The philosophy of the Yin Yang is depicted by the The “taichi symbol” (taijitu). In fact, Yin Yang is a concept of dualism, describing how seemingly opposite or contrary forces may actually be complementary,
Curiously enough, in the taichi symbol are hidden the golden ratio and its reverse. As shown in the picture.
Prove that AH = 1/φ and AC = φ
Assuming, AJ = 1, BJ = FJ = FC = BH = 1/2 and AB = AF = √5/2 (Pythagorean theorem), then:
AC = AF + FC = √5/2 + 1/2 = φ
AH = AB – BH = √5/2 – 1/2 = 1/φ
