''Galilean relativity ? IS below Paragraph about Einstein ? *********************************************************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 floorGeneralizing 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.''
PEOPLE WHO DO are more iImportant than people WHO SPEAK !PLEASE STOP SPEAK PLEASE DO !!I took kamera and I made TEST ! I FOUND THIS PROBLEM by TEST ( practica )

I FOUND THIS PROBLEM by TEST ( practica )Have you just tried to tell me not to speak to you , you have more important people to speak to?I have seen you before on another forum, you came on after me and did the same thing, I think you have read my ideas and understood the content, and now are claiming the ideas to be yours?. If they are genuine your ideas, then we have the more or less the exact same ideas, so of all the people in the world,I am the one who understands you and can put into English and have put into English.
DOUBLE SLIT EXPERIMENT My own explanation !
Are YOU from USA ? during my first test I spoke by telephone with ONE person He can confirm THIS DIALOGUE ( we were in shock ) !
