Nature vs. Maths

[Beren3000]

This is a thread for all of you out there; whether you love maths or hate them.
I've always wondered about this topic and I'll divide it into two questions:

1- Is mathematics an invention or a discovery? I mean does it actually exist in nature or is it man's own work?

2- Can perfect mathematics exist in nature? (i.e. does nature have a perfect circle or a perfect straight line, etc...)?

I'm going to post my opinions later after I hear some of you Mooters' opinions.

Speculate away!
