16/5/22 數學的力量
心得：
數學的力量是很強大的，它存在于我們的生活中，影響著我們的生活，無處不在。
說得簡單一些，數學就是一門研究pattern的藝術，我們試圖用公式和方程去描述自然中生活中的規律，而且這個式子越簡單越好。
這個演講中，舉了一個用數學去尋找愛情的例子，
其實也說出了用數學去構建模型，去思考，去解決問題的三個比較簡單但是普遍的模式，就是：
差，概率，因果
- 當你想研究一個問題的時候，總要先清楚，差距在哪里，什么是現狀，什么是想要的狀態；
- 原因是什么呢，都有什么樣的因素，以什么樣的形式影響著結果；
- 會有多大的概率可以使結果更好呢，有什么樣的閾值。
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.
復述：
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.
妻子或是丈夫是如何去回應 他們下一段對話， 他們的積極或消極程度是多少。
這些算式，取決于 當他們獨處時各自的情緒， 當他們和伴侶在一起時候的情緒， 但最重要的是， 取決于丈夫和妻子相互間的影響。
詞句：
just to put that into perspective－－我們好好思考一下這件事
I personally don't subscribe to such a pessimistic view－－我個人其實并不同意 這種悲觀的看法
you're a massive minger－－你很丑
once you cash in and get married－－你一旦跳進婚姻
subconsciously,－－潛意識里
incredibly impressively simple and interesting－－不可思議太令人驚嘆 的簡單而有趣
mathematics is, ultimately, all about the study of patterns.
the power of mathematics.
