A structured body of knowledge that systematically explains and predicts individual phenomena or facts based on coherent principles, often used in scientific research.
The conceptual framework created through logical reasoning and deduction that unifies various insights into a cohesive understanding, contrasting with practical application or experience.
A discourse or discussion about the reasoning and principles underlying a subject, wherein theoretical ideas are debated, often indicating a contrast between theory and practice.
A specific viewpoint or theory associated with particular scholars or fields of study, reflecting their unique interpretations and propositions regarding a topic.
Example:
その考えが彼の理論の基礎となっている。
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。
In the context of abstract reasoning, referring to concepts or ideas that are based on principles or assumptions rather than practical considerations.
Pertaining to a framework of understanding that exists in theory, without necessarily reflecting practical or empirical reality.
Describing a situation or assertion that is valid according to logical reasoning but may not align with practical application or experiences.
Indicating a standpoint that is derived from theoretical models or hypotheses rather than direct observation or evidence.
Pertaining to concepts, ideas, or principles that are based on theory rather than practical application.
Related to or grounded in an abstract framework or system of thought that interprets or explains phenomena.
Characterized by a focus on hypothetical scenarios or the exploration of possibilities as opposed to real-world implementation.
Example:
ギリシャ人たちは幾何学の理論的原形を作った。
A branch of physics that focuses on developing abstract models and theories to explain natural phenomena, often relying on mathematical frameworks rather than direct experimental validation.
The field of study that aims to derive fundamental laws of nature and predict new physical phenomena based on existing observations and theoretical approaches.
An area of physics that emphasizes the use of logical and mathematical reasoning to understand the principles underlying physical systems, often speculating about conditions not yet observed.
The discipline that involves the formulation and analysis of physical theories to understand the universe, contrasting with empirical approaches that prioritize experimental evidence.
Example:
アインシュタインにとって理論物理学は遊びのようなものだったが、そんな彼も税金の計算となるとからきし駄目だった。
