0:00:00.303,0:00:04.941
今天我想要和大家谈谈[br]关于爱情的数学。

0:00:04.941,0:00:06.681
我想大家都同意

0:00:06.681,0:00:11.597
数学家在寻找真爱上特别在行。

0:00:11.597,0:00:15.045
但那并不只是因为我们[br]沛然莫之能御的魅力、

0:00:15.045,0:00:19.544
超凡的对话技巧，[br]和绝佳的笔盒，

0:00:19.544,0:00:24.070
那也是因为我们真的[br]花了许多时间在数学上，

0:00:24.070,0:00:26.462
计算如何找到完美的伴侣。

0:00:26.462,0:00:29.875
现在，在此学科中我最爱的论文，名为

0:00:29.875,0:00:33.371
“为什么我没有女友”[br]（笑声）

0:00:33.371,0:00:37.091
Peter Backus 试着评比他寻得真爱的机会。

0:00:37.091,0:00:39.457
现在，Peter 不是一个非常贪心的人。

0:00:39.457,0:00:41.542
在英国所有适宜的女性对象中，

0:00:41.542,0:00:44.955
Peter 所看的，就只是那个住在他附近的对象，

0:00:44.955,0:00:46.856
某个处于适宜的年龄阶段，

0:00:46.856,0:00:49.666
某个拥有大学文凭，

0:00:49.666,0:00:51.824
某个他很有可能相处地不错的对象，

0:00:51.824,0:00:53.900
某个有魅力的女子，

0:00:53.900,0:00:56.438
以及某个认为他也富有魅力的对象。

0:00:56.438,0:00:59.441
（笑声）

0:00:59.441,0:01:04.427
结果他估计在全英国大概有 26 位此类女性。

0:01:05.441,0:01:07.602
这看来很不妙，不是吗，Peter？

0:01:07.602,0:01:09.469
我们好好思考一下这件事，

0:01:09.469,0:01:12.574
在无数聪明外星生命形式存在的情况下，

0:01:12.574,0:01:16.799
那是少于 400 倍数的估计呀。

0:01:16.799,0:01:21.676
那也给了 Pete 一个

0:01:21.676,0:01:23.902
在某晚遇见一个特别的女子

0:01:23.902,0:01:25.288
28 万 5 千之 1 的机会。

0:01:25.288,0:01:27.491
我宁愿想着那就是为什么数学家

0:01:27.491,0:01:30.915
不再怎么想晚上出去约会了。

0:01:30.915,0:01:32.644
重点是，我个人其实并不同意

0:01:32.644,0:01:35.373
这种悲观的看法。

0:01:35.373,0:01:37.602
因为我知道，如同你们所有所知道的，

0:01:37.602,0:01:40.194
爱情并不是这样发生的。

0:01:40.194,0:01:45.304
人类的情感不是那样地秩序井然、[br]干净利落、逻辑清晰，以及容易预测。

0:01:45.304,0:01:47.711
但我也知道那并不意谓着

0:01:47.711,0:01:51.015
数学无法提供帮助，

0:01:51.015,0:01:54.966
因为爱情，如同生命中多数的事物一般，[br]充斥着许多规律，

0:01:54.966,0:01:59.042
而数学，最终，就是那关于规律之学。

0:01:59.042,0:02:03.345
从预测天候，到预测股票市场的开高走低，

0:02:03.345,0:02:06.750
到星球的运转，或都市的发展。
