401 - 299 grown here
[edit]In accordance with a sensible procedure practiced by User:GUllman, the articles for the numbers 401 to 499 will be 'grown' here in the article on 400 until they are big enough to merit their own articles. Once that happens, a new page is created for the number in question, linking back to this page, and this page is changed to indicate that the number now has its own article. User:PrimeFan
400th anniversary
[edit]How do you name a 400th anniversary, quadricentennial or quatercentenary?? "Centennial" and "Bicentennial" have the same suffix, so using extrapolation, "quadricentennial" should make more sense?? Any opinions?? 66.245.124.50 01:56, 7 Nov 2004 (UTC)
- Quadricentennial sounds more correct to me. PrimeFan 18:08, 15 October 2005 (UTC)
Eventually yields 495
[edit]I tried the 495 digit thing with a number I randomly typed, 194. Got to 495 after about seven steps. Haven't checked for any other three-digit integers. PrimeFan 18:08, 15 October 2005 (UTC)
- I noticed that this does not work with the number 100. --דניאל - Dantheman531 23:59, 6 September 2006 (UTC)
- It does work with 100, if you consider the leading zeros in each step. 2001:638:1558:8C70:FC79:E957:4D4D:4CFE (talk) 14:24, 12 December 2024 (UTC)
Introduction
[edit]Currently, the introduction reads thus: 400 (four hundred) is the natural number following three hundred [and] ninety-nine and preceding four hundred [and] one. Why does the introduction say "three hundred [and] ninety-nine" as well as "four hundred [and] one"? The word and is not used in numbers unless expressing fractions. --דניאל - Dantheman531 00:01, 7 September 2006 (UTC)
In reply to the above, I at least am pretty sure that "four hundred and one" is in common English usage (both British and American). To say it's "not used" is simply not true. 62.244.190.66 (talk) 12:02, 23 January 2008 (UTC)
- It's common language, but it's improper. — Preceding unsigned comment added by PixelScientist (talk • contribs) 16:48, 4 September 2011 (UTC)
- In standard British English it is always used: "Four hundred one" sounds very odd. The classic game of darts ends with the cry of "One hundred and eighty" when the final score is reached. Always. 85.211.13.188 (talk) 12:07, 19 October 2011 (UTC)
425
[edit]Is there any greater meaning to the number 425? I've seen hats with the number on them. --Brandon Dilbeck 23:16, 27 February 2007 (UTC)
427
[edit]The sum of the factors of 427 (1, 7, 61, and 427) equals 496, which is a perfect number, but there are 4 factors, which is not a perfect number, so 427 is not a sublime number. —Preceding unsigned comment added by 208.73.31.50 (talk) 20:23, 26 July 2008 (UTC)

Verdian Ay (432 Hz)
[edit]"432" is the number of the frequency of the Verdian Ay (432 Hz). It is a relevant number of the tunings of many musical instruments. Many recorded musics use these Verdis.

- Providing a source for this claim would be a good idea. Dhrm77 (talk) 00:29, 22 January 2025 (UTC)
- @Dhrm77:: The article "Scientific pitch" contains an information over the Verdi (432 Hz).
- Thank you!

I do not think this belongs in the number article. Too many errors/confusion/silliness. But what is "Verdian Ay"? I mean, what is "Ay"? Imaginatorium (talk) 15:59, 23 January 2025 (UTC)
- @Imaginatorium:: "Ay" is the name of the letter "A" like this "bee" ("B"), "cee" ("C"), "dee" ("D"), "e" ("E"), "ef" ("F") and "gee" ("G").
