'The text is easy to read because the matter is clearly explained. Symmetries are a central component of physical laws, and the PT-symmetry proves to be very interesting and fruitful. The discussion of the matter is up-to-date and self-contained. The book is recommended to students of higher courses, PhD and researchers. It is also a basic read to those who wish to have an insight into this field.'Contemporary PhysicsOriginated by the author in 1998, the field of PT (parity-time) symmetry has become an extremely active and exciting area of research. PT-symmetric quantum and classical systems have theoretical, experimental, and commercial applications, and have been the subject of many journal articles, PhD theses, conferences, and symposia. Carl Bender's work has influenced major advances in physics and generations of students.This book is an accessible entry point to PT symmetry, ideal for students and scientists looking to begin their own research projects in this field.

Der Band gibt wichtige Impulse fur die methodologische Reflexion der historischen Kulturwissenschaften. Er geht auf eine Tagung zuruck (Mainz, November 2006), deren Thema "Dichtung und Wahrheit. Zum Verhaltnis von Narration und Erklarung in den Kultur-, Geistes- und Sozialwissenschaften" war. Die Autoren greifen zum ersten Mal im kulturwissenschaftlichen Kontext Anregungen vor allem aus der Analytischen Philosophie auf und diskutieren ihren Wert fur historisches und kulturwissenschaftliches Arbeiten. Im Fokus der Untersuchungen steht eine Begriffstrias, die fur die Sozial-, Geistes- und Kulturwissenschaften gleichermassen seit dem 19. Jahrhundert eine grosse Herausforderung darstellt: Erklaren, Verstehen und Erzahlen."
