Why I Love Astronomy

    I am not major in astronomy, actually, my major has no business with astronomy. Therefore, astronomy is just my hobby and it continuously add passion and imagination to my daily life.

    It is unbelievable to a person who completely ignore the wonderful and grand starry heaven when he meets it by accident. In a cloudless and starry night, the shinning stars and blurry nebulae mounted in the faint Milky Way, depicting a magnificent and impressive picture which the one who have ever seen it will never forget. Actually I can’t describe it by words—each word is useless in front of the universe—what I can do is to appreciate and admire it. The feeling of the appreciation of it can only achieved by go outside and raise up your head. The starry heaven makes me think of the far distant world and lets me buried in its beauty.

    When I appreciate the starry heaven, what I see is not only the apparent beauty but also the long story behind it. I would think back to the previous period when the early scientists fearlessly explored the mysterious universe. I would imagine that what such astronomers like Kepler, Newton, Galileo and Tycho were thinking when they were staring at the formidable and fearful universe which they could not understand. The whole universe is a book, as Galileo had said. It was this book that inspired the early scientists to find and explore what they didn’t know and eventually created the theory to explain how the world worked and finally changed our world. The inspiration of exploring the unknown, I think, is a fascination of the universe.

    In 1990, the Voyager 1 took a picture of the Earth in 6 billion kilometers away from the it. In the picture, darkness occupied almost the whole space and there was a tiny and negligible dot in it: that is our home, the Earth. Every person who have seen this picture will be touched from the deep heart. Our Earth is just a dust in the universe, and we are so tiny and weak that may destroyed by some accident easily. As Carl Sagan wrote in his book:”Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.”We are tiny creatures, and no matter how advanced our technology is and how massive our knowledges are, we are nothing but a dust in the universe.

   So why do I love astronomy? The great philosopher Kant’s saying may deliver my reason:”Two things fill me with constantly increasing admiration and awe, the longer and more earnestly I reflect on them: the starry heavens without and the moral law within”.

Oh No

    I don't know what I want to write, but I know I want to write.

    I was busy during this whole week, since I had many lessons, and hardly had spare time. At the same time, there were many works which in robot team to be done, and the old member will check what we new members whether had all works done before Sunday. If not, maybe I would quit the robot team. In fact, it is Saturday 0 a.m. now, and I have just finished three fifth, so I can nearly sure I will not finish the job before deadline. Is that means I will quit the robot team? Yeah, maybe, but I don't think I will quit by force. But who knows.

    I have to admit that writing in English is very difficult and slow for me. My English is poor, I want to improve my English, so now I am writing in English in my blog. Oh I have digressed from main subject, so let's continue.

    Actually, I have gradually felt it boring in the robot team, and the degree is becoming deeper and deeper day by day. In my previous blogs I wrote that I longingly wanted to join the robot team and I was definitely sure I would learn many things in it. I did have learned many things in the robot team, for example, I have learned how to use various tool to make a thing which is painted in a paper, and I have learned how to control the robot by code. So to speak, I learned something which I could not learn from the book. However, I am gradually losing my interest in the robot team. There are many reasons, but I don’t exactly know the main reason, or, maybe it is various reasons that make me tired of it.

    First, I love free, and I hate restraint. I want to do what I want, rather than what I am assigned. During these three weeks, I would go to the robot team if I had spare times, or even in my class times. Sometimes I didn’t want to go to the robot team, because I want to do something I would like to do at that time. But I had to go to the robot team, because I have assignment to do and there was a deadline. Second, I am not doing what I am really interested in in the robot team. At present I just do some job which contains comprehending the code controlling the robot which was made by the last robot team, and programming my code to control the robot. I felt curious about that at the beginning, and I still feel it interest now, but I must say I don’t want to do that; what I really want to do at present is design circuits and learn more about electrical engineering.

    I nearly wanted to leave the robot team when I knew that my college had a program called “Information-Technology Talent Program” which is a program everyone can apply to participate in to learn how to do research and finally do a research by one’s own. It is what I want! So I quickly applied to participate in a team which is doing digital to analog conversion and SoC design. I hope I can join that team.

    What is the most important things in one’s life? I think it is happiness and unrestrained. I don’t want to give up easily and of course I hate give up. But considering it conscientiously, if abandon means throw away a bag which you don’t want to carry on the back and pick up a new one to continuing the journey, will you still hesitate and cease to advance? I think most person will choose the new bag.

    Whether or not, have a happy day and try your best to make yourself progress is the most essential thing. And if you steadily and surely live your every day, you will be astonished by what you have done when you look back.

一起吃苦的幸福

刚去机器人队开会,队长总结了下本周的工作进度,大家也发表了些自己的看法。会很快就开完了,接着大家就一起看一个小视频,叫《一起吃苦的幸福》,记录的是2004年西交第3届机器人队的参赛经历。这视频长约一个小时,记录了从组队到比赛结束100多天的工作生活。视频中看到,10年前的条件真的很艰苦,30多个队员每天吃住都在西校区的一个废弃的体育馆,哪像现在,机器人队有了自己的加工车间,条件非常的好。其实看的过程中还是特别感动的,视频中前辈们的吃苦耐劳,拼搏的精神真的很值得我学习。想想我的经历,自高中参加物理竞赛以来,已经很久都没有体会到那种拼搏,全身心投入的感觉了。

开会时说了,电路组的梯队队员因为太多,所以会被淘汰掉很多。感觉这段时间在这方面不是特别上心,如果想继续留在队里,就要多多努力了。

真的,好久都没有那种为了一件事而疯狂的感觉了。希望能留在队里,经历100天的磨砺,体会不一样的人生。

写些什么

不知为何ubuntu里chrome的翻墙插件zenmate用不了了,没办法只好来到win8下写。很郁闷,网上好多人都用goagent翻墙,不知为何我老是不成功。唉算了算了。

其实没什么好写的,但是感觉还是应该写些什么。

这段时间比较忙,每天如果不是在床上,就是在教室或是机器人队。忙什么呢,如果在教室,要么就是上课,要么就是看模电,话说我模电还没有看完,进度极慢,是不是又要开始怀疑我的智商了。在机器人队的话就是做任务,老队员一共安排了5次任务,我才做到第二个,下个星期天就要验收了,时间很紧啊。任务其实很简单,就是推导一些数学公式,什么码盘陀螺仪定位之类的,还有就是读代码,前几届,前前几届的代码,理解代码的含义,然后讲给老队员听。看代码看的我非常头疼,有些东西没有注释,很难看懂是什么意思,特别是一些数学处理,都不知道加这些有什么用。问老队员和其他队友交流时必不可少的,但也不能总问,不然人家就烦了,我也不好意思。感觉在机器人队效率很低,虽然几乎每天都在哪待上个几小时,但收获的东西很少,往往是对着一大串代码苦思冥想,不知所云。老队员都讲究自己琢磨,有次我问一大四老队员一个问题,他含糊地解释了下然后可能是想把我打发走,就说:“往年都是没有教这些的,都是自己琢磨”。听到这话我当然也就不好意思再问了。

自己琢磨确实非常重要,这我承认。作为机器人队的队员,必须对自己有高要求,必须有强大的读代码的能力,必须能够做到自己解决问题。但是,万事开头难,对新队员来说一切都是全新的,如果仅仅只给一些提示,就让新队员埋头读懂代码,我个人认为效率是很低的。自学的能力非常重要,这我完全同意,但是读老的代码和看一本书是不一样的。一本书有完整的知识结构体系,错误不多,初学者通过学习能够很快掌握其中的内容。但是老的代码却不同,虽然说没有错误,但是算法却有很多的冗余,不精练,有时还走弯路,猜测的时间大大多于思考的时间。当然了,我只是说效率低,并没有说做不到。作为新队员和低年级同学,我也不好说,因为他们当年也是这么过来的。不管怎样,既然是这样的要求,那我就要尽力去做,不然就只有被淘汰的份。

我觉得我喜欢过自由的生活。说实话,加入机器人队让我自由受限,我不喜欢这点。但是没有办法,如果每个人都自由,那最终只会导致任务完不成,比赛失败,所以说计划和纪律还是很重要的,特别是对要参赛的队伍来说。和我同组的有个大四的学长也是新队员,前天晚上我们一起回宿舍,他说那天下午下课他去洗了个澡,耽误了点时间,结果没有在7点之前到队里,然后就被一个老队员说“下次再迟到就别来了”。呵呵,我想想这感觉有点恐怖啊,哦他是主力队员所以要求更严格,我是梯队,所以没这么多的约束。

等等9点还有去队里开会。哎呀任务还有好多没有完成,想想就头大。

初入机器人队

本来在读英语,发现读不进去,干脆不读了,停下来写写刚加入机器人队的这段时间。

机器人队这个社团和其他的社团非常不一样,别的社团基本上是娱乐性质的,但机器人队是比赛性质的,在队里做的一切事情都是为了比赛服务。和其他社团不同的还有一点,就是其他社团基本上以大一大二为主,大三就几个;而机器人队则是以大三大四为主,大一大二只是去打杂,学学东西,但也有少数比较优秀的会成为主力。

还有一点,就是严格的制度。对于主力队员,要求只要是没课就必须来队里,像我这样的梯队队员,每周在队里待的时间不能少于16小时。还有很多约束,像在队里时不能打游戏,看视频,上社交网站之类的。这样就使得这个社团和其他的社团非常不一样,队长也把在队里的时间称为工作时间,真是有点像一个企业部门。

对于新加入的队员,会由老队员提供培训。这几天的培训就是钳工、做线插头、学充电。其实都不难,就是比较花时间,特别是钳工。钳工的培训中我第一次用锯铝机,第一次用大型电钻,第一次锯木头,还有很多我都叫不上名字的工具。做这些东西刚开始感觉特别难,锯个木头要锯老半天,用锯铝机时也特别害怕。我动手能力不怎么强,虽然好像小时候还行,但是越大感觉动手能力就越差。刚开始的几天做的不顺,所以好像就有点烦躁,也有点不想做,因为其实我对这些机械类的东西不怎么感兴趣。但是不做不行,这是任务,是要验收的,如果不想在6周之后被淘汰就要做好来。这几天我只要没课都会到队里,就是做这些培训,希望尽可能做好,一方面是不想被淘汰,一方面是这也是基本技能,总之多会点技能总没有害处。

在机器人队之外的时间我主要用来看模拟电路。现在感觉进度非常缓慢,一章都要看好久,我也不知道是怎么回事,反正就是很难理解书中的各种东西。也不知道是书的问题还是我的问题。我上一本看的是《工程电路分析》,美国人写的。国外的经典教材往往是很厚,很详细,每个知识点都讲得很细,所以我看那本书感觉非常轻松,也非常顺利,一章一章就这样过去,比较少遇到卡顿需要停下来好好想想的情况。本来是想找本国外的经典模电教材,但是图书馆的被借走了,没办法只好看国内的。可能是因为上一本电路看的太快,很多不是特别理解,毕竟我只是看,理解,没有做题,所以现在看模电由于基础不好而吃力。这也是这几天我比较烦躁的,因为一方面想抓紧时间多学点东西,想刚快把模电看完,还有很多的东西需要去学,一方面进度十分缓慢,每天就前进那么几页(看的时间也不是特别多)。

感觉是有点兼顾不过来。一方面想学习不能落下,一方面在机器人队有很多培训要做,还一方面想早些看模电这样的书(下学期才学模电),尽快提高我的水平,更好地在机器人队做事。这三方面很难全部做好,事实是我现在落下了几乎所有的课程,因为那些东西我现在根本学不进去,像复变、概率、量子力学、大物,我其实是有兴趣的,但是因为有做其他的事,导致我现在根本就不想学这些课。但对于落下的课程我也不怕,我相信这些都是很轻松能补上的。

就写这么多了,现在感觉时间真的很宝贵。

翻墙神器ZenMate

原来没有翻墙的需求,所以这么多年都没有翻过墙。其实最近也没什么翻墙的需求,纯粹是无聊,也想玩玩。如何翻墙百度一下有很多的方法,我起先用的是ssh,按照教程一步步做,非常不幸没有成功。我高中同学告诉我他用的是GoAgent,我又开始试,按照网上的方法又是一步步下来,又是非常不幸地没有成功。我真的很纳闷啊,为什么别人能成功我却老是不行,郁闷。我就问我那个同学怎么搞的。他说他刚好在人人上看到一个翻墙神器,叫ZenMate,于是就把地址发给我了。https://chrome.google.com/webstore/detail/zenmate-for-google-chrome/fdcgdnkidjaadafnichfpabhfomcebme

由于英语太垃圾,我都没看明白这个插件是干嘛的,隐隐约约就看到secure,以为是什么保护隐私之类的安全软件。不管怎样我安装了,然后继续捣鼓GoAgent,完全把那个插件忘了。

因为我是用firefox捣鼓GoAgent,第二天firefox还是不能翻,但是chrome却可以上facebook,我感到非常的奇怪。接着就恍然大悟,原来是那个插件啊。

菜单_002工具提示_003

默认是接入香港,网速很慢。点击中间的图片,变成右图。我设置成接入美国,网速一下就提高了好多。终于可以翻墙喽。

国庆啊国庆


转眼间国庆7天的长假就要结束了,感觉好快,也感觉都没做什么事情。这几天基本都待在宿舍里,看看书,读读英语,看看电影。一号那天我终于把《工程电路分析》看完了,呵呵。感觉这是很好的一本书,我从中学到了不少的东西,各种的分析方法。但是掌握地还不够,我只是看了一遍,没有做后面的习题,应该理解还不是特别的透彻。我想起来原来我都是狂做习题的,怎么现在一点都不想做了呢?我现在看书就是将全部内容理解一遍(当然有一些内容看了几遍还是无法理解)也不做习题,就这样一本就结束了。其实对于看书吧,怎么看关键在于你看这本书的动机。原来我看物理,会做极其大量的习题,是因为我要参加物理竞赛,只有大量做习题才能够提高。现在不同,我不参加什么竞赛,我只是想扩展我的知识面,再说,我觉得做大量的习题也没什么必要,现在大致理解了原理,以后看了更深层次的书会遇到原来那本书的内容,这样便可以加深理解。做题不也是为了加深理解嘛。

我被我们学校的机器人队录取了,这应该算是意料中的事。我非常希望能够在机器人队中学到东西,特别是书本上学不到的东西。7号晚上新一届的机器人队就要见面了,我很期待啊。

哦对了,我又跑到wordpress这来写博客了呵呵。为什么呢?唉,原先博客园的那个博客嘛,看着不怎么顺眼,而且那天我想添加html代码,居然不行!我就怒了,在网上找呀找看有什么好的博客,然后就发现了www.blog.com。接着我就注册了,捣鼓了好久。可是非常奇怪,昨天晚上开始一直到现在,那个网站都登不上去,所以我新建的博客也上不了了。没办法啊,谁叫我这么闲,于是又来wordpress了。其实不是特别想在wordpress开,因为这个网站在大陆被屏蔽了(郁闷,为什么这都屏蔽),必须要翻墙。翻不翻墙对我来说是没什么,可是写博客嘛,总是也希望别人看到,所以这样墙一下自然很多没翻墙的人看不到啦。不过也无所谓了,反正博客园也照常更新,内容是一样的呵呵。

Mysterious Cosmos

英语写作课的作业,写的不好,花了我很多的时间,留下来纪念下。

When I was a child, I liked to read an encyclopedic book named a hundred thousand why. The most interesting topic in this book I thought was about the cosmos. Every times I read them, I seemed to fly away from the Earth and went to the new and mysterious world in a far distance which is an unimaginable figure to today's astronomical technology. In a cloudless night, I would go to the building roof and raised my head to see that wonderful, grand, magnificent star field and beautiful, romantic, comely Milky Way. I would imagine that what that very far away world was like and whether or not there was life liked us. In the face of grand star field and many shiny stars I would felt that our lives and our Earth were so tiny and negligible and would be destroyed by a little accident easily. It just became a part of my life, liked eating and sleeping.

Soon, I was not content with just raise my head and use bare-eye — I wanted a telescope. I told my mother what I wanted and my mother refused it. That was in my expectation because an astronomical telescope was expensive not like a common toy. But I really wanted a telescope, I felt I was addicted to it. So I told my mother whether she could buy me a telescope if I had passed the exam which meant I would not take part in the high school entrance exam and could go to high school directly. My mother still said no because she thought that telescope would influence my study and made me backward. My mother still thought the telescope wasn't good for me, but I insisted. I told her why I wanted a telescope and told her that she should be happy because I just wanted a telescope not a game machine or smart-phone and the like which did influence my study. Eventually she gave up, and promised me if I had passed that exam she would buy me a telescope. Oh yeah, it seemed that there was a chance that I would own a telescope.

Months later, I passed that exam fortunately, thank god. Our family was happy about that because I was admitted by the best high school in our city in advance. So, my mother bought me a telescope on the Internet. Some days later, a large paper box which contained my hope and happiness was sent to my home. I was too impatient to wait to tear the paper box and found my beloved gift:though I had imagined what it was like many times, I was still astonished by its length and size — the tube was much longer than my arms, its diameter was just a little less than my palm, and its weight was much exceeded my expectation. There came another excitement when I assembled it:it was the largest gift I had ever got and it was a beautiful and imposing apparatus even just a little shorter than me!

After long and impatient wait, darkness came and stars began twinkling. I was impatient to carry my precious telescope to the building roof and assembled it quickly. Stars were glittering while my heart were beating and my hands were shaking. I was so excited that couldn't focus well. Eventually I saw those beautiful shiny stars through my telescope. Then galaxies and nebulae were all into my eyes clearly and I buried myself into the mysterious cosmos.

Nowadays when I am free and accidentally a cloudless night come, I will still go out and raise my head to see the grand and magnificent star field. I have took part in the astronomy organization in university and see, watch, observe the strange, mysterious, desirable cosmos through the telescope with my friends.
