and your brain can be broken into two parts.

There's the left half, which is the logical side,

而你的大腦可以分成兩個部分。

左半邊，這是掌控邏輯的一邊，

And so if we had a scale to measure the aptitude of each hemisphere,

所以如果我們有一個尺度去衡量這兩邊，

And for example, this would be somebody who's completely logical.

那麼我們可以繪製我們的大腦。

This would be someone who's entirely intuitive.

譬如，這是一個完全靠邏輯的人的大腦。

So where would you put your brain on this scale?

Some of us may have opted for one of these extremes,

那麼，你會把你的大腦放在這個尺上的哪裡？

but I think for most people in the audience,

有些人可能會選擇其中一個極端，

但我認為，對大多數在台下的人，

with a high aptitude in both hemispheres at the same time.

It's not like they're mutually exclusive or anything.

兩個腦半球同時有著很高的潛力。

不是說它們會互相排斥或什麼的。

And so I consider myself one of these people,

along with most of the other experimental quantum physicists,

But at the same time, we need a good deal of intuition

能把這些複雜的想法串連起來。

但同時，我們也需要很好的直覺

How do we develop this intuition? Well we like to play with stuff.

So we go out and play with it, and then we see how it acts,

我們如何啟發這種直覺呢？嗯，我們喜歡研究東西。

and then we develop our intuition from there.

所以我們會去研究東西，然後我們會看它怎麼反應。

接著我們從中提升我們的直覺力。

that you may have developed over the years

is that one thing is only in one place at a time.

I mean, it can sound weird to think about

像一個事物只能同時出現在一個方位。

one thing being in two different places at the same time,

我的意思是，這聽起來很奇怪去考慮

but you weren't born with this notion, you developed it.

一個事物可以同時出現在兩個不同的地方，

And I remember watching a kid playing on a car stop.

但是你不是天生就有這種概念，你是後天培養的。

He was just a toddler and he wasn't very good at it, and he kept falling over.

我記得看到過一個小孩在阻車器上玩。

But I bet playing with this car stop taught him a really valuable lesson,

他還只是個小朋友，而且非常不擅長玩這個，他一直摔倒。

and that's that large things don't let you get right past them,

但是我打賭跟阻車器玩耍給他上了很有價值的一課，

就是大型的物體不會輕易的讓你穿過，

And so this is a great conceptual model to have of the world,

這是世上擁有的一個很具備概念性的模型，

It'd be a terrible model for a particle physicist,

對於粒子物理學家這會是一個很糟糕的模型，

they play with these little weird particles.

他們研究那些很小的奇怪微粒。

they find they do all sorts of really weird things --

他們發現他們都在做各種很奇怪的事情--

or they can be in two different places at the same time.

And so they wrote down all these observations,

或者他們能同時出現在兩個地方。

and they called it the theory of quantum mechanics.

And so that's where physics was at a few years ago;

然後他們把它起名為量子力學理論。

to describe the large, everyday objects around us.

This didn't really sit well with my intuition,

它來描述那些巨大的、生活周遭的尋常物體。

and maybe it's just because I don't play with particles very often.

這並不是很符合我的直覺認知，

也許只是因為我不太時常研究微粒的緣故吧。

But it didn't sit well with my logical side either.

我的意思是，沒有人看過這些微粒。

Because if everything is made up of little particles

因為如果所有東西都是由微小微粒組成的

then shouldn't everything just follow quantum mechanics?

那不是所有東西都應該符合量子力學嗎？

And so I'd feel a lot better about the whole thing

So a few years ago, I set off to do just that.

所以在幾年前，我開始這麼做。

that has been in a mechanical quantum superposition.

且可以表現得如量子力學解釋那樣。

And you can sort of see this green dot right in the middle.

And that's this piece of metal I'm going to be talking about in a minute.

而且你可以稍微看到這中間的綠點。

And here I'll zoom in a little bit. We're looking right there in the center.

And then here's a really, really big close-up of the little piece of metal.

放大一些看。我們現在看到的是在正中間。

So what we're looking at is a little chunk of metal,

這是非常非常接近地看這塊小金屬。

and it's shaped like a diving board, and it's sticking out over a ledge.

所以我們看到的是這塊小金屬，

它的形狀像潛水板，而且它的周圍稍微凸出一些。

in nearly the same way as you make a computer chip.

我用製造電腦晶片幾乎一樣的手法

I went into a clean room with a fresh silicon wafer,

and then I just cranked away at all the big machines for about 100 hours.

我拿一個矽晶圓進到一個無塵室，

For the last stuff, I had to build my own machine --

然後跟那些機器工作了大約一百個小時。

在最後的時候，我自己做了一個機器

You know how uncomfortable it is to be in a crowded elevator?

I mean, when I'm in an elevator all alone, I do all sorts of weird things,

像是在很擠的電梯裡會感到不適，

我的意思是，當我自己一個人在電梯時，我會做很多奇怪的事，
