1:15:01
It could heal.
1:15:03
By destroying unhealthy tissue
1:15:04
it could heal all men of diseases
1:15:08
Like cancer? You?
1:15:11
Yes, Pierre.
It might even do that.
1:15:13
We don't know what things
it might do for people.
1:15:19
But, Marie... Oh, Pierre.
Can't you see
1:15:21
how unimportant little things
like these are compared
1:15:24
to what it might mean?
1:15:26
It might prevent great sicknesses
even deaths. Pierre.
1:15:57
And so they went on
with their work
1:15:59
using every possible precaution.
1:16:02
Marie's fingers healed.
1:16:05
And though
they did not find a way
1:16:06
to separate radium and barium
in a single process
1:16:09
they did discover a method of
removing barium
1:16:12
little by little in
infinite decimal amounts.
1:16:16
Working on the theory
1:16:17
that once the whole of the barium
is removed
1:16:19
nothing could be left but radium.
1:16:35
Here we see the sort of
things they had to do.
1:16:37
This is called crystallization.
1:16:40
When the liquid evaporates
crystals are left.
1:16:43
This was the thing they had to
do over and over again.
