@ 2147,27 +2147,27 @@ make one large Square, with a side of three inches, and I had hence proved to


my little Grandson that  though it was impossible for us to see the inside of


the Square  yet we might ascertain the number of square inches in a Square by


simply squaring the number of inches in the side: ``and thus,'' said I, ``we know


that threetothesecond, or nine, represents the number of square inches in a


Square whose side is three inches long.''


that $ 3^2 $, or 9, represents the number of square inches in a


Square whose side is 3 inches long.''




The little Hexagon meditated on this a while and then said to me; ``But you


have been teaching me to raise numbers to the third power: I suppose


threetothethird must mean something in Geometry; what does it mean?''


$ 3^3 $ must mean something in Geometry; what does it mean?''


``Nothing at all,'' replied I, ``not at least in Geometry; for Geometry has only


Two Dimensions.'' And then I began to shew the boy how a Point by moving


through a length of three inches makes a Line of three inches, which may be


represented by three; and how a Line of three inches, moving parallel to


represented by 3; and how a Line of three inches, moving parallel to


itself through a length of three inches, makes a Square of three inches every


way, which may be represented by threetothesecond.


way, which may be represented by $ 3^2 $.




Upon this, my Grandson, again returning to his former suggestion, took me up


rather suddenly and exclaimed, ``Well, then, if a Point by moving three inches,


makes a Line of three inches represented by three; and if a straight Line of


makes a Line of three inches represented by 3; and if a straight Line of


three inches, moving parallel to itself, makes a Square of three inches every


way, represented by threetothesecond; it must be that a Square of three


way, represented by $ 3^2 $; it must be that a Square of three


inches every way, moving somehow parallel to itself (but I don't see how) must


make Something else (but I don't see what) of three inches every way  and


this must be represented by threetothethird.''


this must be represented by $ 3^3 $.''




``Go to bed,'' said I, a little ruffled by this interruption: ``if you would talk


less nonsense, you would remember more sense.''
