In order to analyze the light of cosmic objects, particularly at extremely great distances, spectroscopy is the workhorse of astronomy. In the era of very large telescopes, long-term investigations are mainly performed with small professional instruments. Today they can be done using self-designed spectrographs and highly efficient CCD cameras, without the need for large financial investments. This book explains the basic principles of spectroscopy, including the fundamental optical constraints and all mathematical aspects needed to understand the working principles in detail. It covers the complete theoretical and practical design of standard and Echelle spectrographs. Readers are guided through all necessary calculations, enabling them to engage in spectrograph design. The book also examines data acquisition with CCD cameras and fiber optics, as well as the constraints of specific data reduction and possible sources of error. In closing it briefly highlights some main aspects of the research on massive stars and spectropolarimetry as an extension of spectroscopy. The book offers a comprehensive introduction to spectroscopy for students of physics and astronomy, as well as a valuable resource for amateur astronomers interested in learning the principles of spectroscopy and spectrograph design.

This book is about the American moon-landings - and about the doubts expressed ever since concerning the reality of these landings. Were the images of men on the moon really just a huge and cleverly executed hoax? Eversberg explains the best-known claims and conspiracy theories, and analyses the evidence with the help of detailed full-colour images, as well as numerous film documents that can be accessed directly from the book. He addresses both the persistent older claims and more recently devised doubts. The book will inform and entertain a wide range of readers interested in space exploration and tells a gripping story covering physics, politics and history.

"Ein Jahrtausendereignis - ein technischer Triumph: Menschen waren auf dem Mond Oder - und kann das uberhaupt moglich sein? - sind wir einer Tauschung unterlegen?Einerpolitisch motivierten globalen Inszenierung, deren Bilder und Filme in einem Studio entstanden sind?"(Aus dem Video-Trailer zum Buch)

Hollywood im Weltall handelt von den Landungen der Amerikaner auf dem Mond - und von den seit vierzig Jahren bestehenden Zweifeln vieler Menschen, ob diese Landungen wirklich stattgefunden haben.Eversberg setzt sich mit den bekanntestenLugen, Verschworungstheorien und Bedrohungen auseinander undanalysiert diese in vierfarbigen Detailaufnahmenund mit vielen vom Buch aus abrufbaren Filmsequenzen. Dabei gehter sowohl aufdie altesten gut bekannten, aber auchdieaktuellsten Zweifel an der Mondlandung ein- und bietet Lesern aller Altersstufen so einen spannenden Krimi aus Physik, Politik und Geschichte.

"Aus dem Vorwort: "

"Vor einigen Jahren fragten mich einige Freunde, ob ich eigentlich an die Mondlandungen ""der Amerikaner in den 60er und 70er Jahren des letzten Jahrhunderts glauben wurde. Uber ""diese Frage war ich nicht wenig uberrascht, hatte ich die Mondlandungen doch als Kind gebannt verfolgt und in der Schule begeistert Raketen gemalt. Da meine Freunde aber intelligente Menschen sind, begann ich, mir die Problematik genauer anzusehen. Damals konnte ich noch nicht ahnen, dass ich mir damit einige Arbeit eingehandelt hatte; denn zwischen einer Behauptung und einer begrundeten Argumentation bestehteine ziemliche Diskrepanz. So habe ich mich denn im Laufe vieler Monate mit den bekanntesten bis hin zu den aktuellsten Thesenrund um die Mondlandung auseinander gesetzt - das Ergebnis ist dieses Buch."
