Abstract
We show by an almost elementary calculation that the ADM mass of
an asymptotically flat space can be computed as a limit
involving a rate of change of area of a closed 2-surface. The
result is essentially the same as that given by Brown and York.
We will prove this result in two ways, first by direct
calculation from the original formula as given by Arnowitt,
Deser and Misner and second as a corollary of an earlier result
by Brewin for the case of simplicial spaces.
