I went to get a pizza the other night, and, since I had
six friends over, I asked that he cut it in seven pieces.
The pizzaman said he couldn't do it exactly with just
straight-edge and compass (it was a greek pizzeria), and
I asked him why.  He started talking about automorphisms
and algebraic fields and other things I don't understand -
can anybody explain this in plain english?  Is there a general
rule?
