通向英国热核武器之路：起步与摸索阶段
总体规划、决策与组织变动：
1954年4月13日：
由理论物理部主导，奥尔德玛斯顿内部成立“天体物理学委员会（Astrophysics
Committee）”，开始对氢弹问题进行系统地探讨：以专家交换意见为主。
1954年7月27日：
英国内阁决定全面展开氢弹研制工作。
1954年11月-1955年1月：
总参谋部同意，“A型热核炸弹”（大型助爆裂变弹，百万吨级别）、“B型热核炸弹”
（真正的氢弹）中，B型才是最终开发目标；威廉彭尼（William Penney，AWRE所长，
1950-1959）承认现阶段应重点开发“A型热核炸弹”。
1955年3月：
天体物理学委员会讨论“A型热核炸弹”设计，确定其代号为“绿竹（Green bamboo）
”，无法确定其设计是否可行，但争取在1957年进行核试验；“B型热核炸弹”——代
号为“绿花岗岩（Green Granite）”——的研发优先性确定为低。

Inside President Trump’s otherwise “standard Trump stump speech” at CPAC
was nestled what might be a most intriguing observation:
Global cooperation, dealing with other countries, getting along with other
countries is good, it’s very important. But there is no such thing as a
global anthem, a global currency or a global flag. This is the United States
of America that I’m representing.
There's a keen insight in there that could, just maybe, transform our lives,

发帖数: 9698 | 11 美国国旗由中国制造 美媒痛心疾首大呼伤自尊
2012年06月13日 21:56 来源：侨报网 作者：庞克
【侨报网编译庞克6月13日报道】毫无疑问，中国制造的产品为世界做出了巨大贡献。
中国产品物美价廉，全世界也都乐于到中国采购。就连象征一国标志的国旗，中国也“
分担”制造了一部分。但美国媒体对此却痛心疾首，慨叹美国的国旗制造业“堕落”。
Statesman.com刊文称，对于中国制造，美国人抱着比较包容的心，因为世界上很多产
品都出自中国，廉价物美的产品流向世界无可厚非。但唐人街的产品可以由中国制造，
如果连美国国旗也要中国制造，这就有点让美国人接受不了了。
周四（6月14日）是美国国旗纪念日，根据美国人口调查局外贸部门（U.S. Census
Bureau' Foreign Trade Division）的数据，2011年美国从国外进口了价值360万美元
的美国国旗。调查称，其中的大部分——约330万美元产品来自中国。
文章说，就像美国篮球应该理所当然赢得奥运会金牌一样，美国国旗也应该由美国制造
。所以即使省不了多少钱，美国也应该避免从中国或者美国以外的其他国家购买国... 阅读全帖 |

发帖数: 70 | 13 本来打算和朋友一起去landing的，一来他们可能还要等一两个礼拜才能收到护照，
我有点着急，二来我总觉得大雪天的自己开1400多公里很不安全，所以决定干脆
自己做Greyhound得了。幸亏有偶officemate machinecat同学的指点，整个过程
非常顺利。
昨天晚上12点半的夜车，早上6点半到calgary，一路上都在放christmas music，
听得昏昏沉沉的。下车买了份早点正赶上7点的车去border。大部分人都在
lethbridge下了，算上我只有四个人继续往南，而且那三个是去美国的。那三个
人里一对印度夫妇要去LA，厚厚的一打联程车票，分特。一路上继续睡觉，偶尔
醒来听到司机津津有味的说各种边境轶事。中午11点半到coutts，车直接停在
美国这边的office，上来一个查证件的，跟他说我要landing，他很客气地把我
请下车，复印了我的护照，要了我的地址然后给了我一张纸上写：

个对我来说很新鲜，就是建筑系老师说art和architecture无法共存；她也认同这点，
但她又努力同时在做这两样；又能很明确地区分art和architecture这两种不同的设计。

发帖数: 22013 | 16 恭喜你，成为了继liangzhi之后的新造谣大王。
请你把几十支枪武装侵入APA会场的新闻贴出来。
有点常识就知道，
携枪闯入别人会场，是极其严重的犯罪，
立马就会被警察团团围住，打成筛子，
还想着威胁别人呢？威胁得了吗？自己的命都不保吧。
这个造谣大王，估计是把和平示威故意歪曲成了武装威胁。
这个造谣大王，从极端反同的网站上copy了一段文字，还故意曲解成“武装”
结果从那段文字里面，搜索一下所谓的“武装头子”的人名：Frank Kameny，
发现这个人不但从来没有犯罪，而且还获得过很多荣誉。

The sweet pretty things are in bed now, of course
The city fathers, they're trying to endorse
The reincarnation of Paul Revere's horse
But the town has no need to be nervous
The ghost of Belle Starr, she hands down her wits
To Jezebel the nun, she violently knits
A bald wig for Jack the Ripper, who sits
At the head of the Chamber of Commerce
Mama's in the factory, she ain't got no shoes
Daddy's in the alley, he's lookin' for food
