要镇定，take one step at a time

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.

What is the BTE?

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！
