"This book is one of the few modern texts on the interstellar medium. It is particularly excellent for microphysical processes and particularly those that are not easily accessible---physically oriented discussions of atomic and molecular excitation and radiation, molecular binding and astrochemical processes, and important detailed aspects of interstellar grains such as the observational manifestations and formation/destruction mechanisms."
- Carl Heiles, UC Berkeley, USA
This text covers the fundamental physics and chemistry required for a modern understanding of the interstellar medium. Radiation mechanisms are comprehensively presented, and extensive examples are drawn from observations in the X-ray, ultraviolet, optical, infrared, mm/sub mm, and radio observations. This book goes beyond a phenomenological study of the interstellar medium to give a detailed quantitative treatment of the radiative and dynamical interactions between stars and the interstellar medium. With an emphasis on a physical understanding of these processes, the mathematical derivations are clean, elegant and easily understandable by anyone with a background in physics.

'More analysis needed' is a comment lecturers repeatedly have to write on their students' work. Proceeding beyond this level of feedback is difficult when many students don't understand what analysis is or how to integrate criticism into their work. With this in mind, Critical Thinking Skills has taken the seemingly baffling art of analysis and broken it down into easy to understand blocks, with clear explanations, good examples, and plenty of activities to develop understanding at each stage. It even applies the techniques to reading, note making and writing. Recommending Critical Thinking Skills will help your students develop this important set of skills and improve their grades.
