27th November Anders Celsius's birthday
Anders Celsius was an astronomer who invented the Celsius temperature scale, the most widely used in the world today. Celsius was primarily an astronomer and did not even start working on his temperature scale until shortly before his death.
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. What set Celsius's scale apart from all of the others was his decision to assign the freezing and boiling points of water as the constant temperatures at either end of the scale.
When Celsius introduced his scale in 1737, 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. A year later the two constants were switched, creating the temperature scale used today. Celsius originally called his scale centigrade (from the Latin for "hundred steps"). For years it was simply referred to as the Swedish thermometer. In 1948 most of the world adopted the hundred-point scale, calling it the Celsius scale.

My god
ReplyDeleteZero being boiling and negative one hundred being freezing would have been funnier.
ReplyDeleteGood morning Corina Marinescu
ReplyDeleteHola Guillermo Abreu
ReplyDeleteBuenos dias Corina
ReplyDeleteVery good information.
ReplyDeleteThanks again for something cool and useful!
ReplyDeleteIntetesting I wonder why Celsius wanted the scale in the reverse to what it is now didn't know centigrade was Latin ty .you'd make a great teacher Corina your son is one lucky fella
ReplyDeleteBoiling water was easy in the 18th century, people made a fire and voila. Cooling water on the other hand....
ReplyDeletePlus, if you think about it, Carlo, freezing water remains at 0 Celsius until all of it is frozen. Then it starts getting colder. Boiling water remains at 100 Celsius until all of it has turned to steam, then it gets hotter if more heat is added. So, made sense for them to use 0 for boiling as a start point on the scale.
Oh, and danke for the nice words :)
Corina Marinescu Yes of course ty good point about the time when it was formulated Corina freezing water only happened in nature unlike now its a common thing
ReplyDeleteWas easier to use boiling as a start point...all start points...start with 0 :)
ReplyDeleteCorina Marinescu thanks you tickled my thalamus ;)
ReplyDelete11月27曰是攝氏溫度計発明人Celsius 的生日。
ReplyDeleteStill can't figure out why we don't use a scientific form of measurement in this country, while the rest of the world uses metric.
ReplyDeleteDontrae
ReplyDeleteMichelle
ReplyDeleteTwo things I wish would change in the USA:
ReplyDelete1 - Use the metric system
2 - Abolish Daylight Saving Time
How did he present the scale in 1747? According to the date of death, he died in 1744, Anders had been dead for 3 yrs already upon presenting his scale!
ReplyDeleteMary Agnes that's a good observation. Thanks for the error report. The papers were published in 1737.
ReplyDeleteJared Ribic Yeah, I am from middle of Europe and I feel sad whenever I need something in inches (as some devices I use are made in the US). And imagine the savings if you wouldn't need all the reduction pieces. And of course, I totally agree about DST (we have it too). Ah well, man can dream...
ReplyDeleteJan Remsa - and they wouldn't have crashed the Mars Lander, had it not been for an error in converting from one system of measurement to another.
ReplyDeleteJust make IT FIT, IF IT', ISN'T BROKE DON'T FIX IT, JUST IMPROVE IT!
ReplyDeleteThank you Corina Marinescu. I did however find this interesting to read about. Facts I never knew!
