1600 Galilean relativity /Natural Fall Law
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.
1901 P. N. Lebedev EXPERIMENTAL EXAMINATION OF LIGHT PRESSURE
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.

1600!!*********************************************************
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. ***************************************************************
WE HAVE AIRPLANE A and B
WE HEVE THE SAME INSTRUMENT (BULB---CAMERA)
WE MAKING THE SAME EXPERIMENT
HOW BIG FORCE IS PUSHING CAMERA ?
the same or not ?
the SAME EXPERIMENT AND NOT THE SAME RESOULT
WHAT IS THE REASON ?
1600 GALLILEO
250 YEARS LATER....
1861 MAXWELL
EINSTEIN SUPPORTED HIS THEORY ON GALILEO ?
FULL SCREEN > CLICK durning my work 2012 - 2015 I made many tests
I waiting for INTERNATIONAL help ( we need repeat many new
experiments ) and write new physics
ONLY TEAM WORK is important ( History is learning US that not exist Single person smart like EINSTEIN ... it is OUR UNREAL VIsION not science !
