    Description:

    "This volume is a must for anyone interested in academic problems and will produce the emotion of recognition in those concerned, and the emotion of surprise in those outside the field."-Los Angeles Times "Professors Caplow and McGee have given scholarly respectability to what many a professor has long suspected: Competition in the academic marketplace is as severe as in the business world. [Their book] might come to have the same function for the professor as Machiavelli’s work had for ambitious princes."-Midwest Journal of Political Science The Academic Marketplace is a straightforward, hard-hitting exposu of the American university. Caplow and McGee consider all the working parts of the system and assess their suitability to the professed purpose. Their report on the actualities, myths, and consequences of routines thus amounts to an anatomy of an institution-an anatomy that does not present a pretty picture. We learn, for example, that the chief criteria used in making appointments are prestige and compatibility, not teaching ability. The authors describe the precipitous decline in teaching loads and then explain how this tendency is related to the new seller’s market, on the one hand, and to the extravagantly indeterminate structure of the university as an institution, on the other. Not only is the temper judicious, the facts well gathered and competently marshaled, but the expression of results is invariably lucid. In a new introduction, the authors sort out fact from legend and discern trends, they address the validity of their own research methods and the applicability of their original findings to today’s academic marketplace. They observe that the essential commodity offered in the academic marketplace is still the same-the mysterious intangible called prestige, by which universities, colleges, departments, disciplines, fields of inquiry, journals, and ultimately faculty candidates are ranked from high to low, and raised up and cast down accordingly.

    Title: From Here to Infinity
    Author: Andrea Del Centina
    Language: English
    Year: 2025
    Subjects: History, Mathematics, Nonfiction
    Publisher: Springer, Berlin, Springer Nature Switzerland, Springer
    ISBN: 3031725840
    Total pages: 820

    Description:

    This monograph traces the development of projective geometry from its Greek origins to the early 20th century. It covers Renaissance perspective studies and insights from the late sixteenth to seventeenth centuries, examining the contributions of Desargues and Pascal.
    Most of the book is devoted to the evolution of the subject in the 19th century, from Carnot to von Staudt. In particular, the book offers an unusually thorough appreciation of Brianchon’s work, a detailed study of Poncelet’s innovations, and a remarkable account of the contributions of Möbius and Plücker. It also addresses the difficult question of the historical relationship between synthetic and analytic points of view in geometry, analyzing the work of prominent synthetic geometers Steiner, Chasles, and von Staudt in detail. The book concludes around 1930, after the synthetic point of view was axiomatized and the analytic point of view became intertwined with algebraic geometry.
    Balancing historical analysis with technical precision and providing deep insights into the evolution of the mathematics, this richly illustrated book serves as a central reference on the history of projective geometry.
