Andres celsius why is he famous

When Erik Burman died in , Celsius took over his lectures in astronomy in addition to substituting for the professor of mathematics. This experience allowed him to be appointed Professor of Astronomy in Uppsala in He had been an assistant secretary of the Royal Society of Sciences in Uppsala since and, following the death of Burman he took on the role of secretary. The University of Uppsala was now a very strong centre for mathematics and astronomy with Klingenstierna and Celsius both world-class scholars.

In , following in his grandfather's footsteps, Celsius decided to travel through Europe and he received permission on 23 May of that year. He did not travel alone for he had as a travelling companion Jonas Meldercreutz - , a young mathematician who would be appointed to the chair of mathematics at Uppsala after Klingenstierna retired in One of the tasks Celsius and Meldercreutz undertook was to visit learned societies and academies, aiming to set up links with the Royal Society of Sciences in Uppsala.

During his trips, Celsius made several astronomical observations with a quadrant he bought in Berlin. In , he published of his observations on the northern lights while in Nuremberg. It included information about future astronomical phenomena worthy of observation, along with news and reviews. After initial complaints that the news was too old due to the slow posting of the time , Celsius started admitting observations from the readers, but the magazine stopped publication two years later after probably 45 issues.

In late he travelled to Bologna, where he assisted Eustachio Manfredi with his observations. After Bologna he travelled to Rome where again he made observations. Celsius loved Italy and wrote to his mother, saying that he wished he could swap Uppsala for an Italian city so that he would never have to leave. When Celsius arrived at Paris in late , the scientific community was in the middle of a discussion about the shape of the Earth. Unlike his grandfather, Celsius supported Pierre de Maupertuis , who defended Newton 's theoretical argument of an oblate Earth.

The Academy asked Celsius to make the corresponding observations in Sweden but he had to turn down their request since he had neither the financial support nor the necessary instruments. Celsius, therefore, joined the Arctic Circle expedition, headed by Maupertuis , and it was probably on his suggestion that it was decided to go to Lapland.

His grandfather had led an expedition with a similar goal in , but without success. Celsius was sent on a short trip to London to commission a zenith sector from Graham, a revered instrument maker of the time.

The expedition departed from Dunkirk, France, in April They arrived at Tornea in the summer of There, they measured a network of triangles along the river Torne oriented north to south.

During winter, the difference was established using the zenith sector at the northern and southern ends of the network. The expedition returned to Paris in the summer of The results confirmed that Newton was in the right. Celsius took part in the debate which followed, where Jacques Cassini and his followers put into question the accuracy of the observations made during the expedition.

In it, Celsius shows that, in his previous measures of the meridian in France, Cassini had committed bigger mistakes than the ones he was accusing them of having made. This was confirmed by a later measurement of the French meridian and the results of the Peru expedition confirmed the findings of the Lapland expedition. Due to the success of the Lapland expedition, Celsius received a pension of livres per year from the French government.

Celsius originally called his scale centigrade from the Latin for "hundred steps". For years it was simply referred to as the Swedish thermometer. In most of the world adopted the hundred-point scale, calling it the Celsius scale.

On April 25, , at the age of forty-two, Anders Celsius died of tuberculosis, a terrible disease that attacks the lungs, bones, and other body parts.

He left behind many dissertations long writings on astronomy, as well as a well-received book entitled, "Arithmetics for the Swedish Youth," published in But for all of his accomplishments in his life's work of astronomy, the name Celsius is forever tied to an instrument used every day throughout most of the world.

The Celsius scale The work for which Celsius is best known is his creation of a hundred-point scale for temperature; although he was not Anders Celsius. World of Invention, 2nd ed. User Contributions: 1. A thermometer is a device that measures the temperature of things.

The name is made up of two smaller words: Thermo means heat and meter means to measure. You can use a thermometer to tell the temperature outside or inside your house, inside your oven, even the temperature of your body if you're sick. The Celsius scale is named after Anders Celsius.

The Celsius scale is sometimes called centigrade scale. The results from this trip made a large impact, and brought Celsius to fame.

The Celsius observatory at Uppsala University was completed in In that period of time, much of the meteorological and geographical data was considered to be part of astronomy, so Celsius also engaged in those areas of research in his astronomy career. He used colored plates of glass to measure the magnitude, or brightness, or the stars he identified.

He believed at the time that the ocean water was evaporating. Most notably, Celsius developed the first Celsius thermometer in order to take meterological measurements. Originally, this temperature scale used 0 for the point at which water boils , and for the point at which water freezes. Later, the scale was reversed into the current metric.
