English: 
Infrared radiation
is a radiation with wavelengths
from 350 nanometers to 3 milimeters.
That is one way to say it.
You can also say it a bit differently.
For this, I'll be needing
one of the favorite
house appliances - a remote control
which I kidnapped
from my house today.
I hope they won't mind.
Here it is, a standard remote control.
We all know the remote
has this light on the front.

Infracrveno zračenje
je elektromagnetno značenje
talasnih dužina od 350 nanometara
do 3 milimetra.
Može to i tako da se kaže, naravno.
Može to da se kaže i malko drugačije.
Za ovo će mi trebati
jedan omiljeni kućni uređaj,
daljinski upravljač,
koji sam kidnapovala danas od kuće.
Valjda mi neće zameriti.
Evo ga najobičniji daljinski.
Svi smo videli da daljinski
ima napred neku lampicu.
Meni je uvek izgledalo da ta lampica
malo ne radi.

Serbian: 
Stisnete bilo šta, ništa se ne dešava.
Ali ova lampica ima svoju svrhu tu,
radi očigledno.
Samo treba da nađemo pravi način
kako da je pogledamo.
A za to mi treba
jedan dobrovoljac iz publike,
neko ko kod sebe ima
mobilni telefon sa kamerom.
Bilo ko. Ništa strašno.
Može. Evo dobrovoljac.
Super. Dobrovoljac, Vaše ime je?
Momak: Jovan.
Tijana: Jovan, e fino Jovane.
Hvala, uveri se nema laži, nema prevare.
Običan daljinski.
Stisni bilo šta, ništa ne svetli.
Hajde sad upali kameru.
Samo malo da se uključi.
Nauci nekad treba malo vremena.
Nije to sve tako odmah nešto da se desi.
Već treba da pustimo nauku,
telefone da prorade.
Je l' radi?
Jovan: Radi.
Evo radi kamera. 
Hajd' sad pogledaj ovu lampicu
kroz kameru.
Je l' vidiš sad nešto? Šta vidiš?
Jovan: Uključi se svetlo.
TP: Svetlo se uključi.

English: 
To me it always seemed 
as if that light didn't work -
you can press any button,
but nothing happens.
But this light has a purpose,
it works obviously.
We just need the right way to look at it.
And for that I'll be needing
a volunteer, from the audience.
Someone who has a mobile phone
with a camera.
Anyone, it's nothing hard.
Here's a volunteer. Great.
Your name is?
Guy: Jovan.
Tijana: Jovan, okay, Jovan.
Here, see for yourself, it's no trick
- just a standard remote.
Press anything, it's not glowing.
Now turn on the camera.
Just wait until it's turns on,
well science sometimes needs
time, you know.
It can't happen instantly,
you have to let science
and phones to start working.
Is it working?
Jovan: It is.
The camera works.
Try now, look at this light
through your camera.
Can you see it?
Do you see something now?
What do you see?
Jovan: The light is on.
Tijana: The light is on!

English: 
Now letćs others see
that this is no trick.
You can see the light.
Can we get a camera?
We can.
Right, I need to change the slide.
Let's see.
Can everyone see?
Good, you can.
Can you see with me standing here?
Can everyone see?
A light?
That's the infrared light. 
That which you've seen.
That light is invisible to our naked eye.
Thank you very much.
Tell everyone to try this at home.
The light which is invisible
for our naked eye,
but thanks to science we can see it
with the help
of any kind of digital camera,
the thing you have in your
ordinary mobile phones.
That's because there is a small CCD chip,
that's what it's called,
which we have today,
and which we use thanks to science.
The astronomers wanted
to make better pictures of the sky
and to give us such great pictures
like those of space
that the Hubble telescope gives us.
All that with the help
of a CCD chip which,

Serbian: 
Hajde sad da vide svi ostali
da nema laži, nema prevare.
Vidi se svetlo.
Je l' možemo da dobijemo kameru?
Možemo.
Aha, treba da promenim slajd.
Vidimo.
Je l' se vidimo? Vidimo se.
Dobro. I je l' vidite od mene nešto?
Je l' vide svi svetlo?
To je infra-crveno svetlo.
To što ste videli.
Svetlost koja je nevidljiva za naše oko.
Hvala, hvala puno.
Reci svima da probaju ovo kod kuće.
Svetlost koja je nevidljiva
za naše golo oko,
ali, zahvaljujući nauci, danas možemo
da je vidimo
pomoću bilo kog digitalnog foto-aparata,
digitalne kamere.
Znači ono što imate
u vašim telefonima najobičnijim.
Zato što u svemu tome
ima jedan mali CCD čip,
koji imamo danas i koristimo
zahvaljujući nauci.
Samo što su uglavnom astronomi želeli
mnogo lepše da slikaju to nebo
i da nam daju tako sjajne slike
kao Habl teleskop,
koji nam daje slike svemira.
Sve to uz pomoć tog CCD čipa koji,

Serbian: 
osim vidljivog vidi i ono
što je za naše oko nevidljivo.
Ali interesantna je generalno priča
kako su ljudi uopšte otkrili
infra-crvenu svetlost.
Vidimo ovde naučnika jednog.
Vilijem Heršel se zvao.
On je uzeo jednu prizmu
i razložio svetlost na dugu.
Kod kuće, napravio svoju malu kućnu dugu.
I onda je želeo u stvari da izmeri
temperaturu boje,
da li svaka boja ima istu temperaturu.
Mislim, što bi imala?
Uzeo je po jedan termometar
i stavio u svaku od boja
i merio temperaturu.
Iznenadio se kada je video
da je temperatura različita
i da čak raste od plave ka crvenoj.
Da crvena pokazuje
najveću temperaturu.
Topliju nego što je njegov
sobni termometar pokazivao.
Ali je onda otišao korak dalje.
Uradio je nešto luđe.
Uzeo je još jedan termometar
i stavio ga tamo gde nema ništa.
Pored crvene boje.
Izmerio je još veću temperaturu.

English: 
besides the visible sees things 
that are invisible to our naked eye.
But the story of how people 
discovered infrared light
is interesting.
Here we have a scientist,
William Herschel was his name.
He took a prism and resolved
light into a rainbow.
At his home, he made his own
little house rainbow.
And then he actually wanted
to measure the temperature of color,
to see whether or not
every color had the same temperature.
I mean, why would it?
He took a pan thermometer
and placed it in each of the colors
and measured the temperature.
He was surprised when he saw
different temperatures, that it 
actually grew from blue towards red.
The red showed the highest temperature.
Warmer than his thermometer was showing.
But then he went a step further.
He did something even crazier.
He took another thermometer
and placed it where there's nothing. 
Next to the red color.
He measured even higher temperature.

English: 
Higher than his room temperature
and he realized that it's not correct
that there's nothing there.
There is something,
but our eye can't see it.
But definitely something
exists there and that something
is the infrared light we recognize today.
I don't know how this story affects you,
but this story about infrared light
excites me.
It has all the elements
which got me into science,
astronomy.
Many people see science
as something useful,
but also as something boring.
What's so interesting about it?
That remote control is useful
but we don't get too excited
about it, except when it disappears.
I see science a bit differently.
As something useful,
but as something totally cool and fun.
I see that remote as something 
that makes the infrared light
and then I can use my phone
to look at it and show it to the kids,
doesn't really matter.
But as something totally cool and fun.

Serbian: 
Temperaturu veću od
njegove sobne temperature
i zaključio da nije tačno
da tu nema ništa.
Tu ima nešto,
samo što ga naše oko ne vidi.
Ali tu definitivno ima nešto
i to nešto je ta infra-crvena svetlost
koju mi danas prepoznajemo.
Ne znam kako ova priča utiče na vas,
ova priča generalno
o infra-crvenoj svetlosti
me potpuno oduševljava.
Sadrži sve one elemente
zbog kojih se ja bavim naukom,
astronomijom.
Mnogi vide nauku kao nešto korisno
ali kao nešto dosadno.
Šta sad tu ima da se radi?
Taj daljinski je koristan
ali ne uzbuđujemo se previše
osim kad nestane.
Ja vidim nauku malo drugačije.
Kao korisno ali kao nešto
totalno kul i zabavno.
Vidm taj daljinski
kao nešto što pravi
tu infra-crvenu svetlost
i onda mogu telefonom to da gledam
i pokazujem klincima, nije bitno.
Ali skroz kao nešto kul i zabavno.

Serbian: 
S druge strane, taj ceo proces
kako su otkrili tu infra-crvenu svetlost
pokazuje tu najbolju stvar nauke,
a to je da morate da izađete iz okvira.
Možete da pretpostavite šta god hoćete,
da uradite
nešto najluđe što niko nije uradio.
Tako dolazite do tih naučnih otkrića.
I to je po meni sjajno.
I zbog toga jednostavno obožavam nauku,
što je super jer... radim puno.
Radim svaki dan, ceo dan.
Idem na posao, ali nemam nikad osjećaj
kao da idem na posao.
Više imam osjećaj
kao da idem da se zezam.
Jer imate loših dana
kada vam nije ni do čega.
"Pa, gde ću sad da idem na posao?
Jao, majko moja."
Ustanem, odem i ne osećam kao da je posao.
Mnogo lakše prelazim te neke prepreke
zato što baš uživam u tome
i mnogo lakše sam presedela kroz gomilu
nekih dosadnih predavanja,
koja sam pokušala
na početku da vam dočaram.
Jer na fakultetu se onako potpuno smorite.

English: 
On the other hand, the entire process
of how the infrared light was discovered
shows the best thing about science,
where you have to think
outside of the box.
You can guess anything you want,
do something insane,
which no one's done before.
That's how you get
to scientific discoveries.
I find it great.
And for that I simply love science,
which is great since... I work a lot.
I work every day, through the entire day.
I go to work but it doesn't feel like
I'm going to work.
It feels more like fooling around
rather than working.
There are bad days when you
feel like doing nothing.
"Do I have to go to work?
Oh, sweet mother of mine."
I get up in the morning
and it doesn't feel like work.
I tackle these obstacles because
I really enjoy it and it helped me
to sit through a bunch of boring classes
in college,
which I tried to demonstrate
at the begining.
Because you get completely 
bored at college.

English: 
I know I love this, I'll make it
and it will be something fun.
But I was fortunate enough
to realize what it is that I love,
that makes me so interested.
It all started out of something, 
seemingly, totally trivial.
Actually, it started out from a cartoon.
I didn't know its title.
Just recently I found out
that it was "Horton Hears a Who".
Anyway, I was watching this cartoon
where an elephant walks across a meadow.
He hears something.
He hears voices in a flower.
It turns out there's a whole world
of little people in that flower,
unaware of the existence
of any other world.
And there my light bulb flashed
for the first time,
and raised a certain interest.
Wait a minute!
How do we know that our universe
doesn't exist within another world,
and that there isn't an elephant
listening to us?
That's the point where my interest
in astronomy started off.

Serbian: 
Znam da ovo volim, 'ajde izdržaću ovo,
biće to nešto zabavno.
Ali u principu ja jesam imala neku sreću
da skapiram dosta rano šta je to
što toliko volim, što me toliko interesuje.
I to je počelo od nečeg,
naizgled, totalno trivijalnog.
U stvari, počelo je od crtanog filma.
Nisam znala kako se to zove.
Tek nedavno sam saznala da se taj
crtani film zvao "Horton Hears a Who".
Uglavnom, gledala sam neki crtani film
gde ide neki slon livadom. Čuje nešto.
I ispostavlja se da u nekom cvetu
čuje neke glasove.
Ispostavlja se da u tom cvetu
živi čitav jedan svet malih ljudi
koji ne znaju
da postoji išta više izvan njih.
I tu se ta moja neka lampica
prvi put upalila, to neko interesovanje.
Čekaj, čekaj.
Kako mi da znamo da ovaj naš svemir
u kome živimo,
znači mi u tom nekom svetu, izvan nas
postoji neki slon koji nas prisluškuje?
Znači tu je negde to moje interesovanje
za astronomiju krenulo.

Serbian: 
Ali poenta ove priče je da, generalno,
nekad nešto zaista najobičnije
može da vas toliko zainteresuje
i da vam pokaže šta je to
što toliko volite, u čemu toliko uživate.
Opet, s druge strane znam da na kraju
odlučiti da se bavite onim što volite
nije uvek lako.
Ja kad sam trebala da upišem astrofiziku,
nije bilo trivijalno.
Tu su pritisci roditelja,
okoline, društva,
vremena u kome živimo.
Kad sam ja upisivala bila su teška vremena
i moji roditelji su rekli:
"Jao lepo dete što ti to voliš,
tu astronomiju, baš je to lepo.
Ali hajde možda nešto,
neko programiranje.
Nećeš imati hleba da jedeš."
I ja sam razmislila dosta
o njihovom predlogu
i na kraju sam se ipak odlučila da
ipak studiram tu astrofiziku, astronomiju
iz prostog razloga što...
mislim ok je to programiranje.
Možda bih ja bila dobar programer.
Mislim i sad radim programiranje.
Ali znam sigurno da ne bih bila najbolji
programer koji mogu da budem.

English: 
But the point of this story is
that sometimes the most unusual things
can occupy you and show
what it is that you love and enjoy.
On the other hand, it's not always easy 
to decide to do something you love.
It wasn't trivial when I was supposed
to start studying astrophysics.
There was the parental pressure,
the pressure of the society
an the pressure of the time we live in.
When I was getting into college
my parents told me,
"You seem to like astrophysics so much
and that's very nice.
But you sholud try programming
or something like that.
You will hardly survive!"
And I considered 
their proposal for a long time
and decided to study astrophysics
and astronomy neverthless
simply because...
I mean programing is okay.
Maybe I would be a great programmer.
I mean, I do programming now.
But I certainly know I wouldn't be 
the best programmer.

Serbian: 
Mene to ne interesuje dovoljno,
ne uzbuđujem se previše oko toga.
Bilo bi ok, ali znam da nikada ne bih
mogla da dam 100% od sebe kod toga.
Ali šta je još jedna bitna stvar?
Mislim, kod mene je to nauka.
To sad zvuči: "Uuuu ti si naučnik.
Strašno!"
Ali ne mora to biti ništa grandiozno,
to nešto što volite da radite.
Jedan čovek me potpuno uverio u to.
Zvali smo ga Ćale.
I radio je u kiosku, prodavao je
pljeskavice pored Fizičkog fakulteta
dok sam ja studirala.
I zanimljivo je bilo da je on pričao
o tim pljeskavicama uvek
kao da pravi neko epohalno umetničko delo.
I onda kad bismo hteli da od priloga
stavimo kečap ili senf ili nešto tako jako
on bi nas uvek izgrdio i rekao:
"Ne, ne, ne. Ne može."
To kvari savršen ukus mesa
koje on pokušava da napravi.
I tu sam ja zaista shvatila
da taj čovek...
Neko će reći: "Ha, šta on radi?
Prodaje pljeskavice."
Čovek je zadovoljan, srećan.
Čovek jednostavno uživa u tome,
voli da napravi tu savršenu, za njega,

English: 
I don't find it interesting enough,
I don't get too excited about it.
I would be okay, but I know
I could never put my 100% in it.
But what is the other important issue?
I mean, for me it is science.
I know that sounds like,
"Ooh, you're a scientist. Scary!"
But it doesn't have to be grandiose,
that thing you love to do.
One man completely assured me in that.
We called him Pops.
And he was selling burgers at a food stand
near the Faculty of Physics
while I went to college.
The interesting thing was that he talked
about those burgers like he was
creating some epic work of art.
Whenever we wanted to put ketchup
or mustard on the burger
he gave us hard time,
"No, no, no. Don't do that"
Since it spoils the perfect taste of meat
he's trying to make.
And there I realized that that man...
Someone would say,
"He just sells burgers."
The man is satisfied, happy.
The man simply enjoys making
that perfect burger, according to him,

English: 
and he is content.
And that's okay.
So it's okay to do something,
although someone would say it is trivial,
as long as you enjoy it.
If my science career hadn't worked out,
I would probably be a singer.
I wouldn't be great at it, but I enjoy it
since it's my second favorite
thing to do.
Lastly, what is 
the important thing to say?
You don't have to be the best in the world
in what you do.
All of you know that I'm no Einstein.
Believe me, I know I'm no Einstein.
Also, as a scientist,
I'm very far from Steven Hawking.
You've probably heard of Stiven Hawking.
But I'll tell you that, as a scientist, 
I'm very far from Dave Schramm,
of whom none of you have heard,
but he was the most famous in the area
I'm dealing with now.
In comparison to him,
I'm around somewhere here.
But that's okay, because I know
I'm not the best scientist in the world
but I know
I'm the best scientist I can be.

Serbian: 
pljeskavicu i on je bio zadovoljan.
I to je ok.
Znači ok je da radite nešto,
neko vam može reći da je to trivijalno,
ali je ok dok vi uživate u tome.
Ja, da mi ova nauka nije uspela,
bih verovatno otišla u pevačice.
Nije ni da bih tu briljirala nešto,
uživam u tome jer mi je to
druga omiljena stvar da radim.
I na kraju šta je bitno reći?
Ne morate biti najbolji na svetu
u tome što radite.
Vi sigurno u sobi znate
da ja nisam Ajnštajn.
Verujte mi, ja znam da nisam Ajnštajn.
Takođe verujte mi da sam daleko
kao naučnik, od Stivena Hokinga.
Verovatno ste čuli za Stivena Hokinga.
Ali reći ću vam da znam sam kao naučnik
daleko, verovatno, i od Dejva Šrema
za koga niko od vas nije čuo ali je bio
najveća faca u oblasti kojom se ja bavim.
Znači ja sam naspram njega tako negde.
Ali to je ok, jer ja znam da nisam
najbolji naučnik na svetu u tome
ali znam sam najbolji naučnik
koji ja mogu da budem.
Ja radim to što ja volim i znam da
dajem tu maksimum, sve od sebe

Serbian: 
i možda nisam najbolji naučnik na svetu
ali znam da sam najbolja ja u tome
koja mogu da budem i to je zato ok.
Tako da ako već znate šta je to nešto
što vas toliko pokreće,
uzmite i radite to.
Nemojte se bojati toga,
kao: "To je bez veze. To je trivijalno.
Šta ćeš, od čega ćeš živeti?"
Radite to jer u njemu možete biti
najbolji vi.
Ako nemate još uvek to nešto, nađite ga.
Može biti u nečemu trivijalnom.
Kao crtani film,
može da vas dovede do toga.
Dakle, nađite to nešto što vas tako
pokreće da želite da date sve više i više.
Za mene je to nauka.
Ta totalno kul nauka zbog koje možemo
ovo da vidimo, ovakve nevidljive stvari.
Hvala.
(Aplauz)

English: 
Since I love what I do and I know
I'm pushing myself to the limits
and perhaps I'm not the best scientist
in the world but I do know
I'm the best I can be at it
and because of that it's okay.
So if you already know what is it
that drives you that much,
be brave and do it.
Don't be afraid of it, like,
"That's lame. It's so trivial.
What will you do?
How will you make a living?"
Do it because you can be the best you.
If you still don't have
that something, find it.
It can be in something trivial.
Like the cartoon, 
it can lead you to it.
So find something that motivates you
so much that it makes you
try harder and harder.
For me it is science.
Totally cool science which enables us
to see these invisible things.
Thank you.
(Applause)
