  [00:00.00]Lesson  4   Atom

[00:01.95]原子

[00:03.89]The really strange thing about atoms is that most of us will never see one.

[00:08.87]原子最奇特之处在于绝大多数人永远也无法看到它。

[00:13.84]Atoms are so small that it's impossible to see one with the naked eye.

[00:18.47]原子很小,人的肉眼无法看到。

[00:23.09]In fact.atoms are so small

[00:28.66]that it's impossible to see one with any ordinary microscope.

[00:32.48]实际上,原子小到用普通显微镜都无法观察得到。

[00:36.31]How small is an atome?

[00:38.49]原子有多微小呢?

[00:40.67]An atom is about one-millionth the thickness of a human hair!

[00:44.64]它只有人的头发直径的百万分之一!

[00:48.61]The tiniest speck 1 of dust that you could see under an ordinary microscope

[00:57.39]would still contain about ten billion atoms!

[01:00.67]你在普通显微镜下看到的最微上的尘埃颗粒仍然会包含着大约100亿颗原子!

[01:03.95]Atoms are the smallest possible part of any material.

[01:07.53]原子是构成所有物质的最小单位。

[01:11.11]For example,if you took a copper 2 penny and cut it in half,

[01:15.43]例如,如果你把一分面额的铜币切割成两半,

[01:19.75]and then kept cutting it in half until you were down

[01:25.52]to the smallest possible bit of copper,that would be an atom.

[01:29.16]然后一直这样分割下去直到不能再分为止,那就可能出现的最小的铜粒就是原子啦。

[01:32.79]Electrons and Protons

[01:35.52]电子和质子

[01:38.25]There are things that are actually even smaller than atoms.

[01:41.63]其实还有比原子更小的东西。

[01:45.01]What are those?

[01:46.70]是什么东西?

[01:48.38]They are the things that make up the atom,such as electrons and protons.

[01:52.56]就是那些构成原子的东西,比如电子和质子。

[01:56.74]Is there anything that is smaller than electrons and protons?

[01:59.82]还有比电子和质子更小的东西吗?

[02:02.91]Of course there is.

[02:04.68]当然有了,如果我们能够做到的话,

[02:06.46]Things can be divided and broken down into indefinitely small parts if we can.

[02:11.13]物质可以被分割或分解成无穷小的部分。

[02:15.81]I really don't want to know about this.Physics gives me a headache.

[02:19.44]我不想知道这些事情。这些物理概念真让我头疼。

[02:23.07]Electrons and Protons

[02:27.91]电子和质子

[02:32.74]There are things that are actually even smaller than atoms.

[02:36.12]其实还有比原子更小的东西。

[02:39.50]What are those?

[02:41.03]是什么东西?

[02:42.56]They are the things that make up the atom,such as electrons and protons.

[02:46.79]就是那些构成原子的东西,比如电子和质子。

[02:51.02]Is there anything that is smaller than electrons and protons?

[02:54.05]还有比电子和质子更小的东西吗?

[02:57.08]Of course there is.

[02:58.86]当然有了,

[03:00.64]Things can be divided and broken down into indefinitely small parts if we can.

[03:05.36]如果我们能够做到的话,物质可以被分割或分解成无穷小的部分。

[03:10.09]I really don't want to know about this.Physics gives me a headache.

[03:22.17]我不想知道这些事情。这些物理概念真让我头疼。
