来自主题: Military版 - 实数性质
我刚开始时没仔细,把小数部分当成到最近整数距离了。那样的话,就算稍微强一点的
结果用一下鸽笼原理很容易就证明了。要ka小数部分小于1/k的话,找一个比较初等的
证明貌似就比较challenging了。当然continued fraction和Farrey dissection也算比
较初等,所以还是有些初等证明的。

更强结果就是存在k改成存在无穷多的正整数k, 1/k改成b/k,这里b是黄金分割率。

(CNSNews.com) – President Barack Obama, as an Illinois state senator in
2002, said that using military force to topple a murderous dictator amounted
to a “dumb war” and should be opposed.
The “dumb war” Obama was criticizing was the planned invasion of Iraq and
the murderous dictator was its leader, Saddam Hussein. Obama, speaking at an
anti-war rally in Chicago on Oct. 2, 2002 said that while Saddam was a
brutal tyrant, that was not enough to justify usin... 阅读全帖

The economic downturn has not led to more crime—contrary to the experts'
predictions. So what explains the disconnect? Big changes in American
culture, says James Q. Wilson.
When the FBI announced last week that violent crime in the U.S. had reached
a 40-year low in 2010, many criminologists were perplexed. It had been a
dismal year economically, and the standard view in the field, echoed for
decades by the media, is that unemployment and poverty are strongly linked
to crime. The argument is str... 阅读全帖

For years now the climate campaign and the politicized science community has
been complaining that it has a “communications problem,” which can be
solved if only they shout louder, or get the human car alarm former Vice
President Al Gore to make an Oscar-winning documentary film or something.
Because, after all, it’s just so easy for a billion-dollar effort at
pushing the climate crisis to be undone by a handful of discredited “
skeptics” with only at tiny fraction of the resources environmenta... 阅读全帖

More than one in three of the unemployed workers in several of the largest U
.S. states have been out of a job for more than a full year.
Across the country, long periods of unemployment have been more prevalent
recently than during previous recoveries going back to the 1940s.
During 2010, long-term unemployment was disproportionately a problem in New
Jersey, Georgia, Michigan, South Carolina, North Carolina, Illinois and
Florida, according to Labor Department data expected to be released later

媒体界的左左们抓住这次挪威的例子,又开始控诉“右翼基督教极端主义恐怖分子”了
——Daily Beast出了一篇作文,一如既往的痛说革命家史、列出96年俄克拉荷马爆炸
案的凶手Timothy McVeigh、炸堕胎诊所的Eric Rudolph、还有在大屠杀记念馆扫射的
James von Brunn甚至明确推崇共产主义并痛恨小布什总统的那个撞国税局的Andrew
Joseph Stack,这些都成了他们口中的“right-wing, extremist Christian
terrorism”。问题在于,实际上这些人没有一个不反基督教的。
McVeigh明确宣称"Science is my religion," 他的遗言(引用Invictus)----"I thank
whatever gods may be for my unconquerable soul ... I am the master of my
fate: I am the captain of my soul."
Eric Rudolph仇恨堕胎,所以就信... 阅读全帖

来自主题: USANews版 - Maxine Waters Needs a Mirror
By Kevin Jackson
Queen of the poverty pimps Maxine Waters must so wish that Obama were a
whole white man. Democrat or not, if Obama were white, Waters would be
heaping all the blame on those frail little shoulders of his. But because
Obama has been presented as "authentically black," Waters was recently
forced to stop short of condemning him. Instead, she unleashed on the
closest white item she could find: the Tea Party.
Anything to keep her ignorant followers from actually thinking about whe... 阅读全帖

On Oct. 31, the U.N. Population Fund marks the arrival of the 7 billionth
person on Earth and raises the population estimate for the planet at mid-
century to 9.3 billion people.

There is a possibility, says the United Nations, that, by century's end,
world population may reach 15 billion. What does this mean for Western
civilization?

It may not matter, except to identify who inherits the estate. For while
world population is exploding, Wester... 阅读全帖

WARSAW, Poland (AP) — Of all the twists in Europe's debt crisis one of the
oddest must be this: Poles, Czechs and other eastern Europeans, long the
recipients of massive amounts of Western aid, are being asked to contribute
to an emergency fund for indebted Western European states.
That plan, decided at a European Union summit Friday, is sparking resistance
— and some outrage — from eastern Europeans who see a huge injusti... 阅读全帖

Almost 13 years ago, Mitt Romney left Bain Capital, the successful private
equity firm he had helped start, and moved to Utah to rescue the Salt Lake
City Olympic Games and begin a second career in public life.
Yet when it came to his considerable personal wealth, Mr. Romney never
really left Bain.
In what would be the final deal of his private equity career, he negotiated
a retirement agreement with his former partners that has paid him a share of
Bain’s profits ever since, bringing the Romney ... 阅读全帖

The New York Times
When Barack Obama joined Silicon Valley’s top luminaries for dinner in California last February, each guest was asked to come with a question for the president.
But as Steven P. Jobs of Apple spoke, President Obama interrupted with an inquiry of his own: what would it take to make iPhones in the United States?
Not long ago, Apple boasted that its products were made in America. Today, few are. Almost all of the 70 ... 阅读全帖
