means the sqrt of the sum of squares of components
and the norm of a matrix is defined as the Sup_{|v|!=0}
(|Av|/|v|)and this is in fact the eigenvalue which has the largest absolute

面临不同的possible outcomes的时候,你愿意take的risk是什么。如果两个risk的概率
完全是一样的，你更愿意take哪个。
举个我上课的例子吧
有一个人医生让她接受器官移植
如果接受移植作手术，10% risk手术出事，死掉，90%成功，5% risk 一年后器官继续
fail，然后靠机器。但是这个有90%*（1-5%）的概率可以继续好好活几年。
如果不接受移植，2% risk 器官一年内fail死掉，30% risk器官一年内fail但是靠机器
可以维持活。这个虽然立刻死的概率小些，但是low quality of life的概率比较高。
最后权衡就看在个人心里那个比较重要了。没有对错，只有选择。但是在一个人确定了
自己的weights on different outcomes以后，最优解是有的。只是每个人都不同。

誤，其中，鄧小平發揮決定性的作用。然而，卻無專文探討鄧小平當年在此
事中所扮演的角色和作為。本文的論點為：基於毛澤東的授意、鄧小平自身
與軍隊的淵源，以及其職位上與軍務的聯繫，鄧小平對於軍中發起的「反教
條主義」，了解知情外，其態度傾向支持，甚至頗為激進。在毛澤東的囑咐
下，鄧小平更介入1958 年中央軍委擴大會議，強勢地驅策主軍的彭德懷改
變會議的議程，掀起「反教條主義」的最高潮。鄧小平在肯定會議批判方向
的前提下，僅出面保護其昔日戰友劉伯承，使之免遭劫難。經由本文的討
論，亦能對其他若干流行的中共黨史觀點，提出有別既往的思考和啟發。

然后电影里妹纸开始示好也无效，原因是 binomial classification 是 classify 的

能接受最重要。
另外男生的性欲不太会中年增加。更多的情况是之前打飞机，女生不知情。
但在中年以后，由于 oxytocin pathway 开始退化，所以造成中年危机感，怕
oxytocin pathway 不足而影响夫妻之间的 bond，抗拒小三能力减弱。
所以中年反而放弃打飞机，改成双人性爱交公粮。这个可以理解也不是坏事。
技巧上面建议两人探讨试验实践，选择更能让女生开心的体位技巧，还有情趣辅助玩具
辅助爱液等等。同时建议更多考虑比较 relaxing 的体位，如果性爱次数时间增加的话。 |

It’s too soon to know whether a Chinese researcher who claims to have
successfully edited the genomes of newly born twins is telling the truth.
But if he is, and if the girls turn out to be healthy and normal, it heralds
a significant change in the scientific and ethical status of human gene
editing. The outrage might not last long.

Ever since the 2016 election of U.S. President Donald Trump, our little

The latest browbeating is being delivered by China in its calculated

Women with larger breasts are more likely to develop breast cancer, scientis
ts believe
A study of more than 16,000 women found those with a larger bra size were at
greater risk of the disease.
The link could be down to the sex hormone oestrogen that can trigger the gro
wth of mammary glands and tumours.
The researchers found seven genetic factors significantly associated with br
east size - three of which are strongly correlated with mutations already li

我看到f-16.net上有如下讨论:
"
The oxygen system has a diluter lever with two settings: NORM and 100% O2.
In the NORM setting, the amount of oxygen delivered is dependent on the
cockpit pressure altitude. As the cockpit altitude increases (less pressure)
, an incrementally higher concentration of oxygen is delivered. The 100% O2
setting delivers pure oxygen and is generally used when the Emergency Power
Unit(EPU) is running, all cockpit pressurization is lost or when smoke or

1. Don't over-estimate yourself. The norm of a society changes over time. It

the information/education you have afterwards. Put yourself in cultural
revolution, what makes you think you are more rational than others?

going to report is a true crime. " You really think there is always a
simplistic clear cut? You sure what you do right now won't be considered as
sin 50 years later?
2. You are the one busy calling and using so-called societal norm, ok?! I
said many of those norms are temporary, we should fall back on the
fundamental virtue of mankind instead of some temporary "poltical
correctness", such as prostitution is sin. What you sai |

America has been creeping closer and closer to allowing women in combat, so
Wednesday's news that the decision has now been made is not a surprise. It
appears that female soldiers will be allowed on the battlefield but not in
the infantry. Yet it is a distinction without much difference: Infantry

A good shower is one of life's simple pleasures. Until it gets interrupted

If you like your shower, you probably can't keep it once the bureaucrats are
done. The War on Women and Men Taking Showers began with a 1992 law that
restricts how much water can flow through each nozzle. In 2010, the feds
cracked down against multiple-nozzle showerheads. Now the EPA wants to limit
