[edit] Numeric value
Who assigned a 'numeric value' of 800 to omega? And on what grounds? That's more interesting than the number itself. Otherwise it belongs in the as legend has it file!User:Wetman
This refers to the ancient Greek numeration system, in which α had the value 1, β was 2, λ was 20, and so on. The word 'numeric' in 'numeric value' is linked to the article on Greek numerals, which explains this. -- Dominus
[edit] Big O notation
Please help: I am confused as to what the statement "literally, big O" means here. Omicron is listed as the symbol used to describe "Big O notation". What is the "big O" mentioned here literally translated from, and if Omega is literally big O, why isn't it used as the symbol for "Big O notation" instead of Omicron?
- There are two Greek letters that transliterate into the English letter O. One of them is omicron, and the other is omega. The Greek word omega means, literally, big O; you can see mega (big) in there (think megaphone or megalopolis or megabyte or any other word that contains mega). The Greek word omicron means little O; you can see micro (little) in there (think microscope or microbrew or Micro Machines).
- "Big O notation" wasn't invented until much later. The name "big O" in this case refers to the omicron which is used, which looks like a capital letter O. So "big O" here means "capital O", even though technically it's an omicron, not an O.
- Hope this makes things clearer. —Bkell 23:15, 11 Apr 2004 (UTC)
[edit] The symbol for Omega
How was the the symbol for Omega formed? I once heard that the capital letter was formed as an O with an underbar, and that the lower case letter consisted simply of two o's, but I don't know whether this is correct.
[edit] ω the ordinal
Why was omega listed in both the upper and lower case "symbol" sections? It was listed in one as the first transfinite ordinal, and in the other as the first uncountable ordinal. Aren't these one and the same symbol, which is written in lower case? Jamie 03:47, 13 November 2005 (UTC)
- The first transfinite ordinal (the union of all finite ordinals) is not the same as the first uncountable ordinal (the union of all countable ordinals). I'm not familiar with the use of upper case Ω for the latter (the usual designation is ω1). Hylas 21:11, 1 December 2005 (UTC)

[edit] Upper case omega in reality
Just thought I'd add this and leave it up to regular editors to decide whether or not it's worth inclusion: Many species of catfish - specifically plecostomus species and others in the same family (Loricariidae) have an eye (iris) structure that is refered to as 'Omega eye' simply because of its remarkable similarity to the upper case symbol for omega. See http://www.wetwebmedia.com/FWSubWebIndex/loricariids.htm and Plecostomus and here an image http://www.malawicichlidhomepage.com/other/Friedel149.jpg. The omega is of course upside down.HappyVR 18:36, 18 May 2006 (UTC)
[edit] OMEGA FOR DUMMIES
Omega is the last letter of the greek alphabet
[edit] Lengthy lists to text nonsense
I totally disagree with the tag somebody has slapped on this article. The lists should remain as they are. Gene Nygaard 12:46, 11 October 2006 (UTC)
- Since there is no explanation of the issue on this talk page, I've gone ahead and deleted it. 192.35.100.1 03:05, 13 November 2006 (UTC)
[edit] removal
I've removed this:
- The Omega symbol is now to be represented as one on the six numbers that formulate the universe founded by Martin J. Rees.The cosmic number omega measures the amount of material in our Universe - galaxies, diffuse gas, and 'dark matter'. Omega tells us the relative importance of gravity and expansion energy in the Universe. A universe within which omega was too high would have collapsed long ago; had omega been too low, no galaxies would have formed. The inflationary theory of the Big Bang says omega should be one; astronomers have yet to measure its exact value.[citation needed]
I don't think this is worthy in it's present state to be in the main text - and it needs i bit of rewriting as well - suggest re-inclusion into the section "omega (upper case)" when it has been properly cited.87.102.36.82 16:04, 22 November 2006 (UTC)
[edit] Association with Death
Why no mention of this?--John 22:01, 25 November 2006 (UTC)
[edit] Removal
I removed this "*The distinctive trade mark of Omega Engineering, Inc." - reasons, firstly it doesn't quite seem to be an omega - though it contains an omega motif, also the Pioneer Corporation used to have an omega as a symbol on its products. Most importantly almost all the references to 'omega in popular culture' are gone - this one is not majorly notable - so it goes too.83.100.158.13 20:26, 14 February 2007 (UTC)
Also this "In automobiles, the 1983 Oldsmobile Omega." - can't even see an omega on this on. Same reasons as above.83.100.158.13 20:30, 14 February 2007 (UTC)
