港孩

港孩: "

葉一知

吾友黃明樂寫了一本叫《港孩》的書，絕！港孩這個題目，本人久不久談談，早已越來越看不過眼，難得阿樂將之成書，只不知道頑固和愛從集體平庸取暖的家長，能否有所領悟，頑石點頭。

所謂港孩，特徵如下：

1. 外表早熟，心智遲熟。
2. 很喜歡玩，但無甚興趣。
3. 對大部分事情最普遍的反應是沒有反應。
4. 擅於「看見」，不擅「閱讀」；擅於「收聽」，但從不「理解」。
5. 渴望被注意，但又沒有面對群眾的信心。
6. 什麼都不在乎不介懷不思考不要求，典型答案是：不知道。
7. 沒有責任感、沒有自理能力，同時也沒什麼好奇心和欲望。
8. 不珍惜學習，不嚮往長大，不怕悶，只怕辛苦。
9. 精於計算結果，毫不享受過程。
10. 本性善良，不吃人間煙火，當然也未經任何苦楚及傷害。

《港孩》歸納的這些特徵，一如港女，當然還有修正和發掘之可能，但大致上描述了今日的港孩是何種模樣。

《港孩》最令我深印象的一段，是有個學生，要向學校請假去旅行。但期終考試臨近，老師建議學生考完試才出發。豈料，學生那個學貫中西、衣冠楚楚的家長，怒氣沖沖來學校「理論」，不，是當場反枱，指著老師鼻尖說：「我個仔今次跟我參加國際會議，見的都是世界知名的外科聖手，這些大場面，你見過未？校內試，有咩咁巴閉？」

為甚麼會有港孩？答案當然是先有弱智的家長。這個家長弱智之處，在於他一邊認為面見外科聖手比校內試重要，一邊又送孩子去學校。按其還輯，其實只要多帶孩子參加學術會議，見多些外科聖手，不用讀書，將來至少也是個婦科聖手吧。但如果這位家長認為不讀書還是當不成聖手，於是把孩子送去學校，那考試當然重要啦。除了死人冧樓，我就沒見過有甚麼同學不校試也可以升班。考試也是學生的責任，如今家長施以身教，教導孩子不負責任，真如特區政府同樣邏輯弱智的宣傳廣告一樣：有樣學樣，一家人嘛。一群家長成了educated fools，很自然也教出另一班highly educated fools！一家人嘛！

但只怪責家長也不公平。《港孩》沒有交代這個學生沒有考試能否升班，但學校實在有責任不讓這種學生升班，至少也以理由不足(如果旅行可以不考試是合理的話，請愛惜孩子的家長們，每逢考試都報團，你的孩子一定愛死你)拒絕其請假。呵呵，但學校敢嗎？據我所知，絕大部分的學校對著這種家長都只求息事寧人，得過且過，默不作聲。無他的，這個孩子堅持請假不考試，學校有權不讓他升班，但得罪了這種家長，他們又會幫兒子轉校，直資的怕收生不足，其他的怕殺校，怎不投鼠忌器？

所以我們應該明白，為甚麼一大群學校會力撐校園驗毒，卻不敢對這種家長說不。因為我們只敢欺負年幼的學生，卻不敢向這種家長據理力爭。那些聲稱為孩子好而力撐校園驗毒的教育界人士，你們也敢為了孩子好、為了我們社會的未來棟樑，嚴斥此等弱智家長嗎？難道你們認為縱容一個不負責任的孩子，符合教育理念嗎？那真不知道那是甚麼樣的教育理念了。請記住，這種家長對青少年的危害，只會比索K更大，甚至是好學生也索K的根源，我們的社會又敢正視嗎？

誠如《港孩》一書所指，港孩之問題，非出於他們身上，而在於社會今日的主流價值觀，今日那種追逐比較而不是或不懂真正愛護孩子的家長，責任更大。

People Should do something Different, Bravely.

Leaner - Scholar

As a learner, when we face a huge amount of information, we have to squeeze them into few pieces. So, we can only memorize those pieces and apply them into different situations.

As a scholar, we have to expand those few pieces into huge amount again. Afterward, a professional was made.

This is it !!!

Writing Paradox

people are used to give judgement/conclusion, before they have the reasons.

students are taught to have reasons, then follow logic (the way of manipulate reasons), thus have judgement or conclusion.

in every writing lesson, teachers must teach you, write the sentence statement at the very beginning, which mean, you should have a judgement, before everything. even when you write down you outline, you are taught to have judgement/view point before.

This is totally wrong!!! we should write in an opposite way. start with reason, then conclusion.

Distinguish of HyperGeometric , Binomial and Poisson Distribution

First , Let me give definition of them by when to use.

HyperGeometric (HG) = when the events are not replaceable. ( like pick cards) i.e. events are related.

Binomial (BI) = when events are replaceable. ( like toss coins) i.e. events are not related (mutually exclusive)

Poisson ( pronounce: po song ) (PS) = when events are counted continuously and in term of interval. (like How many cars pass the lines in given time interval)

HG and BI are closely related as we can see, just a matter of replaceable or non-replaceable. But why PS also related?? Before, we should know HG and BI, how exactly they are related.

Lets take an example of cards drawing.we have 52 cards. the probability of pick 2 hearts out of 5 draws is:

5C2 * (13/52) (12/51) (39/50) (38/49) (37/48) = 0.27

or using Excel =HYPGEOMDIST(2,5,13,52)

because every time you pick up a card, there is 1 card less in the sample space.

how about we pick out 52 cards, all of them? of course, we will have 13 hearts, no more, no less.

HYPGEOMDIST(13,52,13,52) = 1

ok, now, if we have infinite number of cards, and, the proportion of heart is still a quarter, what is the probability of 2 hearts in 5 draws?

is HYPGEOMDIST(2,5,inf/4,inf) ???

since there are infinite number of cards, the statement of non-replaceable is making no sense. Thus, it become BI

5C2 (1/4) (1/4) (3/4) (3/4) (3/4) = BINOMDIST(2,5,0.25,0) = 0.26 little bit less, but it is NOT because the huge sample space reduced the chance.

OK, i assume, you got the idea that, if the sample space goes to infinite, or real large, HG is BI. i say, if sample space is 500 times larger than the pick up size, then, it is safe to use BI to replace HG.

We can related BI to PS now.

Let takes an example to show the different.

in 100 people, 30 are boys . the probability of getting 3 boys in 10 people is follow BI or HG more accurately.

if someone using Poisson, he is assuming that, there is probability that we can get 11 boys by picking 10 people out!!

One thing we can see is, in Poisson Distribution, the event of success (boy) should not be bounded by the sample space (people picked) . or we can say,

in Binomial, number of boys <= number of people picked.

in Poisson, number of boy can any number.

so, if the number of pick goes to infinite in a given interval, or counted continuously . thus, BI goes to PS.

one sample is monitoring, we detect signal in any time.

like the number of leak in 1 km of water pipe. first, the leakage is not bounded by the length of water pipe. Second, we pick event in every where. Thus, we use PS.

But if we divide the water pipe in 100 equal intervals, and we want to know how many intervals are leaking. thus we should use BI, or HG.

A short summery,

sample space = N (people, cards)

pick put size = n

target size = T (boy, heart)

interested size = x

HYPERGEODIST(x,n,T,N) = Probability of x heart out of n pick out, where there are T hearts and N cards, with out replacement.

BINOMDIST(x,n,T/N,0) = Probability of x heart out of n pick out, where there are T hearts and N cards, with replacement. ( when T/N is a constant, and N goes to INF, HG goes to BI )

POISSON(x, n T/N,0) = Probability of x heart out of N intervals, where nT/N is the mean. ( when nT/N is a constant, n and N goes to INF, HG or BI goes to PS )

Integrated Task

Author said, using cell phone on driving cause accidents, because driver’s attention was distracted. That’s why governments over the world have posted restriction on cell phone usage while driving. The restriction may vary in different places. Some are totally prohibited the use of cell phone during driving, some are allowed the use of cell phone with hand-free devices. In additional, automobile insurance will be lost if the accident is involved talking on cell phone.

However, the speaker stated that using of cell phone is not strongly related to car accident. Traffic accidents are also caused by other issues, like talking with passengers, eating, making up or even attend to children. A research on driver by video recorded driver’s behavior revealed that most car accident is mainly caused by different kind of distractions like looking at GPS device. At the end, speaker suggested that cell phone actually safe life or even reduced road accidents. Drivers can use cell phone to make emergency call, report road accident and possible road hazard.

What invention is the most important in 20 century? II

I believe electronic devices are the most important invention in 20 century. Because it is so close to our daily life and completely changed our society. Have you heard about EM bomb? It is a bomb that can burn out all electronic devices without killing people. Many governments are restricted that kind of bomb, although it is not harmful to human. We can see how important electronic devices affected us.

Electronic devices are important because of the programming power. A program can handle special situation when designed input was detected. Like in the supermarket, when the bar code scanner detected a code, the price and the information of the goods were shown up in the screen and calculated the total price. That is the power of programming. Nowadays, nearly almost anything can be programmed. And it saves a lot of time.

Electronic devices also have the power of calculation. It can do million and million calculations in just 1 second. The influence is deep and width. In logistic industry, hundreds and hundreds of goods and cargos are needed to be transported. With the help of electronic devices, every goods and cargos are labeled with a signal emitter, when someone needs to check how many things are in there, they simply check how many signals were received and compare it to the database. It cannot be done within few seconds in the past. Another example is research and stock markets. Researcher can now study some difficult and complex problem by the aid of computers. The stock markets need to process a lot of trading in a short time. All of this cannot be done without electronic devices.

Today, we can see electronic devices are everywhere. In the car engine to cell phone, from shopping malls to stock markets, from entertainments to research fields, none of these are able to work in modern society without it, not just because it is convenient, but also it can handle massive calculation.

An American or a chinese roommate.

If I can choose, and if I can only have 1 single roommate, then I prefer to have an American roommate, rather than a Chinese. It is because an American roommate can bring culture different and inspire new ideas. Although living with a roommate who has same culture is easy, because we share similar living style, it wasted a chance to learn something new. And most importantly, throughout my life, i probably will work and live with Chinese rather than American. So it is a very valuable time for having an American roommate.

As we know, every culture has advantages and disadvantages. In order to discover and improve our weakness, the best way to do is through comparison. I am a Chinese, who has a long history behind of me, while compare to an American, they hay rather short history. My long history background may possibly make me conservative, like obey authority, lack of innovations and not independent, while our American counterpart may be totally different. I believe living with an American will be a wonderful experience.

Nowadays, due to the economic bloom in china, many westerners proposed an imaginary threat from china. It is natural to be afraid in front of something unknown. So, I believe it is because we do not understand each other very well. The best way to know each other is living together. Therefore, having an American roommate is not a good for me to learn from American, but also the best way to let American learn from me. I believe through the culture exchange, both of us will learn a lot, and most importantly, friendship and trust and be found.

All in all, I will choose an American roommate rather than a Chinese. Not because I like the western style, but it is a good chance to let 2 cultures fusions together.

What invention is the most important in 20 century?

A truly important invention should not only bring us good things, but also bad things, and also make a deep influence to us. Therefore, I think airplane is the most important invention in the 20th century. Although it is not a new idea that moving in the sky, airplane is realized in this century. At the beginning, airplane is only for army. But after while, it become commercialized that not just transporting goods or letters but also people.

Airplane is so important because it lets people able to go around the earth fast. One direct effect is the tourism. People start to travel, understand different culture and make friends at different nations. This brings understanding and open up mankind’s mind. People now know that every people, cultures are valuable. No one is superior then others. Now a day, we will solve conflict by negotiation rather than fight. This is because of understanding.

Airplane also transports goods as well. California fruits can be tasted in Hong Kong at the same season. People can now do business around that world, because good can be transported fast. The most important influence is that, life-saving material can be delivered faster and quick into area of natural disasters, incidences and accidents.

Airplane also gives a lot inspiration. When we start to explore the sky, we are able to study our planet from above. We are now in a better position to predict the weather. By take photographs of our earth, we are able to “see” the human activities, like urban expansion, water reservation.

Besides of the good it brought, there is also bad thing. We can see this in the World War II. That war is the first time human fight in the sky. Troops and booms can now be transported fast and conflict and dead may happen without any prediction.

Airplane has already changed our way of life in many different aspects. From food to cloth, form business to friends, either good or bad are all affected by this convenience and fast machine. Next time, when traveling around, think about airplane.

Water-flow meter on tape

That is!

show people how much volume of water being flowed in total, and also in that time. also, cover to money.

if better, can set a control on water flowed. after that much of water used, the tape will no longer function until next month or next period.

Over Time

employers should tell employees about overtime earlier if they knew or expected.

it is not just because it is a duty, but also a good communication and labor relationship, that help each other to defend their rights and maximum the happiness.

Many employers may consider it is useless to say so by 2 main reasons. 1, if announced earlier, then labor can refuse or excused. 2, if say nothing, it is higher chance that labor will overtime because of avoiding direct conflict.

1, it is the employer duty to arrange the time best to avoid overtime. (that's one of the reason why overtime have higher payment than normal working hours.) employers should and must not transfer this duty to employees.

2, in fact, there is no direct conflict even by saying nothing for overtime. since, employee can simply leave on the off-time. because they have done there duty and completely fulfilled it (not applicable for task-base duty).

Order; Reader's Digest

People are so worried about what they eat between Christmas and the New Year, But they really should be worried about what they eat between the New Year and Christmas.

Change; Reader's Digest

Big changes in our lives are more or les a second chance.

Things do not change; we change.

the main dangers in this life are the people who want to change everything...... or nothing.

If you want to make enemies, try to change something.

Start by Starting.

People often overestimate what will happen in the next two years and underestimate what will happen in ten.

Do or not do. There is no try.

never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.

Friend; Reader's Digest

You find out who your real friends are when you're involved in a scandal.

A real friend is one who walk in when the rest of the world walks out.

A true friend is someone who thinks that you are good egg even though he knows that you are slightly cracked.

The best mirror is an old friend.

Everybody wants to ride with you in the limo, but what you need is somebody who will take the bus with you when limo break down.

Every Business is built on friendship.

One freind in a lifetime is much; two are many; three are hardly possible.

Leadership; Reader's Digest

Great leaders are almost always great simplifiers.

It's hard to lead a cavalry charge if you think you look funny on a hourse.

Good leadership requires you to surround yourself with people of diverse perspectives who can disagree with you without fear of retaliation.

It takes 20 years to build a reputation and five minutes to ruin it. if you think about that, you'll do thing differently.

The person who knows "how" will always have a job. The person who knows "why" will always be his boss.

Being powerful is like being a lady. If you have to tell people you are, you aren't.

Animals ; Reader's Digest

Dogs look up to you; Cats look down on you; pigs treat you as equal.

Animals are such agreeable friends - they ask no questions, they pass no criticisms.

You cannot look at a sleeping cat and feel tense.

A horse gallops with his lungs, perseveres with his heart, and wins with his character.

We give dogs time we can spare, space we can spare, and love we can spare. In reture, dogs give us their all. It's the best deal man has ever made.

No one can feel as helpless as the owner of sick goldfish.

Dogs come when they're called; Cats take a message and get back to you later.

a Speech

Speaker: Patrick Henry (1736 - 1799)

Date : March 23rd, 1775

Place: Virginia

議長先生:

我比任何人更欽佩議會証上發言的先生們的愛國(按:不是愛黨)情操和才能. 但是, 對同一事物的看法往往因人而異. 因此, 儘管我的觀點與他們截然不同, 我還是要毫無保留地, 自由地予以闡述, 並且希望不要因此而被視為是對先生們的不敬.現在不是講客氣話的時候, 擺在議會代表們面前的問題關係到國家的存亡. 我認為, 這是關係到享受自由還是遭受奴役的大問題, 而且正由於它事關重大, 我們的辯論必須做到各抒己見. 只有這樣, 我們才有可能弄清真相, 才能不辜負上帝和國家賦予我們的重任. 在這種時刻, 如果怕冒犯別人而沉默不語, 我認為就是叛國, 就是對比世間所有君主更為神聖的上帝的不忠.

議長先生, 對希望抱有幻覺是人的天性. 我們容易流於閉起眼睛不願正視痛苦的現實, 並傾聽海妖惑人的歌聲, 讓她把我們化作禽獸. 在為自己而艱苦卓絕的鬥爭中, 這難道是有理智的人的作為嗎? 難道我們願意成為一個對於獲得自由這樣休戚相關的事卻視而不見, 充耳不聞的人嗎? 對我來說, 無論在精神上有多麼痛苦, 我仍然願意了解全部事實, 真相和最壞的事態, 並為它做好充分的準備.

我只有一盞指路明燈，那就是經驗之燈。除了過去的經驗，我沒有什麼別的方法可以判斷未來。而依據過去的經驗，我倒希望知道，10年來英國政府的所作所為，憑什麼足以使各位先生有理由滿懷希望，並欣然用來安慰自己和議會難道就是最近接受我們請願時的那種狡詐的微笑嗎？不要相信這種微笑，先生，事實已經證明它是你們腳邊的陷階。不要被人家的親吻出賣吧！請你們自問，接受我們請願時的和氣親善和遍布我們海陸疆域的大規模備戰如何能夠相稱？難道出於對我們的愛護與和解，有必要動用戰艦和軍隊嗎？難道我們流露過決不和解的願望，以至為了贏回我們的愛，而必須訴諸武力嗎？我們不要再欺騙自己了，先生。這些都是戰爭和征服的工具，是國王采取的最後論辯手殷。我要請問先生們，這些戰爭部署如果不是為了迫使我們就範，那又意味著什麼？哪位先生能夠指出有其他動機？難道在世界的這一角，還有別的敵人值得大不列顛如此興師動眾，集結起龐大的海陸武裝嗎？不，先生們，沒有任何敵人了。一切都是針對我們的，而不是別人。

他們是派來給我們套緊那條由英國政府長期以來鑄造的鎖鏈的。我們應該如何進行抵抗呢？還靠辯論嗎？先生，我們已經辯論了10年了。難道還有什麼新的御敵之策嗎？沒有了。我們已經從各方面經過了考慮，但一切都是枉然。難道我們還要苦苦哀告，卑詞乞求嗎？難道我們還有什麼更好盼策略沒有使用過嗎？ 先生，我請求你們，千萬不要再自欺欺人了。 為了阻止這場即將來臨的風暴，一切該做的都已經做了。 我們請願過，我們抗議過，我們哀求過；我們曾拜倒在英王御座前，懇成他制止國會和內閣的殘暴行徑。 可是，我們的請願受到蔑視，我們的抗議反而招致更多的鎮壓和侮辱，我們的哀求被置之不理。 我們被輕蔑地從御座邊一腳踢開了。 事到如今，我們怎麼還能沉迷於虛無縹渺的和平希望之中呢？ 沒有任何希望的餘地了。 假如我們想獲得自由，並維護我們長期以來為之獻身的崇高權利，假如我們不願徹底放棄我們多年來的鬥爭，不獲全勝，決不收兵。 那麼，我們就必須戰鬥！ 我再重複一遍，我們必須戰鬥！ 我們只有訴諸武力，只有求助於萬軍之主的上帝。

議長先生，他們說我們太弱小了，無法抵禦如此強大的敵人。 但是我們何時才能強大起來？ 是下週，還是明年？ 難道要等到我們被徹底解除武裝，家家戶戶都駐紮英國士兵的時候？ 難道我們猶豫遲疑、無所作為就能積聚起力量嗎？ 難道我們高枕而臥，抱著虛幻的希望，待到敵人捆住了我們的千腳，就能找到有效的御敵之策了嗎？ 先生們，只要我們能妥善地利用自然之神賜予我們的力量，我們就不弱小。 一旦300萬人民為了神聖的自由事業，在自己的國土上武裝起來，那麼任何敵人都無法戰勝我們，此外，我們並非孤軍作戰，公正的上帝主宰著各國的命運，他將號召朋友們為我們而戰，先生們，戰爭的勝利並非只屬於強者。 它將屬於那些機警、主動和勇敢的人們。 阿況我們已經別無選擇。 即使我們沒有骨氣，想退出戰鬥，也為時已晚。 退路已經切斷，除非甘受屈辱和奴役。 囚禁我們的咖鎖已經鑄成。 叮叮的鐐銬聲已經在波士頓草原上迴響。 戰爭已經無可避免——讓它來吧！ 我重複一遍，先生，讓它來吧！

企圖使事態得到緩和是徒勞的。 各位先生可以高喊：和平！ 和平！ 但根本不存在和平。 戰鬥實際上已經打響。 從北方刮來的風暴將把武器的鏗鏘迴響傳到我們耳中。 我們的弟兄已經奔赴戰場！ 我們為什麼還要站在這裡袖手旁觀呢？ 先生們想要做什麼？ 他們會得到什麼？ 難道生命就這麼可貴，和平就這麼甜蜜，竟值得以鐐銬和奴役作為代價？ 全能的上帝啊，制止他們這樣做吧！ 我不知道別人會如何行事；至於我，不自由，毋寧死!!

Give Me Liberty Or Give Me Death

No man thinks more highly than I do of the patriotism, as well as abilities, of the very worthy gentlemen who have just addressed the House. But different men often see the same subject in different lights; and, therefore, I hope it will not be thought disrespectful to those gentlemen if, entertaining as I do opinions of a character very opposite to theirs, I shall speak forth my sentiments freely and without reserve. This is no time for ceremony. The questing before the House is one of awful moment to this country. For my own part, I consider it as nothing less than a question of freedom or slavery; and in proportion to the magnitude of the subject ought to be the freedom of the debate. It is only in this way that we can hope to arrive at truth, and fulfill the great responsibility which we hold to God and our country. Should I keep back my opinions at such a time, through fear of giving offense , I should consider myself as guilty of treason towards my country, and of an act of disloyalty toward the Majesty of Heaven, which I revere above all earthly kings.

Mr. President, it is natural to man to indulge in the illusions of hope. We are apt to shut our eyes against a painful truth, and listen to the song of that siren till she transforms us into beasts. Is this the part of wise men, engaged in a great and arduous struggle for liberty? Are we disposed to be of the number of those who, having eyes, see not, and, having ears, hear not, the things which so nearly concern their temporal salvation? For my part, whatever anguish of spirit it may cost, I am willing to know the whole truth; to know the worst, and to provide for it.

I have but one lamp by which my feet are guided, and that is the lamp of experience. I know of no way of judging of the future but by the past. And judging by the past, I wish to know what there has been in the conduct of the British ministry for the last ten years to justify those hopes with which gentlemen have been pleased to solace themselves and the House. Is it that insidious smile with which our petition has been lately received? Trust it not, sir; it will prove a snare to your feet. Suffer not yourselves to be betrayed with a kiss. Ask yourselves how this gracious reception of our petition comports with those warlike preparations which cover our waters and darken our land. Are fleets and armies necessary to a work of love and reconciliation? Have we shown ourselves so unwilling to be reconciled that force must be called in to win back our love? Let us not deceive ourselves, sir. These are the implements of war and subjugation; the last arguments to which kings resort. I ask gentlemen, sir, what means this martial array, if its purpose be not to force us to submission? Can gentlemen assign any other possible motive for it? Has Great Britain any enemy , in this quarter of the world, to call for all this accumulation of navies and armies? No, sir, she has none. They are meant for us: they can be meant for no other.

They are sent over to bind and rivet upon us those chains which the British ministry have been so long forging. And what have we to oppose to them? Shall we try argument? Sir, we have been trying that for the last ten years. Have we anything new to offer upon the subject? Nothing. We have held the subject up in every light of which it is capable; but it has been all in vain. Shall we resort to entreaty and humble supplication? What terms shall we find which have not been already exhausted? Let us not, I beseech you, sir, deceive ourselves. Sir, we have done everything that could be done to avert the storm which is now coming on. We have petitioned; we have remonstrated; we have supplicated; we have prostrated ourselves before the throne, and have implored its interposition to arrest the tyrannical hands of the ministry and Parliament. Our petitions have been slighted; our remonstrances have produced additional violence and insult; our supplications have been disregarded; and we have been spurned, with contempt, from the foot of the throne! In vain, after these things, may we indulge the fond hope of peace and reconciliation. There is no longer any room for hope. If we wish to be free-- if we mean to preserve inviolate those inestimable privileges for which we have been so long contending--if we mean not basely to abandon the noble struggle in which we have been so long engaged, and which we have pledged ourselves never to abandon until the glorious object of our contest shall be obtained--we must fight! I repeat it, sir, we must fight! An appeal to arms and to the God of hosts is all that is left us!

They tell us, sir, that we are weak; unable to cope with so formidable an adversary. But when shall we be stronger? Will it be the next week, or the next year? Will it be when we are totally disarmed, and when a British guard shall be stationed in every house? Shall we gather strength by irresolution and inaction? Shall we acquire the means of effectual resistance by lying supinely on our backs and hugging the delusive phantom of hope, until our enemies shall have bound us hand and foot? Sir, we are not weak if we make a proper use of those means which the God of nature hath placed in our power. The millions of people, armed in the holy cause of liberty, and in such a country as that which we possess, are invincible by any force which our enemy can send against us. Besides, sir, we shall not fight our battles alone. There is a just God who presides over the destinies of nations, and who will raise up friends to fight our battles for us. The battle, sir, is not to the strong alone; it is to the vigilant, the active , the brave. Besides, sir, we have no election. If we were base enough to desire it, it is now too late to retire from the contest. There is no retreat but in submission and slavery! Our chains are forged! Their clanking may be heard on the plains of Boston! The war is inevitable--and let it come! I repeat it, sir, let it come.

It is in vain, sir, to extenuate the matter. Gentlemen may cry, Peace, Peace- - but there is no peace. The war is actually begun! The next gale that sweeps from the north will bring to our ears the clash of resounding arms! Our brethren are already in the field! Why stand we here idle? What is it that gentlemen wish? What would they have? Is life so dear, or peace so sweet, as to be purchased at the price of chains and slavery? Forbid it, Almighty God! I know not what course others may take; but as for me, give me liberty or give me death!

"never learn something not useful"

many poeple may ask such a question when they were in school, or when they were studying:

"is the cubic root useful?"

"is the log function useful?"

"what is the use of those?"

As a "angry" teacher, i will reply them like this:

"Are you useful? No, you are not useful now. you need your parents, you even cannot take care well yourself. you did not make any contribution to the society! so, you should die."

Well, you can see the point is about the time. many things are not useful when you learn it, but it does not mean it is not useful at all. you never know how and where you use it one day.

As a beinger, you have right to ask the question of useful, coz you know nothing about it and, i presume, you like to use what you learn. However, when you ask such a question, just because you want to escape from the learning of challege, then, it is no more about the usefulness of the thing, but the usefulness of yourselve.

they are not useful, as long as you are not useful.

a great people said," i never learn something not useful." he means, he can use everything his learned, and then make nothing not useful.

some guys may further say, "not everyone needs to be great". well if some "human" had this thinking, he is not human at all, "it" is a single cell organizm with "human body", i.e. it is a lower-life-form of alian, which can be wiped out from this earth without any complain.

pursue, you may fail

stay, you must fail

therefore, i still teach, coz i believe they may useful some day.

蘋論：參與 6.4與 7.1上街有甚麼關連？

延續 20萬人參與 6.4集會，泛民呼籲市民 7.1上街。

香港人不是沒有頭腦、呼籲一下就會行動的民粹主義分子。 7.1上街要有上街的理由。延續 6.4若是理由的話，也要看 6.4與 7.1有甚麼關連。
參與 6.4，香港市民的目標很單純，不管我們對中國的發展是否滿意，對中央實行一國兩制是否有信心，是否覺得中共近年的施政已有改善， 6.4始終是我們心裏面的傷痕，是無法忘記的回憶。中共一日不為 6.4的定性翻案，一日不向受難者致歉，我們也只好年年參與 6.4燭光集會，年年悼念死難者。這是香港市民的良知未泯的表現。但如果說 7.1為香港爭取民主，是可以達致中國民主的第一步，又或者說要香港有民主中國才會有，因而讓 6.4與 7.1接上關連的話，那麼爭取中國實現民主的理想，對香港人來說就比較遙遠了。
7.1上街的目標也應該很單純，針對特區政府成立的紀念日，我們上街是感到需要向特區政府嗆聲，向它抗議，在過去一年，特區政府的管治太爛了，太不像話了。這使特區政府民望不斷趨下。但曾特首和特區政府並沒有改善施政的意願和具體措施，反而一味緊抱中央大腿，向中央獻媚，他不再尋求市民支持，他違反諾言拖慢 2012年政制安排，拒絕為實現普選鋪路，只是尋求賦予他權力的中央撐腰。於是有曾特首關於 6.4的見利忘義的說詞，於是有警方在 6.4夜落閘阻市民進入維園，以及出現警方大幅縮小出席人數的揑造數字，而這種揑造又十分拙劣，前廉政專員任關佩英問，警方說的 62,800人，這 800人的零頭，是怎樣點算出來的？
精明的前高官，一針見血地指出「造假的笨拙」。
一年來的劣政，包括最被詬病的花大筆公帑私聘副局政助、曼谷派機、處理外傭稅等等都不用多說了。就以最近財爺派糖來說吧，當財爺在記者會被問及何以未有措施幫助三無人士（無領綜援、毋須繳稅、無物業的貧窮戶）時，財爺卻反問記者：「有沒有甚麼好建議？」
他的回答使人覺得他的薪俸是白領了。魯迅曾說：「廚師做出一味食品來，食客就要說話，或是好，或是歹……但是，倘若廚師對着客人道：『那麼，你去做一碗來給我吃吃看！』那卻未免可笑了。」
財爺的話，正反映他不知道自己的職責所在。而從曾特首及其他高官（包括副局政助）的表現，我們相信這不是財爺一時失言，而是整個政府高官的普遍意識。
再舉最近關於金管局總裁的聘任為例，明明內定人選陳德霖已呼之欲出，但特府還要假惺惺地設立三人遴選小組，而這小組的設立和人選卻沒有公佈。當被議員質問是否已內定陳德霖才堆砌遴選小組時，署理財政司司長陳家強只是不斷重複，財政司司長有權委任金融管理專員。
事實上沒有人質疑財爺的權力，只是質疑行使權力時是否有不可告人的一面。但高官的回答就只強調「有權」，顯然高官們認為權就是一切。

這是一個甚麼政府？是否一堆不知道職責所在、只知有權在手可以濫用的高官們的俱樂部？他們也許深知道，即使有普選授權也是八年後的事，而且也知道屆時中央仍會牢牢掌握主動權；他們也知道第二個管治班子已在運作，而特府則早已拜倒在第二個管治班子之下。民選既遠，傳媒又多自我審查，民意調查可以不當回事，向中央諂媚遂成為特府彎曲的脊樑。為甚麼關於 6.4曾特首會說出那樣偏離香港民意的話？為甚麼他還厚顏說代表整體香港人的意見？為甚麼警方關於 6.4夜有這麼拙劣的謊言？原因只有一個，就是特府不再堅守一國兩制、高度自治，不再顧惜香港民意，只是一味奉迎中央。隱藏的另一個管治班子，已漸凌駕於公開的這一個管治班子之上。
如果「曾蔭權不代表我」是市民踴躍參與 6.4的原因之一，那麼爭取一個「代表我」的政府就是 7.1上街的理由。這就是 6.4與 7.1的關連性，是市民需要在 7.1上街向特府嗆聲的原因。

Dirac

Dirac was not a talkative person and of a quite literal mind, to which numerous anecdotes testify. Here is an example. In a seminar someone asked a question: “Professor Dirac, I do not understand that equation.” Dirac did not answer, so the chairman intervened and asked Dirac if he would answer the
question. To which Dirac replied: “that was not a question, it was a statement."

is it refelcting, Dirac was not tring to make his students understood?

or, the student should point out whihc part his did not understand.

46封求情信

copy From 高慧然( Blog )

油麻地天主教小學男教師持續三年與十二歲女生非法性交逾 300次，導致女生懷孕後更帶她非法墮胎！如此斯文敗類，居然有人力撐，辯方呈上的求情信達 46封之多，求情者包括校長、校監、校職員、被告教過的舊生，及舊生的家長。
46封求情信說明了甚麼呢？

且讓我們看看報章披露的求情信內容，求情者一致盛讚被告是勞心勞力、有愛心及熱誠的傑出老師，努力發掘學生的數學天份，協助學生在奧數大賽中得獎，助學生順利升讀包括皇仁及聖保羅在內的名校。校監范神父相信被告本質不壞。校長張志鴻更表示原諒及支持被告。

我們看到一個荒謬的現象，這些求情者，上至校監校長，下至師生家長，沒有一個人站在受害者的角度想想她的感受，想想這場噩夢對她一生的影響。他們只有利益衡量，沒有是非論斷。一個老師，只要有助學校提高學生升讀名校的比例，就是個本質不壞的好老師，就值得原諒及支持，就可以成為學生偶像。難怪煲呔敢大聲發表代表論，看來他決非自作多情，為了利益出賣良知，或者為了利益蒙蔽良知的人，舉目皆是。

油天是名校，這就是香港人的名校！注重，甚至可以說是只重利益教育，無視道德良知，由校職員工到學生家長價值觀畸形而一致，以利益論成敗，有利於我的，便是好人便是好事。我們的下一代，去哪兒尋找安全而健康的學校？

New service for banking

Many companies fix the salary account, which is different form empolyee's account, different bank.

So, this may cause lose of customer for bank, or a development barrier.

I suggest a new service:
For simplicity, let assume there are two banks, S and E, they are the banks hold the accounts for salary and empolyee. Now, the bank E opens an account at bank S for the customer, so, the customer dont need to take care for that account, since the account is belong to bank E, a kind of virtual account. And the customer only need to give that account back to his company.

Every month, the company gives salary to the virtual account in bank S, which is holding by bank E, then, bank E will automatically transfer those salary back to the customer account in bank E.

In the whole process, the bank E is the money holder, it can keep his customer from evacuate. And the whole process can be programed and minimized the cost.

Symmetry

When talk about symmetry, most people will think about mirror. Yes, it is a kind of symmetry for mirror image, but there are a lot more. In fact, I found that our students’ quality is so low that, they cannot be excited by unexpected things. In primary 1 or 2, we already exposed by many kind of symmetry form rotation, translation, and reflection. How come no one can remember? When I was small, I only knew the reflection symmetry. After I learned rotation and translation, this concept is printed so dark in my mind, because of unexpected.

Anyway, back to our topic. As I mentioned above, there are rotation and translation symmetry as well. For seeing why rotation can be called symmetric, we can use 2 mirrors, making an angle with each other, and then we can product “angle reflection”. For example, making the angle between the 2 mirrors be 90 degrees, we are producing a 90 degrees rotation symmetry, because the graph is “repeating” itself for every 90 degrees rotation. Moreover, because the graph repeats by 4 times, we called it as 4-fold symmetry. When we make the 2 mirror at 60 degrees apart, then we are making 6-fold symmetry. If we accept the mirror reflection is symmetry, then we must accept rotation is also symmetry.

How about Translation symmetry? Can translation symmetry be produced by mirrors? Yes, it can. If we have 3 equal mirrors, we can make a kaleidoscope. In the kaleidoscope, beside the images in the 3 corners, we can also see a repeating pattern extended to the whole space!

From above, we can see a very important concept of symmetry – repeat. More precisely, repeated after certain transform. For reflection, the pattern repeated after a reflection (reflection is a kind of transform). Patterns repeated after rotation, after translation.  

Now, we are standing on a point for a conceptual jump. If something unchanged (repeat) from time to time, then we called it has symmetry over time. Let’s take examples, you weak up every morning at 8am, then that action is translation symmetry over time. We play a movie clip and then reverse play, and then it is reflection symmetry over time. In fact, many things have translation symmetry over time. However, if you have a clock, but after a while it broken, than the clock has symmetry breaking. It is no longer symmetry over time. Therefore, in fact, we have a lot of thing has short term symmetry and only few things have truly symmetry over time.

The physical laws and constants are the only things have forever symmetry over time. 

Can any one see now? the law of conservation of momentum and energy is just from the symmetry. From a lot experience, we believe our univerise is governed by a set of symmetry law.

for a deep understanding of symmetry, reader should study the Group theory. Group means, inside a group, every memeber share the same symmetry porperties.  

the 7 points

4月17日，學生開始聚集在天安門廣場。當天下午，第一支遊行隊伍、中國政法大學法律系約500名學生在人民大會堂東門舉行悼念活動，過程中警察未能驅散群眾，當晚廣場上已經聚集上千人，除了政法大學學生外，還有其他高校學生和普通市民增援。翌日凌晨，約3,000人學生從北京大學前往天安門，沿途近千名清華大學學生加入。清晨，數百名學生在人民大會堂前靜坐，要求人大常委接見，並向常委提交請願信，提出7點要求：

一，重新評價胡耀邦同志的是非功過，肯定其民主、自由、寬鬆、和諧的觀點；

二，徹底否定清除精神污染和反對資產階級自由化，對蒙受不白之冤的知識分子給予平反；

三，國家領導人及其家屬年薪及一切形式的收入向人民公開，反對貪官污吏；

四，允許民間辦報，解除報禁，實行言論自由；

五，增加教育經費，提高知識分子待遇；

六，取消北京市政府制定的關於遊行示威的「十條」規定；

七，要求政府領導人就政府失誤向全國人民作出公開檢討，並通過民主形式對部份領導實行改選。

It's only love

※如果只有一個願望能實現
那麼就讓我在你身邊恬睡 哪里也不想去
Beautiful world
凝視著堅定的你
Beautiful boy
還不知道自己的美嗎※

It's only love

睡著醒著 都只夢見少男漫畫
難道他就不喜歡我嗎

他想要什麼 我不知道
只想要臉頰上流淌著的溫存的淚

什麼都不想說
只想再見一次面
想說的事情卻不能說
說不定是沒有毅力
雖然這樣也不錯

（※反覆）

It's only love

什麼事情都試著做做看
雖然這樣的結果是吃虧　但卻能從中汲取經驗

根本不需要什麼報紙
連那麼重要的事情都沒有記載
最近的氣氛是怎麼了
如果還充滿幹勁的話
那也還好吧

如果我的世界消失那天能夠遇見你
在你的身邊恬睡 　無論在什麼樣的地方
Beautiful world　
在過度虛幻的每一天裏
Beautiful boy
世外桃源不是辦法

如果只有一個願望能實現
那麼就讓我在你身邊恬睡

Beautiful world...

宜 / 忌

1. 宜：講八卦youtube短片，例如機場阿嬸、明愛小童群揪會等等，大家都有睇過，或者未睇都會追返的無聊東西。

2. 忌：講專門術語，例如「派膠」、「女體化」、「女僕控」之類需要較專門背景才聽得懂的詞彙。

3. 宜：講電影、電視劇或漫畫。通常電影的觀眾最多，電視劇次之，漫畫又其再次。總之找一些大家共同經歷過或感興趣的話題講，百搭是星相命理玄幻鬼怪宗教，總會中一項。

4. 忌：跳step講野，即是假設對方已完全明白對話的背景和前設，一般在動漫電玩(ACG)宅族比較嚴重，ACG宅男們可以突然講某本漫畫第20期某情節很好笑。假如你未看過這20期漫畫是完全無法溝通的。這亦可解釋為何ACG宅族在一般社交場合跟其他人的兼容性較低。

5. 宜：用貼近生活的方法講解技術性的東西，有時總無可避免要解釋自己的工作。記得朋友的工作是「優化人工智能編程」(ai optimization?)，當時他問黑人懂不懂perl、OOP等基本常識(用以判斷講多少給黑人聽)，自問略懂皮毛中的皮毛，聽了一會，大概可以超粗略地解釋為「假如桌面有杯咖啡，我想指示電腦去『飲咖啡』，我的工作就是教曉電腦自行判斷到底伸個頭埋去飲、伸手拿起個杯飲、還是用飲筒飲比較有效率。」

對一般layman來說，上述解釋應該足以令他們清楚明白閣下的工作，再加以十二分欽佩。謙虛點的，可以補充：「現在的電腦連『飲』和『咖啡』都未懂，單這一環就要十年，我希望有生之年會有丁點成果啦！」

(某失控中女：「嘩！好叻啊！田田！田田！」)

6. 忌：怕羞。極真流空手道注重挨打抗擊訓練，用意消除人害怕挨打的本能：實戰中不怕死爛命一條的人最可怕。

同樣，社交場合一般人最怕就是出醜，假如細心思考出醜的後果，又可能沒有想象般嚴重：講了個爛gag無人接被人反反白眼而已。以前黑人很怕被人笑被傳通街。但實情是，你有幾把炮？值得人地日提夜提記住你？面皮厚不是無敵，但絕對會佔優。最壞的下場是被對方不點名在blog講下你，邊個知？甚至有時被人唱都不一定是壞事，例如葉一知在節目中提及的$63.8事件，大家就同情被唱那一位。

7. 宜：基本儀容。黑人很遲才知道這一點重要，識著衫絕對有優勢，如不懂搭配衣裝，基本無穿無爛已ok，其次是無頭皮口氣體味等非常基本的衛生儀容。

8. 宜：活躍，主動撩女仔。所謂「男人不壞女人不愛」也。香港才子蕭若元解釋這句話背後有遺傳學的大智慧：壞男人四處留種，較易延續基因，生出來的下一代亦會遺傳到同樣的性格。可是現代社會男女需合力經營家庭，所以女人又希望拍拖或結婚後壞男人「從良」。非常矛盾，歷來亦有不少女人屢戰屢敗。

蕭才子又謂，大多數女人雖然根據這套遺傳智慧擇偶，但本身並不知情，口中說想找個好男人(後天理性需要)，轉眼又重投壞男人懷抱(遺傳上的本能)。

所以，一般好仔宅男不須花氣力將自己完全改造成壞男人，只須瞞過這套篩選機制，得米後回復本性便可。(到時女朋友呻你悶又點？賺左啦已經。)

9. 宜：較長遠的，最好梗係有返d興趣，試下聽不同的音樂、書籍、電影等等。香港人工作效率第一，生活情趣是世界倒數頭幾位，因為香港人情感相當平板，看看日常形容心情的詞彙可知一二：「勁搞笑」，「灰到爆」。

10. 宜：建立自信。最直接的方法是高收入，但大多數人都難以憑這個法子增強自信。另一個辦法是靚仔，都不是人人做得到。最後人人可做的方法是做些令自己有成就感的事，最好當然是做運動，常做運動體能又較好的人肢體語言跟普通人有明顯分別(長年練功夫就更加覺)。打機叻或者砌電路板好勁都得，但係較少人欣賞囉。

On Talents and Recruitment

This is to Tim, as i promised, and as he said, i should blog it out in case i will forget. :P

on a company, Talents not only count for the employee, but also employer. both of their ability should be match in order to making the company growth smoothly. just like our 2 legs, should be same long. However, employer should have something more: he is the one who lead the company direction. if a weak employer, i don't suggest he should hire someone more talent. well, not everyone able to be the leader.

so, the first thing is to understand yourself. what kind of personal you are? what is the advantage in your personality, attitude and ability? Can you be a standard for your staffs?  what is your goal on the company? 

the 2nd thing to consider for recruitment is: (1)whether you want to hire someone already good to use, or (2) someone has great potential to be modified. 

i will only talk about case (2). because case one may be another thing.

1. able to take responsibility when he fail -- many people, especially, Chinese, are afraid to admit his failure and find excuses. that is really bad for a team. we can set an imaginary situation when interview potential employees to test this.
   
2. don't afraid to argue, or give ideas or suggestion - this is so called insist when you have the truth. if a person will easily change his mind under public pressure. i will regard he is useless in 3 points. 1) he don't believe himself. 2) he don't like to argue, and may be regarded argue is bad. 3) he don't have guts, may be his metal age is too old. 
   
3. don't afraid to ask - since not one can be the "known it all". however, if someone always ask without find the answer by himself in advance, then he is just an question box. 
   
4. ambition, but don't be too much that without working plan or solid foundation - ambition is the engine of all company. 
   
5. care about foundation of knowledge - (i believe) people care about that must have his point of view, a person with idea, knowing the power of knowledge. if he know the power of knowledge, than he must understand the power of rational thinking. if he know the power of rational thinking, then he must be independent, because he can always rely on his knowledge. you know, it means everything!
   
6. when his idea conflict with ration thinking and experiment, he don't afraid to change his mind and accept the failure. -- that is related to the point (1)
7. Moral, ability to control himself to do something wrong. - that is a hard aspect to see. using imaginary situation can possible reveal that. like some "cross-road of life" cases. this also can see whether his idea match with you. the conflict of family and office matters.
8. how many steps he can foresee for his action - this not only test his general ability but also imagination and creative. some people can have fancy imagination but that is far form real world. just like a good chess player, the more step he can see, the more advantage he has. another reason for this is - can he think of the other? to have "public moral" (公德). you know, if you work in a team, what will happen if someone only think about himself.

well, it seem that it is hard to found someone fulfill all these :P more like a principle for advanced man. anyway, don't believe me, use yourself adjustment. don't forget that i know nothing about this world, but just a bit of physics.

Knowledge Horizon

in medieval world, people believe earth is flat. because they lack of knowledge. 

lets make an analogy between earth and knowledge.

on earth, it has surface. some filled wih lands, some filled with water. human, may like to divid the land by boundary, and call each area in term of nation. A more natural division may be the heritages, like ice land, tropical, dessert, etc.

on knowledge, it has a lot of subjects, like physics, arts, Psychology, politics, biology, etc. but these are the man made boundaries. in reality, we can see the boundary of different subjects is hard to distinguish, just like the boundary of tropical and dessert. 

if our understanding of knowledge reached certain level, we can see our knowledge system form a globe. there is one and only 1 knowledge, but different aspects of it. 

that's why, when we study at some level. we will entitled Doctor of Philosophy. because there is only 1 knowledge.

and human is now working on the discovery of different landscape of the knowledge globe. 

Black and White

Many people believe a lot of things are gray, hard to tell it is correct or wrong. 

i agree. however, i believe, these world consists with a lot basic stuff, and each, is either Black or White, Right or Wrong.

imagine, we are in Africa, watching a group of Zebras. From long distance view, you can only see gray in color. however, if you use a telescope, you will see, only black and white.

so, things are gray, because people don't want to, or not able to inspect every little detail. 

1, don't want to:

i will regard this kind of people are low-grade human. they are not evolute.  

2, not able to :

that's why we need education.

currency exchange

i have 22000 JPN after Japan Trip. the rate is now 1000 JPN to 8.3HKD. 

the clerk tell  me it is around 2000HKD, need to pay 50HKD as a fee. but she also tell me, if i have other currency more than 3000HKD in total, then free of charge.

i ask her.

can i use 3000HKD to RMB, than change those RMB and JPN to HKD?

currently, 

3000HKD -> 2,646.0553 RMB

22000JPN  -> 1,915.78 HKD

2646 RMB  -> 2999.99 HKD

and 2646.05 RMB + 22000JPN  -> 4,915.77 HKD

therefore, i don't need to pay any fee!!!

i am so suprised that i suddenly come up with this trick. :P

in this way, let us calculate how much money exhange will really cost some fee.

Let 
R(HKD, RMB) be  rate from HKD to RMB
RMB = R(HKD,RMB) HKD..........(1)
R(RMB,HKD) be the rate from HKD to RMB
HKD = R(RMB, HKD) RMB.........(2)

this 2 rate should be only different by some among : d 

R(HKD,RMB)* R(RMB,HKD)  + d = 1
d can be positive or negative. 

the lost is 
 HKD -  R(RMB, HKD) R(HKD,RMB) HKD =  d * HKD

currently, the d is less than 0.0001 therefore, if i exchange more than 
 d * HKD >= 50

=> HKD > 500,000 at least (apprx.)

, then i have to pay 50HKD fee for the exchange. 

however, if i exhange more than 3000HKD, i don't have to pay. 
therefore, we never need to pay. 

i suggest, if the bank really like to charge some fee, 

they need to set each exhange will be free for more than 500,000 HKD.

if so, no body can play trick. 

but all about only for d is positive. 

if d is negative, i really earn money from this exchange!

may be, just forget the fee.
