Plan of the Course Special theory of relativity is a part of graduate physics course but keep deep concepts of relative motions. In the begining of this course some live example are taken to explain the relative motion and later frame of references are explained based on it. To explain the relativistic effects at the speed of light some artistic view of the events are tried to explain the situation that how first observer observe the event and then using some relationship explained that how it will appear by the second observer. Precautions in special theory of relativity: To understand it in a clear way it is better to observe the meaning and visualize the frame of reference. If you read and understand it you will get the clear idea. Some numerical problems are added here to get the insight about real situations. There are some points that should be very clear these are; Frame of reference Observer event Now frame of reference can be anything where a person observe any event, for an example relative motion between two cars. As you know, and definitely you have observed it in your childhood, when you were travel by the car or superfast trains. You have observed that when you overtake a car it passes slowly but the car which comes toward you cross your car very fast. Or plants, tree moves in opposite direction with the same speed as you are. READ ALSO: #1. Quantum Mechanics Course #2. Electrodynamics Course
