Properties of circles

[Chris Corrigan]

Thanks Joelle...those are indeed the instructions.

Try this exercise Therese:  Make a picture in your mind that you are
facing east and sitting on a line that runs exactly north-south...a
straight line.  Imagine trying to see that whole line at once.  You
can't do it.  You have to turn your head right and left to see it.

Now imagine that line curving in to the north or south of you so that it
makes a giant arc or a circle in front of you.  You can see the whole
line now, where it curves around towards you and meets beneath you and
where it extends away from you.  And you might describe that whole line
as being in front of you.  There is no part of that line that is behind
you.  Therefore, you are sitting "behind" every other point on the line.


Even better, get 8 or 10 people (or more) and just try following the
directions with them!  But if you lack a handy crowd at the moment, this
thought experiment should do.

Cheers,

Chris
