:21:00
Now, these tiny little vibrations...
:21:03
are caused by dozens of grooves
which are cut into the disc...
:21:07
and they go all the way up the arm
to a great big horn which amplifies it.
:21:12
You know, makes it louder! Like this.
:21:15
And voilà. A song. See?
:21:25
Good day.
:21:39
I'm sorry. Oh, my God.
:21:44
It's just a little snake.
:21:47
It's a lizard.
:21:50
Yes.
:21:52
Now, sound.
:21:56
How can I describe it to you?
:21:58
Sound is like big waves at the beach,
you see...
:22:01
because sound travels in waves
just like light.
:22:03
-I'm not going too fast for you, am I?
-No. Light travels as particles.
:22:07
Light travels as particles and waves.
:22:12
How can light travel simultaneously
in two different ways?
:22:18
Space tells matter how to move...
:22:20
and matter tells space how to curve.
:22:24
Mademoiselle, you must be
a student of the sciences.
:22:28
Yes. I am to study
at the Sydney University.
:22:31
Fascinating. You got a scholarship?
:22:33
Not exactly. I won a prize.
:22:35
The old high school science prize?
:22:37
It was a Nobel Prize,
1903, Applied Physics.
:22:41
-Really?
-You see...
:22:42
I think that
if we could control the ionizing radiation...
:22:46
of the spontaneous disintegration
of uranium isotopes...
:22:51
we could harness the forces of nature.
:22:54
Splitting atoms.
:22:56
You've heard of the theory
to split the nucleus of an atom?
:22:59
I've split one once.
