Later in his grand tour, Celsius visited scientific centers throughout Italy as well as in Paris and London. While in Paris, he became acquainted the astronomer Pierre Louis de Maupertuis. The French astronomer supported Sir Isaac newton’s theory that the shape of the Earth swelled near the equator and was somewhat flattened near the poles; at the time most of the scientific community abided by an alternative view proposed by René Descartes. Maupertuis decided to lead an expedition that would definitively settle the dispute. He invited Celsius to join the expedition, which began in 1736 and took the group through northernmost Sweden. When their measurements were compared with those of a separate group of scientists on a related expedition close to the equator, Newton’s theory was proven correct. Involvement with the project gained Celsius significant recognition and, upon his return to Uppsala, he was granted the authority and funds to establish a modern observatory there, which he completed in 1741.
