One of the peculiarities of Astrophysics is that, as a
subject, is difficult to teach. It requires to go deep into
the physics of the objects under study (which span the whole
Universe) but alto to keep a broad view (the so called "Big
Picture") since most of the objects and their histories
cannot be understood if they are isolated from the others.
One of the problems a teacher faces is, hence, how to strike a
balance between these two disparate goals within the limited
time of one or two academic terms.

Rybicki and Lightman success with this book is to take the
physics of astrophysical problems involving radiation from
the general approaches of the physics books to the particular
conditions of most of the cases that astronomy cares about
without leaving rigorousity along the way. With a little
abuse of language: They bring Physics a step closer to
Astronomy.

On the other hand, the area of actual applications that
astronomers use is almost neglected. For example, the
introductory chapters on Radiative Transfer and Black
Body Radiation could have served to motivate a chapter on
theoretical basis of photometry (theoretical approach to
color indices, extinction by dust or other microscopic
particles). This would have given the student a more
realistic flavor of the tools that astrophysicists use
in their everyday (every night?) work. The Problem Sets,
in addition, are claiming for a few numerical
applications to profit from the, now easily available
to students, computer power.

Every serious astrophysics teacher and student should
use this book... and think hard on how to take the
next step from Rybicki and Lightman to the Absolute
Magnitude versus Color Index diagrams.

This is THE standard text in the field of astrophysical radiation processes. Covers most processes of interest for the astrophysicist, at a depth adequate for graduate students. Well written and understandable. A must buy, despite the very high price.

Thorough, concise, and very readable. Topics are clearly presented, equations are elegantly explained. One of the most useful texts I own.
