Ohanian and Ruffini's Gravitation and Spacetime, Second Edition, the authors is the best book on the market today of 500 pages or less on gravitation and general relativity.Abstract:
Now more than ever, Gravitation and Spacetime, Second Edition, by Hans C. Ohanian and new coauthor Remo Ruffini, deserves John Wheeler's praise as "the best book on the market today of 500 pages or less on gravitation and general relativity." Gravitation and Spacetime has been thoroughly updated with the most exciting finds and hottest theoretical topics in general relativity and cosmology. Highlights of the revision include the rise and fall of the fifth force, principles and applications of gravitational lensing, COBE's spectacular confirmation of the blackbody spectrum of the cosmic thermal radiation, theories of dark matter and inflation, and the early universe as a testing ground for particle physicists' unification theories, and much, much more. The ideal choice for a graduate-level introduction to general relativity, Gravitation and Spacetime is also suitable for an advanced undergaduate course.read more

Linear and nonlinear waves
TL;DR: The study of waves can be traced back to antiquity where philosophers, such as Pythagoras, studied the relation of pitch and length of string in musical instruments and the subject of classical acoustics was laid down and presented as a coherent whole by John William Strutt in his treatise Theory of Sound.

General covariance and the foundations of general relativity: eight decades of dispute
TL;DR: A review of the development of Einstein's thought on general covariance, its relation to the foundations of general relativity and the evolution of the continuing debate over his viewpoint can be found in this paper.
Journal ArticleDOI
Explanation and invariance in the special sciences
TL;DR: The notion of invariance has been used to resolve a number of dilemmas that arise in standard treatments of explanatory generalizations in the special sciences as mentioned in this paper, such as whether or not a generalization can be used to explain.

Generalized Curvature-Matter Couplings in Modified Gravity
TL;DR: In this article, a plethora of modified theories of gravity with generalized curvature-matter couplings are reviewed, where the explicit nonminimal couplings, for instance, between an arbitrary function of the scalar curvature R and the Lagrangian density of matter, induces a non-vanishing covariant derivative of the energymomentum tensor, implying non-geodesic motion and, consequently, leads to the appearance of an extra force.

The Quantum vacuum and the cosmological constant problem
Svend E. Rugh,Henrik Zinkernagel +1 more
TL;DR: The cosmological constant problem arises at the intersection between general relativity and quantum field theory, and is regarded as a fundamental problem in modern physics as mentioned in this paper, which is intimately connected to the vacuum concept in quantum field theories.
