Job: Marketing

Ever wonder what the difference is between sales and marketing?

The official definition is that marketing creates demand, while sales fulfils demand.

Self Reliance 6

Everybody searching for a hero
People need someone to look up to
I never found anyone to fulfill my needs
A lonely place to be
So I learned to depend on me

– Greatest Love Of All

– by Michael Masser & Linda Creed

喜歡的影子總找不到
舊日賢人舉世亦無
總找不到心中想景仰的
想景仰的英雄 我只好改變我
令我自豪

– 至愛

倘有飛天術 都要力氣飛高
但朝和暮 人多聲聲怨道
天氣沒有估計那麼好

倘有隱身力 都要唸咒確保
日星移換 神仙都需要做
可笑是世間卻羨慕

Translation 2

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.

Blackboard 2

6.3.1 Feynman’s Blackboard

.

Physics
= Relativity + Quantum Mechanics
= 相對論加量子力學
= 深深深

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.

.

真誠朋友

A:
人與人的關係,可能悲慘到什麼地步?

B:
你能想像得到的悲慘關係,世間都有;
你無法想像得到的悲慘關係,世間亦有。
沒有悲慘至極這回事。悲慘無極。

— Mr. Lee

.

被朋友出賣, 屬正常.
被朋友遺棄, 屬自然定律.
可以難過, 但毋須傷心.

有朋友無條件地對你好, 是奇遇.
有朋友在你有難時為你出頭, 是奇蹟.
要更加好好珍惜.

你, 可以做到別人的真誠朋友嗎?

“Why not?”

4.15 Shaw

1. You see things as they are and ask, “Why?” I dream things as they never were and ask, “Why not?” — George Bernard Shaw, Back to Methuselah (1921)

2. Reasonable people adapt themselves to the envirnoment; unreasonable adapt envirnoment to themseleves. Therefore, all human progress are made by unreasonable people. — George Bernard Shaw, Maxims for Revolutionists (1903)

3. Do not follow where the path may lead. Go instead where there is no path and leave a trail. — Muriel Strode ( ? )

Feynman

4.11 A physics career

A young man wrote physicist Feynman a letter, asking how to know whether he was suitable for a physics career. Feynman gave the following reply:

“I say this. Try to find some friends who are somewhat interested in physics and try to discuss physics things with them. If you find yourself able to explain things in your own words, so that they are led to understand things from what you say, you are OK. Soon you will find yourself able to explain things to yourself. Otherwise, give up and plan for a different career. If you can’t find such friends, try to tutor elementary physics, and see how it goes.” [12]
