Spectroscopic Instrumentation – Fundamentals and Guidelines for Astronomers
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.
The Moon Hoax? – Conspiracy Theories on Trial
- A carefully researched and gripping story examining the persistent claims of conspiracy theorists
- Written by an astrophysicist and expert on space missions
- Shows clearly how to distinguish facts from “alternative facts”
- Appeals to all readers with an interest in space exploration
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.
