What is a metric?
· Roughly speaking, a metric is a function ds2
describing the distance between two points in a set
of events S
· Distance = the length of the
shortest curve between two points
· The metric of the unit sphere
X(, ) = (sin cos, sin sin, cos)
(arc length on a meridian):
d2 = d2 +sin2 d2
Einstein's field equations
· 10 nonlinear PDEs
