Hi Mutt,
The 4th dimension is sometimes considered to be time. So for example, let's say you want to meet a friend on a street corner. You might specify a location of a building which is on the corner of Street X (1) + the corner of Street Y (2) + the floor of the building Z (3), and then finally the date and time of the meeting (T). X+Y+Z+T = the location of the meeting.
However, more modern theory combines space and time into a single unit, called Spacetime. There is a really go primer on the subject at this URL :
