January/ February 2010
The Atlantic's James Fallows reacts to fears of American decline, pointing
to unwarranted cries of imminent doom throughout American history, but also
worries that the system of government needs fixing in order for the U.S. to
maintain its strength.
Since coming back to the United States after three years away in China, I

发帖数: 7521 | 2 How America Can Rise Again
Is America going to hell? After a year of economic calamity that many fear has sent us into irreversible decline, the author finds reassurance in the peculiarly American cycle of crisis and renewal, and in the continuing strength of the forces that have made the country great: our university system, our receptiveness to immigration, our culture of innovation. In most significant ways, the U.S. remains the envy of the world. But here’s the alarming problem: our governin... 阅读全帖 |

get the drill.
"diesel fuel is a lubricant in itself, low RPMs definitely help drivetrain
and engine components last longer, but diesels last longer because of two
main factors....
number one, they are built tough as hell, they use iron blocks and iron
heads. thick iron has a better fatigue life that aluminum or milled steel.
diesels must sustain a very high compression ratio, so therefore they tend
to make those iron s... 阅读全帖 |

作为本系列的第二篇，笔者在这里将要探讨世界上唯一的超级大国---美国的科研情况
和发展趋势。不可否认的是，被称为“新罗马”的美国作为世界上唯一的超级大国，在
绝大多数科研领域都占有绝对优势。目前来看美国科研经费较充足，人民的生活水平也
在发达国家中算不错的。同时美国还采取了较为积极的移民政策。这使得美国有机会吸
引全世界最优秀的人才。但是美国目前的基础科学科研也出现了严重的可持续性发展问
题。对美国科学发展的历史现状和未来进行分析，是对我国的科研规划和发展有相当的
借鉴作用的。
在19世纪末期，美国成为世界上第一大工业国，庞大的工业生产能力催生了巨大的工程
学研究需求，而工程学水平的提高又依赖于基础科学的发展。在强大工业增长的刺激下
，美国的工程学和基础科学研究开始高速扩张。20世纪初，迈克尔逊和莫雷成为第一个

不过还要考虑什么样的房子配什么样的材料，不好overbuild
PS: 羊毛地毯怎么买比较便宜？
and last very long time. I have seen some that is over 30 years and still
look like new. |

发帖数: 1980 | 6 The keyword that CA is different is "migration". California after all is an
attractive place to live.
So in crash, We bottom out when unemployment goes up and migration exits the
state. But in bubble, employment improves and migration of people favors
California over other destinations, when everyone can get a job anywhere.
The rest is supply and demand.
California actually doesn't have significant overbuild in the last bubble (
except maybe cities like stockton, merced), what happened to the de... 阅读全帖 |

expand my target area to include N phoenix like cave creek etc. There are
much more choices there.

N. Scottsdale?
Besides, I think Scottsdale is the one with highest risk for further price drop due to its inventory level, 8 month supply vs. 3 month supply for other towns. It will have a slow and long correction.

发帖数: 3837 | 9 弯曲斜坡上建房绝对是考验婚姻、亲情、毅力的一件事。结构上只有overbuild。
我有个邻居就此被foreclose了，买了一块山坡地，地价便宜，景色很好可以俯瞰整个
山谷，但是倾斜度大了点，92年买跟city planning讨价还价到99年才能起房子，被要
求加固整个山坡，房子都是钢筋的，还没开始打地基就花了20万。等到终于开始建房，
被要求一定要钢筋，结果建筑成本飚升，不到4000尺的房子就起了一个骨架就花完了
100万，最终熬不过foreclose掉。
最可怕的是，这个业主本人是个建筑师，连他都大失预算。 |

而且不便宜啊，都快100万啦。 |

发帖数: 373 | 11 Ardenwood 那里overbuild很严重，房子挨着房子，很紧凑。
94536 还凑合，不过去半岛也不近，多走10多分钟

发帖数: 4396 | 13 you don't need to worry about it. all you can do is looking out for cracks
in the highly stressed parts of the frame, like the chainstay-bottom bracket
area, downtube-headtube weld, etc.
the way they overbuild aluminum frames is they set a target life cycle, more
than vast majority of the riders' needs. say, for example, 5 years @ 10k
miles/yr by a 170lbs rider with a peak force on pedal ~600lbs. safety margin
/redundancy is then added--say, the frame should last over 10 years @
20kmiles/yr by 3 |
