When was celsius discovered

He further gave a rule for the determination of the boiling point if the barometric pressure deviates from a certain standard pressure. The position of the degree zero on a temperature scale has created a lot of discussions. This reversed scale was not as awkward as we think today and it served its purpose.

The change to our modern direct scale was inevitable in the long run, however, but there is no sense in trying to give the credit to any single person.

Certainly the change of scale became obvious to the Uppsala scientists in general. No single person can be given the credit. From the scientific point of view the most important contribution to the modern temperature scale is due to Celsius because of his careful experiments on the fixed points. He is considered one of the most influential scientists of the 20th century. Charles Darwin was a British naturalist who developed a theory of evolution based on natural selection.

James C. Maxwell was a 19th-century pioneer in chemistry and physics who articulated the idea of electromagnetism. Anders Celsius was a Swedish astronomer who built the Uppsala Observatory and invented the Celsius or centigrade thermometer scale.

Following a visit to the observatory in Berlin, where he worked with Christfried Kirch, he continued to Nuremburg, where his observations of the aurora borealis first appeared in print. As Celsius importantly noted, whenever the northern lights can be seen in the night sky, significant magnetic fluctuations take place.

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. Maupertuis decided to lead an expedition that would definitively settle the dispute. He invited Celsius to join the expedition, which began in and took the group through northernmost Sweden. 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 In addition to his early observations of the aurora borealis, Celsius carried out many other astronomical studies.
