From the reviews:

„A comprehensive work covering the material that graduate students in physics typically would study in preparing for doctoral candidacy examinations. … This book would be very useful for self-study by motivated students, or for preparation for candidacy exams. … Practicing physicists may find that the brief, accessible treatments of many topics will earn this book a place on a convenient bookshelf. Summing Up: Recommended. Upper-division undergraduates through professionals.“ (M. C. Ogilvie, CHOICE, Vol. 45 (7), 2008)

„The book, written by two … ‘working physicists’, contains what the authors regard as being ‘basic knowledge’ in the standard courses of theoretical physics (yet) held at German Universities. … is primarily intended to cover the ‘Basic Theoretical Physics’ in a single and handy volume. … Hence, the book should be considered as being a kind of ‘compendium’ of … formulas used in theoretical physics where the formulas are filledin between with some remarks.“ (Jürgen Tolksdorf, Zentralblatt MATH, Vol. 1134 (12), 2008)
