Title: Good reference for solutions to diffusion equation
Review: If you are looking for mathematical solutions to diffusion equation under diffrent boundary conditions this is a good reference to have. For people interestted in numerical solutions and techniques this book may not serve the purpose other than getting analytical or approximate solutions to compare with their numerical implementation. There is a chapter on numerical methods, but the coverage is limited and it is introductory. Also, the book is not really about "mathematics" of diffusion - it is about "solutions to diffusion equation". To gain insights into solutions this is a very good book to read. In particular, there are discussions in this book on modeling diffusion in polymers that handle relevant aspects of the problem outside of just the math involved.
