每個城市都有自己的街坊、圈圈及社團，無形的線聚集或區隔了同一城鎮的人。從眾人在網上的分享能看出城市什麼端倪？大維·特洛伊從自己的城市巴爾的摩開始，將城市居民的推文視覺化，顯示他們住在那區，跟誰說話，及不跟誰說話。

When we think about mapping cities,
0

1775
每當我們想到繪製城市地圖，
00:14
we tend to think about roads
and streets and buildings,
and streets and buildings,
1
2395
2805
我們很容易想到街道及建築物，
00:17
and the settlement narrative
that led to their creation,
that led to their creation,
2
5200
2800
以及村落追溯起源的故事，
00:20
or you might think about
the bold vision of an urban designer,
the bold vision of an urban designer,

8000
2984
你可能還會想到
都市設計師的大膽願景，
都市設計師的大膽願景，
00:22
but there's other ways
to think about mapping cities
to think about mapping cities
4
10984
2503
但是還有其他的方法繪製城市，
00:25
and how they got to be made.
5
13487
2166
及如何表現出來。
00:27
Today, I want to show you
a new kind of map.
a new kind of map.
6
15653
2093
今天，我要讓你們看一下新種地圖。
00:29
This is not a geographic map.
7
17746
1496
這不是地理圖。
00:31
This is a map of the relationships
between people in my hometown
between people in my hometown
8
19242
3131
這是我住的城市的人際關係圖，
00:34
of Baltimore, Maryland,
9
22373
1340
即馬里蘭州巴爾的摩市。
00:35
and what you can see here is that
each dot represents a person,
each dot represents a person,
10
23713
4417
你們在這裡看見的
每個點都代表一個人，
每個點都代表一個人，
00:40
each line represents a relationship
between those people,
between those people,
11
28130
3294
每條線代表人與人之間的關係，
00:43
and each color represents a community
within the network.
within the network.
12
31424
3446
每個顏色則代表
網絡上的不同社群。
網絡上的不同社群。
00:46
Now, I'm here on the green side,
down on the far right where the geeks are,
down on the far right where the geeks are,
13
34870
4862
那，我在綠色這邊，
即下面最右邊技客所在地，
即下面最右邊技客所在地，
00:51
and TEDx also is down
on the far right. (Laughter)
on the far right. (Laughter)
14
39732
3848
TEDx 也在下面最右邊。（笑聲）
00:55
Now, on the other side of the network,
15
43580
2577
那，網絡的另一邊，
00:58
you tend to have primarily
African-American and Latino folks
African-American and Latino folks
16
46157
2960
有非洲裔及拉丁裔群集的傾向，
01:01
who are really concerned about somewhat
different things than the geeks are,
different things than the geeks are,
17
49117
3590
他們真正關心的跟技客大不同，
01:04
but just to give some sense,
18
52707
1441
但要讓你們更瞭解情況，
01:06
the green part of the network
we call Smalltimore,
we call Smalltimore,
19
54148
2406
網絡上綠色的部份
我們稱之為小巴爾的摩，
我們稱之為小巴爾的摩，
01:08
for those of us that inhabit it,
20
56554
1545
我們這些當地居民都這麼叫它，
01:10
because it seems as though
we're living in a very small town.
we're living in a very small town.
21
58099
2915
因為我們就好像
住在一個小城一樣。
住在一個小城一樣。
01:13
We see the same people
over and over again,
over and over again,
22
61014
2034
我們總是看到同一批人，
01:15
but that's because
we're not really exploring
we're not really exploring
23
63048
2171
但那是因為我們沒有真正去探索
01:17
the full depth and breadth of the city.
24
65219
2862
這個城市的深度與廣度。
01:20
On the other end of the network,
25
68081
1752
在網絡的另一端，
01:21
you have folks who are interested
in things like hip-hop music
in things like hip-hop music
26
69833
2937
你有對嘻哈音樂感興趣的人，
01:24
and they even identify with living
in the DC/Maryland/Virginia area
in the DC/Maryland/Virginia area
27
72770
3804
他們甚至認為自己還比較像
生活在大華府地區的人，
生活在大華府地區的人，
01:28
over, say, the Baltimore city
designation proper.
designation proper.
28
76574
4416
不像巴爾的摩人。
01:32
But in the middle, you see that there's
29
80990
2100
但在中間，你們可以看見
01:35
something that connects
the two communities together,
the two communities together,
30
83090
2483
有東西將這兩個族群連在一起，
01:37
and that's sports.
31
85573
879
那就是運動。
01:38
We have the Baltimore Orioles,
the Baltimore Ravens football team,
the Baltimore Ravens football team,
32
86452
3088
我們有巴爾的摩金鶯隊，
巴爾的摩烏鴉美式足球隊，
巴爾的摩烏鴉美式足球隊，
01:41
Michael Phelps, the Olympian.
33
89540
1446
麥可·菲爾普斯，奧運選手。
01:42
Under Armour, you may have heard of,
is a Baltimore company,
is a Baltimore company,
34
90986
2838
安德瑪 (Under Armour) 運動品牌，
你們大概聽過，是家巴爾的摩公司，
你們大概聽過，是家巴爾的摩公司，
01:45
and that community of sports
acts as the only bridge
acts as the only bridge
35
93824
2433
而那個運動族群
01:48
between these two ends of the network.
36
96257
2271
是這網絡兩端的唯一橋樑。
01:50
Let's take a look at San Francisco.
37
98528
1895
再來看看舊金山。
01:52
You see something a little bit
different happening in San Francisco.
different happening in San Francisco.
38
100423
3186
你看舊金山的情況有點不同。
01:55
On the one hand, you do have
the media, politics and news lobe
the media, politics and news lobe
39
103609
4393
一方面，你的確有
媒體、政治及新聞那塊
媒體、政治及新聞那塊
02:00
that tends to exist
in Baltimore and other cities,
in Baltimore and other cities,
40
108002
2535
跟巴爾的摩及其他城市一樣，
02:02
but you also have this
very predominant group
very predominant group
41
110537
2355
但你也有這塊非常明顯的
02:04
of geeks and techies that are sort of
taking over the top half of the network,
taking over the top half of the network,
42
112892
4393
技客和電子族群，
他們占了網絡的上半部，
他們占了網絡的上半部，
02:09
and there's even a group
that's so distinct and clear
that's so distinct and clear
43
117285
2502
還有一群人，非常清楚明顯，
02:11
that we can identify it
as Twitter employees,
as Twitter employees,
44
119787
2350
我們都能看出他們是推特員工，
02:14
next to the geeks, in between
the gamers and the geeks,
the gamers and the geeks,
45
122137
3367
位在技客旁邊，
在電玩家與技客之間，
在電玩家與技客之間，
02:17
at the opposite end
of the hip-hop spectrum.
of the hip-hop spectrum.
46
125504
2941
在嘻哈端的另一頭。
02:20
So you can see, though,
47
128445
1717
然而你們可以看到，
02:22
that the tensions that we've
heard about in San Francisco
heard about in San Francisco
48
130162
2681
我們聽說在舊金山有種緊張情勢，
02:24
in terms of people being
concerned about gentrification
concerned about gentrification
49
132843
2921
就是人們擔心仕紳化，
02:27
and all the new tech companies
that are bringing new wealth
that are bringing new wealth
50
135764
2759
及科技新貴公司把新財富
02:30
and settlement into the city are real,
51
138523
2097
及新社區帶進城市的
情況其實很真實，
情況其實很真實，
02:32
and you can actually see
that documented here.
that documented here.
52
140620
2229
你們可以從這個看出來。
02:34
You can see the LGBT community
53
142849
2020
你們可以看到同性戀族群
02:36
is not really getting along
with the geek community that well,
with the geek community that well,
54
144869
3296
與技客族群相處並不那麼融洽，
02:40
the arts community, the music community.
55
148165
2132
還有藝術族群，音樂族群。
02:42
And so it leads to things like this.
56
150297
1773
所以就產生了這個。
02:44
["Evict Twitter"]
57
152070
973
「驅逐推特」
02:45
Somebody sent me this photo
a few weeks ago,
a few weeks ago,
58
153043
1824
有人幾星期前傳了這張照片給我，
02:46
and it shows what is happening
on the ground in San Francisco,
on the ground in San Francisco,
59
154867
2907
這顯示了在舊金山那裡的情況，
02:49
and I think you can
actually try to understand that
actually try to understand that
60
157774
2384
我想你真的可以透過
研究像這樣的地圖
研究像這樣的地圖
02:52
through looking at a map like this.
61
160158
1702
去試著瞭解狀況。
02:53
Let's take a look at Rio de Janeiro.
62
161860
1760
再來看里約熱內盧。
02:55
I spent the last few weeks
gathering data about Rio,
gathering data about Rio,
63
163620
2454
我花了過去幾個星期
收集里約的資料，
收集里約的資料，
02:58
and one of the things
that stood out to me about this city
that stood out to me about this city
64
166074
2807
有一件事特別吸引我注意，
03:00
is that everything's
really kind of mixed up.
really kind of mixed up.
65
168881
2122
就是這真的是個大混缸。
03:03
It's a very heterogenous city in a way
that Baltimore or San Francisco is not.
that Baltimore or San Francisco is not.
66
171003
4104
這是個非常混雜的城市，
與巴爾的摩和舊金山非常不同。
與巴爾的摩和舊金山非常不同。
03:07
You still have the lobe of people involved
67
175107
2455
你仍然有人從事與
03:09
with government, newspapers,
politics, columnists.
politics, columnists.
68
177562
2384
政府、報紙、政治、
專欄等有關的活動。
專欄等有關的活動。
03:11
TEDxRio is down in the lower right,
right next to bloggers and writers.
right next to bloggers and writers.
69
179946
3404
TEDxRio 就在右下，
與部落格主及作家相鄰。
與部落格主及作家相鄰。
03:15
But then you also have this
tremendous diversity of people
tremendous diversity of people
70
183350
2709
但也有一群極大多樣性的人
03:18
that are interested
in different kinds of music.
in different kinds of music.
71
186059
2274
對各式不同的音樂有興趣。
03:20
Even Justin Bieber fans
are represented here.
are represented here.
72
188333
2204
甚至小賈斯汀也有粉絲在這。
03:22
Other boy bands, country singers,
73
190537
2892
其他的男孩團體、鄉村歌手、
03:25
gospel music, funk and rap
and stand-up comedy,
and stand-up comedy,
74
193429
2908
福音音樂、放克饒舌及單人脫口秀，
03:28
and there's even a whole section
around drugs and jokes.
around drugs and jokes.
75
196337
3039
甚至有一整塊是毒品及笑話。
03:31
How cool is that?
76
199376
1486
這多酷啊！
03:32
And then the Flamengo football team
is also represented here.
is also represented here.
77
200862
3134
然後佛朗明哥足球隊也有一塊。
03:35
So you have that same kind of spread
78
203996
2160
所以同樣是有
03:38
of sports and civics
and the arts and music,
and the arts and music,
79
206156
2715
體育、市政、藝術、音樂的分佈，
03:40
but it's represented
in a very different way,
in a very different way,
80
208871
2161
但分佈的方式卻截然不同，
03:43
and I think that maybe fits
with our understanding of Rio
with our understanding of Rio
81
211032
3320
我認為那大概與我們
所瞭解的里約相符，
所瞭解的里約相符，
03:46
as being a very multicultural,
musically diverse city.
musically diverse city.
82
214352
4014
就是一個非常多文化、
音樂多元的城市。
音樂多元的城市。
03:50
So we have all this data.
83
218366
3618
所以我們有這些資料。
03:53
It's an incredibly rich set of data
that we have about cities now,
that we have about cities now,
84
221984
3118
這組與城市有關的資料非常豐富，
03:57
maybe even richer than any data set
that we've ever had before.
that we've ever had before.
85
225102
3246
可能甚至比我們之前
所有的資料都要豐富。
所有的資料都要豐富。
04:00
So what can we do with it?
86
228348
1924
所以我們要怎麼用它呢？
04:02
Well, I think the first thing
that we can try to understand
that we can try to understand
87
230272
2870
嗯，我想我們首先要試著去瞭解的是
04:05
is that segregation is a social construct.
88
233142
2338
隔離其實是一種社會建構。
04:07
It's something that we choose to do,
and we could choose not to do it,
and we could choose not to do it,
89
235480
3344
這是我們選擇要做的，
我們也能選擇不要做，
我們也能選擇不要做，
04:10
and if you kind of think about it,
90
238824
1932
如果你想一下，
04:12
what we're doing with this data
is aiming a space telescope at a city
is aiming a space telescope at a city
91
240756
3411
我們拿這組資料所做的，
就像拿太空望遠鏡來看城市，
就像拿太空望遠鏡來看城市，
04:16
and looking at it as if was
a giant high school cafeteria,
a giant high school cafeteria,
92
244167
3032
就好像在一座龐大的高中自助餐廳，
04:19
and seeing how everybody arranged
themselves in a seating chart.
themselves in a seating chart.
93
247199
3738
去看每一個人怎麼
安排自己的座位一樣。
安排自己的座位一樣。
04:22
Well maybe it's time to shake up
the seating chart a little bit.
the seating chart a little bit.
94
250937
3313
可能是該重新改變座位表的時候了！
04:26
The other thing that we start to realize
95
254250
2540
我們開始瞭解的另一件事是，
04:28
is that race is a really
poor proxy for diversity.
poor proxy for diversity.
96
256790
2638
用種族來代表多樣性
是很糟的方法。
是很糟的方法。
04:31
We've got people represented
from all different types of races
from all different types of races
97
259428
2937
我們有各式各樣的人種
04:34
across the entire map here --
98
262365
2326
分布在這整張地圖上，
04:36
only looking at race
99
264691
2376
只看種族
04:39
doesn't really contribute to
our development of diversity.
our development of diversity.
100
267067
2718
不能看出多樣性的真實發展。
04:41
So if we're trying to use diversity
101
269785
1739
所以如果我們試著用多樣性
04:43
as a way to tackle some of our
more intractable problems,
more intractable problems,
102
271524
3081
來解決一些棘手的問題，
04:46
we need to start to think
about diversity in a new way.
about diversity in a new way.
103
274605
3294
我們必須開始用
新的方法思考多樣性。
新的方法思考多樣性。
04:49
And lastly, we have the ability to create
104
277899
3527
最後，我們有能力去干預，
04:53
interventions to start to reshape
our cities in a new way,
our cities in a new way,
105
281426
3094
以新方法開始重塑我們的城市，
04:56
and I believe that if
we have that capability,
we have that capability,
106
284520
2600
而且我相信如果我們有那種能力，
04:59
we may even bear some
responsibility to do so.
responsibility to do so.
107
287120
3065
我們甚至還能扛起責任來做這件事。
05:02
So what is a city?
108
290185
1765
所以，什麼是城市？
05:03
I think some might say that it is
109
291950
2206
我想有些人或許會說它是
05:06
a geographical area or a collection
of streets and buildings,
of streets and buildings,
110
294156
3160
地理區域或街道及建築物的組合，
05:09
but I believe that a city
is the sum of the relationships
is the sum of the relationships
111
297316
2752
但我相信一座城市
是所有居民的關係總和。
05:12
of the people that live there,
112
300068
1561
05:13
and I believe that if we can start to
document those relationships in a real way
document those relationships in a real way
113
301629
6051
而且我相信如果我們能以
真實的方法記錄這些關係，
真實的方法記錄這些關係，
05:19
then maybe we have a real shot
114
307680
1733
那或許我們真的有機會
05:21
at creating those kinds of cities
that we'd like to have.
that we'd like to have.
115
309413
2675
創造我們想要的城市。
05:24
Thank you.
116
312088
1357
謝謝。
05:25
