A while back I was involved in a discussion regarding the difference between the classic Doppler Effect equation and the Relativistic Doppler Effect equation explaining red/blue shift in stars.
I went looking for how to derrive both formulas and came across this interesting article that explains how there is actually no difference between the two.
My math skills are quite lacking, and I would be the wrong person to judge the paper's accuracy.
Accodring to the author, the commonly used formula for standard Doppler Shift is an approximation that is accurate enough for the low speed of sound wave propagation, but fails at higher speeds (presumably due to the exponentially increasing shift, but as some of the math is beyond me, I have just breezed the article so far).
I would very much like to know if it is correct, and was hoping some here (who's math has exceded the High School level) would also find the article interesting enough to read it and share their opinions on its accuracy (and maybe point out where the author went wrong if it is not).
