I was offered a position as associate professor of medicine

3000
我曾經在耶魯大學
00:18
and chief of scientific visualization
1
3000
3000
擔任醫學系
00:21
at Yale University
2
6000
2000
副教授
00:23
in the department of medicine.
3
8000
2000
以及科學視覺化主任。
00:25
And my job was to write many of the algorithms and code
4
10000
3000
我的工作是替美國太空總署寫演算法及程式
00:28
for NASA to do virtual surgery
5
13000
2000
讓即將出發進入太空飛行的宇航員
00:30
in preparation for the astronauts going into deep spaceflight,
6
15000
3000
練習做虛擬手術,
00:33
so they could be kept in robotic pods.
7
18000
2000
因而太空人可以在太空裝內做實驗。
00:35
One of the fascinating things about what we were actually working on
8
20000
2000
我們的計畫裡有一件很有趣的事,
00:37
is that we were seeing, using new kinds of scanning technologies,
9
22000
3000
就是我們透過最新的掃描科技
00:40
things that had just never been seen before --
10
25000
2000
觀看那些前所未見的東西--
00:42
I mean, not only in disease management,
11
27000
2000
我的意思是，新科技不僅運用於疾病管理,
00:44
but also things that allowed us to see things about the body
12
29000
4000
還可以讓我們看到那些
00:48
that just made you marvel.
13
33000
3000
讓你驚嘆不已的身體結構。
00:51
I remember one of the first times we were looking at collagen.
14
36000
3000
我記得我們最初幾次看膠原蛋白。
00:54
And your entire body, everything --
15
39000
2000
你全身所有的構造--
00:56
your hair, skin, bone, nails --
16
41000
2000
你的頭髮、皮膚、骨頭、指甲--
00:58
everything is made of collagen.
17
43000
2000
每一樣都由膠原蛋白組成。
01:00
And it's a kind of rope-like structure
18
45000
2000
它的結構很像繩子,
01:02
that twirls and swirls like this.
19
47000
2000
像這樣螺旋纏繞。
01:04
And the only place that collagen changes its structure
20
49000
4000
唯一一個膠原蛋白改變結構的地方
01:08
is in the cornea of your eye.
21
53000
2000
是你的角膜。
01:10
In your eye,
22
55000
2000
在你的眼睛裡,
01:12
it becomes a grid formation,
23
57000
2000
它變成格狀的結晶結構,
01:14
and therefore, it becomes transparent, as opposed to opaque.
24
59000
3000
因此它從原本的不透明變成透明的。
01:17
So perfectly organized a structure,
25
62000
3000
這個組織是如此的完美,
01:20
it was hard not to attribute divinity to it.
26
65000
2000
你很難不把它歸功於神蹟。
01:22
Because we kept on seeing this over and over and over again
27
67000
3000
因為我們不斷地在身體的不同部位
01:25
in different parts of the body.
28
70000
2000
看到這樣的結構。
01:27
One of the opportunities I had
29
72000
3000
我曾有個機會
01:30
was one person was working on a really interesting
30
75000
2000
是與一位在美國國立衛生研究院
01:32
micromagnetic resonance imaging machine with the NIH.
31
77000
3000
研究非常有趣的核磁共振的人共事。
01:35
And what we were going to do
32
80000
2000
我們做的事情
01:37
was scan a new project
33
82000
2000
是發展一個新計畫,
01:39
on the development of the fetus from conception to birth
34
84000
2000
要使用這些新科技
01:41
using these kinds of new technologies.
35
86000
2000
掃描從受孕到出生的胎兒發育。
01:43
So I wrote the algorithms in code,
36
88000
2000
所以我寫了一些演算程式,
01:45
and he built the hardware -- Paul Lauterbur --
37
90000
3000
而他--美國化學教授羅特博--則製造機器,
01:48
then went onto win the Nobel Prize for inventing the MRI.
38
93000
3000
他後來因為發明核磁共振而得到諾貝爾獎。
01:51
I got the data.
39
96000
2000
而我得到了這些資料。
01:53
And I'm going to show you a sample of the piece,
40
98000
2000
我現在要播出這個計畫的部分成果
01:55
"From Conception to Birth."

36天：脊椎骨的原始形態出現
03:11
These weeks are the period of the most rapid development of the fetus.
55
176000
7000
這幾個星期是胚胎成長最快速的時期。
03:24
If the fetus continues to grow at this speed for the entire nine months,
56
189000
3000
如果胚胎在這九個月都照這個速率持續成長,
03:27
it would be 1.5 tons at birth.
57
192000
2000
寶寶出生時會重達1.5噸。

胎兒在子宮裡不停地動
04:08
is necessary for muscular and skeletal growth.
63
233000
5000
對肌肉及骨骼的生長不可或缺。
04:25
12 Weeks: Indifferent penis --

Alexander Tsiaras: Thank you.
70
341000
2000
亞歷山大：謝謝。
05:58
But as you can see,
71
343000
2000
不過正如你所見,
06:00
when you actually start working on this data,
72
345000
2000
當你開始處理這些資料,
06:02
it's pretty spectacular.
73
347000
2000
其實是很壯觀的。
06:04
And as we kept on scanning more and more,
74
349000
2000
而且當我們繼續的掃描,
06:06
working on this project,
75
351000
2000
持續進行這個計畫,
06:08
looking at these two simple cells
76
353000
2000
看著這兩個簡單的細胞
06:10
that have this kind of unbelievable machinery
77
355000
3000
居然擁有這種令人無法置信的機制
06:13
that will become the magic of you.
78
358000
2000
可以長成神奇的「你」。
06:15
And as we kept on working on this data,
79
360000
2000
當我們繼續處理資料
06:17
looking at small clusters of the body,
80
362000
3000
看著身體的這個小小的部分,
06:20
these little pieces of tissue
81
365000
3000
這團小小的組織
06:23
that were a trophoblast coming off of a blastocyst,
82
368000
2000
從囊胚分化出來的滋養細胞群,
06:25
all of a sudden burrowing itself into the side of the uterus,
83
370000
3000
瞬間就在子宮壁上著床,
06:28
saying, "I'm here to stay."
84
373000
2000
說：「我要在這停留。」
06:30
All of a sudden having conversation and communications
85
375000
2000
瞬間就跟雌激素及黃體素
06:32
with the estrogens, the progesterones,
86
377000
2000
對話及溝通,
06:34
saying, "I'm here to stay, plant me,"
87
379000
2000
說：「我要在這裡長大，養我。」
06:36
building this incredible trilinear fetus
88
381000
3000
長成這個不可思議的三胚層胚胎,
06:39
that becomes, within 44 days,
89
384000
2000
在44天內
06:41
something that you can recognize,
90
386000
2000
長成一個你可以辨識的胎兒雛形,
06:43
and then at nine weeks
91
388000
2000
然後在九週內
06:45
is really kind of a little human being.
92
390000
2000
長成一個小小的人。
06:47
The marvel of this information:
93
392000
2000
這項資訊令人驚異之處在於
06:49
How do we actually have this biological mechanism
94
394000
2000
到底我們是如何在體內
06:51
inside our body
95
396000
2000
擁有這樣的生物機制
06:53
to actually see this information?
96
398000
2000
能夠了解這樣的資訊？
06:55
I'm going to show you something pretty unique.
97
400000
2000
我們來看一段非常特別的東西。
06:57
Here's a human heart at 25 [weeks].
98
402000
2000
這個是胎兒在25週大時的心臟。
06:59
It's just basically two strands.
99
404000
2000
看起來只是兩股絞線。
07:01
And like this magnificent origami,
100
406000
2000
就像美麗的摺紙,
07:03
cells are developing
101
408000
2000
細胞成長的速率
07:05
at one million cells per second at four weeks,
102
410000
3000
在第四週時為每一秒產生一百萬個細胞,
07:08
as it's just folding on itself.
103
413000
2000
就好像自己在摺疊複製自己。
07:10
Within five weeks, you can start to see the early atrium and the early ventricles.
104
415000
3000
五週內你就可以開始看見心房及腦室的初始結構。
07:13
Six weeks, these folds are now beginning
105
418000
2000
六週時，這些摺疊就開始
07:15
with the papilla on the inside of the heart
106
420000
2000
與心臟內的乳頭肌一起
07:17
actually being able to pull down
107
422000
2000
能夠拉扯
07:19
each one of those valves in your heart
108
424000
2000
你心臟裡的每一個瓣膜
07:21
until you get a mature heart --
109
426000
3000
直到你的心臟成熟為止--
07:24
and then basically the development of the entire human body.
110
429000
2000
直到你的全身結構發展完成。
07:26
The magic of the mechanisms
111
431000
2000
這些在每一個遺傳結構內
07:28
inside each genetic structure
112
433000
3000
準確的告訴神經細胞要去哪裡的機制,
07:31
saying exactly where that nerve cell should go --
113
436000
3000
其不可思議之處在於--
07:34
the complexity of these mathematical models
114
439000
2000
這些數學模型的複雜程度,
07:36
of how these things are indeed done
115
441000
2000
這些事情是怎樣發生的
07:38
are beyond human comprehension.
116
443000
2000
遠遠超過人類所能理解。
07:40
Even though I am a mathematician,
117
445000
2000
即使像我身為數學家,
07:42
I look at this with marvel
118
447000
2000
我也要驚嘆
07:44
of how do these instruction sets
119
449000
3000
當我們在成形的時候
07:47
not make these mistakes
120
452000
2000
是如何讓這些指令
07:49
as they build what is us?
121
454000
2000
不出錯？
07:51
It's a mystery, it's magic, it's divinity.
122
456000
2000
這真神秘，真不可思議，真是神蹟。
07:53
Then you start to take a look at adult life.
123
458000
3000
然後你開始觀察成人的生命。
07:56
Take a look at this little tuft of capillaries.
124
461000
2000
看看這些小小綹的微血管。
07:58
It's just a tiny sub-substructure, microscopic.
125
463000
3000
這只是一個微小的次次結構，非常微觀的。
08:01
But basically by the time you're nine months and you're given birth,
126
466000
4000
但是基本上當你在體內九個月大，即將出生時,
08:05
you have almost 60,000 miles of vessels
127
470000
3000
你的體內擁有
08:08
inside your body.
128
473000
2000
將近六萬英哩（九萬六千多公里）的血管。
08:10
I mean, and only one mile is visible.
129
475000
2000
而且只有一英哩是看的見的。
08:12
59,999 miles
130
477000
3000
其他的59,999英哩
08:15
that are basically bringing nutrients and taking waste away.
131
480000
3000
基本上都在輸送營養及帶走廢物。
08:18
The complexity of building that within a single system
132
483000
2000
在一個單一系統內建造這個的複雜度,
08:20
is, again, beyond any comprehension
133
485000
2000
再說一次，是超乎理解的,
08:22
or any existing mathematics today.
134
487000
2000
也不是所有現存的數學公式可以解答的。
08:24
And that instruction set,
135
489000
2000
而這些指令,
08:26
from the brain to every other part of the body --
136
491000
2000
從頭腦到身體的每一部分--
08:28
look at the complexity of the folding.
137
493000
2000
看看這些摺疊有多複雜。
08:30
Where does this intelligence
138
495000
2000
到底身體從何而知
08:32
of knowing that a fold can actually hold more information,
139
497000
2000
摺疊結構其實可以儲存更多的資料,
08:34
so as you actually watch the baby's brain grow --
140
499000
3000
所以現在你在看的是寶寶的腦子成長--
08:37
and this is one of the things that we're doing right now.
141
502000
2000
這也正是我們在做的事。
08:39
We're actually doing the launch of two new studies
142
504000
2000
我們正開始作兩個新的研究
08:41
of actually scanning babies' brains from the moment they're born.
143
506000
3000
要從寶寶一出生起就開始掃瞄他們的腦子。
08:44
Every six months until they're six years old --
144
509000
2000
每六個月掃瞄一次，直到他們六歲為止--
08:46
we're going to be doing actually to about 250 children --
145
511000
3000
我們要掃描大約250個小孩--
08:49
watching exactly how the gyri and the sulci of the brains fold
146
514000
3000
觀察他們的腦迴及腦溝如何發展
08:52
to see how this magnificent development
147
517000
2000
觀察這個令人讚嘆的發展,
08:54
actually turns into memories and the marvel that is us.
148
519000
3000
如何轉化成記憶及奇蹟的「我們」。
08:57
And it's not just our own existence,
149
522000
2000
而且這奇蹟不僅僅在於我們的存在本身,
08:59
but how does the woman's body understand
150
524000
2000
還在於女性的身體要如何理解
09:01
to have genetic structure that not only builds her own,
151
526000
3000
這些遺傳結構，不但讓她自己成長,
09:04
but then has the understanding
152
529000
2000
而且還能了解到
09:06
that allows her to become
153
531000
2000
自己要成為
09:08
a walking immunological, cardiovascular system
154
533000
3000
一個活的免疫及心血管系統
09:11
that basically is a mobile system
155
536000
2000
基本上就是一個行動保溫箱,
09:13
that can actually nurture, treat this child with a kind of marvel
156
538000
4000
用這種奇妙的方法培育、對待孩子,
09:17
that is beyond, again, our comprehension --
157
542000
3000
再說一次，這實在不是我們能理解的--
09:20
the magic that is existence, that is us?
158
545000
3000
而我們，人類的存在不就是奇蹟？
09:23
