1905: Einstein publishes special relativity
In physics, the special theory of relativity, or simply special relativity, is a scientific theory of the relationship between space and time.
Why this milestone matters
Breakthroughs in physics usually change how later scientists ask questions. This milestone shaped the tools, models, or experiments that came after it.
The laws of physics are invariant (identical) in all inertial frames of reference (that is, frames of reference with no acceleration). This is known as the principle of relativity.
The speed of light in vacuum is the same for all observers, regardless of the motion of light source or observer. This is known as the principle of light constancy, or the principle of light speed invariance.
The first postulate was first formulated by Galileo Galilei (see Galilean invariance).
Historical context: Einstein publishes special relativity
In physics, the special theory of relativity, or simply special relativity, is a scientific theory of the relationship between space and time. In Albert Einstein's 1905 paper,
"On the Electrodynamics of Moving Bodies", the theory is presented as being based on just two postulates:
The laws of physics are invariant (identical) in all inertial frames of reference (that is, frames of reference with no acceleration). This is known as the principle of relativity.
The speed of light in vacuum is the same for all observers, regardless of the motion of light source or observer. This is known as the principle of light constancy, or the principle of light speed invariance.
The first postulate was first formulated by Galileo Galilei (see Galilean invariance).
