Editing Talk:2776: Crystal Ball

<!--Please sign your posts with ~~~~ and don't delete this text. New comments should be added at the bottom.-->


I added an explanation of spherical aberration and the tendency of light to distort around spherical objects, as well as the idea of how fisheye lenses use this principle to do their thing. [[User:Darkwolf0218|Darkwolf0218]] ([[User talk:Darkwolf0218|talk]]) 01:01, 16 May 2023 (UTC)

I can't seem to find the citation toolbar while editing on mobile. So dropping this here for a reference to ball lenses on fiber optic cables. {{Cite web}} https://www.edmundoptics.com/knowledge-center/application-notes/optics/understanding-ball-lenses/ [[User:Iggynelix|Iggynelix]] ([[User talk:Iggynelix|talk]]) 12:37, 16 May 2023 (UTC)
:We ''very rarely'' use Cites on this site. Just add a link (in alternate-word form to flow with the sentence, ideally).
:I've never really used toolbar stuff (simple enough to tap in {s, }s, [s and ]s, as well as any &lt;s and &gt;s needed for HTML, etc), and it's simple to (eventually, perhaps checking via Preview that it's not ''totally'' messed up on the first go or two) work out what others did to add references and copy the style of the right kinds of them.
:So if you want to mention a link to [https://www.edmundoptics.com/knowledge-center/application-notes/optics/understanding-ball-lenses/ ball lenses], just do something like this. (PS., use the full <nowiki>~~~~</nowiki> when signing Talk contributions, I fixed yours without using the {{template|unsigned}} 'reminder'..)

Why am I now ear-wormed by "Beware of the Beautiful Stranger" by Clive James and Pete Atkin?

I’m going to edit the part on the title text to be more broad, as Google isn’t the exclusive way to receive any kind of information on the internet [[Special:Contributions/172.69.58.42|172.69.58.42]] 19:35, 16 May 2023 (UTC)

While we can all applaud the connection of spherical aberration to crystal balls, unfortunately the off-axis part of joke misses the mark as spherical aberration is an aberration that is generally uniform across the frame.

: Yes, the comic seems to be confusing spherical aberration with coma, which makes it hard to produce a good explanation.  I think the current reference to fisheye lenses, and distorted shapes, is a red herring.  Spherical aberration rather appears as a lack of sharpness.

I'm new to the whole xkcd's websites and comic strips and I desire to meet some other xkcd fans as well![[User:ArchaRaid|ArchaRaid]] ([[User talk:ArchaRaid|talk]]) 23:29, 16 May 2023 (UTC)
