Zooming out

Posted on by

In this morning’s dream, I had seen an ultra zooming out of the universe, where in the end the universe became a particle of a super-universe.

Perhaps the afterlife (or near-death experience) is like this kind of bizarre feeling.

— Me@2011.08.17 

It is a fractal.

— Me@2011.08.22

Note: This kind of feeling is unhealthy, since it is induced by eating too little food.

— Me@2017.01.09

Several months ago, I had another this kind of super-feeling dream, in which I could get a time traveling feeling.

Euler Formula

Posted on by

Exponential, 2
 

a^x

general exponential increase ~ the effects are cumulative
 
e^x

natural exponential increase ~ every step has immediate and cumulative effects

— Me@2014-10-29 04:44:51 PM
 

exponent growth

e^x = \lim_{n \to \infty} \left(1 + \frac{x}{n}\right)^n

~ compound interest effects with infinitesimal time intervals
 

multiply -1

~ rotate to the opposite direction

(rotate the position vector of a number on the real number line to the opposite direction)

~ rotate 180 degrees
 

multiply i

~ rotate to the perpendicular direction

~ rotate 90 degrees
 

For example, the complex number (3, 0) times i equals (0, 3):

3 \times i = 3 i
(3, 0) (0, 1) = (0, 3)
 

multiplying i

~ change the direction to the one perpendicular to the current moving direction

(current moving direction ~ the direction of a number’s position vector)
 

exponential growth with an imaginary amount

e^{i \theta} = \lim_{n \to \infty} \left( 1 + \frac{i \theta}{n} \right)^n

~ change the direction to the one perpendicular to the current moving direction continuously

~ rotate \theta radians

To check whether a project is your true love, ask yourself:

Am I willing to spend INFINITE time on it?

Wittgenstein’s ladder

Posted on by

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.

End-of-history illusion

Posted on by

The end-of-history illusion is a psychological illusion in which individuals believe that they have experienced significant personal growth and changes in tastes up to the present moment, but will not substantially grow or mature in the future. Despite recognizing that their perceptions have evolved, individuals predict that their perceptions will remain roughly the same in the future.

The illusion is based in the fact that at any given developmental stage, an individual can observe a relatively low level of maturity in previous stages. The phenomenon affects teenagers, middle-aged individuals, and seniors. In general, people tend to see significant changes in hindsight, but fail to predict that these changes will continue.

Fasting creates new brain cells

Posted on by

So, what’s going on?

Well, when they examined the brains of the fasting mice.

They found something extraordinary. 

These green objects are newborn brain cells.   

These three here are brand new?

Sporadic bouts of hunger actually trigger new neurons to grow.

Why should a brain start to generate new nerve cells when you stop feeding it?

If you think about this in evolutionary terms, it makes sense.

If you’re hungry, you’d better increase your cognitive ability.   

That will give you a survival advantage, if you can remember where the location of the food is and so on.

It seems that fasting stresses your grey matter the way that exercise stresses your muscles.

So hunger really does make you sharper?

Yes. We think so.   

Mark’s research is starting to point towards a simple conclusion.

Alternate day fasting has better effects on the brain than does a lower-amount-of-daily-calorie restriction.

It’s true of mice, but he needs to do proper human trials to prove it’s true in us.   

I’ve come to the end of my search to find out how to eat, fast and live longer.

The official advice is, eat at least 2,000 calories a day, and if you really want to fast, even on an intermittent basis, see your doctor first, because there are people it could harm such as pregnant women or those who are already underweight.

二百萬 2

Posted on by

這段改編自 2010 年 4 月 10 日的對話。

.

我覺得，「談戀愛」主要是令到兩個人快樂。但是，「認真工作」卻可以令到無數人快樂。例如，我的工作是學術、教學、寫作等。任何一樣我只要認真經營，都可以大大改善，很多人的一生。

但是，那不代表「談戀愛」和「認真工作」不可共存，因為，還有一個可能性，就是我的戀愛對象，和我有共同的人生目標，都想改善這個世界。那樣，我和她就可以互為助手。

如果沒有共同或相近的人生目標，拍拖（談戀愛）的過程中，就很可能會充滿，很多無意義的活動和劇情。那就大大浪費了我，很多原本可以用來，轉捩其他人的時間。（「轉捩」在此作動詞用。）

相反，如果可以互為助手，那就相當於二人合力，去創造一個嶄新的世界。共同創作，可能是拍拖過程的，最美滿版本。

氣功

Posted on by

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。

Change

Posted on by

By the definition of “time”, anything in time must be changing. Anything not in time, such as the dead, cannot change.

If you do not keep changing for better (improve, grow), you are effectively dead.

Although this paragraph is not 100% accurate, its spirit is useful.

共同理想

除了建立家庭外，很少情侶有共同理想。

長久而言，那會導致「談戀愛」時，沒有什麼好談。

這段改編自 2010 年 4 月 10 日的對話。

.

拍拖（談戀愛），是一個「互相改變」的過程。

無傷大雅的缺點，你可以選擇不改，因為更改太快太多，會十分煩厭。但對於事關重大的缺點，你不敢不改。

要發現和改正自己的缺點，往往需要一個，十分瞭解你的人，加以提醒和指導。而拍拖，就正正是那個「互相修正」和「互相創造」的過程。

「不斷修正」和「不斷創造」的後果是，雙方各自也不斷重生成，新版本的自己。二人對於對方來說，也會不斷帶來新鮮感。那樣，愛情方能長久。
