Abstract
Einstein’s general theory has at its heart an equation that, like Poisson’s equation, relates the gravitational field of a distribution of matter to its energy density. The quantity that encodes energy density in special relativity is a symmetric two-index tensor called the energy-momentum tensor. We introduce it first in the simplest case of a noninteracting distribution of particles, and then extend the definition to fluids and to electromagnetic fields.
