Talk:1900

message: I changed the infobox so that the correct century (the 19th) is shown in bold. The 20th century starts with 1901, not 1900. --Thorsen 07:15, 13 January 2006 (UTC)

message: Did anyone notice that Hawaii becomes a U.S. Territory twice (on both February 22 and then again on July 14th)?  Very impressive.  —Preceding unsigned comment added by 69.225.120.250 (talk) 10:47, 7 September 2007 (UTC)
replies: text: It didn't even happen in 1900 according to the Territory of Hawaii article. The first territorial governor took office in 1900 though - his article, Sanford B. Dole doesn't give any dates. I have therefore removed both mentions of Hawaii becoming a territory in this article. Graham87 14:05, 7 September 2007 (UTC)

message: If Rowland really discovered how the magnetic field works then why doesn't it mention it in either the articles on Rowland or on the Earth's magnetic field? Or is someone making stuff up? Gmackematix (talk) 23:33, 24 September 2009 (UTC)

message: Slightly strange point any possibly being noted in the wrong place, but Microsoft Excel thinks 1900 Jan 1st was a Sunday and there there was a 29 Feb in it. Excel seems to know that 2100 is not a leap year. Odd point I know but something i found curious.--80.229.182.42 (talk) 16:21, 4 July 2008 (UTC)

message: According to the rules I know, it is not.  But the article once says it is, and then later says it isn't!  — Preceding unsigned comment added by AegNuddel (talk • contribs) 20:05, 19 November 2015 (UTC)

message: Okay, I can't seem to edit it because it's in a template that I can't figure out, but the following sentence should be removed from the lead: "Note that the Julian day for 1900 is 12 calendar days difference, which continued to be used from 1582 until the complete conversion of the Gregorian calendar was entirely done in 1929." Aside from being covered later in the paragraph, it does not specify a location for which the conversion was completed in 1929. --Khajidha (talk) 10:33, 24 November 2015 (UTC)

message: I noticed that there was a box for the founding of Australia, but no mention of this event on the list of historical facts.  I looked to see if there had ever been an item for Australia's founding, and found that established Wikipedia editor DerbyCountyinNZ had, in good faith, presumably, removed many items between 28 March 2014 and 18 April 2014, with the justification that they were either non-notable or ought to be covered in the country's Wikipedia page for that year.  While it may be that this user was correct in many instances, I felt that several of the items, such as the founding date of Australia, were, in fact, notable enough to be included on the 1900 page.  It's also difficult for one person to be the sole judge of notability to that degree.  As such, I felt it would be best to restore these items, in most cases, as they existed on 28 March 2014.  Let the reader decide on whether such items are of sufficient notability.  This concerns about 54 items on the page.  I also looked at 1901 and noted that this editor had not removed items from that page, so this appears to not have been a systematized change.  As there may be differences of opinion on this matter, I left a note on my edit referring to this explanation on the talk page to initiate discussion before further changes along these lines.Ryan Reeder (talk) 16:50, 2 April 2019 (UTC)

message: This article should included a mention of Max Planck's introduction of the idea of light quanta in the headline-introduction area. 1900 is the year that the idea of quantization is introduced into physics, and leads in 1905 to Einstein's explanation of the photoelectric effect, his Nobel Prize in Physics, and the beginning of the Quantum Revolution.
