A compromise between earth-expansion and earth-contraction is the "theory of
thermal cycles" by Irish physicist John Joly. He assumed that heat flow
from radioactive decay inside the Earth surpasses the cooling of the Earth's
exterior. Together with British geologist Arthur Holmes, Joly proposed a
hypothesis in which the Earth loses its heat by cyclic periods of expansion.
In their hypothesis, expansion led to cracks and joints in the Earth's
interior, that could fill with magma. This was fol... 阅读全帖

近日一则美军新闻透露了美军F-22战机的真实战斗力:“第94战斗机中队在6个月叙利
亚部署期间,全中队完成超过590架次飞行任务,飞行时间超过4600小时,投掷4250磅
炸弹,监视和驱离了587架次敌对方的飞机。”
一、那些惊人数字可能不是23架机,而是6架机完成的!
这些数字很牛,4600小时/590架次=每个架次要飞7.8小时;180驱离587架次俄军和叙军
飞机,平均每天要干3次多;就是每天架次似乎少一点590架次/180天=3.27架次/天,对

为什么是6架?而不是20多架?默虹推断的理由有三:

XLNX属于在一个小市场,大鳄们不愿碰,小公司也不那么好做。FPGA领域只要有大公司

来自主题: Arizona版 - Climbing @ Queen Creek today.
昨天晚上从Climbmax回到家,接到朋友电话今天去攀岩。结果害的我大半夜的在家翻箱
倒柜找gear,还牺牲了今天早上的懒觉。不过还是值得的啦,除了风比较大(有两次我
快爬到顶的时候感觉都快被风吹飞了),其他都不错。我们一行5个人,我和另一个女
孩一组,3个男生一组。我因为昨天刚爬过gym,只爬了四条,两个5.9,一个5.10a,
一个5.10b。其他人都爬了6条,除了一条5.7,其他不是5.9就是5.10。rock那个锋利
哈,割得大家直骂娘。我的几个手指都割破了,而且很多地方都很pumpy(我这个周末
够我明后两天受的)。Queen Creek 有很多好的攀岩的地方,除了我今天去的,比较
popular的有The Pond和Atlantis. 等大家多爬几次gym,有机会组织大家去哈 :)
这个是今天去的地方的链接,叫做Magma Gardens.

Ken Hudnut 说得没错。估计是写上面文章的老记弄混了。重复一下
1。南加圣安德烈斯断层很可能在今后30年内发生大震 (~30-40%)。最大震级为8级左右
。see http://pubs.usgs.gov/of/2007/1437/
or http://pubs.usgs.gov/of/2007/1437/of2007-1437_summary.pdf
2。美国西北海岸(off the coast of Washington and Oregon) 可能会发生9级左右强
震 (尚未有几率估计,上次发生在1700年。平均发生间隔为300-500年)。加州也会
受创,主要是高层建筑,和海啸。
3。这个“加州的火山喷发岩浆”实际上是 Mud Volcano (泥火山), 不是一般喷发岩浆
(magma)的火山。泥火山可能被地震诱发。但泥火山不是总是在地震前发生。

Dozens of climbers caught in middle of deadly volcanic eruption
At least five mountain climbers were killed and more 15 others were injured
or missing when Mayon Volcano in Albay, Philippines, spewed ash and volcanic
rocks Tuesday, a National Disaster Risk Reduction and Management Council (
NDRRMC) official said.
The explosion caught the mountaineers by surprise as there were no signs of
eruption before they climbed the picturesque mountain. Local authorities do
not usually allow climbers when a... 阅读全帖

来自主题: SanFrancisco版 - 有做analog设计的吗?有些问题请教。
版上有做analog设计的吗?请教一下现在业内有无好的analog migration或reuse的工具
,比如Magma 的titan,可以帮助用户利用已有的设计移植到不同的tech node工艺,或
者另外foundry的工艺。
