Today I want to tell to you about the mathematics of love.
今天我想和你们聊⼀下关于爱情的数学。
2
Now, I think that we can all agree that mathematicians are famously excellent at finding love.
女声合唱我认为我们都认同数学家在寻爱情⽅⾯出了名的优秀。
这篇⽂章我反复跟读了若⼲遍，某⼀次读到这句话的时候，突然想到这是不是在调侃诺贝尔？因为他的妻⼦就是跟⼀个数学家跑了。

But it's not just because of our dashing personalities, superior conversational skills and excellent pencil cases.
但这不仅仅是因为我们迷⼈的个性，出众的聊天技巧和好看的铅笔盒。
dashing adj. （尤指男⼦）风度翩翩的，浪漫迷⼈的；时髦的，流⾏的
eg：He's a dashing man, but he has been divorced 3 times.
这⾥的excellent pencil cases算是个⼩幽默
4
It's also because we've actually done an awful lot of work into the maths of how to find the perfect partner.
也因为我们实际上在数学上做了⼤量功课，关于如何到理想伴侣。
awful 表⽰程度很深，去掉不影响理解，类似修饰的⽤法在前⾯TED演讲中出现多次了
math是美式⽤法， mathmatics 的简称。
maths是英式⽤法，源于 mathmatics, 是复数名词，但是⽤法是按单数名词。
math和maths完全等效，就如同前⾯出现过的mom和mum。

Now, in my favorite paper on the subject, which is entitled, "Why I Don't Have a Girlfriend" -- Peter Backus tries to rate his chances of finding love.
关于这个话题，我最喜欢的⼀个论⽂标题为：为什么我没个⼥朋友 -- Peter Backus试图去估算到爱情的⼏率。
on the subject 就某话题
eg：They are arguing violently on the subject of whether or not to resign in this tough situation During the period of COVID -19.
6
Now, Peter's not a very greedy man.
Peter不是个贪婪的男⼈。
7
Of all of the available women in the UK, all Peter's looking for is
在英国所有合适的⼥性中，Peter要的是
即刻出发
洛洛整容8
Somebody who lives near him,
住得离他近，
9
somebody in the right age range,
在适龄区间，
10
somebody with a university degree,
有个⼤学本科⽂凭，
11
somebody he's likely to get on well with,
可能与之相处融洽的，
12
Somebody who's likely to be attractive,
有魅⼒的，
13
Somebody who's likely to find him attractive.
可能发现他有魅⼒的，
14
国会2012最新慢摇
And comes up with an estimate of 26 women in the whole of the UK.
然后得到了⼀个估算，在全英国，只有26个⼥性。
15
It's not looking very good, is it Peter?
看上去不怎么样，对吗？Peter。
16
Now, just to put that into perspective, that's about 400 times fewer than the best estimates of how many intelligent extraterrestrial life forms there are.
有⼀说⼀，这⽐存在多少外星智慧⽣命的最乐观估计要⼩400倍。
put something into perspective 全⾯公正地看待，在这⾥，演讲者有点调侃的意思。
eg：Put that into perspective, it was your fault, you should have told them what to do clearly.
这个B站视频是关于外星智能⽣命数量是如何计算的
Drake equation（德雷克公式）内容
从图中可以看出，根据这个公式，外星⽣命最乐观估计有100,000,000个，除以400就是250,000，与下⼀句中的数字285,000接近。
但是注意，这⾥拿的是外星⽣命数量和Peter到⼥朋友的概率相对⽐，⽽不是拿到外星⽣命的概率来对⽐。
17
And it also gives Peter a 1 in 285,000 chance of bumping into any one of these special ladies on a gi
ven night out.
这给了Peter285,000分之⼀的概率，在某⼀个外出的晚上碰到其中之⼀的天选之⼥。
bump into = encounter ⽆意中遇到、碰到
night out 节⽇的夜晚；外出的⼀夜
eg：Have you heard? Peter has got married just last week, it's said that he bumped into a very beautiful girl on a accidental night out.
18
I'd like to think that's why mathematicians don't really bother going on nights out any longer.
我想这就是为什么数学家不屑于晚上出去的原因吧。
bother doing 费事做；不屑做；⿇烦做某事
eg：I'd like to think that you just don't really bother thinking, and that's why you're so slowly when learning a new thing.
19
The thing is that I personally don't subscribe such a pessimistic view.
问题是，我个⼈不赞同这样⼀个悲观的观点。
the thing is是⼀个很常⽤的⼝语表达，类似于中⽂的“问题是”
subscribe vi. 订阅；捐款；认购；赞成；签署
一个人 蔡妍eg：The thing is that I personally don't subscribe to eat in that restaurant, because it's too expensive.
20
Because I know, just as well as all of you do, that love doesn't really work like that.
因为我知道，和你们知道的⼀样，爱情不是这样的。
21
Human emotion isn't neatly ordered and rational and easily predictable.
⼈类的情感不是井然有序、理性和易预测的。
22
But I also know that that doesn't mean that mathematics hasn't got something that it can offer us,
我还知道，这不意味着数学⽆法给我们带来⼀点帮助。
eg：I'm defeated again, but that doesn't mean it hasn't got something can offer me.
23
Because love, as with most of life, is full of patterns, and mathematics is ultimately all about the study of patterns.
因为爱情，和⼤多数⽣活⼀样，有迹可循，数学最终就是关于规律的研究。
24
Patterns from predicting the weather to the fluctuations in the stock market, to the movement of the planets or the growth
of cities.
这种规律从预测天⽓到股市波动，从地球运动到城市扩张。
25
And if we're being honest, none of those things are exactly neatly ordered and easily predictable, either.
⽼实说，那些事中没⼀个是井然有序和易预测的。
26
Because I believe that mathematics is so powerful that it has the potential to offer us a new way of looking at almost anything.
因为我认为，数学很强⼤，他能给我们观看⼏乎任何事情⼀个新的⽅法。
27
Even something as mysterious as love.
即使有些事情和爱情⼀样神秘。
28
And so, to try to persuade you of how totally amazing, excellent and relevant mathematics is, I want to give you my top 3 mathematically verifiable tips for love.
为了给你展⽰数学多么得神奇、优秀和与之相关，我想给你3个在数学上可被验证的重要建议。
verifiable adj. 可证实的；能作证的；可检验的
eg：If your opinion is not verifiable, I'd rather that you didn't say it.

Okay, so Top Tip #1: How to win at online dating.
重要建议1：如何玩转⽹上约会。
30
Ok, so my favorite online dating website is OkCupid, not least because it was started by a group of mathematicians.
我最喜欢的在线约会⽹站是OkCupid，尤其是因为它是由⼀数学家创办的。
31
Now, because they're mathematicians, they have been collecting data on everybody who uses their site for almost a decade.因为他们是数学家，他们⼀直在使⽤他们⽹站的⼈⾝上收集数据，差不多10年了。
我本来只想看看这个⽹站，结果进去注册了个号，玩了⼀晚上...
OkCupid
32
And they've been trying to search for patterns in the way that we talk about ourselves and the way that we interact with each other on an online dating website.
他们⼀直试图在寻我们谈论⾃⾝的⽅式，以及我们在在线约会⽹站上相互交流⽅式的规律。
33
And they've come up with some seriously interesting findings.
他们得到了⼀些⾮常有趣的发现。
34
But my particular favorite is that it turns out that on an online dating website, how attractive you are does not dictate how popular you are,
我最喜欢的⼀点是，结果表明，在在线约会⽹站中，你有魅⼒并不表明你很受欢迎，
35
And actually having people think that you're ugly can work to your advantage.
事实上，让⼈们认为你长得难看，会对你有优势。
36
Let me show you how this works.
我来给你们看下这是怎么回事。方力申的歌
37
Ok, so in a thankfully voluntary section of OkCupid, you are allowed to rate how attractive you think people are on a scale between 1 and 5.
在OkCupid上⼀个抽样调查环节，让你为⼈们的魅⼒打分，分值在1到5.
38
Now, if we compare this score, the average score, to how many messages a selection of people receive, you can begin to get a sense of how attractiveness links to popularity on an online dating website.
如果把这个平均分数，和这被选中的⼈所收到的信息做⽐较，你会开始感觉到，在⼀个在线约会⽹站中，魅⼒和受欢迎程度的关系。
a selection of ⼀组被挑选出的...
eg：There is a selection of chocolate that you picked just now.
39
Now so this is the graph that the OkCupid guys have come up with.
这是OkCupid上的⼈给出的图表。
40
And the important thing to notice is that it's not totally true that the more attractive you are, the more messages you get.
有⼀个重要的事要注意，你魅⼒越⼤，收到的信息就越多，这⼀点不全对。
41
But the question arises then of what is it about people up here who are so much more popular than people down here, even though they have the same score of attractiveness?
有⼀个问题，为什么处于图表靠上的⼈⽐靠下的⼈更受欢迎，即使他们的魅⼒值相同？
42
And the reason why is that it's not just straight forward looks that are important.
理由就是：不是只有颜值重要。
