The world as it is viewed from modern physics and cosmology has many strange and unexpected features. Often these are in stark contrast with our everyday experience or our preconceptions, such as the concept of space and time as finite and changeable. Nevertheless it is this strange world which is the fundamental basis of our existence. Therefore modern science also has a few things to say about the age-old questions: Who are we? Where do we come from? Where are we going?

The author, an experienced scientist and teacher, presents the knowledge that we have about our worldfor non-experts. He takes us on a journey through cosmology and the quantum world of elementary particles. And he sketches the impact of the insights gained into philosophical assumptions and religious beliefs in these disciplines. In the end he asks the speculative question whether there is something beyond the limits of the natural sciences.

Grating Spectroscopes and How to Use Them is written for amateur astronomers who are just getting into this field of astronomy. Transmission grating spectroscopes look like simple filters and are designed to screw into place on the eyepiece of a telescope for visual use, or into the camera adapter for digicam or CCD imaging. Using the most popular commercially made filter gratings - Rainbow Optics (US) and Star Analyzer (UK) - as examples, this book provides the reader with information on how to set up and use the grating one needs to obtain stellar spectrograms. It also discusses several methods on analyzing the results. This book is written in an easy to read style, perfect for getting started on the first night using the spectroscope, and specifically showing how the simple transmission filter is used on the camera or telescope. No heavy mathematics or formulas are involved, and there are many practical hints and tips - something that is almost essential to success when starting out. This book helps readers to achieve quick results, and by following the worked examples, they can successfully carry out basic analysis of the spectra.

The names of the seven Mercury astronauts were announced in April 1959 amid a flurry of publicity and patriotism. This work provides biographical details of all thirty-two finalists for the seven coveted places as America's pioneering astronauts. All of the candidates were among the nation's elite pilots involved in testing new supersonic aircraft capabilities. Most had served as wartime fighter and bomber pilots; some were test pilots on top secret and sophisticated aviation projects, while others were fleet admirals, prisoners of war, and proposed pilots for spaceflight programs such as the Dyna-Soar (X-20). The names of all 32 finalists have been kept secret until very recently. "Selecting the Mercury Seven" also relates the history and difficulties behind the initial choice of candidates. The lives, motivations, military careers, and achievements of the unsuccessful twenty-five finalists are explored first in fully authorized biographies. Test pilots for the U.S. Navy, Air Force, and Marine Corps, each man has a fascinating and very different story to tell. All thirty-two men had to endure meticulous, demeaning, and brutal week-long medical examinations at the Lovelace Clinic in New Mexico. This was followed by another torturous week at the Wright Aeromedical Laboratory in Ohio, where they were subjected to extreme fitness and physiological testing, the sole purpose of which was to sort out the Supermen from the near-supermen. The final part of the book examines the accomplishments and spaceflights of the seven successful candidates, bringing their amazing stories right up to date.

I have spent many wonderful nights observing at a variety of places around the world, but many of my fondest memories come from those made at the Custer Observatory in Southold on Long Island, where I grew up. I was only perhaps a dozen years old when I started out, and now more than three decades later I have logged millions of miles on the various telescopes there. Some of the best memories are of observing and discussing astronomical topics with the many really terrific people who make up Custer. It truly holds a special place in my heart. Star clusters were always among my favorite objects to observe and discuss there. This book is the result of the exposure to these objects, many of which I observed for the first time at Custer. The Custer Institute Observatory was founded in the 1920s by local resident Charles W. Elmer of Perkin-Elmer Corp. fame. The original crew met at his house in Cedar Beach a few miles down the road from the institute. In the 1930s the group built an observatory complete with Mr. Elmer's donated 5" Alvan Clark refractor. Later the observatory expanded to include a 6" Clark refractor and other even larger instruments.

Over the last 15 years or so there has been a huge increase in the popularity of astrophotography with the advent of digital SLR cameras and CCD imagers. These have enabled astronomers to take many images and, indeed, check images as they scan the skies. Processing techniques using computer software have also made 'developing' these images more accessible to those of us who are 'chemically challenged!' And let's face it - some of the pictures you see these days in magazines, books, and on popular web forums are, frankly, amazing! So, why bother looking through the eyepiece you ask? Well, for one thing, setting up the equipment is quicker. You just take your 'scope out of the garage or, if you're lucky enough to own one, open the roof of your observatory, align the 'scope and off you go. If you have an equatorial mount, you'll still need to roughly polar align, but this really takes only a few moments. The 'imager' would most likely need to spend more time setting up. This would include very accurate polar alignment (for equatorial mounts), then finding a guide star using his or her finder, checking the software is functioning properly, and c- tinuous monitoring to make sure the alignment is absolutely precise throu- out the imaging run. That said, an imager with a snug 'obsy' at the end of the garden will have a quicker time setting up, but then again so will the 'visual' observer.

This 2000 Edition of Sir Patrick Moore 's classic book has been completely revised in the light of changes in technology. Not only do these changes include commercially available astronomical telescopes and software, but also what we know and understand about the universe.

There are many new photographs and illustrations.

Packs a great deal of valuable information into appendices which make up almost half the book. These are hugely comprehensive and provide hints and tips, as well as data (year 2000 onwards) for pretty well every aspect of amateur astronomy.

This is probably the only book in which all this information is collected in one place.

Ever since its infancy, humankind has been seeking answers to some very basic and profound questions. Did the Universe begin? If it did, how old is it, and where did it come from? What is its shape? What is it made of? Fascinating myths and brilliant in- itions attempting to solve such enigmas can be found all through the history of human thought. Every culture has its own legends, itsownworldcreationtales, itsphilosophicalspeculations, itsre- gious beliefs. Modern science, however, cannot content itself with fanciful explanations, no matter how suggestive they are. No- days, our theories about the Universe, built upon rational ded- tion, have to survive the hard test of experiment and observation. Cosmology, the science which studies the origin and evo- tion of the Universe, had to overcome enormous dif?culties before it could achieve the same level of dignity as other physical dis- plines. At ?rst, it had no serious physical model and mathematical tools that could be used to address the complexity of the problems it had to face. Then, it suffered from a chronic lack of experim- tal data, which made it almost impossible to test the theoretical speculations. Given this situation, answering rigorously the many questions on the nature of the Universe seemed nothing more than a delusion. Today, however, things have changed. We live in the golden age of cosmology: an exciting moment, when, for the ?rst time, we are able to scienti?cally understand our Univers

During more than four decades of involvement in amateur astronomy, I have enjoyed the privilege of rubbing shoulders with numberless amateur and professional astr- omers. In so doing I have encountered at first, second, and third hand many of the joys and pitfalls that sky watchers can experience in pursuit of the universe's wonders. I have often howled at tall tales that would not disgrace a pirate's tavern. Many of these astounding stories have become the kernels of my Dear Steve column items. Learning how to operate the technology for observing and imaging the universe is work enough for any aspiring astronomer; however, many have problems of their own making. Not only do they share these troubles with other astronomers, they are on the receiving end of colleagues and friends doing the same. With all these agonized communications flying about, it is hard to understand how anyone gets any real work done! For the amusement of my peers I have long fondly parodied these imagined literary exchanges. These fantasy ''Agony Aunt'' questions began appearing in the pages of the Loughton Astronomical Society's monthly (and Christmas Special) journals about 30 years ago, in the guise of The astronomer's problem page. This was by the kind indulgence of the then editor, namely myself. Happily, even when the magazine of the LAS evolved into something much better, under the tender and loving care of those who came after me, these problem letters were still in demand and even now occasionally appear.

The Concise Knowledge Astronomy, published in 1898, was one of a series of popular reference books by experts. Agnes Clerke (1842 1907) was a successful author of books on astronomy and its history (three of her other works being reissued in this series), and her co-authors were astrophysicist Alfred Fowler, an internationally renowned expert in spectroscopy, and J. Elland Gore, a Fellow of the Royal Astronomical Society and expert on variable stars. Illustrated by over 100 photographs and drawings, the book aims to provide the educated non-specialist reader with an understanding of current astronomical knowledge. The application of new technologies, such as photography and spectroscopy, to astronomy in the nineteenth century had led to many new discoveries, and public interest in the subject had greatly increased. The book is divided into four parts - the history of astronomy, astronomical movements and instruments, the solar system, and sidereal astronomy.

First published in 1909, this autobiography details the astonishing life of Roger Langdon (1825 94), a country station-master and amateur astronomer. Langdon's life is a remarkable story of self-education and determination: he started work as a farmer's boy at the age of eight, ran away from the home to work for a shipowner in Jersey at fourteen, and was then employed by a blacksmith, canvas manufacturers, and a solicitor before finding work with the Great Western Railway. Langdon was from an early age interested in astronomy, and eventually constructed four telescopes and his own observatory. He developed his own method for photographing the moon and the transit of Venus, and presented a paper to the Royal Astronomical Society, which is included in the appendices. Langdon died before completing his autobiography, and the latter chapters on his scientific achievements and final years were completed by his daughter Ellen.

Written in 1877 by the French journalist Amedee Guillemin, this work appeared on British bookshelves at a time of intense interest in space, the solar system and stars. In the same year, Schiaparelli made his infamous 'discovery' of Martian canals, whetting the public's appetite for all things astronomical. Guillemin's account of comets was equally ambitious and, ultimately, more valuable. His subjects range from comet superstitions in Renaissance Italy to an accessible explanation of their orbits, constitution and brilliance. As James Glaisher notes in his Preface, 'there is no work that at all occupies the ground covered' by Guillemin. The author's imaginative prose, exemplified by his description of comets as 'long disowned stars', was translated sympathetically by Glaisher. Accompanied by eighty-five striking illustrations, including Halley's Comet as depicted in the Bayeux Tapestry, The World of Comets provides a fascinating insight into both astronomy and nineteenth-century scientific enquiry.

This work introduces the important emerging space powers of the world.

Brian Harvey describes the origins of the Japanese space program, from rocket designs based on WW II German U-boats to tiny solid fuel 'pencil' rockets, which led to the launch of the first Japanese satellite in 1970. The next two chapters relate how Japan expanded its space program, developing small satellites into astronomical observatories and sending missions to the Moon, Mars, comet Halley, and asteroids.

Chapter 4 describes how India's Vikram Sarabhai developed a sounding rocket program in the 1960s. The following chapter describes the expansion of the Indian space program. Chapter 6 relates how the Indian space program is looking ahead to the success of the moon probe Chandrayan, due to launch in 2008, and its first manned launching in 2014. Chapters 7, 8, and 9 demonstrate how, in Iran, communications and remote sensing drive space technology.

Chapter 10 outlines Brazil's road to space, begun in the mid-1960's with the launch of the Sonda sounding rockets. The following two chapters describe Brazil's satellites and space launch systems and plans for the future. Chapters 13 and 14 study Israel's space industry. The next chapters look at the burgeoning space programs of North and South Korea.

The book ends by contrasting and comparing all the space programs and speculating how they may evolve in the future. An appendix lists all launches and launch attempts to date of the emerging space powers.

Radio astronomy is far from being beyond the scope of amateurs astronomers, and this practical, self-contained guide for the newcomer to practical radio astronomey is an ideal introduction. This guide is a must for anyone who wants to join the growing ranks of 21st Century backyard radio astronomers. The first part of the book provides background material and explains (in a non-mathematical way) our present knowledge of the stronger radio sources - those observable by amateurs - including the Sun, Jupiter, Meteors, Galactic and extra-galactic sources. The second part of the book deals not only with observing, but - assuming no prior technical knowledge of electronics or radio theory - takes the reader step-by-step through the process of building and using a backyard radio telescope. There are complete, detailed plans and construction information for a number of amateur radio telescopes, the simplest of which can be put together and working - using only simple tools - in a weekend. For other instruments, there are full details of circuit-board layouts, components to use and (vitally important in radio astronomy) how to construct antennae for radio astronomy.

In this simple guide, David Levy inspires readers to experience the wonder of eclipses and other transient astronomical events for themselves. Covering both solar and lunar eclipses, he gives step-by-step instructions on how to observe and photograph eclipses. As well as explaining the science behind eclipses, the book also gives their historical background, discussing how they were observed in the past and what we have learned from them. This personal account contains examples from the 77 eclipses the author has witnessed himself. The guide also includes chapters on occultations of stars and planets by the Moon and of asteroids by stars, and the transits of Mercury and Venus. Tables of future eclipses make this invaluable for anyone, from beginners to practised observers, wanting to learn more about these fascinating events.

William F. Denning (1848 1931) was a British astronomer famous for his planetary observations and meteor studies. Elected president of the Liverpool Astronomical Society in 1887, he wrote a series of articles on telescopes for the society's journal, which were brought together and republished in 1891 under the title Telescopic Work for Starlight Evenings. Intended as a contribution to popular astronomy, this book provides a varied introduction to telescopes and their usage. The opening essay traces the development of the telescope from antiquity, through Galileo and Newton's contributions in the seventeenth century, to contemporary progress in astronomy. Other chapters provide practical advice for conducting planetary observation and detailed studies of particular planets, as well as facts and figures about meteors and how to compute their orbit. This book provides a fascinating insight into the evolution of astronomy and will be a valuable resource for historians of science and amateur astronomers.

Agnes Mary Clerke (1842 1907) first published A Popular History of Astronomy in 1885. The work was received with widespread acclaim and brought Clerke an international reputation as a science writer. The History surveys the progress made in the field of astronomy during the nineteenth century. It is split chronologically into two parts, dealing with the first and the second half of the century. Part 1 focuses on the career of the astronomer William Herschel (1738 1822) and the development of sidereal astronomy; part 2 deals with the discovery of spectrum analysis and the progress of knowledge about sun spots and the magnetic disturbances which cause them. Clerke's work, a classic example of Victorian popular scientific literature, stands alongside Grant's earlier History of Astronomy in its success in popularising the subject. The work is important today for scholars researching the history of the discipline and its place in educated Victorian society.

This autobiography was first published in 1883, and recounts the life of the Scottish scientist and inventor James Nasmyth (1808-1890), who was arguably the last of the early pioneers of the machine tool industry, most famously remembered for his invention of the steam hammer. He also produced and manufactured several other important machine tools, including a hydraulic press which used water pressure to force tight-fitting machine parts together. All of these machines became popular in manufacturing, and all are still in use today in modified forms. Nasmyth retired from business in 1856 at the age of just 48, and pursued his various hobbies including astronomy; he was co-author of The Moon: Considered as a Planet, a World, and a Satellite (1874) with James Carpenter. This autobiography follows a chronological order, and a list of Nasmyth's inventions is given at the end of the book.

Sir Robert Stawell Ball's Star-Land of 1889 is based on some of his Christmas Lectures at the Royal Institution during his time as royal astronomer of Ireland, a post he held from 1874 to 1892. These lectures were aimed at a young audience in order to introduce them to the subject, and fire their interest in the wonders of the universe. This volume includes lectures on the sun, the moon, the inner and giant planets, comets and shooting stars, and stars. It also contains a chapter on the observation and naming of stars. Ball was a renowned public lecturer, with commissions across Britain, Ireland and the United States, where his anecdotal and conversational style won him much popularity. The author of several frequently reprinted science books, he was knighted in 1886 and in 1892 became Lowendean professor of astronomy at Cambridge and the director of the university observatory.

John Browning (1830-1925) was the leading British manufacturer of precision scientific instruments, including spectroscopes, telescopes, microscopes, and opthalmoscopes. In How to Work with the Spectroscope (1878), he provides a complete overview of the field in which he was the undisputed expert, describing in detail the care and use of instruments ranging from the universal spectroscope to the star spectroscope to the induction coil. This volume also includes Browning's A Plea for Reflectors (1867), in which he provides an introduction to the silvered-glass reflecting telescope. Numerous illustrations of the various instruments and a complete price list of Browning's lenses and other apparatuses provide important insight into his business practices and range of expertise. Designed for the lay enthusiast no less than the dedicated scientist, these volumes are also valuable witnesses to the growth of popular science in nineteenth- and early twentieth-century Britain.

1543 saw the publication of one of the most significant scientific works ever written: De revolutionibus (On the Revolutions of the Heavenly Spheres), in which Nicolaus Copernicus presented a radically different structure of the cosmos by placing the sun, and not the earth, at the centre of the universe. But did anyone take notice? Harvard astrophysicist Owen Gingerich was intrigued by the bold claim made by Arthur Koestler in his bestselling The Sleepwalkers that sixteenth-century Europe paid little attention to the groundbreaking, but dense, masterpiece. Gingerich embarked on a thirty-year odyssey to examine every extant copy to prove Koestler wrong... Logging thousands of hours and hundreds of thousands of miles Gingerich uncovered a treasure trove of material on the life of a book and the evolution of an idea. His quest led him to copies once owned by saints, heretics, and scallywags, by musicians and movie stars; some easily accessible, others almost lost to time, politics and the black market. Part biography of a book and a man, part bibliographic and bibliophilic quest, Gingerich's The Book Nobody Read is an utterly captivating piece of writing, a testament to the power both of books and the love of books.
