Michelson-Morley Experiment & Black-Body Radiation: Modern Physics
Michelson-Morley Experiment
Phenomenon: The Michelson-Morley experiment aimed to determine the velocity of the Earth in the frame of the ether, based on the characteristics attributed to light. The experiment revealed that the speed of light is constant and independent of the observer’s motion and the motion of the source, i.e., not dependent on the reference system. This conflicted with the classical conception of movement.

Translation Equivalence and Processes: A Comprehensive Analysis
Types of Equivalence
Koller outlines five types of equivalence to illustrate the different dimensions of equivalence in translation:
- Denotative Equivalence: This type of equivalence relates to the equivalence of the extralinguistic content of a text, also known as “content invariance.”
- Connotative Equivalence: It pertains to lexical choices, especially between near synonyms, and is sometimes referred to as “stylistic equivalence.”
- Text-Normative Equivalence: This type is linked to different text types
