Single-world interpretation, 6.5

Posted on February 25, 2012 by rpflee

If this is the case, then wave function is deterministic. There is no free will. The free will is due to the ongoing superposition of eigenstates. Locally, we see superposition of “a and b” collapse to (such as) a. Globally, we also see b “goes to” the environment. Nothing is lost in a sense that no information is lost.

Then what happens when you make a choice by collapsing a wave function?

Free will, like wave function collapse, is a local illusion.

Since information cannot be lost, we always exist.

Assume that there are two choices: path a and path b.

If my path is a, my b-path self is encoded in a-path’s environment through quantum entanglement, vice versa.

Posted on February 22, 2012 by rpflee

In the Many-worlds interpretation (MWI), when we say that “a + b” collapses to “a”, there is a shift of definition of “you”.

MWI is in one sense correct: choice b version of you still exists. But the trick is that he is not in another universe. He is in the environment of this universe.

And perhaps in reverse, you are also part of the environment of him.

這段改編自 2010 年 3 月 20 日的對話。

Every lecture should make only one main point.

The German philosopher G. W. F. Hegel wrote that any philosopher who uses the word “and” too often cannot be a good philosopher. I think he was right, at least insofar as lecturing goes. Every lecture should state one main point and repeat it over and over, like a theme with variations.

— Advice for the Young Scientist

— John Baez

與志同道合的人傾談時，我會在電光火石之間，同時爆發很多條思考線出來，令我「驚惶失措」，不知先講哪一樣比較好。

寫作時會有類似的問題。所以，我迫自己每日最多只寫一篇文章，而文章每篇最多只可以有一個（主要）新點子。那對我來說，有穩定思想、克制情緒的作用。

另外，寫作太多，其實沒有什麼大意思。一來，自己不會有那麼多的時間。二來，讀者亦不會全部閱讀。即使全部閱讀，他們也不會有足夠時間，去把學到的道理付諸實行。「道理」即是「方法」。方法，是用來解決問題的。不能實行，或者不實行的道理，是廢話廢字，不寫也罷。

寫一句讀者會確切執行的東西，勝過寫十篇看過就算的文章。真正重要的，不是我寫了什麼，而是讀者看到什麼、想到什麼和做到什麼。

本質先於存在

我在買零件組裝電腦前，心目中，會對那部電腦的性能有所要求，例如它的運算速度有多高。換句話說，那部電腦在存在之前，就已經擁有自己的性質。那就為之「本質先於存在」。

— Me@2012.02.06

存在先於本質

其最著名和最明確的倡議，是沙特的格言：「存在先於本質」。他的意思是，除了人的生存之外，並沒有天經地義的道德或靈魂。道德和靈魂，都是人在生存中創造出來的。人沒有義務遵守，某個道德標準或宗教信仰，卻有選擇的自由。要評價一個人，就要評價他的所作所為，而不是評價他是個什麼人物，因為一個人，是由他的行動來定義的。

Process, not a state, 4

Posted on February 4, 2012 by rpflee

Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit.

— Aristotle (384 BC – 322 BC) Greek Philosopher

* Source: Will Durant, _The Story of Philosophy: The Lives and Opinions of the World’s Greatest Philosophers_ (1926) [Simon & Schuster/Pocket Books, 1991, ISBN 0-671-73916-6] Ch. II: Aristotle and Greek Science; part VII: Ethics and the Nature of Happiness:

    “Excellence is an art won by training and habituation: we do not act rightly because we have virtue or excellence, but we rather have these because we have acted rightly; ‘these virtues are formed in man by his doing the actions’; we are what we repeatedly do. Excellence, then, is not an act but a habit: ‘the good of man is a working of the soul in the way of excellence in a complete life… for as it is not one swallow or one fine day that makes a spring, so it is not one day or a short time that makes a man blessed and happy‘” (p. 76).

    The quoted phrases within the quotation are from the Nicomachean Ethics, Book II, 4; Book I, 7. The misattribution is from taking Durant’s summation of Aristotle’s ideas as being the words of Aristotle himself.

— Wikiquote

Excellence is a process, not a state, nor an event.

An event is a change of state. A process is an infinite chain of events.

Memory loss

Posted on November 26, 2011 by rpflee

BBC Brain Story, 2

… and I’d go on to explain that much of what we take to be memory loss has other explanations.

For instance, as our values change with age, we often don’t care about certain things to the degree we used to, and we therefore don’t pay much attention to them anymore. The “memory problems” of the elderly are often simply due to the fact that they haven’t noted something that they find rather uninteresting.

Delayed choice quantum eraser

Posted on November 20, 2011 by rpflee

Quantum decoherence 5.2 | Event Realism 5 | 事件實在論 5

For a delayed choice quantum eraser, both interference patterns are there.

But since they overlap each other, you cannot see them individually.

— Me@2011.10.21

One of the easiest ways of “making sense” of the delayed-choice paradox is to examine it using Bohmian mechanics. The surprising implications of the original delayed-choice experiment led Wheeler to the conclusion that “no phenomenon is a phenomenon until it is an observed phenomenon”, which is a very radical position. Wheeler famously said that the “past has no existence except as recorded in the present“, and that the Universe does not “exist, out there independent of all acts of observation”.

What we do in the present does not change the past, but change we can see/say about the past.

The delusion

Posted on November 15, 2011 by rpflee

The most powerful illusion, 2

February 12, 1950

Dear Mr. Marcus:

A human being is a part of the whole, called by us “Universe”, a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest — a kind of optical delusion of his consciousness. The striving to free oneself from this delusion is the one issue of true religion. Not to nourish the delusion but to try to overcome it is the way to reach the attainable measure of peace of mind.

With my best wishes,
sincerely yours,

Albert Einstein.

金錢管理

時間管理 5.3

這段改編自 2010 年 3 月 6 日的對話。

所謂「時間管理」，就是用「時間」這個參數，去研究「人生問題」。另外一些作家，會在他們的書籍或者網誌上，寫以「財政管理」為主題的文章。慢慢你會發現，那些「財政管理」文章的結論，往往同「時間管理」的道理共通。其實，那就即是用另一個參數 —— 金錢 —— 去觀察「人生問題」。

（安：我見過有些書籍，是以「精神狀態管理」的角度出發。）

那就即是以「健康」這個參數，去思考「人生問題」。不喜歡用「時間」、「金錢」、「健康」作參數的話，你亦可以轉用「智力」、「情緒」和「體重」等等。可供選用的參數多不勝數。

百慮而一致，殊途而同歸。例如，你可以將「時間管理」的道理，翻譯成「財政管理」的道理，反之亦然。

（安：你肯定？）

細節未必，但大方向就可以。只要是大道理，無論是「時間大道理」，還是「金錢大道理」，總可以翻譯「人生大道理」。

（安：另一個可能性是，把「時間管理」和「財政管理」，都看成「工作效率」的課題。）

那和我的意思一樣。

嚴格來說，「時間管理」和「財政管理」並不是兩樣共通的東西，而是同一樣東西 —— 人生問題 —— 的兩個不同角度。我剛巧對「時間」特別有興趣，所以特別研究「時間管理」。但是，你沒有必要跟隨，因為你最有興趣的課題，可能是（例如）「金錢」。那你就應該詳細研究「財政管理」。

你要人生過得快樂，未必有需要對所有課題都博覽群書。只要選定你最喜歡的一個課題，詳細研究和應用就可以。

Twelve Monkeys

Posted on October 20, 2011 by rpflee

Themes

Memory, time, and technology

“Cole has been thrust from another world into ours and he’s confronted by the confusion we live in, which most people somehow accept as normal. So he appears abnormal, and what’s happening around him seems random and weird. Is he mad or are we?”

— Director Terry Gilliam

12 Monkeys studies the subjective nature of memories and their effect upon perceptions of reality. Examples of false memories include:

* Cole’s recollection of the airport shooting which is altered each time he has a dream.
* A “mentally divergent” man at the asylum who has false memories.
* Railly telling Cole “I remember you like this” when a barely recognizable Cole and Railly are seen in disguise for the first time.

References to time, time travel, and monkeys are scattered throughout the film, including the Woody Woodpecker “Time Tunnel” cartoon playing on the TV in a hotel room, The Marx Brothers movie Monkey Business (1931) on TV in the asylum and the subplots of monkeys (drug testing, news stories and animal rights). The film is also a study of modern civilization’s declining efforts to communicate with each other due to the interference of technology.

虛工作經驗

Posted on October 17, 2011 by rpflee

Curiosity 2.2 | 原地踏步

（安：我十分欣賞 Paul Graham 的文章。他的其中一個講法是，工作經驗的所謂「多少」，其實並不重要。真正重要的是，那些工作經驗，為你的想法帶來多少改變、為你的思考帶來多大提昇。在看 Paul 的文章之前，我從未聽過，有人對「工作經驗」，有這類的見解。）

Stephen Covey 和 Paul Graham 對「工作經驗」這個詞語的用法不同。Paul Graham 的「工作經驗」，是指工作年資，亦即是時間的長短。而 Stephen Covey 的「工作經驗」，是指對工作經驗的個人體會，亦即是 Paul Graham 所講，想法的改變和思考的提昇。雖然他們用字有別，但這一點上，有相同的見解。

Stephen Covey 都講過，你工作了 29 年，並不代表你真的有 29 年的「工作經驗」。如果你在那 29 年裡，都以同一個心態，用同一個處事方式，在同一個崗位，做同一類工作的話，你實際上只有一年的工作經驗。你有的，就只是第一年的工作經驗。其餘 28 年的所謂「經驗」，只不過是將第一年的經驗不斷重複。

— Me@2011.10.17

Another popular explanation is that wisdom comes from experience while intelligence is innate. But people are not simply wise in proportion to how much experience they have. Other things must contribute to wisdom besides experience, and some may be innate: a reflective disposition, for example.

One of the most powerful illusions of the human experience is the illusion that we’re seeing objective reality through our own perceptions. We can only see what we see.

We simply assume that the way we see things is the way they really are or the way they should be. And our attitudes and behaviors grow out of these assumptions.

Intellect 3

Intellect is invisible to the man who has none.

— Our Relation to Others, § 23

– Arthur Schopenhauer

Intellect is invisible to those have none.

（安：那是什麼意思？）

不聰明的人是不會感受到，聰明的東西究竟聰明在什麼地方。

假設有一個平庸的人，他的智力只有 100 個單位。假設有一篇上佳的文章，它的內容「智力」有 150 個單位。如果你把那篇上佳文章給那個平庸的人的話，他會覺得，那篇文章只值 100 個單位。他不會感受到那額外的 50 分在哪裡，因為以他自己的智力，不足以領會那高於他智力的 50 分。他會覺得，那篇上佳文章是沒有價值的。

而最麻煩的地方是，他因為沒有能力領會那高於他智力的額外 50 分，他根本不會覺得，自己的智力低於那篇文章。結果，他不單不會質疑自己的智力，反而只會責怪那篇文章的作者，浪費他的時間。
