This undergraduate text spreads itself too thin — despite being 454 pages long, it covers so many topics that you don't really get an in-depth treatment of anything.

The book gets off to a good start looking at several traditional PDE problems, such as the vibrating string, the drumhead, and heat flow, and derives the PDE for each one. Then it gradually builds more and more complete solutions to each problem, gradually bringing in boundary conditions, initial conditions, and eigenvalues. This takes the first quarter of the book.

Then it veers off in a pure-math direction for the second quarter of the book, giving fairly complete accounts of the theory of Fourier series (including convergence theorems, completeness, and the Gibbs phenomenon), harmonic functions, and Green's functions. There are no applications, though, so students who were excited by the good discussion of applications in the first quarter may lose interest.

Now the book starts being spread too thin. The last half of the book deals again with physical problems: very good ones such as the vibrating drum head (Bessel functions), Schrödinger's wave equation, the hydrogen atom, spherical harmonics, solitons, Maxwell's equations, shock waves, water waves, and more! But it only gives 3 or 4 pages to each subject. There's also some more pure-math stuff, such as a long chapter on eigenfunctions that is not tied very well to applications.

The book is unsatisfying because it is trying to do too many things. It's very clearly written but there's not enough depth. A book I like that is very old but covers many of the same physical problems in much more detail, and develops the needed mathematical background, and is one-tenth the price, is Donald H. Menzel's *Mathematical Physics* (Dover reprint, original publication 1947). Another book that I like, and which will give you a much better skill at solving PDEs in about 140 pages (although it skimps on the applications), is Erwin Kreyszig's Advanced Engineering Mathematics.
