Abstract

I will describe the treatment of gravity as a quantum effective field 
theory. This allows a natural separation of the low energy quantum effects 
from unknown high energy contributions. Within this framework, gravity is 
a well behaved quantum field theory at ordinary energies. In studying the 
quantum corrections at low energy, the dominant effects at large distance 
can be isolated, as these are due the propagation of massless particles of 
the theory and are manifested in the non-analytical contributions from 
diagrams. The methodology is illustrated by the calculation of the 
one-loop quantum corrections to the gravitational interaction of two heavy 
masses.
