ABOUT THE SPEAKER
Michael Nielsen - Physicist
A physicist turned writer, Michael Nielsen believes online communication and collaboration tools are revolutionizing the way we make scientific discoveries.

Why you should listen

A Fulbright scholar, Michael Nielsen not only made significant research contributions in the field of quantum physics, but also co-wrote the popular Quantum Computation and Quantum Information. He left academia to focus his research on “open science,” and recently published Reinventing Discovery: The New Era of Networked Science -- a book that discusses the Internet’s ability to “amplify our collective intelligence” and the cultural obstacles of the scientific community impeding this dramatic shift.

Well, good afternoon, everybody.

00:15
Thank you all very much
for coming along today.
1
2136
2849
00:18
I'd like to begin my talk with a story.
2
5009
3586
00:21
It's a story that begins,
but does not end,
3
8619
2473
00:24
with a mathematician named Tim Gowers.
4
11116
2641
00:27
Gowers is one of the world's most
renowned mathematicians.
5
14401
3224
00:30
He's a professor at Cambridge University
6
17649
2580
00:33
and a recipient of the Fields Medal,
7
20253
2289
00:35
often called the Nobel Prize
of mathematics.
8
22566
2740
00:39
Gowers is also a blogger,
9
26369
2341
00:42
and in January of 2009, he used his blog
to pose a very striking question:
10
29602
6105
00:49
Is massively collaborative
mathematics possible?
11
36588
4594
00:55
So what he was proposing in this post
12
42321
2883
00:58
was to use his blog to attack a difficult
unsolved mathematical problem --
13
45228
4916
01:03
a problem which he said
he would "love to solve" --
14
50168
2848
01:06
completely in the open,
15
53040
1472
01:07
using his blog to post his ideas
and his partial progress.
16
54536
4409
01:13
What's more, he issued an open invitation,
17
60096
3374
01:16
inviting anybody in the world who thought
that they had an idea to contribute
18
63494
4563
01:21
to post their idea
in the comment section of the blog.
19
68081
4184
01:26
His hope was that by combining
the ideas of many minds,
20
73335
4027
01:30
he could make easy work
of his hard mathematical problem.
21
77386
3020
01:33
He called this experiment
the Polymath Project.
22
80954
2602
01:37
Well, the Polymath Project
got off to a slow start.
23
84914
2430
01:40
In the first seven hours,
nobody posted any comments.
24
87368
2596
01:43
But then, a mathematician
from the University of British Columbia
25
90537
3513
01:47
named Jozsef Solymosi
26
94074
1547
01:48
posted a short comment.
27
95645
1685
01:50
And this seemed to break the ice,
because a few minutes later,
28
97354
2989
01:53
a high school teacher named
Jason Dyer posted a suggestion.
29
100367
3642
01:57
And a few minutes after that,
30
104033
1725
01:58
another mathematician named
Terence Tao, also a Fields medalist,
31
105782
3755
02:02
posted an idea.
32
109561
1639
02:04
And things really started
to move quickly at this point.
33
111224
3343
02:07
Over the next 37 days,
34
114591
2097
02:09
27 different people would post
800 substantive comments
35
116712
5099
02:14
containing 170,000 words.
36
121835
3992
02:19
I was not a serious participant,
but I was following along closely
37
126414
3157
02:22
from the start,
38
129595
1152
02:23
and it was just amazing.
39
130771
1662
02:25
The speed with which an idea
would be tentatively proposed
40
132457
2878
02:28
and then really rapidly developed
by other people and improved,
41
135359
3875
02:32
sometimes discarded --
42
139258
1174
02:33
it was just amazing.
43
140456
1332
02:35
Gowers described the process
44
142261
2272
02:37
as being to ordinary research
"as driving is to pushing a car."
45
144557
4790
02:42
(Laughter)
46
149371
1223
02:44
At the end of the 37 days,
47
151396
2426
02:46
Gowers used his blog to announce
that they had solved the core problem;
48
153846
3863
02:50
in fact, they had solved a harder
generalization of the problem.
49
157733
3501
02:54
The Polymath Project had succeeded.
50
161258
2155
02:57
So what the Polymath Project
suggests, at least to me,
51
164424
3343
03:00
is that we can use
the internet to build tools
52
167791
4129
03:04
that actually expand our ability
53
171944
2792
03:07
to solve the most challenging
intellectual problems.
54
174760
3495
03:12
Or, to put it in another way:
55
179523
1755
03:14
we can build tools which actively amplify
our collective intelligence
56
181302
4653
03:18
in much the same way as, for millennia,
we've used physical tools
57
185979
4484
03:23
to amplify our strength.
58
190487
1781
03:27
OK?
59
194469
1154
03:28
So what I'd like to talk about today,
or what I'd like to explore today,
60
195647
3613
03:32
is what this means for science.
61
199284
2458
03:34
It's much more important than just solving
a single mathematical problem.
62
201766
3735
03:38
It means an expansion in the range
of scientific problems
63
205525
3449
03:41
we can hope to attack at all.
64
208998
2199
03:44
It means, potentially, an acceleration
in the rate of scientific discovery.
65
211221
4084
03:48
It means a change in the way
we construct knowledge itself.
66
215329
3357
03:52
So, before I get too overexcited, however,
67
219471
2883
03:55
I would like to talk
about some of the challenges,
68
222378
2966
03:58
some of the problems.
69
225368
1156
03:59
Particularly, I'd like to describe
a failure of this approach.
70
226548
3625
04:03
It occurred in 2005, or started in 2005.
71
230788
3536
04:07
A grad student at Caltech named
John Stockton had a very good idea
72
234348
5368
04:12
for what he called the "Quantum Wiki,"
73
239740
2740
04:15
or "Qwiki" for short.
74
242504
2001
04:17
(Laughter)
75
244529
1141
04:18
OK? It's a great idea.
76
245694
1709
04:20
What he did with the Qwiki was --
77
247427
2980
04:23
the idea of the Qwiki was that it
was going to be a great repository
78
250431
3301
04:26
of human knowledge,
79
253756
1154
04:27
much like Wikipedia.
80
254934
1316
04:29
But instead of being focused
on general knowledge,
81
256274
2854
04:32
it was going to be focused on
specialist knowledge in quantum computing.
82
259152
4382
04:37
It was going be kind of
a supertextbook for the field,
83
264204
2921
04:40
with information about
all the latest research,
84
267149
2470
04:42
about what the big open problems
in the field were,
85
269643
3309
04:45
people's speculation
about how to solve the problems,
86
272976
2551
04:48
and so on.
87
275551
1160
04:50
Like Wikipedia, the intention was
that it would be written by the users,
88
277353
4526
04:54
in this case, by experts
in quantum computing.
89
281903
2737
04:58
I was present at the conference at Caltech
in 2005, when it was announced.
90
285578
4466
05:03
And some of the people who I spoke to
were very skeptical,
91
290532
3067
05:06
but some of the people
were very excited by the idea.
92
293623
3031
05:09
They were impressed by the implementation;
93
296678
2018
05:11
they were impressed by the amount
of initial seed material
94
298720
2736
05:14
which had been put on the site;
95
301480
1485
05:15
and most of all,
they were excited by the vision.
96
302989
2357
05:18
But just because they were excited,
97
305370
1746
05:20
didn't mean they wanted
to take the time themselves to contribute.
98
307140
3188
05:23
They hoped that other people would do so.
99
310843
2575
05:26
And in the end, nobody, essentially,
100
313861
2831
05:29
was really all that interested
in contributing.
101
316716
2572
05:33
If you look today,
except in a few small corners,
102
320324
2991
05:36
the Qwiki is essentially dead.
103
323339
1673
05:38
And, sad to say,
this is quite a common story.
104
325866
2718
05:41
Many scientists, in fields ranging
from genetics to string theory,
105
328608
4058
05:45
have tried to start science wikis
along very similar lines.
106
332690
4047
05:49
And typically, they've failed
for essentially the same reason.
107
336761
3161
05:53
It's not just science wikis, either.
108
340732
1896
05:55
Inspired by Facebook,
109
342652
2047
05:57
many organizations have tried to create
social networks for scientists,
110
344723
4129
06:01
which will connect scientists
to other people with similar interests.
111
348876
4161
06:07
So they can share things like data
or code, their ideas and so on.
112
354856
4216
06:12
Again, it sounds like a good idea.
113
359096
1877
06:13
But if you join one of these sites,
114
360997
2244
06:16
you'll quickly discover
that they're essentially empty.
115
363265
2838
06:19
They're virtual ghost towns.
116
366127
1838
06:22
So what's going on?
What's the problem here?
117
369988
2165
06:25
Why are these promising sites failing?
118
372177
2276
06:27
Well, imagine that you're
an ambitious young scientist.
119
374477
4112
06:31
In fact, I know some of you here
are ambitious young scientists.
120
378613
3451
06:35
Imagine you're
an ambitious young scientist.
121
382088
2473
06:37
You really would like to get a job --
a permanent job, a good job --
122
384585
3959
06:41
doing the work that you love.
123
388568
1562
06:43
But it's incredibly competitive
to get such jobs.
124
390850
2335
06:46
Often, there'll be hundreds of very
highly qualified applicants for positions.
125
393209
4051
06:51
And so you find yourself working
60, 70, 80 hours a week,
126
398912
4209
06:56
doing the one thing that you know
will get you such a job,
127
403145
4485
07:00
and that is writing scientific papers.
128
407654
2262
07:03
You may think that the Qwiki
is a wonderful idea in principle,
129
410770
3141
07:06
but you also know that writing
a single mediocre paper
130
413935
3233
07:10
will do much more for your career
and your job prospects
131
417192
3038
07:13
than a long series of brilliant
contributions to such a site.
132
420254
3872
07:17
So even though you may like the idea
133
424725
1779
07:19
and you may think it will advance
science more quickly,
134
426528
2742
07:22
you find you just can't conceive of it
as being part of your job.
135
429294
3827
07:26
It's not.
136
433145
1233
07:28
The only things which can succeed
in this kind of environment
137
435019
4145
07:32
are projects like the Polymath Project,
138
439188
2443
07:34
which, even though they employ
an unconventional means to an end,
139
441655
4145
07:40
they have an essential
conservatism about them.
140
447221
2310
07:42
The end product of the Polymath Project
was still a scientific paper.
141
449555
3988
07:46
In fact, it was several papers. Right?
142
453567
2287
07:48
So unconventional means,
but conventional ends.
143
455878
3317
07:52
So there's a kind of
conservatism about it.
144
459219
2015
07:54
And don't get me wrong --
the Polymath Project is terrific,
145
461258
3694
07:57
but it is a pity that scientists
can only use tools
146
464976
4379
08:02
which have this kind of
conservative nature.
147
469379
2428
08:05
So let me tell you a story
about an instance
148
472500
2104
08:07
where we moved away
from this conservatism.
149
474628
3119
08:10
It's a rare story where
the conservatism has been broken.
150
477771
3217
08:14
It occurred in the 1990s,
when, as you know,
151
481426
3295
08:17
for the first time, biologists were taking
large amounts of genetic data
152
484745
4433
08:22
to collect in the Human Genome Project.
153
489202
2132
08:24
And there were sites online
154
491846
2346
08:27
which would allow biologists
to upload that data
155
494216
3306
08:30
so it could be shared
with other people around the world
156
497546
2677
08:33
and analyzed by other people.
157
500247
1821
08:35
Probably the best known of these
is the site GenBank,
158
502983
2536
08:38
which some of you may
have heard of or used.
159
505543
2475
08:41
And these sites, like GenBank,
160
508667
1961
08:43
had the problem in common with Qwiki
that scientists -- they're not paid
161
510652
6308
08:49
or rewarded for sharing their data.
162
516984
2606
08:52
It's all about publishing papers.
163
519614
3160
08:55
So there was a considerable reluctance
to actually upload the data.
164
522798
4043
09:00
Yet, everybody could see
that this was silly --
165
527381
2798
09:03
it was obvious that this
was the right thing to do.
166
530203
2534
09:05
But just because it was obvious
167
532761
1550
09:07
didn't mean that people
were actually doing it.
168
534335
2211
09:09
So a meeting was convened
in Bermuda in 1996
169
536570
3041
09:12
of many of the world's leading
molecular biologists.
170
539635
2966
09:15
And they sat and they discussed
the problem for several days,
171
542625
2888
09:18
and they came up with what are now
called the Bermuda Principles,
172
545537
3303
09:21
which state that:
173
548864
1176
09:23
first, once human genetic data
is taken in the lab,
174
550064
4130
09:27
it should be immediately uploaded
175
554218
1934
09:29
to a site like GenBank;
176
556176
1588
09:30
and two, that the data
would be in the public domain.
177
557788
3103
09:34
And these principles were given teeth,
178
561963
1830
09:36
because they were taken by the big
scientific grant agencies --
179
563817
3056
09:39
the US National Institutes of Health,
the UK Wellcome Trust --
180
566897
3251
09:43
and actually baked into policy.
181
570172
1948
09:48
So it meant that if you were a scientist
who wanted to work on the human genome,
182
575147
3844
09:52
you had to agree to abide
by these principles.
183
579015
2224
09:54
And today, I'm very pleased
to say, as a result,
184
581263
2865
09:57
you can go online -- anybody here --
and download the human genome.
185
584152
3877
10:01
So that's a terrific story.
186
588963
1842
10:03
But the human genome
is just a tiny, tiny fraction
187
590829
2719
10:06
of all scientific knowledge.
188
593572
2059
10:09
Even just in other parts of genetics,
189
596727
3056
10:12
there is so much knowledge
that is still locked up.
190
599807
2450
10:15
I spoke with one bioinformatician
191
602281
2078
10:17
who told me that he'd been "sitting
on the genome of an entire species
192
604383
5417
10:22
for more than a year."
193
609824
1411
10:25
An entire species.
194
612193
1531
10:27
And in other parts of science,
195
614779
1583
10:29
it is routine that scientists
hoard their data.
196
616386
3795
10:33
They hoard the computer code
that they write
197
620205
2396
10:35
that could be useful,
potentially, to other people.
198
622625
2419
10:38
They hoard their best ideas.
199
625068
1924
10:40
And they often hoard even
the descriptions of the problems
200
627016
2838
10:42
that they think are most interesting.
201
629878
1912
10:45
And so, what I and other people
in the Open Science movement
202
632347
3300
10:48
would like to do is,
203
635671
1168
10:49
we'd like to change this situation.
204
636863
1846
10:51
We would like to change
the culture of science
205
638733
2481
10:54
so that scientists become
much more strongly motivated
206
641238
2639
10:56
to share all of these
different kinds of knowledge.
207
643901
2643
10:59
We want to change the values
of individual scientists
208
646568
4419
11:04
so they start to see it
as part of their job
209
651011
3497
11:07
to be sharing their data,
to be sharing their code,
210
654532
2530
11:10
to be sharing their best ideas
and their problems.
211
657086
3509
11:14
So, if we can do this,
this kind of change in values,
212
661956
5438
11:20
then we will indeed start to see
individual scientists rewarded
213
667418
4538
11:24
for doing these things;
214
671980
1162
11:26
there will be incentives to do them.
215
673166
1862
11:28
It's a difficult thing to do, however.
216
675463
2714
11:31
We're talking about changing the culture
of entire large parts of science.
217
678758
4941
11:37
But it has happened
before once in history,
218
684400
3090
11:40
right back at the dawn of science.
219
687514
2152
11:43
Galileo, 1609: he points his telescope
up at the sky towards Saturn,
220
690503
6362
11:49
and he sees for the first time in history
221
696889
2601
11:52
what we now know are the rings of Saturn.
222
699514
2091
11:55
Does he tell everybody in the world?
223
702208
1796
11:57
No, he doesn't do that.
224
704028
1255
11:58
He writes down a description, privately,
225
705307
2602
12:00
and then he scrambles the letters
in the description into an anagram,
226
707933
4991
12:05
and he sends that anagram
to several of his astronomer rivals.
227
712948
4279
12:10
(Laughter)
228
717251
1160
12:11
And what this ensures is that,
if they later make the same discovery,
229
718435
6520
12:17
he can reveal the anagram
and get the credit,
230
724979
2486
12:21
but in the meantime, he hasn't given up
any knowledge at all.
231
728411
3211
12:24
And I'm sad to say that he was
not uncommon at the time:
232
731646
3213
12:27
Newton, Huygens, Hooke, Leonardo --
they all used similar devices.
233
734883
4787
12:33
OK?
234
740351
1173
12:35
The printing press had been around
for 150 years by this time.
235
742724
4477
12:40
And yet, there was a great battle
in the 17th and 18th centuries
236
747225
3408
12:43
to change the culture of science,
237
750657
2463
12:46
so that it became expected
that when a scientist made a discovery,
238
753144
3629
12:49
they would reveal it in a journal.
239
756797
2503
12:53
Now, that's great that that change
has happened. It's terrific.
240
760516
3653
12:57
But today, we have new technologies,
241
764193
1930
12:59
we have new opportunities
to share our knowledge in new ways
242
766147
4429
13:03
and the ability to create tools
243
770600
2106
13:05
that actually allow us
to solve problems in entirely new ways.
244
772730
4510
13:11
So we need to have a second
open science revolution.
245
778599
3739
13:15
It is my belief
246
782362
1226
13:16
that any publicly funded science
should be open science.
247
783612
4159
13:21
How can we achieve this change?
248
788750
2368
13:24
Well, if you're a scientist -- and I know
many of you are not scientists,
249
791972
4464
13:29
but if you are a scientist,
250
796460
1349
13:30
then there are things that you can do.
251
797833
2097
13:32
You can get involved
in an open science project,
252
799954
3439
13:36
even if it's just for a small
fraction of your time.
253
803417
3077
13:39
You can find forums online
254
806933
2802
13:42
where you can share
your knowledge in new ways,
255
809759
2553
13:45
ways that allow other people
to build on that knowledge.
256
812336
3172
13:49
You can also, if you're more ambitious,
257
816332
3013
13:52
start an open science project of your own.
258
819369
2475
13:54
If you're really bold,
you may wish to experiment
259
821868
2326
13:57
with entirely new ways of collaborating,
260
824218
2229
13:59
in much the same way
as the Polymath Project did.
261
826471
3064
14:03
But above all, what you should do
is be very generous in giving credit
262
830627
4898
14:08
to those of your colleagues
who are practicing science in the open
263
835549
3582
14:12
and to promote their work.
264
839155
1828
14:14
It is only conservative scientific values
265
841578
3538
14:18
that look down on these activities --
the sharing of data, the blogging,
266
845140
4508
14:22
or using of wikis and so on.
267
849672
1854
14:25
You can reject those conservative values
268
852677
2485
14:28
and engage your scientific
colleagues in conversation
269
855186
2828
14:31
to promote the value
of these new ways of working,
270
858038
3482
14:34
to emphasize that it takes bravery
to do these things,
271
861544
2911
14:37
particularly by young scientists.
272
864479
1992
14:39
It's through such conversation that
the culture of science can be changed.
273
866495
4961
14:45
So if you are not a scientist,
274
872694
2096
14:47
there are also things that you can do.
275
874814
1981
14:50
My belief is that the single most
important thing that we can do
276
877405
4827
14:55
to give impetus to open science
277
882256
3289
14:58
is to create a general awareness
amongst the population
278
885569
4657
15:03
of the issue of open science
and of its critical importance.
279
890250
4329
15:07
If there is that general awareness,
280
894990
2378
15:10
then the scientific community
will inevitably find --
281
897392
3464
15:13
it will be dragged
by the population at large
282
900880
2964
15:16
in the right direction.
283
903868
1299
15:18
There are simple things you can do.
284
905855
1723
15:20
You can talk to your friends
and acquaintances who are scientists
285
907602
3114
15:23
and just ask them
what are they doing to work more openly.
286
910740
2953
15:26
Or you can use your imagination
and your personal power
287
913717
2914
15:29
to raise awareness in other ways.
288
916655
2215
15:32
We're talking about changing
not just what scientists do
289
919414
2741
15:35
but what grant agencies do,
290
922179
1596
15:36
what universities do
and what governments do.
291
923799
2722
15:39
And you can influence all of those things.
292
926545
2567
15:44
Our society faces a fundamental question:
293
931009
3323
15:48
What kinds of knowledge
are we going to expect
294
935403
3116
15:51
and incentivize our scientists to share?
295
938543
3469
15:55
Will we continue
as we have done in the past?
296
942036
2716
15:58
Or will we embrace new kinds of sharing,
297
945184
3516
16:01
which lead to new methods
for solving problems
298
948724
3357
16:05
and an acceleration
in the process of science,
299
952105
2558
16:07
entirely across the board?
300
954687
1701
16:10
My hope is that we will
embrace open science
301
957311
3670
16:14
and really seize
this opportunity that we have
302
961005
3045
16:17
to reinvent discovery itself.
303
964074
2473
16:20
Thank you. (Applause)

ABOUT THE SPEAKER
Michael Nielsen - Physicist
A physicist turned writer, Michael Nielsen believes online communication and collaboration tools are revolutionizing the way we make scientific discoveries.

Why you should listen

A Fulbright scholar, Michael Nielsen not only made significant research contributions in the field of quantum physics, but also co-wrote the popular Quantum Computation and Quantum Information. He left academia to focus his research on “open science,” and recently published Reinventing Discovery: The New Era of Networked Science -- a book that discusses the Internet’s ability to “amplify our collective intelligence” and the cultural obstacles of the scientific community impeding this dramatic shift.
