The standard model of particle physics describes our current understanding of nature's fundamental particles and their interactions, yet gaps remain. For example, it does not include a quantum theory of gravity, nor does it explain the existence of dark matter. Once complete, however, the standard model could provide a unified description of the very building blocks of the universe. Researchers have been chasing this dream for decades, and many wonder whether such a dream can ever be made a reality. Can the Laws of Physics Be Unified? is a short introduction to this exciting frontier of physics. The book is accessibly written for students and researchers across the sciences, and for scientifically minded general readers. Paul Langacker begins with an overview of the key breakthroughs that have shaped the standard model, and then describes the fundamental particles, their interactions, and their role in cosmology. He goes on to explain field theory, internal symmetries, Yang-Mills theories, strong and electroweak interactions, the Higgs boson discovery, and neutrino physics. Langacker then looks at the questions that are still unanswered: What is the nature of the mysterious dark matter and dark energy that make up roughly 95 percent of the universe? Why is there more matter than antimatter? How can we reconcile quantum mechanics and general relativity? Can the Laws of Physics Be Unified? describes the promising theoretical ideas and new experiments that could provide answers and weighs our prospects for establishing a truly unified theory of the smallest constituents of nature and their interactions.

Though astrophysicists have developed a theoretical framework for understanding how the first stars and galaxies formed, only now are we able to begin testing those theories with actual observations of the very distant, early universe. We are entering a new and exciting era of discovery that will advance the frontiers of knowledge, and this book couldn't be more timely. It covers all the basic concepts in cosmology, drawing on insights from an astronomer who has pioneered much of this research over the past two decades. Abraham Loeb starts from first principles, tracing the theoretical foundations of cosmology and carefully explaining the physics behind them. Topics include the gravitational growth of perturbations in an expanding universe, the abundance and properties of dark matter halos and galaxies, reionization, the observational methods used to detect the earliest galaxies and probe the diffuse gas between them--and much more. Cosmology seeks to solve the fundamental mystery of our cosmic origins. This book offers a succinct and accessible primer at a time when breathtaking technological advances promise a wealth of new observational data on the first stars and galaxies. Provides a concise introduction to cosmology Covers all the basic concepts Gives an overview of the gravitational growth of perturbations in an expanding universe Explains the process of reionization Describes the observational methods used to detect the earliest galaxies

The revolution in twentieth century physics has changed the way we think about space, time and matter and our own place in the universe. It has offered answers to many of the big questions of existence, such as the ultimate nature of things and the how the universe came into being. It has undermined our belief in a Newtonian mechanistic universe and a deterministic future, posing questions about parallel universes, time-travel and the origin and end of everything. At the same time we have witnessed amazing attempts at unification so that physicists are able to contemplate the discovery of a single 'theory of everything' from which we could derive the masses and types of all particles and their interactions. This book tells the story of these discoveries and the people who made them, largely through the work of Nobel Prize winning physicists.

Die Quantenelektrodynamik (QED) beschreibt die Wechselwirkung von Licht und Materie, genauer: die Wechselwirkung von Elektronen, Positronen und Photonen. Mittlerweile ist diese Theorie schon älter als ein halbes Jahrhundert. Im Laufe der Jahre ist sie in vielen Energiebereichen getestet worden, nicht zuletzt mit Hilfe der modernen Teilchenbeschleuniger. Um so überraschender ist die Tatsache, daß man bis heute keinerlei Abweichungen zwischen den theoretischen Voraussagen und den experimentellen Daten gefunden hat! Die QED zählt damit zu den genauesten aller Theorien. Dieses Werk führt in die wichtigsten Ergebnisse und Rechenverfahren der Quantenelektrodynamik ein. Aus erster Hand wird der Leser auch mit den berühmten "Feynman-Graphen" vertraut gemacht.

This volume includes a representative selection of Sidney Drell''s recent writings and speeches (circa 1993 to the present) on public policy issues with substantial scientific components. Most of the writings deal with national security, nuclear weapons, and arms control and reflect the authorOCOs personal involvement in such issues dating back to 1960. Fifteen years after the demise of the Soviet Union, the gravest danger presented by nuclear weapons is the spread of advanced technology that may result in the proliferation of nuclear weapons. Of most concern would be their acquisition by hostile governments and terrorists who are unconstrained by accepted norms of civilized behavior. The current challenges are to prevent this from happening and, at the same time, to pursue aggressively the opportunity to escape from an outdated nuclear deterrence trap."

Der Weg zur Wirklichkeit ist eine Kurzübersetzung des Penrose-Klassikers "The Road to Reality", die aus dem Monumentalwerk für Physik- und Mathematikexperten die allgemeinverständlichen Kapitel für interessierte Laien lesbar macht. Wer ein Faible für die Grundfragen der Wissenschaft, einen Blick für Geometrie, einen Sinn für Zahlen und Neugier für kosmologische Theorien hat, findet in diesem klar und kompetent geschriebenen Buch überraschende und provozierende Ideen. Schulmathematik wie die Bruchrechnung oder der berühmte Pythagorassatz lassen sich auf dem Weg zur Wirklichkeit völlig neu entdecken - im Spannungsfeld zwischen platonischer Mathematik, physikalischer Welt und menschlichem Bewusstsein.
