The star Sirius, the brightest star in the sky, needed 25 of his plates to be extinguished. Fahrenheit came up with the idea that Mercury boils around 300 degrees on this temperature scale. Using his photometric system, Celsius made observations of around 300 eclipses and other astronomical objects, which was thoroughly cataloged and published. His grave is next to his grandfather's, Magnus Celsius, in the church at , about 5 km north of central Uppsala. 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 the first to have done so, as several hundred-point scales existed at that time. Celsius also endeavoured to create a star catalogue and for this he wrote Constellatione Tauri , 1743, and Constellatione Leonis , 1741, among other works.
Important Events of the 18th century and during the life of Anders Celsius include: Jethro Tull inventing the seed drill, the piano is invented by Bartolomeo Cristofori and the first mercury thermometer was invented by Gabriel Fahrenheit. This was assigned as 32 °F. For a long time Celsius hesitated unsure whether to set up the classical instrument for this work at the observatory or at his home in Sävja. While many today associate his name with the development of the Celsius temperature scale, he did not actually create the scale we know today. Anders Celsius What's the temperature outside right now? Except, he studied other things, such as math and physics.
Swedish scientist Anders Celsius addressed this issue in a rather simple way and forever changed the way we talk about temperature. Global Warming What will surprise many is the fact that Celsius had drawn the conclusion from his observations that the world was actually beginning to warm up, little by little. However, the scale he created was not as we know it today. He could then compare the magnitudes of the stars by the number of glass plates needed to extinguishe the light. Fahrenheit died in The Hague and was buried there at the Cloister Church.
When Celsius introduced his scale in 1747, it was the reverse of today's scale, with the boiling point of water being zero degrees and the freezing point being one hundred degrees. For decades mercury thermometers were a mainstay in many testing laboratories. On 21 May 1728 he was examined on his thesis Dissertatio gradualis de existentia mentis by Johan Hermansson, the professor of law, philology and politics. Later on, a reversed form of his original design was adopted as the standard and used in almost all the scientific works. He supported the formation of the in in 1739 by Linnaeus and five others, and was elected a member at the first meeting of this academy. Because of this, Spole was well informed of the scientific state of Europe. He spent several years studying the aurora borealis in an attempt to identify the phenomenon's origin.
In 1948 most of the world adopted the hundred-point scale, calling it the Celsius scale. Celsius was sent on a short trip to London to commission a zenith sector from Graham, a revered instrument maker of the time. Celsius actually determined it best to start the scale at 100 indicating the freezing point of water to zero for water's boiling point. His father was a Swedish astronomy professor Nils Celsius, and his grandfathers were mathematician Magnus Celsius and astronomer Anders Spole. In his paper, Observations of two persistent degrees on a thermometer, Celsius describes experiments conducted to show the freezing point of water is independent of one's position on Earth and atmospheric pressure. He also assessed the brightness of stars with measuring tools.
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. Like father like son they say, so Celsius decided to study astronomy too. He studied at the University of Uppsala, where his father taught, and in 1730 he, too, was awarded a professorship there. Celsius, therefore, joined the Arctic Circle expedition, headed by , and it was probably on his suggestion that it was decided to go to Lapland. He began a series of observations using colored glass plates to record the magnitude size of certain stars.
The idea of his system consists of using identical transparent glass plates and viewing the ray of light from a star through them. Anders was also the grandson of respected Swedish astronomers Magnus Celsius and Anders Spole. He was born on 27 November 1701 and passed away on 25 April 1744. Upon his return he was appointed steward manager to Uppsala's new observatory, a building designated for studying the universe. Celsius traveled frequently in the early 1730s, including to Germany, Italy and France, when he visited most of the major European observatories. He is buried next to his grandfather Magnus Celsius in the church of Gamla Uppsala.
However, Fahrenheit's interest in natural science led him to begin studies and experimentation in that field. One of his best-known work is the definition of the international temperature scale. Biography of Anders Celsius: 1701 - Born on November 27th in Uppsala, Sweden. The Swedish Scientist Who Changed Our Notion of Temperature Before Fahrenheit, Kelvin, and Celsius, there were no standard scales for measuring temperature.

You'd think that once someone becomes professor they must know it all. For his metereological observations he constructed his world famous , with 0 for the boiling point of water and 100 for the freezing point.
