Default Galileo (NOT Einstein) is inventor of Second postulate of Relativity


John Gilmer wrote:
Special Relative postulates that the speed of light will be the same to ALL
observers regardless of how fast they are going relative to the light
source.

I don't think Galileo even KNEW what the speed of light was other than being
"very fast."

----------------------------------------------------------------
There are two postulates of relativity.
One is about speed of light is constant.
The second one was given Galileo in in 1632 in his book , DIOLOGUE.
NOW AFTER 273 in 1905 EINSTEIN QUOTED THE SAME IN his Special Theory
of Relativity.

Einstein did not acknowldge, Galileo's work and called it as his own
invension.
I mean Galileo must be given credit for the same.
I have given the link below which discuss both the postulates.


Thus should Galileo be given credit for doing pioneering work in the
field of SPECIAL THEORY OF RELATIVITY.
It is the basic question.
See the references below.

The two postulates are quoted in section

§ 2. On the Relativity of Lengths and Times
The following reflexions are based on the principle of relativity and
on the principle of the constancy of the velocity of light. These two
principles we define as follows:--
1. The laws by which the states of physical systems undergo change are
not affected, whether these changes of state be referred to the one or
the other of two systems of co-ordinates in uniform translatory motion.

Any ray of light moves in the ``stationary'' system of co-ordinates
with the determined velocity c, whether the ray be emitted by a
stationary or by a moving body.

So whatever I have written is based upon these facts.
