from the sitting down talking to people to the the initial monkeying around with the animations to see how it's gonna look to writing the script to the final push when you're actually making it like is there a part of that you don't like like just is that final push you know that final week where you're like okay now I actually have to make it is that like a slog or Esper that's the but that's the best part so like the animating that's the worst part for me so I animate things programmatically and I love programming and I think it's here's what I like about it there's just you know what needs to be done it's kind of grunt work II but there's tiny little micro problems to solve but they're not too hard so like a lot of people disparage the notion of grunt work that's that's the most relaxing and get into flow kind of style of things the part that will be the most uncomfortable is writing it and especially if I like haven't done sample lessons or if it turns out I wasn't clear on what the idea would be that's the part that's the most creative but it's also the most painful and I think this lines up with a lot of other my quote-unquote creative work is the thing that people like to think they enjoy ah this is the like I'm creating a book writing it in some way it's actually a very painful process and then the more rote things if it's like mowing the lawn or something like that it's actually quite enjoyable because you know you're making progress it's very clear how much progress has been made and it's easy to get a little bit addicted to that at least I think maybe that's a personality type tell me about like the ten minutes before you make a video go public and that ten minutes after are you strike me as a personality type that would not enjoy that ten minute period of pressing the button and because you're finding out how its first received for if you've made some whopping mistake or you know I'm not as much of that personality type where you know you get neurotic about it certainly maybe I used to have to get more butterflies in the stomach as if you're about to give a talk when you hit publish which is silly because you're just in a room alone these days I'm much more you know I try to early release it to some people so that they can catch mistakes so there's it's not a discrete moment of it was unpublished and now it's published that helps a lot right then I hit it and you know I I get a little addicted to reading the comments and initial replies so often it's it becomes a very unproductive day right yeah like if I outputted things as frequently as you did I would never output anything at all right because nothing would get done yeah I think it's actually fun I enjoy that part I also like I enjoy public talking and that sort of thing because you can get energized by that yeah I can see why I would come across as that type maybe getting like the more nitty gritty you get into in the details of making a video and the more time you put into it it feels like that's all the more weight that goes into that moment of publication you are obviously what you're obviously quite good at mathematics you know you got into Stanford and and that sort of things so you obviously have like a talent for mathematics does any part of you wish that you become a mathematician do you ever feel like you're a sports commentator and you wish you'd been the quarterback like you wish you with the guy solving the Riemann hypothesis I mean part of me is just aware that I'm not that good I think there's some things that I'm quick on I think there's some things I'm really slow on sometimes that's to the benefit because understanding something slowly can give you something better than understanding it over a longer since maybe part of the reason I never actually did follow through on the traditional PhD path as much as I would like to claim ODS and cynicism about the university system and it was a calculated choice an element of that was an insecurity knowing that there's just a lot of people way better than me I don't know if my predilection for math is well tailored to research as opposed to trying to come to clear understandings have already known things but does that make you even more jealous of those people and wish you were one of them or you're just quite comfortable with your luck like like cuz I couldn't do any of that stuff but I spent all my time with all these Nobel Prize winners in fields medalists and that and like I have like and like a kind of envy for them I'm like oh good on you that's like that's the real work you know I'm just here I'm just here explaining the greatness of others and like even though I know I couldn't be great I still wish I could have been yeah I feel that I mean I definitely do how cool would it be to just actually put out a rational research and feel like you're solving problems other people haven't I also in a way that is silly if I'm honest with myself can get just intimidated by mathematicians when I'm talking to them they're all nice normal humans but it's a little bit of an inferiority thing knowing you you have a background and a patience with the subject that I don't have and maybe haven't displayed it the same way so yeah I feel that what's next what's the next like what deed are you a plan a lot that or do you just fold it's you know it sounds like you've fallen from one thing into another in some ways a little bit I mean I've got along with I have the list of topics that I intend to cover even as people make requests maybe it goes on there as I stumble across something maybe it goes on there every now and then I Reese wart the list but the way it goes you know someone says oh let's do this thing you do that thing or you come across some random little thing often if I've just done a very big project I want to sort of exhale by doing a smaller one but is it all online video if you're not like do you think that's it I'm a filmmaker now what do you think no you know this online video is gonna go the way of the dodo and I need to be making three-dimensional goggles things where I want to write a book or like have you got plans be on video or you think that's just your hands are full now yes I do want to do things that are not just video there's one vague possibility I won't talk about it because it's enough of a vague possibility but there are things on the horizon that I think you definitely want to spread yourself away from video per se the one I'm working in right now that I was talking about you through before is it's like more than just a video it's gonna be a interactive video type experience that is different and if people seem to like that maybe it makes sense to expand that out more and rather than choosing a different existing medium we forged the way in a new type of medium or maybe people won't like it and it goes nowhere fun to experiment yeah I would love to do more writing not just about math but in general but writing as low as you know maybe that turns into a book at some point maybe not yeah I think I I would I would be disappointed in myself if you fast for over two years and the only thing I have going on is online video when you were starting number file I kind of want to turn that same question you were asking earlier about the influence you wanted to have was that a thing on the mind like inspiring young students getting more people into math or is that like the spirit of the question is to know to what extent are other people like me in their motivations yeah like to you in particular Geist I mean no I I was just I was just talking to a bunch of math teachers a few days ago so I got asked about this so the question is fresh in my mind I guess I don't have like the loyalty and the history with math that you do so it's not like you know this is my this is my passion that I want to push the Barrow for with meet with numberphile and with all my channels it's never about trying to advance the subject it just so happens that these are subjects that I find really interesting like I find mathematic good at it but I find mathematics very interesting find chemistry and it's all science interesting and as just like a storyteller and a journalist I just have a compulsion that when I find something that I find interesting that tickles my brain I just want to tell other people like I just like it's like an addiction storytelling and sharing cool stuff is an addiction and you know I can't come home and tell my wife about every interesting thing I know because she finds a bit boring but luckily I live at a time when instead there's this piece of technology that means I can go and make a film and tell a story until you know thousands and thousands of people and if that makes someone want to be a mathematician fine if it makes them hate mathematics I'm surprised no I'm not sure I don't feel like and I don't feel like I have an agenda to change people's lives I just want people to know cool stuff a really good example of that that isn't video was I once went down into the Bank of England's gold bullion vote which is under the streets of London in a really busy part of London it was the first time cameras had been allowed in there so it's a really rarely sane thing it's really pretty amazing and I went down there and filmed it and whatever and then came back out above the street and like you know I went to go and have lunch and go to Starbucks or whatever but I just felt like there was like I felt this adrenaline and goosebumps cuz I just seen this um you know four hundred billion dollars worth of goals the most amazing sight I'd ever seen with my eyes and I just wanted to go up to people in the street who were just walking along on their phones and going about their business or the crowds of London I wanted to grow them by the collar is this amazing thing and you don't know what but you have to know it mm-hmm and I think that like that side of my personality is why I make the videos when I when I sit down with the mathematician and they're explaining something to me and they say let me show you this cool thing and let me tell you this cool fact or piece of trivia and it's something I understand like it just sends like I get these chills down my spine and I can't wait to make the video because I want other people to experience those same chills I don't care what job they do I don't care if they're watching it just for fun on their lunch break or if they want to if it makes them go to school I feel really good when that when they say and I'm sure you get this all the time I feel really good when they say I'm gonna study mathematics at university or I'm I've changed my major because of your videos you really inspired me that makes me feel super super proud and happy but it was never why I did it and it was never what I'm thinking I'm never I'm sitting there making a video thinking well this is gonna make people want to be mathematicians for sure I'm just thinking are there this fact about pie is gonna knock people's socks off what's funny sometimes they don't get those messages like I'm gonna study math as a result I sometimes I'll reply with this so sometimes I just think it in my mind study computer science at least as well but I don't know if you should spit I don't know if everyone should study math I think they should like it and take some classes in it I don't know if like the math major is actually the best way to spend your college time and I would feel much more comfortable telling someone to study computer science and take as many math classes as you feel comfortable with so every now and then like someone will also email like I'm really struggling on deciding between like math you like your videos inspired me but like I also like programming I also like physics and in that case like do the other thing also definitely don't listen to some dude on the internet what do you like I don't know your situation but yeah I don't think it would be good if everyone wanted to be a mathematician because the cold hard truth is it's not it's not useful enough like pure math in and of itself isn't useful enough for too many people to be doing it I'm gonna make that statement I don't know if I stand by it I think I do okay well you can retract it at a later date there's an Asterix on that one we can agree that unless there's you know artificial general intelligence feeding us all of the food we want in the world like there is a a point at which there are too many mathematicians like you don't want a hundred percent of the population doing it because then no one gets fed you don't want even fifty percent because there's just other more interesting things to do for math sake also I think you know like in the same way that the Manhattan Project pushed forward physics because it threw a lot of otherwise only on the blackboard theoretical minds into a circumstance where look this has to work yeah right the atmosphere might blow up if the calculations go wrong here so don't mess them up yeah I think that is good for physics and in much the same way I think fields tangental to math are very good for math and I say that is someone who gets very turned on just that's not the phrasing I want a very take old by math for its own sake that's not necessarily applied but I the more time that passes the more the more weight and legitimacy I think the tangential fields deserve in its place I also don't think math should be this mandatory class that you teach at every year of school all the way up that feels I integrated to me I think programming should be that instead I think math should have the role science where it's there a lot and especially as in elective forms and I think that exposes people to actually feeling passionate about it in a way that it's hard to feel passionate about something if a school is forcing you to do it do you think society needs to be more math literate like do you think it's bad that people don't understand mathematics better like you or do you you know doesn't matter a lot of that math literacy rhetoric I don't necessarily buy people will make the case in statistics you have to understand the statistics that you're reading from the news but the fact is even if you understand it pretty well you still have to rely on like the good faith of the journalists to have dug up like the right information to be showing you because maybe if you're an absolute like professional statistician and you have access to the right data sets you can cross check at all and that's a level of literacy that will make you view the articles with the appropriate skepticism but I don't know if zero to ninety percent actually gets you that much more more of a truth seeking place in politics and in culture then it would just to actually have a good journalist certainly with a lot of other math like I don't think when it comes to calculus like why should you know calculus most people don't need it most people don't need group theory I think these things can add value to your life in terms of the way that you think so that seems good if they want it if they don't want it don't shove it down their throats make sure it's available to them if they if they express even an inkling of curiosity in that direction you know the phrase like a little knowledge can be a dangerous thing I think that definitely falls in you get someone who's taking one statistics class and suddenly they're looking at every news article they read and they're like ah but that's not what that number means it's like even if it's not I don't know if that's brought you any closer to the truth [Music] people's who study math should do more to study storytelling and like performance art related things partly because what a lot of people who go into math end up doing is teaching and conveying it in some way so being able to tell a story actually seems important and being able to be comfortable in front of a crowd also feels important and that's certainly if you fall into the stereotypes about the kind of students who study math that's not the default option to take an improv class or to go you know learn short take a short story class by opting in rather than having that force to you but I think that's very important of all like the STEM disciplines I don't know if you would agree with with us or not but I feel like mathematics is the worst at outreach as a whole it of like compared to like compared to physics and chemistry and a lot and engineering even like math is like the is the worst selling itself as a whole do you agree and if you do why do you think that isn't if you don't okay I have no idea and the reason I have no idea is because my circles are all around math communication by virtue of like what I do so my exposure is hey there's a lot of math outreach like this great book was just written what are you talking about yeah but so then I know okay I have to put a break on that but I have no idea how much I should shrinker or grow that skewed perception yeah I do think that most like math lessons and math textbooks are I would say are objectively less approachable than introductory physics textbooks and science textbooks because there's certain cultural tendencies around how to describe something where logical precision naturally takes precedence over pedagogical clarity for example very common to open a textbook and see the definitions of things after all how else could you start in order to talk about the things you must know how they're defined but that's a bit like teaching a baby how to speak by giving them a dictionary it's actually quite intimidating this is part of why Wieck wikipedia is so unreadable for math is that unless you have read enough to understand either the corn nuggets of those definitions or the idea that you're not supposed to understand the definitions yet that that will come from examples you're immediately turned off whereas I do think like computer science partly because it's such a young field doesn't have that as the same cultural problem and there's much more of a standard for motivation behind a given difficult topic before you get into its meat that's a good observation about Wikipedia because I so often find myself going to Wikipedia for help when I'm researching a subject or editing a video and it is no hope to me ever and in mathematics it's horrible yeah like I find some value from it and I feel like the only reason I do is because I've sort of learned how to read it yeah actually on the cue of videos that maybe this conversation will help push me in the direction of making it more like how to read a textbook because I don't think you should read it linearly like a not like the way you would read a novel and I do think there is a notion of getting better at that or worse at that for example start by looking at the exercises at the end of the chapter because those give you a sense of what kind of problems you'll be able to solve also it'll give you a sense if you don't understand those exercises because they all use the jargon that was developed in the chapter that entire subject for the moment is just like getting you out of a hole that you've dug yourself this happens a lot in math you define a whole bunch of things like what is a topological set and then you solve problems about the nature of topological sets and it takes quite a while before you get to a point of who cares about topological sets so if you if you notice that you say hmm this chapter isn't gonna be where I know why this is important and that's a good thing to know ahead of coming in there's another time maybe you see an exercise that's understandable without the jargon and that's a sign hey this means I'm learning tools that are used in a different way and that really shapes the way that you look at the whole chapter don't read the definitions first look at the examples after that when you see a theorem don't read the proof view it as a personal challenge like a bunch of little things there that kind of took me a really long time to actually stumble on I'm sure there's other good tips that just made me slower in learning math through college I'll tell you what I'm taking away from this not that people should read textbooks differently obviously but they should be written differently maybe that's your thing like maybe that's I would love to read a math textbook that you did maybe that's your long term project if anyone out there makes math textbooks get in touch with Grant Sanderson or grants understand depending on where you're from and get him to write your textbook would you write textbook it seems like a lot of work but I I can't rule that out that would be fun turn it on its head yeah questions at the textbook the untaxed well that's it for today but if I may do a bit of a post-show debrief firstly and most importantly if you've not yet seen a three blue one brown video make sure you do just put three blue or one Brown into your search bar of choice grants not hard to find and of course I'll include some links to his stuff this podcast is made possible by help from the mathematical sciences Research Institute in Berkeley California but this episode was also supported by Maya sound and they're also umber CLE now they're not here to sell you anything but they do love sharing with people about their research and latest developments from the labs so if you're curious a good place to look as their website Maya sound calm and then just find your way to the news or about sections of the website the Wikipedia page about my sound is also pretty good actually I'll include links in the show notes now the numberphile podcast we'll be back very soon you're probably aware this is a bit of a new thing for us and you can give us a real boost by doing all those usual podcast e things like subscribing reviewing rating just tell your friends about it it really means a lot especially at these early stages it'll help

You said you will sometimes explain things to better understand how a video will work. I want to volunteer to review such explanations. So I guess if you are looking for someone in the freshman CS major, pm me.
