##### Grover Swartzlander- ARE WE ABLE MEASURE MOTION ?
« on: 30/12/2015 18:13:59 »
Basic Informations (physics's history ) :

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.

1901   EXPERIMENTAL EXAMINATION OF LIGHT PRESSURE  P. N. Lebedev

2011 Grover Swartzlander first began to examine a revolutionary concept in optical physics after studying the flight of a moth. He watched the animal use its wings to create lift, which led to flight. Swartzlander asked a simple question: Could light be used to create the same effect?

SOURCE  ))))))))))))       WING >>> 30 km/s

SOURCE )))))))))))))       30km/s <<< WING

How big aerodynamic force will register wing ?

BELOW EXAMPLE I SHOWED ONLY TO EXPLAIN IDEA
Distance D is constant !
SUN's power is constant !      What about L1,L2,L3 ?

Person inside rocket TURNED ON BULB

situation A nothing happen
situation B/C  The rocket slowing down

When and Why  we have situation A ?
When  and Why we have situation B/C ?

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.

?????
MAROSZ(me) we are mowing respect to own OLD position this fact we can easy mesure ! Dynamica it is absolute frame I showing rocket without windows and person inside !

PHYSICS's HISTORY

1600  Gallileo relativity hypothesis and   Naturall Fall Law    ????????????????
1686  Newton ( Gravitation Law ) Grav. mass def.  F = ma ( Inertial Mass )
1861  Maxwell ( EM radiation problem  ) ????????????????????
1905 - Einstein's target was  rope all old  facts in one

2012 Marosz ????????

BELOW MY OWN IDEA ( my own opinion  I waiting for YOUR )
Motion is absolute ! because EM preasure is ABSOLUTE !
point in space where I was and where the source started 3D signal
it is not real object ! this point is not moving with me and my coordination system
I no need other objects around my eyes to evaluate EM preasure
preasure from my own source is very nice tool I can read motion
