[edit] Clean up 2006/05
This article has a whole heap of 'stuff' about the word umbra. Perhaps most of it could be put on an disambiguation page and the core of the article becomes umbra, with reference to shadows, as it once may have been intended? POds 03:58, 5 May 2006 (UTC)
[edit] Disambig?
As mentioned, it has a whole heap of meanings lumped onto one page. I tired seperating them out as best I could. However I feel that the main focus of this page is the use of Umbra in an astronomy/physics sense, as in dealing with light sources. Therefore, I propose a disambiguation page for Umbra, so that the other topics mention can be elaborated on as well. Stovetopcookies 04:41, 5 May 2006 (UTC)
- I made the disambig page and moved everything there. Since this article is short, and because their definitions depend on one another, perhaps umbra and penumbra should be merged into one article (like deferent and epicycle)? --Fastfission 21:42, 5 May 2006 (UTC)
In law you would use penumbra so it is important to possibly seperate that out as well.
[edit] Sorry.
I am still new to this but I happend upon it when I was trying to point someone in the right direction. It is important because when you discuss law it is a term clarifying that the right is not in the constitution but in the penumbra.
[edit] merge umbra and penumbra
It looks like both these words have lots of uses, but they do also have very specific definitions, as parts of shadows. How about:
- the definitions go to Wiki Dictionary
- we add a disambiguate page for penumbra (instead of the list of other meanings)
- the eclipse and sunspot specific uses of umbra, penumbra, and antumbra go to the articles on eclipses and sunspots
