Download or read book The Mathematics of the Gregorian Calendar written by David Braverman and published by Xlibris Corporation. This book was released on 2009-10-30 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of this book is based on codes assigned to each month of the year, to each year and to each century. Since Pope Gregory XIII replaced the Julian calendar with the Gregorian calendar on February 24, 1582, (and I don't know if he named after himself), the calendar has followed a cycle that makes it predictable. That's where you and I come in. The mathematics is based on an easily learned system called Modulo 7. The problems involve dates and are based an equation with involving 4 quantities. One of them will be unknown. In Task A, that will be the day of the week. If a carnival had a wheel with a spinner that had the 7 days of the week on them, wherever the spinner stops MUST be a day of the week. That is essentially modulo 7. There are no fractions. There are just seven numbers. Readers should know multiples of 7 to avoid having to look at the table.
Download or read book The Mathematics of the Calendar written by Marc Cohn and published by Lulu.com. This book was released on 2007-07-29 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will explain the mathematical details behind the Jewish calendar and Easter calculation with a mathematical proposal to fix the Jewish Calendar from an actuary.In addition, we will explore the mathematics behind the Mayan calendar, Islamic calendar, and our everyday calendar, the Gregorian calendar. First, I will demonstrate how the Jewish calendar works, and how to convert dates between the Jewish calendar to the Gregorian/Julian calendar. I will then explain the Easter calculation and demonstrate how to use the methods from the Easter calculation to fix the Jewish calendar so that the Jewish calendar stays consistent with the solar cycle. In 1582, there were two competing proposals to reform the Julian calendar. I will explain the mathematics behind the two proposals. I will explain the proposal that placed Washington, DC on the 77th meridian.

Book excerpt: In 1995, Mark Silen was playing around with simple math and working with calendars when he stumbled upon something so amazing that he began to question nearly everything he had ever been taught. In The Perfect Time: The Universal Calendar, Silen shares the results of his research into one of the biggest coincidences in historythat man could have potentially missed the perfect measurement of time by one day. Never in a million years did Silen think that seven numberstwo easy addition equations and six simple multiplication equationswould apply to so many disciplines, but as he began to create his Universal Calendar, he realized that many issues in religion, mathematics, science, and history could have been forever affected by the use of these seven, perfect numbers. As Silen shares an easy-to-understand system based on common knowledge and logic, he questions why we are still using a calendar system today that was created by people who thought the earth was flat. The fascinating system behind The Perfect Time: The Universal Calendar illustrates all the reasons why a new, more simplistic calendar could have a major impact on todays society and have more meaning than any other calendar in history.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Mathematics Elsewhere written by Marcia Ascher and published by Princeton University Press. This book was released on 2018-06-05 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematics Elsewhere is a fascinating and important contribution to a global view of mathematics. Presenting mathematical ideas of peoples from a variety of small-scale and traditional cultures, it humanizes our view of mathematics and expands our conception of what is mathematical. Through engaging examples of how particular societies structure time, reach decisions about the future, make models and maps, systematize relationships, and create intriguing figures, Marcia Ascher demonstrates that traditional cultures have mathematical ideas that are far more substantial and sophisticated than is generally acknowledged. Malagasy divination rituals, for example, rely on complex algebraic algorithms. And some cultures use calendars far more abstract and elegant than our own. Ascher also shows that certain concepts assumed to be universal--that time is a single progression, for instance, or that equality is a static relationship--are not. The Basque notion of equivalence, for example, is a dynamic and temporal one not adequately captured by the familiar equal sign. Other ideas taken to be the exclusive province of professionally trained Western mathematicians are, in fact, shared by people in many societies. The ideas discussed come from geographically varied cultures, including the Borana and Malagasy of Africa, the Tongans and Marshall Islanders of Oceania, the Tamil of South India, the Basques of Western Europe, and the Balinese and Kodi of Indonesia. This book belongs on the shelves of mathematicians, math students, and math educators, and in the hands of anyone interested in traditional societies or how people think. Illustrating how mathematical ideas play a vital role in diverse human endeavors from navigation to social interaction to religion, it offers--through the vehicle of mathematics--unique cultural encounters to any reader.
