: The two Doppler shifts are the "same". If v << c,
: the relativistic formula reduces to the non-relativistic one.
:
: Your posting seems to imply that these are two different
: expressions that need to be used depending on relative velocity.
:
: They aren't. The relativistic one reduces to the non-relativistic
: one in the the limit that v << c.

What ARE you smoking, Anderson? What IS the limit of v << c?
Negative infinity, perhaps?
