To calculate your position using time, the position of celestial bodies, and mathematical tables. Position is determined by measuring the apparent altitude of one of these objects above the horizon using a sextant and recording the times of these sighting ...

An imaginary sphere surrounding the globe that contains the sun, moon, stars and planets.

Electrochemical system consisting of an anode and a cathode immersed in an electrolyte. The anode and cathode may be separate metals or dissimilar areas on the same metal. The cell includes the external circuit, which permits the flow of electrons from th ...

A component of a electrochemical battery. A 'primary' cell consists of two dissimilar elements, known as 'electrodes,' immersed in a liquid or paste known as the 'electrolyte.' A direct current of 1-1.5 volts will be produced by this cell. A 'secondary' c ...
