:57:03
Have you checked
all the other elements

:57:04
in the pitch blende?
:57:06
I checked every elements.
There is no the result.

:57:09
Every elements in existence.
:57:11
Uranium and thorium are
the only elements that give off rays.

:57:15
Why do they give off twice
:57:16
as much when they are
in the pitch blende as they do

:57:18
as they were tested separately?
:57:20
Where are those
four missing points?

:57:23
That is what I don't understand.
:57:25
I don't understand.
:57:27
You make the chemical analysis of
:57:29
what is content
in the pitch blende, didn't you?

:57:31
Of course. Could I see it?
:57:32
Yes.
:57:38
Uranium oxide - 75%
:57:40
Chlorium Oxide - 13%
Lead sulfide - 3%

:57:42
Silicon dioxide - 2%
Calcium oxide - 3%

:57:45
Barium oxide - 2%
Iron oxide - 1%

:57:48
Magnesium oxide - 1/990%
:57:50
other extraneous elements
1/1000%

:58:17
Pierre Yes?
:58:19
Our universe is composed of
definitely known substances

:58:22
isn't it?
:58:23
Elements are fixed forever
in earth unchanging

:58:29
we know that, don't we?
:58:31
All of our scientist
based on that

:58:33
All of our science is
based on that. Go on

:58:37
In the beginning
:58:39
man used to think that the world
have only of four elements,

:58:42
earth, air, fire and water.
:58:44
They thought that everything
in their universe

:58:46
could be made out of those.
Yes. Go on.

:58:48
But They were wrong, weren't they?
:58:50
They were wrong.
:58:51
Now we know that
there are 78 elements

:58:56
The elements over there
on the shelves

:58:59
and we believe that there are
some elements still unknown
