Planetary Surface Processes is the first advanced textbook to cover the full range of geologic processes that shape the surfaces of planetary-scale bodies. Using a modern, quantitative approach, this book reconsiders geologic processes outside the traditional terrestrial context. It highlights processes that are contingent upon Earth's unique circumstances and processes that are universal. For example, it shows explicitly that equations predicting the velocity of a river are dependent on gravity: traditional geomorphology textbooks fail to take this into account. This textbook is a one-stop source of information on planetary surface processes, providing readers with the necessary background to interpret new data from NASA, ESA and other space missions. Based on a course taught by the author at the University of Arizona for 25 years, it is aimed at advanced students, and is also an invaluable resource for researchers, professional planetary scientists and space-mission engineers.

Thoroughly revised second edition of a highly successful book describing all aspects of meteorites.

In Planetary Systems from the Ancient Greeks, Theodor S. Kepler seeks to present a bird’s-eye view of the astronomical nature of the work of Newton’s predecessors. Rather than dwelling only on the influence of each thinker’s great ideas, Jacobsen tracks the actual details of their development by investigating the various systems involved and how they were used. As such, this book is an attempt to describe the specific processes through which (pre-Newtonian) astronomers derived a knowledge of the cosmos by observing the heavens and trying out detailed models to account for their observations. Planetary Systems from the Ancient Greeks contributes to scholarship on historical astronomy by offering an approach between that of popular, exact astronomical information and formal, fully referenced scholarly investigation. Each chapter is organized around a key astronomer (Eudoxus, Hipparchus, Ptolemy, Copernicus, Tycho Brahe, and Kepler) and offers relevant biographical introduction, exposition of the astronomical system, and assessment of their contributions. As Jacobsen suggests, the present elementary study of these historical astronomical systems also yields valuable insights for visualizing the salient facts of general astronomy.

Their charter is vague, their existence a secret buried under riddles and conspiracies, their sponsor an utter mystery, and their mission as diverse as the universe itself. Who better then to investigate amongst other things theoretical, snowflakes, and lost islands where monsters thrive?
