The Rise of Einsteinian Special RelativityIn 1905, Einstein's Theory of Special Relativity was proposed. The reason that it is so "special" is because it was part of the more complex and extensive Theory of General Relativity, which was published in 1915. His theory reshaped the world of physics when it contradicted all previous laws of motion erected by Galileo and Newton. By mathematically manipulating these previous laws of motion, physicists in the nineteenth century were able to explain such phenomena as the flow of the ocean, the orbits of planets around the sun, the fall of rocks, and the random behavior of molecules in gases. At first, Einstein faced great opposition when he came up with his radical new theory because the previous laws of motion proposed by Galileo and expanded upon by Newton had remained valid for over two hundred years. However, it wouldn't be long before the "cement" in the foundation of Newtonian and Galilean physics would begin to crumble.Galileo had determined in 1608 that merely addition and subtraction could calculate relative speeds. Suppose that an observer stands on the side of the highway, and they watch two cars approach each other at 30 and 40 miles per hour. If they were to as
Two events that are observed to be simultaneous in one reference frame will not be simultaneous in any other reference frame that is moving with respect to the first frame. The difference, according to Newton and Galileo, would only be about 1 part in 10,000 since the earth moves slowly relative to the speed of light. Furthermore, since the aether was at rest in absolute space (according to Newtonian physics), anybody who is stationary will measure the same light speed in all directions, while anybody in motion will measure different light speeds. ; the clock on the rocket would read less than 3:00 P. Thus, this slowing in time works both ways. Newton's absolute space was the space of everyday experience with its three dimensions: east-west, north-south, and up-down. In Einstein's Theory of Special Relativity, a reference frame is simply the platform or framework from which one makes observations. It just so happens that two lightning bolts strike the train; one strikes the front and one strikes the rear. "This method of thinking would have been acceptable up until 1881. No matter what direction a bird flies, it always has the same maximum speed. We all, regardless of our motion, will agree on the length, breadth, and height of an object, so long as we make sufficiently accurate measurements. Speed is an example of how much distance is covered per unit time; therefore, in order to obtain speed, one needs distance and time. Because the light from the front of the train reached Brett first, and light travels at the same speed all the time; Brett concludes that the lightning bolt that struck the front of the train occurred before the lightning bolt that struck the rear of the train.
