How to improve the world indefinitely?

There is law of conservation of energy.
There is law of conservation of mass.
But, there is no law of conservation of ideas.

If you have an apple and I have an apple, and we exchange apples, we both still only have one apple. But if you have an idea and I have an idea, and we exchange ideas, we each now have two ideas.

— George Bernard Shaw

. . . 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, …

You are an A person. You befriend with an F person. The result is that your friend becomes a better person, you become a worse person. In theory, you become a C person. Your friend becomes a C person. In practice, since being a bad person is much easier than being a good person, you two will become both F people. — Me

回到過去 3

Cumulative concept of time 20

你想回到過去,重新經歷年青時的生活。但是,你有沒有想過,「經歷」即是「走過」,又名「離開」。「經歷過去」,其實就即是「到達現在」。

(Me:那樣,如果我只是「回到過去」,但不「經歷過去」,我豈不是不會「失去青春」?)

無錯。但是,回到過去,但不經歷過去,即是停止時間。這個現象,學名叫做「英年早逝」。那不是好事。

但是,你亦不用灰心,因為,「經歷過去」或者「到達現在」,並不代表你「失去過去」。「現在」,就是「經歷了的過去」。「過去」,是「現在」的一部分。「過去的你」,是「現在的你」的一部分。你從來也沒有失去過,年青時候的自己。

正如,「使用金錢」的意思是,令它消失,從而換取其他,更有價值的東西。「使用金錢」而不開心,是因為你花太多的金錢,去買了一些,用處不大的東西。

同理,你覺得「失去」青春,是因為你沒有百分百地利用,當時的時光,去賺取最多的經驗,累積最多的財富,創造最多的作品。

2.3.1 What is statistics

Data Statistics Information Studying Knowledge Aging Wisdom Dying Next What is Next?

Data and Information

First, differentiate data and information: Data is raw. Data have no meaning. Information is processed data. Information has meaning. The process to transform data to information is statistics.

Information and Knowledge

Information is higher-level than data. What is higher than information?

Knowledge.

What is the process of transforming information to knowledge?

Studying. (or AI for computers)

If you want a lot of mathematics information, just buy 50 maths books, then you get a lot of information. But if you want a lot of mathematics knowledge, you have a lot of hard work to do.

Knowledge and Wisdom

After knowledge, what is next? Wisdom.

What is the process of transforming knowledge to wisdom?

Aging.

If you want to have a lot of knowledge, buy a lots of books, read them and read them well. But if you want to have a lot of wisdom, you need to live your life for a long time or a long long time.

Wisdom and Next

Is there anything higher than wisdom? If yes, what is the process to go from wisdom to there?

Dying. (This can be trivial. When you age to certain extent, you die.)

Now, the common paradigm is that the teacher-student ratio is critical — fewer students means higher-quality teaching. But if you turn your students into teachers, you gain leverage. You move the fulcrum over.

Time Mind I

我最核心的興趣是:

1. 什麼是時間? What is Time? –> So I study Physics.

2. 什麼是心靈? What is Mind? –> So I study Psychology.

3. 什麼是自我? Who am I? –> So I study Philosophy.

以上是我十八歲時所想的。

Categorifying Fundamental Physics

A fundamental fact about quantum theory is that these operators fail to commute: aa* – a*a = 1 in units where Planck’s constant is 1. Remarkably, this fact has a simple combinatorial interpretation: there is one more way to add an element to a finite set and then remove one, than to remove one and then add one.

You cannot teach a man anything, you can only help him to find it for himself.

To be catalyst is the ambition most appropriate for those who see the world as being in constant change, and who, without thinking that they can control it, wish to influence its direction.

The best doctors found a middle position where the were neither over-whelmed by their feelings nor estranged from them. That was the most difficult position of all, and the precise balanceneither too detached nor too caring – was something few learned.

6.4.0 Create = teach or write or both

6.4.1 Create: Teach

6.4.2 Create: Write

.

The basic theme is that whenever you cannot understand something, you should try to create that thing.

How to create?

Write. Write as if you are explaining the materials to someone else.

As physicist Gerar’td Hooft advised, when reading a physics textbook “… imagine how you would write those texts in a smarter way.”

Why is that you can understand a thing when you re-write your textbook?

It is because whenever you write, you have to translate the materials into your own language.

You are CREATING your OWN knowledge.

6.3.2 Quantum Mechanics | 量子力學

.

When physicist Feynman was a student,
there were two versions of Quantum Mechanics.
They described the same thing
but in different mathematical languages.

One version was Heisenberg’s Matrix Mechanics (矩陣力學) , using matrices. Another was Schrodinger’s Wave Mechanics (波動力學), using differential equations.

Feynman could understand neither of them.
So he spent 8 years to create
his own version of quantum mechancis
in order to understand quantum mechanics [1].

Feynman’s version of quantum mechanics is now called
Feynman path-intergral. (路徑積分)

After Feynman’s death, [2] people found that Feynman had written some words on the left-hand top corner of his blackboard:

.

“What I cannot create, I do not understand.”

不是由我自己想出來的東西, 我都不能理解.
