機遇創生論 1.6.3

一萬個小時 2 | 十年 3

.

任何一門通用知識,起點都是「學海無涯,唯勤是岸」,終點都是「學海無涯,回頭是岸」。

「通用知識」的意思是,每人日常也需要知道的東西,例如,健康、財政、人際、時間管理等。

As we get older, generic reading becomes less and less useful. We then gain new knowledge mostly by personal life experience and directed reading.

— paraphrasing John T. Reed

那是指一般「通用知識」。

directed reading ~ research

至於「專業知識」,即是「技術細節」,結構和「通用知識」雖有相似之處,但不大一樣。

任何一門專業知識,由初學至成熟,則要大概十年的刻意用功。

這裡「成熟」的意思是「可用」;而「可用」的意思是「可以用來維生」。亦即是話,任何一門專業知識,由初學至可以用來作,長久穩定的賺錢工具,需要大概一萬個小時的有意識磨煉。

這裡的「十年」或「一萬個小時」,並不是精細的估計,而是數量級估計。換句話說,可以是七年、十二年,但絕不會是一年。

.

這就是「專業知識」和「通用知識」結構相似的地方——都是由最初的「學海無涯,唯勤是岸」,發展到「學海無涯,回頭是岸」。

而結構不相似的地方就是,對於「專業知識」而言,由「唯勤是岸」到「回頭是岸」的過程,需要長很多的時間(十年一萬小時)。二來,對於「專業知識」而言,「回頭是岸」(純熟到可以用來維生)只是里程碑而已,而不是終點。

Superpower

Impossible self, 2 | 電腦輪迴觀 4.2

.

ability 能力

~ you can access your own time to do things

.

power 權力

~ weighted ability

~ amplified ability

~ super ability

~ 超過一人之力

~ you can access also our people’s time to do things

— Me@2020-04-17 09:00:44 PM

.

Freedom is being able to make decisions that affect mainly you; power is being able to make decisions that affect others more than you. If we confuse power with freedom, we will fail to uphold real freedom.

— Freedom or Power?

— Bradley M. Kuhn and Richard M. Stallman

.

So the term “superpower” is actually redundant, because “power” already means “super-ability”, the ability to access more than one person’s time.

— Me@2020-04-18 07:41:36 PM

.

In daily life, “power” is often used as a synonym of “ability”. In this sense, “superpower” is the ability to access more than one person’s time.

In this context, with our people’s agreement, other people are your superpower. Also, you are our people’s superpower.

寧化飛灰,不作浮塵

And what of that truth which more than anything else gives me confidence in Hong Kong? The truth is this. The qualities, the beliefs, the ideals that have made Hong Kong’s present will still be here to shape Hong Kong’s future.

Hong Kong, it seems to me, has always lived by the author, Jack London’s credo:

“I would rather be ashes than dust,
I would rather my spark should burn out in a brilliant blaze,
Than it should be stifled in dry rot.
I would rather be a superb meteor,
With every atom of me in magnificent glow,
Than a sleepy and permanent planet.”

Whatever the challenges ahead, nothing should bring this meteor crashing to earth, nothing should snuff out its glow. I hope that Hong Kong will take tomorrow by storm. And when it does, History will stand and cheer.

最能使我對香港信心十足的事實又是甚麼呢?那便是港人的優良特質、信念和理想,不僅為-香港奠下了今天的基業,而且必會繼續為香港開創美好明天。

在我看來,香港一直在生活中實踐作家傑克˙倫敦的信條:

「寧化飛灰,不作浮塵。
寧投熊熊烈火,光盡而滅;
不伴寂寂朽木,默然同腐。
寧為耀目流星,迸發萬丈光芒;
不羨永恒星體,悠悠沉睡終古。」

前路不管有何挑戰,都不會,我重複,都不會使這顆流星飛墜,光華從此消逝。我深願香港-能奮然而起,征服未來,那時候,歷史也必為之動容,起立喝采。

事件實在論,更正

Event Realism | 事件實在論 6.1

.

exist = can be found

無後果,就不再存在。

— Me@2013.09.25

.

If the consequences of an event cannot be found anymore, that event no longer exists.

— Me@2019.09.05

.

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”.

— Wikipedia on Wheeler’s delayed choice experiment

.

「事件」並不完全「實在」。

實在 ~ 堅實地存在

仍然有後果的事件,才為之「仍然存在」。

永久地有後果的事件,才為之「實在」。

Visualizing higher dimensions

The trick of visualizing higher dimension is: not to visualize it.

— Wikipedia

— Me@2011.08.19

.

Besides trying to visualize, there are other methods to understand higher dimensions.

.

What is the meaning of visualization?

— Me@2018-09-02 4:35 pm

.

feel ~ receive all the data at once

(This definition is not totally correct, but is useful in the meantime.)

visual ~ feel at once through eyes

.

you can visualize a 3D object ~ you can see all of a 3D object at once

you cannot visualize a 4D object ~ you cannot see all of a 4D object at once

.

Actually, you can only visualize a 2D object, such as a square.

You cannot visualize a 3D object, such as a cube.

That’s why the screen of any computer monitor is 2 dimensional, not 3.

Life, 3

生命 3

.

We exist in time because time is change.

Growing is part of the definition of life. Growing is a kind of change.

.

Also, without time/change, there would be no thinking and no thoughts.

time ~ change

Time is logically necessary if change is necessary.

The language of Change 1.2

Energy conservation, 6.2 | Energy 5.2

.

time ~ change

energy ~ the ability of _keeping_ changing

.

constant velocity ~ the amount of an object’s change of position, measured with respect to its observer’s unit of change, is constant

s = \Delta x

v = \frac{s}{\Delta t} = \frac{\Delta x}{\Delta t}

.

kinetic energy ~ the amount of the ability of keeping changing an object’s position

\frac{1}{2} m v^2 ~ the square of (the amount of change of position, relative to the observer’s unit of change)

.

.

Energy difference is _not_ exactly a measurement of the amount of change, time interval is.
