Sir Isaac Newton`s theroy on gravitational attraction.

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

The construction of a consistent theory of quantum gravity is a problem in theoretical physics that has so far defied all attempts at resolution. Reviewed here are three major areas of research: gauge-theoretic approaches; quantum Regge calculus; and the

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