今天又是风又是雨,我琢磨着大抵5天没见到Mr Sunshine了,据说英国4月就别想见到Mr Sunshine了。在假期里,除了复习数学,还是复习数学,不过也看些闲书,今天看完了Gibbs写的The Life of Schubert,挺不错的,文笔也很好,具有权威性,作者还是The Cambridge Campanion to Schubert的主编。上次有人评论中提到了冯友兰先生,不禁让我想起他写的“阐旧邦以辅新命,极高明而道中庸。”我在这里也没中文书看,有时也只能自己回忆回忆脑袋里头的东西,背背,念念,赏玩赏玩。三句对联,向大家介绍:

(一)世事沧桑心事定,胸中海岳梦中飞

(二)岂可尽如人意,但求无愧我心

(三)认真,但不能太认真,应适时而止;看透,岂可以全看透,须有所作为。  横批:看待人生

第一句为20年代名满天下的梁启超书赠美国归来的20出头的谢冰心之联,一直挂于冰心客厅。我的感觉是工整,有气势。任公写什么东西都是气势压人,大家有兴趣可以看看少年中国完全版,排比句是10句一来的。
第二句为弘一大师李叔同所写,我第一次读到,是我在贵州省贵阳市郊的一处山间寺庙,旁还有Dr Sun Yat-sen写的一句:“佛法有时可以解科学之偏。”也挺耐人寻味的。
第三句的作者大概你们都不知道,这是非常可惜的,他就是现年93岁高龄的世界发展经济学之父张培刚先生,他早年毕业于武汉大学,创造了许多第一,第一个拿到哈佛大学博士学位的武汉大学毕业生,三年一度的留美庚子赔款考试全国第一,连续三年武汉大学法学院考试第一。第一个,也是迄今为止唯一一个获得哈佛威尔迅奖的亚洲人,这被誉为经济学的小诺贝尔奖,张先生当时同年或奖的萨缪尔迅后来就获得了诺贝尔奖,提出和张先生相同理论的刘易斯也获得了诺贝尔奖,但张先生49年回国后,下放农村基层劳动三十年,浪费了后半生,我是在《大家》节目看到采访他的,是我所看过的所有《大家》节目中对我感触最深的,他如果留在美国,70年代就或许就能拿诺贝尔奖了,一个人的命运在历史的面前是多么的无奈,所以这句普通的而又饱含哲理的对联,如果你了解张先生的坎坷人生,它有着多么重的分量。

太少更新,实在是对不起大家。我一次与老友邓勇在msn上遇到,他说他在交大连读班一周40个学时,昏天黑地,我于是揣测另一个姓邓的老友日子也不会滋润到哪里去了。相比之下,我是惭愧的很,这里轻松多了,我们已经在Easter Vacation了,一放又是一个月,了不得。不过这个月不能太多看闲书,毕竟下学期要考试了,一年才考一次,谁会不胆战心惊呢?就连这里的英国学生也各个都复习迎考了,好象又是一次全国联赛,不象在国内考试多得都麻木了。这两天是这里的科技节,有不少好的讲座,我还碰到了写Fermat's Last Theorem一书的作者Simon Singh,他还写过Big Bang等等,我想有些人大概读过中译本罢。昨天一个宇宙学的讲座,我算是第一次去了Carvendish Laboratory,想当年王来君反反复复讲,不过现在已非当初Maxwell时代的实验室了,旧址现在成了本科生上课的地方,上世纪70年代在west Cambridge开辟了新址,环境相当的好。昨天在池塘边看到许多许多的鸭子,还有不知名的鸟儿。我在这里的一个感受是,中国现在发展的很好,尤其是上海,到过上海的人都用amazing来向我形容,Coo Ching是马来西亚人,她说她去上海之前根本没想到上海如此好,不过上海还是有许多地方环境不干净,这是最大的缺陷。不知道为什么,看到那么多鸭子和鸽子,我的本能的反应是鸭子可以做老鸭汤,鸽子嘛烤乳鸽很不错的。也难怪,中国是饮食大国,英国好象事物也蛮出名的,不过是以糟糕闻名的。中国人大抵是全球最讲究吃的民族了,这里我们有时打招呼,无外呼how are you doing或者说说天气,我们中国人就不同了,一开口就是“晚饭吃过了没?”于是一切都和吃沾上了边,也许我们看到不知名的鸟也诧异这种鸟可以怎么吃法呢?最近经常和孙勋交流,他的感慨就是吃不好,吃不饱。说到吃,我又想到这个学期去参加一个朋友Elizabeth的21岁生日,首先说来罢,中国大多过20岁生日,这里的英国学生都热衷于过21岁,Tim说因为21岁象征成年了,那倒也不错,网上多得是什么18岁以下,21岁以下诸类云云。这是一个birthday party,是晚餐,我也很不清,究竟要送怎样的礼,后来咨询了Tim,这里生日聚会,最多送一张贺卡,原因便也很自然了,因为尽管是她生日,我们却各自买单,要命的是,结束时我们还不是付给老板,而是一一走到Elizabeth面前付钱给她,她呢,到好,一张早已列好的名单,付一个,名字旁勾一个,再给你一声再见。在中国委实不可想象。我争取以后多贴些图片,这样大家可以有个更直观的认识。

Just as Ping asked, I'd like to write some explanations about my courses for this term.
Firstly,Dynamics is the only compulsory physics lecture this year. However, it is quite different from the mechanics course for natural science students. Dynamics basically covers the topics of mechanics and teaches us how to use mathemaitcal methods to cope with physical problems, which is an applied mathematics course. In Cambridge, there're 2 departments for mathematical science, one is pure mathematics and statistics, the other is applied mathematics and theoratical physics, where Stephen Hawking is a  professor.
You might be interested to find out that there're quite a lot mathematics courses here, but actually, I think, they have litte difference from the faculty of mathematics in universities in China,(or maybe there're lots of differences, I'm not sure). For example, in China, I think the Vector Calculus, which is on the table below, you can see, belongs to analysis. It seems that every course belongs to Analysis in China whilst here, they are divided into several different course, one advantage of which, I guess, is that you will feel more clear about that particular area in mathematics. For instance, we've learnt double and triple integrations, operator identities, Green's 2 theorems, Stoke's Theorem and Laplace and Poisson Equation(which are 2 basic partial differential equations) in Vector Calculus. And I think the rest of this course in this term would be concentrated on Cartesian Tensors.
Analysis 1 is the first part of Analysis in China.(my Guess), which is basicallly about Weistrass thm, Mean Value Thm and so on and so forth.
Probability is another 1st year course, I don't intend to say something about that.
Groups, Rings and Modules is maybe the most difficult course to me this term. It is a 2nd year course, but we're recommended to take it this year and I also have supervisions for it. It feels really nice to take a 2nd year course, then, perhaps, I can choose some other courses next year. I've never read anything about groups theory before in China, so it is supposed to be difficult to me. The basic theory of groups have already been taught in last term's course "Algebra and Geometry". GRM this term at first discusses about Sylow's 3 theorems(If I were an examiner, I would definitely ask candidates to prove Sylow's theorems, I'm sure 99 per cent students cannot memorize that horribly long proof).
I'm really busy during the full term. I think I will try to write more in the near future.

I should say sorry that I haven't renewed my blog for quite a long time. It seems that nowdays everyones likes to upload his timetable for his courses in the semester. Maybe you guys are sort of interested in my timetable. Please see the following



         Monday   Tuesday   Wednesday   Thursday   Friday   Saturday
9-10       Groups,Rings and Modules    Groups,Rings and Modules    Groups,Rings and Modules  
10-11 Dynamics Probability     Dynamics Probability     Dynamics Probability    
11-12  Anaylisis 1  Vector calculus Anaylisis 1  Vector calculus Anaylisis 1  Vector calculus
12-1 Anthropology  Biography and History  Java Anthropology  Java  
             
4-5      History of math    History of math  


                                                                                                                                                                                                                                                              
Note: I also have 2.5 supervisions on average per week, which is a small class, one teacher and 2 students, talking about our homework.
