:09:00
So it caused scientists to
back up and ask this question.
:09:03
So who sees then? Does the brain see?
Or do the eyes see?
:09:08
And what is reality? Is reality
what we're seeing with our brain...
:09:13
or is reality what
we're seeing with our eyes?
:09:16
And the truth is is that the brain
does not know the difference...
:09:20
between what it sees in its environment
and what it remembers...
:09:23
because the same specific
neural nets are then firing.
:09:27
So then it asks the question.
What is reality?

[ Woman ] We're bombarded
by huge amounts of information...
:09:42
and it's coming into our body,
and we're processing it--
:09:44
coming in through our sense organs,
and it's percolating up and up...
:09:47
- and at each step
we're eliminating information.

:09:51
And finally, what is bubbling up
to consciousness is...
:09:54
the one that's
the most self-serving.
:09:57
[ Man ] The brain processes
400 billion bits of information a second...
:10:01
but we're only aware
of 2,000 of those.
:10:04
But our awareness of those 2,000 bits
of information...
:10:08
arejust about the environment,
our body and about time.
:10:19
[ Rattles ]
:10:27
[ Man ] We're living in a world where
all we see is the tip of the iceberg--
:10:31
the classical tip of an immense
quantum mechanical iceberg.
:10:37
- Hey, wow! You got a lot of shots to develop?
- No.
:10:42
Oh, bummer.
Well, I'll catch you later.
