Two dimensional time 5.2.3

Posted on by

The first time direction is uncontrollable; the second is controlled by making choices, traveling through different realities. Future is a set of parallel universes.

The first time direction, which is along the timeline, is uncontrollable, because one can only travel from the past to the future, not the opposite.

The second direction, which is across different timelines, is controlled by making choices, forming different realities.

Multiple dimensions of time

Posted on by

Two dimensional time 5.2 | 二次元時間 5.2

.

What would be the implications of multiple dimensions of time?

That means the (past) history itself can change, as commonly seen in time travel stories.

But wouldn’t that be the case with one dimension also?

In reality, there is only one dimension of time, meaning that the state of a system keeps changing, forming the timeline. But the timeline itself cannot be changed once formed. In other words, (past) history cannot be changed.

Life, 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

Posted on by

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.

The language of Change

Posted on by

Energy conservation, 6 | Energy 5

.

time ~ change

energy ~ the ability of causing change

Assuming

1. a system of one single particle

2. has only kinetic energy

3. and that kinetic energy is conserved.

conservation of energy ~ an object’s potential amount of 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}

— Me@2018-02-15 02:21:20 PM

Note:

The above argument has a bug:

If the mass m is constant, the kinetic energy E_K should be proportional to velocity squared v^2, instead of velocity v.

E_K = \frac{1}{2} m v^2

.

However, the above argument is still technically correct:

When E_K is constant, v^2 is constant. In turn, the magnitude of v also remains unchanged.

玄悟慧能 1.3

這段改編自 2010 年 4 月 18 日的對話。

第二，從「審美標準」問題中，你會發現，有時，不應把說話講得太盡。

無論你說「審美是主觀的」，還是「審美是客觀的」，都會有明顯的漏洞，因為有明顯的反例。所以，正確的答案，很明顯是「審美既不絕對客觀，亦不完全主觀」。換而言之，穏陣（萬無一失）的答案是，兩者之間。

但是，你又不要以為，有了這個「正確」答案，問題就解決了，沒有神秘感，因為，你仍然未知道，是「兩者之間」的哪一處。

同理，我覺得「人生注定」的答案是，「介乎『完全注定』和『完全不注定』之間」。換句話說，任何一件事情，以至整體的人生，都由很多「自主」和「外在」的因素所形成的。而「自主」和「外在」這兩大因素中，各自又由一些「必然」，和一些「偶然」的小因素組合而成。

「生命」這個詞語很有意思。

「生」，就是指一些可改變的東西，例如，「生活」、「生氣」和「生機」等。「命」，就是指一些不可改變的東西，例如，「命運」、「命定」和「命令」等。

人生，就是由「生」（可改變的東西）和「命」（不可改變的東西）所組成。

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.

Energy

Energy is the ability of causing change.

Change is related to time.

That’s why energy is related to time.

Application of Noether’s theorem allows physicists to gain powerful insights into any general theory in physics, by just analyzing the various transformations that would make the form of the laws involved invariant. For example:

  • the invariance of physical systems with respect to spatial translation (in other words, that the laws of physics do not vary with locations in space) gives the law of conservation of linear momentum;
  • invariance with respect to time translation gives the well-known law of conservation of energy

It is not the strongest of the species that survives, nor the most intelligent, but rather the one most adaptable to change.

— Charles Darwin misquotation

The definition of insanity is doing the same thing over and over and expecting different results.

If you are willing to change based on the feedback from the reality, many difficult things will become easy.
