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

3000
Podnevi sem finančnik, ob vikendih pa ljubim rakete.
00:21
I love photography, I love rockets,
1
3000
2000
Rad fotografiram, rad imam rakete
00:23
and I'm going to talk to you about a hobby that can scale
2
5000
2000
zato vam bom govorilo hobiju, ki se lahko raširi v strast
00:25
and show you some photos that I've taken over the years
3
7000
2000
in prikazal nekaj fotografij, ki sem jih posnel tekom let
00:27
with kids like these; kids that hopefully will grow up to love rocketry
4
9000
3000
s takšnimi otroci, ki bodo vzljubili raketarstvo
00:30
and eventually become maybe another Richard Branson or Diamandis.
5
12000
3000
in morda postali naslednji Richard Branson ali Diamandis.
00:33
My son designed a rocket that became stable,
6
15000
2000
Moj sin je ustvaril raketo, ki je stabilno poletela -
00:35
a golf ball rocket -- I thought it was quite an interesting experiment
7
17000
2000
iz žogice za golf. Mislim, da je bil kar zanimiv eksperiment
00:37
in the principles of rocket science --
8
19000
2000
po principih raketne znanosti
00:39
and it flies straight as an arrow.
9
21000
2000
in poletela je naravnost kot puščica.
00:42
Baking soda and vinegar.
10
24000
2000
Soda bikarbona in kis.
00:44
Night shots are beautiful,
11
26000
2000
Nočni posnetki so prečudoviti,
00:46
piercing the Big Dipper and the Milky Way.
12
28000
2000
ko preluknjaš Veliki voz in Mlečno cesto.
00:48
Two stage rockets, rockets with video cameras on them,
13
30000
2000
Dvo-nivojske rakete, rakete z nameščeno kamero,
00:50
on-board computers logging their flights,
14
32000
2000
z računalniki, ki beležijo celoten polet.
00:52
rocket gliders that fly back to Earth.
15
34000
2000
Raketni jadralci, ki priletijo nazaj na zemljo.
00:54
I use RockSim to simulate flights before they go
16
36000
2000
Jaz uporabljam RockSim za simulacije poletov,
00:56
to see if they'll break supersonic or not,
17
38000
2000
da preverim, če bodo prebile zvočni zid
00:58
and then fly them with on-board computers to verify their performance.
18
40000
3000
in nato jih izstrelim z računalnikom, da preverim njihovo delovanje.
01:01
But to launch the really big stuff, you go to the middle of nowhere:
19
43000
2000
Ampak za izstrelitev res velikih raket, gremo tja, kjer ni nikogar -
01:03
Black Rock Desert, where dangerous things happen.
20
45000
2000
v puščavo Black Rock, kjer se dogajajo nevarne stvari.
01:05
And the boys get bigger, and the rockets get bigger. (Laughter)
21
47000
2000
In otroci rastejo, prav tako tudi rakete.
01:07
And they use motors
22
49000
2000
Uporabljajo motorje
01:09
that literally are used on cruise missile boosters.
23
51000
2000
ki se dobesedno uporabljajo na pravih raketah.
01:11
They rumble the belly and leave even photographers in awe
24
53000
2000
Prestrašijo tudi fotografe in jih pustijo v napetosti
01:13
watching the spectacle.
25
55000
2000
opazovanja spektakla.
01:15
These rockets use experimental motors like nitrous oxide.
26
57000
2000
Te rakete uprabljajo eksperimentalne motorje, npr. dušikov oksid.
01:17
They use solid propellant most frequently.
27
59000
2000
Vendar največkrat uporabljajo trdno gorivo.
01:19
It's a strange kind of love.
28
61000
2000
To je čudna ljubezen.
01:21
We have a RocketMavericks.com website with my photos
29
63000
2000
Imamo spletno stran Rocketmaverics.com z mojimi fotografijami
01:23
if you want to learn more about this, participate, be a spectator.
30
65000
2000
in če žečite več izvedeti - sodelujte, postanite opazovalec.
01:25
Mavericks: we had to call it Rocket Mavericks.
31
67000
2000
Posebneži. Morali smo jo poimenovati Raketa Posbnež.
01:27
This one was great: it went to 100,000 feet,
32
69000
2000
Ta je bila prečudovita. Dvignila se nad 30.000 metrov,
01:29
but didn't quite. Actually, it went 11 feet into the solid clay;
33
71000
2000
vendar se je zapičila v zemljo kar 3 metre globoko
01:31
and it became a bunker-buster,
34
73000
2000
in postala "uničevalec bunkerjev"
01:33
drilling down into the clay. It had to be dug out.
35
75000
2000
z naletom v trdno zemljo - morali smo jo izkopati.
01:35
Rockets often spiral out of control if you put too much propellant in them.
36
77000
2000
Rakete velikokrat pobegnejo izpod nadzora, če jo napolnimo s preveč goriva.
01:37
Here was a drag race.
37
79000
2000
Tukaj smo imeli hitrostno dirko.
01:39
At night you can see what happened in a second;
38
81000
2000
Ponoči se lahko vidi, kaj se zgodi v sekundi,
01:41
in daytime, we call them land sharks.
39
83000
3000
podnevi jim pa rečemo zemljski morski psi.
01:44
Sometimes they just explode before your eyes or come down supersonic.
40
86000
2000
Včasih eksplodirajo pred očmi, drugič priletijo z nadzvočno hitrostjo na tla.
01:46
(Laughter)
41
88000
2000
(smeh)
01:48
To take this shot, I do what I often do,
42
90000
2000
Za ta posnetek sem naredil nekaj, kar ponavadi naredim,
01:50
which is go way beyond the pads where none of the other spectators are.
43
92000
2000
in sicer, da grem daleč stran od izstrelišča, kjer ni nikogar.
01:52
And if we can run the video, I'll show you what it took
44
94000
2000
In če lahko pokažem video, boste videli, kaj je potrebno
01:54
to get this DreamWorks shot.
45
96000
3000
da nastane tak sanjski posnetek.
01:58
(Video) Voices: Woohoo! Yeah. Nice.
46
100000
2000
Video: Zvoki: Super.
02:00
Steve Jurvetson: This is rare. Here's where they realized the computer's failed.
47
102000
3000
Steve Jurvetson: To ni pogosto. Tukaj so ugotovili, da je računalnik odpovedal.
02:03
They're yelling deploy. Voices: Oh shit.
48
105000
2000
Kričijo naj igrajo. Kričijo naj igrajo. Zvoki: Oh, sranje.
02:05
SJ: This is when they realize everything on board's gone haywire.
49
107000
2000
SJ: Tukaj so ugotovili, da gre na krovu rakete vse narobe.
02:07
Voices: It's going ballistic. Oh shit.
50
109000
1000
Zvoki: Vrača se. Oh, sranje.
02:08
SJ: And I'll just be quiet.
51
110000
1000
SJ: In jaz bom samo tiho.
02:09
Voices: No.
52
111000
3000
Zvoki: Ne.
02:12
Up, up, up.
53
114000
2000
Gor, gor, gor.
02:18
SJ: And that's me over there, taking photos the whole way.
54
120000
2000
SJ: In tam stojim jaz, medtem ko fotografiram celotno zadevo.
02:22
Things often go wrong.
55
124000
2000
Zadeve gredo pogosto narobe.
02:24
Some people watch this event because of a NASCAR-like fascination
56
126000
2000
Nekateri gledajo na ta dogodek kot NASCAR občudovanje
02:26
with things bumping and grinding. Burning the parachute as it fell --
57
128000
2000
s stvarmi, ki se zaletavajo, zažigajo padala, ko pada proti tlom -
02:28
that was last weekend.
58
130000
2000
to je bilo prejšnji vikend.
02:30
This guy went up, went supersonic, ripped the fin can off --
59
132000
2000
Tale tip je šel navzgor, prišel do nadzvočne hitrosti, mu oddtrgalo del,
02:32
yard sale in the sky --
60
134000
2000
ga raznelo po nebu
02:34
and a burning metal hunk coming back.
61
136000
2000
in goreči deli so prišli nazaj.
02:36
These things would drop down from above all through the weekend
62
138000
2000
Te stvari so padale z neba še cel vikend
02:38
of rocket launch after rocket launch after rocket launch.
63
140000
2000
od izstrelitve raket, ki stalno potekajo.
02:40
It's a cadence you can't quite imagine.
64
142000
2000
To je kadenca, ki si jo težko predstavljate.
02:42
And in many ways, I try to capture the mishaps;
65
144000
2000
In v mnogih letih sem poskušal to zajeti -
02:44
it's the challenge in photography when these things all take place
66
146000
2000
to je izziv v fotografiji, ko se dogajajo take stvari
02:46
in a fraction of a second.
67
148000
2000
v le delčku sekunde.
02:48
Why do they do it? It's for things like this:
68
150000
2000
Zakaj to sploh počnjo? Predvsem zaradi:
02:50
Gene from Alabama drives out there
69
152000
2000
Gene iz Alabame se pripelje do tam
02:52
with this rocket that he's built with X-ray sensors, video cameras,
70
154000
3000
s svojo raketo, ki jo je zgradil, z detektorji rendgenskih žarkov, kamerami,
02:55
festooned with electronics, and he succeeds getting to 100,000 feet,
71
157000
3000
naložene z elektroniko in uspelo mu je doseči 30km,
02:58
leaving the atmosphere, seeing a thin blue line of space.
72
160000
2000
zapustiti atmosfero in videti tanko linijo vesolja.
03:00
It is this breathtaking image --
73
162000
2000
To je sapo jemajoča fotografija -
03:02
success, of course -- that motivates us
74
164000
2000
uspeh, seveda - ki nas motivira.
03:04
and motivates kids to follow and understand rocket science:
75
166000
3000
In motivira otroke, ki nam sledijo in razumejo raketno znanost,
03:07
to understand the importance of physics and math
76
169000
2000
kot razumevanje pomembnosti fizike in matematike,
03:09
and, in many ways, to sort of have that awe at exploration
77
171000
2000
in v mnogih pogledih imeti bojazen pri raziskovanju
03:11
of the frontiers of the unknown.
78
173000
2000
nam neznaega.
03:13
Thank you.
79
175000
2000
Hvala.
03:15
(Applause)
