"This is the amazing thing about kids and by kids I mean PHD students they don't know what hard"
I want to call that the SiFi amorphous condensation visualisation ability. (?)
I taught my 7yo niece to count in binary. I framed it as "I can count to a thousand on my fingers". Then I put stickers on each finger with the numbers 1, 2, 4, 8, ... and showed that you can make any number by adding up the fingers that are touching the table. She enjoyed telling me which fingers I should put on the table to make different numbers.
I love that aside from the hazard of your niece trying to count in binary on her own and learning that other people seem to have Strong aversions to the numbers 4 and 5...
Great conversation! Regarding communication between disciplines:
When I was a PhD student in music theory, I taught several undergraduate music theory courses. A senior math professor asked to sit in on my class because he liked music. For the first few weeks, he was catching up on the music jargon and some notational issues. Once he understood that, I was amazed at how insightful he was at looking at music theory problems in different (and often more efficient) ways.
Similarly, I don't have any formal training in math beyond basic high school classes. However, I took a PhD seminar on music and computation/math where we analyzed and composed music using various math techniques (some stats, combinatorics, etc.). It took me a while to get used to the jargon and notation of math and computer science, but once I did it felt like a whole world opened up, and now I work as a machine learning scientist for speech and audio understanding.
I think there is so much different disciplines can contribute to each other, and I love that both of you and others are calling for better ways of stepping into and understanding jargon that prevents so many people from understanding a topic.
Whoa, this is so great !
Can you please elaborate how exactly you picked up the relevant math and stats/ ML skills ? For instance, how were you able to take classes on Statistics, ML, Linear Algebra in order to prepare for such a change of career ?
@@SayakKolay I was very interested in math and music, so I learned a lot of math independently online. I also had a music professor who also had a math degree. He taught me a lot and pointed me towards several resources.
Perhaps the biggest thing is that I learned a ton of math by learning to code. A lot of things became very intuitive when I wrote them in code rather than mathematical notation.
Also, with high-level programming libraries like sklearn, keras, and pytorch, you can build some basic ML without knowing all the math. I did that and then learned the math behind all the operations once I had some intuition about how things worked. It turns out that ML doesn't really require very advanced math, and modern coding libraries take care of the details so you can focus on the big picture.
Your story is similar to mine and inspirational. I had that first exposure during undergrad software engineering classes.
Grant is actually a great interviewer, how he confronts the earlier answers with future points Alex make to formulate the questions is so engaging and fun to watch, had me hooked trough the whole episode, im loving this podcast keep it up
This is great! You making podcasts is the thing I never knew I needed, thank you for creating such awesome content:)
This is amazing, probably the highest quality math-centric podcast I've seen so far!
This was an absolutely great conversation and kudos for the podcast initiative Grant, Thank you! If I had access to this kind of content 10 years ago when I was in undergrad, my choice of curriculum would have probably been different.
Such a fantastic interview! Thank you for this, and for all the other amazing videos on your channel.
As a phd student in math this is EXACTLY the content I was looking for. Ty!
Thank you so much for this Sir! Would love to know more about such inspiring people from the educational domain
For my Master’s thesis, I had to look at a couple of his papers. Was quite a shock to see someone I ‘know’ on this channel!
Absolutely fascinating, can’t wait for next week!
I love the podcast and am excited for the coming episodes. Would it be possible to add chapters to the video and the audio version? These would be immensely helpful and appreciated :)
I was just binge listening to podcasts on Spotify in search of something interesting and you drop this! Looking forward to listen to this before bed :)
I'm a senior in undergrad. I remember having to learn LaTeX freshman year and proof writing at the same time. But never have I heard of Lean. I took a comp. sci. class that introduced me to Standard ML, my first functional language. After checking Lean out, I'm super excited to try and work with it as I round out my senior year.
are you from CMU?
Whats lean ?
So excited for this new, fresh content. Godspeed, Grant.
Dear sir Grant , can i just say that i love you? Thanks a lot for your gift to mankind , the channel 3blue1brown and this new podcast too! You are the most inspiring educator i have ever seen .
Finally a dedicated podcast! Thank you!!!
This channel exists since 2011 and after 10 years you uploaded your first ever video. See you all in the next video in 2031!
I'm sure it has more videos but they are unlisted or so
It's probably his main channel, I mean like the channel that was created with his account. And when he wanted to post videos he created another channel linked to the same account and called it 3blue1brown.
@@xXDarQXx yup this is probably his "personal" channel
I'm very glad to hear a discussion of computational fluency 🙏
I was very happy to see you got Dr. Kontorovich to sit down for a chat. I enjoy listening to him.
I just realised that Alex is constantly smiling through the whole interview, this plus the fascinating discussions : no wonder I was so enthusiastic and happy watching this podcast ! Thank you for this :)
indeed , i just want to spam a hundred thank yous in the comment section, lol.
Thank you, I like this a lot. Looking forward to future episodes. For the ultimate math interview podcast crossover you could have Brady on ;)
40:16 YESSSS HE’S DOING THE UNSOLVABILITY OF THE QUINTIC!!! I’ve wanted to understand that for so long. I can’t wait for that video!
There is a theorem called "Abel-Ruffini" theorem, which explains it.
@@playerscience well yeah, but the problem is I don’t yet have the background to understand the proof of that theorem. A 3blue1brown video would at least give an intuitive explanation.
i think that that particular topic was to be given at a talk at the 2021 IMO (International Math Olympiad), and not meant for a specific video. (sorry to burst your bubble)
@@spegee5332 :o dang. Is there a video of that talk somewhere?
The classic proof of the Abel-Ruffini theorem uses pages and pages of algebra and is a bit of a tedious slog. The modern proofs, using Galois theory, are much nicer and much more general, but they are also much less accessible. For most people, it takes at least two semesters of intro abstract algebra to work up to a full understanding of that proof. I don't think I've ever seen an accessible presentation of that proof, and I'm skeptical whether it's possible.
Please keep going with this podcast. It's hard to find good podcasts in technical and scientific areas where the conversations are still accessible and entertaining.
Prof Alex Kontorovich has a channel too where he has lectures on complex analysis, number theory and more. 5 min in the complex analysis lectures, and i was like , wow. He explains why of things , not like just the math but also math history and good stories.
My most profound thanks to Grant and Alex for this informative talk. As an aspiring professor, it was great to see that I share a lot of opinions with Alex.
Thank you for this excellent podcast promoting maths as an exciting activity.
I love your channel! Regards from Argentina 🇦🇷 .
Congrats on the Copa America
Great show! Ive wanted a nice podcast about maths for so long :)
Hope you do lots of these!
Thanks Grant for these podcasts.. They are really helpful for PhD student like me..Please Keep on making these kind of videos..
Great first pod, Grant!
One small suggestion: it might be useful to put time stamp of all important points/question in the description. As a viewer, sometimes it’s useful to directly jump to interesting discussion rather than listening to whole thing.
An engineering student now. My parents are immigrants (who moved to the UK) and we were quite poor and back in their home country of origins they weren't really educated especially after the devastating impacts of war and famine that held back our people for many years and so Mathematics, Science, and Engineering isn't something I found a love for or really understood until the last year of middle school where I started to teach myself Mathematics and Science in an already muddled, rubbish curriculum, that didn't teach help children find what they love and help them understand it, but just taught children for the sake of passing the exam. So, teaching myself and understanding the beauty was the catalyst for everything up to now.
I also quite envied children who did have parents and role models that helped them understand the importance of knowledge, learning, and education (especially if it was Maths and Science) but at the same time I am really grateful for my parents for bringing me up and putting food on the table and always caring for me.
Only thing one can do is move forward and keep striving for the ability to see the beauty in things!
Inspirational story dude ! Glad you found the passion for Math.
Woooooooo Grant podcast
So excited, nice job on setting this up!
Awesome guest! So positive and expressive!
Amazing! Looking forward to this
Wow finally a math podcast!
You could make a channel with cuts of your podcast, will be good cause i can see the clips in the interval of work. Thanks a lot, from 🇧🇷
I'm so happy you started this podcast. I don't know if it is a popular opinion, but I'd rather watch the uncut material. Cheers mate c:
I love the way how Grant addresses people as "This Human".
Really great first episode! I'd love to see figures like Edward Witten and Sean Carroll on the podcast in the future!
this conversations are pure gold!
Fantastic podcast! Thanks for this.
"You need problems to excite you, and then you need the skills that we teach in school whose sole purpose is to make thinking obsolete" - and we are labelled as "intelligent" if we excel in the very skills whose purpose is to make thinking obsolete!
Asa ahe ka...waah , 😂
As someone who excels in those skills and so does well academically, this thought often gives me imposter syndrome in the sense that I feel a far worse mathematician than most the people around me at uni, despite generally doing well in exams
Nonsense. These skills are the alphabet of mathematics. Alone, they are not enough to get you good grades in class. It's that most students are so bad at math that they are struggling with the basic stuff that they can't even see the creative aspect of problem solving which is required for the best grades.
This was incredibly interesting. Thank you.
Hey Grant, very nice podcast! All the episodes so far have been stellar. I'm listening on one of the nice podcasting apps (not you Spotify, not you Apple). I'm just dropping in here to see what your guests look like Poggers
great talk! thank you!
Podcast from artist itself is reasonable thing to get ideas and learn from these wise minds. First podcast is lucid, it try to clear the narrows gap between school/college learning and actual field work. It always gets encouragement even anyone can merely used math everyday. Well, good luck for future interactions.
I got interested in math when I was very young. For some reason, I loved finding patterns and numbers and geometric shapes and puzzles and logic, and also science, especially physics and basic programming. It's kinda complicated to explain why I like numbers and patterns and doing puzzles; it's just that they're intriguing and beautiful and all... and that's what made me get hooked into math when I was younger.
My life just got better, thanks to you
I realised the awesomeness of math in the last year of high school. Before that I had very bad math teachers at school, who literally didn't teach anything, they just made students like me to just memorize the math problems and spit it out in exams.
But when I came to college, new teachers came who taught me in the right way! and then my curiosity towards math grew up.
I'm 628th subscriber.
Btw 3blue 1brown is like that channel which will open your mind in different thinking skills.
Nowadays everything has become so interesting that you can't be focused anymore 😓🙂
So true!
It can be helpful to have a make a game plan following undergraduate syllabus and choosing textbooks. Check out Math Sorcerer on RUclips.
That intro is just stunning!
one and only one word : Inspiring!
Grant. This is a great yeoman service you re performing. In hinduism, math especially infinities is considered the language of the gods. I especially lked your videos on the infinities and series in general and the intuitive thinking you tend to provoke. THANK YOU.
This is perfect!!
Timestamps with conversation topics would be great for future videos
It's always fun, exciting and a lot more adventurous to listen to someone who has played at the beach and swam in the ocean when u have just built balls of sand at the river banks n found joy in throwing them into the water!❤️❤️
I’ve been to the Mo Math Museum in NYC. I have a photo taken of me sitting on a turning chair with red and yellow lines that form an hour glass shape as you wind around.
A real pleasure. Thanks!
SO excited for this podcast finally can’t wait to see where it goes!! I love the long form math discussions so this is literally perfect
Does his last name relate to contours?
Underrated comment
"... and by kids I mean phd students" got me good! Great podcast!
I'm maths student and really loved this vid 👍
Also, assuming everyone watching is a unique person, then that means a 84% viewer-subscriber ratio, which is incredibally high for such ratio. Normally I see a 10% ratio of viewer-subscriber ratio.
some channels that spam videos have over 100% ratio
@@aphraxiaojun1145 that's a youtube bug
@@30IRUclips I mean he is a big creator already
The fallacy here is that not all subscribers watch all the videos
As a subscriber, I can assure you his subscribers have subscribed for a reason! And I’m always excited for the next episode..
These are genuinely *asset for the education system*.
And one of the things that keep me coming back to this channel is how grant is truly trying to make the world a better place.
I mean, look at him, *he has like almost everything* yet he performs more projects just for the sake of making math/education better.
Honestly speaking, he needs to be in the education ministry. And he deserves so much more. My love and prayers are for him
This is much better than Roe Jogan
Edit: I appreciate Rogan interviewing many high-level STEM guests but the conversation depth can only go so far. Would love to see many of the same interviews with Grant as host.
Not being dumb enough to invite conspiracy theorists to your show is a low bar, lol
I am curious, is Alex related in some way to the famous russian mathematician Kantorovich who worked in the field linear programming?
His models are taught in universities here in Russia.
I am very curious!
I have had this question for so long!!
isn't he Kantorovich? idk if the spelling matters that much
@@flatmodule839 Well, it might matter but the possibility is rather small I would say.
Yeah he is his son from another dimension.
There is so much interesting stuff out there but the signal to noise ratio is low in journals etc so it would be nice have a map of universalities and the top teaching resources, like a Wikipedia stack-exchange RUclips mashup.
When alex said abaut the soviet system being ahead of the American , I had the same experience when I came to america from italy so its nice too see I wasn't the only one that had it that way
I used to live in India and the math curriculum there is way more ahead and rigorous than in the US. I remember set theory and graph theory were taught in high school.
I would LOVE to learn more about Soviet mathematics, either the history of, Soviet mathematics pedagogy, etc. etc.
That was very nice!
it will be very interesting to see if complex & Fourier analysis can be codified into Lean
Thanks for the great podcast, Grant! Can you make these episodes available on Spotify as well?

Tip: it looks like your camera Auto White Balance is a bit too aggressive, you may get a better result by locking it in to a single value.
I clicked on this not thinking I would really be interested now I cant stop watching even though I should sleep right now :D
Thank you for providing an RSS feed. So many podcasts don't these days
maybe I not 40 years old yet to understand. But why do you need RSS for?
@@gaous Lmao. I just looked up how old RSS was so I could tell you I'm younger than it, but I'm older by 2 years. In any case, I'm not 40.
Why shouldn't I use RSS? For me, it is more convenient. It's open, not dictated by some big company. Why should I need to install a spyware app to listen to podcasts?
@@MarcelRobitaille Good to know that :)
kind of off topic but grant’s voice is so deep and raspy and perfect to listen to
One thing about Lean and Coq - how do you proof that there is no mistake in checker itself? Like, for example, Rust programming language were claiming that it is memory safe if you don't use "unsafe" blocks. But then, counter example appeared, without unsafe blocks but leaking memory.
Thank you :)
Hope its not too late for a podcast with Tai-Danae Bradley, perfect fit for this podcast imo
Both maintain a smile throughout the interview making em even more likeable..maybe I should smile often while i speak and hope ppl like me better😅
Re that last question: Veritasium uploaded on Collatz today - it featured Alex extensively.
yeah
What a thoughtful exchange of ideas, You are a great interviewer (reminds me of Joe Rogan curiosity and line of thinking)
Can this video be timestamped with sections like the Steven Strogatz one?
Talking about steering mathematicians to do certain things: Alan Turing and the enigma is a good example of a very good pure mathematician being forced to work on a very concrete applied problem, and producing some moderately important outcomes.
Math Podcast nice!!
I saw he video was 1.5 hrs long and I thought to myself "oof that's way too long". I was only going to watch the first 5 min to see what it was about but it was so interesting I ended up watching the whole thing
damn the examples are so beautiful in the talk
What’s the experimental math journal called, and where can I find it? I want to look at it to get a better idea about what experimental mathematics is.
Edit: it’s in the description
Can u make a video about graph theory
It's just a topic I haven't learned deeply and think it would be interesting to learn from someone like you and ur very uniquely way of teaching.
I know it's not the chanel u do stuff like that but sense it's a new chanel I think I have more chances of u seeing this comment
The problem with cell towers at around the 50:00 minute mark reminded me of an engineering video I watched about culverts; there are many ingenious designs to improve flow rate, but often the best and cheapest solution is just to make a slightly bigger culvert.
Leaving the comment here for the very first video.

The satisfaction LOL 😂
Respect +++++
A video podcast and yet no footage of Grant on the square wheeled bike at MoMath?
About an hour in Kontorovich mentions two people who wrote a book where on the five hundredth-about page they prove the theorem (1+1)=2 and attributes one of the authors as Tarski, I believe he's talking about Principia Mathematica by Whitehead and Russell. For completeness I wanted to note this in the comments
And ofc, "by kids I mean phd students" is a gold line
I find the discussion on pushing mathematicians towards "important" problems to be very fascinating. I often think about what kind of society we could have if extremely strong problem solvers were not economically incentivized to get people to scroll a newsfeed 0.001% longer, or eke out a 0.001% stronger advantage in the stock market. Of course if that were the case, who gets to be the arbiter of important problems? The NSF?
Are these on Apple podcasts yet? I couldn’t find it on there.
can't believe I spent one hour watching this (watching it at 1.5x speed). don't regret it a bit! love you guys (well, i don't mean it that way :P, old guy here, working in a math-related field, graduated in a former communist country too). edit: "the second second tower" - the drama of my life... people are hard to change. Kudos!
