I believe that we all read books , When reading blog , But a lot of the time , We read one blog after another , Book after book , When I see the same content in a few days , I still feel strange .

So I want to share it with you today , How to better compress , Memorizing knowledge .

Let's start with an example , There are 7 Idioms :

* make threatening gestures
* have a definite object in view
* lofty ambition
* Handsome
* hundred-percent
* behaviour
* immensely proud
Suppose you want to remember this 7 Idioms , The way I used to go to school , Read it several times , Force yourself to remember , It can be remembered in a short time , But an hour later , Two hours , one day , Two days later , Forget it .

Students said , I have another trick , You can turn short-term memory into long-term memory , It's simple , every other 1 I'll remember , Think about it for a long time , I remember it slowly , Repeat the memory according to the increasing time cycle .

But it's a waste of time , Let's look at a more interesting way to remember , Or the words just now , Let's rearrange the order :

* make threatening gestures
* lofty ambition
* immensely proud
* Handsome
* have a definite object in view
* hundred-percent
* behaviour
Did you find anything ?

No, …

If I extract one word from each word :

Zhang Hongyang is not handsome

Remember that , I don't think you'll forget that in a short time , According to this sentence, push it there 7 Idioms , It's also a very relaxing thing .

In fact, this is what we said , Don't learn by rote , We have to memorize it by deduction .


Yes, of course , You might say , You are all prepared words , How can there be such a coincidence in real life , That's right , It's hard to find such a perfect example of compressed knowledge in real life . So I'm going to share my experience with a real case .

<> case

Last week I read an article by Mr. Zhu on the subway , speak A/B Tested , I didn't pay much attention to that before , But after the headlines , find A/B
The test was very good , So I'm very interested in this article , Also want to learn , about A/B The focus of testing , It can be used to measure the actual situation at work .

In this paper, the A/B The test mentioned 10 Points :

* Never trust your intuition too much ;
* The number and distribution of experimental samples are important ;
* The dimensions of analysis should be as comprehensive as possible ;
* Other group changes A/B Impact of testing ;
* The trend of comparison values must be convergent , Not divergent ;
* Data embedding point , The buried point and collection of data are A/B Key to successful testing ;
* Form a process , Or design a tool ;
* Try to give each result a reasonable explanation ;
* Redesign the experiment when necessary ;
* Different clients were tested separately ;
My first thought was to remember that 10 Points , It's easy to do in the future and products A/B Let's blow it .

I read it in my mind several times , however 10 There are too many , Turn off the phone and forget .

therefore , I open the note , The above contents have been readjusted :
Don't trust your intuition Sample size allocation Prevent other experimental influences Re experiment if necessary Consider different dimensions The result should converge Separate analysis of different platforms Give each structure a reasonable explanation Burying point Formation process
Don't you think it's changed , In fact, there are two changes :

* There is less writing ;
* Classified ;
You can see that I fall into four categories , What are the four categories ?
Do it AB test -> How to do it AB test -> How to analyze AB test result -> Summarize the whole process .
These four categories are progressive , It's very easy to remember .

So it's now :
Do it AB test ; Don't trust your intuition How to do it AB test ; Sample size allocation Prevent other experimental influences Re experiment if necessary How to analyze AB test result ; Consider different dimensions
The result should converge Separate analysis of different platforms Give each structure a reasonable explanation Summarize the whole process Burying point Formation process
Is it easy to remember a lot , There are classifications in ,10 The knowledge is much clearer .

Of course, it's not over .

Then I did another thing , Because second , The third category , There are still too many :
2. How to do it AB test ; - Sample size allocation - Prevent other experimental influences - Re experiment if necessary
Extracting keywords , become :

sample , independent , repeat -> Independent repeat sample

We also extract keywords for the third category :
3. How to analyze AB test result ; - Consider different dimensions - The result should converge - Separate analysis of different platforms - Give each structure a reasonable explanation
Extracting keywords :

Multi dimensional analysis of different platforms , The results of convergence are explained

ok, Now? 10 The bar becomes :
1. Do it AB test ; - Don't trust your intuition 2. How to do it AB test ; - Independent repeat sample 3. How to analyze AB test result ; -
Multi dimensional analysis of the platform , The results of convergence are explained 4. Summarize the whole process - Burying point , Formation process
If you did this in paper notes , You can do it :

Give you a condensed word or sentence , Mark out the core words , Remind yourself that the annotation needs to be expanded .

okay , The above process is what I remember AB Test the flow of this article , I can remember whenever I want to . If I remember it the way before , I guess 10 Minutes later , I can only remember two .

<> summary

Today I passed a practical example to share with you how I usually remember these trivial knowledge , We can see that today's article is relatively close to reality .

Last but not least :

Compressed sentences or words do not necessarily need to have practical meaning

Just like the beginning of the article, you try to remember by Zhang Hongyang 7 Idioms , In fact, Zhang Hongyang is not handsome , But this sentence still helps you complete the memory .

Remember when you were in high school 9 It is an essential amino acid for human body , Teachers also use similar methods to help us remember , When you were in high school 9 Is kind of amino acid hard back still have what skill , Welcome to share .

Finally, this article describes the above behavior , It's all done on the subway ,mark A picture as a souvenir .

That's what I want to share with you , But not necessarily for everyone , Please try with a questioning attitude , If it works for you , Feel honored .
