Wouldn't it be great if we could be

Ali ne bi bilo krasno

invisible?

postati neviden?

Ha, right?

Kaj mislite?

I mean, we could spy on people without being noticed

Lahko bi neopazno vohunili za drugimi

and do whatever we want

in počeli, kar bi hoteli,

without being held responsible.

ne da bi nas kdo odkril.

Now, magicians have figured out

Čarodeji so ugotovili,

how to utilize full-sized mirrors to bend light

kako z ogledali upogniti svetlobo

in order to create disappearing illusions.

ter ustvariti iluzijo izginjanja.

Scientists have created metamaterials

Znanstveniki poznajo meta materiale,

to guide rays of light

ki svetlobne žarke vodijo

around tiny, two-dimensional objects.

okoli majcenih dvodimenzionalnih objektov.

Cameras can also film what is behind you

Kamere lahko posnamejo tisto za vami,

and project the image

so you appear invisible from the front.

usmerijo sliko

in vi boste od spredaj nevidni.

However, none of these options

A nobena od teh možnosti

can make an object as large as a person

ne more človeka narediti nevidnega

appear invisible for all angles and distances

z vseh strani in razdalj,

while its moving.

in to med premikanjem.

But if you are truly invisible,

A če bi bili res nevidni,

as in from within,

nevidni od znotraj,

here are a few problems

obstaja nekaj težav,

you may not have thought about before.

o katerih morda niste razmišljali.

To move around undetected by other people,

Da vas ne bi nihče opazil,

you would have to be totally naked.

bi morali biti povsem nagi.

Even if it's freezing outside!

Tudi če bi zmrzovalo!

You can't carry anything,

Ničesar ne bi mogli nositi,

including your wallet and keys,

niti denarnice in ključev,

otherwise people would just see

drugače bi ljudje videli

your wallet and keys floating around.

le letečo denarnico in ključe.

Drivers and people on the street can't see you either,

Vozniki in ljudje na cesti vas tudi ne bi videli,

therefore they can and will run into you at some point.

zato bi se lahko zaleteli v vas.

Oh, and you better not wear any perfume

In bolje, da ne nosite parfuma

or make any noise breathing,

in ne dihate naglas,

otherwise they'll know you're there.

drugače bodo vedeli, da ste tam.

And, just because you start off invisible,

In tudi če ste nevidni na začetku,

to ne pomeni, da boste taki ostali.

doesn't mean you'll stay that way.

What if someone accidentally spills

Kaj če vas kdo po nesreči

scolding hot coffee on you?

polije z vročo kavo?

And what if it rains?

In kaj če dežuje?

But if you think only liquid can make you visible,

In če mislite, da vas samo tekočina naredi vidne,

you're wrong.

se motite.

Dust consists of dead skin cells from humans,

Prah je sestavljen iz odmrlih celic kože,

soil particles,

and fibers from clothes made from cotton

delov prsti

ter vlaken bombažnih oblačil

and other materials.

in drugih materialov.

Dust sticks to the moisture on our skin when we sweat

Prah se prilepi na vlago kože, ko se potimo,

and the tiny hairs on our skin when we are dry.

in na dlačice na koži, ko smo suhi.

So, even if you are invisible,

Torej, tudi če ste nevidni,

dust would still land on every part of you.

bo prah pristal na vas.

We usually don't notice the dust on our skin

Ponavadi ga na koži ne opazimo,

because we can't see a thin layer of dust

ker se tanka plast prahu

on top of our skin color.

na koži ne vidi.

But, if you're invisible,

A če ste nevidni,

people would see a human-shaped blob of dust

bodo ljudje videli prah v obliki človeka,

walking around with extremely dirty soles.

ki hodi okoli z zelo umazanimi podplati.

Gross!

Fuj!

What do you think the world looks like

Kakšen je po vaše svet,

if you are invisible?

če ste nevidni?

Well, the answer is nothing.

Odgovor je: nikakršen.

The reason you can't see in the dark

Razlog, da ne vidimo v temi,

is because there is no light.

je pomanjkanje svetlobe.

To see an apple,

Da bi videli jabolko,

light has to hit the apple

ga mora ujeti svetloba

and return it to your eyes.

in se vrniti v naše oči.

Then, the retinas in your eyes

Potem očesna mrežnica

catch the light reflection for your brain

ujame ta odsev in možgani

to interpret into the image of an apple.

to razumejo kot sliko jabolka.

If you're invisible,

Če ste nevidni,

then, by definition, light would travel

bo svetloba potovala

through you or around you

skozi in okrog vas,

instead of bouncing off you for people to see.

ne bo se odbila od vas, da bi vas drugi videli.

But that means that retinas in your eyes

To pomeni, da vaša očesna mrežnica

are not catching the light, either.

tudi ne ujame svetlobe.

Therefore, your brain has nothing

Zato si možgani nimajo

to interpret into an image.

kaj razlagati v sliko.

Can you see your reflection

Lahko vidite svoj odsev

without a mirror to stop the light?

brez ogledala, ki ustavi svetlobo?

No.

Ne.

So, when you can't be seen by others,

Če vas torej drugi ne vidijo,

you also cannot see.

tudi vi ne vidite.

Ouch!

Av!

Now, have you given any thought

Ste kdaj pomislili,

as of whether the invisibility is permanent?

ali je nevidnost večna?

If it is, how can you receive medical treatment

Če je, kako vam bo zdravnik pomagal,

from a doctor if you're injured?

če ste ranjeni?

The doctor wouldn't know

Saj ne bo vedel,

where to apply ointments or bandages

kje namazati in obvezati,

because they cannot access your injury.

ker ne vidi vaše poškodbe.

For that matter, you can't see it either.

Tudi vi je seveda ne vidite.

I mean, what if you have an illness or an infection?

Kaj pa, če ste bolni ali imate vnetje?

How can the doctor diagnose you

Kako bo zdravnik to ugotovil,

without being able to see the color change or inflammation?

če ne vidi spremembe barve ali vnetja?

And what if everyone is permanently invisible?

In če bi bili vsi vedno nevidni?

Well, think about how boring the world would be

Kako dolgočasen bi bil svet,

če ne bi videli ljudi na ulici,

without seeing people on the streets,

on TV,

na televiziji,

or at home on your computer

doma na računalniku,

like right now.

tako kot zdaj?

It's lonely being invisible.

Biti neviden je samotno.
