# 用数学为爱情保鲜

16/5/22 数学的力量

###### 心得：

• 当你想研究一个问题的时候，总要先清楚，差距在哪里，什么是现状，什么是想要的状态；
• 原因是什么呢，都有什么样的因素，以什么样的形式影响着结果；
• 会有多大的概率可以使结果更好呢，有什么样的阈值。

Equations and symbols aren't just a thing. They're a voice that speaks out about the incredible richness of nature , and the startling simplicity in the patterns that twist and turn and warp and evolve all around us, from how the world works to how we behave.

###### 复述：

Hannah Fry tells a very interesting application of mathematics in the love.

She mentions 3 tips about the love.

Tip #1: How to win at online dating

Firstly, if you want to win, you should firstly get others attention,

it turns out that, how attractive you are is not the positively related to how beautiful you are.

in fact, the attractiveness is strongly decided by the spread of others’ opinions on your image,

the more different ideas others hold the more popular you will be.

Tip #2: How to pick the perfect partner.

In mathematics, there is a theory called optimal stopping theory,

it says that you should just reject everybody in the first 37 percent of your dating window,

And then, you should pick the next person that comes along that is better than everybody that you've seen before.

So there is a kind of romantic saying on the Valentine's Day card: My darling husband, you are marginally less terrible than the first 37 percent of people I dated.

Tip #3: How to avoid divorce

There is a finding that whether or not a couple is going to get divorced was how positive or negative each partner was being in the conversation.

And the influence that people have on one another, and in particular, something called the negativity threshold.

And these equations, they depend on the mood of the person when they're on their own, the mood of the person when they're with their partner, but most importantly, they depend on how much the husband and wife influence one another.

###### 词句：

just to put that into perspective－－我们好好思考一下这件事 I personally don't subscribe to such a pessimistic view－－我个人其实并不同意 这种悲观的看法 you're a massive minger－－你很丑 once you cash in and get married－－你一旦跳进婚姻 subconsciously,－－潜意识里 incredibly impressively simple and interesting－－不可思议太令人惊叹 的简单而有趣 mathematics is, ultimately, all about the study of patterns. the power of mathematics.
