This textbook is the result of many years of teaching quantum and
statistical mechanics, drawing on exercises and exam papers used on
courses taught by the authors. The subjects of the exercises have been
carefully selected to cover all the material which is most needed by
students.
Each exercise is carefully solved in full details, explaining the theory
behind the solution with particular care for those issues that students
often find difficult, or which are often neglected in other books on the
subject. The exercises in this book never require extensive calculations
but tend to be somewhat unusual and force the solver to think about the
problem starting from first principles, rather than by analogy with some
previously solved exercise.
