Modern physics is the study of the two great revolutions in physics - relativity and quantum mechanics. . Galilean Relativity. . . All inertial reference frames are equivalent! Another way of stating this principle is that . Albert Einstein. A portion of Einstein’s fame came when he formulated Special Relativity.. He came up with this theory by simply performing thought experiments. He wondered what would happen if you travelled at the speed of light. He started with the most basic principles of physics and worked up from there…. Grigore. . Rosu. and Andrei Stefanescu. University of Illinois, USA. Matching Logic . Reachability. - Goal -.

The principle of relativity requires that . if the laws of physics are to be the same in every inertial reference frame, the quantities on both sides of an = sign must undergo the same Lorentz transformation so they stay equal. . We already know that the language of the machine is . binary. – that is, sequences of 1’s and 0’s. But why is this? . At the hardware level, computers are streams of signals. These signals only have two states of interest, high voltage and low voltage. . We already know that the language of the machine is . binary. – that is, sequences of 1’s and 0’s. But why is this? .
