Another pass way to mathematics

To especially the younger readers yeaning for mathematics

In some 40 years I had concerned with mathematics to which I only had read several books as if it is the books of arts, for example, the verses of Chinese classics that are always obscure to understand by my Chinese ability.

On the Tang Dynasty’s famous poet, DU fu’s work I had not clearly understood, probably till now. But the works are all pleasant in its own way.

As like them mathematics I had read some books and papers. Definitely I could not make DU Fu-like work. But I liked DU Fu so much. And I also cannot understand mathematics anymore, but also like it. If there be not valuation that is usual done at school, more people maybe like it as same as they read poems putted before them.

Mathematicians are put to study stern logics for its long history while the poets make poems that need severe rules of rhythm and meaning. That is all, for my standpoint on mathematics or Chinese classics or my life.

LETTER TO SEBASTIAN 7 JUNE 2021. PPS ADDED ON EDWARD SAPIR 15 JUNE 2021

Letter to Sebastian

Dear Sebastian,

Thanks a lot for your likes to my blogging.

I think that my papers and essays are of very narrow fields and themes, so I feel pleasant for your likes many times.

From last year Autumn to April this year, I kept on writing Essay on a researcher of French literature who died at 37 in 1976. I learnt French from him at university.

The days are 1970s and we were all young and eager to study towards future.

But everybody was in the confusion at those days after disturbance at universities.

I am also in the same situation.

I hoped to study linguistics but never found its way adequate to me . I only learnt several languages, Chinese, Korean, Russian, French and so forth.

At last my object and its way to learn were found in the end of the 20th century.

It was really a long and winding road as the Beatles sang at those days.

All were dear for me, all were thankful to the pioneers of language and mathematics.

Yours sincerely,

T.A.

One of pioneers of language is CHINO Eiichi 1932-2002, who studied Czech language at Czech and became authority on Old Slavic language. I learnt Russian language and the Linguistic Circle of Prague from him.

I ever wrote several essays on his memory.

Dedicated to CHINO Eiichi

Dear Sebastian,

The relation between language and time is at first given to me from Edward Sapir’s Language 1921.

Sapir’s concept drift is still very important for me.

For more details, refer to the following paper.

Edward Sapir, Language, 1921 Revised

Edward Sapir’s Language, 1921 showed me the dynamism of language proposing the concept, drift.

Drift shows us the macro phase of natural language and I was hinted by Sapir’s this concept and proposed the micro phase of natural language. The paper ”Quantum Theory for Language” 2003 is my first total proposal paper describing the natural language’s model.

SRFL Paper

Edward Sapir’s LANGUAGE AN INTRODUCTION TO THE STUDY OF SPEECH 1921 gave me a moment for study in 1980s while I was roaming about the darkness of not- getting any aim to study on language. I ever wrote a short paper being influenced in 2005 and after also wrote a memo on his book in 2014.Substantiality / 2005

Edward Sapir, Language, 1921 / 2014A moment came from his famous concept drift. At the near-end Chapter 7 Sapir wrote “the three major drifts“, that were the next .“The drift toward the abolition of most case distinctions“
“the correlative drift toward position as an accompanied“
“the drift toward the invariable word“
This “the three major drifts” are all apparently seen in Chinese, especially in the classical written language. At my age 20s and 30s I continuously had read Qing dynasty’s classical linguistic books and papers. WANG Guowei, ZHANG Binglin, DUAN Yucai, WANG Yinzhi were the most reliable works for me.

Letter to O. again.
When I could not find any object at the campus while I ruminated KIYOOKA's stanza at the before graduation, spring 1971

Letter to O. again

Dear O.

From TANAKA, again send a letter.
Thanks a lot for your kind letter although you are in every day busy work.
I had thought again sending a letter to you but I could not, for year-end thorough cleaning of my little house.

The fact is I uploaded the letter to you on my Blogger SRFL News, removing your private part.
This blog is still now ranked in the third position.

My blog is written by English so the readers are almost foreigners. But this blog is written in Japanese as same as the real letter to you. Your sincere thinking of old books may give the readers with agreement, who love the old books like you.

Blog's URL is the next.
https://srflnews.blogspot.jp/2017/12/letter-to-o.html

In your letter, you wrote that you would read the books comfortably not selling the old books of your work. I have also felt the same feeling so I bought Development of the modern poems written by ANDO Tsuguo who was the fine teacher of literature at the university and I once went to his home thinking to hear his intimate voice on poem and literature. He was one of the most typical poet and critic in the present age of Japan.

And now I would want to read KIYOOKA Takayuki's collected poems, that was ever read in my youth.

In autumn 1970 I was the senior of university, when the next spring I would graduate, I met with the thick French binding KIYOOKA's collected poems at the well drop-in bookshop of Hachioji, Tokyo. At that time I could not yet find my whole life object of learning.

In his book, I read a long poem titled "at the campus of university" in which he wrote that he meets with the whole life object of learning as he meets with his beloved person in his life.

The next spring 1971 I graduated the university, when I could not find any object at the campus while I ruminated KIYOOKA's stanza.

What I really met with my whole life object was already entered in the 21 century at my age 56 in 2003 after much trial and error. It was language universals that was ever taught from CHINO Eiichi who was the real life time teacher of mine and the successor of the Linguistic Circle of Prague, who spent 7 year study at Prague.

https://srfl-essay.webnode.com/news/from-distance-to-pseudo-kobayashi-distance/

Sergej Karcevskij gave me the great hint of approach to language universals through the famous paper titled "Du Dualisme asymétrique du signe linguistique" 1929.

In 2003 I wrote a paper titled " Quantum Theory for Language" after some trial papers, " On Time Property Inherent in Characters", " Manuscript of Quantum Theory for Language" .

In 2004 I wrote two attached papers, " Distance Theory" and "Reversion Theory".

Language and I 2017

Language and I

TANAKA Akio

Sekinan Library has researched on language from 1986 and successively at SRFL from 2003.
Papers and essays that have been written at Sekinan Library and SRFL Sekinan Research Field of Language
are shown and searched at SRFL Essay and SRFL Paper.
Sekinan Library's main theme is now at language universals that has been a hard target and researched since 1920s at Linguistic Circle of Prague, but the theme had been always put aside from the centre of the study.
In Japan. on Prague School CHINO Eiichi probably first introduced systematically through his direct study experience at Prague between 1958 and 1964.

I first met with him in 1969 at Tokyo, from whom received Russian language lesson at the beginner's small class.
And after some 10 years I again met him in 1979 at his lecture on structural linguistics, to which I listen till till March 1986 when I get apart from the university.

In 1986 I also started to study my own object on language, in which the main theme was language universals by mathematical description, surging from Nicolas Bourbaki, that were already applied to wide and deep approach even at human studies at that time.

For me algebraic geometry was the great aid to deepen the theme, to which from 1920s many researchers have recognised one of the most important but hard to operate with clear description at the field of philology.

In 2003 I narrowly wrote up the trial paper on language's characters, at that time not for total language, but I got the steady way to approach the hard target of language's basis mainly on meaning, through which I faintly could see the final target, language universals.
