This book provides a detailed interdisciplinary review of publications on the impact of solar activity --- space weather on social indicators, such as the rhythm of historical processes, military activity, social instability, and creative productivity. The work can be considered as a detailed commentary on A.L. Chizhevsky's brochure "Physical Factors of the Historical Process." The book will be useful to all naturalists and humanitarians, including psychologists, cultural scientists and philosophers who are interested in the mysteries of solar-terrestrial connections.
