Observing and Experiencing our Own Reality:
A detailed 3D geometric model of a 600-cell tetrahedral complex.
1.) Dimensions
1D can be a line - something with length only, no width, no height, no thickness, no depth.
2D can be a square - a flat plane figure with only two measurements - length and width, no thickness, no depth.
3D can be a cube - a solid geometric figure with three spatial dimensions of length, width and height (or depth), occupying space and having volume.
4D can be a tesseract - with four spatial dimensions, […]
