This book describes our gradual awareness of a vast, previously concealed Universe. It is a story of expanding horizons and the discovery of invisible worlds. This voyage of discovery is presented within universal themes, such as invisibility, motion, content, form, impermanence, violence and emptiness, beginnings and ends. These are topics that concern us all, helping us take the Universe personally, so each chapter begins with the human aspect of some of these themes. The book is additionally broadened by including the perceptions of artists, poets and writers, as well as with line drawings that forcefully compact a scientific insight.

Cosmology is the study of the origin, size, and evolution of the entire universe. Every culture has developed a cosmology, whether it be based on religious, philosophical, or scientific principles. In this book, the evolution of the scientific understanding of the Universe in Western tradition is traced from the early Greek philosophers to the most modern 21st century view. After a brief introduction to the concept of the scientific method, the first part of the book describes the way in which detailed observations of the Universe, first with the naked eye and later with increasingly complex modern instruments, ultimately led to the development of the "Big Bang" theory. The second part of the book traces the evolution of the Big Bang including the very recent observation that the expansion of the Universe is itself accelerating with time.

Essential Astrophysics is a book to learn or teach from, as well as a fundamental reference volume for anyone interested in astronomy and astrophysics. It presents astrophysics from basic principles without requiring any previous study of astronomy or astrophysics. It serves as a comprehensive introductory text, which takes the student through the field of astrophysics in lecture-sized chapters of basic physical principles applied to the cosmos. This one-semester overview will be enjoyed by undergraduate students with an interest in the physical sciences, such as astronomy, chemistry, engineering or physics, as well as by any curious student interested in learning about our celestial science. The mathematics required for understanding the text is on the level of simple algebra, for that is all that is needed to describe the fundamental principles. The text is of sufficient breadth and depth to prepare the interested student for more advanced specialised courses in the future. Astronomical examples are provided throughout the text, to reinforce the basic concepts and physics, and to demonstrate the use of the relevant formulae. In this way, the student learns to apply the fundamental equations and principles to cosmic objects and situations. Astronomical and physical constants and units as well as the most fundamental equations can be found in the appendix. Essential Astrophysics goes beyond the typical textbook by including references to the seminal papers in the field, with further reference to recent applications, results, or specialised literature.

Beyond the cosmic veil, between rhyme and reason, sits Cthulhu - water god. He knows your pain and disrupts your reason. He is the canker of all mankind... and he is loose! Join the writers of Barbwire Butterfly Books for a new slant on the Cthulhu mythos - as the shared universe of H.P Lovecraft is reinterpreted and reimagined by a new breed of authors.

Radio astronomy was born during the Second World War, but as this book explains, the history of early Dutch radio astronomy is in several respects rather anomalous in comparison to the development of radio astronomy in other countries. The author describes how these very differences led the Netherlands to become one of the world leaders in radio astronomy. Dominated by the Leiden astronomer Jan Hendrik Oort, the field embarked on an era of success, and to this day, the country still holds a leading position. To tell this story, the book focuses on three key events in the period 1940-1970, namely the construction of the radio telescopes in Kootwijk (1948), in Dwingeloo (1956), and in Westerbork (1970). These projects show that Dutch radio astronomers must not be seen as merely scientists, but also as strategic lobbyists, networkers and organizers in a specific political and economic context. It was in the process of planning, designing and constructing these instruments that the interests of the astronomers, industrial partners, politicians and lobby groups merged to create today's existing research centers for radio astronomy.

Astronomy and Astrophysics is a comprehensive, fundamental, and up-to-date reference book. It is filled with vital information and basic facts for amateur astronomers and professional astrophysicists, and for anyone interested in the Universe, from the Earth and other planets to the stars, galaxies and beyond. An exceptionally thorough Index cross-references concepts, discoveries and individuals in both the Timeline section and Dictionary section. The combined result is a unique stand-alone reference volume in which the reader can quickly locate information, while also discovering new and unexpected knowledge.
