An overview of why Einstein added an extra term in general relativity, and why it is still examined.

Covers current and past projects in experimental gravitational physics using Drag-Free Satellites including the Relativity Gyro, Equivalence Principle, and LISA.

A textbook for relativistic quantum mechanics is presented. The Dirac equation is dealt with in detail.

An article by Vincent Sauvé elaborating upon a materialist view of the absolute and relative nature of time.

Provides information on the history, experiments and paradoxes of relativity.

Sean M. Carroll's lecture notes from a one-semester graduate-level course he taught at MIT in 1996. Notes are in postscript format.

Easy to understand 'debunking' of some common misconceptions about cosmology and relativity and why they are wrong.

Research includes detection of periodic gravitational radiation from relativistic astrophysical objects, investigation of infra-low-frequency variations of Terrestrial gravity field in the role of crystal growing and compound formation, and investigation of time variations of Terrestrial inertial field and the geophysical consequences.
