想起在丽江的幸福时光

没有什么能够阻挡
你对自由地向往

天马行空的生涯

你的心了无牵挂

穿过幽暗地岁月

也曾感到彷徨

当你低头地瞬间

才发觉脚下的路

心中那自由地世界

如此的清澈高远

盛开着永不凋零
蓝莲花

Independence Day

This is the 6th Independence Day I spent in the States - 2004, 2005, 2006, 2007, 2008, 2009. This year it was a Saturday and we went rafting in a small village called Jim Thorpe. I was trying to think of what I was doing in the other independence days. But my memory is vague. All I can remember is that in the year of 2006, Wanyi, Liping, Kun, Jenny and I went to see the fireworks by the river in Toledo.

It was raining for quite sometime before this holiday weekend. On Saturday morning it was quite cool. The river for rafting is about 2 hours drive from where I live. The rafting didn't start until 12pm when all of us finished our branch and got warm up. It seemed that asian people like rafting the most, among them are Chinese, Korean and indian. We were asked to lift and carry the boat and walk into the river to start to make sure we wouldn't miss the coolest water in the river. It was nice floating on the river, since the speed of the river wasn't fast. It supposed to be a five hour jorney. However, none of us brought any time machine. Most of the time, we were active in paddling, quietly guessing who would be the first to fall and how. Soon the answer was unveilled without surprise, the largest guy on our boat. We were not in the front of the group, however, there were several times we were in good position before the boat was suddenly held by some big rocks. The biggest accident of our group was a boat being pulled out of water for getting a hole. In conclusion, I wasn't fall into the water and this enlarged my safety record of rafting.

On Sunday, I watched several movies and TV drama, among them there was one interesting. She was the queen of Louis XVI, the king who was beheaded after the revolution. So was she. But the movie was well arranged only to expose the happy part of they life.

To Understand the Boltzmann Transport Equation

Here are some internet resources

1. The easiest and vivid explanation of BTE: http://homepage.univie.ac.at/Franz.Vesely/sp_english/sp/node7.html

2. Fundamental textbook: Microscale energy transport By Chang L. Tien, Arunava Majumdar, Frank M. Gerner

3. Explanation of phonon dispersion: http://www.chembio.uoguelph.ca/educmat/chm729/Phonons/intro.htm

Study notes:
Phonon
1)An ensemble of travelling waves having a certain frequency, n, a certain group velocity, Vg , and carrying with it energy equal to hn , where h is the Planck constant.
2)Just as light is a wave motion that is considered as composed of particles called photons, we can think of the normal modes of vibration in a solid as being particle-like. Quantum of lattice vibration is called the phonon.

Wave Vector k -- a vector which points in the direction of propagation of the wave.
Phonon Dispersion -- the relation between phonon frequency(energy) and wave vector

K教授

仙风道骨的原子传热学领域大拿K教授上周来公司传道解惑。看见他,就好像孙悟空当初看到菩提大师,心里喜的只能用抓耳挠腮来表现。世间还是有贤人的!

星期二 lousy

星期二是昨天。早起新闻说最近东部气候异常,总是刮风下雨,有市民甚至质疑今夏到底还有没有像样的夏天天气了。昨天就是一个这样的阴风飕飕,冷雨飘飘的日子。所以我很blue。

大狮说不能理解,“觉得这是心理不健康的表现。症状持续的话,考虑吃药吧。”

道长很理解,道长说“日照对动物的影响是非常大的。比如熊身体内负责冬眠的激素就是和日照直接相关的。以前认为熊冬眠是因为食物减少,饿了就冬眠。但是后来证明不是。有时候秋天收成不好,熊会活活饿死都无法通过提前进入冬眠来节省体能。而有时候收成好,到了冬天仍然有很多事物,熊一样会冬眠。
天气晴朗有利于人类打猎采果子。这时候,我们身体就会为出去打猎采果子做准备,兴奋起来。这个是进化的结果吧。其它动物看他们的生活习惯,“好天气”的标准也会和我们不一样的吧。”

总之在这样一个潮唧唧的天气里,自我调节很重要,下班后我决定去游泳。可是游泳池那里居然在开居民联欢运动会。

有啥好说的呢, C'est la vie!

Addicted


These two days, I have been addicted to a small online-game, "Mushroom Farm Revolution" . The idea is to put the mushroom-like guns to appropriate locations along the path where the targets emerge wave by wave. Once the gun is set, you don't need to trigger it to shoot. It will find its targets as long as they are within its shooting range. You start with the money only enough to buy two guns. You can make money out of killing the enemies. Aside from guns, you can also buy gun accessories to enhance the gun power, which are 5 color precious stones. The idea of the color stones is the same as the Chinese Wu-Xing, which means each color will weaken one kind of enemy but enhance the other. So it is curial to equip the right stone. By making different combination of the stones your gun can have different functions, such as 5% chance of instant death, 3% chance of slow the enemies, 5% chance of more bullets, and etc. So here I am, keep playing it for 2 nights and stuck at level four. And keep playing it in dreams.

One more night passed and still no break through over level4, I decide to search strategy online. The first link came up in google, its title read like this "Mushroom Farm Revolution - Free Strategy Game from AddictingGames". What do I say?

【文摘】 朱棣文 Steven Chu

[Time] May 11, 2009 全球100位最有影响的人物

身为科学家的一大难题,也许是学会如何在言谈中不流露出科学家样来。朱棣文就精于此道-而这点对我们所有人是好的。朱,61岁,美国新任能源部长,曾在1997年因其尖端物理研究(esoteric studies in physics)而获得过诺贝尔奖,而同时他还致力于分子层面上的生物研究。

然而,也许朱最大的影响力还是来自于能源领域。身为倡导美国终止对石油依赖的长期代言人,朱以其能力和魄力受到了总统Barack Obama的青睐。地球气候的未来依赖于我们重新思考如何使用能源,尽管他的两项优点都将同等重要,但是其魄力也许是最令人耳目一新的。

在他办公室的首次访谈中,面对Los Angeles Times,他坦诚如果我们不行动以改变气候,那么到本世纪末内华达Sierra山顶的积雪将融化,届时加州的农业将无法幸存。 对于关注此事的人这是个明摆着的事实,但是这样的事实我们却已经很久没从政府官员口中听到过了。朱棣文的魄力也许将开创一股全新的坦率之风。

周末

脸还是肿着,体积小到一定程度,就不再缩小了,肿过的地方,现在看起来好像擦了碘酒,黄绿黄绿的。一直下雨。花粉过敏又开始了。所以宅在家里,看pps。
跟的美剧都没有更新,发现abc的新剧castle挺好看,男主角是DH里曾和lynett有过险情的厨师,他的嘴部的表情很像bruce willies,女主角是个美丽的干探,专管凶杀案。该剧的chemical很对我胃口。顺便把大奥又看了一遍。日剧和美剧比较像的地方是不嘲笑观众的智商。但是下雨天还是不宜看日剧,简直要闷死人了。
下雨天,牛顿一周都没有机会出门跑步,也很忧郁,所以决定见啥咬啥。但是地上的东西都被我收起来了,选择实在不多。他于是满屋子学么,找各种纸制品过嘴瘾,他的最大乐趣就是“咬得粉粉碎”,拿手好戏是叼面纸,咬得粉粉碎。晚上终于给他逮到机会,趁着傍晚灯还没开很昏暗的时候,叼到了窥却已久的那块栓皮栎隔热垫,等我回过味来的时候,是他又在我脚下撒尿,一看已经是一地碎屑了。被我一把揪住,扭送牢房。可是他咬得还不够碎的能被吸尘器顺利清理,今天晚上回去,我还要修理一下吸尘器。

大肿脸

虽然每次上照都是大脸猫的形象,但是都没有这次来的彻底。周一早上拔完牙,全麻,醒过来没啥事,也不疼。就是有些肿。医生给了个notice,说48小时后会达到最高峰。今天刚好就是这个高峰。前天是圆下巴,昨天变成四方的,今天惊现到三角,非常像没头脑。休息了2天,今天早上我先跑到药房,想买个口罩,遮一遮,没想到猪流感当前,我们这里的药房竟然还一点未雨绸缪的准备也没有。他们寻了半天,找来一盒子一次性口罩,我没买,用不了几天就能好的,买这一盒子好晦气。于是我很不甘心的接受了同事们的慰问和检阅。不让他们笑是不合适的,万一人家内伤了,岂不是我的不是,我也想陪着笑,可是脸都绷紧了,没有活动空间了。
最后,我讨厌吃药。
