More along the lines of multidimensional mapping: Okay! I'm
  thinking this way: EXPRESSING 2 DIMENSIONS IN 1 DIMENSION. Start
  with a line. ______ If you had to express 2 dimensions in 1
  dimension, how would you do it? You'd use two lines, and just
  remember that the 2nd line is going in a dimension you cannot
  directly manipulate. ________ ________ EXPRESSING 3 DIMENSIONS
  IN 2 DIMENSIONS. Okay - you have two dimensions. | | |
  |_________ You want to express 3 dimensions in 2 dimensions? | |
  | |_________ | | | |_________ You would just have to remember
  that the 2nd |_ is representing the 3rd dimension - going "up"
  in a direction you can't directly manipulate [but since we're in
  3 dimensions, we could simply pick up the 2nd |_ and flip it
  around into a 3 dimensional shape). But as a 2 dimensional
  being, you wouldn't be able to use the parlor trick of making a
  3D-looking box in 2 dimensions, because you can only think 3
  dimensionally in theory - perhaps even mathematically.
  EXPRESSING 4 DIMENSIONS IN 3 DIMENSIONS Okay - we're getting
  limited already, because e-mail is 2 dimensions. You have a 3D
  cube. You want to express a 4D cube. How to do it? Same way! You
  have another cube. Two cubes. But the two cubes are really 1
  cube, just stretching upwards in a direction that we cannot
  perceive. Notice what's happening here!!! Each dimension is
  STILL being expressed by a 1 dimensional thing: The ___________.
  For 2 dimensions, you have a GROUP of 2 or more __________ for 3
  dimensions you have a GROUP of 3 or more ___________ For 4
  dimensions, you have a group of 4 or more ___________ OR: You
  have two dimensions: | |___ To get three dimensions, you need
  TWO of these: | |___ | |___ always remembering that the 2nd one
  is flipped 'up', towards you. Now, same logic: You have 3
  dimensions. A cube. To get 4 dimensions, you need 2 CUBES. or 3
  2D |_'s or 4 ______ (lines). To get FIVE dimensions, you need 2
  4D cubes at minimum. *BUT* - since we are limited in expressing
  ourselves in 3 dimensions, we have other options!! 3 3D cubes
  will express 5 dimensions minimally. 4 2D |_'s will express 5
  dimensions minimally as well... 5 ______'S will also express 5
  dimensions. [to see 5 dimensions in a common computer
  application, see Microsoft Excel. You have Row: 1 [one
  dimension) You have Column A (2nd dimension) You have Worksheet
  named: REPORT_1 (3rd dimension) You have Filename named:
  NOV_REPORTS.XLS (4th dimension) You have Directory named:
  C:\REPORTS\ (5th dimension) etc. It seems to get "flat" after
  you have the 4th dimension - but it's not! NOTICE THIS! A
  DIRECTORY (5) can have a collection of Excel FILES (4). An Excel
  FILE (4) can have a collection of WORKSHEETS (3). A WORKSHEET
  (3) can have a collection of COLUMNS (2) A COLUMN (2) can have a
  collection of ROWS (1). [and one single cell, which is in a row
  that is in a column, that is in a worksheet, that is in a file,
  that is in a directory, can reference ANY OTHER cell in any
  other DIRECTORY, or FILE, or WORKSHEET, or COLUMN, or even ROW!]
  ] A box inside of boxes is a way often used to express
  multidimensionality. Even time! -- Look at Russian nesting
  dolls. They express, in one small package, 4 dimensions. It is
  the same person, at different stages in time. The Russian
  nesting doll is a 4 dimensional object. Pretty neat stuff.
  Thanks for listening - thoughts? Kenneth
