Classical Electromagnetism via Relativity
One of the arts of teaching is to attack a problem from a different point of view, if the conventional approach has not been fully appreciated. This often helps the class to appreciate the conventional approach more fully. Maxwell's equations are generally introduced during a long course on electromagnetism, in which the correct interpretations and experimental bases of Maxwell's equations are sometimes obscured by the large amount of time of necessity devoted to the important applications of individual laws. The displacement 'current' is often introduced in a way that gives the wrong impression of its role in contemporary electromagnetic theory. There have been refinements of interpretation since Maxwell's time, particularly following the abandonment of the ether theories and the introduction of the theory of relativity. This is particularly true of the displacement 'current'. In this monograph, Maxwell's equations are approached from a different point of view from the conventional approach, namely using Coulomb's law and the transformations of the theory of special relativity. This approach illustrates the essential unity of Maxwell's equations, and the modern interpretation of the various terms in Maxwell's equations. It is the reverse of the historical approach, since the theory of special relativity arose out of optics and electromagnetism.

Relativity, Gravitation and Cosmology: A Basic Introduction

Relativity, Gravitation and Cosmology: A Basic Introduction By Ta-Pei Cheng
2009 | 355 Pages | ISBN: 0199573638 , 0199573646 | PDF | 6 MB

Relativity, Gravitation and Cosmology: A Basic Introduction
Einstein's general theory of relativity is introduced in this advanced undergraduate and beginning graduate level textbook. Topics include special relativity, in the formalism of Minkowski's four-dimensional space-time, the principle of equivalence, Riemannian geometry and tensor analysis, Einstein field equation, as well as many modern cosmological subjects, from primordial inflation and cosmic microwave anisotropy to the dark energy that propels an accelerating universe.
The author presents the subject with an emphasis on physical examples and simple applications without the full tensor apparatus. The reader first learns how to describe curved spacetime. At this mathematically more accessible level, the reader can already study the many interesting phenomena such as gravitational lensing, precession of Mercury's perihelion, black holes, and cosmology. The full tensor formulation is presented later, when the Einstein equation is solved for a few symmetric cases. Many modern topics in cosmology are discussed in this book: from inflation, cosmic microwave anisotropy to the "dark energy" that propels an accelerating universe.
Mathematical accessibility, together with the various pedagogical devices (e.g., worked-out solutions of chapter-end problems), make it practical for interested readers to use the book to study general relativity and cosmology on their own.

Particles and the Universe
English | Physics | May 2007 | ISBN-10: 0816061165 | 158 pages | pdf | 2.2 mb
Nuclear physics investigates the properties and behavior of the central portion, or nucleus, of the atom. This branch of physics had perhaps the biggest impact on the world in the 20th century because it evolved into the knowledge used to build the most destructive weapons people have ever known.

Particles and the Universe
The atomic bombs that ended World War II, and the weapons race that followed, changed the course of history. But applications of nuclear physics have also provided enormous energy for useful purposes, generating about 16 percent of the world's electricity. "" documents how modern physics formed and how it continues to evolve. Each chapter of this book delves into the observations, theories, and tests of a particular topic, including nuclear physics, quantum mechanics, particle physics, relativity, and cosmology.

English | ISBN: 9810220049, 9810220308 | 1994 | 500 pages | PDF | 18 MB

Knots and Applications
This volume is a collection of research papers devoted to the study of relationships between knot theory and the foundations of mathematics, physics, chemistry, biology and psychology. Included are reprints of the work of Lord Kelvin (Sir William Thomson) on the 19th-century theory of vortex atoms, reprints of modern papers on knotted flux in physics and in fluid dynamics, and knotted wormholes in general relativity. It also includes papers on Witten's approach to knots via quantum field theory and applications of this approach to quantum gravity and the Ising model in three dimensions. Other papers discuss the topology of RNA folding in relation to invariants of graphs and Vassiliev invariants, the entanglement structures of polymers, the synthesis of molecular Mobius strips and knotted molecules. The book begins with an article on the applications of knot theory to the foundations of mathematics and ends with an article on topology and visual perception. This volume should be of interest to workers interested in new possibilities in the uses of knots and knot theory.

Gravity: How the Weakest Force in the Universe Shaped Our Lives

Brian Clegg, "Gravity: How the Weakest Force in the Universe Shaped Our Lives"
English | ISBN: 0312616295 | 2012 | EPUB/MOBI | 336 pages | 1 MB

Gravity: How the Weakest Force in the Universe Shaped Our Lives
A history of gravity, and a study of its importance and relevance to our lives, as well as its influence on other areas of science. Physicists will tell you that four forces control the universe. Of these, gravity may the most obvious, but it is also the most mysterious. Newton managed to predict the force of gravity but couldn't explain how it worked at a distance. Einstein picked up on the simple premise that gravity and acceleration are interchangeable to devise his mind-bending general relativity, showing how matter warps space and time. Not only did this explain how gravity worked – and how apparently simple gravitation has four separate components – but it predicted everything from black holes to gravity's effect on time. Whether it's the reality of anti-gravity or the unexpected discovery that a ball and a laser beam drop at the same rate, gravity is the force that fascinates.

Physics Before And After Einstein
English | Physics | 30. May 2005 | ISBN-10: 3540428992 | 324 pages | pdf | 2 mb
It is now a century ago that one of the icons of modern physics published some of the most influential scientific papers of all times.

Physics Before And After Einstein
With his work on relativity and quantum theory, Albert Einstein has altered the field of physics forever. It should not come as a surprise that looking back at Einstein's work, one needs to rethink the whole scope of physics, before and after his time. This books aims to provide a perspective on the history of modern physics, spanning from the late 19th century up to today. It is not an encyclopaedic work, but it presents the groundbreaking and sometimes provocative main contributions by Einstein as marking the line between 'old' and 'new' physics, and expands on some of the developments and open issues to which they gave rise. This presentation is not meant as a mere celebration of Einstein's work, but as a critical appraisal which provides accurate historical and conceptual information. The contributing authors all have a reputation for working on themes related to Einstein's work and its consequences. Therefore, the collection of papers gives a good representation of what happened in the 100 years after Einstein's landmark Annalen der Physik articles. All people interested in the field of physics, history of science and epistemology could benefit from this book. An effort has been made to make the book attractive not only to scientists, but also to people with a more basic knowledge of mathematics and physics.
