QUANTUM SPACE ELEMENTS (QSE)
INTRODUCTION
This is a non-mathematical proposal introducing a cosmological model that is
cyclic, deterministic and infinity-free. For the purpose of achieving this
objective a number of new concepts are introduced. The framework of this
proposal is structured over a number of assumptions, leading to various
considerations of cosmological concerns. Furthermore, verification methods
are suggested of both, observational and mathematical nature.

The first private spacecraft aiming to dock with the international space
station blasted off from Florida and reached orbit early Tuesday with split-
second precision, but the biggest tests for the mission are still days ahead.
The predawn skies around Cape Canaveral filled with the bright glow and deep
rumble of Space Exploration Technologies Corp.'s Falcon 9 rocket lifting
off the pad, carrying an unmanned Dragon spacecraft on a highly anticipated
test flight scheduled to last about two weeks.... 阅读全帖

今天请了David Yee帮忙做inspection,各方面都挺好,就是发现crawl space里靠近
外墙的地方有一小摊积水,其实也不能算积,就是稍微有点水,周围土壤都很潮。
里面装了一圈排水管道,David说这种情况没关系,因为靠着外墙,下雨后水渗进来很
正常。
看了精华区的文章心里实在不放心,想问一下这是正常情况么?严重程度如何?

No one seems to know much about the Air Force's X-37B secret space plane
except that it appears to be working exactly as designed. The unmanned
Boeing-built craft, which resembles a miniature space shuttle, returned to
Earth on Friday after nearly two years — 674 days, to be exact — in space.
It's the X-37B program's third mission to space and by far the longest.
The plane landed at 9:24 a.m. local time on Oct. 17 at Vandenberg Air ... 阅读全帖

今天孩子带一个space shuttle的图片去幼儿园,之前带过space shuttle 玩具,现在
他每天想的画的都是space shuttle,大概持续了2个月了,培养他的这个爱好是他父亲
每天睡觉前给他讲space shuttle,而且孩子每天从电脑上看space shuttle(看电脑现
在只有周末同意看了),其他的没有爱好了。我记得很小的时候他非常喜欢看火车,也
持续了很长时间。
今天老师问我:为什么你的孩子那么喜欢space shuttle? 其他的都不敢兴趣,再说语
言不通,我想他在课堂上大概每天也在想space shuttle,这样下去,其他方面的知识
根本培养不起,当然也包括语言。我打算让他爸爸停止讲space shuttle.
有没有遇过类似问题的爸爸妈妈们?都是怎么解决的?

我不清楚Craw Space的一般构造。我是根据自己家房子的Craw Space构造得出的个体结
论。
我家Craw Space有两个排水口,其中之一附近安装了Sump Pump,另外一个排水口是自
然排出的。
下大雨的时候,Craw Space的低洼处明显有积水,且积水很高。且可以看到积水慢慢通
过排水口排出,也能听到Sump Pump有节奏地在工作。
在拿到Inspection Report的时候,我问了Inspector要不要安装第二个Sump Pump,也
问了Constractor这个问题,但答案都是不需要。
楼主的问题:首先要检查Craw Space有没有排水口连通下水道?如果有这样的排水口,
且已经安装了一个Sump Pump,Craw Space至少具备一定的排水能力。当然,这个问题
,还是应该听取Inspector和Constractor的。
我在Corvallis,Oregon待过。那里下雨确实很多。但Craw Space的积水担忧,主要还
是看是否能抵抗频繁的大暴雨的排水。

来自主题: Seattle版 - 开个贴说说crawl space进水
说到sump pump就说到了解决办法~ 现在的解决办法,就是在crawl space里面,顺着
foundation/footing 挖沟槽,埋下perforated pipes,砂石,把侵入的水引到crawl
space最低的地方(在crawl space里面,我也见过一次在foundation 外面房子一角的~
),一个四五十加仑的container,里面一个pump, 有个浮标,当container的水升起来
,浮标上浮,启动马达,把里面的水抽出来,噪音么,其实很小,抽水的时候就想
flush toilet的声音,还好更小一些。
有的,因为地势,不需要sump pump, crawl space里面的drainage导到最低得一角,就

1GB(严格的说好像是896MB)的kernel virtual addr space跟physical mem是one-to-

就是让表格高度增加。
\renewcommand{\arraystretch}{x.xx}
..where "x.xx" is a line spacing, well, actually it is what the current line
spacing is multiplied by before it is applied to the table lines (default
is "1"; in single space mode, to double space the table enter "2", for 1.5
spacing enter "1.5", etc.; in double space mode, to single space a table
enter "0.5", etc.). xx can be "cm", "in", etc.
还有就是如何增加表格标题与表格的距离

我的暖气管道,水管道都是从utility room通到一个crawl space里面,再转折向上通
往living room和kitchen之类地方的。我发现我的crawl space有一个小窗口连通外面
,尺寸大概6×12英寸,sump pump的管道就从那里通出去(sump pump也在crawl space
里面),这个窗口有一个小纱窗。请问这个窗口是不是同时还有透气的作用,不让sump

但是这么冷的天里面crawl space很冷,白白浪费很多暖气,请问可不可以把这个窗口

I think maybe he means the space of 1-dim random variables? this is not a
probability space itself. but it is a hilbert space if you define the inner

标 题: user virtual address space VS kernel virtual address space
发信站: BBS 未名空间站 (Sun Apr 18 17:14:09 2010, 美东)
32-bit machine,virtual address space 4GB,kernel(e.g. linux)会把这4GB,分成
3GB user/1GB kernel。
1GB kernel virtual address space跟物理内存是1-to-1的map。对user virtual addr
做virtual --> physical 转换是也是转到一个kernel virtual addr再到physical
memory。
那这样不是只能用到1GB physical memory,如果有更多
的就用不到了。windows也有这个机制,好奇这样的话不是加内存都没用?大牛给解释
一下啊

这个问题问得好。
Malloc 一般可以从两个地方得到 address space. 一个就是 heap.
address space 是通过 brk 系统调用来调整 heap 的最高可用的
地址。但是 brk 可以扩展的有限,至少在 x86 是这样。
另外一个地方就是通过 mmap. mmap anonymous page 就是可以
获得新的可以用的 memory.
但是这个和系统的 memory 又是另一回事。对 kernel 来说,
kernel 看到的是 raw pages. 这些 page 可以根据需要 bind
在某一个 virtual memory address space 里面。这个 binding
不是固定的。 kernel 可以把 某个 process 的 page unmap
出来用干其他的事情,等那个 process 用到那个 page 才产生
page fault, kernel 知道去什么地方把那个 page 内容从新搞
出来。一般是在某个文件,如果是 file backing, 或者是 swap
file 如果没有 file backing.
所以这里有... 阅读全帖

Scientists are one step closer to predicting space weather.
by Vanessa Thomas
Someday soon, space scientists would like to be able to issue "space storm
watches" just as meteorologists announce thunderstorm or tornado watches
today. With the help of a sun-studying instrument in Alabama, scientists are
getting closer to identifying the warning signs of potentially hazardous
space storms.
Severe space weather can cause havoc just as severe weather does on Earth.

Next-Generation Space Telescope Chosen to Peer Into Past
By WARREN E. LEARY
WASHINGTON, Sept. 10 NASA chose a successor to the Hubble Space Telescope
today, announcing that it would launch a next-generation space observatory in 2010
that would study light produced in the earliest days of the universe.
The space agency selected TRW Inc., of Redondo Beach, Calif., to lead a team that will build
the observatory, which will be called the James Webb Space Telescope in honor of a
pioneering NASA

Explanation: At about 100 meters from the cargo bay of the space shuttle
Challenger, Bruce McCandless II was further out than anyone had ever
been before. Guided by a Manned Maneuvering Unit (MMU), astronaut McCandless,
pictured above, was floating free in space. McCandless and fellow
NASA astronaut Robert Stewart were the first to experience such an
"untethered space walk" during Space Shuttle mission 41-B in 1984.
The MMU works by shooting jets of nit

那你说该怎么办?
I am sure that a separable Banach space can be a probability space,
so I believe a probability space must be a Banach space,
but I don't know how to prove it.

Women think that men are worse drivers, and men think that it’s women who
can’t drive very well. The South Korean government is clearly siding with
men in this debate, with news of the introduction of so-called “she spots”
to its capital city Seoul.
These she-spots take the form of parking spaces specifically aimed at and
reserved for women drivers. The lines are pink, they have a female in a
skirt symbol painted inside them, and they ar... 阅读全帖
