Pretty nice, but the matte black frame with iridium lenses are my favorite.

发帖数: 70028 | 5 近日，中国多地发生奶农“倒牛奶”事件，许多人由此联想到中学教科书中提到的“资本家宁愿将牛奶倒掉也不分给穷人”。事实上，发生在20世纪30年代美国大萧条时期的一系列倒奶事件，可能和教科书描述的、和你想象的都不太一样。
1929年大萧条重创美国农业，具体到奶牛养殖，大萧条头5年，全美最大的产奶州威斯康星州牛奶零售价由4.79美元降到3.48美元，奶农在零售价中收益占比由46%降到30.5%；纽约州情况也类似
和其他繁荣的行业所不同，在1929年大萧条开始之前，美国农业就已经经历了长达10年的由农产品过剩等原因导致的衰退。而1929年开始的大萧条进一步 重创了美国农业，从1929年到1932年，农产品出售价格下降了近50%，农民需要购买的日常消费品价格却只下降了32%左右。
技术进步提高了全美的产奶能力，在1929年，美国共生产了110.52亿美国加仑(US gallons)牛奶，威斯康星州、明尼苏达州、纽约州是美国当时最大的三个产奶州，牛奶产量分别为12亿、8.25亿、8亿美国加仑，它们受大萧条影响最大。
根据美国商务部下属网站census.gov的数据，在1929年，威斯康星州63%的土... 阅读全帖 |

发帖数: 61690 | 12 新浪读书讯 瑞典诺贝尔委员会2011年10月6日下午1点(北京时间10月6日下午7点)宣
布诺贝尔文学奖得主。瑞典诗人托马斯·特朗斯特罗姆(Tomas Transtromer)获2011年
诺贝尔文学奖。
托马斯·特朗斯特罗姆(Tomas Transtromer)，1931年生于瑞典。1954年发表诗集
《17首诗》，轰动诗坛。至今共发表163首诗，除《17首诗》外的作品结集为《途中的
秘密》、《半完成的天空》、《音色和足迹》、《看见黑暗》、《野蛮的广场》、《为
生者和死者》和《悲哀贡多拉》十部诗集。
1990年患脑溢血导致右半身瘫痪后，仍坚持纯诗写作。
他善于从日常生活入手，把有机物和科学结合到诗中，作品多短小、精炼，往往用
意象和隐喻来塑造个人的内心世界，把激烈的情感寄于平静的文字里。
他被誉为当代欧洲诗坛最杰出的象征主义和超现实主义大师。多次获诺贝尔学奖提
名。
1992年诺贝尔文学奖得主沃尔科特曾说：“瑞典文学院应毫不犹豫地把诺贝尔文学
奖颁发给特朗斯特罗姆，尽管他是瑞典人。”
诺贝尔委员会颁奖词：
通过凝炼、透彻的意象，他为我们提供了通向现实的新途径。(Through his... 阅读全帖 |

--- By Fiona Rawsontile, Sept 2015
This interview was inspired by an earlier interview of Dr. Yin I saw on the
Internet, which made me think that we can’t expect someone who normally
writes for entertainment to understand a physicist. To “provoke” a
scientist, we need another scientist. So I volunt... 阅读全帖 |

创教不如改教，模仿一贯道搞五教合一
创立新教，不如高仿现有宗教，还可以塞点私货。
一贯道搞五教合一，是个很不错的思路。五教都是神，都是道，都是天帝/上帝，都是
唯一真神,都是宇宙最大佛，都是自然神。当然现在回教徒进入疯狗模式了，暂时可以
把回教排除。
这样可以随意盗用各派教义，但实践上取那些通俗易懂的部分，行善积德，广种福田之
类的。同样也可以随意盗用各派的宗教仪式。
基础教义容易，下几本电子书综合一下就行。后面传教才困难。开山总坛设在哪里，总
坛设在大城市，才有利传教，但大城市地价又太高。弄一个总坛，从土地到建筑加各种
高仿神器，中小城市也得几十万吧。第一笔启动经费哪里来。
总坛有了，后面外地个个分坛香堂怎么管理？是搞上下级任命? 还是民主选举？

空，除了个别时候remove non condensable gas，根本不用不断泵。
至于GE的膜，哈哈哈哈哈哈。以前在EPC公司工作系统的中试比较过5，6家大公司的。
现在，因为工作关系没法评价GE的膜了。反正GE的东西，你做好准备比市场fair value
高个几倍再说吧。 |

发帖数: 6361 | 47 10月出版的顶级学术期刊Science刊登中国科大潘建伟长文，这是潘建伟课题组第一篇
Science。
Science和Nature都是顶级学术期刊，水平类似，但潘建伟教授似偏爱Nature，在
Nature主刊发表论文甚多。Nature杂志出现的量子信息论文更多。凝聚态物理方面潘建
伟发表了关于波色爱因斯坦凝聚的长文，潘建伟发了十来篇Nature主刊后终于在
Science上也灌水了，而且是以长文（RESEARCH ARTICLES）的形式发表。
潘建伟组的论文题为《Realization of two-dimensional spin-orbit coupling for
Bose-Einstein condensates》。合作者包括北京大学国际量子材料中心（Xiong-Jun
Liu）等人。有趣的是北京大学该中心负责人是谢心澄教授（中国科大774校友）。潘建
伟本期Science成果主题是量子模拟，或说是超冷原子，并非最为关注的量子通信研究
。该论文已经出现在论文预印本网站，论文点击这里 这是论文预打印版https://arxiv

List of scientists opposing the mainstream scientific assessment of global
warming
Scientists questioning the accuracy of IPCC climate projections
These scientists have said that it is not possible to project global climate
accurately enough to justify the ranges projected for temperature and sea-
level rise over the next century. They may not conclude specifically that
the current IPCC projections are either too high or too low, but that the
projections are likely to be inaccurate due to inade... 阅读全帖 |

，占电厂用水量的比例相当低。废蒸气引入热交换器，就可以用海水来把废蒸气冷却成
淡水，然後淡水再次循环引入锅炉。
我们一般说的冷却水，指得是Condenser用来做热交换移除热量的水，而不是蒸气锅炉
用来产生蒸气的水。 |
