发信站: BBS 未名空间站 (Wed Dec 9 12:25:27 2009, 美东)
我一直不是非常理解hard sphere liquid的结构。
按理说这种体系中粒子间基本是无相互作用的,除非在粒子间相互碰撞时才会有无穷大
的排斥力。通过径向分布函数g(r)可以求得potential of mean force,进而求得
粒子间相互作用力的系综平均值f(r). 但这样就会觉得原先无穷大不连续的粒子间
瞬时作用力,取了ensemble average之后就变成了随r连续变化的f(r)。这一点我
不是非常理解。
另外,通常求径向分布函数g(r)

At very least,
How could a sphere intersect another circle at more than 3 points?
If so, this circle belongs to this sphere, I think? Since both the circle
and the plane which cut the sphere are fixed.
Can you give an example where a sphere intersects a circle at more than 3
points but this circle is not part of this sphere?

Consider any two points A and B on a sphere, which are symmetric w.r.t.
some great circle of this sphere. So there are two hemispheres. And I think
it could be shown that there always exists a family of cicrles parallelling
the great circle which covers one of the hemispheres without the given point
by some analytical geometry.So it's concluded that any sphere without two
points could be covered by a family of disjoint circles.
Now we just take the family of spheres centered at origin. Construct

Let me fill the gap to prove "A sphere with 2 points removed can be
partitioned with disjoint circles", and hope it will help.
One a sphere, let the 2 removed points be A and B.
(1) If A and B are opposite to each other (like north pole and south pole),
then the remaining sphere can be partitioned with circles that are
perpendicular to line AB.
(2) If A and B are not opposite to each other, let P_1 be the tangent plane
(to the sphere) at point A, and P_2 be the tangent plane at point B. Assume

choose are all on x-axis as shown in the graph, ie, those points should be 0
,2,4,etc, then do you have a sphere with radius .5 as one of your sphere? If
yes, this sphere would cut the first black cicle (the one closest to origin

东亚文明是多极世界文明体系中的一个重要组成,儒家文化也是东亚文明的内核,中国
大陆、以及香港、澳门和台湾、日本、韩国、新加坡及越南及等八个国家和地区,都对
儒家文化有一致认同感。参考“盎格鲁圈”(Anglo Sphere,盎格鲁圈,即指受英国自
由价值观影响的、讲英语的国家和地区,前身都是英国的殖民地,核心是英、美、澳大
利亚、加拿大和新西兰。)的提法,笔者提出“儒家圈”(Confucian Sphere),其内

You have to hand it to Barack Obama. He has unmasked in the most
thoroughgoing way the despotic propensities of the administrative
entitlements state and of the Democratic Party. And now he has done
something similar to the hierarchy of the American Catholic Church. At the
prospect that institutions associated with the Catholic Church would be
required to offer to their employees health insurance covering contraception
and abortifacients, the bishops, priests,... 阅读全帖

得到博士offer的本科生简历(挂网公开的,应该可以讨论把)在下面,先只请教下打动
发考题们给了博士offer的原因,别的不八卦:)哈哈
照说本科生得让发考题们认为极其有科研的潜质,才能打败无数硕士生,发考题们才
会直接给本科生offer直攻博士;
看这份简历,我的感觉是
1.本科成绩好,会读书
2.参加了很多国内老师的项目,参加了一些海外老师的暑期短期项目,有些学术锻炼和想
法,但无明显成果,可能人缘好,会来事;但不排除夸大自己作用的可能
3.得了一些奖学金,国内高校基本上成绩好加积极参加学校各项活动,对老师会来事,自
然就能得.
3.英语写的好
4.积极参加各种活动,精力充沛,勤奋,把自己的时间,安排的满满当当的,有废寝忘食的
倾向.
5.非常有计划性和目的性,经过几年奋斗,作为本科学生,已经达到面面聚到的无短板程
度.
作为本科生,这份简历无疑是优秀的;但是却无法直接得出极其有科研的潜质的结论;相
反无数硕士生申请攻博士,由于年龄大一些和工作经历,也许本科成绩绩点低一些,得的
奖学金项目少一些,但是有实践经验,多数还会有1-2篇海外(尽管可能级别和影响不高)
