The "I don't know" aspect can have humorous connotations: There is the story of a famous British physicist giving a lecture on some new theoretical concept. He got to a part on his scribbles on the chalkboard going from one set of equations to another and said, "It is intuitively obvious that this leads to that," and was just going to swap over when he looked at the two formulae and said to himself, out loud, "Is it intuitively obvious?" He shook his head and exited the room, leaving his audience wondering what was going on. Some time later, he triumphantly marches back into the room, displays a thick sheet of paper with his scribbles all over it, and says, "Yes, it IS intuitively obvious!" and continues the lecture...

[@nanigopalsaha2408]

Nice, but there are a few problems. A) The man was not a British physicist, but the mathematician Godfrey Harold Hardy. B) There was no new theory, he was just giving a lecture. C) He did not say 'intuitively obvious' but rather just 'obvious'.

@Nathan Okun: Reminds me of a side story about physicist Ludwig Boltzmann, related by sci-fi writer Alfred Bester in his short story, _The Men Who Murdered Mohammed,_ which centered on a (more modern) absent-minded physics professor who invents a time machine. According to the side story about Prof. Boltzmann, when he gave his lectures, he would rapidly scribble the math on the board, going from one proposition to the next, each time skipping several steps he considered obvious. His students suffered this in silence for a few sessions; but then finally a group of them approached him after class, imploring him to include more of the steps in his derivations, which he consented to do. So the very next lecture, he began breezing through yet another rapid-fire series of equations, saying, "This follows as easily as 2+2=4." Then, remembering his promise, he stopped and wrote, "2+2=4" and continued scribbling in rapid-fire mode... Fred PS. Any relation to Milton Okun, of 60's folk recording production fame (incl. Peter Paul & Mary)?

Hearing about Matt's first experiences and interests with math brings me some fond memories from my own childhood. If it weren't for my ma and my grandpa(Ma being a puzzle junkie, and grandpa a chess addict), I think I wouldn't have cultivated such interest in mathematics. Matt is a truly amazing human being for showing this brighter, goofier side of mathematics, as well as the depth and relationship it has with all manners of human life and entertainment. This sense of wonder and interest is absolutely contagious, and a huge service to society and to the science and art of mathematics. If only everyone had this enthusiasm, this giant off-the-rails puzzle game would be way more appreciated by youth and adults alike.

[@TheDesertRat31]

@Gareth Tucker it's more complicated than some half conceived admonishment. Schooling has to be done in a group setting, school systems buy a curriculum program and sometimes that's more scripted than you realize, public school funding is hit or miss at best, teachers do the best they can, which is much more than you realize, and they're not mathematicians themselves.

[@TheDesertRat31]

@Gareth Tucker no, I suppose we aren't from the same country. In the US, public school teachers get the short end of the stick and are the first to be criticized for supposed problems and held to account for outcomes that stem from family issues in students' homes that they have zero control over. They are forced to try and work miracles to make up for the failures of school boards, upper administration, and shoddy parenting. And politicians like to be critical and make speeches when it's convenient for them to try and score points with voters. My wife is an elementary school teacher. It's a touchy subject with me.

At university we had a running joke that when an experiment did not work ... like at all, that we will publish it in the "Journal of failed Experiments". And to be honest, that is something that should really be a thing. I can only imagine how many ressources were put into trying certain things because nobody knew that others have tried them and failed, and thus never published their findings. Of course it does not mean that some of these things are impossible to work, new insights or developments might bypass aspects that make them not work, maybe there were mistakes that nobody noticed etc, but just knowing what people have tried, even if it didn't work is still very important knowledge.

On the question of how to get people to not be afraid of maths, I'm not a school teacher but I've had a lot of success with making games that teach the practice of an equation. The question is "Why do I want to know this?" The answer should be either it's useful or it's fun. Having a game that is fun, not a boring memorization exercise with a game slapped over it, is a great way of getting people interested. I think that's the core of the idea of using magic tricks to teach maths. So maths teachers should be game designers.

[@Lemu_with_a_shirt]

The maths teacher point is really important I think. I always liked maths, but then I got maths classes in school, a teacher who didn't want to be there, a constant rush, not enough books for everyone, not enough time to always check your work before continuing to the next problems, and no attention paid to the process, only the results... I needed a long break from maths after that, because it just became stressful and I couldn't find joy in it anymore. I barely remember anything I learned there, because nothing made sense. The past few years I've been reigniting my interest with the help of things like KZbin, it's fun again and I can retain the knowledge because the logic it revealed.

the part about math as a recreational activity describes my childhood perfectly! i remember talking math at the dinner table growing up. i even did test runs on the math quizzes my mom made for her students. my dad has a masters of engineering degree and my mom has a masters of science degree and their attitude towards math played a huge role in how i came to like it too! and even if i am currently in the humanities field i still love puzzles and math to be a part of my recreational activities! i will definitely buy this book and read it, before handing it over to my parents. i think we will all enjoy it!

I've noticed over the years that both Matt and Adam are extremely smart, (not a novel observation). However, Adam is "Right Brained" (intutative, thoughtful, and subjective) while his chosen profession since Mythbusters is one normally associated with "Left" brained (logical, analytical, and objective). He doesn't struggle with this, he is just that brilliant. This is such an unusual combination, though, where historically many others with such combinations sometimes are "fakes" or inventors of cooky and acentric ideas which never take off and yet they never let go. Matt is the exact opposite and yet also still not fake. They both are in the same business. This is such an interesting interview given such similarities and yet such strong contrasts.

Long story short, I decided to see if I could find a method of generating the sequences of numbers in the diagonals of Pascal's Triangle. Not being a mathematician, I didn't really expect to succeed, but I gave it a go - and I actually succeeded! Then a few weeks ago I found another, completely different method! I knew how to build the Triangle row by row using addition, but I wanted to see if I could find a way to build it diagonal by diagonal. It was a lot of fun! 🤓

One of the best teaching methods i was ever part of consisted of three parts. They were called large group, small group, and labs. Not all classes had labs. But anyway, large group was the entire student body for a particular class sitting in a lecture room, and you were lectured at and took notes. No questions allowed usually. So large group could be over 100 students at a shot. Then, in small group, you'd sit down around a table, and 10-12 students and 1 teacher would discuss and elaborate on the large group lecture. So you got the big info dump in large group, a chance to really dig into the info in small group. It was the best of both worlds. And labs were just that, if you were taking a class that had any kind of lab work, that's when you did your labs.

Mine was far simpler, I was around 8 and trying to work out the hypotenuse of a rectangular prism by working out the hypotenuse of the one side and then repeating with the hypotenuse and the 3rd axis. Suddenly on my page after simplifying it a bit was x^2 + y^2 + x^2 = h^2. Now obviously, deriving a 3D Pythagorean theorem from the 2D version is hardly genius level work, but it was the first time that I has some kind of aha moment into "what math was really about". This was in the 80's and I was teaching myself to program rudimentary games in BASIC, and until that point all of my self taught trig and stuff were purely tools to work out cartesian stuff for the games.

I had a ridiculously hard time with math until my junior year of highschool, where i actually had a math instructor who figured out that i needed to know WHY things worked, rather than just memorizing rules. Then, when i got to college, i had to take "Technical Math" which was the name of the course, and it started (at the college level, mind you), with a number line. But it made the rules of math make sense, instead of a bunch of rote rules. I think anybody could be good at math if they are taught math correctly. As in not learning a rule that doesn't make sense, and instead give you a set of rules that are consistent. And because they are consistent, you learn it once and use it forever after.

I am a lapsed computer science teacher and I have always admitted when I don’t know something. It does shock students though as they expect me to know everything. Like Matt said there are different levels of not knowing. With coding there is often a ‘what the hell....’ level where it (some code or a computer) does something unusual, often caused by a limit placed on the network due to it being in a school. I created an ISS tracker in Python that worked absolutely perfectly at home but refused point blank to run in the school. In the end it took my boss, the school IT tech and a visiting IT professional four hours to fix. I apologized profusely but was told it was the most fun they had had in ages. They had to write code that tricked the school firewall to let it create a temporary cache, and then only query the cache and not try to go back to the online data service. It meant the location of the ISS was only really correct the very first time the code was run, but we didn’t tell the kids that and everyone was happy. Fun times.

This thing about openness regarding mistakes .... I have an interesting account.. A little back ground ... My grandpa, my dad and my stepfather were all civil engineers and my mom was a delineator. This is no trivial thing in a child's life. Things like building a sugar cube mission, a log cabin, or an Indian wigwam (all of which were common projects for elementary students of my generation) became a major lesson in plum lines, angles, stress load, and a number of other things that were beyond most students in elementary school. Children in my family seldom had coloring books, we instead got rolls of old plains for houses and maps and such like that. That perhaps contributed to my 1st grade teacher's use of a the floor plan I drew when asked to draw a house as evidence that I was a bit "slow". Well, perhaps my floor plan was a bit "slow". After all she didn't have a a straight edge for me to use so it was all free hand. Then there was the bathroom which was the largest room in the house having 3 sinks, 2 toilets and 2 bathtubs. (I was 1 of 7 children and I though that was an excellent remedy to bathroom time congestion). I distinctively remember my dad's calm, patient, teaching tone as he explained to my teacher some very outstanding (for a 1st grade) features of my floor plan including the correct use of symbols for windows, doors and wall thinkness. This was the beginning of my concept that all people didn't know all things like my dad did (it wasn't until my teenage years that I momentarily though he was a blooming perfectist idiot). My dad when we got home from school using the same patient, calm, teaching voice to help me improve my floor plan. This may have been when I started to develop the idea that it was a very good idea that my dad and mom from time to time kept us out of school (more often than the school likee) so we could go see interesting projects their agency was working on.. So to the account about not revealing mistakes. One day the family was on a car trip and we children started asking about why same curves were banked more than others and why the straight road wasn't banked. We learned about cloverleaf and diamond acceleration / deceleration zones, the out ward force on an object making a turn, and my eldest sibling who was learning to drive knew that it felt more comfortable when making a curve at the correct speed. In the course of the conversation my dad told about an engineer who for thought that banking the curves the wrong way on a 2 lane country highway through the mountains would be a good way to keep people from speeding. My dad had told us believe it or not, not only was the plan conceived, and designed, it was approved and constructed. All of us children wanted to go see this road the next time we took a day trip. My dad told us he wouldn't tell us where it was because it was a secret but that most of us had been on the road. He told us that if we could individually identify the road giving good reasons for oir choice we could be in on the secret. We of course wanted to know why it was a secret. My dad explained that although the speed had been reduced in that area due to the curves and road conditions to make the road safe there would still be people that would try to sue the agency that designed and built the road if they had an accident on it. He explained that of course such people would have no case but it could still cost the agency millions of dollars to prove the persons attempting to sue had no case. I think this was the beginning of my thoughts about how dangerous it is to attempt to lay blame at all cost for things that happen without any malice or neglect.

What a great interview! Adam Savage’s Tested is one of my new favorite channels!!!

[@rogermiller2159]

When my wife and I were raising our son we had alternate schedules that enabled us to give full time with our son. My wife came home one day and caught me playing with a Thomas The Tank Engine train track. I told her I was trying to make a track using every piece of track. She was hooked in. We spent a week or so to the challenge. Then we added in to complete it in smaller area. It was great fun. By the way, my wife was raised on logic puzzles. Daddy would come home from a trip and give her a treat. I was raised on sugar and TV.

[@wiscadams]

I love it when the people I follow cross paths. I really hope Matt appears on the podcast or collaborations with math geeks starts to become a more regular thing.

Brady's First Law - "Is there an infinite, or finite number of them?" is valid in any Numberphile video.

[@JigmeDatse]

Collet's conjecture (spelling from subtitles) I think the rules are: If n is odd multiply by 3 and add on (n(n+1)=n*3+1) if it's even divide by two (n(n+1)=n/2) I think my notation is terrible.

It's a joy that Winston is still holding the list of attendees.

[@engineer-of-souls]

35:01 I'm bit disappointed with Matt for not making a factorial joke about the band Snap!

[@Stelus42]

"If you learn this skill now, you can annoy your friends and family" one of Matts best lines, which is saying a lot.

[@enbyennui]

Hearing Matt say "math" feels so wrong

[@LeoStaley]

It makes me irrationally angry

[@mrsnowman8865]

sounds ok to me

[@fanq_]

I was just about to say that... it just feels off... but he's probably trying to not make the mostly american audience go like "maths"?

[@Simon-ui6db]

Yet Adam did say maths so the equilibrium is reset.

[@chartle1]

yea to create the US from the UK version was what a macro //FIND "Maths" REPLACE WITH "Math". :)

[@tlecoyotl]

I had to get so close to my screen because I just couldn't believe it. It is really my favorite square theorist with Adam Savage. The world just got a little better.

[@kylejacobs1247]

1) how often does Adam find the ruler tattoo useful 2) how often does he check it's accuracy

[@Yupppi]

Great video! What could you enjoy more than two enthusiastic people talking about what they like. I can totally see why in engineering you can't share the mistakes even if you wanted to. Usually it doesn't matter if you learned, people remember your company as the ones who messed up and try to hire somebody who doesn't have that title on their forehead. I guess it's the feedback loop all the way from the beginning saying you don't want to make mistakes, you want to be spotless. Even when they quote edison saying he found 999 ways to not succeed to come to the answer. I also remember those teachers, or substitute teachers, who stopped to figure out something after they were asked and it felt really engaging. We were suddenly part of the team, all of us, and it became so much easier to ask questions in the future too. You discovered they don't know everything and that they too figure things out through hard work. A lot of the uni teachers luckily go through that when they haven't prepared something and you get the feeling that you can figure it out yourself as well, through some logical steps.

[@MrSJPowell]

This was delightful. Thank you both.

[@panda4247]

5:34 the famous Parker-Collatz conjecture odd x ==> x*2 even x ==> x/3 or something it started with such confidence :D

[@Mr.Feckless]

These guys need a regular show together these are some of the best pieces of content either has.

[@johnydl]

Whooo thanks for answering that, I now want a "MathBusters" Calculate pi in the most esoteric ways collab XD

[@PassionPopsicle]

I second this!

[@Ramzuiv]

The Parker-Collatz conjecture: "If it's even, you divide by three" 5 ... 10 ... 3.33 Wait... is 3.33 even or odd?

[@mattmorgan2525]

The question is not whether it is even or odd, just whether it is even or not even.

[@dimitri877]

I love both your channels, Adam's, and also Matt's. I still learn so much from the both of you. This video reminded me of a discussion I had with a couple of friends about the following: What is 6/2(1+2) ? The way I learned is that you first have to get rid of the brackets, making it 6/2(3). Still brackets there, so 2 times 3 equals 6, no more brackets, boom problem solved. 6/6 ((2 times 3 before dividing by 6)), which would equal 1. But the interwebs exploded on this equation stating it should be 9 ((6 divided by 2, which equals 3, times 3 which would equal 9)). ..so my question is: 9 or 1????? ..I was and still am so bad at maths, despite the fact I understand how a Rubik's cube works and how a Rhombic Dodecahedron relates to Hard Spheres. But I just can't wrap my mind around maths when one source says X, and and another source says Y.. ..please help me understand this conundrum..

[@martijndekok]

I was looking forward to this video. What a great way to start a new series. Two smart and funny guys who inspire learning with their infectious enthusiasm.

[@SomeNerdOutThere]

I still remember my math epiphany as a teenager. I grew up programming so already used math for that frequently, but my mind was blown when I learned about matrix transformations. I ran to the computer lab in the next period and whipped out a 3d rotating wireframe cube animation.

[@MrKyltpzyxm]

I can relate to Adam's story about getting emotional watching Numberphile. I will sometimes tell people about some exciting fun new math thing I've learned only to be met with a blank stare. As if to say, "You've just used the words 'math' and 'exciting' in the same sentence. Surely I've misheard you somehow."

[@mintygrey]

Absolutely ADORE this video. I came across this by accident, while taking a break from writing a very long and tedious document, and I actually feel inspired again.

[@Dagobah359]

20:11 My dad is 'famously' bad at math. He's proud of the story that he was sick and missed 2 weeks of school and so never understood algebra. Me, I went on to be the first person in my family to go to college and I got a PhD in math. My origin story: I hate arithmetic and thought math was horrible. (In hindsight, I wasn't challenged and my ADHD brain was bored out of my skull being forced to do 100 arithmetic problems per worksheet every day, when I had gotten how it worked when the teacher showed the algorithm on the board the first day.) It was in pre-algebra when they showed that you could set up an equation and solve it to find the answer to something practical and I saw how universally applicable and powerful that was when I saw how beautiful math is.

[@bonolio]

On the question of how to make maths more enjoyable. It turns out that I am completely rubbish at learning things by rote. I just don't memorise facts well and then retrieve them at will. What I am really good at, is learning something and then working out why it works like that, and then being able to reconstruct the rote learning from the underlying principles. This meant that early maths was terrible for me, because it as lots of memorisation and remembering what formula to use it what situation. At some point I needed to work out the hypotenuse\diagonal of a cube and after starting with the basic pythagoras, I quickly worked out that d^2=x^2+y^2+x^2. Now this may not seem like a great discovery but I was only 11 at the time, and this gave me the epiphany that maths wasn't something that I just needed to memorise, it was something that I could explore and remix for my own needs and that by understanding the principals I could creatively explore the world of numbers and what they represent. Maths needs more creativity and exploration over rote memorisation and regurgitation.

[@jamesbuckingham9072]

I remember that puzzle Adam mentioned around minute 24. Probably around the same age. Fiddled with it just to see how the pegs moved. "Okay, there's a pattern here." Having recently discovered the joy of number systems, I thought "this feels a lot like counting in binary." At which point I recognized it as just a more complicated version of the Towers of Hanoi puzzle. So it didn't take long to solve, but the enjoyment I had working it out stays with me decades later.

[@hholguin89]

I love what Matt says about enjoying the challenge. Because that applies to everything. Me, for example, I play a lot of video. People might assume that I'm good at them, but I just enjoy the challenge. It's just a great feeling when you conquered a tough problem as opposed to conquering an easy one

[@scotthodgins7975]

The most interesting book about math that I have ever read was called (I think) "The Rising Fastball" (that also may have been a chapter in the book). I got the book for Christmas about 40 years ago, and it described how we do math all the time without ever realizing it. My favorite 'tidbit of knowledge' in the book is this: A third baseman throwing to the first baseman is actually aiming at a point roughly 16' above his head. The whole book is filled with neat nuggets of information like that.

[@joemedley195]

I liked where he said that many in math like that it’s a challenge. I work in tech. I discussed with a coworker once that many of us in software don’t mind and often even enjoy being temporarily confused.

[@digitig]

Joe Medley It's interesting that people don't realise that, yet take it as a given in sport, which of course plenty of people do recreationally.

[@MattThaDJ]

I have never been into maths and am terrible at it but I had a smile the whole video and now I want to learn more. Thank you for the wonderful chat.

[@Baiswith]

I remember spending a couple of weeks setting up formula in an excel spreadsheet to solve sudoku squares - that was fun :)

[@Egilhelmson]

I took an entire sailing season, only working on weekends. It is amazing how difficult a “simple” problem can get.

[@parrottm76262]

I just loved this discussion. I'm a self confessed math nerd, and anything that encourages others to expand their mind set is a winner in my 'book'.

[@davidsharp9166]

Would love to see a tour of this library, with Adam explaining why some books are in those places and where he got them from? Anyone agree.

[@stargazer7644]

I was trying hard to read the titles.

[@mattcy6591]

I like how the pages count down so you know your progress towards the end.

[@nawdawg4300]

I love Parker and Savage for completely different reasons. This is an AWESOME duo.

[@TrimutiusToo]

I am so greatful to my dad who made me calculate minimum required number of moves in tower of hanoi (with 8 discs) when i was 6. He still says he was surprised hen i came up and said 255. I actually invented recursion for myself back then. So when i had to learn recursion in school later on it was natural for me.

[@christopherbiomass7155]

24:20 I still have mine from the early 80's. I find it relaxing to do with my eyes closed. (not a brag. it's very easy once you know the progression) [edit: changed: mid 70's to early 80's]

[@TheGoodestBrandon]

How is this JUST now hitting my feed? I watch Adam and Matt regularly

[@joebrinson5040]

Thanks for a great interview with Matt Parker. The interaction between Matt and Adam is very appealing because of their common interest in maths.

[@Gomisan]

Fantastic interview. I love Matt's videos and Numberphile and my wife thinks I'm a bit odd for watching math vids on KZbin. So an interview with my favourite maker just makes me feel like I'm in a room with friends! I've ordered teh book and am looking forward to a great read!

I'm one of the ones scanning the background for insight into Adam. As a LARPer and owner of a number of foam swords, it breaks my heard to see the Excalibur replica resting on its tip!

[@johnglielmi6428]

Thank you both for this wonderful video. Adam may I say I am a huge Mythbusters fan. Engineering was such a GIANT factor in it, therefore the MATH was essential to the proving the myths. And Matt thank you for letting kids know that math is a beautiful thing, and encouraging them to except failure and continue. I've always been a person that loved a mental challenge, and I had teachers that would always encourage me to continue. If only all teachers would be more involved with their students learning. I did have some teachers that just barely cared about if the students even were learning anything. Teachers need to find ways to get students more engaged in learning. And you guys do this so well. Thank you, thank you, thank you!!!

[@ckannan90]

Much deserved Brady Haran praise in this video. Brady is always the hidden person behind the camera that it’s easy to forget that the videos wouldn’t be anywhere near as good without him applying his mind to it with such sharpness.

[@tasmanianerd2558]

Another mathematician to read - Adam Spencer from Australia. Informative and funny!

[@djsyntic]

So in regard to getting young people enthusiastic about math, I think it's important to consider those things that kill enthusiasm for it. In general, I love math but growing up many times I would hear people complain about story problems. I myself would sometimes complain about them. But that doesn't mean I think they should just all go away. What is it about story problems that bothered people so much. While I can't speak for everyone, I think one of the things that bothered me so much about them was that many of them were just excuses to get you to do a certain type of equation you studied that week, while throwing in numbers that didn't actually reflect reality in any sort of way. It takes time to learn to do math well, but we learn much more quickly to instinctively know if something is right or wrong. So when we do one of these word problems that sets up a situation that just doesn't mesh with what is real we get the initial ping of "This is confusing". But then you struggle through the problem and reach an answer and you are looking at the answer and have no clue if that is right or wrong because your instincts keep trying to apply reality to this problem that had absolutely nothing to do with it in the first place. Then as you grow you better understand that the word problems you are given don't match up with reality so you start asking the question, "When am I ever going to use this in the real world? The real world doesn't act like those word problems." and teachers often just don't have the answer to that question. So my guess on how to enthuse people with math? Try to relate it to the real world as much as you can. If you want a word problem that uses some concept that you studied that week, make sure the word problem isn't just shoehorning in that equation even though it doesn't actually belong there.

[@ragnkja]

DJ Syntic That’s a good point. If used right, word problems could be a great way to build intuition, but instead they’re pretty much exclusively used to teach how to translate from words to equations.

[@MrChief101]

Gents, nice inauguration of the re-purposed Talking Room. What I particularly like is... you both have taken your shoes off. Very nice and comfy. Good show. Good book.

[@Janos0206]

What an amazing crossover!

[@Sam_on_YouTube]

I remember getting a tangoes style puzzle with a cheackerboard pattern from the museum when I was a kid. It had 100 patterns. There was one I just could not solve. Then I counted the white and black squares and proved definitively that it was impossible. I also got the closest solution possible and showed that if my solution existed, there was no way a correct solution could also exist. I wrote a letter to the company with my findings. Never got a response, but it wasn't long after that that I started working on the Rubiks Cube, which I figured out myself without being taught. Took over a decade on and off.

[@tannerbass7146]
