Wow, it would be an honor to be on numberphile =) They just made a video talking about transcendental numbers, thats a great opportunity to talk about origami angles =D
Thank you Mori sensei, I hope you do not mind, but I have shared your video with a group of Origami enthusiasts who have been asking how to divide into fifths, thirds, etc. I will let you know how they take it.
Wow, nice way to solve the problem. Only using triangle similarity and Pitagorean theorem. Thanks a lot! I was wondering how to do it and I couldn't figure out xD
Nicely done. God explanations. What about paper divisions like the square of two or two times the square root of three? Are you going to make another video for these ones?
From this video I concluded that a. you are obviously awesome, but I knew that already from your origami videos b. mathematics in this video are for me at least a territory that is as difficult to understand as the exact size of the cosmos. 😓I really wish I could understand these concepts, 😲 great idea to combine paper and writing on a board to explain everything! 👍🏻👍🏻👍🏻 I will now go and attempt to heal my fried brain! I honestly thinks those neurons are crying lol 🙏🏻👌🏻📝
Thank you. I did not realize that this technique was so easy to generalize (facepalm at 1:50). It is EXTREMELY useful for anything that is 2^n * (2^m+x) for n and m natural numbers, and where x is either 1 or -1. This covers most of the divisions I might ever actually want to do, except it is messy for multiples of 11 and 13 (and 19 etc, but those are very rare). Do you know any efficient algorithm for those divisions?
11 is quite difficult to think of an effective way... I know that there are methods with many iterations, which you can get really good approximations. Now, if you want an exact result, you can find 1/3, then, easily you can find 1/6 and 1/12. after you get 1/12, you can find 1/11 and 1/13, but after these many steps, I think you won't have good precision =/.
OMG this is amazing!! Just what I needed! I like how he explained the math, even if it was very very quickly. I needed to divide paper into 96 for the Ryujin 3.5, and 96=2*47, which is not nice. This helps a lot! Thank you!
I did some digging, and youtube provided a solution: watch?v=aAAPgD-y4AQ and also: watch?v=UBTWylW4_TE I have not checked the math myself to make sure they are correct, but why would youtube lie to me?
5 years ago I made a quickhelp guide, including 11th and 13th download it here: mediafire . com / download / favzu8sr3vslv3p / christian_weinert_-_origami_hilfe_v3.0.pdf hope it helps.

Well, that's my formation ;)
I'm a mathematician.
I always wanted to find a video that explains the matematical part of the sheet divisions. Thank You Tadashi!
Why did this video not get more popular, it was great.

Te agradeço milhões de vezes! Você é simplesmente sensacional! Esse vídeo é de gigantesca ajuda para muita gente, incluindo eu, é claro! Blessed Be!!!
Goodness me,I don't understand these mathematics things(except the easy things)!tadashi mori,u r a good mathematician!

Great math! Where did you find all of the answers and parts and things like that
Nice video Tadashi. You are good at math lol
Nicely done. God explanations. What about paper divisions like the square of two or two times the square root of three? Are you going to make another video for these ones?
Oh my God!!! Math!!! O_O Very good video, thanks for sharing. You are a very good mathematician :-D
Great work it's very useful for me
and i hope you post more videos about mathematics in relation to origami
This will be totally helpful for box-pleated pre-creasing
Thanks!
that's excellent ! I am not mathematician and understood everything, even the formulas. :)
how did you get the h/n relationship? do you have a concrete mathematical proof for it?
Your math of origami videos are really intresting and helpful, thanks! :)
Thank you so much your video was so helpful. I figured out how to fold 11ths because of it.
You draw some pretty straight lines, and I liked your drawings in your Draw My Life video. I'm guessing you are good at art as well?
did you try finding the angle of 90-x, then use the polar plane?
Kindly consider another video showing how to compare two fractions 1/8 and 3/9 any random fractions in your way. i wish it will go viral.

I applaud you in this. This is very helpful. Thank you! @tadashi Mori
Thanks tadashi, you're the best!!! :D

That was great!! I always wanted to know how to do this. Thanks.
Tadashi, can you help me get a 60 x 60 grid?
Quick and easy tricks, thanks for the video; It will be very usefull for me that I´m in the way of creation.
You help me so much fir my creations. Thank you!
This is so mathematical. I don't understand a bit of it at all. But if you are a nerd, you would love it.
nice work but the 1/5th is solvable without the use of trigo in a algebric way but nice video and fantastic info tnx Tadashi :)
my brain suddenly bled on the math part
Now I can make a 41x41 grid for Lang's flying katydid...
Now, about the color of the paper…
can u use tracing paper for the darkness dragon ps it is awesome
Sure =), Thanks for sharing the video!
How? I didn't figure out yet.
Corrected the link =)

For 96 grid, you only divide the paper by 3, and the constantly dive those section in half. 3,6,q2,24,48,96
No 96 is 3*2^5. in other words, its a 3x3 grid where each part segment is folded in have 5 times
Very helpful. THANK YOU A LOT!!!!
The link to download untranslated file doesn't work.
Por favor, faz uma versão desse vídeo em português !!!!
Mas mesmo assim o vídeo foi muito bom !!!
Really really helpful
Muito bom! Valeu aê pelas dicas!
Did you just bought a white board and some sketch pens?
ill write it down properly tomorrow and send it
K, Thanks!
Wow
That is so coooooool
I never heard that before
Thanks for the tutorial sir but I wish that u made the video in normal speed rather than hyperlapse 😉🤝
now i know how to divide paper into 3, 5 and 9 but i still dont know how it works maybe if i get better at maths
Actually if you think of it origami is art so yeah he is good at art indeed :)
wheres the part where you divide it in to 7
Thanks!
Quite complicted but helpful.
thanks you so much
explained it all!!!
lol i forgot 😂
still a great video :D
*looks at your origami video*
Hmmm, amazing one.
*looks at your math video, as a fan of constructive geometry*
Aaaabxvsjsj this is awesome
no problem glad to help :D
Helpful ^^
But I like all your videos!
Good
Arg Math I think I'll stick to folding origami with an even amount of pre-creases.
MOREMOREMORE :DDD
my brain: what if i remove one division from 1/1?
That blew my mind... lol
I like you accent
A-Level maths is not helping, though i recognised the double angle formula of tan
I did some digging, and youtube provided a solution: watch?v=aAAPgD-y4AQ and also: watch?v=UBTWylW4_TE
I have not checked the math myself to make sure they are correct, but why would youtube lie to me?

That’s great, thx a lot! 🙏
yes
i knew i'd use mathematics somewhen
sono italiana .. non capisco :(
It's not accurate for even 1/7th of a 15cm paper!
When i see Tan=..... I fell to sleep.
Ohh i get it
i like
Whoa, math
Origami e matematica? pronto a diversão acabou...
2:27????? Just want to fold nice models not do more math thane on school
Some ppl may think asians call this common sense
And 111
Is ti poem
no fair nobody said First!
.........
Im asian too thou but idk dafuq is goin on xD
:O math
too much math lol!
you talk too much.
BORlNG!-_- xD
Corrected the link =)
