多重小宇宙 1.2 | 二次元時間 2.6 | Dimension 1.3.6 | Two dimensional time 2.6 |  A little bit of yourself, 2 | 心靈互聯網 2 | Mind Internet 2

這段改編自 2010 年 4 月 3 日的對話。

但是，記住，那只能作比喻，而並不是實情，因為所有的「主觀時間線」，都會同時影響和受制於同一條「客觀時間線」。任何兩個人，即使從不相遇，兩條「主觀時間線」永不相交，他們的人生歷程，也不可能百分百互不相干。任何一條「主觀時間線」，都不如我所講的「平行宇宙」一般，有機會獨立存在。

不過，你這個講法雖然不是鉅細無遺，但是極度有用，因為它帶出了一個超級重點。現實世界的時間，雖然只有一個次元，但那一個次元，就已經足夠難明了。

剛才我把「一次元時間」講成一條「時間線」或者「因果鏈」，只是為了方便簡化。實情是，「時間」是一個「因果網絡」。意思是，「因」和「果」並不是一一對應。一個「因」，可以引發多個「果」；而一個「果」，又可以來自多個「因」。比喻說，一個學生，會有很多老師；而一個老師，又會有很多學生。「一因多果」和「一果多因」，可以統稱為「多重對應」。

你「現實版二次元主觀時間」的講法，雖然不是分毫不差，但是可信可用，因為，現實世界的「因」和「果」，是「多重對應」的。

Science

Posted on by

In both social and natural sciences, the body of positive knowledge grows by the failure of a tentative hypothesis to predict phenomena the hypothesis professes to explain; by the patching up of that hypothesis until someone suggests a new hypothesis that more elegantly or simply embodies the troublesome phenomena, and so on ad infinitum.

生疏荒廢

石頭永固 2 || use it or lose it || 不進則退 不用即棄

.

人的腦海之中，有一個「機會成本評價系統」，會自動刪除「沒有用」的才能，以節省記憶和時間資源。

「沒有用」既可以指「本身沒有用」，又可以指「本身有用 但不拿出來用」。對於「機會成本評價系統」而言，兩者沒有分別。

才幹以外，感情亦然。

無限循環

Posted on by

A time to fear, 4 | Recursion 8

人害怕「不確定性」，簡稱「未知」、「未定」、或者「不安」。「未知」是知識狀態；「不安」則是情緒起伏。「未知」導致「不安」。

人腦的特定是，時刻都想確定，下一步應該怎樣做。「不確定性」導致人腦，不能立刻決定，下一步的行動是什麼。那樣，人腦就會處於，一個「不斷企圖做決定，但又做不到決定」的無限循環（infinite loop）、跳上跳落的躍動狀態：

要做決定 –> 資料未夠–> 再試 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> 要做決定 –> 不行 –> …

所以，「未知」導致「不安」。

對電腦程式來說，要打破一個「無限循環」，要麼到達「終止條件」（terminating condition / boundary case）；要麼乾脆把它，從程式碼中刪除。

對人腦心靈而言，要結束一個「煩惱不安」，要麼有新的資料，導致做到決定；要麼索性把它，從思考中忘記。

簡而言之，要麼「解結」，要麼「斬結」。

Dear Esther

Posted on by

To get a feeling of dying, play the video game Dear Esther till the end.

— Me@2012.12.16

When you finish a video game, you go back to the real world;

when your real world is over, you go back to your realer world.

— Me@2012.12.21

There is another theory, that in a car crash, Esther was put in a coma, and the voice is her husband talking to her, in hopes that she can hear him. She wanders along beaches and through caves that are filled with sometimes strange things, things that are bits and fragments of what she is hearing and what her mind is putting together. At the end when Esther jumps, it is possible her heart rate increased, showing up on the hospital monitor, which would explain the voice at the end saying “Come back,” and the darkness at the end would probably be her dying in the coma.

變通

Easy 3

“Easy” in Chinese is “容易”, literally meaning “able to change“.

It is not the strongest of the species that survives, nor the most intelligent, but rather the one most adaptable to change.

— Charles Darwin misquotation

The definition of insanity is doing the same thing over and over and expecting different results.

— Albert Einstein misquotation

If you are willing to change based on the feedback from the reality, many difficult things will become easy.

Move on

Posted on by

Yes, this city needs Bruce Wayne. Your resources, your knowledge… not your body. Not your life. That time has passed.

Remember when you left Gotham? Before all this, before Batman? You were gone seven years. Seven years I waited, hoping that you wouldn’t come back. Every year, I took a holiday. I went to Florence, there’s this cafe, on the banks of the Arno. Every fine evening, I’d sit there and order a Fernet Branca. I had this fantasy, that I would look across the tables and I’d see you there, with a wife and maybe a couple of kids. You wouldn’t say anything to me, nor me to you. But we’d both know that you’d made it, that you were happy. I never wanted you to come back to Gotham. I always knew there was nothing here for you, except pain and tragedy. And I wanted something more for you than that. I still do.

Alfred Pennyworth: I’ll get this to Mr. Fox, but no more. I’ve sewn you up, I’ve set your bones, but I won’t bury you. I’ve buried enough members of the Wayne family.

Bruce Wayne: You’ll leave me?

Alfred Pennyworth: You see only one end to your journey. Leaving is all I have to make you understand, you’re not Batman anymore. You have to find another way. You used to talk about finishing a life beyond that awful cape.

進步成本估算

Posted on by

這段改編自 2012 年 12 月 6 日的對話。

如果你想數學成績，有明顯的進步，你就要有基本的盤算。你要知道，大概每做多少道練習題目，你才會在考試中進步一分。然後，再問自己，你想進步多少分。　

如果你平均每做二十道題目，就會進步一分，而你想進步的分數是，至少十分的話，你就要在試前，試做和改正，起碼二百道題目。

Mathematicians won the war.

Mathematicians broke the Japanese codes and built the A-bomb.

Mathematicians… like you.

In medicine or economics,

in technology or in space,

battle lines are being drawn.

To triumph we need results — publishable, applicable results.

Now, who among you will be the next Morse,

the next Einstein?

Who among you will be the vanguard of democracy, freedom and discovery?

Today we bequeath America’s future into your able hands.

Welcome to Princeton, gentlemen.
