Anders Celsius was a Swedish scientist born in 1701 and died in 1744 . Specialist in astronomy and in physical , Celsius supervised the development of Uppsala Observatory and was part of an expedition to the region of Lapland to analyze the flattening of the earth's poles.

It should also be stressed that he was a professor at the University of Uppsala and that he also stood out for publishing, in 1733, a collection of just over 300 observations of northern lights.

An interesting curiosity about Anders Celsius is that there is a lunar crater that responds to the name of Celsius as a tribute to him.

Among the many contributions of Celsius to science , its contribution to the creation of a centigrade scale from temperatures . The Swede proposed a scale that, as the heat increased, indicated a drop in degrees. On the other hand, if the heat was reduced, the degrees increased. Years later, Jean-Pierre Christin and Carlos von Linnaeus they took the precepts of Celsius but they decided to reverse the scale.

Today is known as Celsius scale to the one whose 0 It is equivalent to 0.01 degrees below the call "Triple point" (the point where the solid state, the liquid and the gas are in equilibrium) of the Water . The caloric intensity, at this point, is equal to that of Kelvin .

It can be said that, in the Celsius scale , he 0 equivalent to melting point of frozen water (the ice). The 100 degrees Celsius , meanwhile, equal to Point of boiling of water, always at normal pressure.

It is important to keep in mind that Celsius degrees they are also called degrees Celsius . This means that 30 degrees Celsius is the same as 30 degrees Celsius .

He symbol of the Celsius degrees is ºC . Therefore, it is possible to write “30 degrees Celsius” or "30 degrees Celsius" as "30 ° C".

In addition to all of the above, we cannot overlook either that the word at hand is also used to call a literary event. We are referring to Celsius 232, which is the Festival of Terror, Fantasy and Science Fiction that is held annually in Aviles (Asturias) and which aims to publicize the most relevant novels of the aforementioned genres, both nationally as international

Presentations of books, lectures, conferences, activities in the street and even more academic proposals are those that have a place in the programming of this festival, which is open to the public and whose headquarters are the Casa de la Cultura de Avilés, located in the Plaza Domingo Acebal.

Within this literary event, it should be noted that the Kelvin 505 Awards are awarded, with which works such as "The Three Deaths of Fermín Salvochea", by Jesús Cañadas have been awarded; "The Fifth Station" by N.K. Jemisin; “The tree of lies”, by Frances Hardinge and “The second revolution” of Costa Alcalá.

In the same way, it should be noted that this festival pays a special tribute to the figure of the writer Mary Shelley, creator of “Frankestein”.
