Talk:Anders Celsius

Birthplace
Somebody changed birthplace from Uppsala to Ovanåker, but according to the article in Svenskt biografiskt lexikon, he was born in Uppsala. There is a school in Uppsala thats named after him. What source exists for giving Ovanåker as the birthplace? up+land 20:07, 26 Jun 2005 (UTC)

was he born on novemberOf Swedish, Julian, or Gregorian calendar?--Jusjih 10:53, 19 October 2006 (UTC)

Scale
didnt his scale have 0 for boiling and 100 for freezing?


 * Yes, that's right. / Fred-Chess 14:01, 29 January 2007 (UTC)


 * The text does not reflect that Celsius had the scale with 0 C as boiling water and melting ice at 100C.! —Preceding unsigned comment added by 82.146.196.20 (talk) 13:38, 14 November 2007 (UTC)

Quite correct. Mark.Chivers (talk) 19:52, 17 July 2022 (UTC)

Birthdate
A lot of other links state that Anders Celsius was born January 27th 1701, e.g. http://www.surveyor.in-berlin.de/himmel/Bios/Celsius-e.html, not November 27th 1701 - so which birth date is the correct one?


 * Anders Celsius was born on the 27th of November in 1701. It is stated so in the Nordisk familjebok, Sweden's most comprehensive encyclopedia of all times. The link - http://runeberg.org/sbh/celsiand.html Twangdrinking (talk) 21:09, 7 January 2008 (UTC)
 * We should assume that this document used the then-Swedish calendar? (see Swedish calendar) Cowbert (talk) 05:38, 8 January 2008 (UTC)
 * That's probably a fair assumption, but I don't think we can rely on it in order to arrive at the Gregorian date for the purposes of Wikipedia. --  JackofOz (talk) 07:34, 9 July 2008 (UTC)

Carl Linnaeus
Carl Linnaeus's name is spelled in three different ways in the article. I'm going to unify them. --Jay (Histrion) (talk • contribs) 15:12, 14 October 2010 (UTC)

Nonsense
Was the scale invented one year after Celsius' death? "Inverted" would be more proper ;-) PS. The page is protected.

Death?
Curious to know more about this person. I guess there isn't much to be had, but I find it fascinating that he accomplished so much, died young, but there is no information on how or where he died or why he was so young when he died. For someone of such renown, I am surprised there isn't more...? Jdevola (talk) 16:23, 2 May 2018 (UTC)

Change "His thermometer was calibrated with a value of 100° for the freezing point of water and 0° for the boiling point." to "His thermometer was calibrated with a value of 0° for the freezing point of water and 100° for the boiling point. MooseManJoe (talk) 05:41, 2 June 2019 (UTC)

Scale reversal
Anders's original scale had the boiling point at 0 and the melting point at 100. This article says: "In 1745, a year after Celsius's death, the scale was reversed by Carl Linnaeus to facilitate more practical measurement."

But I think that was already done by Jean-Pierre Christin in 1743. Linnaeus might've had the same idea a year or two later. But I'm not sure that's worth noting at all. Maybe the idea didn't catch on until he proposed it. (I'm not sure.) But even if we do note Linnaeus's idea, we should note Christin's idea too.

In section 2 Careers, paragraph 5, line 6, the following error was noted " His thermometer was calibrated with a value of 100° for the freezing point of water and 0° for the boiling point.

The Line should read as follows. In paragraph 5, line 6, "His thermometer was calibrated with a value of 100° for the boiling point of water and 0° for the freezing point. Armymp1991 (talk) 23:34, 18 February 2020 (UTC)

Change: His thermometer was calibrated with a value of 100° for the boiling point of water and 0° for the freezing point.

To: His thermometer was calibrated with a value of 0° for the boiling point of water and 100° for the freezing point.

Slight Misspelling
In the first sentence, second paragraph under the section Early Life and Education, change: "...nephew of botanyst Olof Celsius..." To: "...nephew of botanist Olof Celsius..." Bolded for clarity. 65.99.107.19 (talk) 01:40, 20 September 2021 (UTC)

Celsius / Centigrade scales
No-one, or rather no official body has renamed the Centigrade scale as Celsius as far as I can tell. Please quote your source if you are going to claim this. The two scales just got mixed up as both used the freezing point and the boiling point of water, and a range of 100. Mark.Chivers (talk) 18:37, 17 July 2022 (UTC)

Freezing point
The description of Celsius scala is completely the opposite - 0 is freezing point and 100 is water boiling. 2A02:1210:5ABF:6900:5DC4:22DA:E2E1:E16 (talk) 21:54, 2 June 2024 (UTC)
