Provides a simple introduction to the law for which Newton is best known.

An online journal with articles on advances in the theories of gravity.

A brief explanation of the search for a quantum theory of gravity, including links to sites on topological field theories.

A site maintained by Cambridge University on advances in quantum theories of gravity.

Discusses in simple terms the problem of constructing a quantum theory of gravity.

The book "Knots and Quantum Gravity" is the proceedings of a conference held at U.C. Riverside on May 14-16th, 1993. It is now available for free in Postscript format.

A review of the spin foam formulation of quantum gravity.

An assessment is offered of the progress that the major approaches to quantum gravity have made towards the goal of constructing a complete and satisfactory theory. The emphasis is on loop quantum gravity and string theory, although other approaches are discussed.

An article at Astronomy Today.

The construction of effective Hamiltonians arising from Loop Quantum Gravity and incorporating Planck scale corrections to the dynamics of photons and spin 1/2 particles is summarized.

After a brief introduction to classical and quantum gravity we discuss applications of loop quantum gravity in the cosmological realm. This includes the basic formalism and recent results of loop quantum cosmology.

This is a summary of a talk delivered at the workshop, "Quantum gravity in the Southern Cone II".

This is a pedagogical introduction to the treatment of general relativity as a quantum effective field theory.

A review of modern approaches to quantum gravity.

A brief introduction is given to the methods of effective lagrangians. The emphasis is on a summary of the overall picture, using a simple model of quantum gravity.

A review of material presented at 1998 conference on quantum cosmology.

This postscript file includes a review of the present theoretical attempts to understand the quantum properties of spacetime.
