Re: 2D, 3D and 4D Man
Don't we live in a 4D world with the 4th dimension being time? We need 4 co-ordinates to describe the position of something (its traditional x,y,z co-ordinates and a fourth co-ordinate to say what time it occupied that state).
Sorry to be nittish but I've only started reading in this forum and have noticed the 3D world reference a lot and wanted to clarify.
