Answer by iso for Visualizing the 4th dimension.

I view time as 4th dimension. 4th dimension would be 3D object's state in time. Time is only 1 straight line logically, but what if you let time also have vertical and horizontal axis? then that's 5th...

Answer by badjohn for Visualizing the 4th dimension.

Another way to visualize a 4D object is to imagine it passing through our 3D space. First consider a flatlander (an inhabitant of an imaginary 2D universe). If you were to push a sphere through his 2D...

Answer by Andrew D. Hwang for Visualizing the 4th dimension.

The animations below accompany an introductory talk on high-dimensional geometry.Mathematically, the second was made by putting a "light source" at a point $(0, 0, 0, h)$ (with $h > 0$) and sending...

Answer by Yves Daoust for Visualizing the 4th dimension.

The shadow of a cube is its projection on a plane. It is made of the shadows of the six faces, each giving a quadrilateral. As the face shadows overlap each other and merge, all you see is a...

Answer by Glougloubarbaki for Visualizing the 4th dimension.

From a mathematical perspective, what your professor called a shadow is a projection. Think of a surface $S$ lying in a 3D ambiant space with coordinates $(x,y,z)$. If you put a screen on the plane...
