Spherical cap and Dome (mathematics) are the same mathematical object. The two pages should be merged. Unfortunately they use different notation. Spherical cap seems currently to be the better article and probably has the better name. -Ian Jackson 18 Oct 2011
I absolutely agree with Mr. Jackson. The Spherical Cap discussion has a diagram (!) which makes it easier to relate the cap to the sphere. Joe Smart 16 Dec 2011 email@example.com — Preceding unsigned comment added by 22.214.171.124 (talk) 02:27, 16 December 2011 (UTC)
I have concerns about this suggestion. It depends on the indexing. I approached the problem looking for "spherical cap", and found what I was looking for. However, had I been looking for information on the volume of a dome, I would not have thought of using the term "spherical cap" (nor vice versa). The equations are different in approach, too. If the two can be combined without truncation (and the result would be some duplication), and if both terms can be found in a search, then combine. But simpler to leave as is.
Colors!! Not visible to people with typical 'color blindness' issues.
The illustration of the sectioned sphere on the page: http://en.wikipedia.org/wiki/Spherical_cap shows the sphere divided into two pieces. The illustration has the caption: "The spherical cap is the purple section." The text also states: "The blue section of the illustration is also a spherical cap."
This is fine for people with 'normal' color vision, but for the large percentage of people with the typical vision aberration known as 'red/green' color blindness there is NO DIFFERENCE in the colors. Both sections of the sphere look identically 'blue'.
I recommend you use blue as the color for the cap and use red for the rest of the sphere.
I also recommend that writers and editors of Wikipedia articles become familiar with the guidelines for creating webpages that are 'color equal'. You can 'google' the topic.
