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。 书生百无用, 枯坐老一经。 乏力从定远, 报国岂无凭? 封侯尘土没, 格物释儒倾。 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 phở­tos of all I have taken. Well, it will be tremen­dously time-consuming to orga­nize and upload all those phở­tos 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! …
