By day, I'm a venture capitalist.

Po danu ja sam ulagač u nove poslovne poduhvate. Tijekom vikenda, volim rakete.
00:20
On weekends, I love rockets.
1
20489
1547
Volim fotografiju, volim rakete,
00:22
I love photography, I love rockets.

00:23
I'm going to talk about a hobby that can scale
3
23833
2158
i pričat ću vam o hobiju koji može narasti
i pokazati vam neke fotografije koje sam snimio tijekom godina
00:26
and show you photos I've taken over the years
4
26015
2108
s djecom kao što su ova, djeca koja će, nadam se, odrasti i zavoljeti modeliranje raketa,
00:28
with kids like these, that hopefully will grow up to love rocketry
5

i naposljetku možda postati idući Richard Branson ili Diamandis.
00:31
and eventually become a Richard Branson or Diamandis.

My son designed a rocket that became stable, a golf ball rocket.
7
33798
3009
Moj sin je dizajnirao raketu koja je postala stabilna --
raketu loptice za golf. Mislio sam kako je to poprilično zanimljiv eksperiment
00:36
I thought it was quite an interesting experiment
8
36831
2253
prema načelima raketne znanosti,
00:39
in the principles of rocket science.
9

i leti ravno poput strijele.
00:40
And it flies straight as an arrow.
10

00:42
Baking soda and vinegar.
11
42624
1353
Soda i ocat.
00:44
Night shots are beautiful,
12
44001
1310
Noćne snimke su prekrasne,
00:45
piercing the Big Dipper and the Milky Way.
13

prodoran Veliki medvjed i Mliječna staza.
00:48
2-stage rockets with video cameras on them,
14
48886
2199
Dvorazinske rakete, rakete s video kamerama na njima,
s ugrađenim računalima koja bilježe njihove letove.
00:51
onboard computers logging their flights, rocket gliders that fly back to Earth.
15
51109
3778
Raketne jedrilice koje lete natrag na zemlju.
00:54
I use RockSim to simulate flights before they go
16
54911
2243
Koristim RockSim kako bih simulirao letove prije nego odu
da vidim hoće li probiti zvučni zid ili ne,
00:57
to see if they'll break supersonic,
17
57178
1675
00:58
then fly them with onboard computers to verify performance.
18
58877
2821
i zatim ih lansiram s ugrađenim računalima kako bih provjerio njihovu izvedbu.
01:01
To launch the big stuff, you go to the middle of nowhere:
19
61722
2677
Ali lansirati doista velike stvari, ići usred ničega --
Black Rock pustinja, gdje se opasne stvari događaju.
01:04
Black Rock Desert, where dangerous things happen.
20
64423
2335
I dečki postaju veći, i rakete postaju veće.
01:06
The boys and the rockets get bigger.
21
66782
1739
I koriste motore
01:08
They use motors used on cruise-missile boosters.
22
68545
2611
koje doslovno upotrebljavaju za krstarenje projektilnih potisnika.
01:11
They rumble the belly and leave even photographers in awe,
23
71180
2729
Oni prouzroče tutnjavu u trbuhu i ostave čak i fotografe u strahopoštovanju
01:13
watching the spectacle.
24
73933
1151
promatrajući taj spektakl.
01:15
These rockets use experimental motors like nitrous oxide.
25
75108
2786
Te rakete koriste eksperimentalne motore poput dušikovog oksida.
01:17
They use solid propellant most frequently.
26
77918
2001
Najčešće koriste čvrsta goriva.
01:19
It's a strange kind of love.
27
79943
1339
To je čudna vrsta ljubavi.
01:21
RocketMavericks.com with my photos, if you want to learn about this,
28
81306
3208
Imamo Rocketmavericks.com web stranicu s mojim fotografijama,
ukoliko želite naučiti više o tome -- sudjelovati, biti promatrač.
01:24
participate, be a spectator.
29
84538
1336
01:25
We had to call it Rocket Mavericks.
30

1977
Disidenti. Morali smo to nazvati Raketni disidenti.
01:27
This one was great, went to 100,000 feet -- but didn't quite.
31
87899
2874
Ova je bila odlična. Uzdigla se na 100.000 stopa,
ali nije baš -- zapravo, zabila se 11 stopa u čvrstu glinu,
01:30
Actually, it went 11 feet into solid clay and became a bunker-buster.
32
90797
3277
i postala je oružje za penetriranje zemljane površine,
bušeći duboko u glinu -- morali smo je iskopavati.
01:34
It had to be dug out.
33
94098
1424
01:35
Rockets often spiral out of control if you put too much propellant in them.
34
95546
3752
Rakete se često otmu kontroli ako stavite previše goriva u njih.
Ovo je bila utrka vuče.
01:39
Here was a drag race.
35
99322
1159
Po noći možete u sekundi vidjeti što se dogodilo,
01:40
At night you can see what happened in a second;
36
100505
2240
tijekom dana zovemo ih zemljane psine.
01:42
in daytime, we call them land sharks.
37
102769
1772
01:44
Sometimes they just explode before your eyes or come down supersonic.
38
104565
3287
Ponekad jednostavno eksplodiraju pred vašim očima, ili se spuštaju brzinom zvuka.
(Smijeh)
01:47
(Laughter)
39
107876
1009
01:48
To take this shot, I did what I often do, which is go way beyond the pads,
40
108909
3477
Kako bih mogao ovako lansirati raketu, činim ono što često činim,
a to je da se dosta udaljim od platformi gdje nema nijednog promatrača.
01:52
where none of the spectators are.
41
112410
1600
A ako možemo pokrenuti video, pokazati ću vam što je trebalo
01:54
And if we can run the video, I'll show you what it took
42
114034
2580
da ovaj DreamWorks bude lansiran.
01:56
to get this DreamWorks shot.
43
116638
1347
01:58
(Video) Voices: Woo-hoo! Yeah. Nice.
44
118690
1976
Video: Glasovi: Da. Lijepo.
02:00
Steve Jurvetson: They realize the computer failed, they're yelling "Deploy!"
45
120690
3886
Steve Jurvetson: Ovo je rijetkost. Ovdje su shvatili da je računalo zakazalo.
Viču da se pokrene. Viču da se pokrene. Glasovi: O, sranje.
02:04
(Video) Man: Oh, shit.
46
124600
1151
02:05
SJ: This is when they realize everything's gone haywire.
47
125775
2629
SJ: Ovo je kada su shvatili da je sve u raketi u neredu.
Glasovi: Krenut će balistički. O, sranje.
02:08
(Video) Man: It's going ballistic.
48
128428
1621
SJ: A ja ću samo ušutjeti.
Glasovi: Ne.
02:10
SJ: I'll just be quiet.
49
130073
1151
02:11
(Video) Woman: No!
50
131248
1151
02:12
Come on, come on, come on.
51
132423
2000
Gore, gore, gore.
02:18
SJ: And that's me over there, taking photos the whole way.
52
138330
2762
SJ: A to sam ja tamo preko, fotografiram cijelo vrijeme.
02:22
Things often go wrong.
53
142321
1151
Stvari često pođu krivo.
02:23
Some people watch this because of a NASCAR-like fascination
54
143496
3273
Neki ljudi gledaju ovaj događaj zbog fascinacije pomalo nalik na NASCAR,
02:26
with things bumping and grinding.
55
146793
1635
sa stvarima koje se sudaraju, drobe, padobrani koji izgore prilikom pada --
02:28
Burning the parachute as it fell. That was last weekend.
56
148452
2717
to je bilo prošli vikend.
Ovaj momak je lansirao raketu, bila je to brzina zvuka,
02:31
This guy went up, went supersonic, ripped the fin can off.
57
151193
2730
cijela dvorišna rasprodaja na nebu,
02:33
The art sale in the sky.
58
153947
1151
i gorući komadi metala koji se vraćaju natrag.
02:35
A burning metal hunk coming back.
59
155122
1579
02:36
These things dropped down from above all through the weekend
60
156725
2818
Te stvari bi padale dolje tijekom cijelog vikenda
lansiranja raketa, nakon lansiranja raketa, nakon lansiranja raketa.
02:39
of rocket launch after rocket launch.
61
159567
1790
To je ritam koji ne možete baš zamisliti.
02:41
It's a cadence you can't quite imagine.
62
161381
1894
I na mnoge načine, pokušavam uhvatiti te nezgode --
02:43
I try to capture the mishaps; it's a challenge in photography
63
163299
2876
to je izazov u fotografiji kada se te stvari događaju
02:46
when these things take place in a fraction of a second.
64
166199
2594
u djeliću sekunde.
02:48
Why do it? For things like this:
65
168817
1531
Zašto to rade? To je zbog stvari poput ovih:
02:50
Gene from Alabama drives out there
66
170372
2147
Gene iz Alabame vozi dovde
02:52
with this rocket he's built with X-ray sensors, video cameras,
67
172543
3072
s tom raketom koju je izradio, s senzorima x zraka, video kamerama,
02:55
festooned with electronics.
68
175639
1291
hrpom elektronike, i uspije doći na 100.000 stopa,
02:56
He succeeds getting to 100,000 feet,
69
176954
1721
02:58
leaving the atmosphere, seeing a thin blue line of space.
70
178699
2680
napuštajući atmosferu, ugledavši tanku plavu liniju svemira.
Taj veličanstven prikaz --
03:01
It is this breathtaking image -- success, of course -- that motivates us
71
181403
3392
uspjeh, naravno - je ono što nas motivira.
03:04
and motivates kids to follow and understand rocket science,
72
184819
2787
I motivira djecu da slijede i shvate raketnu znanost,
03:07
understand the importance of physics and math
73
187630
2104
da shvate važnost fizike i matematike,
03:09
and, in many ways, to have that awe at exploration
74
189758
2335
i u mnogim pogledima da imaju tu neku vrstu strahopoštovanja prema istraživanju
granica nepoznatog.
03:12
of the frontiers of the unknown.
75
192117
1534
03:13
Thank you.
76
193675
1151
Hvala vam.
03:14
