Arc Seconds Arc Minutes of Nautical Mile Mapping by Timekeeping Anciently by the Earth’s Axial Precession Rate


Did you ever wonder why there are 86,400 seconds to a day which is twice the numerical denomination (1/43,200th) of which the Great Pyramid is a reduced embodiment of a hemisphere of the earth? Time is measured accurately today by the atomic clock or mechanical devices to precisely measure solar transit time, while anciently it was by the very slow axial precession rate of the earth , 72 years/degree (of 360), so tell your friends who may be fascinated by the Great Pyramid and ancient navigation.
