我是一個物理學家和摺紙藝術家。

And today I've been challenged to explain origami and five levels.

而今天我被挑戰解釋摺紙和五級。

If you know a little origami, you might think it's nothing more than simple toys like cranes or cootie catchers.

如果你知道一點摺紙，你可能會認為它不過是一些簡單的玩具，如千紙鶴或捕蠅器。

Out of the vast cloud of origami possibilities, I've chosen five different levels that illustrate the diversity of this art.

在浩瀚的摺紙雲中，我選擇了五個不同的層次，說明了這種藝術的多樣性。

You fooled paper to make different animals like those?

你用紙糊弄了那些不同的動物？

好吧，那麼我們就做一些事情。

But I want to tell you a little bit about origami.

但我想告訴你關於摺紙的一些情況。

It's usually from a square, and the other is It's usually folded with no cuts.

它通常來自一個正方形，另一個是 它通常是摺疊的，沒有切割。

So these guys are folded from an uncut square.

所以這些人是由一個未切割的正方形摺疊而成的。

We're gonna start with a model that every Japanese person learns in kindergarten.

我們要從每個日本人在幼兒園學到的模式開始。

Traditional origami designs over 400 years old.

有400多年曆史的傳統摺紙設計。

So people have been doing what we're about to do for 400 years.

所以人們做我們要做的事情已經有400年了。

Let's fold it in half from corner to corner unfolded and then we'll fold it in half the other direction.

讓我們把它從角到角展開對摺，然後我們再把它從另一個方向對摺。

But we're gonna lift it up, and we're gonna hold the fold with both hands.

但我們要把它抬起來，用兩隻手握住摺子。

We're gonna bring these corners together, making a little pocket, and then this is the trickiest part of this whole design.

我們要把這些角放在一起，做成一個小口袋，然後這是整個設計中最棘手的部分。

So you're gonna put your finger underneath the top layer, and we're gonna try to make that layer fold right along the edge.

所以你要把你的手指放在頂層下面，我們要嘗試讓那層沿著邊緣摺疊。

Now, you see how the sides kind of want to come in as you're doing that.

現在，你看到在你做這個的時候，兩邊是如何想進來的。

It's a part of a lot of origami designs, but it's key to the crane.

它是很多摺紙設計的一部分，但它是起重機的關鍵。

We're gonna hold it between thumb and forefinger.

Reach inside, grab the skinny point that's between the two layers, which are the wings, and I'm gonna slide it out.

伸手進去，抓住兩層之間的瘦點，也就是翅膀，我要把它滑出來。

We'll take the two wings, we spread them out to the side, and you have made your first origami crane.

我們把兩個翅膀，我們把它們展開到一邊，你就做了你的第一個摺紙鶴。

Now, this is a traditional Japanese design.

現在，這是一個傳統的日本設計。

But there are origami designs that have been around so long We're not entirely sure where they're originated.

但有些摺紙設計已經存在了很久，我們並不完全確定它們的起源。

We're gonna learn how to fold a cootie catcher.

我們要學習如何摺疊捉蝨子的工具。

So we'll start with the white side up and we're going to fold it in half from corner to corner and unfold.

是以，我們將從白色的一面開始，我們將把它從角到角對摺，然後展開。

And now we're gonna fold all four corners to the crossing point in the center.

現在我們要把四個角都折到中間的交叉點上。

We'll fold it in half like a book on the folded side.

我們將像書一樣把它折成兩半，在摺疊的一面。

我們將採取其中一個摺疊的角落。

我要把它折起來，穿過所有層。

There's a pocket in the middle We're gonna spread the pocket and bring all four corners together where you have original corners of the square.

中間有一個口袋，我們要把口袋攤開，把四個角並在一起，在這裡你有正方形的原始角。

This is one of the most satisfying moments, I think, Yeah, because it suddenly changes shape.

這是最令人滿意的時刻之一，我想，是的，因為它突然改變了形狀。

Yeah, but there's something else we can do with this model.

是的，但我們可以用這個模型做一些別的事情。

We set it down and push on the middle, Then pop it inside out So that three flaps come up and one stays down.

我們把它放下來，按住中間的位置，然後把它從裡面彈出來，這樣就會有三個擋板升起，一個擋板保持不動。

Because here's a little crow's beak and mouth.

因為這裡有一個小烏鴉的喙和嘴。

Wow, there's thousands of other origami designs.

哇，還有成千上萬的其他摺紙設計。

But these are some of the first people learn, and this was, in fact, one of the first origami designs I learned some 50 years ago.

但這些都是一些最早學習的人，事實上，這是我大約50年前學習的第一批摺紙設計之一。

I think that the people that make them are talented.

我認為做這些東西的人很有天賦。

It's hard seeing the stuff that we've made here.

看到我們在這裡做的東西很難受。

I bet that they could do rocket ships just so much that you can do with them.

我敢打賭，他們可以做火箭船，只是你可以用他們做這麼多。

A lot of origami is animals, birds and things.

很多摺紙都是動物、鳥類和東西。

There's also a branch of origami that is, it's more abstract or geometric called escalations.

還有一個摺紙的分支，是，它更抽象或幾何的，叫升級。

Test relations, like most origami, are folded from a single sheet of paper, but they make patterns like whether it's woven patterns like that are woven patterns like this.

測試關係，就像大多數摺紙一樣，是由一張紙摺疊而成的，但它們做出的圖案，無論是像這樣的編織圖案還是像這樣的編織圖案。

The thing that makes them cool is they're sort of like tiling is.

使它們變得很酷的是它們有點像貼瓷磚是。

It looks like you could put this together by cutting little pieces of paper and sliding them together.

看起來你可以通過裁剪小紙片和滑動它們來拼湊這個。

But there's still one sheet that they weren't cut.

但仍有一張是他們沒有被剪掉的。

這些東西沒有削減，只是摺疊。

We can build these up from smaller building blocks of folds and learn how to fold little pieces and put them together in the same way that tiling like this looks like it's built up of little pieces.

我們可以從較小的摺疊積木中建立這些東西，並學習如何摺疊小塊並把它們放在一起，就像這樣的瓷磚看起來是由小塊建立起來的一樣。

Can you make a fold that starts at the dot?

你能做一個從點開始的摺疊嗎？

It doesn't run all the way across the paper.

Each of these folds is peaked like a mountain, and we call these mountain folds.

這些褶皺中的每一個都是像山一樣的山峰，我們把這些褶皺稱為山形褶皺。

But if I made it the other way, then it's shaped this way.

但如果我把它做成另一種方式，那麼它的形狀就是這樣的。

I'll call it a valley Fold in olive origami.

我把它稱為橄欖摺紙中的山谷摺紙。

There's just mountains and valleys, so all the folds are reversible, so they're all reversible.

只是有山有谷，所以所有的褶皺都是可逆的，所以它們都是可逆的。

And it turns out that in every origami shape that folds flat, it's going to be either three mountains in the valley.

而事實證明，在每一個摺紙形狀中，折平後，要麼是山谷中的三座山。

Or, if we're looking at the backside three valleys in the mountain, they always differ by two.

或者，如果我們看的是山的背面三個山谷，它們總是相差兩個。

這是所有平坦的俄勒岡州的一個規則。

No matter how many folds come together at a point, and I'm gonna show you a building block of test relations, it's called a twist because that center square, as I unfold it twist it twists.

無論多少個摺痕都會在一個點上聚集在一起，我要給你看一個測試關係的構件，它被稱為扭曲，因為那個中心方塊，當我展開它扭曲它就會扭曲。

It, rotates if I had another twist in the same sheet of paper, I can make these folds connect with that.

它，旋轉，如果我在同一張紙上有另一個扭曲，我可以讓這些摺痕與之相連。

And if I had another one up here, I can make all three.

如果我在這上面還有一個，我就可以把這三個都做出來。

And if I had a square array and all the folds lined up, I can make bigger and bigger arrays like these because these are just very large twists in this case is it's an octagon rather than a square.

如果我有一個正方形數組，所有的摺痕都排成一排，我可以做出越來越大的數組，就像這些，因為這些只是非常大的扭曲，在這種情況下是一個八邊形而不是正方形。

But they're arranged in rows and columns.
