[net.followup] speed of light

There's an article in this week's Science magazine indicating that the
definition of length may become based on time in a new standard
expected to be adopted this fall.  The meter would be defined as the
length of the path traveled by light in a vacuum during a time interval
of 1/299,792,458 of a second.  Thus the speed of light would be defined
to be 299,792,458 meters per second and as measurement techniques
result in more accurate measures of the speed of light the length of
the meter would change, not the definition of the speed of light.
