扭腰时报:胖子说“这是一个非常非常美妙的事件” #ai1001
11月6日的文章:Thousands Chip In to Help Dissident Artist Pay Fine中提到:
“Some contributions have been small — symbolic, fractional sums of the
total — while others have totaled thousands of dollars. Mr. Ai said one
businessman offered him 1 million renminbi, about $157,000, but he turned it
down, saying he preferred to receive smaller sums. Mr. Ai has insisted on
describing the money as loans that he will repay.”

It is a common misconception that China, where the iPad is assembled,
receives a large share of money paid for electronics goods. That is not
true of any name-brand products from U.S. firms that we’ve studied. The
breakdown of value in these two iconic Apple products shows why.
First, our assignment of profits (which exclude wages paid) to first-tier
suppliers is based on the location of their corporate headquarters. There

《星际迷航》里的一艘星际飞船利用牵引光束拖拽一艘更小的飞船。科学家已经公开一
种与这部科幻巨制类似的牵引光束原型机
据国外媒体报道,科学家已经成功研制出可用于医学检测的牵引光束。研究人员表
示,尽管光处理技术自从20世纪70年代就已经存在,但这是首次利用光束把物体引向光
源,只不做这是在微观水平上实现的。
《星际迷航》和其他影片中显示,牵引光束是一种利用光束牵引飞船和其他大型物
体的方法。英国圣安德鲁斯大学和捷克斯洛伐克科学仪器研究所(ISI)的科研组表示,
他们制成的激光已经能让漂在水里的小球体移动。改变光的偏振方式,可以改变球体移
动的方向。他们还发现,在特定大小时,这些球体在移动期间会自动整整齐齐地排成一
行,在光的影响下跳跃前进。这种技术有望促使更加有效的医疗检测方法诞生,例如血
样检查。通常情况下,当物质和光接触时,固体物质会被光束推开,并被光子流带走。

I don't think it could be right.
1. tax bracket, I mean marginal tax bracket, not the average tax rate.
2. the person may have already caped the itemized deductible and beginning
phasing out (only a fraction can be counted) even without the donation.
As a result, the deductible is AT THE MOST the marginal tax bracket. I
think for most people, 15% is more proper than any guess above 25%.
Tax is not counted as the way you are saying:

傅苹自传造假一事,对美国社会来说,有没有新闻价值呢?当然有。傅苹并不是普通的美籍华人,而是美国公众人物。她是奥巴马政府商业部下一个国家咨询委员的委员,算是“奥巴马智囊”,去年刚被国土安全部移民局授予“杰出归化美国人”称号,其新书上了《纽约时报》畅销书榜单,她频频接受各大媒体访谈推销自己和书,所有这一切,都与其中美两重天的“人生传奇”分不开。现在其在中国的“人生传奇”被众多华人指出是捏造、虚构的,该公众人物的诚信遭到质疑,不值得报道出来让美国公众知道吗?
但是我给十来个曾经采访过我的美国记者写信让他们关注一下此事,只有一个回复说会留意一下。他们未必觉得此事没有新闻价值,很可能是觉得报道它属于政治“不正确”,有替中国说话之嫌——设想一下,如果是一本美化中国的畅销书被发现充斥谎言,美国媒体恐怕早就一哄而上了。倒是有欧洲和澳洲的媒体主动来联系我要做有关报道。英国两家主要报纸《卫报》和《每日电讯报》已较为中立地报道此事。

柴静《穹顶之下》推出后,有多名网友指出其中的数据、图表造假问题。这些指控,有的不成立有的明显成立,但都未见柴静及其团队做出回应。造假指控哪怕只有一条成立,学术声誉即破产。我在这里不想一一分析这些造假指控,只从该演讲视频的开头部分找出三处涉嫌严重造假进行分析。
为了表明她与雾霾的“私人恩怨”,演讲一开始,柴静就讲了一个感人的故事(1分09秒开始):
“她(柴静女儿)被诊断为良性肿瘤,在出生之后就要接受手术,做麻醉之前,医生对我说,她这么小的年纪做全身麻醉是有可能醒不过来了,你要有个心理上的准备,我还没有来得及抱她一下,她就被抱走了。后来护士在我手里放了一只小熊,那是用来安慰小孩的,她用来安慰我。”
在幻灯片上,柴静出示了这只玩具熊的照片(1分42秒),可以清楚地看到玩具熊衣服上写着:Make Surgery Bearable — JSEI Affiliates. JSEI是加州大学洛杉矶分校的眼科研究所,难道柴静是在眼科研究所分娩的?但是查该眼科研究所信息,有数十名眼科医生,并无产科医生,该研究所也无产房。

4月4日,最新一期的《纽约客》(The New Yorker)刊登了诗人特里林(Calvin Trillin)一首小诗,不过两个段落,28行。诗歌发表后,不仅作者没有想到,就连《纽约客》杂志的编辑也不会想到,这首题为《他们的省份怎么没完没了?》(Have They Run Out of Provinces Yet?)的诗歌,会在美国掀起一场事关中国饮食、中国文化进而上升到种族歧视的大争论。
作家加尔文·特里林(中)在纽约China Grill的一个派对上
美国的很多亚裔人士特别是华裔学者、作家纷纷撰文发表评论,对此提出批评,并对作者以及《纽约客》发表这样的诗歌表达不满。美国主流媒体对此非常关注,《纽约时报》和《华盛顿邮报》均在美国时间4月7日对此加以报道。
那么,这位诗人究竟写了什么?众人批评的焦点集中在哪里?有哪些值得我们关注的地方?
凤凰评论4月10日发表评论称特里林的诗其实与美国白人作家的传统一脉相承,即虽然夸赞了中国文化,但却忽视中国人的存在,还是有种族歧视的意味。评论也称,面对种族问题,华裔在发声。更多华裔站出来表达自我,追求自身的权利,这对推动美国社会的公平正义,改变华裔形... 阅读全帖

problem in China is people with access to power can get away with anything.
property tax can be evaded with fraction of the cost, through bribery and

minimum down payment can be short circuited by taking a loan somewhere else
to give as down payment, so you really financed 100% while conforming to the

Over the last few days imagery of what is claimed to be China's new stealth
fighter has appeared on a range of Chinese Internet sites. There have been
no official disclosures as yet, so many of the claims appearing in the media
may only be speculation presented as fact.
在过去几天里被称为是中国的新型隐身战机的图片在大批中国军事... 阅读全帖

New generation of unmanned spy planes is being tested
Three drones being flown in the coming weeks are speedier, stealthier
and higher-flying.
By W.J. Hennigan, Los Angeles Times
An experimental spy plane with a wingspan almost the size of a Boeing
747's took to the skies over the Mojave Desert last week in a secret
test flight that may herald a new era in modern warfare with robotic
planes flying higher, faster and with more firepower.
The massive Global Observer built by Ae... 阅读全帖

According to the U.S. Bureau of Labor Statistics, 20.3% of the U.S.
population is engaged in finance and insurance
19.7% of the United States labor force in 2002 was involved in guarding (
supervisors, security personnel, military). This is about the same as the
fraction employed in finance

AGENCIES, Jan 26, 2011, 07.22am IST
WASHINGTON: Indian-American Noshir Gowadia, a former B-2 stealth bomber
engineer, was on Monday sentenced by a US court to 32 years in jail for
selling American military secrets to China.
Gowadia, 66, has spent the past five years in prison. Prosecutors alleged
that the Mumbai-born Gowadia, who showed no emotions as the judge announced
the punishment, had helped design an exhaust ... 阅读全帖

China, Twitter and 20-Year-Olds vs. the Pyramids

Amman, Jordan
Anyone who’s long followed the Middle East knows that the six most
dangerous words after any cataclysmic event in this region are: “Things
will never be the same.” After all, this region absorbed the fall of the
Berlin Wall and the rise of Google without a ripple.
But traveling through Israel, the West Bank and Jordan to measure the shock
waves from Egypt, I’m convinced that the forces that were upholding the

原理:往地下灌大量富含各种有机溶剂、防腐剂、抗腐蚀成分的水,吸收天然气,然后再抽上来提纯。问题是抽上来的大约只有灌进去的一半,剩下的...全进地下水。hydraulic fraction技术已经在六个州全面铺开,最近几年发展神速。
污染:
一半废水进入地下水;地上浓缩的废水敞口蒸发;大量天然气和其他有毒气体直接泄进大气。
自来水泛黄、发黑、冒泡
地下水能点着火。溪流冒泡,插个管子能当炉子使
动物掉毛,鸟类、兔子、鱼类死亡
附近住户哮喘、癌变、周身疼痛、神经症状诸如丧失嗅觉和部分味觉,身体不能移动
官方态度:1. 水质测量没发现问题。2. 能源危机背景下,要有所取舍,顾全大局,退一步进两步。
审查:cheney在任上给这项技术立法大开绿灯,使其对任何环保法案免疫,同时不需要公开使用的化学成分。EPA更是连审查都管不着。直到2010年6月hydraulic fracturing使用的化学成分才公开,其中相当多的都是致癌物,绝育变异,不一而足。
最妙的是,绝大部分p民在认识到这项技术的危险性之前,都被开采公司拿钱买断,签了保密/免责协定。谁公开说这事儿,谁就法庭上见。
