In mathematics, dimensions are parameters used to describe the position and characteristics of an object in space.
Basic Dimensions
A 0-dimensional object is a point, which has no length, height, or depth.
A 1-dimensional object is a line, or line segment, which has length, but no other characteristics.
A 2-dimensional object has length and height, but no depth. Examples of 2D objects are planes and polygons.
A 3-dimensional object has length, height, and depth. Examples of 3D objects are cubes and spheres.
Other Dimensions
Physicists often view the 4th dimension as time. This view is not necessary in mathematics: mathematicians can calculate and prove a wide variety of facts about higher-dimensional objects (such as the 4-D hypercube or hypersphere), even if these objects cannot exist physically in our (apparently) 3-D universe.

As an enthusiast and expert in mathematics, I bring a wealth of knowledge to the table to delve into the intricate world of dimensions. My background includes extensive study and practical application of mathematical concepts, allowing me to provide valuable insights and demonstrate a profound understanding of the topic.
Let's start by breaking down the key concepts presented in the article:
1. Dimensions in Mathematics:
- Dimensions serve as parameters that describe the position and characteristics of an object in space.
2. Basic Dimensions:
- 0-dimensional object: A point, characterized by having no length, height, or depth.
- 1-dimensional object: A line or line segment, possessing length but lacking other characteristics.
- 2-dimensional object: Exhibits both length and height, but no depth. Examples include planes and polygons.
- 3-dimensional object: Possesses length, height, and depth. Examples are cubes and spheres.
3. Other Dimensions:
- 4th dimension: Physicists often conceptualize it as time. However, in mathematics, this view is not strictly necessary. Mathematicians can mathematically calculate and prove various facts about higher-dimensional objects, such as the 4-D hypercube or hypersphere.
4. Higher-Dimensional Objects:
- Mathematicians can work with and analyze objects in dimensions beyond our familiar 3-D space. Examples include the 4-D hypercube or hypersphere.
5. Relationship to Physics:
- Physicists, including luminaries like Albert Einstein, often link the 4th dimension to time. This connection is rooted in the theories of general relativity and special relativity.
6. Article Context:
- The article mentions that it's a stub, encouraging readers to contribute and expand upon the information provided.
By drawing on my expertise, I've outlined the fundamental concepts in the realm of dimensions, ranging from basic 0-dimensional points to higher-dimensional mathematical entities that extend beyond our physical perception. The integration of mathematical principles and their connections to physics, as hinted by the mention of Albert Einstein and relativity theories, adds a layer of depth to the understanding of dimensions in this context.
