那些你看不見的東西 是怎樣變得看起來很有趣。

程度副詞

how something you can't see can be so much fun to look at.

你們將會經歷一次全新的、可應用的

You're about to experience a new, available

而且是令人興奮的技術， 使我們進而重新思考

and exciting technology that's going to make us rethink

我們是如何在生活中運用防水技術

其中一邊我們塗上了奈米技術噴霧

that we've coated half with a nanotechnology spray

這個噴霧幾乎所有材料都能適用

that can be applied to almost any material.

那麼，這裏有一塊未經噴塗的煤渣磚

你可以看出它是有孔、可以滲透的，所以能吸收水分

and you can see that it's porous, it absorbs water.

The rounder it is, the more hydrophobic it is,

如果它真的特別的圓，那它就是超潑水

and if it's really round, it's superhydrophobic.

一輛剛剛上了蠟的車，上頭的水分子會下降

A freshly waxed car, the water molecules slump

一面擋風玻璃表層則大約是110度

A windshield coating is going to give you about 110 degrees.

但你現在看到，在這裡的是160到175度，

But what you're seeing here is 160 to 175 degrees,

and anything over 150 is superhydrophobic.

然後我讓你們猜一下有塗過的是哪一個

當你有奈米技術和奈米科學的時候，

When you have nanotechnology and nanoscience,

隨即發生的是，我們現在有辦法

what's occurred is that we're able to now

look at atoms and molecules and actually control them

The way you measure nanotechnology is in nanometers,

and one nanometer is a billionth of a meter,

如果你有一個奈米顆粒 是一毫微米的厚度，

if you had a nanoparticle that was one nanometer thick,

然後將它一排排並排起來， 一共有50,000個，

and you put it side by side, and you had 50,000 of them,

然後它還不只是對水才有作用而已

And it's not just water that this works with.

很多以水為基底的材料都可以的，比如混凝土

It's a lot of water-based materials like concrete,

你也看到了，這兩邊是不一樣的。

我們拿了一塊玻璃板 並在它的外緣上做塗層

we've taken a pane of glass and we've coated the outside of it,

我們把它嵌入奈米技術塗層的框架裏

we've framed it with the nanotechnology coating,

現在我們要把這個綠色的水倒入中間

and we're going to pour this green-tinted water inside the middle,

你會看到，水會在玻璃板上分散開

and you're going to see, it's going to spread out on glass

只不過當它碰上邊緣的塗層，它就停下來了

except when it hits the coating, it stops,

那麼現在怎麼樣了呢? 發生什麼呢?

So what's going on here? What's happening?

這些顆粒會形成一個 非常粗糙而且凹凸的表層

that form a very rough and craggly surface.

你覺得它很光滑，不過實際上不是

You'd think it'd be smooth, but it's actually not.

And it has billions of interstitial spaces,

而這些空隙呢，與其他的奈米顆粒一起

and those spaces, along with the nanoparticles,

這相當於在上面撐起一層空氣保護傘

這層空氣就是水會碰到的那個表層

and that layer of air is what the water hits,

泥漿一碰到、混凝土一碰到，就立馬滑落。

the mud hits, the concrete hits, and it glides right off.

你會看到一層銀色的塗層在反光

you can see a silver reflective coating around it,

is the layer of air that's protecting the water

不受水的侵襲，所以就會保持乾燥

那這個技術到底有哪些用處呢？

我是指，你們很多人現在可能在想

I mean, many of you right now are probably going through your head.

每個看到這個技術的人都會很興奮，然後說

Everyone that sees this gets excited, and says,

“哦，我可以用它來做這個、這個還有這個。”

"Oh, I could use it for this and this and this."

那我們今天也確實看到了這個作用

because if you don't have water, you don't have ice.

Without water, the bacteria won't survive.

還能用在任何需要自動清潔、耐髒汙的東西上面

And it could be things that need to be self-cleaning as well.

要怎麼幫助你們在工作領域上做出變革

could help revolutionize your field of work.

我現在要向你們展示最後一樣，

And I'm going to leave you with one last demonstration,

不過在此之前，我想要說謝謝你們

but before I do that, I would like to say thank you,

It's going to happen. Wait for it. Wait for it.

Chris Anderson：你們大家沒聽說過 我們會把 TED 中的 Design 給刪掉了嗎？（笑）

Chris Anderson: You guys didn't hear about us cutting out the Design from TED? (Laughter)
