The Crisis of the "Gentry Presidency"
By Joel Kotkin September 15 2011
Appearing in:
Politico
The Obama administration’s belated attempt to address the looming
employment crisis — after three years focused largely on reviving Wall
Street, redoing health care and creating a “green” economy — reflects not
only ineptitude but a deeper crisis of what is best understood as the “
gentry presidency.”

介绍一下此题的背景吧。
此题是证明Gamma函数的reflection formula中遇到的一步。
Gamma函数定义为,从0到无穷对x积分,
x^z/(xe^x),结果为z的函数,z为复数,可以通过解析延拓把该函数定义到全复平面。
Gamma函数的reflection formula是
Gamma(z)Gamma(1-z)=pi/sin(z*pi)。
我试证了一下,把两个积分integrand分别写为x和y的函数,然后积分乘积组合为二重
积分,再用换元法,
x=u^2,y=v^2,r^2=u^2+v^2,u/v=tan t,的方法,得到
Gamma(z)Gamma(1-z)=
2 integration 0 to pi/2 of (tan t)^(2z-1) dt。
当z=0.5+ib时,积分应该给出reflection formula所给出的值。这就是此题的来源。

对RCS的理解似乎不对.并不是简单的等效一个平板的面积.
根据wiki:
http://en.wikipedia.org/wiki/Radar_cross_section
"
Informally, the RCS of an object is the cross-sectional area of a perfectly
reflecting sphere that would produce the same strength reflection as would
the object in question.
"
也就是同等反射效果的球的截面积.
http://www.afwing.com/intro/stealth/1.htm
这个文章是晨枫谈隐身的,写的很好,也可以参考一下.
里面对RCS的定义是一致的:
"
这里,雷达反射面积不是目标的几何截面积,而是一个与目标产生同等回波的金属圆球
的等效截面积
"
同一个文章里同时提到F22的RCS是0.0065m^2.
3.14*x^2=0.0065=> x=0.045m=4.5cm

How does a laser speed gun work to measure a car's speed?
If you have read the article entitled How Radar Works, then you know how
normal radar works. A normal radar set sends out a radio pulse and waits for
the reflection. Then it measures the doppler shift in the signal and uses the
shift to determine the speed.
The new laser speed guns use a more direct method that relies on the
reflection time of light rather than doppler shift. You have probably

It reflects how good you are - as a trader, not as a person.
Anyway, (as far as I understand) the point is not what
our bottom line reflects, but that we don't want to let the reflection
get into our trading decision process, because once that happens,
as it did to the guy in the story, we are no longer trading but instead
trying to prove "I was right".

again, it should be made clear that town appraisal/assessment value is not
a true reflect of market value, bank appraisal value is NOT a 100% reflect of
market value although it's close. in most cases, bank appraisal will not result
in price lower than what you offered because 1) the offer price
should be close to the market value, 2) they want to give you the loan.
the true market value is actually reflect by your offer, which should be
determined after comparing to prices of recent similar pro

a couple of points:
I think LZ need to do some serious reflection before she/her own behavior
would damage her own child more than anybody else...
I don't know what's really going on but as far as I could see, it is
clearly she is very aggressive and perhaps somewhat spoiled herself, and
take a lot of things for granted...I don't see how she execute self-
reflection, disciplines, and respect, nor respect others, rules or authority

MIT is asking students, faculty, and staff to collectively pause and reflect
Monday after the death of an undergraduate this week, the sixth death of a
member of the university community in as many months.
“The community here at MIT is in pain,” chancellor Cynthia Barnhart said
by phone Friday. “We’re asking everyone at MIT to do something we [often]
don’t do here, to stop.”

She said that at noon Monday the university has scheduled a first-of-its-

Harvard has a million ways to get a diversified student body. for example,
family income, or like texas, top 10% of each high school, etc. however,
skin based enrollment is purely racist.
merit may not reflect an appliant's talent well. but it is fair. are you
implying that skin color can reflect applicant's true talent and ability?
thanks for your reasoning in Harvard and other ethnicity's shoes. I heard
that many times already, but I still love my own kids way more than Harvard

Are We Overpraising Our Children?
The negative effects of overpraising kids
Posted Dec 10, 2013
Research has shown that there are positive effects of praising children, but
it depends on what kind of praise we’re dishing out. A recent Stanford
Study (link is external) of toddlers showed that “praising effort, not
talent, leads to greater motivation and more positive attitudes toward
challenges” down the road. These findings are consistent with previous
research, which has connec... 阅读全帖
