I thought this was pretty interesting. I never imagined approaching it from all those different angles (and I envy anyone who can decipher all that higher-math cryptology), and it's always fun watching logicians try to struggle with an absurdity.http://en.wikipedia.org/wiki/Divide_by_zero
The article should just say.
Don't try. You can't do it.
All that mathematical formula proving you can't do it is TOTALLY moot.
I like how in the irony section it mentions when Hinkly shot Regan, all his bullets missed, but one hit the bullet proof windscreen on his car and bounced back into him.
So the glass designed to stop him being shot was the reason he got shot.
what's even more ironic is that the object of Hinckley's obsessive sexual fantasies.... turned out to be a lesbian!
