From these observations he developed his Tychonic system of the universe-- a highly original, if incorrect, scheme that attempted to reconcile the ancient belief that the Earth stood still with Nicolaus Copernicus's revolutionary rearrangement of the solar system some fifty years earlier. Tycho knew that Kepler, the brilliant young mathematician he had engaged to interpret his findings, believed in Copernicus's arrangement, in which all the planets circled the Sun; and he was afraid his system-- the product of a lifetime of effort to explain how the universe worked-- would be abandoned.In point of fact, it was. From his study of Tycho's observations came Kepler's stunning three Laws of Planetary Motion-- ever since the cornerstone of cosmology and our understanding of the heavens. Yet, as Kitty Ferguson reveals, neither of these giant figures would have his reputation today without the other. The story of how their lives and talents were fatefully intertwined is one of the more memorable sagas in the long history of science.Set in a singularly turbulent and colorful era in European history, at the turning point when medieval gave way to modern, Tycho & Kepler is both a highly original dual biography and a masterful recreation of how science advances. From Tycho's fabulous Uraniborg Observatory on an island off the Danish coast to the court of the Holy Roman Emperor, Rudolph II; from the religious conflict of the Thirty Years' War that rocked all of Europe to Kepler's extraordinary leaps of understanding, Ferguson recounts a fascinating interplay of science and religion, politics and personality. Her insights recolor the established characters of Tycho and Kepler, and her book opens a rich window onto our place in the universe.

      In the constellation of Eridanus, there lurks a cosmic mystery: It’s as if something has taken a huge bite out of the universe. But what is the culprit? The hole in the universe is just one of many puzzles keeping cosmologists busy. Supermassive black holes, bubbles of nothingness gobbling up space, monster universes swallowing others—these and many other bizarre ideas are being pursued by scientists. Due to breathtaking progress in astronomy, the history of our universe is now better understood than the history of our own planet. But these advances have uncovered some startling riddles. In this electrifying new book, renowned cosmologist and author Paul Davies lucidly explains what we know about the cosmos and its enigmas, exploring the tantalizing—and sometimes terrifying—possibilities that lie before us. As Davies guides us through the audacious research offering mind-bending solutions to these and other mysteries, he leads us up to the greatest outstanding conundrum of all: Why does the universe even exist in the first place? And how did a system of mindless, purposeless particles manage to bring forth conscious, thinking beings? Filled with wit and wonder, What’s Eating the Universe? is a dazzling tour of cosmic questions, sure to entertain, enchant, and inspire us all.

    And everything changes.While Róisín grew up in a tiny village in Ireland, ablaze with a passion for science and the skies and for all there is to discover about the world, François was raised by his beautiful young mother, who dreamt of new worlds but was unable to turn her back on her past.As we loop back through their lives, glimpsing each of them only when a comet is visible in the skies above, we see how their paths cross as they come closer and closer to this moment.Theirs are stories filled with love and hope and heartbreak, that show how strangers can be connected and ghosts can be real, and the world can be as lonely or as beautiful as the comets themselves.

    Mark Hodkinson's biography of Queen focuses on the band's formative years, and draws on interviews with over sixty friends and colleagues of Freddie Mercury, Brian May, Roger Taylor and John Deacon.

    A number of the key figures in the new edition are revised to provide a more inviting and informative treatment. The figures are broken into component parts with supporting commentary so that they can more readily see the key ideas. Material from The Flying Circus is incorporated into the chapter opener puzzlers, sample problems, examples and end-of-chapter problems to make the subject more engaging. Checkpoints enable them to check their understanding of a question with some reasoning based on the narrative or sample problem they just read. Sample Problems also demonstrate how engineers can solve problems with reasoned solutions.

    The first half of the book deals with classical physical optics; the second principally with the quantum nature of light. Chapters 1 and 2 treat the propagation of light waves, including the concepts of phase and group velocities, and the vectorial nature of light. Chapter 3 applies the concepts of partial coherence and coherence length to the study of interference, and Chapter 4 takes up multiple-beam interference and includes Fabry-Perot interferometry and multilayer-film theory. Diffraction and holography are the subjects of Chapter 5, and the propagation of light in material media (including crystal and nonlinear optics) are central to Chapter 6. Chapters 7 and 8 introduce the quantum theory of light and elementary optical spectra, and Chapter 9 explores the theory of light amplification and lasers. Chapter 10 briefly outlines ray optics in order to introduce students to the matrix method for treating optical systems and to apply the ray matrix to the study of laser resonators.Many applications of the laser to the study of optics are integrated throughout the text. The author assumes students have had an intermediate course in electricity and magnetism and some advanced mathematics beyond calculus. For classroom use, a list of problems is included at the end of each chapter, with selected answers at the end of the book.

    While maintaining the hallmark features of previous editions, the Fourth Edition has been completely updated.

     From a polar bear who fished the Thames nightly for his dinner to elephants who drank only wine, the inhabitants of the southwest corner of the Tower of London were a strange and rowdy bunch. No less strange was the cast of characters that visited them: William Blake, Chaucer, and Samuel Pepys, to name a few. Daniel Hahn's fascinating history of the Tower of London's Royal Menagerie tells the story of the thousands of exotic creatures who found a home in one of the world's most forbidding and infamous fortresses. The Royal Menagerie began with a wedding gift: three leopards from King Henry III's new brother-in-law, Frederick the Holy Roman Emperor, in 1235. Soon after, a huge Norwegian polar bear joined them. Over the next six hundred years, the Tower played host to lions, ostriches, elephants, and other unusual animals that astonished London. Brimming with unforgettable stories (the lion who kept a spaniel as a pet; ostriches who were fed a steady diet of rusty nails; lions who, their keepers claimed, could tell whether a woman was a virgin) and beautiful historical illustrations, The Tower Menagerie provides an intriguing, lively survey of our changing attitudes toward animals, as well as a hugely entertaining journey through six centuries of British history.

    As a pragmatic, hands-on guide for beginning to intermediate hobbyists, The Conscientious Marine Aquarist demystifies the process of planning, setting up, stocking, and managing a beautiful, thriving slice of the tropical ocean. A leading advocate for the responsible collection and care of wild-caught specimens, Fenner starts with the basics -- "What is a fish?" -- and proceeds to give the reader the scientific background and expert-level secrets to being a smarter consumer, better steward, and more successful marine aquarium keeper.

    With all its traditional enemies no longer threatening, it was becoming redundant. Then the aliens arrived, warning of others behind them, not so friendly and massing for attack.

    Elsewhere, a team of scientists transverses the tundra, sleeping in tents, surviving on frozen chocolate, and measuring the snow every ten kilometers in a quest to understand the effects of albedo, the snow's reflective ability to cool the earth beneath it.Climate change isn't an abstraction in the far North. It is a reality that has already dramatically altered daily life, especially that of the native peoples who still live largely off the land and sea. Because nature shows her footprints so plainly here, the region is also a lure for scientists intent on comprehending the complexities of climate change. In this gripping account, Charles Wohlforth follows the two groups as they navigate a radically shifting landscape. The scientists attempt to decipher its smallest elements and to derive from them a set of abstract laws and models. The natives draw on uncannily accurate traditional knowledge, borne of long experience living close to the land. Even as they see the same things-a Native elder watches weather coming through too fast to predict; a climatologist notes an increased frequency of cyclonic systems-the two cultures struggle to reconcile their vastly different ways of comprehending the environment.With grace, clarity, and a sense of adventure, Wohlforth--a lifelong Alaskan--illuminates both ways of seeing a world in flux, and in the process, helps us to navigate a way forward as climate change reaches us all.
