Devoted to the history of general relativity, this text provides reviews from scholars all over the world. Many of the papers originated at the Third International Conference on the History of General Relativity, held at the University of Pittsburgh in the summer of 1991. Topics covered include: disputes with Einstein; the empirical basis of general relativity; variational principles in general relativity; the reception and development of general relativity; and cosmology and general relativity.

A broken pilot falls for a man who might be a walking weapon. They may need to save far more than each other. A mysterious distress call draws the crew of the Hermes to what appears to be an empty, drifting ship. Empty, except for the gore-spattered corridors and one survivor locked in a holding cell. Drawn to the traumatized man, the crew's comm officer, Isaac Ozawa, makes Turk his responsibility, offering him kindness and warmth after the horror he experienced. Turk longs for Isaac, a desperate, hopeless ache he'll always carry with him. But Turk's brain harbors dangerous secrets, a military experiment gone wrong. When an amoral, power-hungry admiral kidnaps Isaac to convince Turk to become the weapon he's hungered for, it will take Turk's strength, the Hermes crew's ingenuity, the enigmatic Drak'tar's help, and Isaac's own stubborn will to save them.

The Feynman Lectures on Gravitation are based on notes prepared during a course on gravitational physics that Richard Feynman taught at Caltech during the 1962-63 academic year. For several years prior to these lectures, Feynman thought long and hard about the fundamental problems in gravitational physics, yet he published very little. These lectures represent a useful record of his viewpoints and some of his insights into gravity and its application to cosmology, superstars, wormholes, and gravitational waves at that particular time. The lectures also contain a number of fascinating digressions and asides on the foundations of physics and other issues.Characteristically, Feynman took an untraditional non-geometric approach to gravitation and general relativity based on the underlying quantum aspects of gravity. Hence, these lectures contain a unique pedagogical account of the development of Einstein's general theory of relativity as the inevitable result of the demand for a self-consistent theory of a massless spin-2 field (the graviton) coupled to the energy-momentum tensor of matter. This approach also demonstrates the intimate and fundamental connection between gauge invariance and the principle of equivalence.
