In this comprehensive and interdisciplinary volume, former NASA Chief Historian Steven Dick reflects on the exploration of space, astrobiology and its implications, cosmic evolution, astronomical institutions, discovering and classifying the cosmos, and the philosophy of astronomy. The unifying theme of the book is the connection between cosmos and culture, or what Carl Sagan many years ago called the “cosmic connection.” As both an astronomer and historian of science, Dr. Dick has been both a witness to and a participant in many of the astronomical events of the last half century. This collection of papers presents his reflections over the last forty years in a way accessible to historians, philosophers, and scientists alike. From the search for alien life to ongoing space exploration efforts, readers will find this volume full of engaging topics relevant to science, society, and our collective future on planet Earth and beyond.

This book presents a novel mathematical formalism, based on the tetrad formulation of differential geometry, for describing cosmological observables exactly and conveniently. It covers all the standard observables, i.e. distances, weak lensing, number counts and cosmic microwave background, and also includes a detailed derivation of general-relativistic matrix kinetic theory. All the fully nonlinear equations are derived in detail and the mathematical content is self-contained, so that readers require only a basic knowledge of general relativity. Moreover, the authors discuss several subtle issues that are usually overlooked in the literature and, in particular, issues that distinguish this formalism from the more approximative standard practice.

Modern research has demonstrated that many stars are surrounded by planets—some of which might contain the right conditions to harbor life. This has only reinforced a question that has been tormenting scientists, philosophers and priests since Antiquity: Are there other inhabited worlds beyond our own? This book analyzes the many ways that humans have argued for and depicted extraterrestrial life over the centuries. The first known texts about the subject date from as early as the 6th century BC. Since that time, countless well-known historical characters like Lucretius, Aristotle, Thomas Aquinas, Cusanus, Bruno, Kepler, Descartes, and Huygens contributed to the debate; here, their lesser known opinions on the subject are studied in detail. It is often difficult for the modern mind to follow the thinking of our ancestors, which can only be understood when placed in the relevant context. The book thus extends its scope to the evolution of ideas about cosmology in general, as well as the culture in which these great thinkers wrote. The research is presented with the author's insight and humor, making this an easy and enjoyable read. .

This book presents an introduction to the metaphysical philosophy of nature put forward by Hedwig Conrad-Martius (1888-1966). Providing a unique perspective on central issues in modern and contemporary theoretical biology and physics, it will be of interest to anyone studying the history of the phenomenological movement as well as religious cosmology. The philosophical basis for this cosmology is Conrad-Martius’ “realontology”—a phenomenological account of the essence of reality. His position centers on the revival of ancient metaphysical themes in new transformed guises, especially potentiality and entelechy. Nature’s status, as a self-actuation of world-constituting essence-entelechies, places Conrad-Martius at the heart of philosophical-theological discussions of e.g. the hermeneutical mandate of demythologization as well as the nature of evolution. Of special interest is his insistence on both nature’s self-actuating and evolving powers and a robust theory of creation. .

The first comprehensive biography of Elihu Palmer tells the life story of a freethinker who was at the heart of the early United States' protracted contest over religious freedom and free speech.When the United States was new, a lapsed minister named Elihu Palmer shared with his fellow Americans the radical idea that virtue required no religious foundation. A better source for morality, he said, could be found in the natural world: the interconnected web of life that inspired compassion for all living things. Religions that deny these universal connections should be discarded, he insisted. For this, his Christian critics denounced him as a heretic whose ideas endangered the country.Although his publications and speaking tours made him one of the most infamous American freethinkers in his day, Elihu Palmer has been largely forgotten. No cache of his personal papers exists and his book has been long out of print. Yet his story merits telling, Kirsten Fischer argues, and not only for the dramatic account of a man who lost his eyesight before the age of thirty and still became a book author, newspaper editor, and itinerant public speaker. Even more intriguing is his encounter with a cosmology that envisioned the universe as interconnected, alive with sensation, and everywhere infused with a divine life force.Palmer's "heresy" tested the nation's recently proclaimed commitment to freedom of religion and of speech. In this he was not alone. Fischer reveals that Palmer engaged in person and in print with an array of freethinkers—some famous, others now obscure. The flourishing of diverse religious opinion struck some of his contemporaries as foundational to a healthy democracy while others believed that only a strong Christian faith could support democratic self-governance. This first comprehensive biography of Palmer draws on extensive archival research to tell the life story of a freethinker who was at the heart of the new nation's protracted contest over religious freedom and free speech—a debate that continues to resonate today.

The goal of this essay is to discuss the future of discovery in particle physics. Its primary motivation is the 2019 European Strategy update, which aims to determine the future experimental and theoretical priorities for particle physics. A key question is to understand what the standard theory (Standard Model) of particle physics really is, which the author argues has been a foggy notion for several decades which he clarifies. It then is to decide what motivated beyond the Standard Model theories are to be targeted by experiment. This book brightly exposes these theories, and puts current particle physics research into its historical context and points the way toward future work.

This second, revised and thoroughly updated edition of the successful textbook by Claus Grupen describes the branch of astrophysics known as astroparticle physics. Using experimental methods known from cosmic ray and particle physics, astroparticle physics investigates processes of highest energies taking place in the universe. The new edition reports on progress made by recent discoveries in gravitational wave astronomy and neutrino astronomy (including all details needed to understand recent discoveries in multi-messenger experiments) and also astrobiology. After a historical introduction to the basics of elementary particles the author describes their interactions and the relevant detection techniques. The main body of the book concerns cosmic rays as well as particle processes in astrophysics and cosmology including the physics of the early universe. The book provides an orientation in the field of astroparticle physics that many beginners might be looking for. It also presents new sections exploring the interface between particle physics and cosmic radiation and illustrates the impact of particle physics discoveries to astroparticle physics. The physics is presented using little mathematics, and the results are illustrated by many diagrams and illustrative scientific cartoons which ease the reading of the book. Closing the gap between expert and popular level, the book is highly recommended for undergraduate students in physics or astronomy. It also includes an extensive glossary and a detailed index.
