special theory of relativity

Thân thiện

The scientist explains the special theory of relativity using a diagram of a light clock.

Definition

1. Noun:
   • A physical theory of relativity based on the assumption that the speed of light in a vacuum is a constant and the assumption that the laws of physics are invariant in all inertial systems: The special theory of relativity is a fundamental theory in physics, formulated by Albert Einstein, which describes the relationship between space and time for objects moving at constant velocity relative to each other, particularly at speeds approaching the speed of light.

Usage Examples

• Noun:
  • Einstein published his paper on the special theory of relativity in 1905.
  • Understanding the special theory of relativity is essential for modern physics.
  • The predictions of the special theory of relativity, such as time dilation, have been confirmed by experiments.

Advanced Usage

• "within the framework of the special theory of relativity": used to describe analyses or conclusions made using this theory's principles.
  • This phenomenon can only be explained within the framework of the special theory of relativity.
• "implications of the special theory of relativity": refers to the consequences and predictions derived from the theory.
  • The implications of the special theory of relativity revolutionized our concepts of space and time.

Variants and Related Words

• Special relativity (n): A common abbreviated name for the special theory of relativity.
  • The course covers both Newtonian mechanics and special relativity.
• Relativity (n): The broader scientific concept concerning the dependence of physical phenomena on the relative motion of the observer and the observed objects, which includes both the special and general theories.
  • Einstein's theory of relativity changed physics forever.

Synonyms

• Special relativity: The standard abbreviated synonym.
• Einstein's special theory: A descriptive synonym referencing its creator.

Related Phrases

• Principle of relativity: A foundational concept stating that the laws of physics are the same in all inertial frames of reference, which is a cornerstone of the special theory of relativity.
• Lorentz transformation: The set of equations in the special theory of relativity that relate the space and time coordinates of two inertial frames moving at constant velocity relative to each other.

Related Concepts

• General theory of relativity (n): Einstein's subsequent theory that extends the principles of special relativity to include gravity and acceleration.
  • While the special theory of relativity deals with uniform motion, the general theory of relativity describes gravitation.
• Time dilation (n): A key prediction of the special theory of relativity where time passes at different rates for observers in relative motion.
• Length contraction (n): Another key prediction where the length of an object moving at relativistic speed appears contracted to a stationary observer.
