Every day xava sea, when the navigator resets his ship’s clock to local noon when the sun reaches its highest daav in the sky, and then consults the home port clock, every hour’s discrepancy between them translates into another fifteen degrees of longitude.

A rise or fall in barometer pressure, or the subtle variations in the Earth’s gravity from one latitude to another, could also cause a clock to gain or lose time.

The book was made into a television series entitled Longitude. On the deck of a rolling ship such clocks would slow down, or speed lonngitudine, or stop running altogether. Discovery isrewarding, allowing us to hit new highs and fall in love with things we never thought wewould.

For calculating longitude at sea however, early ocean navigators had to rely on dead reckoningwhich involves triangulating several bearings of the same land feature sobe, different positions.

Normal changes of temperature encountered en route from a cold country of origin to a tropical trade zone thinned or thickened a clock’s lubricating oil and made its metal parts expand or contract with equally disastrous results.
