Euler added his own supplements on ballistics, which were five times longer than the original text. These supplements occupy an important place in the history of ballistics...""

‎"BOLZANO, BERNARD.‎

‎Versuch einer objectiven Begründung der Lehre von den drei Dimensionen des Raumes. (Aus dem Abhandlungen der k. böhm. Gesellschaft der Wissenschaften (V Folge, Bd. 3).) - [BOLZANO'S FIRST WORK ON SPACE AND TIME]‎

‎Prag [Prague], 1843. 4to. Uncut in the original printed light pink wrappers, with a dicreet new black cloth back-strip. A bit of brownspotting and minor chipping to edges pf wrappers, but overall a very nice copy of this fairly fragile publication. 15, (1) pp.‎

‎The very rare first edition, off-print (separately paginated), of this important treatise on space and time, which constitutes an important part of Bolzano's philosophical-logical theory. The present paper constitutes the first public formulation of these controversial ideas on time and space, with which Bolzano sets out to establish a foundation of mathematics which is non-empirical. By uniting mathematics and philosophy and applying both to the question of space and time, Bolzano here brings both sciences to a higher level of completeness, acknowledging that his theories depart from the those of Hegel, Kant, Schelling, etc. As always, Bolzano grabs the essence of the question and the terms that he is treating and retraces the concepts that must be used, establishing their original inner connection. In the present paper, the question of space, time, and thought are treated in order to establish the precise and full nature of space, a theme which Bolzano had apparently been working on for many years but previously only discussed with a very small number of intimate acquaintances, and now publishes on for the first time. The concept of space plays an important rôle in Bolzano's ontology and is closely linked to his mathematical and philosophical logic, in which the ""space-position"" plays a part in the demarcation of that which is purely mathematical and logical. Furthermore, for Bolzano, truth is constituted by true propositions (which state things as they are), and his canonical form of all propositions entails that ""[a] proposition is true iff the object has the property (the attribute) which belongs to the subject of the proposition. Moreover, empirical propositions must contain determinations of space and time. Without these determinations, the sentence ""It is snowing"" has no truth value, it is just a propositional form which does not correspond to a complete proposition"" ""in order to be true, [such propositions] require the addition of such specifications as to time (and often place as well), 'It is snowing today, in this place'"" (SEP).‎

‎First edition of these 2 papers which unifies the Euclidean and Non-Euclidean geometries, by reducing the differences to expressions of the ""distance function"", and introducing the concepts ""parabolic"", ""elliptic"" and ""hyperbolic"" for the geometries of Euclid, Riemann and of Lobatschewski, Gauss and Bolyai. He further eliminates Euclid's parallel-axiom from projective geometry, as he shows that the quality of being parallel, is not invariant under projections.Klein build his work on Cayley's ""distant measure"" saying, that ""Metrical properties are not properties of the figure per se but of the figure in relation to the absolute."" This is Cayley's idea of the general projective determination of metrics. The place of the metric concept in projective geometry and the greater generality of the latter were described by Cayley as ""Metrical geometry is part of projective geometry."" Cayley's idea was taken over by Felix Klein....It seemed to him to be possible to subsume the non-Euclidean geometries, hyperbolic and double elliptic geometry, under projective geometry by exploring Cayley's idea. He gave a sketch of his thoughts in a paper of 1871, and then developed them in two papers (the papers offered here).Klein was the first to recognize that we do not need surfaces to obtain models of non-Euclidean geometries....The import which gradually emerged from Klein's contributions was that projective geometry is really logically independent of Euclidean geometry....By making apparent the basic role of projective geometry Klein paved the way for an axiomatic development which could start with projective geometry and derive the several metric geometries from it.""(Morris Kline).The offred volumes cntains other importen mathematical papers by f.i. by Klebsch, Lipschitz, Neumann, Noether, Thomae, Gordan, Lie, Du Bois-Raymond, Cantor (Über trigonometrische Reihen),etc.(Sommerville: Bibliography of Non-Euclidean Geometry p. 45 a. 49.)‎

‎Extremely scarce first edition of this comprehensive mathematical work, which was important in the spreading of the understanding of mathematical concepts. Johnn Rudolph von Graffenried, an encestor of Niklaus von Graffenried, was born in 1584. His great passion was the understanding of mathematical concepts, and in 1618-19 he published his main work ""Arithmeticae Logisticae"", in which he deals with the mathematical theories and theorems of Cardanus, Christoph Rudolf, Glarean, Schoner, Stiffel, Ramus, etc. The first part of the work deals with calculating with cardinal and broken numbers, the second with proportion, progression, etc., the third with calculation of interest, society, demography etc., and the fourth with decimal fractions.The general state of mathematics and the teaching of mathematics in Switzerland in the early 17th century was in a bad state, and Graffenried came to play a dominant role in the spreading and teaching of arithmetic in Switzerland, mainly through the present work.‎

‎Scarce first printings of these seminal papers, the first of which introduces Peirce's quincunical projection, the second of which documents his discovery of hitherto unknown diffraction phenomena called ""ghosts"".The Peirce quincuncial projection (published here for the first time) is a conformal map projection that presents the sphere as a square, which allowed for the displaying of the entire sphere with most areas being recognizable . Peirce called his projection quincuncial, after the arrangement of five items in a quincunx. ""For meteorological, magnetological and other purposes, it is convenient to have a projection of the sphere which shall show the connections of all parts of the surface."" Peirce himself wrote. (American Journal of Mathematics. Volume II. Number 4, 394 pp.)In ""On the Ghosts in Rutherfurd's Diffraction-Spectra"" Peirce documented his discovery of hitherto unknown diffraction phenomena called ""ghosts."" In his spectrum meter experiments, Peirce compared wave-lengths of light with the breadth of a diffraction plate. He used a machine called a comparator, a spectrometer he himself designed, and a diffraction plate designed by Lewis M. Rutherfurd.‎

‎First printing of this major paper in the founding of mathematical logic and pure mathematics. The paper offered here is a continuation of Boole's ""The Mathematical Analysis of Logic""(1847), pioneering the assimilation of logic to mathematics.Boole showed that how mathematical techniques could be applied to the study of logic, and as such he laid the foundations for the axiomatic and deductive treatment og logic, the Boolean algebra, which find imortent applications in both probability theory and computing. This mathematication of logic was undertaken by Frege and brought to a climax by Whitehead and Russell. Boolean algebra was used for this purpose.Boole's work contains what Bertrand Russell called the greatest discovery of the nineteenth century: the nature of pure mathematics.‎
