(Continuation from yesterday)

Researchers and engineers have to model behaviors of element particle, human, nation and space, in their brain or computer, in order to continue their works.

There are some ways to make the model using from physical laws whose accuracy has been confirmed from both physics and logic to proper approximations. and I can say certainly the following.

"We, engineers, are expected to use mathematics like Miso or soy sauce."

In addition, when a new flavoring is released, our footwork to try the flavoring also expected as soon as possible.

For us, numeral or mathematics are important tool, as Kanji and English word.

In order to understand the above thought, it is enough for you to make am image of the world that we are prohibited to use about two thousand Chinese characters for daily use in Japan, and only are allowed to use less than five hundred Kanji only.

If the author couple could keep a level their work's quality, I can respect them profoundly .

But,

I have already released a same kind of message about English.

In this column, I argued that "let's change English in compulsory or high school education to a useful tool" with deleting the concept of CORRECT grammar, pronunciation, and so on.

So if this author couple's intention is positively

"let's change mathematics in compulsory or high school education to a useful tool"

and proposed the delete of quadratic equation, our trial seems to be almost same.

However, they are not so.
