This book discusses analogies between relativistic cosmology and various physical systems or phenomena, mostly in the earth sciences, that are described formally by the same equations. Of the two independent equations describing the universe as a whole, one (the Friedmann equation) has the form of an energy conservation equation for one-dimensional motion. The second equation is fairly easy to satisfy (although not automatic): as a result, cosmology lends itself to analogies with several systems. Given that a variety of universes are mathematically possible, several analogies exist. Analogies discussed in this book include equilibrium beach profiles, glacial valleys, the shapes of glaciers, heating/cooling models, freezing bodies of water, capillary fluids, Omori's law for earthquake aftershocks, lava flows, and a few mathematical analogies (Fibonacci's sequence, logistic equation, geodesics of various spaces, and classic variational problems). A century of research in cosmology can solve problems on the other side of an analogy, which in turn can suggest ideas in gravity. Finding a cosmic analogy solves the inverse variational problem of finding a Lagrangian and a Hamiltonian for that system, when nobody thought one exists. Often, the symmetries of the cosmological equations translate in new symmetries of the analogous system. The book surprises the reader with analogies between natural systems and exotic systems such as possible universes.

Recently, analogies between laboratory physics (e.g. quantum optics and condensed matter) and gravitational/cosmological phenomena such as black holes have attracted an increasing interest. This book contains a series of selected lectures devoted to this new and rapidly developing field. Various analogies connecting (apparently) different areas in physics are presented in order to bridge the gap between them and to provide an alternative point of view.

The first comprehensive study of the origins, motivations, and methods of Greek doctors who investigated the universe as a whole.

Renaissance images could be real as well as linguistic. Human beings were often believed to be an image of the cosmos, and the sun an image of God. Kathryn Banks explores the implications of this for poetic language and argues that linguistic images were a powerful tool for rethinking cosmic conceptions. She reassesses the role of natural-philosophical poetry in France, focusing upon its most well-known and widely-read exponent, Guillaume de Saluste Du Bartas.Through a sustained analysis of Maurice Sceve's Delie , Banks also rethinks love lyric's oft-noted use of the beloved as image of the poet. Cosmos and Image makes an original contribution to our understanding of Renaissance thinking about the cosmic, the human, and the divine. It also proposes a mode of reading other Renaissance texts, and reflects at length upon the relation of 'literature' to history, to the history of science, and to political turmoil.

This is the only book to deal with classical Islamic cosmology as it was formulated by the Ikhwan al-S'afa al Biruni and Ibn Sina during the tenth and eleventh centuries. These figures influenced all the later centuries of Islamic history and in fact created the cosmological framework within which all later scientific activity in the Islamic world was carried out--the enduring image of the cosmos within which Muslims have lived during the past millennium. Nasr writes from within the Islamic tradition and demonstrates how, based on the teachings of the Quran and the Prophet, the figures treated in this work integrated elements drawn from various ancient schools of philosophy and the sciences. This book is unique in its treatment of classical Islamic cosmology as seen from within the Islamic world-view and provides a key for understanding of traditional Islamic thought. -- Back cover.
