There is no doubt that next generation of the textbooks with be on-line only.
This is why we are working on a project which brings together traditional texts,
say in pdf, computer graphics, animations and on-line research evaluations,
video and reference sources, all under one web-oriented platform for the benefits
of our students and next generation of researchers. We will concentrate on several
topics in theoretical and mathematical physics, classical and quantum optics and
nonlinear science, based on our original results. Our group includes professors and
ASU graduates.
