By day, I'm a venture capitalist. On weekends, I love rockets.

Po danu ja sam ulagač u nove poslovne poduhvate. Tijekom vikenda, volim rakete.
00:21
I love photography, I love rockets,
1
3000
2000
Volim fotografiju, volim rakete,
00:23
and I'm going to talk to you about a hobby that can scale
2
5000
2000
i pričat ću vam o hobiju koji može narasti
00:25
and show you some photos that I've taken over the years
3
7000
2000
i pokazati vam neke fotografije koje sam snimio tijekom godina
00:27
with kids like these; kids that hopefully will grow up to love rocketry
4
9000
3000
s djecom kao što su ova, djeca koja će, nadam se, odrasti i zavoljeti modeliranje raketa,
00:30
and eventually become maybe another Richard Branson or Diamandis.
5
12000
3000
i naposljetku možda postati idući Richard Branson ili Diamandis.
00:33
My son designed a rocket that became stable,
6
15000
2000
Moj sin je dizajnirao raketu koja je postala stabilna --
00:35
a golf ball rocket -- I thought it was quite an interesting experiment
7
17000
2000
raketu loptice za golf. Mislio sam kako je to poprilično zanimljiv eksperiment
00:37
in the principles of rocket science --
8
19000
2000
prema načelima raketne znanosti,
00:39
and it flies straight as an arrow.
9
21000
2000
i leti ravno poput strijele.
00:42
Baking soda and vinegar.
10
24000
2000
Soda i ocat.
00:44
Night shots are beautiful,
11
26000
2000
Noćne snimke su prekrasne,
00:46
piercing the Big Dipper and the Milky Way.
12
28000
2000
prodoran Veliki medvjed i Mliječna staza.
00:48
Two stage rockets, rockets with video cameras on them,
13
30000
2000
Dvorazinske rakete, rakete s video kamerama na njima,
00:50
on-board computers logging their flights,
14
32000
2000
s ugrađenim računalima koja bilježe njihove letove.
00:52
rocket gliders that fly back to Earth.
15
34000
2000
Raketne jedrilice koje lete natrag na zemlju.
00:54
I use RockSim to simulate flights before they go
16
36000
2000
Koristim RockSim kako bih simulirao letove prije nego odu
00:56
to see if they'll break supersonic or not,
17
38000
2000
da vidim hoće li probiti zvučni zid ili ne,
00:58
and then fly them with on-board computers to verify their performance.
18
40000
3000
i zatim ih lansiram s ugrađenim računalima kako bih provjerio njihovu izvedbu.
01:01
But to launch the really big stuff, you go to the middle of nowhere:
19
43000
2000
Ali lansirati doista velike stvari, ići usred ničega --
01:03
Black Rock Desert, where dangerous things happen.
20
45000
2000
Black Rock pustinja, gdje se opasne stvari događaju.
01:05
And the boys get bigger, and the rockets get bigger. (Laughter)
21
47000
2000
I dečki postaju veći, i rakete postaju veće.
01:07
And they use motors
22
49000
2000
I koriste motore
01:09
that literally are used on cruise missile boosters.
23
51000
2000
koje doslovno upotrebljavaju za krstarenje projektilnih potisnika.
01:11
They rumble the belly and leave even photographers in awe
24
53000
2000
Oni prouzroče tutnjavu u trbuhu i ostave čak i fotografe u strahopoštovanju
01:13
watching the spectacle.
25
55000
2000
promatrajući taj spektakl.
01:15
These rockets use experimental motors like nitrous oxide.
26
57000
2000
Te rakete koriste eksperimentalne motore poput dušikovog oksida.
01:17
They use solid propellant most frequently.
27
59000
2000
Najčešće koriste čvrsta goriva.
01:19
It's a strange kind of love.
28
61000
2000
To je čudna vrsta ljubavi.
01:21
We have a RocketMavericks.com website with my photos
29
63000
2000
Imamo Rocketmavericks.com web stranicu s mojim fotografijama,
01:23
if you want to learn more about this, participate, be a spectator.
30
65000
2000
ukoliko želite naučiti više o tome -- sudjelovati, biti promatrač.
01:25
Mavericks: we had to call it Rocket Mavericks.
31
67000
2000
Disidenti. Morali smo to nazvati Raketni disidenti.
01:27
This one was great: it went to 100,000 feet,
32
69000
2000
Ova je bila odlična. Uzdigla se na 100.000 stopa,
01:29
but didn't quite. Actually, it went 11 feet into the solid clay;
33
71000
2000
ali nije baš -- zapravo, zabila se 11 stopa u čvrstu glinu,
01:31
and it became a bunker-buster,
34
73000
2000
i postala je oružje za penetriranje zemljane površine,
01:33
drilling down into the clay. It had to be dug out.
35
75000
2000
bušeći duboko u glinu -- morali smo je iskopavati.
01:35
Rockets often spiral out of control if you put too much propellant in them.
36
77000
2000
Rakete se često otmu kontroli ako stavite previše goriva u njih.
01:37
Here was a drag race.
37
79000
2000
Ovo je bila utrka vuče.
01:39
At night you can see what happened in a second;
38
81000
2000
Po noći možete u sekundi vidjeti što se dogodilo,
01:41
in daytime, we call them land sharks.
39
83000
3000
tijekom dana zovemo ih zemljane psine.
01:44
Sometimes they just explode before your eyes or come down supersonic.
40
86000
2000
Ponekad jednostavno eksplodiraju pred vašim očima, ili se spuštaju brzinom zvuka.
01:46
(Laughter)
41
88000
2000
(Smijeh)
01:48
To take this shot, I do what I often do,
42
90000
2000
Kako bih mogao ovako lansirati raketu, činim ono što često činim,
01:50
which is go way beyond the pads where none of the other spectators are.
43
92000
2000
a to je da se dosta udaljim od platformi gdje nema nijednog promatrača.
01:52
And if we can run the video, I'll show you what it took
44
94000
2000
A ako možemo pokrenuti video, pokazati ću vam što je trebalo
01:54
to get this DreamWorks shot.
45
96000
3000
da ovaj DreamWorks bude lansiran.
01:58
(Video) Voices: Woohoo! Yeah. Nice.
46
100000
2000
Video: Glasovi: Da. Lijepo.
02:00
Steve Jurvetson: This is rare. Here's where they realized the computer's failed.
47
102000
3000
Steve Jurvetson: Ovo je rijetkost. Ovdje su shvatili da je računalo zakazalo.
02:03
They're yelling deploy. Voices: Oh shit.
48
105000
2000
Viču da se pokrene. Viču da se pokrene. Glasovi: O, sranje.
02:05
SJ: This is when they realize everything on board's gone haywire.
49
107000
2000
SJ: Ovo je kada su shvatili da je sve u raketi u neredu.
02:07
Voices: It's going ballistic. Oh shit.
50
109000
1000
Glasovi: Krenut će balistički. O, sranje.
02:08
SJ: And I'll just be quiet.
51
110000
1000
SJ: A ja ću samo ušutjeti.
02:09
Voices: No.
52
111000
3000
Glasovi: Ne.
02:12
Up, up, up.
53
114000
2000
Gore, gore, gore.
02:18
SJ: And that's me over there, taking photos the whole way.
54
120000
2000
SJ: A to sam ja tamo preko, fotografiram cijelo vrijeme.
02:22
Things often go wrong.
55
124000
2000
Stvari često pođu krivo.
02:24
Some people watch this event because of a NASCAR-like fascination
56
126000
2000
Neki ljudi gledaju ovaj događaj zbog fascinacije pomalo nalik na NASCAR,
02:26
with things bumping and grinding. Burning the parachute as it fell --
57
128000
2000
sa stvarima koje se sudaraju, drobe, padobrani koji izgore prilikom pada --
02:28
that was last weekend.
58
130000
2000
to je bilo prošli vikend.
02:30
This guy went up, went supersonic, ripped the fin can off --
59
132000
2000
Ovaj momak je lansirao raketu, bila je to brzina zvuka,
02:32
yard sale in the sky --
60
134000
2000
cijela dvorišna rasprodaja na nebu,
02:34
and a burning metal hunk coming back.
61
136000
2000
i gorući komadi metala koji se vraćaju natrag.
02:36
These things would drop down from above all through the weekend
62
138000
2000
Te stvari bi padale dolje tijekom cijelog vikenda
02:38
of rocket launch after rocket launch after rocket launch.
63
140000
2000
lansiranja raketa, nakon lansiranja raketa, nakon lansiranja raketa.
02:40
It's a cadence you can't quite imagine.
64
142000
2000
To je ritam koji ne možete baš zamisliti.
02:42
And in many ways, I try to capture the mishaps;
65
144000
2000
I na mnoge načine, pokušavam uhvatiti te nezgode --
02:44
it's the challenge in photography when these things all take place
66
146000
2000
to je izazov u fotografiji kada se te stvari događaju
02:46
in a fraction of a second.
67
148000
2000
u djeliću sekunde.
02:48
Why do they do it? It's for things like this:
68
150000
2000
Zašto to rade? To je zbog stvari poput ovih:
02:50
Gene from Alabama drives out there
69
152000
2000
Gene iz Alabame vozi dovde
02:52
with this rocket that he's built with X-ray sensors, video cameras,
70
154000
3000
s tom raketom koju je izradio, s senzorima x zraka, video kamerama,
02:55
festooned with electronics, and he succeeds getting to 100,000 feet,
71
157000
3000
hrpom elektronike, i uspije doći na 100.000 stopa,
02:58
leaving the atmosphere, seeing a thin blue line of space.
72
160000
2000
napuštajući atmosferu, ugledavši tanku plavu liniju svemira.
03:00
It is this breathtaking image --
73
162000
2000
Taj veličanstven prikaz --
03:02
success, of course -- that motivates us
74
164000
2000
uspjeh, naravno - je ono što nas motivira.
03:04
and motivates kids to follow and understand rocket science:
75
166000
3000
I motivira djecu da slijede i shvate raketnu znanost,
03:07
to understand the importance of physics and math
76
169000
2000
da shvate važnost fizike i matematike,
03:09
and, in many ways, to sort of have that awe at exploration
77
171000
2000
i u mnogim pogledima da imaju tu neku vrstu strahopoštovanja prema istraživanju
03:11
of the frontiers of the unknown.
78
173000
2000
granica nepoznatog.
03:13
Thank you.
79
175000
2000
Hvala vam.
03:15
(Applause)
