Practical Astronomy with your Calculator, first published in 1979, has enjoyed immense success. The author's clear and easy to follow routines enable you to solve a variety of practical and recreational problems in astronomy using a scientific calculator. Mathematical complexity is kept firmly in the background, leaving just the elements necessary for swiftly making calculations. The major topics are: time, coordinate systems, the Sun, the planetary system, binary stars, the Moon, and eclipses. In the third edition there are entirely new sections on generalised coordinate transformations, nutrition, aberration, and selenographic coordinates. The calculations for sunrise and moonrise are improved. A larger page size has increased the clarity of the presentation. This handbook is essential for anyone who needs to make astronomical calculations. It will be enjoyed by amateur astronomers and appreciated by students studying introductory astronomy. • Clear presentation • Reliable approximations • Covers orbits, transformations, and general celestial phenomena • Can be used anywhere, worldwide • Routines extensively tested by thousands of readers round the world

Questo libro è nato dall'esperienza del corso di Matematica Generale all'Università Bocconi. Nel presentare gli oggetti matematici insegna allo studente l'utilizzo del calcolatore per svolgere calcolo numerico e calcolo simbolico, definire una funzione e calcolarne i valori, tracciare ed esplorare grafici, eseguire semplici algoritmi.La trattazione è ricca di esempi, applicazioni, modelli, tratti dal contesto economico ma anche da quello fisico, biologico, statistico e dalla stessa matematica. L'analisi di tali modelli costituisce in un certo senso il vero scopo della teoria matematica svolta.Per esplorare ed illustrare concetti e proprietà si fa largo uso di strumenti automatici di calcolo (software di Matematica, fogli elettronici). In particolare è stato utilizzato il software Mathcad®, sia come strumento di calcolo sia come semplice ma potente linguaggio di programmazione.Largo spazio è dedicato: all'approssimazione, sottolineando la distinzione tra calcolo numerico e calcolo simbolico; all'algoritmo come sintesi tra l'aspetto sintattico e quello semantico degli oggetti matematici; alla simulazione al calcolatore, interpretata come esperimento "fisico" e fonte di congetture. La possibilità di utilizzare un calcolatore sancisce una sorta di "democratizzazione" della matematica: risultati anche complessi, che hanno sempre richiesto un ampio retroterra di conoscenze e laboriosi calcoli, sono ora rapidamente raggiungibili da chiunque conosca il significato degli oggetti matematici e sappia usare la sintassi.

While computational technologies are transforming the professional practice of mathematics, as yet they have had little impact on school mathematics. This pioneering text develops a theorized analysis of why this is and what can be done to address it. It examines the particular case of symbolic calculators (equipped with computer algebra systems) in secondary education. Drawing on a substantial program of French innovation and research, as well as closely related studies from Australia and the Netherlands, it provides rich illustrations of the many aspects of technology integration, and of the ways in which these are shaped at different levels of the educational institution. This text offers the first English-language exposition of how an innovative synthesis of the theories of instrumentation and didactics can be used to illuminate the complexities of technology integration. It offers important guidance for policy and practice through its analysis of the central role of the teacher and its identification of key principles for effective didactical design and management. These distinctive features make this book essential reading for researchers, teacher educators, and graduate students in mathematics education and technology in education, as well as for teachers of mathematics at upper-secondary and university levels. This is a revised, English-language edition of D. Guin & L. Trouche (Eds.) (2002) Calculatrices symboliques. Transformer un outil en un instrument de travail mathématique: un problème didactique (Editions La Pensée Sauvage, Grenoble).
