WOW. You explain stuff in such an intuitive manner

This should be first hit for Euclidean algorithm

our explanations are similar except I cut the box Into Identical sections

Excellent video.

A new classic here! I've had this video in my Downloads for some time.

This was mind-blowing to watch. I'm amazed at how you could convey everything so neatly and clearly.

love it;❤

Thanks.

Weird how this video was located next to Lemmino's new video

Came here after Leminno video about Kryptos. Nice video! And the puzzle was fun, althought at first I didn't know what to do with the fact that last row is incomplete. But when you think about it, it becomes more or less obvious.

Really enjoyed this video, gave me a new reason to love maths even more! One tiny note: it should be pronounced "Dirishley".

This is fantastic, thank you!

I think this is a WILDLY helpful video. Awesome job.😎

7:25 once you dropped down into the origin my brain immediately made the connection between the inverse square law & what was being talked about previously

At 2:30 you said, “. . . like Pi as the ratio of diameter to circumference”.

This didn't do it for me. I feel as if my understanding has regressed after watching this😢

I don't understand shit she said . 😅

Amazing

Hello Dr. Kate. Loved this video. Previously, I was convinced that on the interval [0,1) the number of reals was equivalent the number of whole numbers and that Cantor's diagonal proof was junk. Your video changed my mind about the former. :) Now the proposition that .999-repeating is identical to 1 has re-entered my life. As I currently understand this video, they aren't equal for .999-repeating never intersects 1.0 in the graph. (But, then again, thinking as I type this, It never passes 1-0 either.) For very-part-time, recreational, arm-chair mathematicians like myself, could you maybe, please, discuss .999-repeating and how it is or isn't the same as one? Thanks much if you do. (Pretty much the same if you take a pass.) In either case, thanks for the video.

Youre a wonderful teacher. I mean it. You made it very suggestive what the answer is so that I could come up with it myself. Brilliantly done and I bet you - now it is mine forever!

Amazing video! I personally think this explanation is much better than the ones shown on AwesomeMath L4

❤

Nn

Great stuff. However, it would have been useful to show an example where there are no common factors except for 1.

So how big would you need these circles to be in order to crack RSA? You know, hypothetically?

you are a legend

This also sort of explains why the golden ratio φ is like the “most irrational number” - its continued fraction ‘address’ consists of only 1s - so all the rational approximations are similarly bad! Since the coefficients are always natural numbers, 1 is the worst possible! Edit: fixed it’s instead of its.

You can get the circumference of the observable universe to a planck length with only 64 digits if I recall

whatttttt this is the most exciting math video that ive seen!!!

Beautiful videos!

I haven't even watched the video yet, but I've been a big fan of these kind of fractals since I was young and always wanted to write a program to generate them. I just wrote a program that finds the circles very well for a very specific example. I'm excited to learn more about three circles tangent to each other lol.

I wish I could say thank you in person. I am a Mechatronics Engineering Student and we are Studying the Routh-Hourwitz Criterion in Control Systems. I'm trying to understand this so I can understand the proof of the Routh-Hurwitz criterion better. I have to say, you are part of the people that make my degree worthwhile. Thanks so much for what you do. Thanks for not giving up on prooving mathematial facts. Thanks for not giving up on intuition. Thanks for not obscuring mathematical concepts . Thanks for making it accessible. Thank you. Thank you. Thank you !!!!😢😢😢😢😢😢😢.

I never thought of continued fractions as binaries.

when you divide by 6 you get 3 remainder 4? what are you dividing? assuming you are dividing 22 by 6, this is giving us 3.6. could you clarify this part as as you stated it gets tricky but you dont explain the workings of this very clearly

Took me a bit to get a proof of multiplication being well defined, but here goes: We have n|a-a' and n|b-b'. We want n|ab-a'b'. Since n|b-b', we get n|a(b-b') since multiplying an arbitrary integer won't change whether it's divisible Since n|a-a', we get n|(a-a')b' for the same reason The sum of 2 things with a common factor will have that same common factor, so n|a(b-b') + (a-a')b' n|ab-ab'+ab'-a'b', distributing the multiplication n|ab-a'b'

"everyone's favorite, pi" Hmmm, not sure I'm familiar. Is that like half of tau, or something? ;P

I LOVED your video named rethinking the real line and now i saw this one and came in to your channel and saw that you are the same person!!! i didnt subscribe 3 months ago but i do now with a smile on my face :)

Everywhere I go with visual representations for math, I ended up seeing infinitely repeating fractals

I LOVE YOUR LETTERS

you're a genius

Is anyone able to help me understand the statement at 13:20? If we take the case of N = 10, which gives quadratic residues mod N of {0,1,4,5,6,9}. The prime divisors of 10 are 2 and 5. The quadratic residues mod 5 are {0,1,4} and those of 2 are {0,1}. x = 5,6 and 9 are all cases where the Fundamental Principle is failing to hold. What am I missing? Is the logic meant to be the other way around?

Thank you very much for the visualizations!

355/113 really is unbelievably accurate. Specifically, it is 294 times more accurate than it is precise. Compare: 2721/1001 for e, which is only 9 times more accurate than it is precise. 22/7 is 16x more accurate than precise, while 19/7 is only 5x more accurate than precise. π just seems to have several inexplicably good simple rational approximations. Heck, even 3/1 is better at approximating π than e.

Thank you so much for making us think

سؤال اتمنى تردي بدري لان بكرا الشرح حقي الحين الارقام513264 منين جبناهن؟!

You showed a visual proof with the triangles showing that it leaves 3 if the gcd is 3 never breaking part the groups which the amount would be the gcd, but I still dont understand why that works or happens, you just showed that it did, but i don't understand why subtracting it from each side leaves the gcd.

This has made me very happy. Fabulous
