RELATIVISTIC QUANTUM MECHANICS WAVE EQUATIONS

More than a generation of German-speaking students around the world have worked their way to an understanding and appreciation of the power and beauty of modern theoretical physics with mathematics, the most fundamental of sciences using Walter Greiner's textbooks as their guide. The idea of developing a coherent, complete presentation of an entire field of science in a series of closely related textbooks is not a new one. Many older physicists remember with real pleasure their sense of adventure and discovery as they worked their ways through the classic series by Sommerfeld, by Planck and by Landau and Lifshitz. From the students' viewpoint, there are a great many obvious advantages to be gained through use of consistent notation, logical ordering of topics and coherence of presentation; beyond this, the complete coverage of the science provides a unique opportunity for the author to convey his personal enthusiasm and love for his subject.

ASTROPHYSICS AND SPACE SCIENCE LIBRARY

This book deals with topics in atomic and molecular structure and dynamics that are important to astronomy. Indeed, the topics selected are of central interest to the field of astronomy, many having been initiated by the needs of understanding worlds other than ours. Except for some lunar surface material returned by the Apollo missions, and material naturally delivered to us by cosmic rays, comets, and meteors, our only access to the other worlds of our astronomical Universe is through our observations of electromagnetic radiation from them. (Very recently, neutrinos from the Sun and supernovae have also been studied, and there are hopes for observations of gravitational waves in the next decades.)

QUARKS AND LEPTONS: An Introductory Course in Modern Particle Physics

Dramatic progress has been made in particle physics during the past two decades. A series of important experimental discoveries has firmly established the existence of a subnuclear world of quarks and leptons. The protons and neutrons ("nucleons"), which form nuclei, are no longer regarded as elementary particles but are found to be made of quarks. That is, in the sequence molecules atoms → nuclei nucleons, there is now known to be another "layer in the structure of matter." However, the present euphoria in particle physics transcends this remarkable discovery. The excitement is due to the realization that the dynamics of quarks and leptons can be described by an extension of the sort of quantum field theory that proved successful in describing the electromagnetic interactions of charged particles. To be more precise, the fundamental interactions are widely believed to be described by quantum field theories possessing local gauge symme- try. One of the aims of this book is to transmit a glimpse of the amazing beauty and power of these gauge theories. We discuss quarks and leptons, and explain how they interact through the exchange of gauge field quanta (photons, gluons, and weak bosons).

Мой продуктивный год: Как я проверил самые известные методики личной эффективности на себе

Я рассказываю о своих достижениях не для того, чтобы произвести на вас впечатление, а чтобы показать, насколько мощным инструментом могут стать приемы, повышающие продуктивность. И как бы мне ни было лестно так думать, но два места работы по окончании университета мне предложили вовсе не потому, что я был каким-то особенно умным или одаренным.

Quantum versus Chaos

The framework of quantum mechanics in the adiabatic limit where no quantum transition occurs is traced back to the quantization condition of adiabatic invariants, i.e., of action variables. In fact, the interpretation of this condition as the commutation rule for a pair of canonical variables led to the construction of Heisenberg's matrix equation; another interpretation of this condition, as that for confining a standing wave, led to the birth of Schrö dinger's wave mechanics. In classically-chaotic systems, however, the stable tori are broken up and we can conceive no action to be quantized. Therefore, we cannot prevent ourselves from being suspicious of using the present formalism of quantum mechanics beyond the logically acceptable (i.e., classicallyintegrable) regime. Actually, quantum dynamics of classically-chaotic systems yields only quasi-periodic and recurrent behaviors, thereby losing the classical-quantum correspondence. There prevails a general belief in the incompatibility between quantum and chaos. Presumably, a generalized variant of quantum mechanics should be established so as to accommodate the temporal chaos.

Die Region – eine Begriffserkundung

All diese Begriffe lassen sich in Wörterbüchern als Synonyme und Defi nitionsele-mente des Begriffs Region fi nden. Die Auflistung verdeutlicht, dass eine generelleBegriffsbestimmung ein fragwürdiges Unterfangen wäre. Oder wie Ute Wardengabei unserem Autor: innentreffen anmerkte, wäre es der Versuch, einen Pudding an die Wand zu nageln.
