The condition or state of existing or being understood in relation to something else, emphasizing the interconnectedness or dependence of entities rather than viewing them in isolation.
A philosophical concept denoting that the properties or values of objects or phenomena are determined by their relationships with other objects or phenomena, rather than by absolute standards.
A principle in physics asserting that measurement and observation can vary depending on the observer's frame of reference, highlighting the relative nature of spatial and temporal constructs rather than an absolute reality.
A situation or agreement that involves two parties directly engaging with each other, without intermediaries, and where both parties hold equal standing in the interaction.
A relationship or interaction where two parties engage directly with each other, without the involvement of a third party, often implying an equal standing between them.
The concept of existence or value that is determined through comparison or relation to another element, highlighting the interconnectedness of entities rather than viewing them in isolation.
The state of being in opposition or facing each other, which suggests a dynamic interaction or conflict that arises from differing perspectives.
A theoretical principle asserting that the significance or nature of phenomena is reliant on relative positioning or context, emphasizing that measurements or experiences vary based on the observer's standpoint.
A fundamental theory in physics formulated by Einstein, which describes how the laws of physics remain consistent for all observers, regardless of their relative motion, and establishes the relationship between space and time as interconnected dimensions within a four-dimensional framework.
A scientific theory detailing that both time and space are not absolute entities but rather flexible, with time varying depending on the observer's state of motion, and mass being equivalent to energy, thus fundamentally altering our understanding of gravity as a curvature of spacetime.
A comprehensive framework in physics that revolutionizes our perception of the universe by asserting that measurements of time and space are relative to the observer's velocity, leading to profound implications for the nature of energy, mass, and gravity over significant distances or in strong gravitational fields.
Example:
アインシュタインという名から私達は相対性理論を連想する。
Describing a concept or condition that exists or is understood only in relation to something else, rather than in isolation.
Characterizing an aspect that varies based on comparisons with other factors or contexts, often highlighting the importance of perspective in understanding.
Pertaining to a viewpoint or measure that is contingent on external circumstances, contrasting with an independent or absolute evaluation.
Example:
「美しい」とか「醜い」といった言葉は相対的な用語である。
The velocity of one object as observed from another object in motion, highlighting the comparative nature of their speeds.
The speed of an object in relation to another moving object, emphasizing the interaction and movement between the two.
The difference in speeds between two moving bodies, defined from the perspective of one body observing the other.
