香港譯名:

1998 《Following》

2000 《凶心人》

取「空心人」同音。「心」,是指「記憶」。所以,電影譯名的意思是,沒有記憶的人。

2002 《白夜追兇》

2005 《俠影之謎》

2006 《死亡魔法》

此電影的主題為魔術,所以導演把電影本身,化成一個魔術。

2008 《黑夜之神》

2010 《潛行凶間》

此電影的主題為夢境,所以導演把電影本身,化成一個夢境。

2012 《夜神起義》

2014 《星際啓示錄》

「啓示」,即是「來自未來的訊息」。

2017 《鄧寇克大行動》

2020 《天能》

A lot of Nolan’s movies are about some kinds of time travel.

For those movies, each has a unique time logic. Each is like a stage of the computer game Braid.

In Braid, there are 6 stages. Each stage has a unique time mechanics.

太極滅世戰 2.1

似水流年 2.2

.

還記得童年時不太開心,好像沒有太多事情,令我快樂。換句話說,即是過得沉悶。一方面喜歡讀書,另一方面卻緊張成績,終日惶恐。

近乎唯一娛樂就是看電視。那時,我還沒有電腦,更加沒有互聯網。那時,沒有什麼金錢買玩具。就算有新玩具,我有時會想:「怎麼辦呢? 很快又會厭倦。」

中二開始,發覺對數學幾有興趣。

中途又有些所謂的嗜好,例如集郵,其實沒有意義。相對沒有那麼無聊的,有電腦遊戲。我的摯愛有 Simcity 2000 和 Chrono Trigger 等。但那也只是暫時的快樂,仍未能為我生活,帶來意義;遊戲完結時,感到額外的空虛。

中四上物理時,不知何故,精神上,有一點清涼暢快的感覺。那就代表著,疑似喜歡物理。但是,不知何故,幾乎凡是需要物理思考的題目,我都不懂得做。

一九九六年,逛書店時,看到有一本書叫《時間簡史》。我同學說:「這書(內容)就是你最喜愛的那些東西。」那時,我尚未有觸動心靈的感覺,所以不以為意,沒有購買。

那年暑假,看了香港太空館天象廳的《輪椅中的宇宙》,十分震撼。我大概記得,那是我自己一個去看,沒有朋友一起。

dsc025651

從紀錄片中,我認識了霍金,知道了《時間簡史》的來源。不久之後,我買了《時間簡史》,企圖一口氣讀完它。過程中,我有惶恐不安的感覺。原因不是書中內容,而是我沒有閱讀的習慣。換句話說,《時間簡史》令我開始了,培養閱讀的習慣。

《輪椅中的宇宙》和《時間簡史》令我發現,我的人生目標是物理。

但是,我自中三開始,那些物理題目,真是不太懂做呀。空有目標,沒有執行之道。

其實,我那時沒有也辦法,因為,我日校物理教師,講物理講得十分有趣,而我又有留心聽講。如果在這個情況下,我仍然不懂的話,那大概是我的智力問題。

幸好,後來發現,那不是事實。至起碼,中五會考物理,並不需要高智力,也可以奪得 A 級成績。十多年後,在自己有足夠的讀書和教學經驗後,我發現,我當年不懂做題目,主因是日校物理教師,只談理論,不會教題目細節。甚至,有些課題,例如電學,連他自己也根本不太認識。

一九九六年的那個暑假,我開始參加 Ken Chan 的物理補習班,開始一步一步的,解決了「空有目標,沒有執行之道」這問題。

有了「做物理學家」這長遠目標後,我感到人生不再一樣,雖然,我讀書的日常生活,仍然十分混亂,

Simcity, 2

d_2019_12_29__15_35_29_PM_

I bought this SimCity 2000 box in 1995. It was the first time I went to a big computer centre (mall).

At the first glance, I thought that it was sold at the price 800 HKD, which I could not afford. Luckily, the price label was actually NT800, which meant 800 New Taiwan Dollars.

So I could buy it at 200 Hong Kong Dollars.

Pandemonium

E: Can you just, you know, like, just tell me the answer?

J: Sorry?

E: You know, the answer. To everything.

What’s the point of love if it’s just disappear?

There has to be meaning to existence, otherwise the universe is made of pain and I don’t like the thought of that.

So, tell me the answer!

J: The more human I become, the less things make sense.

But that’s part of the fun. Right?

E: What do you mean?

J: If there were an answer I can give you to, how the universe works, it wouldn’t be special. It would be just a machinery fulfilling its cosmic design. It would be just a big, dumb food processor.

But, since nothing seems to make sense, when you find something or someone that does, it’s euphoria.

.

In all of this randomness, in this pandemonium, you and Chidi found each other and you had a life together.

Isn’t that remarkable?

E: Pandemonium is from Paradise Lost. Milton called the center of hell “pandemonium”, meaning “place of all demons”.

I guess all I can do is to embrace the Pandemonium.

Find happiness in the unique insanity of being here, now.

潛行凶間 16.3

Inception 16.3

這段改編自 2010 年 8 月 13 日的對話。

.

怎料,當早所看的電影《潛行凶間》那麼應景,恰巧在主題中有「清醒夢」和「多層夢」。那就是為什麼我剛才說:

《潛行凶間》中的意念,你可以假想,有七成是真的。

知道這些有趣知識——原來世間上,是有「清醒夢」和「多層夢」——是有實質好處的。

例如,你會繼而知道,原來人是有「潛意識」的;而在一些清況下,「潛意識」的智力和能力,多過「顯意識」。但是,「潛潛意識」又再利害過「潛意識」。

再例如:

3. 多重自我

3.1 每一個人,其實有超過一個自我。

3.2 而每一個自我,其實有超過一個層次的意識。

至於在平日,怎樣可以存取到,各個層次的潛意識呢?

有太多的方法,有些是健康的,有些是自殘的,不能盡錄。現在只講一兩點。

健康的方法有,適量的睡眠。睡眠太多或太少,都到身體、顯意識和潛意識有害。睡眠太少的話,你的潛意識,沒有足夠時間,去整理日間接收了的資料。

自殘的方法有,患病。

.

「清醒夢」或「多層夢」,如果自然發生,你可以細心觀察。

但是,千萬不要主動去引發「清醒夢」或「多層夢」。它們時常發生的話,會破壞意識,脫離現實。

33 INT. HOLDING AREA

Quark and Sakonna are sharing the same cell.

QUARK
I hope you’re happy.

SAKONNA
I am a Vulcan. My emotional state is irrelevant.

QUARK
Well I’m a Ferengi. And my emotional state is very relevant. And right now, I’m miserable. And it’s all your fault.

SAKONNA
You were well paid for your assistance.

QUARK
Not well enough. Look, why don’t you just tell them what they want to know?

Sakonna just stares at him.

DEEP SPACE: “The Maquis, II” – 02/17/94 – ACT FOUR 42.

33 CONTINUED:

QUARK
(continuing, talking confidentially) I know the Cardassians can’t be trusted. I know that the Central Command would like nothing better than to destroy the Federation colonies in the Demilitarized Zone.

SAKONNA
Then you agree with our position?

QUARK
Not for a second.

SAKONNA
Why not?

QUARK
Because your position is… (searching for the right word) Illogical.

This takes Sakonna off guard.

SAKONNA
Do you propose to lecture me on logic?

QUARK
I don’t want to, but you leave me no choice. It all comes down to the third Rule of Acquisition.

(off her blank reaction)

You don’t know that one, do you?

SAKONNA
I am not well versed in Ferengi philosophy.

QUARK
Remind me to get you a copy of the Rules. You never know when they’ll come in handy. Now, the third rule clearly states,

Never pay more for an acquisition than you have to.

SAKONNA
Logical. But I fail to see how that applies to my situation.

DEEP SPACE: “The Maquis, II” – 02/17/94 – ACT FOUR 43.

33 CONTINUED: (2)

QUARK
You want to acquire peace. Fine.

Peace is good. But how much are you
willing to pay for it?

SAKONNA
Whatever it costs.

QUARK
That’s the kind of irresponsible spending that causes so many business ventures to fail.

You’re forgetting the third rule. Right now peace could be bought at a bargain price and you don’t even realize it.

SAKONNA
I find this very confusing.

QUARK
Then I’ll make it so simple that even a Vulcan can understand. The Central Command has been caught red-handed smuggling weapons to their settlers. So from now on, every ship approaching the Demilitarized Zone will be searched. Without the support of the Central Command, the Cardassian settlers won’t be so eager to fight.

SAKONNA
You forget the weapons they already have.

QUARK
They have weapons… you have weapons… everyone has weapons. But right now, no one has a clear advantage. So the price of peace is at an all-time low. This is the perfect time to sit down and hammer out an agreement. Don’t you get it… attacking the Cardassians now will only escalate the conflict and make peace more expensive in the long run. Now I ask you, is that logical?

Quark sits down, pleased with his performance.

又例如:

2. 多層夢

有時,明明已經起了床,關掉了鬧鐘;怎料,「明明已經起了床,關掉了鬧鐘」這劇情,只是另一個夢——我仍然未醒來。結果,要醒了很多次,經歷很多層,才真正醒來。

而對我個人而言,最有趣的地方是,我在看《潛行凶間》之前一晚,正正發了「清醒夢」和「多層夢」。

我在看《潛行凶間》前的那個時期,身體長期不太舒服,可能是傷風或者感冒,導致有少許咳嗽。但是,在戲院內咳喇的話,會影響他人,所以可免則免。因此,在前一晚,因為知道明早要去看電影,我的潛意識對身體下令,要立即康復。那樣,一來令我腦部活躍,二來令我身體病發,引發了我的「清醒多層夢」。

怎料,當早所看的電影《潛行凶間》那麼應景,恰巧在主題中有「清醒夢」和「多層夢」。那就是為什麼我剛才說:

《潛行凶間》中的意念,你可以假想,有七成是真的。

On Lisp

paulgraham_2202_3475946

Lisp is an especially good language for writing extensible programs because it is itself an extensible program.

Because Lisp gives you the freedom to define your own operators, you can mold it into just the language you need. If you’re writing a text-editor, you can turn Lisp into a language for writing text-editors. If you’re writing a CAD program, you can turn Lisp into a language for writing CAD programs. And if you’re not sure yet what kind of program you’re writing, it’s a safe bet to write it in Lisp. Whatever kind of program yours turns out to be, Lisp will, during the writing of it, have evolved into a language for writing that kind of program.

潛行凶間 16

Inception 16

這段改編自 2010 年 8 月 13 日的對話。

d_2018_02_18__19_10_12_PM_

這幾個月來,我跟一位來自大學時代的朋友,討論一些較為深刻精采,一般人也不會討論的話題。怎料,《潛行凶間》竟然囊括那些深刻精采話題,之中的一大部分。

在我朋友的同意和鼓勵下,我把那些對話錄了音,再化成文字。那就彷彿是把那些意念,由氣體凝結成液體。怎料,該電影卻把那些意念,再由液體凝固成固體。

我把對話化成文字,莫非都是為了避免,同一堆說話,再講一次。同一堆說話講第二次,並不是一個快樂的過程。有了文字版後,當有其他朋友需要那些意念時,我就可以引述我的文章,從而開發下一個層次的話題。

但是,有了《潛行凶間》這電影後,凡是之中有的意念,我的相關文章,都可以一概置之不理;因為,我只要介紹該電影,給對那些意念,有興趣的朋友就可以。

電影內,有太多超凡的意念,不能一次過講得完。你們可以分開幾次來問我,例如:

1. 清醒夢

1.1 有些人在某些時候,在夢知道自己在發夢,卻又可以保持住,發夢的狀態。

1.2 那些人之中的部分人,在那些清醒夢時候的部分時候,甚至可以控制著,那些夢境的劇情演變。

你有沒有試過,在夢裡面,知道自己在發夢?

(CPK:未。不過,我的姐姐試過。)

我中學時代,有一次清醒夢時,刻意留意一棵樹。

我發現,原來夢中的東西,不只有黑白色。我不單看到,那棵樹的葉是綠色的,而且,還可以見到,那些樹葉中的每一塊。

《潛行凶間》中的意念,你可以假想,有七成是真的。

又例如:

2. 多層夢

有時,明明已經起了床,關掉了鬧鐘;怎料,「明明已經起了床,關掉了鬧鐘」這劇情,只是另一個夢 — 我仍然未醒來。

3. 多重自我

3.1 每一個人,其實有超過一個自我。

3.2 而每一個自我,其實有超過一個層次的意識。

Intellectual Headaches

Game design

They got the key, and then some other stuff happened, and then they reached the door, and were able to open it; but “acquiring the key” and “opening the door” were stored as two separate, disconnected events in the player’s mind.

If the player had encountered the locked door first, tried to open it, been unable to, and then found the key and used it to open the door, the causal link would be unmistakable. You use the key to open the locked door, because you can’t open the locked door without the key.

Math education

I’ve drawn parallels between game design and education before, but it still took me a while to realize that problem-solution ordering issues crop up just as often in the classroom as they do in games.

Remember how, in high school math class, a lot of the work you were doing felt really, really pointless?

Consider Dan Meyer’s question for math educators: if math is the aspirin, then how do you create the headache?

In other words: if you introduce the solution (in this case, a new kind of math) before introducing the kind of problems that it’s meant to solve, the solution is likely to come across as pointless and arbitrary. But if you first let students try to tackle these problems with the math they already understand, they’re likely to come away with a kind of intellectual “headache” – and, therefore, to better understand the purpose of the “aspirin” you’re trying to sell.

. . . it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. Its peculiar character, too, is that no one possesses the less, because every other possesses the whole of it. He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me.

That ideas should freely spread from one to another over the globe, for the moral and mutual instruction of man, and improvement of his condition, seems to have been peculiarly and benevolently designed by nature, …
