00:00:00.709 --> 00:00:02.319
What is the intersection

00:00:02.319 --> 00:00:06.636
between technology, art and science?

00:00:06.636 --> 00:00:08.733
Curiosity and wonder,

00:00:08.733 --> 00:00:11.646
because it drives us to explore,

00:00:11.646 --> 00:00:15.110
because we're surrounded by things we can't see.

00:00:15.110 --> 00:00:16.724
And I love to use film

00:00:16.724 --> 00:00:18.060
to take us on a journey

00:00:18.060 --> 00:00:20.940
through portals of time and space,

00:00:20.940 --> 00:00:23.314
to make the invisible visible,

00:00:23.314 --> 00:00:24.964
because what that does,

00:00:24.964 --> 00:00:26.887
it expands our horizons,

00:00:26.887 --> 00:00:29.348
it transforms our perception,

00:00:29.348 --> 00:00:31.678
it opens our minds

00:00:31.678 --> 00:00:33.642
and it touches our heart.

00:00:33.642 --> 00:00:35.081
So here are some scenes

00:00:35.081 --> 00:00:36.900
from my 3D IMAX film,

00:00:36.900 --> 00:00:39.679
"Mysteries of the Unseen World."

NOTE Paragraph

00:00:39.679 --> 00:00:42.193
(Music)

NOTE Paragraph

00:00:42.193 --> 00:00:43.777
There is movement which is too slow

00:00:43.777 --> 00:00:46.192
for our eyes to detect,

00:00:46.192 --> 00:00:49.082
and time lapse makes us discover

00:00:49.082 --> 00:00:51.790
and broaden our perspective of life.

00:00:51.790 --> 00:00:55.930
We can see how organisms emerge and grow,

00:00:55.930 --> 00:00:59.615
how a vine survives by creeping from the forest floor

00:00:59.615 --> 00:01:02.534
to look at the sunlight.

00:01:03.943 --> 00:01:05.803
And at the grand scale,

00:01:05.803 --> 00:01:10.736
time lapse allows us to see our planet in motion.

00:01:10.736 --> 00:01:13.513
We can view not only the vast sweep of nature,

00:01:13.513 --> 00:01:17.198
but the restless movement of humanity.

00:01:17.198 --> 00:01:20.650
Each streaking dot represents a passenger plane,

00:01:20.650 --> 00:01:22.490
and by turning air traffic data

00:01:22.490 --> 00:01:23.992
into time-lapse imagery,

00:01:23.992 --> 00:01:26.560
we can see something that's above us constantly

00:01:26.560 --> 00:01:28.111
but invisible:

00:01:28.111 --> 00:01:33.655
the vast network of air travel over the United States.

00:01:33.655 --> 00:01:36.826
We can do the same thing with ships at sea.

00:01:36.826 --> 00:01:39.138
We can turn data into a time-lapse view

00:01:39.138 --> 00:01:44.261
of a global economy in motion.

00:01:49.549 --> 00:01:51.123
And decades of data

00:01:51.123 --> 00:01:53.364
give us the view of our entire planet

00:01:53.364 --> 00:01:55.245
as a single organism

00:01:55.245 --> 00:01:58.425
sustained by currents circulating
throughout the oceans

00:01:58.425 --> 00:02:02.580
and by clouds swirling through the atmosphere,

00:02:02.580 --> 00:02:04.849
pulsing with lightning,

00:02:04.849 --> 00:02:07.800
crowned by the aurora borealis.

00:02:07.800 --> 00:02:11.830
It may be the ultimate time-lapse image:

00:02:11.830 --> 00:02:15.862
the anatomy of Earth brought to life.

NOTE Paragraph

00:02:19.441 --> 00:02:21.133
At the other extreme,

00:02:21.133 --> 00:02:24.702
there are things that move too fast for our eyes,

00:02:24.702 --> 00:02:26.850
but we have technology that can look into that world

00:02:26.850 --> 00:02:29.703
as well.

00:02:31.763 --> 00:02:32.863
With high-speed cameras,

00:02:32.863 --> 00:02:34.819
we can do the opposite of time lapse.

00:02:34.819 --> 00:02:36.995
We can shoot images that are thousands of times

00:02:36.995 --> 00:02:40.801
faster than our vision.

00:02:40.801 --> 00:02:44.985
And we can see how nature's 
ingenious devices work,

00:02:44.985 --> 00:02:48.215
and perhaps we can even imitate them.

00:02:50.275 --> 00:02:52.665
When a dragonfly flutters by,

00:02:52.665 --> 00:02:54.462
you may not realize,

00:02:54.462 --> 00:02:57.120
but it's the greatest flier in nature.

00:02:57.120 --> 00:03:01.151
It can hover, fly backwards,

00:03:01.151 --> 00:03:04.476
even upside down.

00:03:04.476 --> 00:03:07.577
And by tracking markers on an insect's wings,

00:03:07.577 --> 00:03:11.252
we can visualize the air flow that they produce.

00:03:11.252 --> 00:03:12.594
Nobody knew the secret,

00:03:12.594 --> 00:03:15.143
but high speed shows that a dragonfly

00:03:15.143 --> 00:03:17.370
can move all four wings in different directions

00:03:17.370 --> 00:03:19.680
at the same time.

00:03:19.680 --> 00:03:21.258
And what we learn can lead us

00:03:21.258 --> 00:03:23.292
to new kinds of robotic flyers

00:03:23.292 --> 00:03:25.110
that can expand our vision

00:03:25.110 --> 00:03:30.924
of important and remote places.

NOTE Paragraph

00:03:32.138 --> 00:03:34.296
We're giants, and we're unaware

00:03:34.296 --> 00:03:36.746
of things that are too small for us to see.

00:03:36.746 --> 00:03:39.722
The electron microscope fires electrons

00:03:39.722 --> 00:03:41.369
which creates images

00:03:41.369 --> 00:03:43.050
which can magnify things by as much

00:03:43.050 --> 00:03:45.496
as a million times.

00:03:45.496 --> 00:03:49.210
This is the egg of a butterfly.

00:03:49.210 --> 00:03:52.544
And there are unseen creatures
living all over your body,

00:03:52.544 --> 00:03:55.259
including mites that spend their entire lives

00:03:55.259 --> 00:03:57.290
dwelling on your eyelashes,

00:03:57.290 --> 00:04:00.722
crawling over your skin at night.

00:04:00.722 --> 00:04:03.750
Can you guess what this is?

00:04:03.750 --> 00:04:06.224
Shark skin.

00:04:07.960 --> 00:04:10.864
A caterpillar's mouth.

00:04:12.170 --> 00:04:15.367
The eye of a fruit fly.

00:04:17.283 --> 00:04:20.247
An eggshell.

00:04:22.070 --> 00:04:24.775
A flea.

00:04:27.293 --> 00:04:31.207
A snail's tongue.

00:04:31.995 --> 00:04:34.473
We think we know most of the animal kingdom,

00:04:34.473 --> 00:04:36.885
but there may be millions of tiny species

00:04:36.885 --> 00:04:40.503
waiting to be discovered.

NOTE Paragraph

00:04:43.151 --> 00:04:45.779
A spider also has great secrets,

00:04:45.779 --> 00:04:47.931
because spider's silk thread is pound for pound

00:04:47.931 --> 00:04:49.683
stronger than steel

00:04:49.683 --> 00:04:51.744
but completely elastic.

00:04:51.744 --> 00:04:53.855
This journey will take us all the way down

00:04:53.855 --> 00:04:55.987
to the nano world.

00:04:55.987 --> 00:04:58.771
The silk is 100 times thinner

00:04:58.771 --> 00:05:02.293
than human hair.

00:05:02.293 --> 00:05:05.020
On there is bacteria,

00:05:05.020 --> 00:05:08.221
and near that bacteria, 10 times smaller,

00:05:08.221 --> 00:05:11.145
a virus.

00:05:11.145 --> 00:05:14.647
Inside of that, 10 times smaller,

00:05:14.647 --> 00:05:17.507
three strands of DNA,

00:05:17.507 --> 00:05:20.897
and nearing the limit of our
most powerful microscopes,

00:05:20.897 --> 00:05:25.859
single carbon atoms.

NOTE Paragraph

00:05:25.859 --> 00:05:27.935
With the tip of a powerful microscope,

00:05:27.935 --> 00:05:29.939
we can actually move atoms

00:05:29.939 --> 00:05:35.827
and begin to create amazing nano devices.

00:05:35.827 --> 00:05:37.819
Some could one day patrol our body

00:05:37.819 --> 00:05:40.050
for all kinds of diseases

00:05:40.050 --> 00:05:44.100
and clean out clogged arteries along the way.

00:05:44.100 --> 00:05:46.945
Tiny chemical machines of the future

00:05:46.945 --> 00:05:50.943
can one day, perhaps, repair DNA.

00:05:50.943 --> 00:05:54.151
We are on the threshold of extraordinary advances,

00:05:54.151 --> 00:05:55.901
born of our drive

00:05:55.901 --> 00:05:59.558
to unveil the mysteries of life.

NOTE Paragraph

00:06:00.618 --> 00:06:03.482
So under an endless rain of cosmic dust,

00:06:03.482 --> 00:06:05.679
the air is full of pollen,

00:06:05.679 --> 00:06:08.753
micro-diamonds and jewels from other planets,

00:06:08.753 --> 00:06:11.478
and supernova explosions.

00:06:11.478 --> 00:06:13.487
People go about their lives

00:06:13.487 --> 00:06:18.641
surrounded by the unseeable.

00:06:18.641 --> 00:06:20.384
Knowing that there's so much around us

00:06:20.384 --> 00:06:21.760
we can see

00:06:21.760 --> 00:06:24.816
forever changes our understanding of the world,

00:06:24.816 --> 00:06:27.205
and by looking at unseen worlds, we recognize

00:06:27.205 --> 00:06:29.264
that we exist in the living universe,

00:06:29.264 --> 00:06:32.312
and this new perspective creates wonder

00:06:32.312 --> 00:06:34.915
and inspires us to become explorers

00:06:34.915 --> 00:06:38.235
in our own backyards.

NOTE Paragraph

00:06:38.235 --> 00:06:40.796
Who knows what awaits to be seen

00:06:40.796 --> 00:06:44.554
and what new wonders will transform our lives.

NOTE Paragraph

00:06:44.554 --> 00:06:50.048
We'll just have to see.

00:06:50.048 --> 00:06:54.952
(Applause)

00:06:54.952 --> 00:07:02.140
Thank you. (Applause)
