Today I gave a talk to my mentor of graduation essay. Prof. Liu is very interested in the method I used in my thesis and she wanted a systematic explanation of the whole process.
Besides, she thinks that my method is creative and wants me writing an article and publishing it in domestic kernel journal. This plan is attractive and exciting. The only problem is that I don't know whether my idea is really so original and valuable.
Well, here is the chance, so just do it.

[Ecology] Summary of ‘Ecology of a Changing Planet’, Chapter 2
This afternoon I spent about 4.5 hours in a coffee shop reading this book. I was very dizzy but knowing that sleep when sitting is not good for your heart and brain so I just tried every effort to keep myself awake.
The title of this chapter is 'Chance, Change and Evolution'. it discusses the lifecycle of a species: evolution, survival, and extinction. Evolution here is forming a new species, when the genetic change is profound enough. The definition of 'species' is that the population is reproductively isolated.
Chance events play important parts in evolution.
Life formed in primitive oceans. The organic molecule's forming from inorganic materials is a small-probability event but it will occur giving enough reaction chances. The early life utilize sulfuret and energy from sun or earth to produce CH_2O.
There has been much more life forms in certain periods than today, for example, Cambrian. Many species extincted in the past. In fact, extinction is part of the history of life on the earth. Human is *not* the most advanced form of life. We are just lucky enough to survive. And we are just a twig of the species bush.
The life of a species may be from 4 million to 22 million years. Every species will extinct, sooner or later. In the past, it's meteroids' impact accelarating this process. Now it's human doing the same job.

2K Pass
先说一下 1K 被拒的经过。
准备的材料有：VAF1 表、学生问卷、照片、毕业证、学位证、成绩单、户口、Cond. Offer、USD $ 30K 多的存款证明（2000年一次存入）、父亲的工作证明、房产证复印件、IELTS 成绩、TOEFL 成绩、清华水平一证书
被拒的理由是工作证明太过简陋，不够正式，而且 30K 多的存款换算成英镑只能勉强够学费和生活费。
曾经考虑过申诉，但自己材料准备确实不充分，而且申诉要送到英国处理，估计等出结果黄花菜都凉了。于是准备 2K。
补充的材料是 USD $ 30K 多和 10K 多（1998年一次存入）的存单各一张，以及存款证明。还有以父亲所在公司总部名义开的工作证明（原来是以地区办事处名义开的）。
递材料那天人很多，我中午才到，好在 rp 不错，排到未预约的第51号，14:15 才叫到我，那天未预约的一共受理了60来个的样子。
昨天晚上查到状态变了，于是今天早起，赶到签证中心。拿到信封后没敢马上拆，怕中介来纠缠。出了东环广场才打开，一下看到护照上 UK Entry Clearance 字样，心中大石终于落地。给了我17个月的签证，到07年1月。
总结：税单和工资单非必须；
VO 对二签没有歧视；
钱的准备要充足一些；
亲属关系公证非必须，但最好有担保信。
**********************************************
签过了以后马上给 n 个人发短信报告好消息。这种如释重负的感觉确实比较爽。虽然之后还有一大堆杂七杂八的事要做，不过总算是把最重要的事搞定了。也祝小 P 签证顺利。

[Ecology] Summary of ‘Ecology of a Changing Planet’, Chapter 1
Things that I already know are omitted.
Ecology is a science concerning how nature worked. Environmentalism is just a concern. The environmentalists' idea may be drawn on scientific data, but also may be based on emotional appeal or on ethical or moral criteria. There are environmental science, too, which studies the influence of human actions on natural processes.
Natural selection is the mechanism that determines which lineage leaves the most descendents. At the same time it is the loss of all members from a population other than those with optimal genotypes. Those lineages with traits best biological programmed will have better chance to leave more descendents. The parents are successful in this therefore new generation too different from the parents may not be so successful. Natural selection, contrast to people's assumption, don't encourage mutant but heredity.
In Further Readings, maybe I can find Grand(2000).
See http://www.prenhall.com/bush for relating online resources.

Vagrant
It was 12:00 at noon. I was in Tsinghua University's tenth mess hall waiting for one of my friends, who needs to share the fee card with me. I feel reluctant. I should have been here half an hour earlier and there will be less people. If I just use my own card, I will just have my lunch alone. Yeah, why not? I can choose the time and place for any of my meals. Suddenly I find out a bit about why I can't be with my ex-girlfriend for a long enough time. I am a vagrant. I want to arrange my time myself. I don't want to wait for someone before I want to do something. Nor do I want anybody telling me "it's time for this" or "it's time for that" against my own decision and habitats. Another people having every meal with me will soon or later make me mad. I have too much of my own business. Don't tell me someone will change this. It will only change when I finally learn to be still one day. Not in the predictable future. I am glad that I didn't run into some people's lives before. They will not be hurt by me and my vagrant character now. Sometimes I do feel alone. But at such times what I need is a spiritual companion more than one who eats with me. I don't like love and girlfriend being brought down to physical level.

History is repeating itself
Today I read an article in a magazine called Nanfang News Weekly. It is a comment on the founder of blogchina.com, Fang Xindong. The article mentioned how Fang decided to start blogchina.
A few Years ago Fang wrote several articles on Micro$oft's monopolization over the OS market. Micro$oft's media department was powerful enough to control many portal websites and they deleted Fang's post at once. Fang was very angry and he began to look for a media that can't be controlled by large firms like MS. Then he found blog and started blogchina.com.
About 3 years later, I also find that my blog entry concerning censorship is deleted on blogchina.com, so I abandoned that blog and started this one. Today when I read this I feel history is tragically repeating itself. blogchina.com now is also a tool of censorship and filtering.

Some unpleasant feeling brought by CAU’s publication
On the roof top we haven't got much to read. Today I picked up a magazine edited by China Agriculture University's mountaineering team. It has a lot of articles. Most are about their May day holiday.
They went to Mount Sigu'niang (the Four Ladies) in Sichuan province and Xiaowutai Mountain in Hebei province. A female team member who went to Sigu'niang described her experience of falling on a snow slope and (I guess) hypothermia. She talked with no sign of fear or regret.
There is also an interview to their most experienced team member, called Asan. Asan was asked if he is afraid about death. But he just said death is nothing special. He even asked: "who should be afraid of death?" Geez, I don't want to climb any mountain with such daredevil. As one who has climbed a few snow mountains he should know there are something to fear.
The principle of CAU, famed Professor Chen Zhangliang is very supportive to the mountaineering team. But I think this has some negative effects to their development. They may get too aggressive. In the magazine they even mentioned that next year they will begin preparing for climbing Mt. Everest. This could be very dangerous for a team established in 2003 and lack experienced climber.
