Throughout history, speculation has spurred beautiful, revolutionary science -- opening our eyes to entirely new universes. "I'm not talking about science that takes baby steps," says Eric Haseltine. "I'm talking about science that takes enormous leaps." In this talk, Haseltine passionately takes us to the edges of intellectual pursuit with two ideas -- one that's already made history, and the other that's digging into one of humanity's biggest questions with admirable ambition (and a healthy dose of skepticism from many).

Tonight, I'm going to share with you
my passion for science.
0
920
3616
00:16
I'm not talking about science
that takes baby steps.
1
4560
3016
00:19
I'm talking about science
that takes enormous leaps.
2
7600
4256
00:23
I'm talking Darwin, I'm talking Einstein,
3
11880
3376
00:27
I'm talking revolutionary science
that turns the world on its head.
4
15280
3600
00:31
In a moment, I'm going to talk
about two ideas that might do this.
5
19440
3400
00:35
I say "might"
6
23800
1216
00:37
because, with revolutionary ideas,
most are flat wrong,
7
25040
2776
00:39
and even those that are right
seldom have the impact
8
27840
2456
00:42
that we want them to have.
9
30320
1696
00:44
To explain why I picked
two ideas in particular,
10
32040
2496
00:46
I'm going to start with a mystery.
11
34560
1680
00:48
1847, Vienna, Austria.
12
36840
3080
00:53
Ignaz Semmelweis was a somber,
compulsively thorough doctor
13
41080
3616
00:56
who ran two maternity clinics.
14
44720
1856
00:58
They were identical except for one thing.
15
46600
2440
01:01
Women were dying of high fevers
soon after giving birth
16
49720
2656
01:04
three times more often
at one of the clinics than at the other.
17
52400
3560
01:08
Trying to figure out
what the difference was that caused this,
18
56600
2936
01:11
Semmelweis looked at everything he could.
19
59560
2016
01:13
Sanitation? No.
20
61600
1736
01:15
Medical procedures? No.
21
63360
2000
01:18
Air flow? No.
22
66000
1920
01:20
The puzzle went unsolved
until he happened to autopsy a doctor
23
68800
3256
01:24
who died of an infected scalpel cut.
24
72080
2000
01:26
The doctor's symptoms were identical
to those of the mothers who were dying.
25
74760
3776
01:30
How was that possible?
26
78560
1376
01:31
How could a male doctor
get the same thing as new mothers?
27
79960
2880
01:35
Semmelweis reconstructed
everything the doctor had done
28
83560
3256
01:38
right before he got sick,
29
86840
1256
01:40
and he discovered
that he'd been autopsying a corpse.
30
88120
4296
01:44
Had something gotten
in his wound that killed him?
31
92440
2800
01:48
With growing excitement,
32
96760
1776
01:50
Semmelweis looked
for any connection he could
33
98560
2816
01:53
between dead bodies in the morgue
and dead mothers in his delivery room,
34
101400
5376
01:58
and he found it.
35
106800
1600
02:01
It turned out that at the hospital
with the high death rate,
36
109320
2856
02:04
but not the others,
37
112200
1776
02:06
doctors delivered babies immediately
after autopsying corpses in the morgue.
38
114000
5136
02:11
Aha! Corpses were contaminating
the doctors' hands
39
119160
3936
02:15
and killing his mothers.
40
123120
1240
02:17
So he ordered the doctors
to sterilize their hands,
41
125240
3055
02:20
and the deaths stopped.
42
128320
2280
02:23
Dr. Ignaz Semmelweis
had discovered infectious disease.
43
131400
4400
02:28
But the doctors of the day
thought he was crazy,
44
136400
3416
02:31
because they knew,
and had for hundreds of years,
45
139840
3496
02:35
that odorous vapors
called miasmas caused disease,
46
143360
5096
02:40
not these hypothetical particles
that you couldn't see.
47
148480
3400
02:44
It took 20 years
for Frenchman Louis Pasteur
48
152880
4176
02:49
to prove that Semmelweis was right.
49
157080
1960
02:51
Pasteur was an agricultural chemist
50
159680
2696
02:54
who tried to figure out
why milk and beer spoiled so often.
51
162400
4176
02:58
He found that bacteria were the culprits.
52
166600
2440
03:02
He also found that bacteria
could kill people in exactly the same way
53
170160
3856
03:06
that Semmelweis's patients were dying.
54
174040
2320
03:09
We now look at what I want
to talk about tonight, in two ideas.
55
177120
4400
03:14
We saw it with Semmelweis,
that he was a revolutionary.
56
182600
2920
03:18
He did it for two reasons.
57
186560
1256
03:19
One, he opened our eyes
to a completely new world.
58
187840
3240
03:23
We'd known since the 1680s about bacteria.
59
191720
2976
03:26
We just didn't know
that bacteria killed people.
60
194720
2456
03:29
And he also demolished fond ideas
that people kept close to their heart.
61
197200
5056
03:34
Miasmas didn't kill people.
Bacteria killed people.
62
202280
3320
03:38
So this brings me to the two ideas
I want to talk about tonight.
63
206080
3336
03:41
One has opened our eyes
to a completely new universe,
64
209440
2816
03:44
and the other attacks long-held beliefs.
65
212280
3976
03:48
Let's get started with Dr. Eric Betzig.
66
216280
1936
03:50
He's a physicist who has opened our eyes
to an entirely new world
67
218240
3896
03:54
by violating the laws of physics.
68
222160
1880
03:56
Betzig is a true rebel.
69
224720
1280
03:58
He quit a job at prestigious
Bell Laboratory
70
226560
2896
04:01
inventing new microscopes for biology
71
229480
2256
04:03
because he thought scientists
were taking his brilliant inventions
72
231760
4336
04:08
and doing lousy work with them.
73
236120
1520
04:10
So he became a househusband,
74
238880
3040
04:15
but he never lost his passion
for figuring out
75
243360
2576
04:17
how to get microscopes
to see finer and finer details
76
245960
2896
04:20
than had ever been seen before
or ever could be seen.
77
248880
2477
04:23
This is crucial if we're ever
going to understand how cells work,
78
251960
4456
04:28
and how cancer works,
79
256440
1495
04:29
and how something
150th the size of a head of a pin
80
257959
5417
04:35
can do all these amazing things,
81
263400
2136
04:37
like make proteins
82
265560
1576
04:39
and move charges around
83
267160
1896
04:41
and all of those things.
84
269080
1280
04:43
There's just one problem.
85
271400
1680
04:46
There's this thing
called the law of physics,
86
274040
2976
04:49
and part of the law of physics
is the thing called the diffraction limit.
87
277040
3456
04:52
The diffraction limit is kind of like
when you go to a doctor's office,
88
280520
3376
04:55
you can only see so far down,
no matter how good glasses you have.
89
283920
3136
04:59
This was a so-called impossible problem.
90
287080
3376
05:02
But one of Betzig's friends
figured out how to take a tiny molecule
91
290480
3176
05:05
that was smaller than
the best microscope could see
92
293680
2416
05:08
and get it to light up and fluoresce.
93
296120
2136
05:10
"Aha!" Betzig said.
94
298280
2496
05:12
"I think maybe the laws of physics
are not so unbreakable after all."
95
300800
4696
05:17
So he lashed together a microscope
in his friend's living room.
96
305520
4856
05:22
He had no laboratory.
97
310400
1816
05:24
This revolutionary instrument
got different protein molecules
98
312240
3576
05:27
to light up in different colors,
99
315840
1560
05:30
and with a computer, he was able
to turn very, very fuzzy blurs
100
318080
4696
05:34
into very sharp dots and produce images
of unprecedented and startling clarity.
101
322800
6696
05:41
For this work, last year,
102
329520
2296
05:43
Eric Betzig won the Nobel Prize.
103
331840
2600
05:47
Why?
104
335360
1216
05:48
Because now we can see
with unprecedented detail
105
336600
4096
05:52
things that we never had seen before,
106
340720
1816
05:54
and now doctors can get
a better handle on things like cancer.
107
342560
3840
05:59
But do you think
Betzig was satisfied there?
108
347080
2496
06:01
No.
109
349600
1296
06:02
He wanted movies.
110
350920
1856
06:04
The problem was
111
352800
1216
06:06
that even the genius microscopes
that he invented were just too slow.
112
354040
3976
06:10
So what did he do?
113
358040
1256
06:11
He came up with a 200-year-old idea
114
359320
3576
06:14
called moiré patterns.
115
362920
1696
06:16
So the way that works is
if you take two very, very fine patterns
116
364640
3456
06:20
and you move them across each other,
117
368120
1776
06:21
you will see a gross pattern
118
369920
3016
06:24
that a microscope can see
119
372960
1480
06:27
that otherwise you would not
be able to see.
120
375360
2096
06:29
So he applied this technique
to taking a really blurry image of a cell
121
377480
3296
06:32
and moving lots of structured
light patterns across it
122
380800
2576
06:35
until this cell became crystal clear.
123
383400
2440
06:38
And here is the result:
124
386840
2016
06:40
a mysterious new world,
125
388880
2736
06:43
full of strange things zipping around
126
391640
2136
06:45
doing things that
we don't know what they're doing.
127
393800
2400
06:49
But when we figure it out,
we'll have a better handle on life itself.
128
397600
3976
06:53
For example, those
green globs that you see?
129
401600
2096
06:55
Those things are called clathrins.
130
403720
1680
06:57
They're molecules
that protect other molecules
131
405960
2416
07:00
as they move through a cell.
132
408400
1376
07:01
Unfortunately, viruses sometimes
hijack those to infect cells.
133
409800
4336
07:06
Also, you see those little squiggly
wormlike things moving around?
134
414160
3096
07:09
Those are actin molecules.
135
417280
2296
07:11
Unfortunately, viruses
also climb down those things
136
419600
2416
07:14
to get into the cell nucleus
137
422040
1456
07:15
to replicate themselves and make you sick.
138
423520
2120
07:18
Now that we can look at movies
139
426240
1856
07:20
of what's actually going on
deep inside a cell,
140
428120
2856
07:23
we have a much better chance
of curing viral diseases like AIDS.
141
431000
4080
07:27
So when you look at a movie like this,
142
435680
1856
07:29
it's very clear that Betzig has opened
our eyes to a completely new world.
143
437560
4000
07:34
But he hasn't shattered
any cherished beliefs.
144
442560
4120
07:39
That leads us to Dr. Aubrey de Grey
145
447200
2936
07:42
at Cambridge.
146
450160
1200
07:44
De Grey definitely has scientists
squirming with an interesting idea:
147
452440
4336
07:48
we can be immortal.
148
456800
1376
07:50
We can beat aging.
149
458200
1616
07:51
Now, most scientists
think he's a crackpot.
150
459840
2560
07:55
Any Biology 101 student knows
151
463320
3296
07:58
that aging is an inevitable
consequence of living.
152
466640
4016
08:02
For example, when we eat,
153
470680
2096
08:04
we take in food and we metabolize it,
154
472800
1856
08:06
and that throws off
what we call free radicals.
155
474680
2376
08:09
You might have heard of those.
156
477080
1456
08:10
Also known as oxygen ions,
157
478560
1936
08:12
those bind to our DNA, cause it to mutate,
158
480520
2376
08:14
and cause us to get old and lose our hair.
159
482920
2056
08:17
(Laughter)
160
485000
1576
08:18
It's just like, no, it's exactly like
161
486600
2736
08:21
oxygen binding to iron and making it rust.
162
489360
2176
08:23
So you age because you rust out.
163
491560
2456
08:26
(Laughter)
164
494040
2176
08:28
Oh, and scientists also know
there is something called immortality:
165
496240
5096
08:33
in cancer cells.
166
501360
1976
08:35
So if you stop aging,
167
503360
2296
08:37
all of you are going to turn
into giant walking malignant tumors.
168
505680
3920
08:42
These are cherished beliefs,
but could de Grey be on to something?
169
510680
3160
08:47
I think he deserves a closer look.
170
515159
1657
08:48
First of all, I have a really hard time
seeing him as a crackpot.
171
516840
3136
08:52
Yeah, he started off life
as a computer scientist,
172
520000
2336
08:54
not a biologist,
173
522360
1496
08:55
but he earned a PhD
in biology from Cambridge,
174
523880
3816
08:59
and he has published
some very significant work
175
527720
2376
09:02
on mitochondrial DNA
and a bunch of other stuff.
176
530120
2456
09:04
Secondly, he started
an antiaging foundation
177
532600
3096
09:07
that has identified
seven different causes of aging,
178
535720
2576
09:10
to me, that seem very plausible,
179
538320
2256
09:12
and he is hot in pursuit
of fixes for every single one of them.
180
540600
4136
09:16
For example, one of the reasons we age
is that our mitochondrial DNA mutates,
181
544760
5016
09:21
and we get kind of old
and our cells lose energy.
182
549800
2680
09:25
He believes, and he's made
a convincing case,
183
553160
2336
09:27
that using viruses we can do gene therapy,
184
555520
2536
09:30
fix that DNA
185
558080
1656
09:31
and rejuvenate our cells.
186
559760
1720
09:35
One more thing.
187
563400
1336
09:36
We have an existent proof
188
564760
1856
09:38
that extreme longevity is possible.
189
566640
2720
09:42
Bristlecone pine trees live 5,000 years,
190
570520
4160
09:47
and some lobsters don't age at all.
191
575720
3800
09:52
Now, this doesn't mean that de Grey
is going to revolutionize our lifespans.
192
580640
4336
09:57
I mean, after all, we're not trees,
and most of us are not lobsters.
193
585000
3816
10:00
(Laughter)
194
588840
1216
10:02
But I've got to believe that there are
Darwins and Einsteins out there,
195
590080
4800
10:07
and I'll tell you why.
196
595840
1376
10:09
Consider this:
197
597240
1200
10:11
there are seven times more people
alive today than during Darwin's time.
198
599160
5296
10:16
There are four times as many people
alive today as Einstein.
199
604480
3456
10:19
When you consider
200
607960
1216
10:21
that the proportion of scientists
in the population has skyrocketed,
201
609200
3216
10:24
there are now seven million scientists.
202
612440
2376
10:26
I've got to believe, and I do believe,
that there's one of them out there
203
614840
3440
10:31
who is working right now in obscurity
204
619720
2336
10:34
to rock our lives,
and I don't know about you,
205
622080
2416
10:36
but I can't wait to be rocked.
206
624520
1816
10:38
Thank you.
