Abstraction意思

"Abstraction" is a term that can have different meanings depending on the context in which it is used. Here are some common definitions:

  1. In art and design, abstraction refers to the process of simplifying or distilling a form or idea into its essential qualities, often by removing recognizable details or by focusing on the shape, color, texture, and form of an object. This can result in a work of art that is not representational or realistic, but rather focuses on the visual elements themselves.

  2. In philosophy, abstraction is the process of recognizing or isolating a common feature or characteristic from specific instances or objects. For example, the concept of "redness" is an abstraction that can be applied to many different objects that are red, regardless of their specific shape, size, or material.

  3. In computer science, abstraction is the process of hiding the details of how something works and only showing the essential features or functions. This is done to make it easier to use or understand a complex system, and it is a fundamental concept in software design and programming.

  4. In mathematics, abstraction is the process of focusing on the properties that are common to a class of objects, rather than on the specific characteristics of individual objects. This can lead to the development of general principles or theories that apply to a wide range of mathematical objects.

  5. In psychology, abstraction is the ability to extract the common features from a number of similar objects or experiences, and to recognize these features in new situations. This is an important aspect of learning and cognition.

  6. In music, abstraction refers to the process of focusing on the formal elements of music, such as melody, harmony, rhythm, and timbre, rather than on the emotional or narrative content of a piece.

  7. In literature, abstraction is the process of focusing on the formal qualities of a text, such as its structure, language, and style, rather than on its content or meaning.

In all of these contexts, abstraction involves the identification and separation of essential qualities or features from the specific, concrete details of a particular situation or object.
