From: spudnik on 4 Mar 2010 00:56 the doppler effect is just a shift of frequency, not the speed of either sound or light; such effects are pronounced in the bowshock of a moving object, naturally. what instrument is used to measure permittivity & permeability, thus to "find" the speed of light?... taht speed was ucovered by Ole Roemer, observing the moons of Jupiter (not Galileo, of course). sound may not travel in a vacuum, but there is no vacuum, in the first place; vacuum is a verb, even though Pascal thought that he had discovered a perfect "plenum." there are no phonons; there are no photons; there is no *in vacuuo*; "there are no electrons" -- death to the lightcone! > The speed of light is found from two physical constants arising from > Maxwell's travelling wave formula.

D'Arsinval?... the Fourth Muskateer, Fresnel? pretty sad, for a teacher of Einstien to be so adumbrated. > >> Minkowksi space time? thus: hey, so did the epicycle for the precession of the equinoxes! http://quest.nasa.gov/galileo/Galileo-QA/Gravity_Effect/Gravity_Assist.1 > and the Sun passes the planet, a visual effect is created that the > planet is moving backwards to form an ellipse.

Argumental oscillations had already appeared, around 1919, in the pioneering work of Barkhausen and Kurz on the generation of microwaves. They noted that oscillating electrons, interacting with the high frequency electromagnetic field in the tubes they had constructed, spontaneously organized themselves into bunches, moving in equal phase with http://21stcenturysciencetech.com
