Congratulations to Professor Viraht Sahni of the Physics Department for his latest book, Schrödinger Theory of Electrons: Complementary Perspectives (Springer Tracts on Modern Physics 285), published by Springer. This is Professor Sahni’s fourth book, and like its predecessors, focuses on the field of quantum mechanics by providing new perspectives on quantum theory, and new physical and mathematical understandings of quantum systems. Professor Sahni expects that the book will be used to supplement the material presently taught in courses on quantum mechanics and quantum chemistry, as it is written in a pedagogical manner easily accessible to senior undergraduates, graduate students, and researchers in the broad area of electronic structure.
