「附加數」比「基礎數」而言，艱深非常，大部分人也覺得，十分辛苦。但是，亦正正是因為「附加數艱深非常」，你才會覺得「核心數容易萬分」。

（問：程度高了？）

（問：無論是直升機，或者是鳥瞰圖，好像都是犯規？）

.

.

（問：似乎沒有。但是，那又好像十分辛苦。）

（問：我又不敢說，我一定會滿分。）

（問：不太敢，因為，那幾乎沒有可能。但是，我明白你的意思。現在要我做回中一的測驗卷，又真的會覺得，一定會高分，可能會滿分。）

Ken Chan 說：「你們現在會盤算，在會考中，各科太概會有什麼目標，奪取什麼等級的成績。但是，我當年全部科目，只有一個目標，就是要『攞 full』」。

# Ken Chan 去咗邊呢？

（邪惡地笑）

（但是，如果需要聯絡本人，可用右邊的電郵地址。）

~~~

「補習」一詞，給人「多餘」、「依賴」和「騙錢」的感覺。

「老師」一詞，給人「年老」、「沉悶」和「沒有發展」的感覺。

（至於他的在哪間大學任教和研究，我則不知道，因為，他沒有公開。）

# On Lisp

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.

# 避免犯錯 2

2015.06.23 Tuesday ACHK

6.54

My propositions serve as elucidations in the following way: anyone who understands me eventually recognizes them as nonsensical, when he has used them — as steps — to climb beyond them. (He must, so to speak, throw away the ladder after he has climbed up it.)

He must transcend these propositions, and then he will see the world aright.

— Tractatus Logico-Philosophicus

— Ludwig Wittgenstein

Before climbing a ladder, it is higher than you; after, you are higher than it.

# Cartesian Dualism 2

Transcend duality and non-duality

Duality is correct, in the sense that mind (software) and matter (hardware) are independent.

They are independent in the sense that a piece of software inside a computer (hardware) can be transferred or copied onto another computer. It can continue to exist even after that particular computer ceases to.

Non-duality is correct, in the sense that mind (software) is pattern of matter (hardware).

They are not two “things”. They are two aspects of the same “thing”.

# Autobiography in Five Short Chapters

I

I walk down the street.

There is a deep hole in the sidewalk.

I fall in.

I am lost … I am helpless.

It isn’t my fault.

It takes me forever to find a way out.

II

I walk down the same street.

There is a deep hole in the sidewalk.

I pretend I don’t see it.

I fall in again.

I can’t believe I am in the same place.

But it isn’t my fault.

It still takes a long time to get out.

III

I walk down the same street.

There is a deep hole in the sidewalk.

I see it is there.

I still fall in … it’s a habit.

My eyes are open.

I know where I am.

It is my fault.

I get out immediately.

IV

I walk down the same street.

There is a deep hole in the sidewalk.

I walk around it.

V

I walk down another street.

# Transcender love 2

Indifference 3

.

The opposite of love is not hate, but indifference.

— John T. Reed

.

I love you = I am you

I hate you = I am you but I don’t want to be

.

That is why love is a necessary condition of hate.

The best way to delete hate is to delete love.

No love, no hate.
