We humans have known, for thousands of years,

程度の副詞

just looking at our environment around us,

And not only do they have different properties,

one might reflect light in a certain way,

or not reflect light, or be a certain color, or at

a certain temperature, be liquid or gas, or be a solid.

react with each other in certain circumstances.

And here's pictures of some of these substances.

And all of the ones that I've shown pictures of, here--

and I got them all from this website, right over there--

But we also know that it looks like there's

certain types of air, and certain types of air particles.

And depending on what type of air particles

you're looking at, whether it is carbon or oxygen or nitrogen,

that seems to have different types of properties.

Or there are other things that can be liquid.

Or even if you raise the temperature high enough

You could, if you raise the temperature high enough

Or if you, kind of, if you burn this carbon,

So these are things that we've all, kind of, that humanity

that used to be a philosophical question.

But now we can answer it a little bit better.

And that question is, if you keep breaking down this carbon,

into smaller and smaller chunks, is there

some smallest chunk, some smallest unit, of this stuff,

of this substance, that still has the properties of carbon?

these pure substances that have these specific properties

And in history, people have referred to water

But now we know that water is made up of more basic elements.

C stands for carbon-- I'm just going through the ones that

are very relevant to humanity, but over time, you'll

probably familiarize yourself with all of these.

And that most basic unit, of any of these elements, is the atom.

So if you were to keep digging in, and keep

taking smaller and smaller chunks of this,

eventually, you would get to a carbon atom.

Do the same thing over here, eventually you

You did the same thing over here, eventually,

small, for lack of a better word, particle,

And you wouldn't be able to break that down

for it to still have the properties of lead.

And just to give you an idea-- this is really something

that atoms are unbelievably small, really

In fact, most of me is made out of carbon.

In fact, most of all living things are made out of carbon.

And so if you took my hair-- and so my hair is carbon,

So if you took my hair-- right over here,

my hair isn't yellow, but it contrasts nicely

you wouldn't be able to see it on the screen.

were to ask you, how many carbon atoms wide is my hair?

So, if you took a cross section of my hair, not
