p*********8 发帖数: 1039 | 5 多谢回复,我再把问题确认下
我们统计系秋天会开 probability thoery,8000以上的level, 是统计phd的核心课
者们课据说比较难,有人建议我在上这课之前先修real analysis, 这是数学系
6000level
的课。
我的问题是,
这个probabilitys theory 是不是大家说得 measure theory?
如果不是的话,是不是有专门的课叫measure theory
real analysis 是不是上 probability thoery 这课的基础?
另外顺便问一句,我和louzhu 的基础差不多,所以想问,若是要上phd,还有什么数学
课要补吗? |

f********g 发帖数: 770 | 10 另外,关于sex,sexuality还有gender的问题,有一个人不能不提,就是Judith Butler
,她在这个问题上比福柯走的更彻底,认为人的社会性别(gender), 生物性别(sex),
还有sexuality(性取向,性行为),统统都是话语体系的产物,是话语体系作用于人
,然后在身体场面上表达出来的一种performance。人人都在演绎自己的性别,而这种
演绎是被置于一个heteronormativity的话语空间之内的,所以很多人从一开始就被
dehumanized,因为在这个话语空间里面,是不容许有homosexuality的存在的。所以她
认为gender, sexuality都是被话语建构的,所以也是一个连续的,开放的结构,因此
是可以被改变的。她也被认为是Queer thoery的奠基人。
她自己是犹太人,还是lesbian,被称为是Hegel在当代的继承人,在美国学界(几乎各
个人文社科领域)都非常有影响力,以至于美国法院在判案的时候,常常要引述她的学
术文章作为依据。 |

On the other hand, we are more confident in theory 1. The chance for thoery
1 to be falsified seems much smaller than theory 2. That's why we have
confidence in buy&hold. The time frame of economic cycles and market
response may or may not be affacted by a lot of factors (other than human
nature-greediness). For example, I may argue, information is spreading
faster, the market becomes globally |

s******1 发帖数: 729 | 25 今天是最后一天的钢琴考级,忙碌的一天终于结束了。
早上我做room monitor,下午改了一下午的theory,各级都有。发现level越高,错误率
越大,有的小孩有些概念是混淆的,比如figure bass就是很多人出错的地方。考卷中
中国孩子占很多,基本做的都不错。
其实,在平时的训练中,就应该注重技巧的训练,理论概念的清楚,还有养成良好的
sight reading 习惯很重要。用30 seconds去快速扫描整个段落,在键盘上找到音符弹
奏的位置和按准确的节奏弹奏,都会提高整体试奏能力。相对来说,ear trainning 在
整体thoery test中占分不是很多,对各level来说相对来说容易地多。
今天又看到了熟悉的隔音壁,一间间窄窄的琴房,各个琴房里传来的阵阵熟悉的奏鸣曲
,练习曲,巴赫作品时,好像又回到了大学时代,是一种亲切和久违的感觉。虽然自己
早上5点(旧点)就爬起来了,很累,但是听到考生弹奏的时候,仍然觉得很享受。
很多家长和孩子们都可以放松和休息一下了,祝每位考生都能取得理想的成绩。 |

p******a 发帖数: 975 | 29 我的想法是这样的,欢迎chem老师来探讨一下。
2bb open的话就给BB一个非常好的odd。call 1bb to win 3.5bb pot。假设BB的牌是
Q3o,flop hit pair Q和2 pair+的概率接近20%。这本身就是一个+ev call了。同时因
为pot很小,意味着如果用45s,22之类的牌call的话imply odds很大,fold equity很
高。如果再考虑前面的位置也有人call的话,BB几乎可以+ev无脑call任何牌。同时
late position比如button可以非常cheap的3bet bluff,然后利用position玩postflop
。也使得early position opener很难打。根据thoery of poker,玩牌赢钱的方法是让
对手make wrong move。所以除非对手非常tight,不停fold to 2bb open(wrong move
),否则是很难赢钱的。
5bb open涉及到open range的问题。我也没有太想明白。极限的情况比如hero只open

The empirical /utilitarian based arugement works for religion as well.
The "100 authors against Enstein" is just an counter-arguement to your "

Agree.
"Intelligent design" is not suitable to teach at K-12 level. Nor is "

atheist belief into our kids, although the scientific theory itself (the
true science part) is not for nor against Christian belief. |
