The year 2024 is getting stronger and stronger one day.
Learning questions millions. To be a dime a dozen.
Make a list, it might be as long as a street.
There are many disciplines in one discipline, and each subject has its own boundaries between knowledge.
There is a clear distinction between them, and the barriers are towering into the sky.
For example, there is no communication between disciplines, and secondly, learners cannot remember and understand a lot of knowledge in their own disciplines.
For example, writing an 800-word essay is higher than climbing to the sky, and it is more difficult than Shu Dao.
Abstract concepts are like one stone after another. Carry it up the hill and roll it down naturally.
Three loose structures. There is no such thing as a systematic cognition.
Knowledge is one, like an elephant, while absorption is fragmented. You can only enter little by little, slowly.
What you see may only be a part.
This time it's the elephant's left front leg, next time it's the elephant's trunk, and again the elephant's ears.
Once inside, it may take a long time to splice together to form a complete elephant.
Fourth, learners find some tools, such as mind maps, to form a set of knowledge systems.
This is a method and strategy.
And there are many problems, no matter how beautiful your mind map is, it may be just a vase, just a good look.
There are many branches, which exceed the constraints of the seventh magic of the laws of psychology.
Because there are some core things that are not resolved.
That is, your cognition is at the same level as the problem, and there are so many problems that you can never solve them.
Therefore, I am born with an end, but knowledge has no end.
The problem of learning in the discipline is nothing more than how to digest and absorb knowledge, use knowledge, regenerate knowledge, and so on.
Many learning questions arise around this knowledge.
Knowledge is based on words and symbols, and when we see words, can we use the laws of mathematics to solve the problems of knowledge?
This knowledge can be divided into three categories, one is stable and known;
One is changing, so it is unknown, and the knowledge of change is always changing;
The knowledge in the middle bridges the two, and the knowledge that exists at the same time as stability and change is the third type of knowledge.
With such knowledge, after learning, the boundaries between knowledge are not so obvious.
So we focus on the third type of knowledge.
Knowledge that is stable and can be changed, that is, knowledge that can draw inferences.
It is possible to solve the problem of learning.
Changing knowledge derives from unchanging knowledge.
Knowledge metabolism.
The knowledge of change is like a mathematical function.
Assign a number and get a result.
In the definition field of the function, the corresponding value range is obtained.
And the function of knowledge words, assigning a specific text, to get a new knowledge.
It is a "function" of the same structure.
What is stable and constant is the "function" of this text.
This function comes from the basic immutable knowledge, first introduce this learning tool, the context map.
What is a contextual map?
A context map is a network of keywords.
The key word is a PLMAT-n type word.
It comes from asking questions with 5w1h.
That is, the element of one thing, PLMAT-N is the form of statement from 5w1h.
The simplest one is the P character A action M object, the subject-verb-object. The backbone component of a sentence.
Write a paragraph in the form of a collection.
Exercise: Wang Zengchu's prose.
Filter for keywords.
The form of the collection is as follows: ship = perimeter =
Surface = Shore =
Temple = Below this collection is turned into the form of a contextual map. The context diagram is below.
It is a traveling space, a scene to observe.
When you draw a contextual diagram, you use the structure of the contextual diagram.
Extract the letters of its class. It becomes a contextual diagram with PLMAT-N, called the general term formula.
Turn it into a general formula.
Find a set and constrain these variables to a certain range.
You change a carrier, walking on the mountainside bus, train, plane, sedan chair and so on.
Train=Peripheral=
Site = re-assign the text to this general formula.
Got a new piece of content.
Assignment. 
This is a function of words.
Migrate elsewhere with mathematical analogies.
The problem of learning becomes a mathematical problem, which is universal.
When learning, find the function of the word, which is the general formula.
Exhaust the structure and context diagram of the same type.
x=plmat-n
Once upon a time there was a mountain, and there was a temple on the mountain, and the temple had three little monks...
For example, the type of three little monks, that is, the branching story. Such a structure can be used.
Change again. 
Then upgrade x=plmat-n
up to the structural formula.
Branched. 
It's a lot of variations.
Such a structure is stable. And the content is changing.
Rise to the level of theory and law.
Learn this knowledge that can be reproduced repeatedly.
Let's address the knowledge of those changes.
Knowledge about classes is relatively stable.
Upgrade your cognition and move up to the next level.
I have read so many books and so many articles, do they have anything in common?
Knowledge in books is made up of sentences, and there must be multiple key words in a sentence.
Keywords If you use the form of a mind map, it is a structure.
Is there any other structure?
Is there a common structure behind the words you see?
No matter what the discipline is, their common element is keywords, keywords involve keywords connected to it, through a keyword, can more keywords be stretched?
Just looking at the text, it's linear lines.
Look at the paragraphs again to form some of the merged blocks.
And the author's line of thought may be a huge network.
Stephen Pinker said: The difficulty of writing lies in the use of a tree-like structure to reflect the unfolding of the first sexuality.
That's the law behind the problem of learning, just find this network.
First, the keyword is transformed into the form of a mathematical set, which is a function, and the structure is a form that can be written as a set.
All learning questions will be integrated into the network.
Because it's interconnected.
And this network is a system at a higher level of problem.
That contextual map is just such a tool. It can reproduce the author's thoughts.
Learning problems, transforming them into math problems, into networks of contextual diagrams.
Take memorizing words, for example
Use contextual maps to memorize words.
After sorting. 
After becoming a context map.

Write with a contextual map.
Here are some of the stories in Journey to the West.
Contextual maps run through a part of the learning process.
Unifies a part of the areas of learning.
There's a piece of material here, and you can use this tool.
Try to make a contextual map.
Next time, I will provide you with a reference context map.
