This book is intended to serve as a one-semester introductory course in number theory. Throughout the book a historical perspective has been adopted and emphasis is given to some of the subject's applied aspects; in particular the field of cryptography is highlighted. At the heart of the book are the major number theoretic accomplishments of Euclid, Fermat, Gauss, Legendre, and Euler, and to fully illustrate the properties of numbers and concepts developed in the text, a wealth of exercises have been included. It is assumed that the reader will have 'pencil in hand' and ready access to a calculator or computer. For students new to number theory, whatever their background, this is a stimulating and entertaining introduction to the subject.
This book brings together for the first time 140 letters from Sylvester's correspondence in an attempt to separate the fact from the many myths surrounding his life and work --
This update to the award-winning The Origins of Modern Humans: A World Survey of the Fossil Evidence covers the most accepted common theories concerning the emergence of modern Homo sapiens adding fresh insight from top young scholars on the key new discoveries of the past 25 years. The Origins of Modern Humans: Biology Reconsidered allows field leaders to discuss and assess the assemblage of hominid fossil material in each region of the world during the Pleistocene epoch. It features new fossil and molecular evidence, such as the evolutionary inferences drawn from assessments of modern humans and large segments of the Neandertal genome. It also addresses the impact of digital imagery and the more sophisticated morphometrics that have entered the analytical fray since 1984. Beginning with a thoughtful introduction by the authors on modern human origins, the book offers such insightful chapter contributions as: Africa: The Cradle of Modern People Crossroads of the Old World: Late Hominin Evolution in Western Asia A River Runs through It: Modern Human Origins in East Asia Perspectives on the Origins of Modern Australians Modern Human Origins in Central Europe The Makers of the Early Upper Paleolithic in Western Eurasia Neandertal Craniofacial Growth and Development and Its Relevance for Modern Human Origins Energetics and the Origin of Modern Humans Understanding Human Cranial Variation in Light of Modern Human Origins The Relevance of Archaic Genomes to Modern Human Origins The Process of Modern Human Origins: The Evolutionary and Demographic Changes Giving Rise to Modern Humans The Paleobiology of Modern Human Emergence Elegant and thought provoking, The Origins of Modern Humans: Biology Reconsidered is an ideal read for students, grad students, and professionals in human evolution and paleoanthropology.
A fact-filled, illustrated exhibit of four billion years of history in 133 objects—from Pangaea to ancient Rome to Dracula’s home to the iPhone. This amazing book tells the story of our planet as you’ve never seen it before. The Mini Museum is a collection of treasures gathered from across space and time and shared by tens of thousands of people in more than 120 countries. Each item in the collection is inspired by a childhood dream of sharing all the wonders the universe has to offer while bringing all of us closer together. In this book, the Mini Museum team shares the stories of real objects that have shaped our very existence across billions of years of history. Beginning with the birth of our solar system and the very building blocks of life, you’ll explore our dynamic planet, from the constant shifting of continents to dramatic and violent upheavals that have changed the course of all life again and again. You’ll visit mighty civilizations with cultures spanning millennia, as well as modern symbols of creativity and innovation, and the march of humanity as we reach toward the stars. Every item is photographed and presented in detail—and there are also wild tales of adventure as the crew travels the world and prepares one of the most complex collections ever assembled.
