Hi,
	In "Number Theory" Hardy presents a result which shows that the
closest rational approximation to an irrational number is:

	| r - p/q | <= 1/q^2,	r - irrational, 0<p<=q, p, q rational

which is the same thing as saying the closest point of an approximating
lattice to a line is O(1/q^2).  I was wondering if anyone could direct
me to any results concerning circles or any curves with curvature.
Thanks in advance.
