Sometimes there are some unfamiliar words in the book, or there are special explanations in need of special explanations, etc., which are hereby annotated.

For the sake of "ease of understanding", the explanation may not be "correct and scientific". Many nouns that are available on the Internet will not be specifically mentioned.

1. Mecha:

The definition of this book is a mechanical shell, a technological shell; Its significance lies in "putting the power of science and technology on the body", and controlling powerful technology with the powerful wisdom of people. In fact, today's technology is already beginning to take shape. There's a special name: wearable technology.

2. Photography and Control:

It can be thought of as a human feeling machine - controlling the whole set of actions and processes of the machine - paying attention to the 'process'.

For example: want to turn on the light (purpose) - find the switch (observe/take information) - press the switch (control the action) - turn on the light (result); This process can be seen as a kind of "camera control". At present, it is mainly used in intelligent control, robotics and other industries, and is a term used to describe machine actions.

(The name of Regency and Control Science was seen in some scientific materials, and Du Niang searched and did not find it for the time being.) What I found was about videography. ）

The definition of spiritual power in this book is the embodiment of wisdom and will, the immaterial extension of life. Take a separate chapter to explain. See above (Special Note: Mental Power).

4. Radar/Telescope:

In fact, the so-called radio telescope is radar. Many people think that telescopes and radar are two different things, but in fact, in the high-tech field, many times telescopes are radar; It may be easier to understand that radar can be thought of as a telescope of invisible light.
