By day, I'm a venture capitalist. On weekends, I love rockets.
0

3000
平時，我是一個風險投資家。週末，我喜歡玩火箭。
00:21
I love photography, I love rockets,
1
3000
2000
我熱愛攝影，我熱愛火箭，
00:23
and I'm going to talk to you about a hobby that can scale
2
5000
2000
我今天要跟大家聊聊這個可大可小的嗜好，
00:25
and show you some photos that I've taken over the years
3
7000
2000
而且還要展示一下這些年來拍的照片，
00:27
with kids like these; kids that hopefully will grow up to love rocketry
4
9000
3000
都是和這些孩子們一起拍的，希望他們長大了也熱愛火箭技術，
00:30
and eventually become maybe another Richard Branson or Diamandis.
5
12000
3000
說不定最後成為第二個Richard Branson （英國傳奇富翁，維珍品牌創始人）或者Diamandis （Peter H. Diamandis ，創立X PRIZE Foundation鼓勵民間航空產業）
00:33
My son designed a rocket that became stable,
6
15000
2000
我兒子設計了一個火箭，最後是這個樣子——
00:35
a golf ball rocket -- I thought it was quite an interesting experiment
7
17000
2000
一個高爾夫球火箭，我覺得這是個非常有意思的實驗，
00:37
in the principles of rocket science --
8
19000
2000
依照火箭科學的原理，
00:39
and it flies straight as an arrow.
9
21000
2000
飛得像箭一樣直。
00:42
Baking soda and vinegar.
10
24000
2000
這裡用的是烤麵包的蘇打和醋。
00:44
Night shots are beautiful,
11
26000
2000
夜景照片非常漂亮，
00:46
piercing the Big Dipper and the Milky Way.
12
28000
2000
劃過北斗七星和銀河。
00:48
Two stage rockets, rockets with video cameras on them,
13
30000
2000
兩段式火箭，搭載攝影機的火箭
00:50
on-board computers logging their flights,
14
32000
2000
機載電腦記錄著飛行過程。
00:52
rocket gliders that fly back to Earth.
15
34000
2000
火箭滑翔機返回地面。
00:54
I use RockSim to simulate flights before they go
16
36000
2000
在發射前我用RockSim（火箭模型設計和仿真軟件）模擬飛行過程，
00:56
to see if they'll break supersonic or not,
17
38000
2000
看看它們是否能突破音速，
00:58
and then fly them with on-board computers to verify their performance.
18
40000
3000
然後才發射並用機載電腦確認其性能。
01:01
But to launch the really big stuff, you go to the middle of nowhere:
19
43000
2000
但是要想發射真正的大傢伙，就要去到這種不毛之地——
01:03
Black Rock Desert, where dangerous things happen.
20
45000
2000
黑岩沙漠，那兒常發生一些危險的事情。
01:05
And the boys get bigger, and the rockets get bigger. (Laughter)
21
47000
2000
隨著男生們的年紀變大，火箭也跟著變大。
01:07
And they use motors
22
49000
2000
他們使用發動機，
01:09
that literally are used on cruise missile boosters.
23
51000
2000
使用貨真價實的巡航導彈推進器。
01:11
They rumble the belly and leave even photographers in awe
24
53000
2000
火箭在隆隆巨響中發射升空，讓攝影師目瞪口呆地
01:13
watching the spectacle.
25
55000
2000
看著這壯觀的景象。
01:15
These rockets use experimental motors like nitrous oxide.
26
57000
2000
這些火箭使用的是試驗性的發動機，如一氧化二氮。
01:17
They use solid propellant most frequently.
27
59000
2000
他們最常使用的是固體推進劑。
01:19
It's a strange kind of love.
28
61000
2000
這是一種奇怪的愛好。
01:21
We have a RocketMavericks.com website with my photos
29
63000
2000
我們有一個網站：Rocketmavericks.com ，上面有我的照片，
01:23
if you want to learn more about this, participate, be a spectator.
30
65000
2000
如果你想瞭解更多，——加入我們，做個觀眾。
01:25
Mavericks: we had to call it Rocket Mavericks.
31
67000
2000
無政府主義份子。我們叫這個是火箭無政府主義份子。
01:27
This one was great: it went to 100,000 feet,
32
69000
2000
這個傢伙很厲害。它飛了10萬英尺。
01:29
but didn't quite. Actually, it went 11 feet into the solid clay;
33
71000
2000
但其實不夠10萬——事實上，它向地下推進了11英尺，
01:31
and it became a bunker-buster,
34
73000
2000
成了個地堡炸彈。
01:33
drilling down into the clay. It had to be dug out.
35
75000
2000
鑽進地裡去了——我們不得不把它挖出來。
01:35
Rockets often spiral out of control if you put too much propellant in them.
36
77000
2000
如果放了過多的推進劑，火箭經常會失控進入螺旋狀態。
01:37
Here was a drag race.
37
79000
2000
就像短程加速賽車。
01:39
At night you can see what happened in a second;
38
81000
2000
在晚上就能看見一秒內發生了什麽，
01:41
in daytime, we call them land sharks.
39
83000
3000
白天我們叫這個是陸地鯊魚。
01:44
Sometimes they just explode before your eyes or come down supersonic.
40
86000
2000
有時就在你眼前爆炸了，或者以超音速直衝下來。
01:46
(Laughter)
41
88000
2000
（笑聲）
01:48
To take this shot, I do what I often do,
42
90000
2000
爲了拍到這張照片，我採用我的一貫做法，
01:50
which is go way beyond the pads where none of the other spectators are.
43
92000
2000
走到離發射台很遠很遠的地方，除我以外沒別人了。
01:52
And if we can run the video, I'll show you what it took
44
94000
2000
我們可以播放一段影片，就可以給你們看看
01:54
to get this DreamWorks shot.
45
96000
3000
這個夢工廠大片是怎麼拍出來的了。
01:58
(Video) Voices: Woohoo! Yeah. Nice.
46
100000
2000
影片聲音：耶！太棒了。
02:00
Steve Jurvetson: This is rare. Here's where they realized the computer's failed.
47
102000
3000
Steve Jurvetson：這種情況很少見。這裡他們發現電腦出錯了。
02:03
They're yelling deploy. Voices: Oh shit.
48
105000
2000
他們大喊著堅持下去。影片聲音：啊，完蛋了！
02:05
SJ: This is when they realize everything on board's gone haywire.
49
107000
2000
Steve Jurvetson: 這裡他們發現整個火箭都出問題了。
02:07
Voices: It's going ballistic. Oh shit.
50
109000
1000
影片聲音：要撞擊了。。。唉，糟糕！
02:08
SJ: And I'll just be quiet.
51
110000
1000
Steve Jurvetson: 我就啥都不說了。
02:09
Voices: No.
52
111000
3000
影片聲音：不要！！
02:12
Up, up, up.
53
114000
2000
向上，向上，向上。
02:18
SJ: And that's me over there, taking photos the whole way.
54
120000
2000
Steve Jurvetson: 那邊那個就是我，正在拍下這整個過程。
02:22
Things often go wrong.
55
124000
2000
錯誤經常發生。
02:24
Some people watch this event because of a NASCAR-like fascination
56
126000
2000
有人喜歡看這些因為這就像是全美普通汽車拉力賽。
02:26
with things bumping and grinding. Burning the parachute as it fell --
57
128000
2000
爆炸啊，肢解啊，降落傘邊燒邊掉下來啊——
02:28
that was last weekend.
58
130000
2000
這是上個週末的事。
02:30
This guy went up, went supersonic, ripped the fin can off --
59
132000
2000
這個傢伙發射升空，超越音速，尾艙脫離了，
02:32
yard sale in the sky --
60
134000
2000
所有的東西在空中散開來，
02:34
and a burning metal hunk coming back.
61
136000
2000
最後一大片金屬燃燒著回到地面。
02:36
These things would drop down from above all through the weekend
62
138000
2000
整個發射火箭的週末，就是這些東西，
02:38
of rocket launch after rocket launch after rocket launch.
63
140000
2000
發射，掉下來，發射，掉下來。
02:40
It's a cadence you can't quite imagine.
64
142000
2000
你都想不到這是多麼有節奏。
02:42
And in many ways, I try to capture the mishaps;
65
144000
2000
我試圖用很多方式捕捉小事故——
02:44
it's the challenge in photography when these things all take place
66
146000
2000
這是對攝影技術的挑戰，因為一切這些都發生在
02:46
in a fraction of a second.
67
148000
2000
幾分之一秒。
02:48
Why do they do it? It's for things like this:
68
150000
2000
為什麼他們要這麼做？一切都是為了：
02:50
Gene from Alabama drives out there
69
152000
2000
來自阿拉巴馬的吉恩千里迢迢驅車到此，
02:52
with this rocket that he's built with X-ray sensors, video cameras,
70
154000
3000
帶著他製造的火箭，上面有X光感應器，攝影機，
02:55
festooned with electronics, and he succeeds getting to 100,000 feet,
71
157000
3000
被各種電子設備打扮得花枝招展，然後他成功升到十萬英尺，
02:58
leaving the atmosphere, seeing a thin blue line of space.
72
160000
2000
脫離了大氣層，瞥見了這一抹蔚藍的太空。
03:00
It is this breathtaking image --
73
162000
2000
正是這種令人屏息的景象——
03:02
success, of course -- that motivates us
74
164000
2000
當然還有成就感——成為我們的動力。
03:04
and motivates kids to follow and understand rocket science:
75
166000
3000
同時是推動孩子們去探索並理解火箭學，
03:07
to understand the importance of physics and math
76
169000
2000
理解物理和數學的重要性，
03:09
and, in many ways, to sort of have that awe at exploration
77
171000
2000
並且在很多方面保持某程度上的敬畏之心，
03:11
of the frontiers of the unknown.
78
173000
2000
當他們在未知世界的邊緣探險時。
03:13
Thank you.
79
175000
2000
謝謝大家。
03:15
(Applause)

ABOUT THE SPEAKER
Steve Jurvetson - Venture capitalistVenture capitalist Steve Jurvetson (he brought you Hotmail) is one of the most influential funders and thinkers in Silicon Valley. He's also an enthusiastic hobbyist, blogger and Flickr-er.
Why you should listen
"Scary-smart" is a phrase that comes up in coverage of Steve Jurvetson. In his work at Draper Fisher Jurvetson, he's taken early and influential positions on some world-changing tech ideas -- such as the viral marketing of Hotmail. Now, he's looking forward into nanotech and synthetic life, and the Valley is looking over his shoulder.
He's a passionate advocate of new thinking on technology -- especially on his thoughtful and funny blog, the J Curve. His massive Flickr set documents his many passions -- speaking at conferences, meeting like-minded geeks, shooting off rockets.
