Special Relativity Fundamentals

Study Notes

In classical physics, Galileo developed the concept of inertial reference frames, stating that measurements of velocity depend on the reference frame adopted.
Inertial reference frames are assigned to objects moving with constant velocity, including zero velocity if at rest, and each frame has its own set of axes and a clock to measure time.
Albert Einstein built upon Galilean relativity, wondering what would happen if an object moving close to the speed of light was assigned as the inertial reference frame.
Special relativity comprises two postulates: the laws of physics are the same in every inertial reference frame, and the speed of light in a vacuum is the same in every inertial reference frame.
The speed of light (c) is a constant used in numerous equations and is a fundamental law of physics, making it the universal speed limit.
The first postulate implies that the laws of physics are the same everywhere, regardless of the observer's relative motion.
The second postulate states that the speed of light is the same for all observers, regardless of their relative motion.
The speed of light is always measured as 300 million meters per second, regardless of the observer's motion, as verified by experiments.
Time is relative and flows at different rates for different observers, which is a fundamental concept in special relativity.
Special relativity has been experimentally verified countless times with remarkable precision, and is a fundamental aspect of our understanding of the universe.
