(false threat of communism reaching North America) was a hoax, and called for an end to racism (Golden 22).Shortly after graduation Einstein began to ponder about the universe. While living in Germany, he composed his first of two relativity theories; The Special Theory of Relativity (Golden 23). "The Special Theory of Relativity deals with phenomena that becomes noticeable near the speed of light, and reference frames that are moving at a constant velocity" (Gundersen 386). Einstein suggested that speed, length, and time are not constant, they are relative to one?s perspective (Sagan 544).To clarify this Einstein would consider this thought experiment: A train is moving at a constant velocity. There is an observer, A, standing in the embankment. He has two colleagues, B and C, standing equal distances from either side of him. Both, B and C, have a flashlight, and turn them on. Observer A sees them at the same times and determines that they occurred at the same time, because light travels at a constant velocity and observers B and C are equal distances from him. Another observer, X, is standing on the middle of the train and happens to be precisely at point A when observer A sees both flashes. Of course, observer X will see them at the same time too, but he wishes to calculate whether or not they were turned on simultaneously. He can do this with the aid of another observer, Y, who happens to be at point B when the light is turned on there. Observer Y sees the light, and marks on his ruler point Y. At this point neither observer X nor A has seen the lights turn on. The train continues moving and one moment later Movement Y Train X Train Movement B Embankment A Embankment Cobserver X arrives at point A, and they both see the light flashes (Bohm 56-58).Movement Y Train X Train Movement...
