00:12
An image is worth more than a thousand words,
0
12553
3842
Slika vredi više od hiljadu reči
00:16
so I'm going to start my talk
1
16395
2127
pa ću svoj govor početi
00:18
by stop talking and show you a few images
2
18522
2668
tako što ću prestati da pričam i pokazati vam nekoliko slika
00:21
that I recently captured.
3
21190
3167
koje sam skoro napravio.
00:42
So by now, my talk is already 6,000 words long,
4
42712
4030
Moj govor do sada već ima 6000 reči
00:46
and I feel like I should stop here.
5
46742
2148
i mislim da bi ovde trebalo da stanem.
00:48
(Laughter)
6
48890
2420
(Smeh)
00:51
At the same time, I probably owe you
7
51310
1821
U isto vreme, verovatno vam
00:53
some explanation
8
53131
1006
dugujem objašnjenje
00:54
about the images that you just saw.
9
54137
3103
u vezi sa slikama koje ste upravo videli.
00:57
What I am trying to do as a photographer,
10
57240
2723
Ono što pokušavam da uradim kao fotograf,
00:59
as an artist, is to bring the world
11
59963
2483
kao umetnik, je da spojim
01:02
of art and science together.
12
62446
3377
svet umetnosti i nauke.
01:05
Whether it is an image of a soap bubble
13
65823
2339
Bez obzira da li je to slika mehurića sapuna
01:08
captured at the very moment where it's bursting,
14
68162
2766
nastala istog trenutka kada on puca,
01:10
as you can see in this image,
15
70928
2472
kao što možete videti na ovoj slici,
01:13
whether it's a universe made of tiny little beads
16
73400
2608
bez obzira da li je to univerzum napravljen od sićušnih perli
01:16
of oil paint,
17
76008
2498
uljane boje,
01:18
strange liquids that behave in very peculiar ways,
18
78506
4343
čudnih tečnosti koje se ponašaju na specifične načine,
01:22
or paint that is modeled by centrifugal forces,
19
82849
4266
ili boje koja je oblikovana centrifugalnim silama,
01:27
I'm always trying to link those two fields together.
20
87115
3966
uvek pokušavam da povežem ove dve oblasti.
01:31
What I find very intriguing about those two
21
91081
2390
Ono što mi je interesantno u vezi sa ovim oblastima
01:33
is that they both look at the same thing:
22
93471
3279
je to da gledaju na istu stvar:
01:36
They are a response to their surroundings.
23
96750
2824
one su odgovori na svoju okolinu.
01:39
And yet, they do it in a very different way.
24
99574
3893
Ipak, to rade na veoma različite načine.
01:43
If you look at science on one hand,
25
103467
2047
Ako sa jedne strane pogledate nauku,
01:45
science is a very rational approach
26
105514
3423
ona ima veoma racionalan pristup
01:48
to its surroundings,
27
108937
1481
svom okruženju,
01:50
whereas art on the other hand
28
110418
2089
dok je sa druge strane umetnost
01:52
is usually an emotional approach to its surroundings.
29
112507
4303
obično emocionalni pristup svom okruženju.
01:56
What I am trying to do is I'm trying
30
116810
2017
Ono što pokušavam je
01:58
to bring those two views into one
31
118827
2641
da ova dva pogleda spojim u jedan
02:01
so that my images both speak to the viewer's heart
32
121468
3950
tako da moje slike govore srcu gledaoca,
02:05
but also to the viewer's brain.
33
125418
3194
ali i njegovom mozgu.
02:08
Let me demonstrate this based on three projects.
34
128612
4666
Dozvolite da demonstriram ovo na tri projekta.
02:13
The first one has to do with making sound visible.
35
133278
5054
Kod prvog se radi o tome da zvuk postane vidljiv.
02:18
Now as you may know,
36
138332
1018
Kao što možda znate,
02:19
sound travels in waves,
37
139350
2626
zvuk putuje preko talasa,
02:21
so if you have a speaker,
38
141976
2323
tako da ako imate zvučnik,
02:24
a speaker actually does nothing else
39
144299
2049
zvučnik zapravo ne radi ništa drugo
02:26
than taking the audio signal,
40
146348
1884
osim što uzima zvučni signal,
02:28
transform it into a vibration,
41
148232
3597
pretvara ga u vibraciju
02:31
which is then transported through the air,
42
151829
2701
koja se onda prenosi kroz vazduh,
02:34
is captured by our ear,
43
154530
1862
nju čuje naše uho,
02:36
and transformed into an audio signal again.
44
156392
3541
i onda se opet pretvara u zvučni signal.
02:39
Now I was thinking,
45
159933
1846
Ja sam razmišljao
02:41
how can I make those sound waves visible?
46
161779
4220
kako da te zvučne talase učinim vidljivim?
02:45
So I came up with the following setup.
47
165999
2116
Smislio sam sledeće rešenje.
02:48
I took a speaker, I placed a thin foil
48
168115
3720
Uzeo sam zvučnik i stavio tanku plastičnu foliju
02:51
of plastic on top of that speaker,
49
171835
2235
na vrh tog zvučnika
02:54
and then I added tiny little crystals
50
174070
2667
i onda sam dodao sićušne kristale
02:56
on top of that speaker.
51
176737
1977
na vrh tog zvučnika.
02:58
And now, if I would play a sound through that speaker,
52
178714
2900
Sada, kada bih preko tog zvučnika pustio neki zvuk,
03:01
it would cause the crystals to move up and down.
53
181614
3882
kristali bi se pomerali gore-dole.
03:05
Now this happens very fast,
54
185496
2299
Ovo se dešava jako brzo,
03:07
in the blink of an eye,
55
187795
1952
u deliću sekunde,
03:09
so, together with LG, we captured this motion
56
189747
3687
pa smo zajedno sa LG-em uhvatili ovaj pokret
03:13
with a camera that is able
57
193434
1686
fotoaparatom koji može
03:15
to capture more than 3,000 frames per second.
58
195120
3475
da snimi više od 3000 kadrova po sekundi.
03:18
Let me show you what this looks like.
59
198595
3473
Da vam pokažem kako ovo izgleda.
03:22
(Music: "Teardrop" by Massive Attack)
60
202068
5367
(Muzika: "Teardrop" izvođača Massive Attack)
04:03
(Applause)
61
243406
5318
(Aplauz)
04:08
Thank you very much.
62
248724
1263
Hvala vam mnogo.
04:09
I agree, it looks pretty amazing.
63
249987
3244
Slažem se, izgleda neverovatno.
04:13
But I have to tell you a funny story.
64
253231
2359
Ali moram da vam ispričam jednu smešnu priču.
04:15
I got an indoor sunburn doing this
65
255590
2514
Radeći ovo, dobio sam opekotine u zatvorenom prostoru
04:18
while shooting in Los Angeles.
66
258104
2048
dok sam snimao u Los Anđelesu.
04:20
Now in Los Angeles, you could get a decent sunburn
67
260152
2275
U Los Anđelesu možete dobro izgoreti
04:22
just on any of the beaches,
68
262427
1726
na bilo kojoj plaži,
04:24
but I got mine indoors,
69
264153
2070
ali ja sam izgoreo unutra,
04:26
and what happened is that,
70
266223
1709
a desilo se sledeće:
04:27
if you're shooting at 3,000 frames per second,
71
267932
2821
ako snimate na 3000 kadrova po sekundi,
04:30
you need to have a silly amount of light, lots of lights.
72
270753
4489
morate da imate neverovatnu količinu svetla.
04:35
So we had this speaker set up,
73
275242
2529
Podesili smo ovaj zvučnik
04:37
and we had the camera facing it,
74
277771
1599
i ka njemu okrenuli fotoaparat,
04:39
and lots of lights pointing at the speaker,
75
279370
3386
i dosta svetla je bilo upereno na zvučnik,
04:42
and I would set up the speaker,
76
282756
1355
ja bih zvučnik podesio,
04:44
put the tiny little crystals on top of that speaker,
77
284111
3046
stavio bih na njega sićušne kristale
04:47
and we would do this over and over again,
78
287157
2821
i ovo bismo stalno ponavljali
04:49
and it was until midday that I realized
79
289978
2761
i tek oko podneva sam shvatio
04:52
that I had a completely red face
80
292739
2337
da mi je lice bilo potpuno crveno
04:55
because of the lights pointing at the speaker.
81
295076
3086
zbog svetala uperenih ka zvučniku.
04:58
What was so funny about it was that
82
298162
2306
Ono što je smešno
05:00
the speaker was only coming from the right side,
83
300468
2727
je da je zvučnik bio okrenut samo na desnu stranu
05:03
so the right side of my face was completely red
84
303195
3367
tako da je desna strana mog lica bila potpuno crvena
05:06
and I looked like the Phantom of the Opera
85
306562
1842
i ostatak nedelje sam izgledao
05:08
for the rest of the week.
86
308404
2842
kao Fantom iz opere.
05:11
Let me now turn to another project
87
311246
2103
Hajde da pogledamo drugi projekat
05:13
which involves less harmful substances.
88
313349
3520
sa manje opasnim supstancama.
05:19
Has anyone of you heard of ferrofluid?
89
319852
3640
Da li je neko od vas čuo za feromagnetne tečnosti?
05:23
Ah, some of you have. Excellent.
90
323492
2522
Neki jesu. Odlično.
05:26
Should I skip that part?
91
326014
1877
Da li treba da preskočim taj deo?
05:27
(Laughter)
92
327891
1582
(Smeh)
05:29
Ferrofluid has a very strange behavior.
93
329473
3263
Feromagnetna tečnost se ponaša veoma čudno.
05:32
It's a liquid that is completely black.
94
332736
2252
To je potpuno crna tečnost.
05:34
It's got an oily consistency.
95
334988
2494
Ima gustinu poput ulja.
05:37
And it's got tiny little particles of metal in it,
96
337482
3460
U sebi ima sitne čestice metala,
05:40
which makes it magnetic.
97
340942
2139
zbog čega je namagnetisana.
05:43
So if I now put this liquid into a magnetic field,
98
343081
3553
Ako ovu tečnost stavim u magnetno polje,
05:46
it would change its appearance.
99
346634
2793
ona će promeniti izgled.
05:49
Now I've got a live demonstration over here
100
349427
3795
Sada ću vam demonstrirati ovo
05:53
to show this to you.
101
353222
2576
uživo.
05:59
So I've got a camera pointing down at this plate,
102
359533
2953
Fotoaparat je uperen na ovu ploču,
06:02
and underneath that plate, there is a magnet.
103
362486
3528
a ispod nje se nalazi magnet.
06:06
Now I'm going to add some of that ferrofluid
104
366014
2992
Sada ću na magnet dodati
06:09
to that magnet.
105
369006
3304
malo te tečnosti.
06:17
Let's just slightly move it to the right
106
377609
4129
Da ga samo malo pomerimo nadesno
06:25
and maybe focus it a little bit more. Excellent.
107
385330
4758
i možda da još malo fokusiramo. Odlično.
06:30
So what you can see now is that
108
390088
2193
Sada možete videti
06:32
the ferrofluid has formed spikes.
109
392281
2397
da je tečnost oformila bodlje.
06:34
This is due to the attraction and the repulsion
110
394678
3353
Ovo se dešava zbog privlačenja i odbijanja
06:38
of the individual particles inside the liquid.
111
398031
3709
pojedinačnih čestica unutar tečnosti.
06:41
Now this looks already quite interesting,
112
401740
2243
Ovo već sada izgleda prilično zanimljivo,
06:43
but let me now add some watercolors to it.
113
403983
3554
ali hajde da dodamo malo vodenih boja u ovo.
06:47
Those are just standard watercolors
114
407537
2454
Ovo su samo obične vodene boje
06:49
that you would paint with.
115
409991
1631
sa kojima biste i slikali.
06:51
You wouldn't paint with syringes,
116
411622
1343
Ne biste slikali špricevima,
06:52
but it works just the same.
117
412965
4988
ali princip je isti.
07:10
So what happened now is,
118
430798
2112
Ono što se desilo je sledeće:
07:12
when the watercolor was flowing into the structure,
119
432910
3244
kada se vodena boja ulila u strukturu,
07:16
the watercolors do not mix with the ferrofluid.
120
436154
3351
boje se nisu pomešale sa feromagnetnom tečnošću.
07:19
That's because the ferrofluid itself
121
439505
2336
To je zbog toga što je sama tečnost
07:21
is hydrophobic.
122
441841
2183
hidrofobna.
07:24
That means it doesn't mix with the water.
123
444024
2163
To znači da se ne meša sa vodom.
07:26
And at the same time, it tries to maintain its position
124
446187
3009
U isto vreme pokušava da održi svoj položaj
07:29
above the magnet,
125
449196
1365
iznad magneta
07:30
and therefore, it creates those amazing-looking
126
450561
3395
i tako stvara te neverovatne
07:33
structures of channels and tiny little ponds
127
453956
3333
strukture kanala i barice
07:37
of colorful water paint.
128
457289
2580
šarenih vodenih boja.
07:39
So that was the second project.
129
459869
1751
To je bio drugi projekat.
07:41
Let me now turn to the last project,
130
461620
2352
Hajde sada da se osvrnemo na poslednji projekat,
07:43
which involves
131
463972
4772
koji uključuje
07:48
the national beverage of Scotland.
132
468744
2090
nacionalno piće Škotske.
07:50
(Laughter)
133
470834
2320
(Smeh)
07:53
This image, and also this one,
134
473154
3920
Ova slika, a takođe i ova,
07:57
were made using whiskey.
135
477074
3271
napravljene su pomoću viskija.
08:00
Now you might ask yourself,
136
480345
1490
Možda ćete se zapitati,
08:01
how did he do that?
137
481835
1028
kako je to uradio?
08:02
Did he drink half a bottle of whiskey
138
482863
1849
Da li je popio pola boce viskija
08:04
and then draw the hallucination he got
139
484712
2711
i onda naslikao na papiru
08:07
from being drunk onto paper?
140
487423
3614
svoju pijanu halucinaciju?
08:11
I can assure you I was fully conscious
141
491037
2244
Uveravam vas da sam bio potpuno svestan
08:13
while I was taking those pictures.
142
493281
3110
dok sam fotografisao ovo.
08:16
Now, whiskey contains 40 percent of alcohol,
143
496391
4102
Viski sadrži 40% alkohola,
08:20
and alcohol has got some very interesting properties.
144
500493
4236
a alkohol ima neka veoma zanimljiva svojstva.
08:24
Maybe you have experienced
145
504729
1691
Možda ste već iskusili
08:26
some of those properties before,
146
506420
2126
neka od tih svojstava,
08:28
but I am talking about the physical properties,
147
508546
2719
ali ja pričam o fizičkim svojstvima,
08:31
not the other ones.
148
511265
2235
a ne o onim drugim.
08:33
So when I open the bottle, the alcohol molecules
149
513500
4200
Kada otvorim flašu, molekuli alkohola
08:37
would spread in the air,
150
517700
1343
se šire vazduhom
08:39
and that's because alcohol is a very volatile substance.
151
519043
4080
zato što je alkohol veoma nestalna supstanca.
08:43
And at the same time, alcohol is highly flammable.
152
523123
4687
I u isto vreme, veoma je zapaljiv.
08:47
And it was with those two properties
153
527810
2149
Koristeći ta dva svojstva
08:49
that I was able to create the images
154
529959
2605
mogao sam da stvorim slike
08:52
that you're seeing right now.
155
532564
2030
koje sada gledate.
08:54
Let me demonstrate this over here.
156
534594
3471
Dozvolite da to demonstriram ovde.
09:04
And what I have here is an empty glass vessel.
157
544709
3318
Ovde imam prazan stakleni sud.
09:08
It's got nothing in it.
158
548027
1309
U njemu nema ničega.
09:09
And now I'm going to fill it with oxygen
159
549336
3808
Sada ću ga napuniti kiseonikom
09:13
and whiskey.
160
553144
2681
i viskijem.
09:31
Add some more.
161
571962
2953
I još malo.
09:38
Now we just wait for a few seconds
162
578171
2015
Sada samo čekamo nekoliko sekundi
09:40
for the molecules to spread inside the bottle.
163
580186
3047
da se molekuli rašire unutar flaše.
09:43
And now, let's set that on fire.
164
583233
2397
Hajde da to sada zapalimo.
09:45
(Laughter)
165
585630
4710
(Smeh)
10:03
So that's all that happens.
166
603740
1538
To je sve što se dešava.
10:05
It goes really fast, and it's not that impressive.
167
605278
3199
Kreće se veoma brzo i nije tako impresivno.
10:08
I could do it again to show it one more time,
168
608477
2606
Mogao bih da to uradim opet da pokažem ovo još jednom,
10:11
but some would argue that this is a complete waste
169
611083
2731
ali neki bi rekli da je to apsolutno traćenje viskija
10:13
of the whiskey, and that I should rather drink it.
170
613814
3852
i da bi bolje bilo da ga popijem.
10:17
But let me show you a slow motion
171
617666
2088
Ali hajde da vam pokažem usporeni snimak
10:19
in a completely darkened room
172
619754
1695
ovoga što sam vam pokazao uživo,
10:21
of what I just showed you in this live demonstration.
173
621449
5250
u potpuno zatamnjenoj prostoriji.
10:33
So what happened is that the flame
174
633605
2733
Desilo se to da je plamen
10:36
traveled through the glass vessel from top to bottom,
175
636338
3992
prošao kroz stakleni sud od vrha nadole,
10:40
burning the mix of the air molecules
176
640330
3049
paleći mešavinu molekula vazduha
10:43
and the alcohol.
177
643379
1829
i alkohola.
10:45
So the images that you saw at the beginning,
178
645208
2816
Slike koje ste videli na početku,
10:48
they are actually a flame stopped in time
179
648024
4344
zapravo su plamen zaustavljen u vremenu
10:52
while it is traveling through the bottle,
180
652368
2478
dok putuje kroz bocu
10:54
and you have to imagine
181
654846
1218
i morate zamisliti
10:56
it was flipped around 180 degrees.
182
656064
3466
da je zaokrenut za 180 stepeni.
10:59
So that's how those images were made.
183
659530
2438
Tako su nastale te slike.
11:01
(Applause)
184
661968
4356
(Aplauz)
11:06
Thank you.
185
666324
2773
Hvala vam.
11:09
So, I have now showed you three projects,
186
669097
3083
Sada sam vam pokazao tri projekta
11:12
and you might ask yourself, what is it good for?
187
672180
2652
i možda ćete se zapitati, čemu služi sve ovo?
11:14
What's the idea behind it?
188
674832
1591
Koja je ideja iza toga?
11:16
Is it just a waste of whiskey?
189
676423
1333
Da li je to samo bacanje viskija?
11:17
Is it just some strange materials?
190
677756
4225
Da li su to samo neki čudni materijali?
11:21
Those three projects, they're based on very simple
191
681981
2813
Ta tri projekta zasnovana su na veoma jednostavnim
11:24
scientific phenomena,
192
684794
1662
naučnim pojavama
11:26
such as magnetism, the sound waves,
193
686456
2741
poput magnetizma, zvučnih talasa,
11:29
or over here, the physical properties of a substance,
194
689197
4042
ili u ovom slučaju fizičkih svojstava supstance,
11:33
and what I'm trying to do
195
693239
1912
i ono što pokušavam da uradim je
11:35
is I'm trying to use these phenomena
196
695151
3149
da iskoristim ove pojave
11:38
and show them in a poetic and unseen way,
197
698300
3117
i da ih prikažem na poetski i do sada neviđen način
11:41
and therefore invite the viewer
198
701417
2419
i tako apelujem na gledaoca
11:43
to pause for a moment
199
703836
1900
da zastane na trenutak
11:45
and think about all the beauty
200
705736
2715
i pomisli na svu lepotu
11:48
that is constantly surrounding us.
201
708451
3943
koja nas stalno okružuje.
11:52
Thank you very much.
202
712394
1429
Hvala vam mnogo.
11:53
(Applause)
