Academics From France

"The man who no longer expects miraculous changes either from a revolution or from an economic plan is not obliged to resign himself to the unjustifiable. It is because he likes individual human beings, participates in communities, and respects the truth, that he refuses to surrender his soul to an abstract ideal of humanity, a tyrannical party, and an absurd scholasticism. . . . If tolerance is born of doubt, let us teach everyone to doubt all the models and utopias, to challenge all the prophets of redemption and the heralds of catastrophe. If they can abolish fanaticism, let us pray for the advent of the sceptics."

"Buffon, the director of the Jardin du Roi... watched... the sun... Besides him.. stood... his latest experiment: four large wooden frames holding between them an array of over 150 mirrors. Screw threads ensured that each mirror was precisely aligned... Buffon had been inspired to conduct the experiment by the famous story of how... Archimedes defended his hometown from an attack by the Roman fleet... [by] [[w:Archimedes#Heat ray|focus[ing] the sun's rays onto the ships' wooden hulls]]. ...In 1747, at the age of thirty-nine, [Buffon] felt it was time to make his mark... Within two minutes the deal plank began to char, then to smoke. Just as it looked as if it would burst into flames, however, the sun disappeared behind a cloud. ...That summer, crowds flocked... to see the now celebrated scientist set fire to buildings over two hundred feet away."

"What better way to establish his name than to tackle the most fundamental philosophical question man could ask: When was the world created? And how? ...Unlike all previous theorists, Buffon chose to ignore the Bible. ...Instead, his inspiration came from Newton. ...he believed that Newton's mechanics would enable man to unravel the mysteries of the universe. If Newton's laws could explain the motion of the moon and planets... why shouldn't they also reveal our history?"

"Buffon produced in the fifty years from 1749 an Histoire Naturelle... one of the signal products of eighteenth-century science. ...He attempted to see nature as a whole, produced a vast synthesis and sought to give a picture of the history of the earth... [If] Newton had appeared to reduce the inanimate world to a system of law, Buffon... set his mind on a similar achievement, and even a wider one—comprising... biological phenomana and expanding into the realm of history. ...Along with Leibnitz he believed that the earth had once been in an incandescent state... part of the sun, but had broken away after a collision with a comet. He rejected the tradition that this globe was only six thousand years old and made an attempt to set out the periods or stages of its history; a time when mountain ranges were formed...a time when waters entirely covered... the globe... and a time when the continents came to be separated from one another. ...He held something like Leibnitz's idea that every plant and animal was composed of a mass of minute particles, each of which was a pattern of the whole individual; and this enabled him to explain the origin of living creatures without reference to an act of creation. He tried to show that no absolutely definite boundary existed between the animal and vegetable kingdoms. Nature always proceeds by nuances, he said."

"Never think that God's delays are God's denials. Hold on; hold fast; hold out. Patience is genius."

"Le style c'est l'homme."

"La génie n'est utre chose qu'une grande aptitude à la patience."

"[F]rom the earliest periods of time [man] alone has divided the empire of the world between him and Nature. ...[H]e rather enjoys than possesses, and it is by constant and perpetual activity and vigilance that he preserves his advantage, for if those are neglected every thing languishes, changes, and returns to the absolute dominion of Nature. She resumes her power, destroys the operations of man; envelopes with moss and dust his most pompous monuments, and in the progress of time entirely effaces them, leaving man to regret having lost by his negligence what his ancestors had acquired by their industry. Those periods in which man loses his empire, those ages in which every thing valuable perishes, commence with war and are completed by famine and depopulation. Although the strength of man depends solely upon the union of numbers, and his happiness is derived from peace, he is, nevertheless, so regardless of his own comforts as to take up arms and to fight, which are never-failing sources of ruin and misery. Incited by insatiable avarice, or blind ambition, which is still more insatiable, he becomes callous to the feelings of humanity; regardless of his own welfare, his whole thoughts turn upon the destruction of his own species, which he soon accomplishes. The days of blood and carnage over, and the intoxicating fumes of glory dispelled, he beholds, with a melancholy eye, the earth desolated, the arts buried, nations dispersed, an enfeebled people, the ruins of his own happiness, and the loss of his real power."

"Man alone consumes more flesh than all the other animals together devour; he is, then, the greatest destroyer; and this more from custom than necessity. Instead of using with moderation the blessings which are offered him, instead of disposing of them with equity, instead of increasing them in proportion as he destroys, the rich man places all his glory in consuming, in one day, at his table, as much as would be necessary to support many families: he equally abuses both animals and his fellow-creatures, some of whom remain starving and languishing in misery, and labour only to satisfy his immoderate appetite, and more insatiable vanity, and who, by destroying others through wantonness, destroys himself by excess. Nevertheless, man, like some other animals, might live on vegetables."

"I was always deeply uncertain about my own intellectual capacity; I thought I was unintelligent. And it is true that I was, and still am, rather slow. I need time to seize things because I always need to understand them fully. Even when I was the first to answer the teacher's questions, I knew it was because they happened to be questions to which I already knew the answer. But if a new question arose,usually students who weren't as good as I was answered before me. Towards the end of the eleventh grade, I secretly thought of myself as stupid. I worried about this for a long time. Not only did I believe I was stupid, but I couldn't understand the contradiction between this stupidity and my good grades. I never talked about this to anyone, but I always felt convinced that my imposture would someday be revealed: the whole world and myself would finally see that what looked like intelligence was really just an illusion. If this ever happened, apparently no one noticed it, and I’m still just as slow. (...)At the end of the eleventh grade, I took the measure of the situation, and came to the conclusion that rapidity doesn't have a precise relation to intelligence. What is important is to deeply understand things and their relations to each other. This is where intelligence lies. The fact of being quick or slow isn't really relevant. Naturally, it's helpful to be quick, like it is to have a good memory. But it's neither necessary nor sufficient for intellectual success."

"Mathematics, politics and butterflies were the three great loves of Laurent Schwartz."

"Schwartz never offered blind allegiance to Left or Right. Above all he was, in his own words, a man who hated to see systems not working properly."

"I have always thought that morality in politics was something essential, just like feelings and affinities."

"Trotskyism gave me … a remarkable education, clearly more advanced and sophisticated than that of most youngsters of my age. But by the extremism and sectarianism of its ideas, and by its stereotyped language, it neutralised me during the occupation. My judgment remains extremely severe on my own actions as well as those of the majority of the Trotskyist party during that period."

"To discover something in mathematics is to overcome an inhibition and a tradition. You cannot move forward if you are not subversive."

"It strikes me that mathematical writing is similar to using a language. To be understood you have to follow some grammatical rules. However, in our case, nobody has taken the trouble of writing down the grammar; we get it as a baby does from parents, by imitation of others. Some mathematicians have a good ear; some not (and some prefer the slangy expressions such as 'iff'). That's life."

"You see, some mathematicians have clear and far-ranging. "programs". For instance, Grothendieck had such a program for algebraic geometry; now Langlands has one for representation theory, in relation to modular forms and arithmetic. I never had such a program, not even a small size one."

"If Serre was a Mozart, Grothendieck was a Wagner."

"Je pourrais dire, en exagérant à peine, qu’entre le début des années cinquante jusque vers l’année 1966, donc pendant une quinzaine d’année, tout ce que j’ai appris en "géométrie" (dans un sens très large, englobant la géométrie algébrique ou analytique, la topologie et l’arithmétique), je l’ai appris par Serre, quand je ne l’ai pas appris par moi-même dans mon travail mathématique. C’est en 1952 je crois, quand Serre est venu à Nancy (où je suis resté jusqu’en 1953), qu’il a commencé à devenir pour moi un interlocuteur privilégié - et pendant des années, il a été même mon seul interlocuteur pour les thèmes se plaçant en dehors de l’analyse fonctionnelle. - Grothendieck, Récoltes et Semailles."

"One day, I had to give a lecture at the Chevalley Seminar, a group theory seminar in Paris. [...] When I got to the room, fifteen or so researchers were there, along with a few students seated in the rear. A couple of minutes before the talk was to start, Serre came in and sat in the second row. I was honored to have him in the audience, but I let him know right off that the presentation might not be very interesting to him. It was intended for a general audience and I was going to be explaining very basic things. [...] At the end of the seminar, Serre came up to me and said—and here I quote verbatim: “You’ll have to explain that to me again, because I didn’t understand anything.” [...] the most troubling aspect was the abruptness, the frankness with which Serre had overplayed his own incomprehension. It takes a lot of nerve to listen closely to a presentation, then go up to the speaker, smile, and tell him that you “didn’t understand anything.” I never would have dared. Why did he do it? I first told myself it must be one of the things you have the right to do when you’re Jean-Pierre Serre. Then I realized that could also work the other way: what if this technique had actually helped him become Jean-Pierre Serre?"

"It not by reason of the egoistical satisfaction of our private vanity that the world-to-day pays homage to savants. No; it is because it knows that a savant really worthy of the name devotes a disinterested life to the great work of our epoch—I mean to say to the improvement, too slow, alas! for our taste, of the condition of every one, from the richest and happiest to the humble, the poor, and the suffering. That is what the public declared nine years ago in this same hall when honouring Pasteur. That is what my friend Chaplain has tried to express on the beautiful medal which the President of the Republic will presently offer me. I do not know if I have completely fulfilled noble ideal traced by the artist, but I have tried to make it object and end, the directing idea of my existence."

"Hence the rôle of savants, as individuals and as a social class, has unceasingly developed in modern states. But our duties towards other men increase in the same ratio, and let it never be forgotten; let it proclaimed in this hall, in this palace of French science."

"A new conception of human destiny results from a profound knowledge of the universe and the physical and moral constitution of man, directed by the fundamental notions of universal solidarity between all classes and all nations."

"[Berthelot] is not only a great chemist, but also a great philosopher. He possessed a universal spirit. His discovery of the synthesis of organic materials would be enough to immortalize his name. His work on explosive materials were also invaluable services..."

"According as the bonds uniting the peoples of the world together are multiplied and lightened by the progress of science and by unity of the doctrines and precepts that it deducts from facts, and imposes without violence and yet in a relentless manner to all convictions, these ideas have assumed a growing and more and more irresistible importance. They tend to become a purely human basis of nature, morality, and politics."

"Marcellin Berthelot... observed ants as a hobby. He published in 1886 under the title Science et philophie... several essays. One... "Les cités animales et leur évolution". ...He was convinced that the same instinct of sociability was active among human races and among animal ones. He considered the hypothesis of the social contract as a chimerical one. ...Ten years later, in another collection of essays... Science et morale... [h]e considered that it is more useful to compare human societies with ant colonies than with beehives, because while in the latter laws are uniform, in the former there is a place for individual intitiatives."

"The most interesting of the services rendered by science is perhaps shown by comparing the servile and miserable condition of the popular masses in the past with their present state, already so much raised in dignity and comfort, without prejudice to the hopes which they are gradually realising."

"Is there still a statesman who doubts the services greater still that may be expected from this incessant progress?"

"Science is the benefactor of humanity."

"Thus it is that the tangible utility of scientific results has made the public authorities understand that laboratory work should be encouraged and sustained, because it is economically a benefit to all and for the public health."

"Science carries its legitimate pretensions further. To-day it claims the material, intellectual, and moral direction of society. Under its impulse modern civilisation marches with an increasingly rapid stride."

"Gentlemen, since the first half of the century that has terminated, without going further back, the world has strangely altered. The men of my generation have seen come into play, beside and above the nature known since antiquity, if not an antithesis, a counter-nature... but a superior nature, and to some extent transcendent, where the power of indıvidual is centupled by the transformation of forces until then unknown or not understood, borrowed from light, magnetism, and electricity."

"Berthelot... says that alchemy rested partly on the industrial processes of the ancient Egyptians, partly on the speculative theories of the Greek philosophers, and partly on the mystical reveries of the Gnostics and the Alexandrians."

"In 1851, at the age of twenty-four, he entered the College de France, as préparateur of the lectures on chemistry (under Balard, the discoverer of bromine)."

"During the siege of Paris, Berthelot was President of the Scientific Committee of National Defence, and was occupied in the manufacture of explosives, and in 1883 he published, in two volumes, his work, Sur la Force des Matieres Explosives... a valuable contribution to the science..."

"His laws are... (1) The heat disengaged in any reaction is a measure of the chemical and physical work accomplished in the reaction. (2) The total thermal value of a reaction is dependent only on the initial and final states of the changing system. (3) "The Law of Maximum Work," or "the theorem of the necessity of reactions"... This law is the fundamental principle of Berthelot's thermo-chemistry: "The quantity of heat evolved in a reaction measures the sum of the physical and chemical changes which occur in that reaction"—"ce principe fournit la mesure des affinités chimiques.""

"In 1864 Berthelot began his great work on thermo-chemistry, and in 1879... published... Essai de Mécanique Chimique fondée sur la Thermo-chimie."

"Berthelot's agricultural station and laboratory were at , and here experiments on vegetable soils, the fixation of atmospheric nitrogen in soils by the agency of microbes, the action of electricity on the growth of plants, etc., were conducted. Berthelot states that twenty-five pounds of per annum per acre might be fixed by bacteria."

"He also formed by passing the vapour of and sulphuretted hydrogen over hot copper; and by the action of carbon monoxide on a hot solution of caustic potash, was produced, the formate yielding on distillation with ."

"His methods were simple and direct. By means of the electric spark, and united to form ; or [acetylene was also obtained] by... [sparking] a mixture of hydrogen and ...or by... spark[ing] a mixture of hydrogen with vapour, or ."

"He formed by the action of the electric spark on a mixture of and ."

"Although glycerine was discovered by Scheele in 1779, and its formula established by Pelouze in 1836, it was not until 1854 that its true composition was known... [when] Berthelot... proved that it is an alcoholic compound capable of interacting with... acids as acetic and palmitic."

"Berthelot was quite sure that physics and chemistry would soon solve the problem of aerial navigation, and he significantly remarked that when they do so " customhouses will fall of themselves.""

"In 1860 Berthelot's Chimie Organique fondée sur la Synthèse, was published. It was the first... based entirely on synthesis."

"[O]f the numerous syntheses of Berthelot, or the building up of chemical compounds, many... were [previously] only obtained [naturally] through... life, either animal or vegetable."

"His scientific labours were immense, and he completely revolutionized chemistry in more departments than one. He transformed agriculture; proved that inorganic and organic bodies obey the same laws; established "la théorie des affinités"; and invented thermo-chemistry."

"Probably the most important syntheses of his are the production of acetylene from carbon and hydrogen, and methane or marsh gas, by means of the well-known Berthelot's reaction; and of dynamical chemistry, his most important discovery is "the law of maximum work.""

"The first half of the nineteenth century was devoted to analytical chemistry—this being due to the great work of Berzelius. The second half, however, was the era of Berthelot or synthetical chemistry."

"Although Wohler, in 1828, produced artificially, and Kolbe synthetized in 1845, Berthelot was undoubtedly the creator or founder of organic synthesis."

"He produced over a thousand memoirs, embracing every department of chemistry."
