光学实验

昨天在物理学院一楼演示试验室观察光学现象。先看了杨氏双缝干涉和杨氏单缝衍射。接着又看了几何光学中成像的一些现象,具体而言慧差,球差, 色差和畸变。
最后看了一下实验室的一个仪器。其结构是有正负两极。中间的高压级是一极,大地是另一极,二者组成闭合回路。当人手放到上面去时,人相当于大地,因而形成了一个通路。这就是本来均匀分布的电路在集中到人触摸处。(电路和磁路一样,并不是电路外没有电场,而是电场很小,近似认为为零。而磁性介质的磁导率往往不是很大,不足以使全部的磁场被约束在介质中,故而会出现漏磁现象。)
不过最近发现光学很难。经常上课想睡觉。老师讲的很抽象,一个概念刚接触就又跳到下一个概念去了。而且许多知识似乎不知道它的来龙去脉,只是介绍了知识点本身,不知道该怎么用它。比如复振幅,为什么要是变一个号。为什么要使sin前为负?
马上就要期中考试。回想这个学期,开学时的许多事情,还有电脑,还有评奖学金,还有咖啡,还有其它许多事情......一件一件似乎让我有些没有头绪。不过无论如何,有一点是很清楚的,那些事情浪费了许多原本应当用在学习上的时间。God blesses.

武汉的春天大概就是这样,细雨蒙蒙,像是一个朦胧的梦,淡雅而又恬静。在校园内的一处小憩,的确是一件很适宜的事情。在教学楼上,我坐在窗边看着窗外那绿色的草地,不禁想到生活。 生活本恬静而又自然。不需要特意的渲染和修饰。一切都在那个地方了。静静地,每个人都活在自己的世界中。 God blesses.

just a mistake

Yesterday I sent a message to a graduate student,and asked her something about love. Finally I got to understand that what I have been craving for is not love. I have failed to distinguish between the need to communicate with others and finding a lover.
Feeling connected is a natural need for many. But to be connected does not mean that you have to find a lover.
Time waits for no man. You should be devoted to your study.

a song

I heard "time to say goodbye" by accident. When I hear the music at the very first soundbite, I am deeply impressed by the song. It felt as if I had been in another world, a totally new and different world. The world was beyond description. It was like a place in dream. It made me think of the heaven.
More importantly, it makes feel that life is really precious and beautiful. What can be more important than life? Nothing else. To appreciate life means to make full use of the time. Beauty always exists. You should try hard for keeping the beautiful things remained. Behave yourself. God will watch over everyone.

REMEMBERING GRE VOCABULARY PLAN IN CRICIS

It is 6 days since I got home. What I have done have strayed from my original goal. I waste time again and again. It is not tolerable. And it should not be tolerated any more. Work hard. Never waste any time. And never do anything without knowing what you're doing.
God blesses.

a gathering

I met a old friend this morning. I felt some sense of... It's hard to define what actually I felt. But I know it's a sort of strong feeling. It is an indication of time. Old friends have to part. Old dignity have to be abandoned.
I do love the past very strongly. I wish I could experience that period of time again. Everytime when I think of the past I have some special feeling, like love. But I know it could not be love, because I'm not interested in any person. Instead I am quite interested in places, like the No.1 Senior High school. These places give me very wonderful memory. When I think of these places I feel some sense of sympathy.
Sympathy. It has been long with me. Sometimes I feel the sympathy for others sometimes for myself. Sometimes I like this kind of feeling for it can make me feel safe. I felt as if I was in my own castle when I sympathize myself.
I wonder why. The best answer I've ever thought of is that I am born to have such a feeling.
What is life?
This is a complicated question. Why are we live in this plannet and why are we here rather than anywhere else? Those are questions that I can never answer. How I wish God could help everyone overcome difficulties in life, though he does not exist.
Best wishes to all.

考试

这学期期末考试很差。我感觉自己对学习没有那么重视了。大一上的期末考试似乎使我误以为大学考试很简单。而实际上大学考试是很难的。学习态度很重要,学习时不要想自己怎么怎么样。想着自己学的东西,把内容理解,做到融会贯通。学习真的不是一件容易的事情。一定要努力,努力,再努力。

Life is not easy

Many a time I find myself idealized the life. The wrost thing is that I have made a wrong premise. I make myself to believe that I am a superior person. With this premise, I fail to sense the importance of working hard. And I alse fail to criticise myself. Usually when I fail an exam, I would complain that my fate is not good. Bad fate is frequently used as the excuse for my failure.
Hard working is the fundamental requirement of everything. No hard working means nothing.
QYD, you are not a god, nor a hero. You are an ordinary man. You should confront these difficulties. You should be realistic. Confront the reality, even when it brings you great pain.
What you really need to do is work hard.

杂感

未来是美好的,但需要付出汗水,也需要经历痛苦。但愿在新的学期里,我能专心学习,同时争取能考过体育。我希望能将时间好好利用,过的充实一些。

突然的感觉

I will go to school in a few days. But suddenly I'm struck by a kind of feeling. I couldn't tell what actually that kind of feeling was. But I felt some sense of ambitious in me. I hadn't felt so ambitious since the entrance exam. I had never blame myself for the result of the exam. Sometimes I think that is my destiny. I should obey it . But now I feel that it is my lazyness which led to the decline of selfconfidence and performance. The past is not to blame, what really matters is the present. I still have many dreams about the future. And they all require hardwork and selfdecipline. Work hard and keep it in mind that you can never be too hard to study.

新年

不经意间就要到大一下学期。得知大一下学期将开设物理课程,心里不免有几分茫然。
现在就快开学了,但愿我在新的一年里能改掉过去浮躁自满等坏毛病。
大学的时光是美好而又易逝的,珍惜上帝的恩赐吧!
