My private calculus tutor, Jesse, told me about 3blue1brown about a year ago at this point. I am still thankful to this day that Jesse saw the burning interest in maths I had, beyond my horrific struggles, and wanted to encourage it further by influencing me to watch Grants work. It was life changing for me. While I am still struggling at calculus; it will likely take me 4 years to get through the calculus sequence + DiffEq when it takes most people 2-2.5 years. Grants videos, and some others, helped me to see what's beyond the knowing and see the understanding which is what made me double down and not quit.....I'm over 40 BTW and sticking with this has been the biggest soul search in my life so far. People like this, who make this content, really help more than they will likely ever realize. Thank you Grant and Brady

[@beanbag_VEVO]

34:44 thought this was a hello internet episode for a second, sounded like cgpgrey there

[@devinmurray4984]

I think the first 3b1b video I saw was "What does it feel like to invent mathematics." I was in my 3rd or 4th year in a mathematics PhD program at the time and was just starting to write my first results that lead to my dissertation. I've really adored Grants videos and have been watching them since. I make sure to tell my students to watch at least one of his videos every semester. As for your predilection for mathematics not being up for research, eh, I doubt it. Research is not particularly more than understanding already known things. Novel research is what happens when you find answers to your questions, and you also happen to be familiar enough with the literature to know the problem was open before you found the answer. If it's in any way nice to hear Grant, I, a young but professional research mathematician, find mathematical value in your videos. I'm still really trying absorb your Fourier analysis videos. I still think of the Fourier series in terms of topological groups and homomorphisms, and I've still not been able to distill it down to explain it to someone without a familiarity with group theory and measure theory (So I don't really understand it yet). Keep up the good work.

[@markC-888]

Though I very much wanted to learn more about the person behind 3blue1brown, this interview surpassed all expectations. It was phenomenally interesting. Kudos!

[@sketchyAnalogies]

It’s not egotistical to think that way. Your work is not necessarily better than that of others, but it is yours. You built your channel on your personality. Your viewers like your videos because they are made by you. If other people work in them then they are not made by you. Love both of your work. Keep it up. - a high schooler curious in topology, tensors, E&M, and math in general. Thank y’all!

[@ThePharphis]

Grant raises a very useful point regarding understanding of statistics (and other things, in general). We really, really place trust in institutions for being honest (probably too much trust) and even when facts are cited accurately, they can be misrepresented (even unintentionally) for a variety of reasons.

[@codahighland]

I appreciate the slower pace. Not because I like it slower myself, but because I have no problems kicking the video up to 1.5x or 2x and following along at the pace that I find comfortable myself, but someone who talks too fast can't be slowed down with any sense of quality. It gives the viewer more control.

[@benthayermath]

Brady, You mentioned that your goal in making these videos is just to share cool stuff because great ideas are contagious, not necessarily because you were attempting to inspire people. I think it's worth mentioning at this point that you have inspired us, even if that's not your primary goal. I first discovered your channel in high school (in the U.S.) and I was fascinated by these crazy problems and ideas that I had never heard of in a math class, before I even knew I loved math. I found them absolutely addicting! Now I'm a good way through a math degree, and I think you would want to know that your channel was a contributing factor. Thanks, and keep up the great work, -Ben T. p.s. -- I love the collaborative spirit lately in the world of YT education; it's very exciting! The podcasts have also been great!

[@jamesrockybullin5250]

32:55 Wow this guy is an expert interviewer. Steers the conversation right back.

[@TheHumbleSpoon]

I disagree with Grants view that CS should be taught mandatorily in schools and that mathematical subjects such as Calculus should be taught as electives. As was discussed in the video, the quality of math learning resources is fairly dismall as far as textbooks and online resources such as Wikipedia are concerned. CS, on the other hand, has managed to churn out great resources for self teaching programming skills. If someone wants to learn math after secondary education, the barrier to entry is massive because the initial learning curve is fairly steep, whereas someone wanting to teach themselves CS will not only find a wealth of well made materials, but those materials will be made for self study. Because of this, Math needs the helping hand that school will give you whereas CS really doesnt.

[@donlansdonlans3363]

There are also tons of resources for math

[@donlansdonlans3363]

I personally think that there are more resources to learn math than cs, there are a lot of resources for learning programming, but beyond that, there are less resources than resources to learn math, yeah, programming is important, but it is just a tool used to implement algorithms, computer science is not about programming, and i think schools that claim to teach cs shouldnt focus so much on programming, or otherwise they shouldnt call their class computer science and directly call it something like programming etc

[@VikeingBlade]

School won't give you a helping hand, though, other than making you not have to learn the Pythagorean Theorem because you had to memorize it

[@goclbert]

A lot of people in science professions end up having to learn some math later in life and while they may not become experts, online resources certainly help. At least up to the point of multivariable calculus and linear algebra.

[@aufdermitte7143]

Computers are ubiquitous nowadays, undeniably having proficiency with computers is far more important that knowing calculus.

[@MK-13337]

I was always the kid that didn't like math in school but I was good at it nonetheless. In high school I saw the light (so to say) and fell in love with math (only finishing with average grades because school math is boring even if you love real math). Now I'm a mathematician. It's a wonderful subject but before uni/college school does it a disservice.

[@leophoenixmusic]

In agreement with Brady's point, as a viewer, the thing I really like about Brady's and Grant's videos is the steady pace and long format. If anything I’d rather have longer Numberphile videos! Although I guess that’s what Numberphile 2 content is for :P Also I agree with the idea that Brady and Grant are almost at one with the channels they represent. I just couldn’t imagine what Numberphile would be like without Brady behind the camera. It’s Brady's personality and genuine interest in what he’s making which makes the channel so great.

[@tetsi0815]

1:00:00 I'm probably not very representative for the majority of people (I studied computer science and am generally interested in math) who turn to Wikipedia to look up a math concept, but I find it interesting that you think the english Wikipedia is horrible at explaining those. As a German native I naturally looked up things in the German version of Wikipedia and generally had to start looking up words from sentence one. Later I found out that the English version of a math related article is in general much easier to understand, less convoluted and has much less jargon than the German one.

[@xavierstanton8146]

Nowadays it's much easier and more trustworthy since scholars look at the articles.

[@NoriMori1992]

Wikipedia articles need to be able to explain things in a way that an educated layperson can understand, not just people who have some post-secondary background in the topic, or have already read a bunch of other Wikipedia articles in the same general topic. Most English Wikipedia articles that I've read utterly fail on that front.

1:01:00 Heather A Moon published a book about Linear Algebra that I found quite readable. It was the only math textbook I could sit down, read, and get a decent understanding of what the topic was. And it uses the same 2 real world problems through out (CRT scanning and Diffusion welding), slowly fleshing out each as you learn techniques to work on them with.

[@gaussianvector2093]

[@nidhinbenny7975]

Its a great point they make about reading wikipedia math articles. Actually I find that online content regarding physics, maths, chemistry can all sound like gibberish until you reach a certain point. For me, once I got to around my last year of undergrad engineering/science was when the articles online really seemed to open up and make sense. Suddenly what used to seem like gibberish was starting to make some sense (especially in maths). So for any student who is reading those things online and wondering if they will ever understand, just a message of hope: hang in there, sometime towards the end of your degree, it will start making sense. This may be little help in doing that assignment that you need done now, but at least at some point you will understand and thats more important than any assignment.

[@HebaruSan]

Definitions (and examples) in a text are also essential so the reader can scan back and re-read if they realize later that they didn't understand something. Roger Penrose's _Road to Reality_ illustrates this quite painfully by having almost no definitions or examples; if you get lost, there's no way to catch up, rendering the book mostly unreadable.

As for the last part, I found wikipedia super useful for me, learning as an undergrad. It sort of sets up this scaffold for me, of different kinds of objects and the connections between objects in kind of a vague way, which makes it much easier to fill in when I actually go and take a course on the subject. It gives me a sense of the landscape at a high level. I think you need to be very comfortable with being in a state of confusion, or knowing that your knowledge of these things is extremely unclear.

[@wildgoosechase4642]

I always thought that Grant was talking about the dominant and recessive alleles of eye color, and his channel name was about the proportions of offspring with each color from heterozygous parents. Of course, that would mean blue is the dominant color while it is in fact brown that is dominant. (of course, eye color isn't always a case of complete dominance, as can be demonstrated by Grant's eyes)

[@Gribbo9999]

My northern English is closer to American "Grant" than the southern English version . As usual, to southerners, English stops at Watford. No matter, with any pronunciation, Grant is a genius presenter of maths.

[@danieljensen2626]

I think more math literacy would be good because of the opportunities that come with it. Many high paying jobs like STEM jobs in industry require a high degree of math literacy. And of course not everyone can or should work jobs like that, but there are strong trends that well educated and math literate people are much more likely to have children who are well educated and math literate. So even if you don't get a job like that your level of math literacy can have a significant impact on career options for future generations. This is especially important because a lot of low income people are less likely to have much math literacy, which means not only do they not have access to many jobs which could improve their economic situation, but also their children are much less likely to achieve math literacy and have access to those opportunities. So more math literate social groups are improving their situation while the other groups are getting left behind. I think if everyone had a decent degree of math literacy they would be able to pick a career more based on what they wanted to do rather than just being stuck with something because the options they might be more interested in are out of their reach.

[@consultant_of_swing2146]

Found it interesting that Brady went with "math" rather than "maths" for this interview. Good journalistic instincts, as always.

[@avi12]

Pure math itself isn't quite useful unless it's about computer science, but instead, the process of solving a problem - that's the important bit. That's the key to solving small & big problems - breaking them into smaller steps - exactly what you're doing in math.
