It was a very nice experience. In fact, that was my second time giving a presentation in my home country. The workshop ended up with being fruitful. In particular, in the so-called brainstorming session of the [...]]]> http://www.wanyidun.com/blog_r2u/2010/01/back-from-hongkong/feed/ 2 Measurement of Link Invariants: Introduction http://www.wanyidun.com/blog_r2u/2009/12/measurement-link-invariants-1/ http://www.wanyidun.com/blog_r2u/2009/12/measurement-link-invariants-1/#comments Fri, 25 Dec 2009 04:52:31 +0000 admin http://www.wanyidun.com/blog_r2u/?p=567 Can the link invariants of a link or a knot be measured experimentally? The answer is Yes! This has been done recently by a group of scientists, including Louis Kauffman, and is reported in this paper.  You may go ahead to read the paper directly, which is very comprehensible; however, supposing you don't [...]]]> http://www.wanyidun.com/blog_r2u/2009/12/measurement-link-invariants-1/feed/ 0 Collaboration Distance http://www.wanyidun.com/blog_r2u/2009/12/collaboration-distance/ http://www.wanyidun.com/blog_r2u/2009/12/collaboration-distance/#comments Thu, 10 Dec 2009 12:21:30 +0000 admin http://www.wanyidun.com/blog_r2u/?p=432 Several days ago, my boss showed me the following picture that illustrates the collaboration distance between us.

Clearly, this collaboration distance is the number of coauthors connecting me and my boss.

LHC：我要气死你 作词：Vic FENG 作曲：小柯

投资花掉八十亿，管道埋在地底 数量级十四ＴＥＶ一圈儿二七公里 千呼万唤始出来，日耗无数Money 千万loser来到这里，实验变成博弈 希望越大失望越大，千万别希冀 物理学家在一起，我要气死你

我的beam常打开，质子开始撞击 无数反应同时发生，算也要算死你 我的仪器常损坏啊，天天要修理 每日里故障连连，总是出问题

我要气死你！找不到黑格斯！ 标量场的想法根本就没戏！ 我要气死你！黑格斯终于被抛弃！ 技术色它发挥威力！！！

万人一起做实验，妄想看到SUSY 能级太低流量太少，就是找不到你 万人分析没有结果，电脑也死机 噪声干扰太大了，通俗的道理

我要气死你！就是没有SUSY！ 万亿paper全都变成了垃圾！ 我要气死你！唯象专家痛哭流涕！ 卅年努力付之一炬！！！

我要气死你！找不到Extra D！ 尼玛丽莎全都一边待着去！ 我要气死你！更加没有非粒子！ Georgi也要靠边去！！！

我要气死你！都没达到预期！ 再等五十年去建个ILC！ 我要气死你！理论还有很长距离！ 把疑难留到下世纪！！！

我要气死你啊！！！！！！哈哈哈哈哈哈！！！！！！

一天到晚没结果，全都转行耕地 物理学家越来越少，世界充满狐疑 不爱物理千万别学，真的愁死你 生不如死还自恋，精神有问题

我要气死你！找不到黑格斯！ 标量场的想法根本就没戏！ 我要气死你！黑格斯终于被抛弃！ 技术色它发挥威力！！！

我的beam常打开，撞出黑洞吸你 一切全都化为乌有，宇宙归于沉寂 百亿年后又是一轮，再来搞物理 模型再次遇困难，建造LHC

我要气死你！就是没有SUSY！ 万亿paper全都变成了垃圾！ 我要气死你！唯象专家痛哭流涕！ 卅年努力付之一炬！！！

我要气死你！找不到Extra D！ 尼玛丽莎全都一边待着去！ 我要气死你！更加没有非粒子！ Georgi也要靠边去！！！
