The shape formed by the intersection of two circles is called a lens. Lenses are also of interest to astronomers for telescope manufacture. A lens shape causes spherical aberation when used as an optical element, leading to the use of aspheric lenses and mirrors on higher quality telescopes.

− | Uhhh, the first commenter has a point, that's not how Venn diagrams work. The left circle is labelled as the set of "set theorists", the right circle is the set of "astronomers", making the joined section the set of "astronomer set theorists", i.e. people who belong to both sets. As a Venn diagram this should be ONE circle, the set of "People who get excited by this shape", with "set theorists" and "astronomers" inside it, and as one circle it WOULDN'T have this shape, LOL! I guess a second circle to make this shape, "People who enjoy space" for example, then put "astronauts" in it, and move "astronomers" to the junction? Or these are set names of | + | Uhhh, the first commenter has a point, that's not how Venn diagrams work.

Or these are set names of ''aspects'' of these professions, like "study the night sky" for Astronomers, "math experts" for Set Theorists (IDK, LOL!), with the Excited thing being an aspect they have in common... I think the explanation needs to be updated to note that the Venn diagram was made somewhat wrong... [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 06:46, 29 April 2023 (UTC) |
