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

平日里，我是一个风险投资家。周末，我喜欢玩玩火箭。
00:21
I love photography, I love rockets,
1
3000
2000
我热爱摄影，热爱火箭，
00:23
and I'm going to talk to you about a hobby that can scale
2
5000
2000
我要向大家讲讲这个可大可小的业余爱好
00:25
and show you some photos that I've taken over the years
3
7000
2000
同时展示一下这些年来我拍的照片
00:27
with kids like these; kids that hopefully will grow up to love rocketry
4
9000
3000
和这样的孩子一起拍的，这些孩子长大后会热爱火箭技术，
00:30
and eventually become maybe another Richard Branson or Diamandis.
5
12000
3000
可能长大后会成为Richard Branson或Diamandis这样的人(二人是民间太空飞行爱好者)。
00:33
My son designed a rocket that became stable,
6
15000
2000
我儿子设计了一枚稳定的
00:35
a golf ball rocket -- I thought it was quite an interesting experiment
7
17000
2000
高尔夫球火箭。我认为是对火箭科学原理的有趣实践，
00:37
in the principles of rocket science --
8
19000
2000
高尔夫球火箭。我认为是对火箭科学原理的有趣实践，
00:39
and it flies straight as an arrow.
9
21000
2000
飞得像箭一样直。
00:42
Baking soda and vinegar.
10
24000
2000
小苏打和醋。(醋碱中和产生二氧化碳推进火箭)
00:44
Night shots are beautiful,
11
26000
2000
夜间发射非常美丽，
00:46
piercing the Big Dipper and the Milky Way.
12
28000
2000
直刺云霄。
00:48
Two stage rockets, rockets with video cameras on them,
13
30000
2000
二级火箭，火箭上有摄像头，
00:50
on-board computers logging their flights,
14
32000
2000
搭载的计算机进行飞行记录。
00:52
rocket gliders that fly back to Earth.
15
34000
2000
火箭滑翔机飞向地面。
00:54
I use RockSim to simulate flights before they go
16
36000
2000
我用Rocksim（火箭弹设计软件）模拟飞行即将发射的火箭，
00:56
to see if they'll break supersonic or not,
17
38000
2000
看看它们会不会突破音速，
00:58
and then fly them with on-board computers to verify their performance.
18
40000
3000
然后用火箭搭载计算机控制飞行，验证火箭的性能。
01:01
But to launch the really big stuff, you go to the middle of nowhere:
19
43000
2000
不过要发射真正的大家伙，就要到常有险情发生的黑岩沙漠腹地
01:03
Black Rock Desert, where dangerous things happen.
20
45000
2000
不过要发射真正的大家伙，就要到常有险情发生的黑岩沙漠腹地
01:05
And the boys get bigger, and the rockets get bigger. (Laughter)
21
47000
2000
男孩子们在长大，火箭也随之变大。
01:07
And they use motors
22
49000
2000
他们用的发动机
01:09
that literally are used on cruise missile boosters.
23
51000
2000
他们实际上用的是巡航导弹的助推火箭。
01:11
They rumble the belly and leave even photographers in awe
24
53000
2000
火箭隆隆作响发射，使得摄影师也震惊观看着壮观的场面。
01:13
watching the spectacle.
25
55000
2000
火箭隆隆作响发射，使得摄影师也震惊观看着壮观的场面。
01:15
These rockets use experimental motors like nitrous oxide.
26
57000
2000
这些火箭使用试验性发动机如氮氧发动机。
01:17
They use solid propellant most frequently.
27
59000
2000
他们最常用的是固体燃料发动机。
01:19
It's a strange kind of love.
28
61000
2000
这是一个奇怪的喜好。
01:21
We have a RocketMavericks.com website with my photos
29
63000
2000
我们有个Rocketmavericks.com网站，上面有我的照片，
01:23
if you want to learn more about this, participate, be a spectator.
30
65000
2000
如果您想了解详情 -- 参与，成为一名观众。
01:25
Mavericks: we had to call it Rocket Mavericks.
31
67000
2000
标新立异者。我们称之为火箭标新立异者。
01:27
This one was great: it went to 100,000 feet,
32
69000
2000
这枚火箭很棒。它飞到10万英尺(30公里)高，
01:29
but didn't quite. Actually, it went 11 feet into the solid clay;
33
71000
2000
不过也不十分完美，实际上，它扎进土里11英尺(4米)深，
01:31
and it became a bunker-buster,
34
73000
2000
成了一颗地堡炸弹（bunker-buster），
01:33
drilling down into the clay. It had to be dug out.
35
75000
2000
钻到土里去了，还得把它挖出来。
01:35
Rockets often spiral out of control if you put too much propellant in them.
36
77000
2000
如果加注太多推进剂，火箭经常会急速上升，失去控制。
01:37
Here was a drag race.
37
79000
2000
这是一个短程高速汽车赛。
01:39
At night you can see what happened in a second;
38
81000
2000
在晚上，您可以看到瞬间发生了什么，
01:41
in daytime, we call them land sharks.
39
83000
3000
在白天，我们称之为陆地鲨鱼。
01:44
Sometimes they just explode before your eyes or come down supersonic.
40
86000
2000
有时，火箭会在你眼前爆炸，或者以超音速的速度扎下来。
01:46
(Laughter)
41
88000
2000
（笑声）
01:48
To take this shot, I do what I often do,
42
90000
2000
为了拍这镜头，我和往常一样，
01:50
which is go way beyond the pads where none of the other spectators are.
43
92000
2000
远离发射台，找个没有其他观众的地方。
01:52
And if we can run the video, I'll show you what it took
44
94000
2000
如果我们播放这段视频，我会展示给大家是如何拍摄这些“梦工厂”般的镜头的。
01:54
to get this DreamWorks shot.
45
96000
3000
如果我们播放这段视频，我会展示给大家是如何拍摄这些“梦工厂”般的镜头的。
01:58
(Video) Voices: Woohoo! Yeah. Nice.
46
100000
2000
视频：声音：Yeah.不错。
02:00
Steve Jurvetson: This is rare. Here's where they realized the computer's failed.
47
102000
3000
Steve Jurvetson: 这是罕见的。这里他们意识到计算机出故障了。
02:03
They're yelling deploy. Voices: Oh shit.
48
105000
2000
他们大叫着. 声音：糟糕。
02:05
SJ: This is when they realize everything on board's gone haywire.
49
107000
2000
SJ：这时他们意识到火箭搭载的设备都失控了。
02:07
Voices: It's going ballistic. Oh shit.
50
109000
1000
声音：它发威失控了。糟糕。
02:08
SJ: And I'll just be quiet.
51
110000
1000
SJ：我只是不出声。
02:09
Voices: No.
52
111000
3000
声音：不。
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
SJ：我在那里，拍下了整个过程。
02:22
Things often go wrong.
55
124000
2000
事情常会出错。
02:24
Some people watch this event because of a NASCAR-like fascination
56
126000
2000
有些人观看这类事故是因为着迷于类似于NASCAR（全国运动汽车竞赛协会）
02:26
with things bumping and grinding. Burning the parachute as it fell --
57
128000
2000
看火箭的撞地，粉碎，落下时降落伞燃烧
02:28
that was last weekend.
58
130000
2000
这是在上周末。
02:30
This guy went up, went supersonic, ripped the fin can off --
59
132000
2000
这枚火箭飞上天，突破音速，扯掉了尾翼，
02:32
yard sale in the sky --
60
134000
2000
（碎片四散在空中）像开拍卖会一样，
02:34
and a burning metal hunk coming back.
61
136000
2000
燃烧的金属碎片落下。
02:36
These things would drop down from above all through the weekend
62
138000
2000
整个周末都会有这类东西掉下来
02:38
of rocket launch after rocket launch after rocket launch.
63
140000
2000
一遍遍的火箭发射，火箭发射，火箭发射。
02:40
It's a cadence you can't quite imagine.
64
142000
2000
节奏之快是你不能想象的。
02:42
And in many ways, I try to capture the mishaps;
65
144000
2000
很多方面，我设法捕捉到这类事故
02:44
it's the challenge in photography when these things all take place
66
146000
2000
从摄影方面来讲，拍下这些瞬间发生的事情确实是个挑战。
02:46
in a fraction of a second.
67
148000
2000
从摄影方面来讲，拍下这些瞬间发生的事情确实是个挑战。
02:48
Why do they do it? It's for things like this:
68
150000
2000
他们为什么干这个？是为了这类东西：
02:50
Gene from Alabama drives out there
69
152000
2000
从阿拉巴马州来的Gene驱车来到这里
02:52
with this rocket that he's built with X-ray sensors, video cameras,
70
154000
3000
带着他造的火箭，上面装有X射线传感器，视频摄像头，
02:55
festooned with electronics, and he succeeds getting to 100,000 feet,
71
157000
3000
装有电子设备，成功的飞到10万英尺(30公里)高度，
02:58
leaving the atmosphere, seeing a thin blue line of space.
72
160000
2000
飞离了大气层，看到了一线蓝色的太空。
03:00
It is this breathtaking image --
73
162000
2000
这是激动人心的图片
03:02
success, of course -- that motivates us
74
164000
2000
成功，当然， 激励着我们。
03:04
and motivates kids to follow and understand rocket science:
75
166000
3000
同时激励孩子们接受和理解火箭科学，
03:07
to understand the importance of physics and math
76
169000
2000
了解到物理和数学的重要性，
03:09
and, in many ways, to sort of have that awe at exploration
77
171000
2000
很多方面多少对探索未知前沿产生敬畏。
03:11
of the frontiers of the unknown.
78
173000
2000
很多方面多少对探索未知前沿产生敬畏。
03:13
Thank you.
79
175000
2000
谢谢。
03:15
(Applause)

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.
