Talk:Theta

Spanish name
Studying an interwiki says that this letter's name is zeta in Spanish. Is this right?? Georgia guy 23:50, 12 November 2005 (UTC)

Yes but the Spanish name for Zeta is Dseta Geego 19:15, 25 February 2006 (UTC)

Perhaps they thought this because in Spain, you use thetas, named after the letter zeta, pronouced "theta". DarkestMoonlight (talk) 21:17, 22 April 2008 (UTC)

ϑ
I don't think this is to be considered a good article. It misses to discuss the ϑ, an alternative version of theta. Maybe someone can comment on why there are different versions and when to select the appropiate one. --Abdull 13:15, 15 June 2006 (UTC)

Capital theta picture
Capital theta does not simply have a line through it, it has a line that is narrow at the middle. There should be a picture of capital theta, such as this: http://www.mathmlcentral.com/characters/glyphs/CapitalTheta_L.gif

 * For the most part, I would consider the article well written except for some glaring areas like the title Uses as names and the 3 disjointed "mini-paragraphs" at the end of the Lead section.
 * There are two references listed on the bottom but it hard to see what parts of the article that they verify or even where in those references the verification can be found. Some in-line cites would be of huge benefit to the article. I tagged the statements with the most pressing need for a cite.
 * The section Uses as names (in addition to being grammatically awkward in title) is a bit thin. I'm partially not convinced of its value to the article in the first regard, but if it is meant to be included I do think there needs to be more example and also some source commenting on how the particular name has some meaning.
 * Are there any modern uses of Theta? (From Greek sorority/fraternity or Science/Medicine use?)
 * I don't know how much POV could be interjected into an article about a Greek letter but this article is distinctly NPOV.
 * The article is exceptionally stable.
 * The article does a good job of illustrating the Theta symbol.

Pronunciation
Surely the Modern Greek pronunciation is [θiːta], not [θiːtə]? 85.8.12.78 06:46, 17 June 2007 (UTC)

Should we add...
OK, so in Doctor Who, The Doctor's name in Time Lord university was Theta Sigma. Of course this isn't really notable, but just thought I'd ask:)

The letter theta has huge importance in Scientology where it represents both "impersonal" life force (actually called theta) and an individual human spirit, which Scientologists call the "thetan".Slarty1 (talk) 05:39, 4 May 2018 (UTC)Slarty1 (talk) 05:40, 4 May 2018 (UTC)

Regarding "In options investing"
Removed the following text..

In options investing
Theta is known as an option Greek measuring the rate of time decay on a daily basis. One can look at this as an ice cube melting in your hand. A Theta of &minus;.05 means that the option is losing a nickel of time value each day. Other option Greeks include Delta, Vega, Rho and Gamma.

________________________

Replaced it with..

One of the variables known as Greeks (finance), representing the lost-value rate of an option over time.

ϴ and Θ
Can someone explain why ϴ and Θ exist as capital Theta symbol and how, except for the obvious look, they differ from each other? (Their HTML entities are &amp;#920; respectively &amp;#1012;) Thank you. 77.57.214.3 (talk) 08:09, 29 August 2009 (UTC) (lKj)
