Jeanne Grall



Jeanne Grall is a contemporary author of books on history.

She wrote in particular Girondins et Montagnard which deals with the French revolution. I read this book several years ago. Here is a translation of what I wrote about the book at that time:

This book gives some thickness to words that pupils find to the nausea in handbooks of history. Charlotte Corday leaves the famous painting and has parents, a childhood and a youth. One learns also that the hounded Girondins ran in the country as the resistant did one hundred fifty years later.

Bernare Gostiaux



Bernard Gostiaux, is a contemporary French mathematician.

B. Gostiaux is joint author of a book I have in my little mathematical library. This book, written in french and entitled Géométrie différentielle (differential geometry), was published in 1972. A search on the net shows that, since this date, Bernard Gostiaux published other books as single author and that the book I own was translated into english (with a 3rd author) under the title Differential Geometry: Manifolds, Curves, and Surfaces.

What is differential geometry ? Each time you use a map of a region of the world, you use differential geometry — a way to insert cartesian coordinates on something which is not ... cartesian, e. g. the surface of a sphere. But, "of course", this can be generalized to abstract numerical spaces, that is spaces whose elements are systems of numbers describing some reality. One can remark also that some vocabulary used by mathematicians in differential geometry is borrowed from geography : maps, atlasses, and used even in abstract case. According to my last infos, a student in mathematics, today, doesn't learn differential geometry before the 4th year in university.

Gauss



Johann Carl Friedrich Gauss, 1777 — 1855, was a mathematician of German culture.

Several important mathematical concepts are attached to his name, mainly the bell shaped  curve which is of central use in statistics and probabilities.

Less known are the Gauss integers  which are complex numbers of the form p + iq where p and q are rational integers. The set of Gauss integers has good properties and in particular the factoriality. Curiously, the number 2 which is prime in the set of rational integers is no longer so in the set of Gauss integers since one can write 2 = (1+i)(1-i) where the two factors are non-invertible in the set of Gauss integers.

Chain of events - 2/2



Back to the chains of events that led me to the project of entering dominican order in autumn 1960.

The second major event.

From the sink to my bed


It happened on an ordinary evening of one of my last school years in high school. I cannot say exactly which year. I was in "second" or in "first" but I was certainly not in "terminal".

This was the time when I secretly hoped that everybody had forgotten this etiquette of little-boy-who-will-enter-the-seminar; I avoided carefully to speak of it since I rather dreamed to do sciences, a matter where my results were good.

Just before going to bed, I am washing my hands in the sink of the kitchen (in the corner of the room, behind ++453++ on the photo below). My mother, in my back, says she did a visit to ++479++, the chaplain in high school. She says they talked about the future of her boys. When they spoke about me, she says that her words were exactly the following (I quote according to my memory) : "It would seem that his project is to enter the seminar" and she insists on "it would seem".

What my mother says has the effect on me of a very nasty shock.

Without saying any word, I finish washing my hands and go directly to my bed in the room where my two brothers and me sleep every night. While I am in the sheets, mother, certainly surprised by my silence, comes near my bed and asks, with some anxiety where one can guess dissatisfaction, whether I would have preferred that she did not speak of the seminar to the chaplain. I answer shortly "no" and, knocked, my mind does not find another thing to say.

During the days that follow, there is a course of religious instruction which takes place, I remember it well, in the room where we had our courses when I was in "third". I am intentionally late, willing to avoid a direct contact with the chaplain. The course is already running in front of a little group - we are never numerous if the subject is not catchy. I guess what is to happen and I have a stage fright. What I dreaded happens; the chaplain interrupts his speech and says to me that he wants to talk to me after the course.

So, after the course we talk, walking under the long glass roof which runs all around the immense and desert playground. "I was happy to learn that ..." I think he did not finished his sentence.

This first talk contained generalities. The chaplain says that becoming a priest brings great joys but also great sufferings. He asks me what kind of job I foresee. I'm completely taken by surprise. I answer the first thing passing through my head : "Like you, chaplain in a high school." But he replies quickly that his case is particular. In fact, I regretted immediately having said that. This is not at all my wish.

This is certainly on this evening that it was decided not to change anything in my situation before the second A-level.

And at no moment did come to my mind the idea to decide something else than to leave running this kind of machine which was triggered without my opinion. Because in fact, it is a matter of vocation, not of my opinion. "Vocation" that is to say "call by a high spiritual authority".

This is the answer to the question "Why didn't I strongly reacted explaining all around that this is an error, that I changed my mind, that I want to become an engineer and marry a girl ???"

A 500 pages book would probably be needed describing carefully the part of the society which was strongly impregnated by catholicism at that epoch. It would be necessary to describe the spirit - mystic and sentimental at the same time - which surrounded the word "vocation" and which was manifested by the seriousness and even fear that people had when they speak of a boy who will "become priest" or "enter the seminar".

And it would be necessary to speak about me, in the end of adolescence, enough informed of vilenesses of earth. The official teaching in high school did not have any word about the why of world and life. History courses are only description of events without ideological content. Literature shows many authors through their works but never presents them as masters of thoughts.

And for me, Catholicism always obviously remained the only society that reasonably works for the salvation - the difficult salvation - of mankind. Other religions ? I don't see the seriousness of christanism in notchristian religions. And protestantism is certainly the result of a misunderstanding which a bit of good will would certainly dissipate.

And what I hear, through the words of my mother on this evening, is : "Earth is full of miseries, sufferings and contemptible behaviours; your duty is to go and participate, in the structures of Catholicism, to its action of spiritual elevation, even if you would prefer to do something else." One probably would vainly look for a word or a gesture which explicitely made me understand this; however this is what I understood on that evening, in a fraction of a second.

A remark must however be added. The lines which precede are the echo of the rational plan and one can think from them that I see myself like a person who has a thing to do; however, the 500 pages book should certainly highlight it, I am rather inhabited by feeling that I must be, that I must become a character; this is my mission. And this explains my passivity. I "will let them equip myself".

Other essential notice, my religion is not at all nourished by images which Catholicism uses; I do not have the least phantasm on Jesus, the Virgin or the saints. My prayers are addressed to a remote God whom I think to honour the best by concentrating me on the meaning of each word that I pronounce. The idea that, for me, the project to enter the orders would have nevertheless the attraction to experiment some intimacy with an interior image is completely false.

P. M.



Chain of events - 1/2



Back to the chains of events that led me to the project of entering dominican order in autumn 1960.

It begins in the kindergarten.

1 Sisters of Wisdom

The Sisters of Wisdom were, I think, less than ten in the convent located on the parish. Each sister, normally, went after a few years and was replaced by another one.

The Sisters I have seen had, all day long, clothes and head-dresses exactly like in the photograph below. Their body dresses were of a light enough gray and were sufficiently long to leave only appear their ankles. The width of their sleeves were very large on all the length of the sleeves, down to the wrist. They had a huge rosary hanged to their belts; the grains were black, polished, and bigger than beans. They had all, also, permanently, a crucifix on the breast, exactly like on the photograph.


People could often see one or several of them walking without slowness in the streets of the neighborhood. In winter, they had a black pleated cape with a large pleated hood which covered them completely.

In the middle of their convent, they had their own chapel but a few of them were always present in the church of the parish at sunday mass and all other ceremonies. I can say it since, my family was assiduous too to all what happened in parish church.

The Sisters of Wisdom had the responsibility of the parish kindergarten and girls primary school. I spent the major part of my time at kindergarten in ++436++'s classroom. In fact, this sister was the only one with whom I had relations. At last, she showed special affection to me. The playlet where I said "On the contrary, it is very fine !" (see below) was organized by her. I continued to see her at catechism lessons after I leaved the kindergarten. She had the responsibility of first year catechism for boys in the parish. Lessons took place in one of the parish rooms. After that, ++436++ went elsewhere.

2 Kindergarten

I cannot say exactly howmany years I spent in the kindegarten before 1947 summer. The kindergarten is animated by two sister of wisdom nuns : ++435++ who has the age of a grand-mother and ++436++ who has the age of a mother. Despite its name, the kindergarten is a true first level primary school.

Religion is always present, centered on Gospel but not only. I remember that ++436++ explained that in the old days there was, in God's world, an important angel whose job was to carry the light. And I imagine that this world, with clouds and no earth below (certainly because of religious pictures) was dark because it needed some light. And ++436++ explains that the angel was too proud and became the first devil by cutting himself from God. In my mind of little boy, I don't doubt at all about the truth of this story.

I left the kindergarten to enter primary school in October 1948.

3 The playlet

This is the major event. It's a little fete which takes place in a classroom of the catholic primary school for girls of the parish. At (1) , ++437++ is in an arm chair. It is his birthday At (2) it's me and the crosses represent boys. I am not sure of it but I think that the palylet was played only by boys. The playlet consists in saying what jobs we will have in the future. Each boy expresses his project (not real, the dialogs are already learned) but I keep silent and don't want to express my future. A boy must say " It is so bad ? " (the tune is that of a question) and he says it. I must answer " On the contrary, it is very fine ! " and I say it. And finally I explain that I shall be priest.

The Portrait



A civil servant must not apply robotically the rules of law without knowing something about the society. The one who has income from taxes must know the events of the present and past times of people who pay these taxes. The civil servant must know something about the geographical and economical description of the space where live those who pay taxes.

The very minimum, when the tax receiver receives a banknote, is to have some knowledge about the person whose portrait is on the banknote.

Opininon



I was surprised by reading these lines in Studies in the Psychology of Sex by Havelock Ellis (downloaded from Project Gutenberg); underlined by me :

Traditional morality, religion, and established convention combine to promote not only the extreme of rigid abstinence but also that of reckless license. They preach and idealize the one extreme; they drive those who cannot accept it to adopt the opposite extreme. In the great ages of religion it even happens that the severity of the rule of abstinence is more or less deliberately tempered by the permission for occasional outbursts of license. We thus have the orgy, which flourished in medieval days and is, indeed, in its largest sense, a universal manifestation, having a function to fulfil in every orderly and laborious civilization, built up on natural energies that are bound by more or less inevitable restraints.

The consideration of the orgy, it may be said, lifts us beyond the merely sexual sphere, into a higher and wider region which belongs to religion. The Greek orgeia referred originally to ritual things done with a religious purpose, though later, when dances of Bacchanals and the like lost their sacred and inspiring character, the idea was fostered by Christianity that such things were immoral. Yet Christianity was itself in its origin an orgy of the higher spiritual activities released from the uncongenial servitude of classic civilization, a great festival of the poor and the humble, of the slave and the sinner. And when, with the necessity for orderly social organization, Christianity had ceased to be this it still recognized, as Paganism had done, the need for an occasional orgy.

An opinion that must certainly be known—without omitting any part of the statement.

Rabbits explanation

On the first photo below, one can see a global view of my youth home. The blue X indicates the place where there were rabbits. These rabbits were bred by mother's mother who lived in the house. When a rabbit was killed and eaten, the fur was kept, dried and sold to a man passing in the street. Just after World War II, a time when goods were missing in all domains, these furs returned in our home after preparation for clothes usage. And mother, who had good skill in sewing, made winter coats with them.

The three other photos were taken during the usual Sunday afternoon walk. I am with sister and brother J.

Note that the additional chimney through the window indicates that the first photo was taken some years after the three other ones, more precisely after the middle of years fifty when an oil-stove was installed in the corridor.

Much much more

2010 wed jul 28 - 8:45 pm, time of Paris.

French TV. About an important french politician: Michel Debré.

They speak of Debré's religion. They don't see the problem of words. One could call that the philosophical general relativity. How to qualify the faith of somebody using the words of dictionary? As if ideas were perfectly translated by a preexisting perfect language. The poorest thing is in the thinking that TV comments could, in a few words, describe correctly Debré's religion. The result is a few standardized sentences: "he was this, his father was that...". Poll sentences in front of an unfathomable reality of existence.

Philosophy is much much more difficult than anything else.

Symphony

A thing that becomes possible when one is retired: conduct moments of days like a maestro conducting a symphony.

In activity life, there are continuously moments when one cannot stop what one does; one cannot wait to take a breath, to think about what will be the most convenient thing to do next.

When retired, it's possible. Like a maestro slowing the orchestra in a meditative movement.

This note is far reaching. Human life is imagination about using time harmoniously.

Though the publisher is french - a venerable institution located at Grenoble - the text is in english. But this english is easy and mixed with technical words that are not in the usual dictionary (paracompact, holomorphic ...)

This is pure mathematics; this means that the questions that are developed in the article will not be directly used for practical purpose, e. g. to solve one of the great problems of mankind (cancer ...). However, history of sciences shows that applied mathematics (the "useful" mathematics) depend strongly on pure mathematics, need strongly their coherence and the strength of their logic.

Leonardo Fibonacci



Leonardo Fibonacci, circa 1170 — circa 1250, was an
Italian man.

L. Fibonacci is known by basic mathematicians as the person whose name was given to a famous sequence of numbers.

The years of his birth and death are not exactly known. He was an italian man of a time when european learned people paid more attention to Holy Books than to mathematics. But Fibonacci had his education in north Africa where he was in contact with the arabic mathematics world.

I show below how the sequence of Fibonacci numbers is generated. I start with 0 and 1 (leftmost column) which are the two first numbers. I add these numbers : 0 + 1 = 1 ; the result 1 will be the third number (second column). So the sequence has now three numbers 0,1,1 . I add now the two last numbers of the sequence : 1 + 1 = 2 ; the result 2 will be the fourth number (third column). And so on. The sequence is infinite.

Christmas 194?


In the large kitchen of home. In front of the door-window since father's camera was a black parallelipipedic box of the simplest kind without flash.

(post scriptum for the one who has already very detailed informations. Indeed, there was another camera at home; a much smarter one with an opening door and a deploying accordion. But this camera never worked.)

Michael B. Feldman



Michael B. Feldman, born in 1944, is a retired US professor of computer science.

M. B. Felman's name is associated to Ada, a programming language which has its origin in the US army. No matter the opinion one has on the action of US army, Ada is now a good worldwide used language with a lot of available free documentation and even a handbook which gives all good reasons to adopt Ada. This language is mainly targeted to enterprises but an individual can have a free ada compiler on a PC and experiment in Ada programmation. I did it using in particular M. B. Feldman manuals.

June 29, 1960



In great catholic seminaries, school year ends on June 29, Saints Peter and Paul day which is the day chosen for ceremonies of ordination. It is the strongest moment in year, stronger than Christmas and Easter. It is the day when those who have thought and studied for long years are going to receive the mission to celebrate the mass and quit the seminary for function in a parish. At Poitiers in 1960, they are about a half dozen.

During the long ceremony of ordination which takes place in the cathedral, the rites surrounding the ordination of new priests are in the center. But previously there are also minor orders and the important step of sub-diaconate where the seminarist takes the vow of chastity.

For me, the intention did not change. After the summer holidays, I will go in to Angers 's dominican noviciate. I have at first a meeting with the superior of the seminary who was planning to make me do the military service by going before the call. I announce him thus my decision.

I had also to visit the bishop of Poitiers. He receives me without sitting in a large richly old-furnished hall. He has some words dubitationing on my religious vocation, adds that he regrets almost to not have sent me in Paris and finishes laughingly a bit: "I didn't say it to you." (exactly « Je ne vous ai rien dit. ») The interview ends by his benediction which I receive, according to the custom, a knee earthen and kissing his episcopal ring.

I reported the conversation to my director of conscience who dispelled my fears: It is the normal obstruction of hierarchy.

My plan is now known of everybody. I spent a day in the convent of Angers during the vacation of Easter. I see for the first time the novices' master and talk with him in his room. I certainly also had a first visit of the building but, except the long two travels in bus, my other memories on that day stay a bit blurred.

The mine of gold



Maybe Universe is the result of chance, or maybe its state is the result of a will. According to what I think of that there are two ways for conducting my existence.

If Universe is the result of chance, nobody knows whether the phenomenon "Universe" will be repeated after the foreseen end of this one. We are in a kind of mine of gold and everybody struggles to get a big part of this gold. Everybody is my enemy.

Otherwise, the question is, of course, "Who ?". And whatever the answer may be, my attitude is different from the case of a mine of gold. I shall naturally try to participate to construction and by the way own fairly a part of the result.

Reflection about, "the person", about "my person", about how I am leads to the conclusion that my existence is itself a relation: being is "being with". This, in my mind, is the university-level reformulation of what is taught to children "God is Love".

We are not in a mine of gold.
