Sommario/riassunto |
|
Separation of scales plays a fundamental role in the understanding of the dynamical behaviour of complex systems in physics and other natural sciences. A prominent example is the Born-Oppenheimer approximation in molecular dynamics. This book focuses on a recent approach to adiabatic perturbation theory, which emphasizes the role of effective equations of motion and the separation of the adiabatic limit from the semiclassical limit. A detailed introduction gives an overview of the subject and makes the later chapters accessible also to readers less familiar with the material. Although the general |

mathematical theory based on pseudodifferential calculus is presented in detail, there is an emphasis on concrete and relevant examples from physics. Applications range from molecular dynamics to the dynamics of electrons in a crystal and from the quantum mechanics of partially confined systems to Dirac particles and nonrelativistic QED. |

Sommario/riassunto |
|
Christian readers of the Hebrew Bible are often faced with a troubling tension. On the one hand, they are convinced that this ancient text is relevant today, yet on the other, they remain perplexed at how this can be so, particularly when parts of it appear to condone violence. Barker's volume seeks to address this tension in two parts: (1) by defending a particular form of theological interpretation and (2) by applying this interpretive method to the imprecatory psalms.Barker suggests that the goal of theological interpretation is to discover God's voice in the text. While he recognizes that this goal could encourage a subjective methodology, Barker offers a hermeneutic that clearly locates God's voice in the text of Scripture. Utilizing the resources of speech act theory, Barker notes that texts convey meaning at a number of literary levels and that God's appropriation of speech acts at these levels is not |

necessarily uniform for each genre. He also discusses how the Christian canon alters the context of these ancient speech acts, both reshaping and enabling their continued function as divine discourse. In order to demonstrate the usefulness of this hermeneutic, Barker offers theological interpretations of Psalms 69 and 137. He demonstrates how christological fulfilment and the call to forgive one's enemies are determinative for a theological interpretation of these troubling psalms, concluding that they continue to form an essential part of God's voice that must not be ignored. |
