0:00:00.960,0:00:05.404
What is the intersection[br]between technology, art and science?

0:00:06.769,0:00:08.875
Curiosity and wonder,

0:00:08.899,0:00:11.622
because it drives us to explore,

0:00:11.646,0:00:14.272
because we're surrounded[br]by things we can't see.

0:00:15.110,0:00:18.036
And I love to use film[br]to take us on a journey

0:00:18.060,0:00:20.916
through portals of time and space,

0:00:20.940,0:00:23.554
to make the invisible visible,

0:00:23.578,0:00:24.940
because what that does,

0:00:24.964,0:00:26.863
it expands our horizons,

0:00:26.887,0:00:29.547
it transforms our perception,

0:00:29.571,0:00:31.654
it opens our minds

0:00:31.678,0:00:32.975
and it touches our heart.

0:00:33.944,0:00:36.743
So here are some scenes[br]from my 3D IMAX film,

0:00:36.767,0:00:38.591
"Mysteries of the Unseen World."

0:00:39.353,0:00:41.775
(Music)

0:00:41.799,0:00:46.229
There is movement which is too slow[br]for our eyes to detect,

0:00:46.253,0:00:49.380
and time lapse makes us discover

0:00:49.404,0:00:51.766
and broaden our perspective of life.

0:00:51.790,0:00:54.288
We can see how organisms emerge and grow,

0:00:56.042,0:00:59.677
how a vine survives by creeping[br]from the forest floor

0:00:59.701,0:01:01.284
to look at the sunlight.

0:01:04.117,0:01:05.779
And at the grand scale,

0:01:05.803,0:01:08.884
time lapse allows us to see[br]our planet in motion.

0:01:10.875,0:01:13.700
We can view not only[br]the vast sweep of nature,

0:01:13.724,0:01:15.946
but the restless movement of humanity.

0:01:17.346,0:01:20.626
Each streaking dot[br]represents a passenger plane,

0:01:20.650,0:01:24.191
and by turning air traffic data[br]into time-lapse imagery,

0:01:24.215,0:01:26.536
we can see something[br]that's above us constantly

0:01:26.560,0:01:28.277
but invisible:

0:01:28.301,0:01:31.594
the vast network of air travel[br]over the United States.

0:01:33.872,0:01:36.251
We can do the same thing[br]with ships at sea.

0:01:36.826,0:01:41.598
We can turn data into a time-lapse view[br]of a global economy in motion.

0:01:49.676,0:01:53.340
And decades of data give us[br]the view of our entire planet

0:01:53.364,0:01:55.569
as a single organism

0:01:55.593,0:01:58.831
sustained by currents circulating[br]throughout the oceans

0:01:58.855,0:02:02.952
and by clouds swirling[br]through the atmosphere,

0:02:02.976,0:02:04.825
pulsing with lightning,

0:02:04.849,0:02:06.675
crowned by the aurora Borealis.

0:02:07.937,0:02:10.157
It may be the ultimate time-lapse image:

0:02:12.171,0:02:14.195
the anatomy of Earth brought to life.

0:02:19.599,0:02:21.265
At the other extreme,

0:02:21.289,0:02:24.678
there are things that move[br]too fast for our eyes,

0:02:24.702,0:02:27.965
but we have technology[br]that can look into that world as well.

0:02:31.763,0:02:32.906
With high-speed cameras,

0:02:32.930,0:02:34.961
we can do the opposite of time lapse.

0:02:34.985,0:02:36.306
We can shoot images

0:02:36.330,0:02:38.779
that are thousands of times[br]faster than our vision.

0:02:41.001,0:02:44.961
And we can see how nature's[br]ingenious devices work,

0:02:44.985,0:02:47.143
and perhaps we can even imitate them.

0:02:50.648,0:02:52.641
When a dragonfly flutters by,

0:02:52.665,0:02:54.700
you may not realize,

0:02:54.724,0:02:56.923
but it's the greatest flier in nature.

0:02:56.947,0:02:59.439
It can hover, fly backwards,

0:03:01.391,0:03:02.541
even upside down.

0:03:04.476,0:03:07.553
And by tracking markers[br]on an insect's wings,

0:03:07.577,0:03:10.247
we can visualize the air flow[br]that they produce.

0:03:11.326,0:03:12.667
Nobody knew the secret,

0:03:12.691,0:03:15.300
but high speed shows that a dragonfly

0:03:15.324,0:03:17.808
can move all four wings[br]in different directions

0:03:17.832,0:03:19.109
at the same time.

0:03:19.680,0:03:23.268
And what we learn can lead us[br]to new kinds of robotic flyers

0:03:23.292,0:03:25.086
that can expand our vision

0:03:25.110,0:03:27.137
of important and remote places.

0:03:32.392,0:03:33.663
We're giants,

0:03:33.687,0:03:36.722
and we're unaware of things[br]that are too small for us to see.

0:03:36.746,0:03:41.345
The electron microscope[br]fires electrons which creates images

0:03:41.369,0:03:44.328
which can magnify things[br]by as much as a million times.

0:03:45.416,0:03:47.102
This is the egg of a butterfly.

0:03:49.455,0:03:52.520
And there are unseen creatures[br]living all over your body,

0:03:52.544,0:03:55.235
including mites[br]that spend their entire lives

0:03:55.259,0:03:57.266
dwelling on your eyelashes,

0:03:57.290,0:03:59.169
crawling over your skin at night.

0:04:00.722,0:04:02.423
Can you guess what this is?

0:04:04.010,0:04:05.114
Shark skin.

0:04:07.960,0:04:09.355
A caterpillar's mouth.

0:04:12.409,0:04:13.988
The eye of a fruit fly.

0:04:17.283,0:04:18.316
An eggshell.

0:04:21.950,0:04:22.975
A flea.

0:04:27.360,0:04:28.719
A snail's tongue.

0:04:32.098,0:04:34.449
We think we know[br]most of the animal kingdom,

0:04:34.473,0:04:36.968
but there may be millions of tiny species

0:04:36.992,0:04:38.515
waiting to be discovered.

0:04:42.992,0:04:45.755
A spider also has great secrets,

0:04:45.779,0:04:49.493
because spiders' silk thread[br]is pound for pound stronger than steel

0:04:49.517,0:04:51.000
but completely elastic.

0:04:51.744,0:04:55.184
This journey will take us[br]all the way down to the nano world.

0:04:55.987,0:05:00.101
The silk is 100 times thinner[br]than human hair.

0:05:02.293,0:05:04.996
On there is bacteria,

0:05:05.020,0:05:08.197
and near that bacteria, 10 times smaller,

0:05:08.221,0:05:09.351
a virus.

0:05:11.291,0:05:14.623
Inside of that, 10 times smaller,

0:05:14.647,0:05:16.402
three strands of DNA.

0:05:17.743,0:05:21.052
And nearing the limit[br]of our most powerful microscopes,

0:05:21.076,0:05:23.218
single carbon atoms.

0:05:25.787,0:05:27.911
With the tip of a powerful microscope,

0:05:27.935,0:05:30.132
we can actually move atoms

0:05:30.156,0:05:33.062
and begin to create amazing nano devices.

0:05:35.827,0:05:39.896
Some could one day patrol our body[br]for all kinds of diseases

0:05:39.920,0:05:42.655
and clean out clogged arteries[br]along the way.

0:05:44.100,0:05:47.060
Tiny chemical machines of the future

0:05:47.084,0:05:49.855
can one day, perhaps, repair DNA.

0:05:51.084,0:05:54.127
We are on the threshold[br]of extraordinary advances,

0:05:54.151,0:05:57.539
born of our drive[br]to unveil the mysteries of life.

0:06:00.554,0:06:03.458
So under an endless rain of cosmic dust,

0:06:03.482,0:06:05.575
the air is full of pollen,

0:06:05.599,0:06:07.235
micro-diamonds and jewels

0:06:07.259,0:06:10.842
from other planets[br]and supernova explosions.

0:06:11.573,0:06:15.704
People go about their lives[br]surrounded by the unseeable.

0:06:18.590,0:06:21.638
Knowing that there's so much[br]around us we can't see

0:06:21.662,0:06:24.792
forever changes[br]our understanding of the world,

0:06:24.816,0:06:26.632
and by looking at unseen worlds,

0:06:26.656,0:06:29.408
we recognize that we exist[br]in the living universe,

0:06:29.432,0:06:32.288
and this new perspective creates wonder

0:06:32.312,0:06:34.891
and inspires us to become explorers

0:06:34.915,0:06:36.213
in our own backyards.

0:06:38.602,0:06:41.012
Who knows what awaits to be seen

0:06:41.036,0:06:43.583
and what new wonders[br]will transform our lives.

0:06:44.727,0:06:46.172
We'll just have to see.

0:06:49.674,0:06:54.427
(Applause)

0:06:54.451,0:06:55.625
Thank you.

0:06:55.649,0:06:58.720
(Applause)
