"When you sit in a chair like I'm sitting in this chair right now"

"當你坐在椅子上，就像我現在坐在這把椅子上一樣&quot。

"I'm actually hovering over this chair"

"我'其實是在這把椅子上徘徊&quot。

"but actually my butt is hovering above the chair by this

"但實際上我的屁股是懸停在椅子上面的這一點

just tiny tiny amout" "because of the electrons of my body"

只是微小的微小的amout""因為我身體的電子&quot。

"because the electrons of my butt" "are repelling the electrons of this chair"

因為我屁股的電子""正在排斥這把椅子的電子&quot。

"it's not us actually touching the subatomic material of the object"

"它'不是我們真正接觸到物體的亞原子材料&quot。

Is that really true? Does it mean that MC Hammer has just been singing about physics all along?

真的是這樣嗎？難道說MC Hammer只是一直在唱物理學？

"Can't touch this !!"

"Can't touch this！&quot。

Alas, this doesn't take into account the fact that the universe is quantum mechanical

唉，這並沒有考慮到宇宙是量子力學的事實。

For example, you probably know that electrons behave like spread-out waves

例如，你可能知道電子的行為就像散開的波一樣

and from chemistry, you probably also know

而從化學上，你可能也知道

that it's perfectly fine for two negatively charged electrons

它是完全正常的兩個負電荷電子。

to share the same energy level of an atom or a molecule

同位素

as long as they have their intrinsic spins oriented in opposite directions

只要它們的自旋方向相反就可以了

So, even though electrons repel each other

所以，儘管電子之間相互排斥

their wave packets can overlap.

其波包可以重疊。

For example, check out this image of a ring of iron atoms

例如，看看這張鐵原子環的圖片。

sitting on a surface of copper.

坐在銅的表面上。

see the overlap of the spread out electrons? Now, would you call that touching?

看到這些散開的電子的重疊了嗎？現在，你會把這叫做觸摸嗎？

If you look at a dictionnary, touch is usually defined

如果你看一下字典，觸摸的定義通常為

as physical contact. Well, contact is defined as

作為身體接觸。那麼，接觸被定義為

touching physically. Not much help.

身體上的接觸。沒有什麼幫助。

But most of people have this intuitive idea that

但大多數人都有這樣的直觀想法，即

touch is something like two solid objects

觸覺

so close together there is no space between them.

捱得很近，中間沒有空間。

The trouble is this doesn't have anything to do with overlapping

問題是，這與重疊沒有任何關係。

waves which, as we know, are how electrons actually behave.

我們知道，這就是電子的實際行為。

So, it seems that touch is a word that may just be

所以，看來，觸摸這個詞，可能只是

incapable of describing the actual universe as we understand it today.

無法描述我們今天所理解的實際宇宙。

Either that, or we should change our notion of touch

要不，我們就應該改變我們的觸摸概念

to mean interaction at short distance which is really what happens

意思是指短距離的交流，這才是真實的情況。

between electrons when you sit on a chair.

當你坐在椅子上時，電子之間。

But, regardless of whether or not we ever actually touch anything

但是，不管我們是否真正接觸過任何東西。

I think that when we talk about the electromagnetic repulsion

我想，當我們談論電磁斥力的時候

of your butt and your chair, what we are really trying to say is

你的屁股和你的椅子，我們真正想說的是... ...

Hey! Remember how cool it is that we are made of atoms and molecules

還記得我們是由原子和分子組成的嗎？

and that other people made of atoms and molecules

和其他人的原子和分子組成。

were clever enough to figure that out.

聰明的人都能想到這一點。

Now, that is touching.

現在，這是感人的。
