The Theory of Relativity, developed by Albert Einstein in the early 20th century, comprises two interlinked theories: Special Relativity and General Relativity. 1. **Special Relativity (1905)**: This theory addresses the physics of objects moving at constant speeds, particularly those moving close to the speed of light. It introduces two key postulates: - The laws of physics are the same for all observers, regardless of their relative motion.

The World Year of Physics 2005 was a global celebration of physics, commemorating the 100th anniversary of Albert Einstein's groundbreaking contributions to the field, particularly his theories of special relativity and the photoelectric effect. The initiative aimed to elevate public awareness and appreciation of physics and its significance in understanding the universe, as well as its technological and social impacts.
