As someone who recently got their BSc in Math, I loved every second of this video. Professor Moon Duchin is so passionate, I envy the students who got her as their professor. I think the main FAQ I hear about math is “When will I need this in my life?” The simple answer to the majority of it is that you do not, but that rather it’s the opportunity to think logically, problem solve, and critically think and examine that you do need in your everyday life.

When she talked about how ppl in math don't/can't explain their subject matter enough to the public, I felt it in my soul. When I was young, I really liked math, I felt like I understood it and could be proud of it, I even wanted to be a mathematician, it was a time when explanations made sense and weren't a handful of unintelligible(to me) jargon that had me stopping every 5 minutes asking for a more precise description. As that kept happening, repeatedly, where I constantly asked my teachers and felt like I was inconveniencing everybody, I eventually stopped asking for an explanation, stopped feeling curiosity, and steadily lost my love for math. It felt like the silent breakup couples have, you don't say it upfront, but you know there's a distance, and the boat to cross it had sunk deep down.

One of the most incredible Q & A I have ever watched on KZbin. I just love this!

[@nivolord]

What I like about this video, is that the professor doesn't answer the questions directly, but rather addresses the reason for the question, which ends up being a lot more informative. For instance, the "times before plus question" could be easily answered by saying that it doesn't matter, since whatever choice you make you can still use brackets to express anything you want. But that is not a helpful answer, so the explanation given in the video talking about the "rules of mathematics" is much more illuminating. Like the comparison with chess too.

There's a big difference in failing to explain a groundbreaking mathematical proof to fellow mathematicians and failing to explain it to public.

After so many years, I'm convinced the problem of mathematics being considered hard/boring isn't mathematics itself, but how THEY TEACH them. I suffered with maths throughout elementary and middle school. It was a nightmare. But then a wonderful teacher at high school, who didn't mind bringing a huge case (literally, she carried it everyday like it was her sword and shield) full of all sorts of stuff, made my generation fell in love with maths. Everything was "going back to basics" as part of the last segment of her class: she then opened her _magic case_ and took out bottle caps, cords, pieces of wood, marbles, sticks, chains, plastic cups, dominoes, little dolls, action figures, old coins. Anything served. She then said "if you can _manipulate_ maths, and I mean touch them, see them, even smell them... it'll be easier. Trust me". We were a bit reluctant and mistrustful the first week. I confess I even thought what kind of drugs did she take on a regular basis. But oh man, I was wrong. Not only it was fun and relaxing to start doing math problems with all that stuff, but in a very prodigious way... she fixed the awful void I was been carrying all my life, regarding maths. I'm being honest: I finally understood fractions (in its formal meaning) until I was 16. How she made it? We formed a percussionist enssemble (we were horrible, but it was fun) with her as our conductor, using our hands, sticks and cups as musical instruments. We then analyzed time signatures and the magic was WE WERE ABLE TO HEAR THE FRACTIONS AND WE COULD PLAY WITH THEM! I'll never forget the class reaction. It was that beautiful moment of mind clearness. And then... you smile. She was the best teacher I ever had. Always full of energy, enthusiasm, new ideas and good humor. She loved her profession and she made us love maths. She passed away in 2015. I miss her so much. I bet she's still teaching maths in heaven. Of course, with the aid of her huge magic case. Oh boy. A big thanks to all math teachers who are always in the pursuit of new ways of teaching and also think about their student needs.

She’s so cool and passionate about what she does! I love how she’s so easy to understand in her explanations :)

Do you know that what is the defference between mathematician and. Physicist , Physicist do lots of mathematics but they only see it's application but mathematician are defferent they care less about application and more about beauty because they are searching for truth.

Yeah I could’ve told you Moon was a mathematician immediately without ever hearing a word of math in this video. The vibes are so mathematician-y. Also apparently my analysis professor, Alex Eskin, was Moon’s doctoral advisor, which is neat. Facts that everyone in math loves chalkboards and hagoromo

Props to the mathematician that gives interesting and insightful answers to many abysmal questions. Props to those who formulate interesting questions too!

[@kitkatkatsuki8629]

such a good explanation of everything. i think, for all subjects but for maths in particular, its so important to have someone who is able to explain things at a level others will understand. maths teachers are probably some of the 'smartest' people in the world and i think its sometimes hard for them to remember that not everyone is as good at it as they are, and so can explain things in a way that maybe they'd understand but not for students. definitely a very important and impressive skill, thank you moon!

[@PincessSakura9]

I love her! I honestly dont even like maths so idk why i clicked onto this video, but i actually enjoyed listening to her. She is so engaging and explains things simple enough that i can sort of understand most things she's saying. Great job wired!

[@Kieranh778]

One aspect that would have greatly helped me, with learning Math, as a kid; if somebody would have given it context. We learned it 'because subject / we do'. Understanding that it is essentially an agreed language, for solving problems would have given it a lot more sense, to me. Like many languages, there are often many ways to say the same thing.

I loved the way she answered. I have forwarded to my students and others who keep asking me why to learn math why to learn physics and etc.

[@havenl2612]

I have a question for Dr. Moon Duchin : is maths artificial or natural ? Or to be more specific, does maths existe only in the minds of human race or does it existe already, and mathematicians are only trying to discover it, like physicists trying to learn about the universe?

[@antoniousai1989]

There's no answer. It's one of the most discussed points in the philosophy of mathematics

[@mostlyokay]

No her, obviously, but here's my take: math simply describes relationships between things, and so is natural. That is, nature operates according to some rules, and we developed a set of symbols and rules to describe these rules. It really depends on what you mean by artificial. Is it the same as "man-made"? Because if so, the answer is even more resounding - math isn't man-made; many animals are capable of counting, for example, and the brain consists of networks of neurons that are continuously performing mathematical operations in order to process the signals it gets form the outside world.

[@Eukleides89]

I took linear algebra recently and you really don’t get why seemingly useless things like imaginary numbers are incredibly important until you have to think about matrices. Wish there was a more intuitive way to express these concepts to kids, but math really is very abstract. Also: a little sad that she didn’t choose Euler for the sexiest equation, but that’s alright. Minsky looks very cool.

I’ve personally had some trauma with math and I never liked it at all but I think this video has helped me. I will often times find myself becoming anxious at the mere thought of math. Sometimes it would get so bad that I would start to cry. For once I finally didn’t feel to nervous about math. I don’t know what it was but I wasn’t as anxious and I actually thought of math as something intriguing rather than something scary. All this to say, I’m glad this video exists.

[@TheBruceKeller]

I saw a youtube about Fulltouch chalk, by Hagoromo Stationery in Nagoya, Japan. Funny to see her mentioning it (well probably). The factor was going to shut down and in 2015 mathematicians starting hoarding it. Shin Hyeong-seok, a teacher in Korea, then took over manufacturing it and basically saved the minds of lots of math people.
