1919 hat das Preußische Ministerium für Wissenschaft, Kunst und Volksbildung die Akte "Einsteins Relativitätstheorie" angelegt. Sie wurde 1961 vom Autor wiederentdeckt und zusammen mit anderen inzwischen identifizierten Einstein-Akten aus deutschen Archiven zum Quellmaterial für dieses faszinierende Buch. Die Neuauflage kommentiert aufgrund akribischer Studien von 1600 Akten Einsteins FBI-Akte der Jahre 1950 - 1955 und legt bisher unbekanntes fabric zu Einsteins angeblichen Kontakten zur KPD und Komintern vor. Neu ist auch die gründliche Studie zu Einsteins Mitarbeit in der Völkerbund-Kommission, die sich auf Archivstudien in Genf stützt.

Das Buch zeichnet das Einsteinbild in der Politik und der Wissenschaftspolitik Deutschlands nach. Der Bogen spannt sich von seiner Berufung als Forscher nach Berlin über seine Rolle, nach dem 1. Weltkrieg den "Boykott der deutschen Wissenschaft" durch das Ausland überwinden zu helfen, bis zu seiner Rolle als Zielscheibe der Angriffe gegen die "jüdische Physik" im Inland. Es füllt damit eine wichtige Lücke in der Einsteinliteratur und trägt Neues zum besseren Verstehen für Einsteins rigorosen Bruch mit Deutschland bei.

Die Grundlagen der Elektrodynamik und Speziellen Relativitätstheorie werden in systematischer Weise eingeführt. Dabei stehen die physikalischen Prinzipien im Vordergrund und nicht so sehr die mathematischen Methoden, um Studierenden, deren zweites Fach nicht die Mathematik ist, einen leichteren Zugang zur Theorie zu bieten. Didaktische Anmerkungen und praxisnahe Übungsaufgaben helfen hierbei. Ausführlichere Rechnungen finden sich in den Anhängen des Buches. Es wird konsequent das Internationale Einheitensystem verwendet, um mit den Lehrbüchern der Experimental- und Schulphysik kompatibel zu sein.

Wichtige physikalische Begriffsbildungen werden ausführlich diskutiert und mit einer Vielzahl von Abbildungen illustriert: beispielsweise das Konzept des elektrischen Feldes und die Unterscheidung zwischen Fern- und Nahwirkung, die Rolle der Felder E und B sowie D und H oder die Bedeutung des Verschiebungsstroms. Querverbindungen zur Quantentheorie sind die Eichinvarianz und der Aharonov-Bohm-Effekt.

In der Relativitätstheorie werden folgende Themen behandelt: Inertialsysteme, Lorentz-Transformation, Zeitdilatation und Zwillingsparadoxon (mit Beispielen), Addition von Geschwindigkeiten, relativistische Masse und Energie, Doppler-Effekt, Vierervektoren, Anwendungen in der Beschleuniger- und Elementarteilchenphysik. Die enge Verknüpfung der elektromagnetischen Erscheinungen mit der Relativitätstheorie wird herausgearbeitet. Besonders wichtig ist die Erkenntnis, dass die Lorentz-Kraft als relativistische Ergänzung der Coulomb-Kraft gedeutet werden kann.

Im letzten Kapitel wird ein Ausblick auf die Dirac-Gleichung gegeben als relativistische Verallgemeinerung der Schrödinger-Gleichung. Die fundamentalen neuen Vorhersagen werden diskutiert: Existenz der Antiteilchen, Spin half und anomales magnetisches second des Elektrons.

Special relativity is the root of many fields in smooth physics: particle physics, quantum box thought, high-energy astrophysics, and so forth. This thought is gifted right here via adopting a 4-dimensional standpoint from the beginning. a good characteristic of the ebook is that it doesn’t limit itself to inertial frames yet considers speeded up and rotating observers. it's hence attainable to regard actual results similar to the Thomas precession or the Sagnac impression in an easy but unique demeanour. within the ultimate chapters, extra complicated issues like tensorial fields in spacetime, external calculus and relativistic hydrodynamics are addressed. within the final, short bankruptcy the writer provides a preview of gravity and exhibits the place it turns into incompatible with Minkowsky spacetime.

Well illustrated and enriched by way of many old notes, this ebook additionally offers many purposes of detailed relativity, starting from particle physics (accelerators, particle collisions, quark-gluon plasma) to astrophysics (relativistic jets, energetic galactic nuclei), and together with sensible functions (Sagnac gyrometers, synchrotron radiation, GPS). moreover, the publication offers a few mathematical advancements, reminiscent of the unique research of the Lorentz crew and its Lie algebra.

The publication is appropriate for college students within the 3rd yr of a physics measure or on a masters path, in addition to researchers and any reader drawn to relativity.
Thanks to the geometric strategy followed, this publication also needs to be necessary for the learn of common relativity.

“A glossy presentation of particular relativity needs to recommend its crucial constructions, earlier than illustrating them utilizing concrete purposes to express dynamical difficulties. Such is the problem (so effectively met!) of the gorgeous ebook by way of Éric Gourgoulhon.” (excerpt from the Foreword through Thibault Damour)

New PDF release: Discrete Causal Theory. Emergent Spacetime and the Causal

By Benjamin F. Dribus

ISBN-10: 331950083X

ISBN-13: 9783319500836

This e-book evaluates and indicates most likely severe advancements to causal set idea, one of many best-motivated techniques to the phenomenal difficulties of basic physics. Spacetime constitution is of primary significance to physics past common relativity and the traditional version. The causal metric speculation treats causal family because the foundation of this constitution. The e-book develops the results of this speculation lower than the belief of a primary scale, with delicate spacetime geometry considered as emergent. This procedure resembles causal set conception, yet differs in vital methods; for instance, the relative point of view, emphasizing kinfolk among pairs of occasions, and relationships among pairs of histories, is primary. The publication culminates in a dynamical legislation for quantum spacetime, derived through generalized course summation.
