...perhaps the only modern advanced undergraduate or
graduate introduction to the subject…put together very elegantly and
intelligently, illustrated by many examples from geophysics, astrophysics and
other fields…a pleasure to teach. For a student who has already encountered
solid and fluid mechanics, the text offers rigor and breadth; nothing is
asserted, everything is derived.
