Genius 4

High school teachers are by nature non-intellectuals; students are by nature intellectuals.

As a mathematician there is a story I hear a lot. It tends to come up whenever I tell someone what I do for the first time, and they admit that they don’t really like, or aren’t very good at, mathematics. In almost every case, if I bother to ask (and these days I usually do), I find that the person, once upon a time, was good at and liked mathematics, but somewhere along the way they had a bad teacher, or struck a subject they couldn’t grasp at first, and fell a bit behind. From that point on their experiences of mathematics is a tale of woe: because mathematics piles layer upon layer, if you fall behind then you find yourself in a never ending game of catch-up, chasing a horizon that you never seem to reach; that can be very dispiriting and depressing.

To realize is to realize, 1.2.2

So in theory, there is no free will, because the future is already fixed, by the physical laws.

.

However, even if we knew the exact physical laws, it would be still logically impossible to get all the data of the present state of the whole universe, because it is logically impossible for any observer to observe itself, with 100% details, directly. For example, no camera can take a picture of itself directly.

So “in practice”, which is actually also “in principle”, there is free will, because logically, no one can predict, with 100% accuracy, your future actions.

.

In one logical sense, the future is already fixed, so there is no free will. In another logical sense, the future is fixed, but no observer can know that “fixed future” with 100% accuracy, so there is free will.

As a result, whether you label your actions are due to “free-will” or “not-free-will” has no real consequence. In other words, whether there is free will or not has no meaningful difference.

The difference that makes no difference makes no difference.

So you can actually transcend the free will problem altogether. You can just ignore it and live your life.

Or, you can somehow capitalize on this freedom of labelling your (future) life as either fixed or free, depending which label is more beneficial for you in a particular situation.

For example, when you are highly under pressure, you know that everything is fixed by the physical laws, from god’s point of view. When you are highly above pressure, you know that you are partially responsible for creating your own reality, because the future is not fixed for any one observer, for there is no “god’s point of view”.

You have the flexibility to label it in one way or another.

To realize is to realize, 1.2

For example, when you ask “how to be a polite person”, you become a polite person.

In other words, when you realize that you should be a polite person, that polite person is realized at that moment.

.

The ultimate self-fulfilling prophecies:

1. free will or not

2. god or no god

3. afterlife or not

4. future spouse exists or not

.

Why self-fulfilling?

1. free will or not

If we knew the exact physical laws and all the data of the present state of the universe, we would be able to predict, with 100% accuracy, the state of the universe at any future moment.

.

In theory, the exact physical laws exist, whether we know them or not. Also, in theory, all the details of the present state of the universe exist, whether we know them or not.

So in theory, there is no free will, because the future is already fixed, by the physical laws.

.

However, even if we knew the exact physical laws, it would be still logically impossible to get all the data of the present state of the whole universe, because it is logically impossible for any observer to observe itself directly. For example, no camera can take a picture of itself directly.

So “in practice”, which is actually “in theory”, there is free will, because logically, no one can predict, with 100% accuracy, your future actions.

魔法學堂

你不懂的「科學」,就為之「魔法」。你知原理和步驟的「魔法」,就為之「科學」。

讀書學習,就是化「魔法」成「科學」的過程。

在小說《哈利波特》中,魔法的原理和步驟,其實可以在魔法學校,學得到的。所以,那些所謂的「魔法」,其實是「科學」。

.

(問:但其中的「魔法」,十分奇幻。那真的可以稱為「科學」嗎?)

那只是因為,《哈利波特》小說宇宙中的物理定律,和我們宇宙的,不同罷了。

realize

1. (transitive) To become aware of

2. (formal, transitive) To make real

Sometimes, just realization itself is already a realization.

Realization has two meanings.

Sometimes, when you realize something, you realize that something at that very moment.

氣功

氣功有真有假。

健康的氣功,應不含宗教成份,應符合科學。

「真氣功」中的「氣」,是指「呼吸」。

健康的氣功,是透過呼吸的訓練,去促進血液循環。

量子力學 1.13.2 (外傳)

這段改編自 2010 年 4 月 3 日的對話。

這個問題,可以用剛才討論的那個例子來理解:

那彷彿就好像,你中了彩票,獲得了一千億元的獎金,存入了你的銀行戶口。但是,銀行的職員跟你說,你每日最多只能從那個戶口中,提款一百元。你就立刻發覺,窮你一生,甚至是十世的時間,都不能用盡那一千億元。如果你的朋友問你:「你是否擁有一千億元?」

你就唯有無奈地答:「那要視乎你『擁有』的定義。擁有而不能用,還算不算是『擁有』呢?」

(安:但是,你又真的可以,從那一千億元的戶口之中,每天提取一百元去用。因為那些一百元,始終是來自那一千億元的,你不能說,那一千億元完全沒有用,完全不屬於你。)

無錯。

可信而不可用,還有資格叫做「可信」嗎?

那要視乎你「可信」的定義。

(安:等一等。其實這個例子很有趣,彷彿正在講述「個人潛能」似的。

每人出世時也有無限的希望,帶著價值一千億元的潛能。但是,每天可以提取的潛能不多,而一生人的生命卻又十分短促。平均而言,一生人大概只有,三萬至四萬日的時間。那樣,一生人就只能把自己,約略萬分之一的潛能,化成現實。)

無錯,那實在十分可惜。

不過,人類發展各門知識和發明各種科技,本身既是「化潛能為實在」的過程,同時又是逐步解決「人生苦短」這問題的手段。知識為人,節省很多無謂時間。機器為人,承受很多沉悶工序。

另外,釋放潛能,雖則極為重要,但也只是人生的其中一個意義,並非全部。
