I was thinking about the 90° angle between the x, y, and z-axis.
It is all so perfect. So I said you need two independent real
numbers (cooridinates) to describe a point in a plane. Then I
thought about putting the x and y axis at a 10° angle instead of
90°, and noticed you could still get to all the points on the
plane. Next I attempted to find a way to describe all the points
on a plane with only 1 number. Is it possible? So at first I
played around with the idea of a spiral that was so close
together at each pass around that it would take infinite times
to make up some area, but this idea soon I decided was dumb and
incomprehensible. Then I came up with a plausible idea, if you
don't mind a jumbled mess in place of two nice x and y axis. So
this is only a first try at this and I hope to come up with
refined examples that use negative numbers as well as decimals
later, but for now I am only using whole numbers. I started at
(-1,1) and called this 1. Then (0,1) would be 2. Here is a
chart. (x,y) 1-D number A
