Librairie Thomas-Scheler CEVA, Giovanni. De lineis rectis se invicem secantibus statica constructio. Mediolani, Ludovici Montiae, 1678. Edition originale. C'est l'ouvrage le plus important de Giovanni Ceva, mathématicien de Milan, dont Chasles parle avec beaucoup d'éloges. "The theorem of Menelaus concerning the segments produced by a transverse line of a triangle is proved, as is the transversal theorem concerning the currency of the transverse lines through the vertices of a triangle, which is named after Ceva. This theorem was established again by Johan I Bernoulli" (DSB). On trouve relié en tête : %D Edition originale. Casati (1617-1707) entra dans l'ordre des Jésuites et se consacra à l'enseignement des mathématiques. Son ouvrage, illustré de figures gravées sur bois dans le texte, est divisé en huit parties : centre de gravité, causes du mouvement des machines, treuils, poulies, etc. Bon exemplaire dans sa reliure d'origine, léger manque à la coiffe supérieure.

CTK Exchange Front Page Movie shortcuts Personal info ... Recommend this site Ceva's Theorem Giovanni Ceva (1648-1734) proved a theorem bearing his name that is seldom mentioned in Elementary Geometry courses. It's a regrettable fact because not only it unifies several other more fortunate statements but its proof is actually as simple as that of the less general theorems. Additionally, the general approach affords, as is often the case, rich grounds for further meaningful explorations. Ceva's Theorem In a triangle ABC, three lines AD, BE and CF intersect at a single point K if and only if (The lines that meet at a point are said to be concurrent Proof 1 Extend the lines BE and CF beyond the triangle until they meet GH, the line through A parallel to BC. There are several pairs of similar triangles: AHF and BCF, AEG and BCE, AGK and BDK, CDK and AHK. From these and in that order we derive the following proportions: AF/FB=AH/BC (*) CE/EA=BC/AG (*) AG/BD=AK/DK AH/DC=AK/DK from the last two we conclude that AG/BD = AH/DC and, hence, BD/DC = AG/AH (*).

35. The Italian Tradition Davanzati, 15291606. giovanni Botero, 1543-1617. giovanni ceva, 1647-1734- (1), (2), (3), (4) De lineis rectis, 1678; Opuscula mathematica http://cepa.newschool.edu/het/schools/italian.htm

The Italian Tradition This may look odd. Italian economists don't usually figure very prominently in histories of economic thought. Most people would probably only be able to name the giants Vilfredo Pareto and Piero Sraffa (both of whom were emigrants, incidentally). But Italy has had a very old and distinctive heritage in economics that is impossible to ignore. This distinctiveness emerged in the 18th Century, when Neapolitan economist, Ferdinando Galiani (1751) "broke off" from the main streams of Enlightenment economic thinking. He joined in the general reaction against Mercantilist thought, but he did not follow the path of the French Physiocratic and Scottish schools. Instead, Galiani initiated the two avenues which formed the "Italian tradition" in economics: the serious analysis of government as an economic entity and a utility-based theory of natural value. For Galiani, the economy must be analyzed more juridically than pseudo-scientifically. Government, he argued, is an important entity in any economy. It can, via its laws and fiscal policies, influence the economy and society for good and evil. Theories of the "natural state" without a State were, for him, hopelessly abstract and dangerously naive. The policy conclusions of the Physiocratic sect laissez-faire, laissez-passer

La Storia Continua Anno 1897 Nel lontano 12 Luglio del 1897, un gruppo di coraggiosi Ciclisti Italiani, copriva in tappa unica, la distanza di circa 230 Km. da Roma a Napoli, superando le avversità delle strade e condizioni dell'epoca, nascevano così i Brevetti Randonneurs , che col passar del tempo, andavano via via scomparendo dall'Italia, per prendere posto in Francia, sotto l'egida dell' Audax Club Parisien Anno 1997 Cento anni dopo, due uomini di paese, appassionati a questo tipo di Ciclismo, e intenzionati a riportare questi Brevetti in Italia, contattavano l' Audax , e venivano così invitati ad organizzare un Brevetto prova di 200 Km.. Anno 1998 Con lavoro e tenacia il 22 Maggio, il Brevetto prova di 200 Km., riusciva brillantemente, si veniva così autorizzati dall' Audax , ad organizzare anche in Italia, i Brevetti Randonneurs Mondiaux , indispensabili per la qualificazione alla Paris-Brest-Paris di Km. 1200, la più rinomata Manifestazione di lunga percorrenza del Mondo, in unica tappa e che si disputa ogni quattro anni, fino ad allora, solo due Italiani avevano portato a termine la P.B.P.
