The Great Navigators of the Eighteenth Century By Jules VerneCasting a visionary eye over the 18th century, Jules Verne traces navigation to the first astronomers and cartographers in this monumental history of early expeditions. Assessing the influence of Captain Cook and his predecessors in the first part of the book, he then introduces the reader to the remarkable efforts of French navigators across the globe in a gripping narrative.Before we enter upon a recital of the great expeditions of the eighteenth century, we shall do well to chronicle the immense progress made during that period by the sciences. They rectified a crowd of prejudices and established a solid basis for the labours of astronomers and geographers. If we refer them solely to the matter before us, they radically modified cartography, and ensured for navigation a security hitherto unknown. Although Galileo had observed the eclipses of Jupiter's satellites as early as 1610, his important discovery had been rendered useless by the indifference of Governments, the inadequacy of instruments, and the mistakes committed by his followers. In 1660 Jean Dominique Cassini published his "Tables of the Satellites of Jupiter," which induced Colbert to send for him the following year, and which obtained for him the superintendence of the Paris Observatory. In the month of July, 1671, Philippe de la Hire went to Uraniborg in the Island of Huen, to take observations for the situation of Tycho Brahe's Observatory. In that spot he calculated with the assistance of Cassini's Tables, and with an exactitude never before obtained, the difference between the longitudes of Paris and Uraniborg. The Academy of Sciences sent the astronomer Jean Richter the same year to Cayenne, to study the parallaxes of the sun and moon, and to determine the distance of Mars and Venus from the earth. This voyage, which was entirely successful, was attended with unforeseen consequences, and resulted in inquiries shortly after entered into as to the shape of the earth. Richter noticed that the pendulum lost two minutes, twenty-eight seconds at Cayenne, which proved that the momentum was less at this place than at Paris. From this fact, Newton and Huyghens deduced the flatness of the Globe at the Poles.
Autorenporträt
Jules Verne (1828-1905) was a French novelist, playwright, and poet who is best known for his enduring tales of adventure and discovery that include Journey to the Center of the Earth, Twenty Thousand Leagues under the Sea, and Around the World in Eighty Days. Verne's books about a variety of innovations and technological advancements-including the submarine, space travel, terrestrial flight and deep-sea exploration-years before they were practical realities, laid much of the foundation of modern science fiction. One of the most prolific, famous French novelists of all time, Verne has been the second most-translated author in the world since 1979, ranking between Agatha Christie and William Shakespeare.
