"I hear and I forget. I see and I remember. I do and I understand."

--Confucius

[Paulo_Dirac]

"You remember about 90% of what you teach" that's why i talk to myself so much, my wife wouldn't understand

[IanLundholm]

As a 3rd year math professor, I totally agree that teaching is a great way to learn math and that working problems is the most reliable way to discern your own level of understanding. Thanks Grant and Lex!

[lipingfeng]

studying the history of math can also lead a student to get a sense of where all the math problems came from, how human beings got their mind wrapped around a particular type of math problem rather than something else.

[notarabbit]

why is Grant being interrogated by an FBI agent about this?

- Solve more problems to enhance learning at [0:31].

- Seek well-curated problem lists from textbooks or resources at [0:43].

- Preview end-of-chapter questions before reading the chapter at [0:51].

- Don't move on until you've worked through chapter exercises at [1:07].

- Use resources like Khan Academy for a structured problem set at [1:32].

- Learn programming to discover mathematical applications at [1:47].

- Teach or explain concepts to others to solidify understanding at [2:55].

All of this rings true for me. I'm a 40 something programmer but I really want to be an astronomer. I'm teaching myself undergraduate level math and physics (and astronomy too). I buy text books and I read the chapters and to every problem at the end of each chapter. I buy those "3000 worked problems in physics" books and to the problems. I have a daily ritual of working problems. I can't overstate how effective that has been at helping me get better at mechanics or calc or whatever. I also occasionally give presentations to a science group I'm a part of and that whole teaching bit... I very much agree. I do the presentations because I learn SO much in the preparation. I've thought about creating videos on subjects, even if I don't every publish them, because of the focus it brings. It's the whole Feynman technique. If you can't explain something simply, you probably don't understand it well enough. Prepping to teach something also exposes all of the gaps in your understanding. Great clip. It's all really good advice.

[snghnishant]

I'm one of the guy who turned to Maths because of programming.

[altuber_athlete]

Dude every sentence Grant says has value. I love it.

[KKkaptan]

I agree that teaching is the best way of learning. In a way, when you are writing or teaching something in your own words, I see it as if you are dismantling and breaking down the subject into small units and then rewording, transforming and building them up again into your own work such that it is embodied by your thought process which is uniquely natural to you. This then becomes largely unforgettable, like you don't forget how you tell your stories but may find it difficult to tell a story as somebody else says it.

[jacktrainer]

Stewart's Calculus was a fantastic text because you can buy an answer key with FULLY worked solutions and find out exactly what you did right and where you went wrong.

[velcro-is-a-rip-off]

Glad to have found you, particularly now. Hey, thanks.

[k-theory]

I fully believe the remember %90 of what you teach. That's part of the reason I started making mathematics videos myself, to improve my own understanding of certain subjects.

[jamesjenkins]

I can confirm... got more interested in math after learning to program. Trig suddenly had applications if you want to move your little 2D tank in an arbitrary angle that's not just along one of the 2 axes.

[dohyunio]

Teaching is 100% the best form of learning, also one of the final steps. It forces you to find the gaps in your knowledge and consolidate what you know in digestible way

[chrits]

Programming absolutely helped me get into math and see it from a different perspective. Also using Desmos to graph different functions and shifting and moving modifying the values helped as well.

[beenay]

I did math exercises in text books through kindergarten to masters in engineering. Did not understood much. Did not remember much. Understanding and visualizing what really you are doing is very important.

[coledean]

Grant’s voice literally cures my depression

[CyborgCoder]

I'm yet another example of someone that learned to love math later in life as a programmer motivated by solving programming problems. I was always pretty good at math, but never really enjoyed it. But the thrill of solving a complex math problem that actually helps you achieve some real world end goal is what has given me a newfound appreciation for math.

[nceevij]

Agree teaching is the best way n fastest way to learn something n retain in memory for longest period
