1:09:04
And so the work went on
until presently
1:09:07
everything had been removed
1:09:08
from the tons of ore
except two final elements
1:09:12
one was barium and the other
1:09:14
which they had began to
think of it
1:09:15
in their heart
as their own element
1:09:17
was the precious illusive radium.
1:09:20
Pierre and Marie thought that
1:09:22
the end of their task
must surely be in sight.
1:09:25
All that was now left was to
separate these two survivors
1:09:30
barium and radium.
1:09:32
This was the problem to
separate barium
1:09:35
and radium somehow or other.
1:10:06
No separation.
1:10:11
No separation. No separation.
1:10:21
September the 12th 1899.
1:10:24
Reduction of pitch blende
nearly finish.
1:10:26
Only barium and radium remain.
1:10:28
The next separation
will give radium.
1:10:32
November the 8th, 1899.
1:10:34
First experiment. No separation.
1:10:37
November the 10th, 1899.
1:10:39
Second experiment. No separation.
1:10:42
July the 16th, 1900.
1:10:44
Four hundred
and fifty eight experiments.
1:10:47
Radium still refuses to separated
from barium.
1:10:52
Alright, then, radium wouldn't be
separated from barium.
1:10:56
We've done all we can
1:10:57
and more more than
most people would have done
1:10:59
thanks to your tenacity
but it's useless.
