Show Rather Tell Einstein And Amateurs By SUSAN RATHER Einstein's theory of relativity has presented mankind with some provocative solutions to his questions about the nature of the THE solutions have influenced the lives the thinking of most while remaining somewhat of a mystery in to One reason for the aura of mystery which surrounds the theory is that its predictions are contrary to the logic of common and are difficult to though they have been proven valid in repeated scientific PROGRAMS at the Hansen Planetarium in Salt Lake or many of the science fiction books and give an enticing invitation to the study of Einstein's The invitation can be fol-lowed-up by the reading of books such as For The by James A. from which the information in this column was Centuries ago observers noticed that sound and light seemed to travel through the air at different As in a the farther away one is from a flash of the longer it takes for the noise of the ensuing thunder to be Experiments proved that the or of sound is about miles per while the velocity of light is miles per THE theory Einstein astounded scientists concerning light waves and their showed that they did not behave according to the laws thought to govern other physical As an assume that a stream of water flows at a speed of ten miles per hour relative to an observer standing on the In the water is a boat which is moving five miles per hour forward through the The total speed of the boat relative to the observer is found by adding the flow of the stream to the speed of the boat with the result of 15 miles per APPLYING the same mathematical assume that a is flying through space at a speed of miles per quite and is being observed by a person on the A spotlight attached to the rocket's nose is turned on and shoots a light wave forward at the speed of miles per second relative to the rocket's Logic would tell us that the light wave is then travelling the sum of the two or miles per relative to the earth According to Einstein's theory this is not the The light wave can travel only at miles per second relative to an the head of the light wave is located in two different depending upon who does the Not that it just to be located but that it actually Something about the relativity of the fourth next |
