What is a dimension What is a dimension?

N a1, a2 ,.. in the number field fan. (a1,a2,..an) is called the n-dimensional vector on the number field f, that is, there are several components in the vector, it is multi-dimensional, that is, how many datum vectors in that space are orthogonal to each other, it is multi-dimensional.

Mathematically speaking, there is an n-dimension, which may tend to infinity. But in real life, a straight line is one-dimensional, a plane is two-dimensional, and a three-dimensional is three-dimensional, and that's it. At most, add one more time to become four-dimensional, but at the moment the human brain is not so powerful, only the great Einstein could do that.

Usually speaking, three-dimensional space refers to the usual space.

Geometry refers to the number of orientations that are independent of each other in space, usually space has three dimensions, planes or surfaces have two dimensions, and lines or curves have only one dimension

The ideal point is zero-dimensional.

The ideal straight line is one-dimensional.

The ideal plane is two-dimensional.

The space we live in is three-dimensional.

Relativistic space treats time as a dimension, so it is four-dimensional.

The true spatial dimension in string theory is ten.

But there's no need to understand this.

Mathematics is abstract and not real, it can have arbitrary dimensions, infinite dimensions.

What is a dimension? Do you understand?

The explanation of "Wei" in "Modern Han" is:

Basic concepts of geometry and space theory. Each factor that makes up space (e.g., length, width, height) is called one-dimensional, for example, a straight line is one-dimensional, a plane is two-dimensional, and ordinary space is three-dimensional.

My explanation: The space we live in is four-dimensional, as the previous ones said. But in fact, the total dimensionality of the universe is infinite, and only because human beings are limited in their ability to imagine three-dimensional space.

This introduces Einstein's general theory of relativity, in which the concept of space curvature appears, so that the multidimensional space is compressed within Planck's constant, which is an order of magnitude 10 (-34) meters, and the proton is an order of magnitude 10 (-15) meters, so the current technology cannot detect more than four-dimensional space.

The upstairs is good, so it's a good choice! Hehe.

A dimension is a dimensionality that is the number of independent parameters in mathematics.

Dimensions, also known as dimensions, are the number of independent parameters in mathematics. In the realm of physics and philosophy, it refers to the number of independent space-time coordinates.

Dimension 0 is a point and has no length. 1 dimension is the line, only the length. Dimension 2 is a plane that is made up of length and width (or curves) to form an area.

3 dimensions is 2 dimensions plus height to form a "volumetric surface". Although the average person is accustomed to the integer dimension, in fractals the dimension is not necessarily an integer, but a non-integer rational or irrational number.

The surrounding space has 3 dimensions (up and down, front and back, left and right), which can move up and down, southeast and northwest, and the movement in other directions is only represented by 3D space axes. Moving down is the same as moving up in a negative direction, and moving northwest is just a mix of westward and northward.

Fractional dimension:

In the 19th century, mathematicians discovered fractals, which created a new dimension, the "fractional dimension". As a result, people realize that dimensions are not just integers, but can also be fractions and even irrational numbers.

Professor Stephen Hawking, a famous British physicist, has this explanation: this is like a hair, which looks like a one-dimensional line from a distance, but under a magnifying glass, it is indeed three-dimensional; If you are faced with time and space, if you have a magnifying glass with a high enough magnification, you should be able to reveal other possible 4-dimensional and 5-dimensional spaces, and even 11-dimensional spaces.

An inclusion of the meaning of "attributes, scope, coefficients, affordability". Refers to different meanings in different objects.

Dimensions, also known as dimensions, are the number of independent parameters in mathematics. In the realm of physics and philosophy, it refers to the number of independent space-time coordinates.

Broadly speaking, dimensions are things"There is a connection"The number of abstract concepts....

From a philosophical point of view, people observe, think, and express something"Thinking perspective", abbreviation"Dimensions"。

Dimensions mean:

1. Philosophical implications;

The "thinking angle" from which people observe, think, and express something is referred to as "dimension". For example, when people observe and think about the "moon", they can describe it from the three perspectives of "content, time, and space" of the moon. It can also be described from the three perspectives of "carrier, energy, and information" of the moon. Zen Tell Mountain.

2. Mathematical meaning:

is the number of independent parameters in mathematics, also known as dimensionality.

3. Implications of Physics and Philosophy:

Refers to the number of independent space-time coordinates.

Dimension Description: 1 dimension is an infinitely long line with only length. 2D is a plane made up of length and width (or part of a curve).

3 dimensions is 2 dimensions plus height to make up the volume. Four-dimensional is divided into four dimensions in time and space, and it is often said that four dimensions refers to the transfer of objects on the time line. Four-dimensional space-time refers to three-dimensional space plus one-dimensional time.

Four-dimensional space refers to only four dimensions of space. The four-dimensional movement of the Yunyou rubber produces the five-dimensional. <>

Dimensions, also known as dimensions, are the number of independent parameters in mathematics. In the realm of physics and philosophy, it refers to the number of independent space-time coordinates. Dimension 0 is an infinitesimal point with no length.

1 dimension is an infinitely long line with only length. 2D is a plane that is made up of an area made up of length and width (or part of a curve). 3 dimensions is 2 dimensions plus height to make up the volume.

The 4 dimensions are divided into 4 dimensions in time and space, and people often refer to the transfer of objects in time.

To be precise, four-dimensional space-time refers to three-dimensional space plus one-dimensional time. Four-dimensional space refers to only four dimensions of space. Four-dimensional motion gives rise to five-dimensional.

From a philosophical point of view, the "thinking perspective" from which people observe, think, and express something is referred to as "dimension". For example, when people observe and think about the "moon", they can describe it from the three perspectives of "content, time, and space" of the moon. It can also be described from the three perspectives of the moon's "carrier, energy, and information".
