The French Geodesic Mission to the Equator (French: Expédition géodésique française en Équateur), also called the French Geodesic Mission to Peru and the Spanish-French Geodesic Mission, was an 18th-century expedition to what is now Ecuador carried out for the purpose of performing an arc measurement, measuring the length of a degree of latitude near the Equator, by which the Earth's ...
The final results of French Geodesic Mission, published by La Condamine in 1745, combined with the measurements of meridian arc near the Arctic Circle that had been published in 1738 by Pierre Louis Maupertuis following the French Geodesic Mission to Lapland, decisively vindicated the predictions first made by Isaac Newton in Book III of his ...
The placement of the equatorial line was defined throughout a 1736 expedition called the French Geodesic Mission.While such studies would later determine the exact measure and shape of the world, astronomers involved missed the possibility of encountering the remnants of highly sophisticated geographical achievements made on “Equatorial” territory for hundreds of years before their arrival.
Charles Marie de La Condamine (French: [la kɔ̃damin]; 28 January 1701 – 4 February 1774) was a French explorer, geographer, and mathematician.He spent ten years in territory which is now Ecuador, measuring the length of a degree of latitude at the equator and preparing the first map of the Amazon region based on astro-geodetic observations.
The distance from the North Pole to the Equator was then extrapolated from the measurement of the Paris meridian arc between Dunkirk and Barcelona and the length of the metre was established, in relation to the Toise de l'Académie also called toise of Peru, which had been constructed in 1735 for the French Geodesic Mission to Peru, as well as ...
In Philosophiæ Naturalis Principia Mathematica (1686), Isaac Newton gave a theoretical explanation for the "bulging equator", [Note 5] which also explained the differences found in the lengths of the "second pendulums", [13] theories that were confirmed by the French Geodesic Mission to Peru undertaken by the French Academy of Sciences in 1735 ...
December 3 – Ecuadorian scientist Pedro Vicente Maldonado departs from Brazil in order to purchase the most state-of-the-art equipment for the French Geodesic Mission [67] December 9 – At Haarlem, Dutch astronomer Dirk Klinkenberg becomes the first to observe the Great Comet of 1744.
Pedro Vicente Maldonado y Flores (November 24, 1704 in Riobamba, Royal Audience of Quito (today's Ecuador) – November 7, 1748 in London, England) was an Ecuadorian scientist who collaborated with the members of the French Geodesic Mission. As well as a physicist and a mathematician, Maldonado was an astronomer, topographer, and geographer.
