Earth Quaked

japanEQ

     Earth quaked this morning around six, tore my nice dream, broke the drainpipe at the balcony, yet added a bit breeziness to the humid, hot, and dreary summer. Honestly, I didn't have even a single bit of worry about safety since I knew instinctively that nothing worse was to happen. Were it not the noise caused by the water leaking out of the drainpipe at the balcony, I wouldn't even bother getting up to have a quick check. This was in fact the first time I was aware of an earthquake, and certainly I hope it'll be the last time too.

观上海杂技团表演

In the evening of April 30, 2010, we went to watch an acrobatics performance, titled "Revolution", by the Shanghai Acrobatics Troupe, for the publicity of the Shanghai Expo'10.  An album of selected photos of what I took in the show have been uploaded to my web gallery. Taking my son to this acrobatic performance was meant to be a surprise and an encouragement to him for his being a good boy. Nevertheless, the performance turned out to be an unexpected, fascinating entertainment for my wife and myself too. In fact, not only us but also all the audience, Japanese and Chinese, were greatly amazed; the gigantic tent was filled ...

春寒梦呓

天问

昨夜于梦中得古诗数句,今朝推敲增删,恰凑得成八韵五古一首。 春寒梦呓 - 梦成五古八韵注 春寒万籁轻, 月华漫窗棂。 梦浅乡愁近, 顿怜父母情。 十载决然去, 苍鸟飞不停。 乏力从定远, 报国岂无凭? 封侯尘土没, 格物释儒倾。 书生必有用, 枯坐太玄经。 燕雀迷堂构, 鲲鹏探杳冥。 会当答天问, 斗酒祭屈平。 注:情与倾同诗中其他韵脚古时并不同韵,今应可不必区分。

诗词用典小议

蒹葭

皆谓今人之填词作诗宜多用典,典用则古意盎然,格调高致。余以为不然。非谓典不可用,实须适度为之,若处处寻章摘句,假古人言,则艺文一道何以进步,何以 发展?子云:“《诗》三百,一言以蔽之:思无邪。” 何以思无邪?盖直、真、挚三字而已,岂有他哉? ”蒹葭苍苍,白露为霜。所谓伊人,在水一方……“ 何其直白,真挚也?若言《诗》乃后世诗词之祖,无典可用,则唐人诗作中可谓 “千古绝句” 者,亦多为不用典者。 “花间一壶酒,独酌无相亲。举杯邀明月,对影成三人……” 何典之有? “空山新雨后,天气晚来秋。明月松间照,清泉石上流……” 何其直也? “无边落木萧萧下,不尽长江滚滚来……” 又何典之有欤?仅此一句便可关千古登临之口,几与 “西风残照,汉家陵阙。 “同。“平林漠漠烟如织,寒山一带伤心碧……” 词尝疑为太白所作,非也,实乃宋人托古之计也,然世人信焉。何也? ...

Back from Hongkong

Several days ago I attended a small "Workshop on Quantum Information Science" at the University of HongKong. 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 workshop, whose goal was to stimulate collaborations, I had an exciting discussion with some mathematicians. There, I also ran into a bit difficulty in communicating with pure mathematicians, who had little background in General Relativity. Though mathematicians and physicists have different ways of thinking in general; however, it was actually my problem most of the ...

Measurement of Link Invariants: Introduction

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 or aren't willing to do so, this blog entry and the one follows, which will show up in a day or two, would help you to understand the gist of it. In any case, I quote the abstract of the paper in below for your reference (but don't get dizzy by seeing the jargons therein). The ...

Collaboration Distance

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. Well, it is somewhat shameful that I'm six steps from my own boss; nevertheless, it's fine for now because I just joined his group two months ago. That said, a goal, according to my boss, is to eliminate the distance between us.  Now go back to the collaboration distance itself: how did I get it? Collaboration Distance Calculator is simply a free web tool provided by ams.org. It's been there for quite a while already, how could I ...

沉痛哀悼钱学森

钱学森个人简介

钱学森-中国航天之父、两弹一星元勋今日在京去世,享年98岁!钱老生前,名字家喻户晓,身后,他的名字将被永远铭刻在中华民族的史册上,而他的灵魂,将会永远关注并守护着中国的复兴。在中华民族浴火重生的苦难历程中,有不少人立下了盖世奇功,而钱老是其中最为功勋卓著的一个。作为一个海外学子,钱老一直是我心中的楷模,期待着能像他一样,为祖国为社会做出贡献。我想,应该还有千千万万的海外学人以钱老为学习的榜样,以其成就为毕生追求的目标。 钱老逝去,西风萧瑟。在这样一个深秋的日子,让我向着祖国的方向,三鞠躬!

博客被黑 (Blog hacked),恢复中 (being recovered)......

hacked

繁忙的上半年和悠闲的夏天令我无法关注自己的博客和网站,倏忽到了八月某天,赫然发现网站被某个该死的不知名的黑客给黑掉了,论坛、我和我妻子的博客,以及我的网络相册统统被抹掉,只剩下该黑客留下的一个网址,在“耀武扬威”。我不知道黑掉这样一个物理网站有何意义,更不知道黑掉这样一个没有高度设防的网站能显示什么电脑水平,对于如此没有技术含量的黑客行为,我只能报以无尽的鄙视,当然,也不免问候一下他的家人。 同时我也要检讨一下自己,没有给网站做离线备份,更由于许久没有管理网站,服务器上的旧备份也早被空间提供商删除。这对于计算机科班出身的我来说是不可原谅的。所幸的是,供网站和博客使用的数据库还在,使得恢复网站有了些许希望。发现网站被黑后的那段时间非常匆忙,又是办理签证、购物、又是离愁别绪,根本没有心思想博客的事情。 ...

My Web Album Released

I have built a web album – World of Lives – to share selected photos of all I have taken. Well, it will be tremendously time-consuming to organize and upload all those photos I would like to share; therefore, so far I have only done with the ones of Oxford, England, taken on my way back to London from Nottingham after the conference QG-squared. I will keep increasing the volume of my web album as long as I got some time to kill. A link to the album is also added to the homepage of my website. Hope you will like it! ...
