4월 17일 第一天开车今天第一天上车，在教练的怂恿下一直挂到了四档，一脚油门，那个爽啊，呵呵。下决心了，一定要在美国早点买辆好车到处开开，好像有1977年的n手保时捷只要500美元的，不过只能推着走，嘿嘿！ （未全，待续） 4월 14일 一年没有更新了，在过去的一年中，发生了好多的事情。Rutgers, New Brunswick, New Jersey, 一所乡村大学，一个离New York City 40 英里的世外桃源，一个老爷爷，美国最好的古地磁学家，这就是我将要去到的地方。经历了北大的春夏秋冬风花雪月，自己已经不是高中毕业时那个懵懂的毛头小子，太多的悲欢离合与成功失败在我的身上发生，发展，最终却都走向灭亡。那些没有杀死我的，都使我变得更加强大，感觉自己现在的人生态度非常的平静，可是内心的波涛总想冲破外表的波澜不惊。这个学期一直忙于课业与实验之间，回旋的进度，就像风车总是转个不停，忙碌中的偷闲，到春天的郊外去吸纳亲新的空气，心灵也获得了喧嚣的城市里没有的那份特殊的宁静。期待着美国乡村田园的那种意境，林荫的小道，秋日的落叶树，独自漫步在河边思考着稀奇古怪的问题，也许牺牲的是孤独，收获的是天天向上的自我。
以后要把这个blog利用起来，呵呵，欢迎大家有空来踩踩：） 3월 28일 Reflection: ReportOkay, I got it. And I am just preparing a report for our classmates in the coming session .
Hoping it won't be too boring :) Reflection: Task 5Task 5:
(1) Reference Manager
I finally downloaded Reference Manager, a cracked version from Maze. I tried to use the software and found it was realy convenient to orgnize my massive references. I have already created my own database of different sorts of references, books and other relative materials. By keeping adding the new ones into it, I think soon it will grow to a micro-library which will help me a lot on my future research.
(2) 5 minutes free writing
One day Alibaba was wandering on his way to the capital to the Ababila Kingdom. Suddenly, A big mouse jumped in front of him, shouting "I am hungry. Food comes as you do!" Than, it reached out its mouth and nose towards Alibaba preparing to taste the sweet human flesh. And by no reason, the mouse was freezed and died while Alibaba survived.

小鱼儿的世界小鱼儿的世界
生活是水
我是鱼 鱼要喝水 也在水中游 我要生活 也在生活里 清清的水流
是我的风 飘飘的水草 我们的云 水里的世界
天外的天 划破水面 就到太空 浮萍的缠绵
蚌珠的鲜艳 别让那河边的诗 夺去他们的时间 By Huapei Bernard Wang, 11:00, Mar. 27, 2006, at seismology class 3월 26일 Reflection: Task 4 - latest UpdatedTask 4
(1)
I have chosen 3 relative papers discussing the right now great mantle plume debate published on Chinses Science Bulletin 2005 Vol. 50 No. 15.
They are:
1.
Niu Yaoling, On the great plume debate, Chinese Science Bulletin, (2005), 50, 1537-1540
2.
Davies Geoffrey F., A case for mantle plumes, Chinese Science Bulletin, (2005), 50, 1541-1554
3.
Foulger Gillian R., Mantle plumes: Why the current skepticism?, Chinese Science Bulletin, (2005), 50, 1545-1560
My notes:
1. the origin of oceanic plates at ocean ridges, the movement and growth of these plates, and their ultimate consumption back into the Earth's deep interior
2. cool the earth's interior and represent another model of Earth's thermal convection
3. Eath's cooling or whether their existence is purely required for convenience by scientific interpretations
4. Don Anderson, a NIU prof. who disagree with the plume theory
5. plume number: big ~20; resently estimation all of ~5200
6. no unified theory yet exists to explain within-plate volcanism
7. compositional plumes v.s. thermal plumes
8. strictly speaking, there is no direct evidence for or afainst whole-mantle versus layered mantle convection
9. penetration of the oceanic lithosphere across the 660-D into the lower mantle in many subduction zones as reflected by the seismic tomography
10. there is no direct evidence for "free" mass exchange betweenthe upper and lower mantle
11. The "Mantle Plume Debate" is currently rather heated. This debate is perhaps one of the greatest in teh history of solid Earth Sciences.
(2)
My Questions and Problems:
1. How to prove the plume theory?
2. How to get the data and database that I need?
3. Where can I find the references?
4. How to do the calculation?
5. How to make my work more convincing?
6. How to report my work with proper words?
7. Who can be the best expert in this fied that I can consult?
My Solutions:
1. Elsviewn, AGU, Blackwell, reference databases
2. American NGDC (National Geophysical Data Center) priovides the bathymetry, gravity, oceanic age and other sorts of databases that I can download for my analysis
3. Prof. Rixiang Zhu, member of Chinese Academy of Science, a paleomagnetist
Prof. W. Jason Morgan, member of American National Academy of Science, the best geophysist in the world, who first gave the concept of mantle plume
Prof. Y. John Chen, gravity and oceanic sciences
Prof. Keke Zhang, Geodynamo and Earth's interior process
Prof. Jian Lin, oceanic science
4. statistical approaches to analyze data
(3)
The conversation with Prof. Zhang is in Reflection: Task 3.
Finally, I chose my subject to be the correlation between hotspot activity and geomagnetic paleointensity which would directly prove the existence of the CMB originated thermal mantle plumes.
The detials wil be shown in Reflection: Task 5 (upstairs).
