Flashcards
What is the fundamental principle of special relativity?
What is the fundamental principle of special relativity?
The laws of physics remain the same regardless of an observer's motion. Imagine a train car with lights turned on inside. Whether the car is stationary or moving at constant speed, the light inside will always travel at the same speed relative to the passengers.
When was special relativity proposed?
When was special relativity proposed?
September 26, 1905. This marked a significant moment in the history of physics.
What triggered the development of special relativity?
What triggered the development of special relativity?
It arose from the incompatibility between Newtonian mechanics and Maxwell's equations of electromagnetism. The two theories couldn't be reconciled, leading to the need for a more fundamental theory.

Study Notes
Foundations of Special Relativity
- The special theory of relativity is based on the principles of physics that apply uniformly across all inertial frames of reference.
- Originally proposed in 1905 by Albert Einstein, marking a significant shift in our understanding of physics.
- The development of special relativity stemmed from inconsistencies between Newtonian mechanics and Maxwell's equations, particularly regarding the behavior of light.
Core Postulates
- The theory is underpinned by two fundamental postulates:
- The laws of physics are the same for all observers in uniform motion relative to one another.
- The speed of light in a vacuum is constant and independent of the motion of the light source or observer.
Historical Context
- Einstein's pioneering work was documented in his paper titled "On the Electrodynamics of Moving Bodies."
Key Experimental Findings
- The Michelson-Morley experiment provided significant evidence against the existence of the hypothesized luminiferous aether, supporting the concepts of special relativity.
Bridging Theories
- Special relativity reconciled the incompatibility between Newtonian mechanics and Maxwell’s equations, addressing the nature of electromagnetic phenomena.
Relationship Between Space and Time
- In special relativity, space and time are interwoven into a single continuum known as spacetime, demonstrating that measurements of time can vary depending on the relative motion of observers.
Constant Velocity of Light
- According to special relativity, the speed of light in a vacuum is approximately 299,792 kilometers per second (or about 186,282 miles per second), and it remains constant for all observers, irrespective of their motion.
