Objects in harmonic motion have the ability to transfer some of their energy over large distances. Light Nature: This chapter covers the nature of light, polarization, and color.

    The Big Bang Cosmology is explored, looking at its observational successes in explaining the expansion of the Universe, the existence and properties of the cosmic microwave background, and the origin of light elements in the universe. Properties of the very early Universe are also covered, including the motivation for a rapid period of expansion known as cosmological inflation. The third edition brings this established undergraduate textbook up-to-date with the rapidly evolving observational situation. This fully revised edition of a bestseller takes an approach which is grounded in physics with a logical flow of chapters leading the reader from basic ideas of the expansion described by the Friedman equations to some of the more advanced ideas about the early universe. It also incorporates up-to-date results from the Planck mission, which imaged the anisotropies of the Cosmic Microwave Background radiation over the whole sky. The Advanced Topic sections present subjects with more detailed mathematical approaches to give greater depth to discussions. Student problems with hints for solving them and numerical answers are embedded in the chapters to facilitate the reader's understanding and learning. Cosmology is now part of the core in many degree programs. This current, clear and concise introductory text is relevant to a wide range of astronomy programs worldwide and is essential reading for undergraduates and Masters students, as well as anyone starting research in cosmology.

    The fully articulated skeleton of a female saint, dressed in an intricate costume of silk brocade and gold lace, withered fingers glittering with colorful rubies, emeralds, and pearls this is only one of the specially photographed relics featured in Heavenly Bodies. In 1578 news came of the discovery in Rome of a labyrinth of underground tombs, which were thought to hold the remains of thousands of early Christian martyrs. Skeletons of these supposed saints were subsequently sent to Catholic churches and religious houses in German-speaking Europe to replace holy relics that had been destroyed in the wake of the Protestant Reformation. The skeletons, known as the catacomb saints, were carefully reassembled, richly dressed in fantastic costumes, wigs, crowns, jewels, and armor, and posed in elaborate displays inside churches and shrines as reminders to the faithful of the heavenly treasures that awaited them after death. Paul Koudounaris gained unprecedented access to religious institutions to reveal these fascinating historical artifacts. Hidden for over a century as Western attitudes toward both the worship of holy relics and death itself changed, some of these ornamented skeletons appear in publication here for the first time."

    Here is the definitive guide to the geography of Middle-earth, from its founding in the Elder Days through the Third Age, including the journeys of Bilbo, Frodo, and the Fellowship of the Ring. Authentic and updated -- nearly one third of the maps are new, and the text is fully revised -- the atlas illuminates the enchanted world created in THE SILMARILLION, THE HOBBIT, and THE LORD OF THE RINGS.Hundreds of two-color maps and diagrams survey the journeys of the principal characters day by day -- including all the battles and key locations of the First, Second, and Third Ages. Plans and descriptions of castles, buildings, and distinctive landforms are given, along with thematic maps describing the climate, vegetation, languages, and population distribution of Middle-earth throughout its history. An extensive appendix and an index help readers correlate the maps with Tolkien's novels.

    Bell, a leading figure in mathematics in America for half a century. Men of Mathematics accessibly explains the major mathematics, from the geometry of the Greeks through Newton's calculus and on to the laws of probability, symbolic logic, and the fourth dimension. In addition, the book goes beyond pure mathematics to present a series of engrossing biographies of the great mathematicians -- an extraordinary number of whom lived bizarre or unusual lives. Finally, Men of Mathematics is also a history of ideas, tracing the majestic development of mathematical thought from ancient times to the twentieth century. This enduring work's clear, often humorous way of dealing with complex ideas makes it an ideal book for the non-mathematician.

    He begins with Copernicus, during the Renaissance, when science replaced mysticism as a means of explaining the workings of the world, and he continues through the centuries, creating an unbroken genealogy of not only the greatest but also the more obscure names of Western science, a dot-to-dot line linking amateur to genius, and accidental discovery to brilliant deduction.By focusing on the scientists themselves, Gribbin has written an anecdotal narrative enlivened with stories of personal drama, success and failure. A bestselling science writer with an international reputation, Gribbin is among the few authors who could even attempt a work of this magnitude. Praised as “a sequence of witty, information-packed tales” and “a terrifi c read” by The Times upon its recent British publication, The Scientists breathes new life into such venerable icons as Galileo, Isaac Newton, Albert Einstein and Linus Pauling, as well as lesser lights whose stories have been undeservedly neglected. Filled with pioneers, visionaries, eccentrics and madmen, this is the history of science as it has never been told before.From the Hardcover edition.
