Selecciones de Matematicas Aplicadas


Book Description

Selecciones de matemáticas aplicadas es un puente entre las matemáticas básicas y las matemáticas superiores. El libro comienza con una revisión de las matemáticas básicas: la numerología, la aritmética, el álgebra, la geometría euclidiana, la trigonometría, y los logaritmos. En las lecciones intermedias, se estudian las funciones lineales, cuadradas, cubicas, exponenciales e hiperbólicas. En las lecciones finales, se examinan el cálculo diferencial e integral, la teoría de las probabilidades, la teoría cuántica, las teorías de la relatividad, y las teorías de caos y la complejidad. Entre las aplicaciones más destacadas, citamos algunos ejemplos: El crecimiento exponencial de las bacterias en los medios de cultivo, el crecimiento de los capitales en el interés compuesto, el crecimiento exponencial de los números de transistores en los últimos 30 años de la tecnología moderna, la reducción exponencial de los virus del SIDA en los pacientes tratados con cocteles de drogas antivirales, y las probabilidades en los juegos del “craps”, y del póker.

Subject Headings for School and Public Libraries


Book Description

For public and school libraries, this resource reflects recent changes in Library of Congress subject headings and authority files, and provides bilingual information essential to reference librarians and catalogers serving Spanish speakers. Libraries must provide better access to their collections for all users, including Spanish-language materials. The American Library Association has recognized this increasing need. Subject Headings for School and Public Libraries: Bilingual Fourth Edition is the only resource available that provides both authorized and reference entries in English and Spanish. A first-check source for the most frequently used headings needed in school and public libraries, this book incorporates thousands of new and revised entries to assist in applying LCSH and CSH headings. Of the approximately 30,000 headings listed, most include cross-references, and all of the cross-reference terms are translated. MARC21 tags are included for all authorized entries to simplify entering them into computerized catalogs, while indexes to all headings and free-floating subdivisions are provided in translation from Spanish to English. This book gives librarians access to accurate translations of the subject terms printed in books published and cataloged in English-speaking countries—invaluable information in settings with Spanish-speaking patrons.




Mathematics Unbound: The Evolution of an International Mathematical Research Community, 1800-1945


Book Description

Although today's mathematical research community takes its international character very much for granted, this ``global nature'' is relatively recent, having evolved over a period of roughly 150 years-from the beginning of the nineteenth century to the middle of the twentieth century. During this time, the practice of mathematics changed from being centered on a collection of disparate national communities to being characterized by an international group of scholars for whom thegoal of mathematical research and cooperation transcended national boundaries. Yet, the development of an international community was far from smooth and involved obstacles such as war, political upheaval, and national rivalries. Until now, this evolution has been largely overlooked by historians andmathematicians alike. This book addresses the issue by bringing together essays by twenty experts in the history of mathematics who have investigated the genesis of today's international mathematical community. This includes not only developments within component national mathematical communities, such as the growth of societies and journals, but also more wide-ranging political, philosophical, linguistic, and pedagogical issues. The resulting volume is essential reading for anyone interestedin the history of modern mathematics. It will be of interest to mathematicians, historians of mathematics, and historians of science in general.
