     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

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.

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。

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

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

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,

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!
