If the angular momentum in each direction is equal, does that mean zero total; or does one not influence the other?



I don’t have the depth of knowledge to look at these responses and say, this or that point is wrong. The best I can do is comment on what each contributor says to me.

Tavel: I have the impression that he was in a hurry to move on; or perhaps thought: “That’s good enough for the plebs”. If I could spot a sin, it would one of omission.

Bachmann: He address the subject of angular momentum and magnetic moment. He leaves the question of magnetic moment a bit vague, but one can’t expect too much in a brief response. He was obviously listening to the question, because he says: “It is analogous to the spin of a planet…”. His final comment is an interesting one; I wish he had said a bit more about “why”.

Stenger: My only objection to his opening paragraph is that he gives the impression that quons are little solid objects. On the plus side, he considers angular momentum.

His third paragraph has some good information, but he fails to clarify any connection between, for example, the Pauli exclusion principle and spin.

His final sentence has a degree of profundity, but leaves me wanting to ask him to explain why.

I guess that what I am saying is: “I don’t know which you have selected as being the right one. I think I would extract most from a combination of points from all three. If I have to select one, I think it must be Stenger, but it’s a shot in the dark. I’ll stick with bits of all three.

You need to define influence? If you mean do they sum on the containing body (like the propellers) then yes they do

I will give a warning however if you are going to mix them makes sure your classical angular
momentum is the relativistic one not the plain schoolyard version.


Stenger was the only one who got exactly right and his last statement is definitely worth thinking about

We cannot detect any absolute movement of a field; only relative movements within the field?

AT FIRST we MUST ASK ABOUT GALILEO
( FATHER for RELATIVE MOTION )

CAN WE SOLVE HIS PROBLEM ?

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.

EXIST SIMPLE MECHANICAL EXPERIMENT
PERSON INSIDE SHIP IS ABLE RECOGNIZE CONSTANT MOTION !!!


THEORY :
James Clerk Maxwell, in 1861–64, published his theory of electromagnetic fields and radiation, which shows that light has momentum and thus can exert pressure on objects.


SI units system :
ENERGY/SPACE = [ Joul / cubic meters = Newton *meter / cubic meters = N/m^2 ]


How big force is registering left /right wall ( intensity ? )
1 NOT EXIST C+V !
2 where 3D signal started?
3 where are walls ?







THE WALLS ARE REGISTERING FORCES !!
IT IS TYPICAL PREASURE PROBLEM !!




STUDY BELOW !!!

GALILEO ASLO MADE MISTAKE
IF WE SPEAK ABOUT NATURAL FALL LAW


IN UNIVERSE EXIST MANY STARS ( moon = mirror )

HOW BIG PREASURE IS PUSHING EARTH ?

HOW BIG FORCE IS PUSCHING ELECTRON ?


WHY WE SEE WAVE IN YOUNG EXPERIMENT ??!!!











DUALISM ????? NO !!!!!!
( NEWTON's idea is possible !)
