Title: Doppler's mechanism inside Michelson Morley
Post by: marzosia2 on 30/03/2016 14:48:00
Distance " d " exist because sensor is making rotation CW or CCW
(below model please confirm in books - physics ). I showing here only to help
You understand it is not new information  Sensor's X,Y are changing during rotation   )



( very old Doppler's  mechanism  inside famous test HOW   WORKS LORENZ's REDUCTION
Did He evaluate DOPPLER or ZERO ? )

distance "d" for sensor and for source it is not the same "d"  ! R1<R2 ! )

the same problem we can evaluate for Y axis

My Question is respect to what Earth is making rotation ?
respect to stars ? or respect to stationary space ?  Why I see Doppler ?
what will be if the Earth will not making rotation ? ( absolute zero motion ? )

 physics's history...

" Galilean relativity states that the laws of motion are the same in all inertial frames. Galileo Galilei first described this principle in 1632 in his Dialogue Concerning the Two Chief World Systems using the example of a ship travelling at constant velocity, without rocking, on a smooth sea; any observer doing experiments below the deck would not be able to tell whether the ship was moving or "

1861 J. C. Maxwell, published his theory of electromagnetic fields and radiation,which shows that light has momentum and thus can exert pressure on objects.

 Galilean relativity ?*
Imagine a person inside a ship which is sailing on a perfectly smooth lake at constant speed. This passeneger is in the ship's windowless hull and, despite it being a fine day, is engaged in doing mechanical experiments (such as studying the behavior of pendula and the trajectories of falling bodies). A simple question one can ask of this researcher is whether she can determine that the ship is moving (with respect to the lake shore) without going on deck or looking out a porthole.
Since the ship is moving at constant speed and direction she will not feel the motion of the ship. This is the same situation as when flying on a plane: one cannot tell, without looking out one of the windows, that the plane is moving once it reaches cruising altitutde (at which point the plane is flying at constant speed and direction). Still one might wonder whether the experiments being done in the ship's hull will give some indication of the its motion. Based on his experiments Galileo concluded that this is in fact impossible: all mechanical experiments done inside a ship moving at constant speed in a constant direction would give precisely the same results as similar experiments done on shore.
The conclusion is that one observer in a house by the shore and another in the ship will not be able to determine that the ship is moving by comparing the results of experiments done inside the house and ship. In order to determine motion these observers must look at each other. It is important important to note that this is true only if the ship is sailing at constant speed and direction, should it speed up, slow down or turn the researcher inside can tell that the ship is moving. For example, if the ship turns you can see all things hanging from the roof (such as a lamp) tilting with respect to the floor
Generalizing these observations Galileo postulated his relativity hypothesis:
any two observers moving at constant speed and direction with respect to one another will obtain the same results for all mechanical experiments   
(it is understood that the apparatuses they use for these experiments move with them).
In pursuing these ideas Galileo used the scientific method (Sec. 1.2.1): he derived consequences of this hypothesis and determined whether they agree with the predictions.
This idea has a very important consequence: velocity is not absolute. This means that velocity can only be measured in reference to some object(s), and that the result of this measurment changes if we decide to measure the velocity with respect to a diferent refernce point(s). Imagine an observer traveling inside a windowless spaceship moving away from the sun at constant velocity. Galileo asserted that there are no mechanical experiments that can be made inside the rocket that will tell the occupants that the rocket is moving . The question ``are we moving'' has no meaning unless we specify a reference frame (``are we moving with respect to that star'' is meaningful). This fact, formulated in the 1600's remains very true today and is one of the cornerstones of Einstein's theories of relativity. 

My Question
I 'm able make 3D test inside ship ?
what I'm testing ? absolute motion ?

Light = mechanical experiment - EM preasure is pushing objects

Exist C+ V ? not exist ?  ABSOLUTE ZERO DOPPLER it is Important information ?
I'm moving or not ?
