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

3000
Cez deň som odvážny kapitalista. Cez víkendy milujem rakety.
00:21
I love photography, I love rockets,
1
3000
2000
Milujem fotografie, milujem rakety
00:23
and I'm going to talk to you about a hobby that can scale
2
5000
2000
a idem vám porozprávať o mojom koníčku, ktorý vie rásť,
00:25
and show you some photos that I've taken over the years
3
7000
2000
a ukázať nejaké fotky, ktoré som spravil v priebehu rokov
00:27
with kids like these; kids that hopefully will grow up to love rocketry
4
9000
3000
s deťmi ako sú tieto, deti, ktoré, dúfajme, vyrastú k láske k raketám,
00:30
and eventually become maybe another Richard Branson or Diamandis.
5
12000
3000
a nakoniec sa možno stanú ďalším Richardom Bransonom alebo Diamandisom.
00:33
My son designed a rocket that became stable,
6
15000
2000
Môj syn navrhol raketu, ktorá sa stala stabilnou --
00:35
a golf ball rocket -- I thought it was quite an interesting experiment
7
17000
2000
raketa - golfová loptička. Myslel som si, že to bol celkom zaujímavý pokus
00:37
in the principles of rocket science --
8
19000
2000
v princípoch raketovej vedy,
00:39
and it flies straight as an arrow.
9
21000
2000
a lieta to rovno ako šíp.
00:42
Baking soda and vinegar.
10
24000
2000
Sóda bikarbóna a ocot.
00:44
Night shots are beautiful,
11
26000
2000
Večerné odpaly sú nádherné,
00:46
piercing the Big Dipper and the Milky Way.
12
28000
2000
pretínajúc Veľký Voz a Mliečnu Dráhu.
00:48
Two stage rockets, rockets with video cameras on them,
13
30000
2000
Dvoj-stupňové rakety, rakety s videokamerami,
00:50
on-board computers logging their flights,
14
32000
2000
so zabudovanými počítačmi zaznamenávajúcimi let.
00:52
rocket gliders that fly back to Earth.
15
34000
2000
Raketové klzáky, ktoré doletia späť na zem.
00:54
I use RockSim to simulate flights before they go
16
36000
2000
Používam RockSim pre simuláciu letov predtým ako vzlietnu,
00:56
to see if they'll break supersonic or not,
17
38000
2000
aby som zistil, či prelomia nadzvukovosť alebo nie,
00:58
and then fly them with on-board computers to verify their performance.
18
40000
3000
a potom ich púšťam s palubnými počítačmi, aby som overil ich výkon.
01:01
But to launch the really big stuff, you go to the middle of nowhere:
19
43000
2000
Ale odpaľovať naozaj veľké veci, je lepšie ísť do stredu ničoho --
01:03
Black Rock Desert, where dangerous things happen.
20
45000
2000
púšť Black Rock, kde sa dejú nebezpečné veci.
01:05
And the boys get bigger, and the rockets get bigger. (Laughter)
21
47000
2000
A chlapci sú väčší, a rakety sú väčšie.
01:07
And they use motors
22
49000
2000
Používajú motory,
01:09
that literally are used on cruise missile boosters.
23
51000
2000
ktoré sa doslova používajú v pohone riadených striel.
01:11
They rumble the belly and leave even photographers in awe
24
53000
2000
Brnia v bruchu a nechávajú aj fotografov užasnúť
01:13
watching the spectacle.
25
55000
2000
pri sledovaní ich predstavenia.
01:15
These rockets use experimental motors like nitrous oxide.
26
57000
2000
Tieto rakety používajú experimentálne motory ako oxid dusný.
01:17
They use solid propellant most frequently.
27
59000
2000
Používajú najčastejšie tuhé pohonné látky.
01:19
It's a strange kind of love.
28
61000
2000
Je to zvláštny druh lásky.
01:21
We have a RocketMavericks.com website with my photos
29
63000
2000
Máme rocketmavericks.com webstránku s fotkami,
01:23
if you want to learn more about this, participate, be a spectator.
30
65000
2000
ak sa o tom chcete dozvedieť viac -- zapojiť sa, byť divákom.
01:25
Mavericks: we had to call it Rocket Mavericks.
31
67000
2000
Mavericks (= podivíni). Museli sme to nazvať Rocket Mavericks.
01:27
This one was great: it went to 100,000 feet,
32
69000
2000
Táto bola skvelá. Išla do 100 000 stôp.
01:29
but didn't quite. Actually, it went 11 feet into the solid clay;
33
71000
2000
ale nie úplne -- v skutočnosti išla 11 stôp do tuhej hliny
01:31
and it became a bunker-buster,
34
73000
2000
a stala sa ničiteľom bunkrov,
01:33
drilling down into the clay. It had to be dug out.
35
75000
2000
vŕtajúcou hlboko do zeme -- musela byť vyhrabaná.
01:35
Rockets often spiral out of control if you put too much propellant in them.
36
77000
2000
Rakety sa často vymknú z pod kontroly, keď do nich dáte príliš paliva.
01:37
Here was a drag race.
37
79000
2000
To boli preteky.
01:39
At night you can see what happened in a second;
38
81000
2000
V noci môžete vidieť, čo sa stane za sekundu,
01:41
in daytime, we call them land sharks.
39
83000
3000
cez deň ich voláme žraloky súše.
01:44
Sometimes they just explode before your eyes or come down supersonic.
40
86000
2000
Niekedy jednoducho vybuchnú priamo pred vašimi očami alebo nadzvukovo zostúpia.
01:46
(Laughter)
41
88000
2000
(Smiech)
01:48
To take this shot, I do what I often do,
42
90000
2000
Aby som urobil túto fotografiu, urobil som, čo často robím,
01:50
which is go way beyond the pads where none of the other spectators are.
43
92000
2000
že som išiel ďalej za odpalisko, kde nikto iný nebol.
01:52
And if we can run the video, I'll show you what it took
44
94000
2000
A keď si môžeme pozrieť video, ukážem vám, čo to stojí
01:54
to get this DreamWorks shot.
45
96000
3000
dostať takýto DreamWorks záber.
01:58
(Video) Voices: Woohoo! Yeah. Nice.
46
100000
2000
Video: Hlasy: Áno. Pekné.
02:00
Steve Jurvetson: This is rare. Here's where they realized the computer's failed.
47
102000
3000
Steve Jurvetson: Toto je zriedkavé. Toto je, kde zistili, že počítač zlyhal.
02:03
They're yelling deploy. Voices: Oh shit.
48
105000
2000
Kričia "zapni". Kričia "zapni". Hlasy: no do ...
02:05
SJ: This is when they realize everything on board's gone haywire.
49
107000
2000
SJ: Toto je, keď zistia, že všetko na palube sa kazí.
02:07
Voices: It's going ballistic. Oh shit.
50
109000
1000
Hlasy: Ide balisticky. No do ...
02:08
SJ: And I'll just be quiet.
51
110000
1000
SJ: A ja budem iba ticho.
02:09
Voices: No.
52
111000
3000
Hlasy: Nie.
02:12
Up, up, up.
53
114000
2000
Hore, nahor, nahor.
02:18
SJ: And that's me over there, taking photos the whole way.
54
120000
2000
SJ: A tamto som ja fotografujúc to celé.
02:22
Things often go wrong.
55
124000
2000
Veci sa často nevydaria.
02:24
Some people watch this event because of a NASCAR-like fascination
56
126000
2000
Niektorí ľudia pozerajú túto udalosť kvôli fascinácii podobnej pretekom NASCAR --
02:26
with things bumping and grinding. Burning the parachute as it fell --
57
128000
2000
s nárazmi, trieštením a vzplanutím padáku keď dopadá na zem --
02:28
that was last weekend.
58
130000
2000
čo sa stalo minulý týždeň.
02:30
This guy went up, went supersonic, ripped the fin can off --
59
132000
2000
Táto raketa vystúpala, išla nadzvukovo, odtrhla krídielka --
02:32
yard sale in the sky --
60
134000
2000
výpredaj na oblohe --
02:34
and a burning metal hunk coming back.
61
136000
2000
a zvuk horiaceho kusu kovu vracájuci sa späť.
02:36
These things would drop down from above all through the weekend
62
138000
2000
Tieto veci padajú na zem z oblohy celý víkend
02:38
of rocket launch after rocket launch after rocket launch.
63
140000
2000
odpalov rakiet a ďalších a ďalších odpalov.
02:40
It's a cadence you can't quite imagine.
64
142000
2000
Je to kadencia, ktorú si ani neviete predstaviť.
02:42
And in many ways, I try to capture the mishaps;
65
144000
2000
A v mnohých zmysloch sa vlastne snažím zachytiť nepodarky --
02:44
it's the challenge in photography when these things all take place
66
146000
2000
je to výzva vo fotografovaní, keďže tieto veci sa udejú
02:46
in a fraction of a second.
67
148000
2000
v zlomku sekundy.
02:48
Why do they do it? It's for things like this:
68
150000
2000
Prečo to robia? Pre toto:
02:50
Gene from Alabama drives out there
69
152000
2000
Gene z Alabamy tam príde
02:52
with this rocket that he's built with X-ray sensors, video cameras,
70
154000
3000
s raketou, ktorú postavil, s röntgenovými senzormi, videokamerami,
02:55
festooned with electronics, and he succeeds getting to 100,000 feet,
71
157000
3000
okrášlenú elektronikou, a podarí sa mu ju dostať do 100 tisíc stôp (30km)
02:58
leaving the atmosphere, seeing a thin blue line of space.
72
160000
2000
opustí atmosféru, vidiac tenkú modrú líniu vesmíru.
03:00
It is this breathtaking image --
73
162000
2000
Toto je dychvyrážajúci obrázok-
03:02
success, of course -- that motivates us
74
164000
2000
úspech, samozrejme -- ktorý nás motivuje.
03:04
and motivates kids to follow and understand rocket science:
75
166000
3000
A motivuje deti, aby nasledovali a pochopili vedu o raketách,
03:07
to understand the importance of physics and math
76
169000
2000
aby pochopili dôležitosť fyziky a matematiky
03:09
and, in many ways, to sort of have that awe at exploration
77
171000
2000
a aby v istom zmysle zažili ten úžas z objavovania
03:11
of the frontiers of the unknown.
78
173000
2000
hraníc nepoznaného.
03:13
Thank you.
79
175000
2000
Ďakujem vám.
03:15
(Applause)
