‎Die Zeit Constantin's des Grossen. - [REINTERPRETING GIBBON]‎

‎Basel, 1853. 8vo. A little later green hcloth w. simple handwritten paper title label to spine. Some leaves brownspotted. VII, (1), 512 pp.‎

‎First edition of the first publication of any of Burckhardt's books, his fist major publication, the important and influential ""The Age of ConstantinE the Great"".Burckhardt's ""The Age of Constantine the Great"" was the first work to describe an ""Age of Constantine"". It was also the first work of a series of cultural histories that Burckhardt had planned. The series was supposed to begin with the age of Pericles and end with that of Raphael, and that of Constantine became the first to appear. The work founded the basic structure of his other later cultural histories, namely representing what he considered the three great powers: state, religion and culture. Burckhardt eminently describes transitional periods and periods of crises, and this work deals with the transition from late pagan Antiquity to early Christian Middle Ages.The age of Constantine is here considered as the necessary transition from Antiquity to the Christian era and as such it is also understood as the basis of the culture of the Middle Ages. In opposition to the historians of his time, Burckhardt portrayed the Emperor Constantine negatively, as a calculating politician only concerned with preserving his own power, whose turn toward Christianity was purely speculative and driven by politics. He is thus portrayed as wholly unreligious and as having the sole goal of dominion. The work and the portrayal of Constantine caused the greatest controversies within religious and historical circles. The work became hugely influential and many later historians were inspired by both the controversial portrayal of Constantine, which they applied to other historical figures as well, as well as of Burckhardt's theories of the transition between the two eras. The Swiss historian of art and culture, Jacob Chrisoph Burckhardt (1818-1897), contributed seminally to the historiography of these two fields. He is considered the discoverer of the Renaissance, and with his later main work, ""Die Cultur der Renaissance in Italien"", he founded the study of thirteenth- to fifteenth-century Italy and thereby the historical study of the Renaissance, the society of which he dealt with all aspects of. In general, Burckhardt's works all constitute an original historical approach to the study of art, culture, social institutions etc. As a highly respected scholar of Greek civilization, Burckhardt, with his original historiographical approach, was highly admired by Nietzsche, who also attended his lectures. The two kept in contact and corresponded frequently. Like Nietzsche, Burckhardt was a great admirer of Schopenhauer, and he greatly opposed the Hegelian interpretations of history.""Outstanding among his (Burckhardt's) writings are, besides the books on Italian art and civilization, ""The Age of Constantine the Great"", 1853, in which he reinterpreted Gibbon, and the two posthumously published books...""

‎All papers first apperance. All 5 of extreme importence in the development of the Calculus. Leibniz' 2 papers on the catenary curve (paper 1-2 offered here) was written at the instigation of Jacques Bernoulli. Following the example of Blaise Pascal, who had initiated, in 1658, a contest for the construction of the cycloid, Leibniz also provoked the geometers of his time, by challenging them to submit, at the fixed date of mid-1691, their geometric method for the construction of the catenary curve. Leibniz later provided the answer, followed by Johann Bernoulli and Huygens.'These two papers are a historical account of the origin of the study of this transcendental curve, and, at the same time, the first physical-geometric construction showing the species-relationship between the catenary and the logarithmic curves, as two companion curves" one arithmetic, the other geometric. All of the differentials of the catenary curve, are arithmetic means of corresponding differentials of the logarithmic curve" and, all of the differentials of the logarithmic curve, are geometric means of the catenary.'""The Catenary is the form of a hanging fully flexible rope or chain (the name comes from ""catena"", which means 'chain'), suspended on two points. The interest in this curve originated with Galileo, who thought that is was a parabola. Young Christiaan Huygens proved in 1646 that this cannot be the case. What the actual form was remained an open question till 1691, when Leibniz, Johann Bernoulli and the then much older Huygens sent solutions to the problem to the ""Acta"" (Jakob Bernoulli, 1690, Johann Bernoulli 1691, Huygens 1691 and Leibniz 1691), - these 4 1691-papers offered here - in which the previous year Jakob Bernoulli had challenged mathematicians to solve it. As published, the solutions did not reveal the methods, but through later publications of manuscripts these methods have been known. Huygens applied with great ( paper 4) virtuosity the by then classical methods of 17th century infinitesimal mathematics, and he needed all his ingenuity to reach a satisfactory solution. Leibniz ( the papers 1-2) and Bernoulli (paper 3), applying the new Calculus, found the solutions in a much direct way. In fact, the catenary was a test-case between the old and the new style in the study of curves, and only because the champion of the old style was a giant like Huygens, the test-case can formally be considered as ending in a draw."" (Grattan-Guiness in ""From the Calculus to Set Theory, 1630-1910."").The paper by JACOB BERNOULLI ( no. 5 offered here) is a milestone papers as it marks the invention of the ""SYSTEM OF POLAR COORDINATES"" with points located by reference to a fixed point and a line through that point. Although newton had earlier also devised such a coordinate system (in 1671), his work was not known, so that the credit for the discovery generally goes to Bernoulli.

In ""Notatiuncula Constructiones Lineae"" Bernoulli proposed a solution to non linear equations which today is one of the most common used solutions of the general fluid. Bernoulli equations are significant because they are nonlinear differential equations with known exact solutions. In the ""Specimen dynamicum"" Leibniz presents a conception of body and force which distinct between primitive and derivative forces and between active and passive forces. This article is regarded as being the clearest exposition of Leibniz' dynamics. (DSB VII, 151b).""The first attempt at a detailed account of the dynamics was a long dialogue, the ""Phoranomus seu de potentia et legibus naturae,"" written in July 1689 while Leibniz was in Rome. This was quickly followed be the composition of the massive Dynamica de potential et legibus naturae corporeae (1689-90) [...]. Though it was written with the intention of publication, and though Leibniz work at publishing it, he never considered it entirely finished and it remained unpublished during his lifetime.The later [...] he finally revealed some of the metaphysical foundations of the project in an essay [the present paper]."" (Garber, Daniel. Leibniz: body, substance, monad. 2009. 132 p.)""Its title suggests a summary of or a selection from the earlier work [...].

‎First appearance of the famous issue of Acta Eruditorum in which the 4 solutions by the 4 most eminent mathematicians at the time, were printed together. There were in all 5 solutions to the posed problem, and Newton's solution was first printed in the Philosophical Transactions (January 1697) and reprinted here. The solution proposed by L'Hopital, not printed here, was not published until 1988.The brachistochrone problem was posed by Johann Bernoulli in Acta Eruditorum in June 1696. He introduced the problem as follows: ""I, Johann Bernoulli, address the most brilliant mathematicians in the world. Nothing is more attractive to intelligent people than an honest, challenging problem, whose possible solution will bestow fame and remain as a lasting monument. Following the example set by Pascal, Fermat, etc., I hope to gain the gratitude of the whole scientific community by placing before the finest mathematicians of our time a problem which will test their methods and the strength of their intellect. If someone communicates to me the solution of the proposed problem, I shall publicly declare him worthy of praise."" Johann Bernoulli and Leibniz deliberately tempted Newton with this problem. It is not surprising, given the dispute over the calculus, that Johann Bernoulli had included these words in his challenge:- ....""there are fewer who are likely to solve our excellent problems, aye, fewer even among the very mathematicians who boast that [they]... have wonderfully extended its bounds by means of the golden theorems which (they thought) were known to no one, but which in fact had long previously been published by others.""According to Newton's biographer Conduitt, he solved the problem in an evening after returning home from the Royal Mint. Newton: ... ""in the midst of the hurry of the great recoinage, did not come home till four (in the afternoon) from the Tower very much tired, but did not sleep till he had solved it, which was by four in the morning.""Newton send his solution to his friend Charles Montague and Montague published anonymously in the Transactions. Newton's solution, presented here in the Acta, is also anonymous. The episode did not please Newton, as he later wrote: ""I do not love to be dunned [pestered] and teased by foreigners about mathematical things ..."" After the competition Johann Bernoulli said "".... my elder brother made up the fourth of these (after Leibniz, himself and Newton), that the three great nations, Germany, England and France, each one of their own to unite with myself in such a beautiful search, all finding the same truth.""Struik (Edt.)

‎The papers represents one of the first announcements of Berzelius' discovery of the fixed chemical proportions, determining the weights and valencies of the various constituent elements in inorganic compounds. The papers were published at the same time in Swedish, German (both here in Annalen and in Schweiger's Journal), and in French. By running many hundreds of analysis of chemical compounds he gave so many examples of the law of definite proportions that the world of chemistry could no longer doubt its validity, and in so doing he gave experimental evidence to the atomic theory. He hereby laid a solid fundation for the further development of chemistry. A reprint is found in Ostwald's Klassiker der exakten Wissenschaften, No. 35.According to Söderbaum (Jac. Berzelius, 2, p.12) ""It was a giant work, one of the most importent in the history of chemistry, which was here presented. One is even more impressed when one remembers that it was a pioneer undertaking in every sense of the term. Analytic and synthetic methods existed before Berzelius' time, to be sure, but there were no precise methods of the sort which he required. They all had to be elaborated at the cost of time and labour.""(J. Erik Jorpes ""Jac. Berzelius"", p.45).""In general Berzelius's efforts were directed toward the consolidation and extension of the atomic theory. He improved chemical analysis and determined the composition of a large number of compounds, thus verifying the laws of constant and multiple proportions and furnishing the most accurate equivalent weights then available. By ingenious methods he arrived at the correct atomic composition of most common substances, and thus was enabled to draw up (in 1826) a table of atomic weights very nearly identical with the modern one.""(Leicester & Klicktein ""A Source Book in Chemistry"", p. 258).Parkinson ""Breakthroughs"", 1810-20 C.‎

Library label pasted on to pasted down front free end-paper. Small library stamp to lower part of title title page and verso of title page. Very fine and clean. Pp.163-165 [Entire volume: IV, 575 pp.].‎

‎First printing of Lüroth's Theorem, a celebrated case of rational variety within algebraic variety. ""In 1876 he demonstrated the ""Lueroth theorem"", whereby each uni-rational curve in rational-Castelnuovo in 1895 proved the analogous but more difficul theorem for surfaces"" (DSB).Lüroth's problem concerns subextensions L of K(X), the rational functions in the single indeterminate X. Any such field is either equal to K or is also rational, i.e. L = K(F) for some rational function F. In geometrical terms this states that a non-constant rational map from the projective line to a curve C can only occur when C also has genus 0. That fact can be read off geometrically from the Riemann-Hurwitz formula.""In addition, Lueroth worked in other areas of mathematics far removed from algebraic geometry. He obtained partial proof of the topological in variance of dimension (proved in 1911 by L. Brouwer) and, following the work of Staudt, did research in complex geometry. He was also involved in the logical researches of his friend Schroder and published two books in applied mathematics and mechanics. These were Grundriss der Meclumik, in which he used the vector calculus for the first time* and Vorlesungen Uber immerisches Rechnen. Lueroth collaborated in editing the collected works of Hesse and Grassmann."" (DSB)‎

‎"RIIS, JACOB A.‎

‎How the Other Half Lives. Studies Among the Tenemants of New York. With Illustrations chiefly from Photographs taken by the Author. - [INITIATING SOCIAL REFORM]‎

‎New York, Charles Scribner's Sons, 1890. Lex 8vo. Original blue full clothWith title in blue to front board and blue and gilt lettering to spine. Spine and parts of boards lightly brownspotted. A bit of wear to capitaks and corners. But overall a very nice copy of this fairly fragile and delicate cloth binding (there is an original variant binding with cloth spine and illustrated boards, but no precidency between the bindings has been established). Internally very nice and clean. XV, (1), 304 pp. Wih numerous illustrations, most of them photographic.‎

‎First edition of this landmark work on the miserable living conditions of the poor immigrants in New York, constituting one of the very earliest - and certainly the most popular and influential - attempts at making ""the other half"", i.e. the middle and upper classes, aware of how the poor in New York actually lived. Riis's work created attention to the neglected and overseen community that was the underprivileged in New York. In the long run, the great success of the work created attention to the status, living conditions and general health of the poor, and it initiated social reform movements in all major North American cities. Furthermore, the work is regarded the very first example of ""muckraking"" journalism and was the first to extensively use halftone photographic reproductions in a book.Riis used a convincing combination of facts from Dr. Roger S. Tracy, Registrar of Vital Statistics, and his own talents as a photo journalist to make a hitherto unseen powerful description of the correlation between the high crime rate, drunkenness and reckless behavior of the poor and their lack of proper homes. The statistical facts made it a relevant and sober work and lent it enough authority to the book's claims for it to be taken serious by city official. His groundbreaking photographs confirmed the dry numbers and ""spoke directly to people's hearts"". (Pascal, ""Jacob Riis: Reporter and Reformer"", p. 87). Unlike all previously works on the living conditions of the poor, ""How the Other Half Lives"" offered concrete solutions on how to improve living condition, how to make the tenants improve their buildings, and finally how the politicians and city officials could make the appropriate and necessary juridical changes.The effect of the work was immediately seen and included: the tearing down of New York's worst tenements, sweatshops, and the reformation of the city's schools. The book led to a decade of improvements in Lower East Side conditions, with garbage collection, sewers, and indoor plumbing all following soon after. Because of the present work, Riis quickly rose to fame and in 1895 he became close friends with Theodore Roosevelt, then a New York City official, who wrote of Riis: ""Jacob Riis, whom I am tempted to call the best American I ever knew, although he was already a young man when he came hither from Denmark"". After Roosevelt became President, he wrote a tribute to Riis that started: ""Recently a man, well qualified to pass judgment, alluded to Mr. Jacob A. Riis as ""the most useful citizen of New York"". Those fellow citizens of Mr. Riis who best know his work will be most apt to agree with this statement. The countless evils which lurk in the dark corners of our civic institutions, which stalk abroad in the slums, and have their permanent abode in the crowded tenement houses, have met in Mr. Riis the most formidable opponent ever encountered by them in New York City.""The title refers to the French writer François Rabelais, who famously wrote in Pantagruel: ""one half of the world does not know how the other half lives"". As a work of journalism and of social criticism, Riis's book still stands as a truly seminal testimony to how the lower classes lived at the turn of the century. Due to this work, attention was eventually paid to them and their conditions bettered.‎
