00:00:00,303 --> 00:00:04,941
今天我想要和大家谈谈
关于爱情的数学。

2
00:00:04,941 --> 00:00:06,681
我想大家都同意

3
00:00:06,681 --> 00:00:11,597
数学家在寻找真爱上特别在行。

4
00:00:11,597 --> 00:00:15,045
但那并不只是因为我们
沛然莫之能御的魅力、

5
00:00:15,045 --> 00:00:19,544
超凡的对话技巧，
和绝佳的笔盒，

6
00:00:19,544 --> 00:00:24,070
那也是因为我们真的
花了许多时间在数学上，

7
00:00:24,070 --> 00:00:26,462
计算如何找到完美的伴侣。

8
00:00:26,462 --> 00:00:29,875
现在，在此学科中我最爱的论文，名为

9
00:00:29,875 --> 00:00:33,371
“为什么我没有女友”
（笑声）

10
00:00:33,371 --> 00:00:37,091
Peter Backus 试着评比他寻得真爱的机会。

11
00:00:37,091 --> 00:00:39,457
现在，Peter 不是一个非常贪心的人。

12
00:00:39,457 --> 00:00:41,542
在英国所有适宜的女性对象中，

13
00:00:41,542 --> 00:00:44,955
Peter 所看的，就只是那个住在他附近的对象，

14
00:00:44,955 --> 00:00:46,856
某个处于适宜的年龄阶段，

15
00:00:46,856 --> 00:00:49,666
某个拥有大学文凭，

16
00:00:49,666 --> 00:00:51,824
某个他很有可能相处地不错的对象，

17
00:00:51,824 --> 00:00:53,900
某个有魅力的女子，

18
00:00:53,900 --> 00:00:56,438
以及某个认为他也富有魅力的对象。

19
00:00:56,438 --> 00:00:59,441
（笑声）

20
00:00:59,441 --> 00:01:04,427
结果他估计在全英国大概有 26 位此类女性。

21
00:01:05,441 --> 00:01:07,602
这看来很不妙，不是吗，Peter？

22
00:01:07,602 --> 00:01:09,469
我们好好思考一下这件事，

23
00:01:09,469 --> 00:01:12,574
在无数聪明外星生命形式存在的情况下，

24
00:01:12,574 --> 00:01:16,799
那是少于 400 倍数的估计呀。

25
00:01:16,799 --> 00:01:21,676
那也给了 Pete 一个

26
00:01:21,676 --> 00:01:23,902
在某晚遇见一个特别的女子

27
00:01:23,902 --> 00:01:25,288
28 万 5 千之 1 的机会。

28
00:01:25,288 --> 00:01:27,491
我宁愿想着那就是为什么数学家

29
00:01:27,491 --> 00:01:30,915
不再怎么想晚上出去约会了。

30
00:01:30,915 --> 00:01:32,644
重点是，我个人其实并不同意

31
00:01:32,644 --> 00:01:35,373
这种悲观的看法。

32
00:01:35,373 --> 00:01:37,602
因为我知道，如同你们所有所知道的，

33
00:01:37,602 --> 00:01:40,194
爱情并不是这样发生的。

34
00:01:40,194 --> 00:01:45,304
人类的情感不是那样地秩序井然、
干净利落、逻辑清晰，以及容易预测。

35
00:01:45,304 --> 00:01:47,711
但我也知道那并不意谓着

36
00:01:47,711 --> 00:01:51,015
数学无法提供帮助，

37
00:01:51,015 --> 00:01:54,966
因为爱情，如同生命中多数的事物一般，
充斥着许多规律，

38
00:01:54,966 --> 00:01:59,042
而数学，最终，就是那关于规律之学。

39
00:01:59,042 --> 00:02:03,345
从预测天候，到预测股票市场的开高走低，

40
00:02:03,345 --> 00:02:06,750
到星球的运转，或都市的发展。

41
00:02:06,750 --> 00:02:09,454


42
00:02:09,454 --> 00:02:12,850


43
00:02:12,850 --> 00:02:17,877


44
00:02:17,877 --> 00:02:21,631


45
00:02:21,631 --> 00:02:25,187


46
00:02:25,187 --> 00:02:26,675


47
00:02:26,675 --> 00:02:31,236


48
00:02:31,236 --> 00:02:39,220


49
00:02:39,980 --> 00:02:41,939


50
00:02:41,939 --> 00:02:44,903


51
00:02:46,323 --> 00:02:50,159


52
00:02:50,159 --> 00:02:53,574


53
00:02:53,574 --> 00:02:55,343


54
00:02:55,343 --> 00:02:57,083


55
00:02:57,083 --> 00:02:59,936


56
00:02:59,936 --> 00:03:02,200


57
00:03:02,200 --> 00:03:04,067


58
00:03:04,067 --> 00:03:06,184


59
00:03:06,184 --> 00:03:07,876


60
00:03:07,876 --> 00:03:10,825


61
00:03:10,825 --> 00:03:12,447


62
00:03:12,447 --> 00:03:15,827


63
00:03:15,827 --> 00:03:21,672


64
00:03:21,679 --> 00:03:25,391


65
00:03:25,391 --> 00:03:28,260


66
00:03:28,260 --> 00:03:30,066


67
00:03:30,066 --> 00:03:34,565

00:03:43,362 --> 00:03:46,216


72
00:03:46,216 --> 00:03:47,876

00:03:47,876 --> 00:03:51,854

00:03:51,854 --> 00:03:55,177

00:03:55,177 --> 00:03:58,230

00:03:58,230 --> 00:04:01,058
