"Mr. Curiosity"
Hey Mr. Curiosity
Is it true what they've been saying about you
Well are you killing me
You took care of the cat already
And for those who think it's heavy
Is it the truth
Or is it only gossip
Call it mystery or anything
Oh just as long as you call me
I sent the message on did you get it when I left it

It wasn't meant to mean no harm

懵懂的大学(之十一) :Curiosity kills cats
作者:沧海一声笑
谨以此文献给过去的岁月,和我的朋友们。
本文纯属虚构,如有雷同,纯属巧合。
(11) :Curiosity kills cats
这一天,我在录音社当班。坐在柜台旁边的桌子前。一边背着托福单词,手中的圆珠笔打
着旋儿。自从陈平参加了托福班以来,我们每个人都人手一册托福六百分词汇。
门扒打一声开了。一阵香风钻到我鼻子。我打了个喷嚏。待我抬眼一看,来人已经站到我
的面前。我定睛一看,差点从椅子上掉下来。活脱脱的又一个秋儿站在我眼前。
我只所以说“又一个” ,当然我知道她并不是秋儿。我第一个反应是:秋儿派来的间谍
,转瞬又把这个念头打消了。她朝我点了点头,微笑着问:
“你有谭泳麟的录音带吗?”
这个时候,我可以看到她细密的白牙,还有两个小虎牙,酒涡忽隐忽现。我想知道这酒窝
什么时候会浮出来,什么时候会隐下去。秋儿也是这样。
“有,我们有谭泳麟所有的带子。” 她说话时眼睛还眨呀眨的。
我递过来录音带目录,翻到谭泳麟的一页。谭泳麟也是我喜爱的歌手。
她低下头,一个一个的看着。
“好,就来这个。” 她指着“爱在深秋

If you could submit just one question to be asked of President Obama during

of debate hosts and moderators would ever actually ask your question, as you
framed it? Your answer, I am sure, is almost as self-evident as is the

我觉得把心理学理论应用到实践的时候,要注意海森堡测不准原理。换言之,实践上的
观察不可能准确。而忽视这种观察误差,有可能造成 over-interpretation 而老军医
化。
或者作为实践的冰箱贴,目前的心理学,在实践上,不是用来分析健康人的健康状态的
,实践的被分析对象,至少呈现某种 temporary fatigue / disorder。
否则对实践上的正常人所谓的分析,容易要么陷入 over-interpretation,要么陷入
theory of nothing,总之对实践没有任何指导意义。
或者这么说,是药三分毒,给健康人下药,希望多吃补药能更健康,这多半就是老军医。

“《中国合伙人》最终剧本只用了我剧本的18个字,中国合伙人、新梦想学校、还有3个主角名字,这使我很‘愤怒’。”日前,真格基金创始人、新东方创始人徐小平道出了自己和电影《中国合伙人》之间的一些轶事。与俞敏洪此前针对电影《中国合伙人》的有礼有节的回应不同,徐小平的讲述可谓天马行空,里面夹杂了自己对中国梦的个人解读。以下为徐小平自述全文。
口述:徐小平
整理:王根旺
《中国合伙人》的确是根据新东方的原型改编的,成东青就是俞敏洪,王阳就是王强,孟晓骏也可以说是陈可辛。这个剧本初稿确实是我提供的,大概一年之后陈可辛把剧本给我看,他改了很多只用了我剧本的18个字,中国合伙人、新梦想学校、还有3个主角名字,这使我很‘愤怒’。有一段时间,陈可辛还想把“中国合伙人”改成“中国先生”。
为什么写《中国合伙人》?
我写这个剧本和今天的演讲主题也相关。小时候,我对文学感兴趣,但那时是文革时期,没什么可干的,我就背唐诗宋词,差点成了神童;中学毕业以后,我拉起了小提琴,上了中央音乐学院。我从事音乐研究,做学生会干部,是学生会的文艺部长,然后我就被调到北大,成为北大的艺术团长,实际工作就是和学生打交道,做学生活动,... 阅读全帖

“At 2.5 billion and counting […] it's a hell of a neat trick that NASA
just pulled off, and it's sure to generate a lot of amazing video. And yet,

are you sure she's no-sexual experienced?
seeing most replies here, I just feel most people here know nothing about
china's young people today. such gay/les/exposure/soft porn themes are simply universal in a lot of
websites in china nowadays, by which kids and teenagers are facing everyday.
btw, curiosity is human nature. Your niece might be accidentally exposed to such pervert film once (either by
browsing web sites or solicited by other teenager friends), and then got indulged into it and fee... 阅读全帖

来自主题: Investment版 - Financial Porn: Are you Susceptible? (zz)
Curiosity is a gift. It enables us to learn, explore and grow. So let’s be
honest: How many of us have had our curiosity aroused by financial media
who make breathless investment predictions and promises that sound like they
came straight from Merlin’s crystal ball?
We thought so. We’re human, too.
But a word of caution: While financial media prognostication and investment
advice are not always wrong, they often fall into the category of “
financial porn.” Emmy-winning personal finance commenta... 阅读全帖

我觉得啊,娃有兴趣是多好的事情啊,小孩最珍贵的东西就是curiosity,要鼓励而不
能禁止。我是不会禁止任何和curiosity有关的行为了,除了和安全有关的会严厉禁止
之外,其他都是鼓励。所以我娃现在虽然很小,就很懂事,很明白。从10个月开始下
楼梯滑滑梯都很安全,知道趴着滑才不会撞到脑袋,丢桌子上床上坐着都不担心掉下来
。我家娃15个月(现在16个月),不但可以用勺子吃固体,液体也可以吃个70-
80%。我们也没有特别训练,只是她想就给她,舀歪了就帮忙扶下她的勺子,而且她
要拿筷子吃我也给她,她第一次用就知道要把筷子打开去夹。10个月的时候就会握笔
。。。。我们阿姨说是我娃天生精灵。

了。

Drive 娃学习的第一动力是 curiosity。楼主的故事,娃第一时间就知道了答案,
娃还能有 curiosity 么?
娃心里肯定在想:“俩白痴给俺讲白痴故事不算,还问白痴问题。。。俺这么忙,
搞得俺很烦的,知道不知道?”

1. Introduction
My interest in studying creativity was inspired by the frustrations that I
felt as a student, then as a professor. I wanted to know how I could
encourage creativity in myself, my students, and my colleagues.
Politicians, industrial managers, academic administrators, and other leaders
often say that innovation is critical to the future of civilization, our
country, their company, etc. But in practice, these same people often act as
if innovation is an evil that must be suppressed,... 阅读全帖
