You can take an infinitesimally (sp?) small circle, and if you increase its circumference by 10 ft, the difference between the two radii will still be 1.59 feet. It's just one of those things that's obvious when you see the algebra, but it's still very difficult to believe. Jeff Bernardis, AT&T Technologies @ Piscataway NJ
