STATEMENT
************************

Natural science is probably the most wonderful thing that one can encounghter, which is absolutely challenging, encouraging and illuminating. My academic interests cover many realms, while emphasizing theoretical physics and pure mathematics, as well as their interfaces. Maths-wise, I'm particularly keen on differential geometry, differential topology and abstract algebra. Physics-wise, cosmology and quantum fields win my principal attention.  Although punctuating the theoretical aspects, I do look highly of experiments. Experiments speak louder, and I think an excellent theorist should also be competent in data analysis and process simulation. Besides rational and technical contents, physics and maths imply a natural philosophy, too, helping us understand the essence of the substantial and spiritual universe. Also, no doubt the progresses in genetic engineering, artificial intelligence and new energy techniques etc. will make great differences to human society.

To our excitement, the contemporary physics is undergoing a profound revolution, which will constitute a major change in our understanding of the nature of space and time, the unified mechanism of fundamental forces, and the essence of the cosmos. However, we should be aware that, people are still far from the deepest truth regarding this world.

This globe has been revolutionarily changed due to the invention and widely adotion of PC&Internet, steppling into a digital age commenced by the heroes like Alan Turing, John von Neumann and Bill Gates. It's expected that, the advancement of mankind will be exponentially boosted, and I sincerely wish peace, freedom and prosperity for mankind, as well as harmony between civilization and Mother Nature in the 21st century and this millennium.

SELF-INTRODUCTION
******************************************

I was born in January 1987. I fulfilled my undergraduate studies and got my BSc degree in June 2010. I am now attending postgraduate studies in MUN and join the MSc&PhD program of Theoretical Physics held by the mathematical relativist Prof Ivan Booth.

READING LIST
***************************************

I would like to recommend some monographs on theoretical physics and mathematics based on my studying and research interest. For details, please go to my blog.

Besides the commercial databases Elsevier ScienceDirect, Springer, IOP, APS, AIP, MathSciNet etc, there're three important eprint archives that one can benifit from:

(A)  arXiv: http://arxiv.org/
If you can't access, try her local mirror sites.

(B)  Hal: the largest multidiciplinary preprint platform in western Europe.
English Version: 
http://hal.archives-ouvertes.fr/index.php?langue=en
French  Version: 
http://hal.archives-ouvertes.fr/

(C)  SciencePaper Online: the largest multidiciplinary and multifunctional preprint platform in East Asian, links most universities, colleges and institutes in China

Chinese Version:  http://www.paper.edu.cn/
English Version:    http://www.paper.edu.cn/en/

The Ministry of Education of PRC (the founder of this database) receives lots of critism on the poor quality of the English version and has to speed up the construction.  The English version now has ugly pages and could only act as preprint database, but it is much more rigorous than arXiv and Hal. Also, please use 'IE' or 'Opera' as internet explorers to explore these websites, not Chrome (mis-editting the pages).

4. Lagrange Analysis for Non-Relativistic Particles in the Rotating Reference Frame

Accepted by Science and Technology of Western China, by the Chinese Academy of Science.

Jesus! This legal routine prevents my paper from an official publishing, since I can't afford the charge.

Accepted by Science and Technology of Western China, by the Chinese Academy of Science. But strangely that in China, all scientific journals(except the Chinese Journal of Physics, Communications of Theoretical Physics(China), by IOP) require the so-called "page charge" for publishing papers, wich generally ranks from ¥600 yuan RMB to ¥1500 yuan RMB. Jesus! This legal routine prevents my paper from an official publishing, since I can't afford the charge.
