In stark distinction, one guy, John Harrison, dared to visualize a mechanical solution--a clock that may continue percise time at sea, whatever no clock had ever been capable of do on land. Longitude is a dramatic human tale of an epic clinical quest and Harrison's forty-year obsession with construction his excellent timekeeper, recognized this day because the chronometer. packed with heroism and chicanery, it's also a desirable short historical past of astronomy, navigation, and clockmaking, and opens a brand new window on our world.

In Longitude, Dava Sobel chronicles the world's quest to tame time. In 1714, the English Parliament handed the longitude act. It validated the Board of Longitude and provided a prize of 20,000 kilos to somebody who may possibly discover a basic and useful procedure for the appropriate choice of a ship's longitude. specifically Sobel highlights John Harrison's pursuit of the prize.

Initially, for fear of ridicule, Copernicus privately circulated the paper among his friends. As the years passed, he further developed his arguments wTith diagrams and mathematical calculations. In 1533, he made a presentation of his ideas before the Pope in Rome, who is said to have given his approval. After his presentation before the Pope, Copernicus was formally requested by his friends in 1536 to publish his findings. But he continued to hesitate. It was left to his friends to go ahead and take up the responsibility of getting the work into print.

So, Copernicus decided not to publish his revolutionary theory, at least not for the time being. Between 1510 and 1514, he prepared a brief, anonymous paper to summarise his new idea. It was titled De hypothesibus motunum coelestium a se constitutis commentariolus ('A Commentary on the Theories of the Motions of Heavenly Objects from their Arrangements'). In the paper, Copernicus put forward the suggestion that the apparent daily motion of the stars, the yearly motion of the Sun, and the apparently erratic behaviour of the planets resulted from the Earth's daily rotation on its axis and yearly revolution around the Sun, which is stationary at the centre of the planetary system.

During one yuga, according to viii COSMIC VISTAS the scheme, the Sun 'passed' through all the zodiacal constellations five times, and the Moon went through all the nakshatras 67 times. 52 days, which show the remarkable astronomical and computational knowledge of the Vedic Indians. The Hindu astronomers of the Siddhantic age expressed the periods of the Sun, the Moon and the planets by the number of their periods in a mahayuga—a period of 4,320,000 years—during which the planets, the Sun and the Moon return to their original position.
