Special Relativity, developed by Albert Einstein, revolutionizes our understanding of time, space, and velocity. It introduces the constancy of the speed of light and the relativity of time and space measurements. The theory's implications extend from the Lorentz Transformations to practical applications in GPS and particle physics, underpinning much of contemporary science and technology.

Albert Einstein developed the theory of Special Relativity, which fundamentally changed our understanding of time, space, and velocity
Principle of Relativity
The Principle of Relativity states that the laws of physics hold true in all inertial frames of reference
Invariance of the Speed of Light
The Invariance of the Speed of Light postulate asserts that the speed of light in a vacuum is a universal constant
Special Relativity deals with constant velocities and does not account for gravity, while General Relativity includes accelerated motion and the effects of gravity
The Lorentz Transformation equations allow for the translation of physical quantities between different inertial frames of reference
The Lorentz factor is essential for explaining time dilation and length contraction at high velocities
Special Relativity predicts that time and space are relative and can be affected by the velocity of the observer
The Michelson-Morley experiment provided evidence for the constancy of the speed of light and disproved the existence of the ether
The Global Positioning System (GPS) incorporates corrections based on Special and General Relativity to maintain precise location tracking
Special Relativity is applied in particle accelerators to study high-speed particle interactions
Special Relativity is used in medical treatments, such as proton therapy, to accurately target tumors while minimizing damage to surrounding tissue

Invariance of Physical Laws
Special Relativity asserts that physical laws are the same in all inertial frames, no preferred state of motion exists.
01
Speed of Light Constant
According to Special Relativity, light speed in vacuum is constant at ~299,792 km/s, unaffected by motion of source or observer.
02
Relativity of Simultaneity
Events simultaneous in one inertial frame may not be simultaneous in another, due to the relative motion of observers.
