Recently I have to read about AI technologies and economics, however in the book and Web site, I can find

"few table and figure".

This fact surprises me and annoy me.

Tables and figures are very convenience, because they can explain many things that are almost equal to 100 lines articles.

However, I feel ... how to say ... authors of the book and site, seems to stick not to use tables and figures.

I am not familiar with the pubbery, but I wonder if there is a custom or a culture of

"No life with tables or figures"

-----

I read the phrase "20% readers give up reading by reading each one formula"

This means, just five formulas in a book vanish all readers.. if you think "Ebata tells a lie", you are a person of "no problem about formulas".

"The numbers of reader who can think "initial readers x (0.8)^N (N=1,2,..N: numbers of formula)"

The person who can think the above at sight, can finish reading the book.

I am afraid that the readers are awful few.

At any rate, I think that the ratio of Japanese people in the science and engineering majors, is 35% (Ebata's estimation). In addition, the number who can use maths and statistics routinely is less than 10%.

Thinking of it, the thought of "no life with tables or figures" is a reasonable strategy in pubbery field,

However,

If the population of the people who can use maths and statistics comfortably increases, some interesting things may happen.

If most Japanese can do a trial calculation and check the accounts by spreadsheet, most politicians and half of bureaucracy should be retired.

Well, I know that it is just a dream.
