Personal History
Posted by mathwww on December 24, 2006
It is a long and circumscribed way for me to the position of a Ph. D. student in mathematics, and my motivation to start actually due to an IMO Medal prize, Qihui Zhu.
As a student in middle school, I was noticed by my teachers for my talents in mathematics, therefore got some training in math competition till high school. Once upon a time, I was introduced to Qihui Zhu, the son of a friend of my father. Qihui was a very talented student in the best high school in our city that kept acing all regular exams in high school and won a Silver Medal and a Gold Medal in 2 IMO competitions, respectively. It was an unexpectedly impressive meeting that he first showed me how cool one could be when solving a math problem. I still remember how shocked I was when he quickly solved several problems that annoyed me for weeks in quite a decent and elegant way. Besides his fast response, the viewpoint and methods he adopted in solving problems showed me how interesting mathematics can be, I mean, other than just mean value inequality. From then on, I decided to be a problem solver as cool as him, and devoted myself to math competition.
Unfortunately, I did not have the chance to see Qihui after that. On the other hand, my high school actually focuses on the National Matriculation Exams, thus teachers don’t pay serious attention to mathematics beyond high school. I was frustrated after several times my teachers did not pay any attention to my questions–even the multiplication of matrices, and decided to do everything myself. My load on regular courses were not reduced at all, so I stayed up late to read mathematics after dealing with stacks of homework. At that time, I had little time to spend on entertainment. The most frustrating thing was, which I can never forget, that I was teased by some of my classmates, who kept telling me mathematics is nonsense and asserted that I could never succeed in math competition like judges. Also, my parents told me not to try on something impossible and that I should focus on my study in regular courses. And I did not make it, really, even after 3/4-year overnight self-study.
As I got out of the pain of this failure, I set up a new goal of entering School of Mathematics, Peking University, where many of the IMO, CMO prizers go for their further study in mathematics. I desired for a group of friends who like talking about mathematics with me, after immersed for years in a class in which everyone thinks math was useless and boring. But another joke fell onto me. Because of the low scores in biology, geography and politics in the National Matriculation Exams, I was finally enrolled by Peking University as a student in Chinese Literature.
At that time, I almost surrendered to settle on literature because of the non-stop failure chasing mathematics for years. Mathematics is beautiful, and mathematicians are cool, but I can never be one all my life, I told myself. However, the mathematics courses I audited in math department gave me a fresh touch in the deepest bottom of my desire to be a mathematician. I have tried by myself to divide the area between a parabola and axis into small pieces, and found the dimension of special areas like that in high school, but I was surprised to find that all these can be done in such a simple way of integration; and more mathematical analysis, especially some interesting problems applying Taylor expansions and mean value theorems enchanted me a lot.
In addition, when I was auditing courses in Math Department, I met Jian Wang, a smart student won a silver medal in CMO and eventually my best friend in undergraduate years. Our common interests, or rather, craziness about mathematics quickly familiarized us. We sometimes stayed up until 2 or 3 o’clock discussing problems or tales about mathematicians. Besides him, I got to know quite a few students in Math Department who shared the same goal about our future—to be a mathematician. Among them, I felt the care for each other on the way of learning mathematics I have been longing for years.
My strong will to learn mathematics and encouragement from my friends finally made me reach the decision of switching my major. By self-study, I passed an exam consisting of mathematical analysis and linear algebra and successfully realized my dream of being a student in mathematics. After I joined Math Department, we gradually formed a study group and held a lot of student seminars varying from commutative algebra, algebraic geometry to characteristic classes. Everyone cared about true mathematics and communicate their ideas in the language of mathematics—even during lunch, my friend might shout out: You are definitely wrong! Commutative rings out of Atiyah’s text can have no identity! I love this atmosphere, and I love living and learning with people who talk about mathematics or tales of mathematicians during meals so that I won’t feel lonely. Now many of these friends of mine have gone to different top universities like Berkeley, Columbia, MIT, Stanford to continue their way to a mathematician, but we still keep in touch frequently to discuss what is new to us. Mathematics keeps us soulmates, and I really wish I can join a group like that again.
In this essay, I am asked to show how my personal background informs my decision to pursue a graduate degree. But my reason is quite simple, that is, I want mathematics to be my career all my life, and I want to do this among the most enthusiastic group in the world. With clear awareness that to be a mathematician requires much of my time and efforts, I still wish I could do this with my heart and soul, because I have struggled across so many barriers in my way, and because, basically, I love mathematics.
May I stop here with:
I shall defend the true science in a manly way, extend and embellish it, not for gain’s sake nor a vain shine of glory, in order that the light of God’s truth, shine bright and expand.

教会
Posted by mathwww on December 18, 2006
她很喜欢和别人玩,我猜就和你小时候一样,拿着两根那种“J”形的candy 送给我。我拿了一根,勾住她手上的另一根,就带着她走。小姑娘第一次这样耍,很开心的样子,紧紧地抓住手上的candy 和我一起走,脸上笑开了花,但是我却差点在大家面前哭了出来。这时候一个黑人小男孩,也是差不多大,在爸爸的陪同下来跟小女孩打招呼。小男孩扑哧扑哧地跑过来,就去抓小女孩的头,还连抓了两下,他爸爸连忙拿开他。这时候,我看见的是小女孩从未有过的眼神。她呆呆地看着那个因为伤害她而被带走黑人小孩,看了很久,脸上不知道是愤怒,仇恨,还是惊愕,伤心。此时我的眼泪已经无法抑止地掉在地上。
也许小男孩也是发自内心喜欢这个小女孩的(不是说那种哦),也并不想伤害这个女孩,但是他的懵懂给女孩留下的,只有伤害。但是我也知道,当他们都长大的时候,小男孩会学会喜欢就是珍惜的道理,而小女孩也会找到珍惜自己的人,也不会再记恨小男孩。尽管这不再是他们之间的事,童年的邂逅,只是成熟的过程。也许我母亲说得对,我现在根本没有资格去给女孩子什么承诺。等到我有能力去担起一个女孩的期望的时候,也许我已经忘记了很多很多。

耶和华闻那馨香之气,就心里说,我不再因人的缘故咒诅地(人从小时心里怀着恶念),也不再按着我才行的,灭各种的活物了。

Tattenai’s Letter to Darius
Posted by mathwww on December 7, 2006
- The report they sent him read as follows: To King Darius: Cordial greetings.
- The king should know that we went to the district of Judah, to the temple of the great God. The people are building it with large stones and placing the timbers in the walls. The work is being carried on with diligence and is making rapid progress under their direction.
- We questioned the elders and asked them, "Who authorized you to rebuild this temple and restore this structure?"
- We also asked them their names, so that we could write down the names of their leaders for your information.
