Book Description
An invaluable resource for working programmers, as well as a fount of useful algorithmic tools for computer scientists, astronomers, and other calendar enthusiasts, The Ultimate Edition updates and expands the previous edition to achieve more accurate results and present new calendar variants. The book now includes coverage of Unix dates, Italian time, the Akan, Icelandic, Saudi Arabian Umm al-Qura, and Babylonian calendars. There are also expanded treatments of the observational Islamic and Hebrew calendars and brief discussions of the Samaritan and Nepalese calendars. Several of the astronomical functions have been rewritten to produce more accurate results and to include calculations of moonrise and moonset. The authors frame the calendars of the world in a completely algorithmic form, allowing easy conversion among these calendars and the determination of secular and religious holidays. LISP code for all the algorithms is available in machine-readable form.

Scandalous Error
Author: C. Philipp E. Nothaft
Publisher: Oxford University Press
ISBN: 0198799551
Category : History
Languages : en
Pages : 378
Book Description
The Gregorian calendar reform of 1582, which provided the basis for the civil and Western ecclesiastical calendars still in use today, has often been seen as a triumph of early modern scientific culture or an expression of papal ambition in the wake of the Counter-Reformation. Much less attention has been paid to reform's intellectual roots in the European Middle Ages, when the reckoning of time by means of calendrical cycles was a topic of central importance to learned culture, as impressively documented by the survival of relevant texts and tables in thousands of manuscripts copied before 1500. For centuries prior to the Gregorian reform, astronomers, mathematicians, theologians, and even Church councils had been debating the necessity of improving or emending the existing ecclesiastical calendar, which throughout the Middle Ages kept losing touch with the astronomical phenomena at an alarming pace. Scandalous Error is the first comprehensive study of the medieval literature devoted to the calendar problem and its cultural and scientific contexts. It examines how the importance of ordering liturgical time by means of a calendar that comprised both solar and lunar components posed a technical-astronomical problem to medieval society and details the often sophisticated ways in which computists and churchmen reacted to this challenge. By drawing attention to the numerous connecting paths that existed between calendars and mathematical astronomy between the Fall of Rome and the end of the fifteenth century, the volume offers substantial new insights on the place of exact science in medieval culture.

The Jewish Calendar Controversy of 921/2 CE
Author: Sacha Stern
Publisher: BRILL
ISBN: 9004388672
Category : Science
Languages : en
Pages : 598
Book Description
In the year 921/2, the Jewish leaders of Palestine and Babylonia disagreed on how to calculate the calendar. This led the Jews of the entire Near East to celebrate Passover and the other festivals, through two years, on different dates. The controversy was major, but it became forgotten until its late 19th-century rediscovery in the Cairo Genizah. Faulty editions of the texts, in the following decades, led to much misunderstanding about the nature, leadership, and aftermath of the controversy. In this book, Sacha Stern re-edits the texts completely, discovers many new Genizah sources, and challenges the historical consensus. This book sheds light on early medieval Rabbanite leadership and controversies, and on the processes that eventually led to the standardization of the medieval Jewish calendar.

The Algorithm Design Manual
Author: Steven S Skiena
Publisher: Springer Science & Business Media
ISBN: 1848000707
Category : Computers
Languages : en
Pages : 742
Book Description
This newly expanded and updated second edition of the best-selling classic continues to take the "mystery" out of designing algorithms, and analyzing their efficacy and efficiency. Expanding on the first edition, the book now serves as the primary textbook of choice for algorithm design courses while maintaining its status as the premier practical reference guide to algorithms for programmers, researchers, and students. The reader-friendly Algorithm Design Manual provides straightforward access to combinatorial algorithms technology, stressing design over analysis. The first part, Techniques, provides accessible instruction on methods for designing and analyzing computer algorithms. The second part, Resources, is intended for browsing and reference, and comprises the catalog of algorithmic resources, implementations and an extensive bibliography. NEW to the second edition: • Doubles the tutorial material and exercises over the first edition • Provides full online support for lecturers, and a completely updated and improved website component with lecture slides, audio and video • Contains a unique catalog identifying the 75 algorithmic problems that arise most often in practice, leading the reader down the right path to solve them • Includes several NEW "war stories" relating experiences from real-world applications • Provides up-to-date links leading to the very best algorithm implementations available in C, C++, and Java

The Holocaust's Jewish Calendars
Author: Alan Rosen
Publisher: Indiana University Press
ISBN: 0253038286
Category : Religion
Languages : en
Pages : 272
Book Description
“The most comprehensive to date treatment of these precious artifacts of the Holocaust’s Jewish efforts to maintain religious observations and identity.” —Choice Calendars map time, shaping and delineating our experience of it. While the challenges to tracking Jewish conceptions of time during the Holocaust were substantial, Alan Rosen reveals that many took great risks to mark time within that vast upheaval. Rosen inventories and organizes Jewish calendars according to the wartime settings in which they were produced—from Jewish communities to ghettos and concentration camps. The calendars he considers reorient views of Jewish circumstances during the war and show how Jews were committed to fashioning traditional guides to daily life, even in the most extreme conditions. In a separate chapter, moreover, he elucidates how Holocaust-era diaries sometimes served as surrogate Jewish calendars. All in all, Rosen presents a revised idea of time, continuity, the sacred and the mundane, the ordinary and the extraordinary even when death and destruction were the order of the day. Rosen’s focus on the Jewish calendar—the ultimate symbol of continuity, as weekday follows weekday and Sabbath follows Sabbath—sheds new light on how Jews maintained connections to their way of conceiving time even within the cauldron of the Holocaust. “Rosen demonstrates the relationship between time and meaning, between meaning and holiness, between holy days and the divine presence―all of which came under assault in the Nazis’ effort to kill Jewish souls before destroying Jewish bodies.” —David Patterson, author of Along the Edge of Annihilation: The Collapse and Recovery of Life in the Holocaust Diary
