回版主MM,Divergent归类于young-adult dystopian novels,是现在比较流行的Young
Adult的文学系列之一,都是非常有名的畅销书,而且都已经改编成了电影。
The giver (1993) social science fiction children's novel (generally Young
Adult or older) 这个是94年的Newberry得主
The Hunger Game (2008)adventure novels
Maze Runner (2009) young-adult post-apocalyptic dystopian
Divergent (2011)young-adult dystopian novels
The giver我还没看过,但是其它三个都有比较明显的亲密场景,这些在HP和LOTR里都
是没有的。

The Road Not Taken
Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;
Then took the other, as just as fair,
And having perhaps the better claim,
Because it was grassy and wanted wear;
Though as for that the passing there
Had worn them really about the same,
And both that morning equally lay
In leaves no step had trodden black.

现代诗,根据我的浅薄理解,的一个重要内涵是:自由。看到上一句,你永远也想不到
下一句。整首看完,你能体会一个自由的灵魂在字里行间呐喊,无拘无束。至于这个灵
魂是浮躁还是沉郁、是抑郁还是欢快,诗句是如画还是如歌还是丑陋,都不重要,各自
有各自的美感。
从这个角度看,现代诗突破了“意境”这样一个纯技术的的境界,能够直接打击人心。
举例来说,古体诗描述乡村,好句子很多(很多好句子也体现“自由”)。然而现代乡村
诗可以全然不同、更加广阔。现代“乡村诗人”里我比较喜欢Rob Frost,比如他著名的

我来补充补充物理的方面吧
说白了就是因为
1.我们不知道为什么有electroweak symmetry breaking
为什么是你说的100GeV
到底有没有Higgs,有了Higgs就有了quardratic divergence的问题
比如你算higgs的propogator,一圈有个top quark loop的修正
是cutoff^2发散的,(SM 其它的很多ln的)
susy的介绍,因为有了superpartner,是scalar正好和这个fermion的loop 正负号不同
所以消调了
你也可以算gauge loop这里也有gaugino的消除
所以susy可以说stabilize了higgs的质量
当然现在也有人做什么little higss企图解决这个问题
不过那个只能消除一圈的quadratic divergence
当然了就是在SUSY里
我们还是不知道为什么有个ELECTROWEAK SCALE

Explanation: The 2001 Leonid storm was so intense that the meteor shower's radiant, the
point on the sky from which the fleeting trails seemed to diverge, was easy to spot. But the
bits of debris that created the meteors really moved along parallel paths, following the orbit of
their parent comet Tempel-Tuttle. Their apparent divergence from the shower's radiant point
was simply due to perspective as sky

There are several ways to define the distance measure between
two n by n SPD matrices.
(1) Easiest: just treat them as n by n symmetric matrices
and use the inner product on the space of n by n symmetric
matrices which is a vector space of dimension n*(n+1)/2
(2) From statistics point of view, think about the distance/
divergence between two normal distributions with same
mean but different covariance matrices.

theory, the divergences can still be there when you use other expansions.
in some cases, the divergences of certain diagrams cancel each other.

西方国际社会学(或称全球社会学)的蓬勃发展,略迟于西方发展经济学和发展政治学的发展。五十年代和六十年代,帕森斯的社会发展理论占统治地位。七十年代,社会现代化理论、依附论、世界体系论,影响广泛。现在,只有世界体系论硕果仅存。主要代表人物有颇郎伊、艾森斯塔德、墨尔、佛兰克、斯卡齐波尔、梯利、傅高义、林茨、蔡斯-丹,而影响最大的是沃勒斯坦。在亚欧非世界大体系中,中国第一长达一千多年,欧洲是边缘。1865年前后,英国产值超过中国;1900前后,美国产值超过英国;中国成了边缘。今后几十年内,中国产值有可能超过美国,并长期保持第一。果如此,则中国第一就是人类世界体系的常态。

你这支股票是MACD金叉里最少见,也是最reliable的一种。
A Positive Divergence occurs when MACD begins to advance and the security is
still in a downtrend and makes a lower reaction low. MACD can either form
as a series of higher Lows or a second Low that is higher than the previous
Low. Positive Divergences are probably the least common of the three signals

第四章主要讲了一些技术指标。这些指标主要分为3种:顺势指标、摆荡指标与杂项指标。虽然有些朋
友说这是一本入门书,但是我却觉得这章对我有些难度,或者说有些枯燥的感觉。
顺势指标相对来说简单一些,比较容易懂,这些指标适用于趋势比较明显的行情。但对于横向走势,
它们所提供的讯号并不理想。不过我倒觉得对我这种初学者来说已经够了,我又不靠它吃饭,看多了
反而消化不了。我主要看了三个指标,移动平均、MACD(Moving average convergence-
divergence,移动平均收敛发散指标)、MACD柱状图。其它的看着头晕,呵呵。可能以后再读的时
候会有感觉吧。
移动平均(moving average,简称MA)比较简单,但是它没有考虑权重的问题,而指数移动平均
(exponential moving average,简称EMA)是一种比较理想的顺势工具。它给予最近资料较大
的权数,对于最近价格变动的反应快于简单移动平均。我想今后我在看K线图时会应用EMA的,看10
日均线和30日均线的关系来与预测股价的走势。这是我看书时的感觉。
但是我看到作者介绍MACD时,(移动平均收敛发散指... 阅读全帖

就是那种幻想近未来,Kickass girl的故事。
这种剧一般拍得都很糟糕,而这部却还不错。比那个hunger games强不少。
那个hunger games是从日本的大逃杀抄来的,本来很严肃的作品,一下改通俗作品了,
还是很琼瑶的那种:三四个男人都看上了女主——现在连超级英雄片都不好意思这么编
了——虽然这戏以女性观众为受众,可是也不必这么露骨吧。
另外那戏有些东西太假了,比如剧里没有超能力,可是女主居然在基本靠体力的游戏里
屡屡胜出(尽管编剧尽量往女主智勇双全上靠,可是实际那就是个靠冷兵器作战的事情
,女主再智勇双全,也不可能胜出的,比如你体重比对方差50磅,你怎么可能搏斗获胜
)。
对比下本片,女主搏斗始终一般,就要更符合现实(毕竟不是有特异能力那种片子)。
说回这个divergent,这剧编剧肯定是个小左。又是集权要控制自由,集权要把人分为5

1. DOW and SPX 都探测2002年底部
2. Dow的fib retract点位非常有意思。看图。
3. 从5月19号开始,到11-21,很典型的5波。其中第四波的8500-1000平台整理更是典
型。
4. VIX现在double top,RSI negative divergence。
5. It is already the worst year in history,worse than 1929.看图。
Seasonally,it favors bulls here。
6. Dollar很有意思,现在是一个三角,不过RSI和MACD都指向向下突破。石油和
commodity板块占spx比重最大。
7. SPX日线MACD positive divergence。CPC目前五日均值1.18,very high level。
