Per quelli che tendono la loro immaginazione

che immaginano un futuro dove la tecnologia

serve il bene più grande

la loro missione è la nostra missione

Alla Lockheed Martin, non dimentichiamo mai

per chi lavoriamo

Sembra una città normale

Sappiamo cosa vedremo su queste strade, dentro queste mura

O così pensiamo

Le persone che vivono in questo condominio

sono circondate da cose che non possono vedere

Tutti noi siamo

Ovunque

Le cose sono troppo lente per essere rilevate dai nostri occhi

o troppo veloci da seguire

Da cose che possono essere viste

solo attraverso le onde luminose per noi invisibili

Ciao Mamma

Divertiti

Un giorno nelle loro vite sarebbe molto diverso

se potessero vedere tutte le onde luminose intorno a loro

O vedere altri mondi intorno a noi

che sono troppo piccoli

microscopici...

o ancora più piccoli

fino al cuore della materia stessa

Immagina se, per un giorno

potessimo vedere cio' che loro non possono

tutto ciò che è troppo lento, troppo veloce, troppo piccolo

O semplicemente invisibile

Sarebbe cambiata per sempre la nostra comprensione

del pianeta su cui viviamo

Oggi vedremo oltre i limiti della visione umana

Normalmente, vediamo le onde luminose

che rimbalza sugli oggetti

Si irradiano nei nostri occhi

e sulla nostra retina nella parte posteriore dei nostri occhi

dove l'immagine appare apovolta e all'indietro

È trasformata in impulsi elettrici

quella corsa al cervello....

che ci permette di vedere quello di cui abbiamo bisogno per sopravvivere

Ma ci manca molto

Vediamo solo l'arcobaleno di onde luminose chiamate luce visibile

Ma questa è solo una piccola parte dei milioni di lunghezze d'onda

nel vasto spettro elettromagnetico

Parte di questa luce invisibile

ha le onde più lunghe di quelle dell'arcobaleno

come gli infrarossi

micronde....

e le onde radio

Le altre sono piu' brevi

incluse le ultraviolette...

i raggi X....

e gamma.

Queste onde si irradiano dal sole

dallo spazio

da ogni cosa intorno a noi

Sul tetto, ci sono creature

che possono vedere altre onde luminose

Un'ape può vedere il mondo attraverso la luce ultravioletta

Può vedere i contrassegni UV sui fiori

che guida api e gli altri impollinatori

diritti al loro polline

Tutto questo è invisibile per te

Hai appena visto un'ape che si nutre del nettare

Anche una zanzara ha un vantaggio su di te

Attraverso la visione a infrarossi,

può vedere i modelli di calore sul tuo corpo

Macchie più calde significano più sangue vicino alla superficie

Abbiamo telecamere che mostrano come può vedere una zanzara

rivelando ciò che è caldo...

e cosa non lo è

The brighter something looks,

the hotter it is.

Some wavelengths can pass right through objects.

Wonder what's going on inside the apartment building?

Gamma rays can show you.

With X-ray vision, you could see an egg hidden within a quail...

the mechanics of an animal in motion...

and what's going on inside anyone's body.

Radio waves can also pass through us.

An MRI can use them,

along with magnetic energy,

to show your heart beating.

The more invisible light waves we can see,

the more secrets we uncover about the world around us.

But that's only the beginning.

Some things happen too slowly for our eyes.

In the 1930s, an amateur scientist in Chicago

wanted to see how flowers move.

John Nash Ott had the idea of shooting a single frame of film

at regular intervals...

15 minutes apart.

By projecting the pictures at the normal speed of movies--

24 frames per second-- Ott saw that flowers move dramatically

as they react to light.

He also had some fun.

[orchestra plays lively classical melody]

We call it "time-lapse photography,"

and through it, we discover movement

Where our eyes see none.

We can see how organisms emerge and grow.

How a vine survives by creeping from the forest floor

to reach the sunlight.

A passion-flower vine tosses its tendrils

like a grappling hook,

wrenches itself up,

and throws open its sun-catching blossom.

We can see living things decompose...

providing resources that allow new life to flourish.

Dead matter can be food for slime molds,

among the simplest life-forms.

Time-lapse shows that they are constantly on the move.

One slime mold is astonishingly complex.

When individual cells run out of food,

they group together and form stalks

with spores at the top.

The spores can be picked up by the wind or passersby

and carried to a place with more food.

Good boy.

On a grander scale,

time-lapse allows us to see our planet in motion.

We can view not only the vast sweep of nature...

but the restless movement of humanity.

Each streaking dot represents a passenger plane.

By turning air traffic data into time-lapse imagery,

we can see something that's above us constantly...

but invisible--

the vast network of air travel

over the United States.

We can do the same thing with ships at sea--

turn data into a time-lapse view.

Decades of data give us a view of our entire planet

as a single organism,

sustained by currents circulating through the sea...

by moisture and warmth,

swirling through the atmosphere,

pulsing with lightning,

adorned by the Aurora Borealis.

It may be the ultimate time-lapse image--

the anatomy of Earth, brought to life.

[narrator] At the other extreme of time,

there are things that happen too fast for our eyes.

But we have technology to see that world, too.

of the Massachusetts Institute of Technology.

His stroboscope light, my friends, is really something,

and it's put' the "super" in super-speed photography.

While normally film runs through the average movie camera

at .90 feel' a minute,

Edgerton's flicker box can handle 125 feel' a second.

In normal speed movies, a bullet' shot' from the muzzle

of a high-pa wered air gun is invisible-

Now Edgerton really photographs a bullet' in flight'-

Watch it come in from the left'-

Here, fascinating patterns of movement.

And when you recall that all the action of this bulb smashing

actual! y took place in the fraction of a second,

you realize that here is speed in movie photography, indeed!

[narrator] High-speed cameras do the opposite of time-lapse.

They shoot images thousands,

or even millions of times faster than our vision.

When played back at 24 images per second...

they show us remarkable things we normally miss.

When you see drops hit the water,

here's what you don't see.

Every drop bounces like a ball.

Held together by surface tension,

it continues to get smaller

and smaller.

This happens every time a raindrop hits a puddle.

A hundred times every second,

lightning strikes somewhere on Earth.

Little was known about lightning

till high-speed cameras turned the research upside down.

Literally.

What our eyes see is energy flowing downward

from the clouds.

Now we can see that electricity also moves

upward from the ground.

Se possiamo vedere i fulmini

We can see almost anything that's lightning-fast.

When a dragonfly flutters by,

potresti non rendertene conto

it's the greatest flyer in nature.

It can hover...

fly backwards...

and even upside down.

No one knew the secret.

But high speed shows that a dragonfly can move

all four wings in different directions

at the same time.

No aircraft can do this.

If we can see how nature's ingenious devices work...

we can imitate them.

By tracking markers on an insect's wings,

we can visualize the airflow they produce.

What we learn could lead us to new kinds of robotic flyers

that expand our vision of important events

in remote places.

How many secrets remain to be discovered

in the super-fast worlds of nature?

We move through the landscape like giants,

unaware of the wonders too small for us to see.

Long ago, we noticed that a glass sphere

made things appear larger.

Grinding it down into a lens magnified objects even more.

Stacking lenses in a tube greatly multiplied the effect,

and the compound microscope was born.

It let us peer into a world we'd never seen before.

Suddenly, we could see creatures in common pond water

that we didn't even know existed.

But there is a limitation to the compound microscope.

We can't see down into the scales of the butterfly's wing

because visible light waves are too big.

Everything smaller goes out of focus.

We needed a microscope

that used something smaller than visible light.

The scanning electron microscope fires electrons,

smaller than atoms, creating an image

that magnifies things by as much as a million times.

It shows that deep inside the tiny scales

of a butterfly's wing

are even smaller structures

which are shaped to reflect only pure blue light waves,

giving the wings of a Morpho butterfly

one of the most brilliant blues in nature.

Il microscopio elettronico rivela cose

bizzarre e allo stesso tempo belle

Indovina di cosa si tratta

l'uovo di una farfalla

la pelle di uno squalo

bocca di un bruco

L'occhio di una mosca della frutta

Un guscio d'uovo

Un gambo di pomodoro

Una pulce

La lingua di una lumaca

Pensiamo di sapere di più del regno animale

ma potrebbero esserci milioni di piccole specie

che aspettano di essere scoperte

Anche l'aria che respiriamo

è piena di cose non visibili :

polline

scaglie di pelle....

parti di insetti....

peli di animali

C'è anche materia dallo spazio

compresi micro diamanti e gioielli

da altri pianeti e da esplosioni di supernova

30.000 tonnellate di polvere spaziale

cade sulla Terra ogni anno

Alcune di questi sono inalate ad ogni respiro

da tutti gli esseri viventi sulla Terra

compreso te

And it gets even more personal.

There are unseen creatures living all over your body,

possibly including mites that spend their entire lives

dwelling on your eyelashes,

crawling with their eight legs over your skin at night.

They're on some of you...

right now.

When you're unlucky enough to get a case of head lice,

this is what's living in your hair.

More than 1,000 strains of bacteria

could be in your belly button.

This is what causes stinky feet.

Some 32 million bacteria live on your skin,

most of them harmless

or even good for you.

There are far more organisms living on you

than there are people on Earth.

It turns out that the world of the really small

is full of clever things we can use.

The surface of a lotus leaf repels almost any liquid.

Whao ! È così fico !

A super-close look reveals the secret:

tiny hair-like bumps that cause drops

to roll right off the leaf.

Maybe we could mimic this,

making a coating to shield airplanes from ice buildup.

Once, it was a mystery

how a gecko could walk up smooth glass.

Gecko feet are covered by half a million tiny bristles

that branch into split ends,

each with a pad on the tip.

The structures build up an electrical charge

that attracts them to the surface,

adding up to incredible sticking power

and a model for a new kind of robot

that could climb almost anything.

A spider also harbors secrets.

Spider silk thread is, pound for pound, stronger than steel

and yet completely elastic.

Imagine what we might build

if we could produce a synthetic version.

The first step is getting a closer look at spider silk.

The journey could take us all the way down to what we call

the nanoworld.

The silk is 100 times thinner than a human hair.

On it, there's bacteria.

Near the bacteria, ten times smaller, a virus.

Inside that, ten times smaller,

three strands of its DNA.

And nearing the limit of our most powerful microscopes,

single carbon atoms.

Four of them are the size of one nanometer.

Welcome to the nanoworld.

This incomprehensibly small place is the new frontier.

Exploring it will lead to huge changes in our lives.

Our most advanced microscopes can now see this:

individual atoms, though fuzzy,

proving years of scientific theory, simulated here.

And not only can we see them--

with the tip of a powerful microscope,

we can actually move atoms

and begin to create amazing nano devices.

Some could one day patrol your body

for all kinds of diseases,

and clean out clogged arteries along the way.

Tiny chemical machines of the future

may even repair DNA.

One of the wildest things about the nano world,

substances here behave differently

than the same material does in our world.

To us, gold is golden in color.

But nano gold can be any color.

It absorbs light and generates heat,

leading to an idea:

injecting nano-sized gold particles

into the bloodstream...

which are chemically coded to attach to cancerous cells.

An incoming laser beam heats the gold particles...

burning the cells.

The promise of nano goes beyond medicine.

Another material with far different nano properties

is carbon,

the same breakable stuff found in pencil lead.

At the nano scale, it has mind-boggling strength.

With it, we've created the world's thinnest material,

graphene,

one carbon atom thick.

It's harder than diamonds

but nearly as flexible as rubber.

Turned into a roll, it's called a carbon nanotube,

one of the strongest and lightest materials on Earth.

With it, we could one day make things

we can only dream about today.

It may even be possible to use carbon nanotubes

to build an elevator to space.

We are on the threshold of extraordinary advances

born of our drive to see all that's hidden

in the world around us.

In una sera d'estate

sotto una pioggia infinita di polvere cosmica

l'aria piena di polline e scaglie di pelle

e pezzi di tutto sulla Terra....

le persone compiono le loro vite...

Buon compleanno ...Buon compleanno

Oh!

circondato dall'invisibile

Sapendo c'è molto di più intorno a noi di quanto possiamo vedere

cambia per sempre la nostra comprensione del mondo

Chissà cosa aspetta di essere visto..

Quali nuove meraviglie trasformeranno le nostre vite

Dovremo solo vedere
