5000 Years of Geometry
Author: Christoph J. ScribaPublisher: Birkhäuser
ISBN: 3034808984
Category : Mathematics
Languages : en
Pages : 638
Book Description
The present volume provides a fascinating overview of geometrical ideas and perceptions from the earliest cultures to the mathematical and artistic concepts of the 20th century. It is the English translation of the 3rd edition of the well-received German book “5000 Jahre Geometrie,” in which geometry is presented as a chain of developments in cultural history and their interaction with architecture, the visual arts, philosophy, science and engineering. Geometry originated in the ancient cultures along the Indus and Nile Rivers and in Mesopotamia, experiencing its first “Golden Age” in Ancient Greece. Inspired by the Greek mathematics, a new germ of geometry blossomed in the Islamic civilizations. Through the Oriental influence on Spain, this knowledge later spread to Western Europe. Here, as part of the medieval Quadrivium, the understanding of geometry was deepened, leading to a revival during the Renaissance. Together with parallel achievements in India, China, Japan and the ancient American cultures, the European approaches formed the ideas and branches of geometry we know in the modern age: coordinate methods, analytical geometry, descriptive and projective geometry in the 17th an 18th centuries, axiom systems, geometry as a theory with multiple structures and geometry in computer sciences in the 19th and 20th centuries. Each chapter of the book starts with a table of key historical and cultural dates and ends with a summary of essential contents of geometr y in the respective era. Compelling examples invite the reader to further explore the problems of geometry in ancient and modern times. The book will appeal to mathematicians interested in Geometry and to all readers with an interest in cultural history. From letters to the authors for the German language edition I hope it gets a translation, as there is no comparable work. Prof. J. Grattan-Guinness (Middlesex University London) "Five Thousand Years of Geometry" - I think it is the most handsome book I have ever seen from Springer and the inclusion of so many color plates really improves its appearance dramatically! Prof. J.W. Dauben (City University of New York) An excellent book in every respect. The authors have successfully combined the history of geometry with the general development of culture and history. ... The graphic design is also excellent. Prof. Z. Nádenik (Czech Technical University in Prague)
LSD, My Problem Child
Author: Albert HofmannPublisher: Multidisciplinary Association for Psychedelic Studies
ISBN: 9780979862229
Category : Body, Mind & Spirit
Languages : en
Pages : 224
Book Description
This is the story of LSD told by a concerned yet hopeful father, organic chemist Albert Hofmann, Ph.D. He traces LSD's path from a promising psychiatric research medicine to a recreational drug sparking hysteria and prohibition. In LSD: My Problem Child, we follow Dr. Hofmann's trek across Mexico to discover sacred plants related to LSD, and listen in as he corresponds with other notable figures about his remarkable discovery. Underlying it all is Dr. Hofmann's powerful conclusion that mystical experiences may be our planet's best hope for survival. Whether induced by LSD, meditation, or arising spontaneously, such experiences help us to comprehend "the wonder, the mystery of the divine, in the microcosm of the atom, in the macrocosm of the spiral nebula, in the seeds of plants, in the body and soul of people." More than sixty years after the birth of Albert Hofmann's problem child, his vision of its true potential is more relevant, and more needed, than ever.

Rabdology

Category : Computers

Pages : 184
Book Description
This first English translation of Napier's Rabdologia provides a clear and readable introduction to a group of physical calculating devices, which, long overshadowed by Napier's logarithms, have their own intrinsic interest and charm. "The tasks which fill'd beginners with dismayThis little book has banish'd clear away." John Napier had already discovered and published an epochmaking treatise on logarithms when in 1617 he turned to "rabdology" or rod-reckoning as yet another means by which to confront the problem of simplifying the huge calculations involved in multiplication, division, and the extraction of roots. This first English translation of Napier's Rabdologia provides a clear and readable introduction to a group of physical calculating devices, which, long overshadowed by Napier's logarithms, have their own intrinsic interest and charm. Book I describes the first device, a set of rods known as "Napier's Bones," which were inscribed with numbers forming multiplication tables and used in conjunction with pencil and paper. Book 11 presents a series of simple calculations that readers can solve by using the rods, and a series of tables of ratios useful for division. Napier then describes the second mechanical device for calculation, a forerunner of the modern calculator that he named promptuary or "place where things are stored ready for use." The third device, similar to a chessboard, allowed calculations to be performed by moving counters around the squares. Observing that the numbers had to be represented in what would now be called binary form, Napier provides instructions for changing from ordinary to binary numbers and back again, a method that worked equally well for multiplication and division and that had a particularly elegant symmetry when applied to the extraction of square roots.
Mathematics Unbound: The Evolution of an International Mathematical Research Community, 1800-1945
Author: Karen Hunger ParshallPublisher: American Mathematical Soc.
ISBN: 0821821245
Category : Mathematics
Languages : en
Pages : 430
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.

A History of Western Astrology
Author: S. J. TesterPublisher: Boydell & Brewer Ltd
ISBN: 9780851152554
Category : Art
Languages : en
Pages : 274
Book Description
Superb general account.' Times Literary Supplement The story of the history of Western astrology begins with the philosophers of Greece in the 5th century BC. To the magic and stargazing of Egypt the Greeks added numerology, geometryand rational thought. The philosophy of Plato and later of the Stoics made astrology respectable, and by the time Ptolemy wrote his textbook the Tetrabiblos, in the second century AD, the main lines of astrological practice as it is known today had already been laid down. In future centuries astrology shifted to Islam only to return to the West in medieval times where it flourished until the shift of ideas during the Renaissance.
