explanations given to you.It was reasonable and fair nomenclature at the time.lengthI laughed.realized that Jan is right. Well, maybe a laugh would be appropriate,
R.H.
Hmm, doesn't look like a laugh. Maybe an OMG! Meaning, you just
too, meaning "how could I have been so wrong!"You come up with your D'=D.sqrt[(1+Vo/c)/(1-Vo/c)], which isn'tcontraction but Doppler shift, which is dependent on the sign of yourYou say: "it's a Doppler shift".
Vo. LC is NOT so dependent. It would be a VERY strange universe if
it were.
And for sqrt(1-Vo?/c?)?
Isn't it a Doppler shift?
Yes, it's also a Doppler shift.
This is what Hachel calls the "internal Doppler effect".
Relativists call it the transverse Doppler effect, but the term is neither
fair nor pretty.
People didn't have relativity in order,
and they discussed the motion of electrons in terms of variable masses.
They discovered that the 'longitudinal mass' and the 'transverse mass'
of the electron were different.
It seemed quite reasonable at the time to extend the notion to light,
because the terminology was already current,
Jan
There is no need to talk about transverse mass, longitudinal mass, and other such joys.
It is NOT 'quantity of matter' or similar!
