Celestial Navigation is the art and science of finding your way by the sun‚ moon‚ stars‚ and planets‚ and‚ in one form or another‚ is one of the oldest practices in human history. Celestial navigation‚ also known as astronavigation‚ is a position fixing technique that has evolved over several thousand years to help sailors cross oceans without having to rely on estimated calculations‚ or dead reckoning‚ to know their position. Celestial navigation uses "sights‚" or angular measurements taken between

which the time in which a pendulum swings back and forth‚ does not depend on the arc of the swing‚ the isochronism. Eventually‚ this discovery would lead to Galileo’s further study of time intervals and the development of his idea for a pendulum clock.
