oral part of a qualifying test
The oral part of a qualifying test is an especially grilling process to
graduate students because they have to think on their feet. However
clever you are, it is not always easy to come up an answer quickly,
clearly, and persuasively, when the professors are staring at you
and tapping their fingers impatiently.
The process could be traumatic to students with less self-confidence.
To prepare students for the test, I usually give them two advices.
One is to practice on explaining a difficult concept to their 70
years old grandma, and the other is 'It is all right to say you
don't know.'
Many people can memorize and cite definitions, equations, and facts
without any difficulty. But when you ask them what does that mean
exactly, they could offer nothing but to recite the definitions
again. The 'acid test' to see if someone really understands an issue
is to ask him to explain the concept to a layperson such as the
grandma. It is only when we really understand an issue that we can
explain it in plain and understandable language.
Many students stumbled on the simple quest. They threw jargons,
complex equations everywhere to disguise their lack of deep
understanding on the subject matter. They forgot the professors can
easily see through all these tricks.
But human nature dislikes failure and 'do nothing'. We feel so
shameful to acknowledge that we don't know the answer. So even
though every student was given the two advices before the test,
during the test, when the student found that he was in big trouble,
he always struggled to salvage his answer by throwing out more
smoke bombs based on some lame reasoning. The tension would then
be building up in the room, everyone was getting uncomfortable,
until finally the student burst out, 'I think I don't know the
answer.' The professors would usually respond, 'Finally! It's
about time. Now, let's see how do you think you can find out
the answer.'
Like many things in the life, timing is everything. It is very
important to acknowledge one's limitations at a right time.
Admitting one's ignorance too early shows that one is not taking
his job seriously, but doing this too late or totally denying
one's own ignorance is even worse because it shows that either
one is a liar or a fool. Ignorance is unfortunate, but unaware
of one's ignorance can endanger oneself as well as others.
Most of the people cannot do this properly. They feel compelled
to show others that they know everything, even though the cold
reality says that nobody can know everything. In one speech,
Richard Feynman talked about the importance of acknowledging
one's own ignorance. He said, it is the "not knowing" that makes
science progress. If we just think that we have known everything,
not only that is not true, but more importantly, it will only
drag our quest to uncover the truth.
That being said, it is very difficult to admit that there is
something you don't know. The student would rather juggle 10
things in the air while riding on a monocycle than to admit their
shortcoming. Everywhere we see examples like this. Not single
politician will admit that there is something he just doesn't
know. So we see politicians offer and insist their 'expertise'
on every issue. They have a solution for every problem. And
even stranger is that many people believe whatever they heard
from the so-called 'expert' opinion of the politicians. Feynman
said an honest and self-conscious candidate, when asked about
some issues unknown to him, should reply, for example, "I don't
know how to solve the problem about our ailing agriculture. But
if I were elected, I would summon all the top experts in this
area and have them come up a best solution to the problem."
It is very unfortunate that none of our politicians are capable
of these two simple things - to explain truth in understandable
and unbiased way, and to say 'I don't know' when necessary. But
even more unfortunate is that we let them get away with that. We
listen to their biased and overly simplified version of so-called
'truth', and we swallow every solution they throw to us. By not
challenging them, we are in fact encouraging them to become a bunch
of liars, reductionists, morons, or three-in-one.
Everything in this world is complex. Nothing is ever as simple as
any of the politicians might claim. We all prefer a simple solution.
50 brands of cereals only confuse us instead of making us happier,
and that's why politicians are feeding us with simple solutions.
But this desire for simple solution is precisely the reason that
Hitler killed millions of Jews, Pol Pot killed millions of
Cambodians, Serbs and Croats got to each other's throat, and
brothers turned against each other. Many politicians also found
out that the easiest way to elicit support for their simple
solutions was to paint the face of evil for their constituencies.
Serving as a motivator, hatred is as good as love. For some people
it is also much more comfortable to hate others than admitting
one's own fault and insufficiency.
So Jews is the face of evil to most Germans during WWII, as are
the Cham, Chinese, Khmer in Cambodian under Pol Pot regime, Serbs
and Croats to each other, and the South during the US civil war.
Our politicians are doing the same thing. Everyday, they preach
to us about what the face of evil looks like. That is a face of a
particular group of people who looked differently from us, behave
differently, talk differently, think differently, or who once
were or have been involuntarily put in a situation they cannot
really be responsible for. Relentlessly, we are taught to hate.
We are taught to identify the face of evil, and to hate people
with this face. How sad is this. When we should have hated the
foolishness, injustice, and prejudice, we chose to hate people.
But don't forget the table may turn. One day we might find us
on the other side, and people hate us and want to kill us for
no reason other than that their leaders tell them it is the
simple solution to a simple problem. Nothing involving more than
one person in this world could be that simple. Beware of the
self-proclaimed prophet who preaches you about a simple solution.
So when the test comes, be prepared. Ask yourself if you really
understand what is the issue at stake, and listen to the small
voice of your inner self when it says "maybe I just don't know."
Saying 'I don't know' is not a passive relinguish of our
obligation or right. It is an honest acknowlegement of our limitations.
Only by understanding our limitations can we move forward and
try to find another way out the chaos.

Description:
We are developing algorithms for solving Dirichlet problems in bounded domains in n-space. The approach is probabilistic, which has the advantage that generalizations to high dimensions are in principle quite simple in concept. What is involved is to simulate stochastic differential equations in n dimensions and compute the partial differential equation solution using variants of the Feynman-Kac formula. Potential terms are also computed as numerical solutions to differential equations. Two difficulties are evident in this approach to the Dirichlet problem: finding the boundary in a reasonable number of steps, and determining accurately the process value and its exit time. A two layer algorithm is currently being used - a boundary finding layer, and an exit layer whose width is smaller than the weak order of approximation to the stochastic differential equation. Upon entering the boundary finding layer, a step size is chosen to prevent excursions. This means that the bounded approximation to the Brownian increment will keep the process within the domain or reach the boundary. Two approaches have been tested. A walk on spheres method requires modification of the stochastic calculus to confine the random walks to n-spherical surfaces. Our current favorite approach is more amenable to Runge-Kutta methods and is called walk on cubes . Using walk on cubes, the increment of each component of the Brownian movement is a three choice random variable. The step size is determined by the limitation that the process can at most reach the boundary of the domain.
Our results so far show the following features. First, the number of steps needed to find the boundary are O(1/h), where h is the starting step-size. Next, statistical errors due to a finite sample size N are the canonical O(N-1/2 ), independent of the dimension n of the space. In fact, it seems that the coefficient of N-1/2 seems to actually decrease with n. The number of steps required to find the boundary appears to be less sensitive to the initial step size as the dimension increases. All of these results are quite encouraging. Tests on Poisson problems with Dirichlet boundary conditions in hyperspherical domains have been run on problems as large as n=128, and have been carefully studied for n <= 64. Problems with hypercubic domains are currently under way. The algorithms are easy to implement, grid-free, and ideally suited for cluster architectures as they are embarrasingly parallel. Each sample path is completely independent of every other path, so any ordering of subsample sizes can be run on independent processors essentially without communication. Only the partial differential equation solution requires communication when all the paths have exited in O(1/h) steps.
In the following, results are shown for (1/2) Laplace(u) + 1 = 0 in various dimensions in a hyperspherical domain. All simulations were run on the Beowulf cluster Asgard.
Absolute error |u(0)-uN(0)| versus initial stepsize h. The boundary value is 0 on the hypersphere. The sample size is N=104
in the following dimensions: n=1 (circle), 2 (asterix), 4 (diamond), 8 (cross), 16 (triangle), 32 (+),64 (inverted triangle).
Early results are available in a Research Report No. 2002-01, Feb. 2002.

雨天驾驶车辆的技巧 zz
雨天驾驶车辆的技巧
浙江日报 (2004-01-08)
时令进入了多雨雪的天气。作为新手,雨天行车需加倍留神。利用适当档段、适当速度行车,要注意与前车保持更大距离,绝对不可超越前车,这是一个负责任的驾驶员应有的态度。
有经验的驾驶员,对雨天驾驶自有方法,除小心驾驶之外,需要打开雨刷器。如果前档玻璃有霜气,则需开冷气,并将冷气吹向前档玻璃。如后玻璃有霜气,则要打开热风,倘无热风的话,可用半干湿之布擦净,以免看不清后来的车辆。双手平衡方向盘,以防止车辆滑胎,用低档行驶,转弯前应拖档,刹车时不可过度用脚踏下,以防锁死轮胎,而令车辆滑行。如要停车,最好能做到预先减慢速度再刹车,避免刹车过急,造成碰撞。
当车驶过有积水的街道时,要留意水深程度,如水深超过排气筒,便很容易令车辆熄火。如必须经过水深约半个轮胎的地方,便要先低档行驶,提高引擎转数,稳定油门,保持行车速度涉水而过。事后要留意脚刹车,因经过水浸后,刹车效能会减弱,如属鼓型者,便要拖手掣,先将刹车皮弄干,以防手制失灵。跟车也要较平时稍为远一些,以防前面车辆急刹车而造成意外。
转弯时也必须留意前面车辆,提防前面车辆过线,而自己亦应坚守自己车线,更不可因前车慢行,而加油超越前车。因为下雨路滑,视野不清,同时车轮很容易打滑,令车辆越过对方车线而发生意外。在高速公路上更不可超速驾驶,以防有车辆损坏,停在路旁,发觉稍迟,便会造成祸害。

Kontsevich能拿下Fields奖,当然不是闹着玩的。
Maxim Kontsevich,1964年出生,16岁时获数学竞赛全苏联第二名,85年从Moscow
大学毕业(没拿到本科学位),然后在莫斯科信息传输研究所工作5年,其间他有
很多时间花在音乐上,还在业余的法语强化班上认识了后来的夫人Rosanova。
插一句,Drinfeld得菲尔兹奖的工作是在低温物理研究所作出的,可见苏联的
学术环境有其独到的一面。
1985-1990是苏联政治文化大动荡的时期,许多苏联科学家离开了苏联,包括
Galfand去了Rutgers,Drinfeld去了Chicago,Margulis和Zelmanov去了Yale。
Kontsevich后来说他自己在这段做数学的时间非常少,但他还是坚持在数学上
做出了不少好的工作。当然和他后来的工作没法比。
(一)Max-Plank研究所,一生的转折点
1990年德国波恩大学Max-Plank数学研究所邀请他访问3个月,就在他准备回莫斯科
的之前,他参加了Max-Plank研究所的一个为期5天的国际会议,第一个报告是
Atiyah,介绍了Witten的一个曲线模空间相交数的猜测,Kontsevich放弃几个晚上
参加宴会的机会,想出了一个证明的思路,在会议结束前,Kontsevich报告了他的
想法,引起很大的反响。Max-Plank研究所所长Manin于是把他的访问期限
延长到了3年。这是Kontsevich一生的转折点,一年后他就完全证明了Witten猜测,
还证明了两个量子重力模型的数学等价性,开始跻身世界一流数学家行列。
就是下面两篇文章
[1]Intersection theory on the moduli spaces of curves,
Func. Anal. Appl. 25, No 2, 123-129(1991)
[2]Intersection theory on the moduli spaces of curves and the matrix
Airy function, Comm.Math.Phys. (1992) 147, 1-23
1992年Bonn大学授予Kontsevich博士学位。在Max-Plank研究所期间Kontsevich还
到Harvard,Princeton,Berkeley,Rutgers等大学访问。
Kontsevich的数学天赋展露无遗,下面这片文章引入了著名的Kontsevich积分,
并用之构造了新的扭结不变量。是目前公认的扭结分类最有效的不变量。
[3]"Vassiliev's Knot Invariants."
Adv. Soviet Math. 16, Part 2, 137-150, 1993.
(二)关于Gromov-Witten不变量
1993年的时候阮勇斌和田刚合作发表了一篇重量级的文章
Mathematical Theory of Quantum Cohomology,其中证明了量子上同调环的
结合律,并且对一类所谓半正定辛流形构造了后来被称为Gromov-Witten class
的不变量。他们的工作主要是基于Gromov的辛流形伪全纯曲线的开创性工作和
Witten在拓扑sigma模型方面的一些物理思想。Gromov-Witten不变量的叫法
最早应该是Kontsevich和Manin的文章
[4]Gromov-Witten classes, quantum cohomology, and enumerative geometry
Comm.Math.Phys.,164:3 (1994), 525-562
Kontsevich和Manin推广了Ruan和Tian的工作,并且给出了GW不变量的全新解释,
他们的文章有不严格的地方,有一些是“直觉上”和“概念上”的论证,留下了
被人攻击的口实。但其中的许多思想还是很值得研究的。“严格性”是数学家一
直遵循的一条戒律,但现代数学的发展,以及物理学思想对数学的影响日益显著,
特别是某些物理学家,可以从直观的物理想法上预测深刻的数学结论,然后把证
明的细节抛给数学家们。似乎在许多大家看来,想法是最最要紧的,技巧嘛,只
要想法对头,总能推出来的拉。
其实Kontsevich等人的文章还是很推崇Ruan和Tian的工作的。也看到过有人用
Gromov-Ruan-Witten不变量的,反正同行是清楚Ruan和Tian的贡献的。就象提到
Atiyah-Singer指标定理,人们也不会忘了Hirzbruch和Bott一样。
GW不变量有很多问题现在还是研究热点,特别是C.Taubes的工作
建立了GW不变量和SW不变量的联系。
(三)同调镜象对称,离菲尔兹奖一步之遥
Kontsevich最重要的工作之一同调镜象对称是在1993年作出来的,Kontsevich那时
在Berkeley任教。
镜象对称是弦论研究里发现的关于3维Calabi-Yau流形的对偶关系,物理学家用
镜象对称原理可以预测射影流形上曲线的条数公式,这个是意大利老一辈代数几何
学家就研究过的问题,但是难度太大,一直没有进展。没想到却在物理上发现了
一线曙光。一下子镜象对称就成为弦论里研究最多的分支,但是直到Kontsevich的
工作出炉以前,这个领域里到处都是猜测,只有一些零星的结果,特别是对于镜象
对称的数学解释没有一点头绪。
Kontsevich的以下两篇文章是巨大的贡献。
[5]Enumeraion of rational curves via torus actions, preprint,1994
[6]Homological algebra of mirror symmetry
Proceedings of the International Congress of Mathematicians, Zurich (1994)
vol. I, Birkhauser (1995) 120-139
他给出了几个射影流形上曲线条数的公式,用计算机验证的结果和物理上预测的结果
完全一致。他还用Fukaya范畴给出了镜象对称的一个数学解释,
称为Kontsevich Programm,里面除了复杂的推导,还有许多的conjecture,直到现在
都还没法完全搞懂,但人们依然相信Kontsevich的这套理论是站得住脚的。后来
Strominger,Yau,Zaslow从另一个角度给出镜象对称的数学解释,成为现在研究的很热的SYZ猜想。
Kontsevich在1994年苏黎世数学家大会上做一小时报告,内容就是上面的文章[6]。
这时候年仅30岁的Kontsevich已经是公认的国际上最杰出的年轻数学家了。
(四)远赴巴黎,终获桂冠
Kontsevich的弟弟是美国San Francisco的计算机视觉专家,Kontsevich本来已经打算
在Berkeley买一套房子终身定居了,这时候巴黎高等研究所邀请他担任终身教授,
那时侯IHES只有4位终身研究人员,其中有两位俄国人,Mikhael Gromov和
Nikita Nekrassov,加上那里不用教书,巴黎又是世界上数一数二的数学中心,
Kontsevich于是离开了对他再三挽留的加州Berkeley分校,成为IHES有史以来最年轻的一位终身教授。
Kontsevich在巴黎期间继续有好的工作问世,代表作是
[7]Lyapunov exponents and Hodge structures
in "The mathematical beauty of physics: in memory of Claude Itzykson"
(5-7 juin 1996, Saclay) J.M.Drouffe and J.B.Zuber (Eds.)
Advanced series in mathematical physics (1997) 24, 318-332
[8]Deformation quantization of Poisson manifolds
preprint IHES/M/97/72 (1997)
[9]Operads and Motives in Deformation Quantization
Lett. Math. Phys. (1999) 48, 35-72
[10]with Y.SOIBELMAN
Homological mirror symmetry and torus fibrations
in "Symplectic geometry and mirror symmetry",
K.FUKAYA, Y.-G.OH, K.ONO, G.TIAN (Eds.) World Scientific (2001) 203-263
和一些大家一样,Kontsevich的一些文章只有预印本,但这并没有太大的影响,网上
都有的。
比如那个Voevodsky在1996年证明Milnor猜测的文章至今未发表
http://www.math.uiuc.edu/K-theory/0170/
还有L.Lafforgue的弟弟V.lafforgue证明Baum-Connes猜测的文章也没有发表
http://www.math.jussieu.fr/~vlafforg/
他们可能是想把文章做的完善一点再投吧。
终于在1998年的国际数学家大会上,Kontsevich和剑桥大学的Borcherds,Gowers,
Harvard的Mcmullen一起获得菲尔兹奖。听说Kontsevich在Moscow大学的老师Gelfand
为Kontsevich的获奖出了很大的力,这个其实无可厚非。毕竟只有获奖者自己的实力
才是能够征服挑剔的菲尔兹奖Commitee members的唯一武器。

Airy function, Comm.Math.Phys. (1992) 147, 1-23
1992年Bonn大学授予Kontsevich博士学位。在Max-Plank研究所期间Kontsevich还
到Harvard,Princeton,Berkeley,Rutgers等大学访问。
Kontsevich的数学天赋展露无遗,下面这片文章引入了著名的Kontsevich积分,
并用之构造了新的扭结不变量。是目前公认的扭结分类最有效的不变量。
[3]"Vassiliev's Knot Invariants."
Adv. Soviet Math. 16, Part 2, 137-150, 1993.
(二)关于Gromov-Witten不变量
1993年的时候阮勇斌和田刚合作发表了一篇重量级的文章
Mathematical Theory of Quantum Cohomology,其中证明了量子上同调环的
结合律,并且对一类所谓半正定辛流形构造了后来被称为Gromov-Witten class
的不变量。他们的工作主要是基于Gromov的辛流形伪全纯曲线的开创性工作和
Witten在拓扑sigma模型方面的一些物理思想。Gromov-Witten不变量的叫法
最早应该是Kontsevich和Manin的文章
[4]Gromov-Witten classes, quantum cohomology, and enumerative geometry
Comm.Math.Phys.,164:3 (1994), 525-562
Kontsevich和Manin推广了Ruan和Tian的工作,并且给出了GW不变量的全新解释,
他们的文章有不严格的地方,有一些是“直觉上”和“概念上”的论证,留下了
被人攻击的口实。但其中的许多思想还是很值得研究的。“严格性”是数学家一
直遵循的一条戒律,但现代数学的发展,以及物理学思想对数学的影响日益显著,
特别是某些物理学家,可以从直观的物理想法上预测深刻的数学结论,然后把证
明的细节抛给数学家们。似乎在许多大家看来,想法是最最要紧的,技巧嘛,只
要想法对头,总能推出来的拉。
其实Kontsevich等人的文章还是很推崇Ruan和Tian的工作的。也看到过有人用
Gromov-Ruan-Witten不变量的,反正同行是清楚Ruan和Tian的贡献的。就象提到
Atiyah-Singer指标定理,人们也不会忘了Hirzbruch和Bott一样。
GW不变量有很多问题现在还是研究热点,特别是C.Taubes的工作
建立了GW不变量和SW不变量的联系。
(三)同调镜象对称,离菲尔兹奖一步之遥
Kontsevich最重要的工作之一同调镜象对称是在1993年作出来的,Kontsevich那时
在Berkeley任教。
镜象对称是弦论研究里发现的关于3维Calabi-Yau流形的对偶关系,物理学家用
镜象对称原理可以预测射影流形上曲线的条数公式,这个是意大利老一辈代数几何
学家就研究过的问题,但是难度太大,一直没有进展。没想到却在物理上发现了
一线曙光。一下子镜象对称就成为弦论里研究最多的分支,但是直到Kontsevich的
工作出炉以前,这个领域里到处都是猜测,只有一些零星的结果,特别是对于镜象
对称的数学解释没有一点头绪。
Kontsevich的以下两篇文章是巨大的贡献。
[5]Enumeraion of rational curves via torus actions, preprint,1994
[6]Homological algebra of mirror symmetry
Proceedings of the International Congress of Mathematicians, Zurich (1994)
vol. I, Birkhauser (1995) 120-139
他给出了几个射影流形上曲线条数的公式,用计算机验证的结果和物理上预测的结果
完全一致。他还用Fukaya范畴给出了镜象对称的一个数学解释,
称为Kontsevich Programm,里面除了复杂的推导,还有许多的conjecture,直到现在
都还没法完全搞懂,但人们依然相信Kontsevich的这套理论是站得住脚的。后来
Strominger,Yau,Zaslow从另一个角度给出镜象对称的数学解释,成为现在研究的很热的SYZ猜想。
Kontsevich在1994年苏黎世数学家大会上做一小时报告,内容就是上面的文章[6]。
这时候年仅30岁的Kontsevich已经是公认的国际上最杰出的年轻数学家了。
(四)远赴巴黎,终获桂冠
Kontsevich的弟弟是美国San Francisco的计算机视觉专家,Kontsevich本来已经打算
在Berkeley买一套房子终身定居了,这时候巴黎高等研究所邀请他担任终身教授,
那时侯IHES只有4位终身研究人员,其中有两位俄国人,Mikhael Gromov和
Nikita Nekrassov,加上那里不用教书,巴黎又是世界上数一数二的数学中心,
Kontsevich于是离开了对他再三挽留的加州Berkeley分校,成为IHES有史以来最年轻的一位终身教授。
Kontsevich在巴黎期间继续有好的工作问世,代表作是
[7]Lyapunov exponents and Hodge structures
in "The mathematical beauty of physics: in memory of Claude Itzykson"
(5-7 juin 1996, Saclay) J.M.Drouffe and J.B.Zuber (Eds.)
Advanced series in mathematical physics (1997) 24, 318-332
[8]Deformation quantization of Poisson manifolds
preprint IHES/M/97/72 (1997)
[9]Operads and Motives in Deformation Quantization
Lett. Math. Phys. (1999) 48, 35-72
[10]with Y.SOIBELMAN
Homological mirror symmetry and torus fibrations
in "Symplectic geometry and mirror symmetry",
K.FUKAYA, Y.-G.OH, K.ONO, G.TIAN (Eds.) World Scientific (2001) 203-263
和一些大家一样,Kontsevich的一些文章只有预印本,但这并没有太大的影响,网上
都有的。
比如那个Voevodsky在1996年证明Milnor猜测的文章至今未发表
http://www.math.uiuc.edu/K-theory/0170/
还有L.Lafforgue的弟弟V.lafforgue证明Baum-Connes猜测的文章也没有发表
http://www.math.jussieu.fr/~vlafforg/
他们可能是想把文章做的完善一点再投吧。
终于在1998年的国际数学家大会上,Kontsevich和剑桥大学的Borcherds,Gowers,
Harvard的Mcmullen一起获得菲尔兹奖。听说Kontsevich在Moscow大学的老师Gelfand
为Kontsevich的获奖出了很大的力,这个其实无可厚非。毕竟只有获奖者自己的实力
才是能够征服挑剔的菲尔兹奖Commitee members的唯一武器。

Poisson's ratio n is the ratio of transverse contraction strain to longitudinal extension strain in the direction of stretching force. Tensile deformation is considered positive and compressive deformation is considered negative. The definition of Poisson's ratio contains a minus sign so that normal materials have a positive ratio.
n = - etrans / elongitudinal
Strain e is defined in elementary form as the change in length divided by the original length.
e = DL/L.
