Lester R. Ford, a American Mathematician wrote about ford Circles in 1938 and hence it is named after him. Ford Circle is a circle whose center is at a / b, 1 / (2b^{2}) where a and b are co primes and 1 / (2b^{2}) is radius. Two Ford circles are tangent to each other and will meet at only one point.

Two ford circles do not intersect and hence their area is less than 1. Area of the Ford Circle is equal to 0.872284041.
