这台平板电脑和
我戴的这个虚拟现实头盔
我戴的这个虚拟现实头盔
00:19
are going to completely
revolutionize science education.

将如何彻底改革科学教育。
00:24
And I'm also going to show you
3
12100
1795
我还会给大家展示
00:25
how it can make any science teacher
more than twice as effective.
more than twice as effective.

它如何让所有科学教师的
教学效率翻倍。
教学效率翻倍。
00:31
But before I show you
how all of this is possible,
how all of this is possible,
5
19124
3464
但是在我向大家展示这些之前，
00:34
let's talk briefly about why improving
the quality of science education
the quality of science education
6
22612
5539
我们先来简要谈一谈为什么
提高科学教育质量
提高科学教育质量
00:40
is so vitally important.
7
28175
2440
是如此的重要。
00:43
If you think about it,
8
31513
1161
你仔细想一想，
00:44
the world is growing incredibly fast.
9
32698
2275
当今世界发展速度快得惊人。
00:47
And with that growth comes
a whole list of growing challenges,
a whole list of growing challenges,
10
35322
3885
但伴随着发展，
一系列的挑战也层出不穷
一系列的挑战也层出不穷
00:51
challenges such as dealing
with global warming,
with global warming,
11
39231
3013
这些挑战包括应对全球变暖，
00:54
solving starvation and water shortages
12
42268
2363
解决温饱和水资源短缺问题，
00:56
and curing diseases,
13
44655
1452
还要治疗疾病，
00:58
to name just a few.
14
46131
1525
这些只是几个例子。
01:00
And who, exactly, is going to help us
solve all of these great challenges?
solve all of these great challenges?
15
48402
5480
那么，究竟谁能帮助我们
应对这些巨大的挑战呢？
应对这些巨大的挑战呢？
01:06
Well, to a very last degree,
it is these young students.
it is these young students.
16
54733
3437
其实很大程度上，
这些人会是年轻的学生们。
这些人会是年轻的学生们。
01:10
This is the next generation
of young, bright scientists.
of young, bright scientists.
17
58194
3842
这些人是下一代年轻聪慧的科学家。
01:14
And in many ways, we all rely on them
18
62060
3020
在很多方面，我们都得靠他们
01:17
for coming up with new, great innovations
19
65104
2802
提出崭新的、伟大的创新观点，
01:19
to help us solve all
these challenges ahead of us.
these challenges ahead of us.
20
67930
3711
来帮助我们解决人类面临的种种挑战。
01:24
And so a couple of years back,
21
72708
1951
就在几年之前，
01:26
my cofounder and I were teaching
university students just like these,
university students just like these,
22
74683
4359
我和我的合伙人
正是这样教导着大学生们，
正是这样教导着大学生们，
01:31
only the students we were teaching
looked a little bit more like this here.
looked a little bit more like this here.
23
79066
5114
只是我们所教的这些学生
看上去更像是这样。
看上去更像是这样。
01:36
(Laughter)
24
84204
1064
（笑声）
01:37
And yes, this is really
the reality out there
the reality out there
25
85292
2838
是的，这真的是目前的现状，
01:40
in way too many universities
around the world:
around the world:
26
88154
3525
在世界上太多的大学都是如此：
01:43
students that are bored, disengaged
27
91703
2653
学生们很无聊，很散漫，
01:46
and sometimes not even sure
why they're learning about a topic
why they're learning about a topic
28
94380
3605
有时甚至不确定最初
为什么要去学某项东西。
为什么要去学某项东西。
01:50
in the first place.
29
98009
1199
01:51
So we started looking around for new,
innovative teaching methods,
innovative teaching methods,
30
99763
4334
所以我们开始探索
新的创新性教学方式，
新的创新性教学方式，
01:56
but what we found was quite disappointing.
31
104121
2823
但是得到的结果却很令人失望。
01:58
We saw that books were being
turned into e-books,
turned into e-books,
32
106968
3665
只见纸质书慢慢转变为电子书，
02:03
blackboards were being turned
into YouTube videos
into YouTube videos
33
111495
3016
黑板渐渐被YouTube视频替代，
02:06
and lecture hall monologues
were being turned into MOOCs --
were being turned into MOOCs --
34
114535
3144
讲堂里的讲座变成了慕课——
02:09
massive online open courses.
35
117703
2301
大规模的网络公开课。
02:12
And if you think about it,
36
120694
1247
如果你仔细想一想，
02:13
all we're really doing here
is taking the same content
is taking the same content
37
121965
3583
我们所做的一切就是把
相同的内容，
相同的内容，
02:17
and the same format,
38
125572
1548
还有相同的格式，
02:19
and bringing it out to more students --
39
127144
2926
传递给更多的学生——
02:22
which is great, don't get me
wrong, that is really great --
wrong, that is really great --
40
130565
2838
其实这挺好的，别误会，
我觉得这非常好——
我觉得这非常好——
02:25
but the teaching method
is still more or less the same,
is still more or less the same,
41
133427
3627
但是教学方式或多或少都是相同的，
02:29
no real innovation there.
42
137078
2296
这一点没有真正的创新。
02:31
So we started looking elsewhere.
43
139863
2019
所以我们开始探索新思路。
02:33
What we found was that flight simulators
had been proven over and over again
had been proven over and over again
44
141906
4627
我们发现的是，
当与真正的飞行训练相结合时，
当与真正的飞行训练相结合时，
02:38
to be far more effective
45
146557
1467
02:40
when used in combination with real,
in-flight training to train the pilots.
in-flight training to train the pilots.
46
148048
5266
飞行模拟器在训练飞行员方面
一直以来都非常有效。
一直以来都非常有效。
02:45
And so we thought to ourselves:
47
153338
1625
于是我们就思考：
02:47
Why not just apply that to science?
48
155532
2337
何不将其应用到科学领域呢？
02:49
Why not build a virtual
laboratory simulator?
laboratory simulator?
49
157893
4551
为什么不建一台
虚拟的实验室模拟器呢？
虚拟的实验室模拟器呢？
02:55
Well, we did it.
50
163563
1248
我们就这么做了。
02:56
We basically set out to create
51
164835
1818
我们开始创造
02:58
a fully simulated, one-to-one,
virtual reality laboratory simulator,
virtual reality laboratory simulator,
52
166677
5615
一个完全模拟的，一对一的
虚拟现实的实验室模拟器，
虚拟现实的实验室模拟器，
03:04
where the students
could perform experiments
could perform experiments
53
172316
2197
在这里学生们可以做实验，
03:06
with mathematical equations
54
174537
1910
让数学公式来模拟
现实实验室中会发生的事情。
现实实验室中会发生的事情。
03:08
that would simulate what would
happen in a real-world lab.
happen in a real-world lab.
55
176471
3219
03:11
But not just simple simulations --
56
179714
1679
但是又不只是简单的模拟，
03:13
we would also create advanced simulations
57
181417
2066
我们也可以与
麻省理工这样的顶尖大学合作
麻省理工这样的顶尖大学合作
03:15
with top universities like MIT,
58
183507
1924
创造更高级的模拟效果，
03:17
to bring out cutting-edge cancer
research to these students.
research to these students.
59
185455
4369
把顶尖的癌症治疗成果分享给学生。
03:22
And suddenly, the universities
could save millions of dollars
could save millions of dollars
60
190520
2883
这样，大学就可以一下子省下上百万美金，
03:25
by letting the students
perform virtual experiments
perform virtual experiments
61
193427
2930
只需让学生们在进真正实验室之前
03:28
before they go into the real laboratory.
62
196381
3112
先做一遍虚拟的实验。
03:32
And not only that; now,
they could also understand --
they could also understand --
63
200303
2532
不仅如此；
现在他们同样可以搞懂
现在他们同样可以搞懂
03:34
even on a molecular level
inside the machine --
inside the machine --
64
202859
2433
机器内部正在发生着什么，
03:37
what is happening to the machines.
65
205316
2676
即使小至分子水平。
03:40
And then they could suddenly perform
66
208016
1899
他们也可以一下子
03:41
dangerous experiments in the labs as well.
67
209939
2628
就能在实验室里做更危险的实验了。
03:44
For instance also here,
68
212591
1486
比如说这里，
03:46
learning about salmonella bacteria,
which is an important topic
which is an important topic
69
214101
3612
我们可以教授一个重要内容：
沙门氏菌，
沙门氏菌，
03:49
that many schools cannot teach
for good safety reasons.
for good safety reasons.
70
217737
3971
目前很多学校基于安全考虑是
不开设这门课程的。
不开设这门课程的。
03:54
And we, of course, quiz the students
71
222315
1737
我们当然也可以给学生小测，
03:56
and then give the teachers
a full dashboard,
a full dashboard,
72
224076
2405
然后给老师们一个完整的反馈，
03:58
so they fully understand
where the students are at.
where the students are at.
73
226505
2926
这样他们可以清晰地了解
学生们学得如何。
学生们学得如何。
04:02
But we didn't stop there,
74
230134
1208
但是我们没有就此停止，
04:03
because we had seen just
how important meaning is
how important meaning is
75
231366
2325
因为我们才刚看到
学生在课程中的投入度
学生在课程中的投入度
04:05
for the students' engagement in the class.
76
233715
2286
有多么深远的意义。
04:08
So we brought in game designers
77
236025
1722
于是我们找来游戏设计师，
04:09
to create fun and engaging stories.
78
237771
2881
写一些有趣、有吸引力的故事。
04:12
For instance, here in this case,
79
240676
1834
比如在这个例子中，
04:14
where the students have to solve
a mysterious CSI murder case
a mysterious CSI murder case
80
242534
4123
学生们需要运用核心科学知识
04:18
using their core science skills.
81
246681
2694
解决神秘的犯罪现场谋杀案。
04:23
And the feedback we got
when we launched all of this
when we launched all of this
82
251861
2444
我们在发布这些之后
所得到的反馈，
所得到的反馈，
04:26
was quite overwhelmingly positive.
83
254329
1952
简直是铺天盖地的好评。
04:28
Here we have 300 students,
84
256305
1803
这里的300名学生，
04:30
all passionately solving CSI murder cases
85
258132
2715
都无比投入地解决谋杀案件，
04:32
while learning core science skills.
86
260871
1865
与此同时还学习了核心科学技能。
04:34
And what I love the most about this
87
262760
2245
我对此最爱的一点
04:37
is really when the students
come up to me sometimes afterwards,
come up to me sometimes afterwards,
88
265029
3644
就是有时候学生们
在玩过这些之后找到我，
在玩过这些之后找到我，
04:40
all surprised and a little confused,
89
268697
2115
很惊讶、很疑惑地看着我说：
04:42
and say, "I just spent two hours
in this virtual lab,
in this virtual lab,
90
270836
4703
“我刚刚在虚拟实验室里
待了两个钟头，
待了两个钟头，
04:48
and ... and I didn't check Facebook."
91
276432
2179
而且……我一直都没刷Facebook。”
04:50
(Laughter)
92
278635
1329
（笑声）
04:51
That's how engaging and immersive
this really is for the students.
this really is for the students.
93
279988
4651
对于学生来说，
它就是如此迷人、令人沉浸其中。
它就是如此迷人、令人沉浸其中。
04:56
And so, to investigate
whether this really worked,
whether this really worked,
94
284663
2820
于是为了探究这是否有实效，
04:59
a learning psychologist
did a study with 160 students --
did a study with 160 students --
95
287507
4403
一个教育心理学家
对160名学生做了研究——
对160名学生做了研究——
05:03
that was from Stanford University
and Technical University of Denmark.
and Technical University of Denmark.
96
291934
4246
这些学生们来自斯坦福大学
和丹麦技术大学。
和丹麦技术大学。
05:08
And what they did is split
the students into two groups.
the students into two groups.
97
296204
3532
他们所做的是，
把学生们分成两个小组。
把学生们分成两个小组。
05:11
One group would only use
the virtual laboratory simulations,
the virtual laboratory simulations,
98
299760
4251
一个小组只使用
虚拟的模拟实验室，
虚拟的模拟实验室，
05:16
the other group would only use
traditional teaching methods,
traditional teaching methods,
99
304035
3700
另外一组只使用
传统的教学方式，
传统的教学方式，
05:19
and they had the same amount of time.
100
307759
1915
然后给他们相同的时间。
05:22
Then, interestingly,
101
310801
1152
十分有趣的是，
05:23
they gave the students a test
before and after the experiment,
before and after the experiment,
102
311977
3667
他们在实验之前和之后
都对学生进行测试，
都对学生进行测试，
05:27
so they could clearly measure
the learning impact of the students.
the learning impact of the students.
103
315668
4353
这样他们就可以量化
教学过程对学生的影响。
教学过程对学生的影响。
05:32
And what they found
104
320045
1168
他们发现，
05:33
was a surprisingly high 76 percent
increase in the learning effectiveness
increase in the learning effectiveness
105
321237
5801
虚拟实验室方法相比传统教学方法，
05:39
when using virtual laboratories
over traditional teaching methods.
over traditional teaching methods.
106
327062
4844
教学有效性提高了惊人的76%！
05:44
But even more interestingly,
107
332349
1485
但是更有趣的是，
05:45
the second part of this study investigated
108
333858
3214
这个研究的第二部分调查了
05:49
what the teacher's impact
was on the learning.
was on the learning.
109
337096
2904
教师对教学过程的影响。
05:52
And what they found
110
340024
1151
他们发现，
05:53
was that when you combined
the virtual laboratories
the virtual laboratories
111
341199
2662
当你把虚拟实验室方法
05:55
with teacher-led coaching and mentoring,
112
343885
2604
与教师的教学辅导相结合，
05:58
then we saw a total 101 percent
increase in the learning effectiveness,
increase in the learning effectiveness,
113
346513
5816
我们可以看到101%的
教学有效性增长，
教学有效性增长，
06:04
which effectively doubles
the science teacher's impact
the science teacher's impact
114
352353
4432
这从效率上相当于
在相同的一段时间里
在相同的一段时间里
06:08
with the same amount of time spent.
115
356809
2358
把科学教师的影响翻了一番。
06:13
So a couple of months back,
116
361784
2710
几个月前，
06:16
we started asking ourselves --
117
364518
1513
我们开始问自己——
06:18
we have a wonderful team now
of learning psychologists
of learning psychologists
118
366055
2547
我们有一个超棒的团队，
有教育心理学家，
有教育心理学家，
06:20
and teachers and scientists
and game developers --
and game developers --
119
368626
2356
有教师和科学家，
还有游戏设计师——
还有游戏设计师——
06:23
and we started asking ourselves:
120
371006
1541
我们就在扪心自问：
06:24
How can we keep ourselves to our promise
121
372571
2595
我们怎么才能信守承诺，
06:27
of constantly reimagining education?
122
375190
2964
不断地重构教育方式？
06:30
And today, I am really excited
to be presenting what we came up with
to be presenting what we came up with
123
378178
5101
而今天，能向大家展示我们的研究成果，
我感到非常兴奋，
我感到非常兴奋，
06:35
and have been working
incredibly hard to create.
incredibly hard to create.
124
383303
2904
这是我们花了很大的努力创造出来的。
06:40
I will explain briefly what this is.
125
388228
2633
我简单介绍一下这个是什么。
06:42
Basically, I take my mobile phone --
126
390885
2736
基本上，我只用我的手机——
06:45
most students already
have these, smartphones --
have these, smartphones --
127
393645
2706
大多数学生都有这种智能手机，
06:48
and I plug it into this virtual-reality
headset, a low-cost headset.
headset, a low-cost headset.
128
396375
4524
然后把它接到这个
低成本的虚拟现实头盔上。
低成本的虚拟现实头盔上。
06:52
And now what I can effectively do is,
129
400923
1969
那么现在我完全可以做到的就是，
06:54
I can literally step
into this virtual world.
into this virtual world.
130
402916
3150
我可以直接走进这个虚拟世界里。
06:58
We'll have some of you
in the audience also get to try this,
in the audience also get to try this,
131
406090
3084
我们等下会让一些观众来尝试，
07:01
because it is really something
that you have to try
that you have to try
132
409198
3156
因为这个东西你们必须得尝试过，
07:04
to fully feel how immersive it really is.
133
412378
2295
才能体会到沉浸式体验的强大。
07:06
It literally feels like I just stepped
inside this virtual lab.
inside this virtual lab.
134
414697
3777
这感觉上就好像
我直接踏进了这个虚拟实验室！
我直接踏进了这个虚拟实验室！
07:10
Do you see me up on the screen?
135
418498
1503
你们在屏幕上看到我了吗？
07:12
Audience: Yes.

07:14
So basically, I have just
turned my mobile phone
turned my mobile phone
138
422827
2898
那么，我刚刚把我的手机变成了
07:17
into a fully simulated, million-dollar
Ivy League laboratory
Ivy League laboratory
139
425749
3664
一个全模拟的，
百万美元级的常青藤大学实验室，

140
429437
2825
里面满是我可以操作的神奇仪器。
07:24
I can, for instance, pick up the pipette
and do experiments with it.
and do experiments with it.
141
432286
3373
比如说，我可以用移液管来做实验，
07:27
I have my E-Ggel, my PCR
and -- oh, look there,
and -- oh, look there,
142
435683
2420
还有有电泳仪、
PCR仪······哦，看那边，
PCR仪······哦，看那边，
07:30
I have my next-generation
sequencing machine,
sequencing machine,
143
438127
2521
那是下一代的基因测序仪，
07:32
and there I even have
my electron microscope.
my electron microscope.
144
440672
3498
这里还有一台电子显微镜。
07:36
I mean, who's carrying around
an electron microscope in their pocket?
an electron microscope in their pocket?
145
444194
3430
我在想，谁会在裤子口袋里
放一台电子显微镜呢？
放一台电子显微镜呢？
07:39
And here I have my machine,
146
447648
1872
这里有一台电脑，
07:41
I can do different experiments
on the machine.
on the machine.
147
449544
2170
我可以在电脑上做各种实验。
07:43
And over here I have the door,
148
451738
1454
这里还有扇门，
07:45
I can go into other experiments,
149
453216
2368
我可以到其它的实验室，
07:47
I can perform in the laboratories.
150
455608
1933
去做其它的实验。
07:49
And here, I have my learning tablet.
151
457565
2206
在这里我有一台学习电脑。
07:51
This is an intelligent tablet
152
459795
1454
这是一台智能的平板电脑，
07:53
that allows me to read
about relevant theory.
about relevant theory.
153
461273
2848
可以让我阅读相关的理论知识。
07:56
As you can see, I can interact with it.
154
464145
2302
你们可以看到，我可以与之互动。
07:58
I can watch videos and see
content that is relevant
content that is relevant
155
466471
3894
我可以看视频，学习一些
08:02
to the experiment
that I'm performing right now.
that I'm performing right now.
156
470389
2865
跟我正在做的实验
密切相关的东西。
密切相关的东西。
08:06
Then over here, I have Marie.
157
474074
1403
然后来到这儿，这位是玛丽。
08:07
She is my teacher --
my lab assistant --
my lab assistant --
158
475501
3519
她是我的老师，
也是我在实验室的助手——
也是我在实验室的助手——
08:11
and what she does is guides me
through this whole laboratory.
through this whole laboratory.
159
479044
3177
她所做的就是引导我
使用整个实验室的仪器。
使用整个实验室的仪器。
08:14
And very soon,
160
482245
1159
很快地，
08:15
the teachers will be able
to literally teleport themselves
to literally teleport themselves
161
483428
2968
老师们就真正可以传送到
08:18
into this virtual world
that I'm in right now
that I'm in right now
162
486420
2559
我所在的这个虚拟世界里，
08:21
and help me, guide me,
through this whole experiment.
through this whole experiment.
163
489003
3230
然后帮助我，引导我
完成整个实验。
完成整个实验。
08:24
And now before I finalize this,
164
492257
2310
现在，在我结束之前，
08:26
I want to show you
an even cooler thing, I think --
an even cooler thing, I think --
165
494591
2968
我想给你们看一个更酷炫的东西，
08:29
something you cannot
even do in real laboratories.
even do in real laboratories.
166
497583
3036
在真实实验室里根本做不到的事。
08:32
This is a PCR machine.
167
500643
1238
这是一台PCR仪。
08:33
I'm now going to start this experiment.
168
501905
2480
我要开始做实验了。
08:36
And what I just did is literally
shrunk myself a million times
shrunk myself a million times
169
504409
4233
我刚刚做的就是
把自己缩小了一百万倍，
把自己缩小了一百万倍，
08:40
into the size of a molecule --
170
508666
1559
变成分子的大小——
08:42
and it really feels like it,
you have to try this.
you have to try this.
171
510249
2349
感觉就像是这样，你们必须得试试！
08:44
So now it feels like
I'm standing inside the machine
I'm standing inside the machine
172
512622
2603
现在感觉像是我站在机器里，
08:47
and I'm seeing all the DNA,
and I see the molecules.
and I see the molecules.
173
515249
2593
我看到这里所有的DNA，还有分子，
08:49
I see the polymerase
and the enzymes and so forth.
and the enzymes and so forth.
174
517866
3603
我看到聚合酶还有生化酶等等。
08:53
And I can see how in this case,
175
521493
1603
在这种情况下，
08:55
DNA is being replicated millions of times,
176
523120
3077
我看到DNA是
如何被复制上百万次的，
如何被复制上百万次的，
08:58
just like it's happening
inside your body right now.
inside your body right now.
177
526221
2833
就像现在你的身体里正在进行的那样。
09:01
And I can really feel and understand
how all of this works.
how all of this works.
178
529078
4127
我真的可以感受、理解这些原理了。
09:06
Now, I hope that gives you
a little bit of a sense
a little bit of a sense
179
534219
3294
我希望这些能够给你们一点概念，
09:09
of the possibilities
in these new teaching methods.
in these new teaching methods.
180
537537
4126
就是这种全新教学方式的可能性。
09:16
And I want to also emphasize
181
544230
1342
此外我还想强调一下，
09:17
that everything you just saw
also works on iPads and laptops
also works on iPads and laptops
182
545596
3691
刚刚你们看到的一切
也可以在iPad和笔记本电脑上实现，
也可以在iPad和笔记本电脑上实现，
09:21
without the headsets.
183
549311
1171
而完全不需要这个头盔。
09:22
I say that for a very important reason.
184
550506
2364
我讲这个是有很重要原因的。
09:25
In order for us to really
empower and inspire
empower and inspire
185
553394
3485
为了让我们真正地
激发、启迪下一代的科学家，
09:28
the next generation of scientists,
186
556903
2168
09:31
we really need teachers
to drive the adoption
to drive the adoption
187
559095
3524
我们迫切需要教师们推动
09:34
of new technologies in the classroom.
188
562643
2575
这些课堂新科技的推广。
09:38
And so in many ways,
189
566542
1878
从很多角度来看，
09:40
I believe that the next big,
quantum leap in science education
quantum leap in science education
190
568444
4355
我相信科学教育的
下一个伟大的、质的飞跃，
下一个伟大的、质的飞跃，
09:44
lies no longer with the technology,
191
572823
2309
已不在于科技发展本身，
09:47
but rather with the teachers' decision
192
575156
1881
而在于教师们的作为，
09:49
to push forward and adopt
these technologies
these technologies
193
577061
3205
将这些新科技推广及采用，
09:52
inside the classrooms.
194
580290
1747
带到课堂上去。
09:54
And so it is our hope that more
universities and schools and teachers
universities and schools and teachers
195
582061
3837
我们的期望是让更多的
大学、学校和老师，
大学、学校和老师，
09:57
will collaborate with technology companies
196
585922
2865
都与科技公司合作，
10:00
to realize this full potential.
197
588811
2524
来实现它全部的潜能。
10:04
And so,
198
592989
1445
讲到这里，
10:06
lastly, I'd like to leave you
with a little story
with a little story
199
594458
2833
最后，我想告诉大家一个
10:09
that really inspires me.
200
597315
1562
特别鼓舞我的小故事。
10:10
And that is the story of Jack Andraka.
201
598901
2421
是关于杰克·安德拉卡的故事。
10:13
Some of you might already know him.
202
601346
1762
你们有些人可能知道他。
10:15
Jack invented a new, groundbreaking
low-cost test for pancreatic cancer
low-cost test for pancreatic cancer
203
603132
6992
杰克研究出了一种全新的、突破性的、
低成本的胰腺癌检测法，
低成本的胰腺癌检测法，
10:22
at the age 15.
204
610148
2421
那时他只有15岁。
10:25
And when Jack shares his story
of how he did this huge breakthrough,
of how he did this huge breakthrough,
205
613758
3739
当杰克分享自己
做出这个伟大突破的经历时，
做出这个伟大突破的经历时，
10:29
he also explains that one thing
almost prevented him
almost prevented him
206
617521
3825
他也讲述了一件
几乎阻止了他取得这项突破的事。
10:33
from making this breakthrough.
207
621370
1793
10:35
And that was that he did not
have access to real laboratories,
have access to real laboratories,
208
623543
5060
那就是他没办法进入
真正的实验室里，
真正的实验室里，
10:40
because he was too inexperienced
209
628627
2529
因为他经验非常不足，
10:43
to be allowed in.
210
631180
1441
不被允许进入。
10:45
Now, imagine if we could bring
211
633853
2202
那么想象一下，如果我们能把
10:48
Ivy League, million-dollar
virtual laboratories
virtual laboratories
212
636079
3269
常青藤名校，百万美元级的虚拟实验室
10:51
out to all these students just like Jack,
213
639372
2071
带给像杰克一样的所有学生，
10:53
all over the world,
214
641467
1607
在全世界范围推广，
10:55
and give them the latest, greatest,
most fancy machines you can imagine
most fancy machines you can imagine
215
643098
3556
把你能想象到的
最新、最棒、最花哨的仪器都给他们，
最新、最棒、最花哨的仪器都给他们，
10:58
that would quite literally
make any scientist in here
make any scientist in here
216
646678
2546
那就真的会让这里的所有科学家
11:01
jump up and down out of pure excitement.
217
649248
2473
都兴奋得活蹦乱跳了。
11:03
And then imagine how that
would empower and inspire
would empower and inspire
218
651745
4610
再想象一下，
这样定会激励和启迪
这样定会激励和启迪
11:08
a whole new generation
of young and bright scientists,
of young and bright scientists,
219
656379
4179
全新一代的年轻聪慧的科学家，
11:12
ready to innovate and change the world.
220
660582
3203
准备好做出创新，改变世界。
11:16
Thank you very much.
