<s>[INST] What you can tell me about Anders Celsius? [/INST] I can tell you that Anders Celsius was an astronomer, physicist and mathematician from Sweden who was most well known for his proposal on measuring temperature through the Centigrade temperature scale. It was later renamed the Celsius temperature scale under his honor.

The Celsius scale, when it was initially proposed, had its measurements on backwards. This meant that 0 was the boiling temperature for Celsius, and 100 was freezing. This was reversed by Carl Linnaeus, who was friends with Anders Celsius' uncle, to be more practical.

Much of his career was spent in Astronomy, with his earliest work being new methods to calculate the distance of the sun from the earth.</s>\ <s>[INST] Your answer sounded strange, and when looking further into it maybe not correct, Anders Celsius would likly have been aware and have tried the thermometer made by the French astronomer Joseph-Nicolas Delisle with zero at the boiling point, thus creating a reversed scale with increasing numbers for decreasing temperatures, but avoiding negative numbers.
