Gravitational constant, Planck's constant, the number Fi -- a secret RELATIONSHIP. Gravitational constant = 6.673 Planck constant (quantum of action) = 6.626 6.673 * 6.626 = 44.215 Fi Number = 1.618 The moon's rotation period in days = 27.32 27.32 * 1.618 = 44.203 6.673 * 6.626 = 27.32 * 1.618 Is this a "coincidence"?! 6.673 * 6.626 : 27.32 = 1.618 Received Fi number. 6.673 * 6.626 : 1.618 = 27.32 the moon's rotation period in days is Obtained. 27.32 * 1.618 : 6.673 = 6.626 the Planck constant is Obtained. 27.32 * 1.618 : 6.626 = 6.673 the gravitational constant is Obtained.
