Laboratory Astronomy, written by Robert Wheeler Willson and published in 1905, is a comprehensive guide to the practical aspects of astronomical observation and experimentation. The book is divided into two parts: the first part covers the basics of astronomical instrumentation, including telescopes, spectroscopes, and other tools used in the study of the heavens. The second part of the book focuses on specific topics in astronomy, such as the measurement of stellar distances, the study of comets and meteorites, and the analysis of solar and lunar eclipses. Throughout the book, Willson emphasizes the importance of hands-on experimentation and observation, and provides detailed instructions and diagrams for conducting various experiments and observations. The book is intended for both amateur and professional astronomers, as well as students of astronomy and physics. With its practical approach and detailed explanations, Laboratory Astronomy remains a valuable resource for anyone interested in the science of astronomy.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
