The first 10 digits of the golden ratio φ can be rearranged to give the first 10 digits of 1/π: φ = 1.618033988 … 1/π = .3183098861 … And the first nine digits of 1/φ can be rearranged to give the first 9 digits of 1/π: 1/φ = .618033988 … 1/π = .318309886 … In 1983 amateur mathematician George Odom discovered that if points A and B are the midpoints of sides EF and DE of an equilateral triangle, and line AB meets the circumscribing circle at C, then AB/BC = AC/AB = φ. Odom used this fact to construct...
