Talk:Roundness (geology)

A translation

Here is a translated version - using Google translator. I am sure it will need to be worked on and "smoothed out". Google translator is not perfect for syntax. However, this is a small article and maybe easy to fix. Also the references seem to have translated into English. However these are not imbedded in the text at this time. Someone will have to compare both translations to figure out where the citations go for the references. And other references, can of course, be added. I can see this is a valuable article. ---- Steve Quinn (talk) 18:08, 16 September 2010 (UTC)

This article is a rough translation of a Russian Wikipedian article. The text, grammar, syntax, and spelling may need to be worked on in order to improve this article. Your help is appreciated.. Please improve this article if you can.---- Steve Quinn (talk) 18:20, 16 September 2010 (UTC)

Merge proposal

Please see the merge proposal at Talk:Rounding (sediment) and discuss a content merge there. Vsmith (talk) 14:10, 25 September 2010 (UTC)

• Very simular! But where is my Foto "File:Эллипсоид со спичками2.jpg

Very good roundet rock from the beach of Teletskoye Lake, Altai, Russia. Picture A.N. Rudoy (Alexei Rudoy)"?Heljqfy 22:56, 25 September 2010 (UTC)--Heljqfy 22:56, 25 September 2010 (UTC) —Preceding unsigned comment added by Heljqfy (talk • contribs)

I've merged the two articles here and removed quite a bit of google translate stuff as raw google translations should never be dumped into an article and left. I've fixed a bit, but need more verifiable (preferably English) references. The stuff removed can be seen in the article history for anyone wishing to work with it. More to be done - later. I've also removed the image link for the non-working image mentioned above - no idea where it is, if located it can be reincluded. Vsmith (talk) 15:04, 28 September 2010 (UTC)

I believe the image is can be accessed through the Russian Wikipedia article. However, it may not be signifigant enough to retrieve it somehow. I am curious, though. I thought all the Wikipedias store images at Wikipedia Commons. It may be that this is stored on the Russian Wikipedia site. ---- Steve Quinn (talk) 23:27, 28 September 2010 (UTC)

Move to Roundness (sediment)?

This is article is about roundness of sediment, as used in earth sciences disciplines, including—but not exclusive to, geology. Move to a more generic name? +mt 21:51, 28 September 2010 (UTC)

See the merge discussion at Talk:Rounding (sediment). That stub prior to the merge as well as this one were strictly about geology topics, mainly sedimentology. As other geological processes involve rounding I merged here to include the non-sediment topics. The article is still a work in progress. For particle rounding used in other fields we can add a disambiguation link at the top. One obvious topic is rock or gemstone tumbling used to round and smooth specimens - and that would fit here as related to rock/minerals, as there exists an article there I'll add it as a see also link. Didn't think of that previously. Vsmith (talk) 23:05, 28 September 2010 (UTC)

There exists Roundness which is a disambiguation page and I've added it to the top of the page for those other uses. Vsmith (talk) 23:20, 28 September 2010 (UTC)

Mathematical derivation?

Is there a mathematical formula to derive an object's roundness? Something that would involve calculus I assume, but Sphericity has such a nice definition, it would be nice to have one for roundness. --vossman (talk) 04:32, 18 March 2011 (UTC)

Merge with Sphericity scale

There's a proposal for merging this with Sphericity scale. Maybe the proposer could elaborate why this is a good idea? In my opinion, the fact that the two topics are easily confusable and somewhat related isn't enough to warrant treating them in a single aricle. – Uanfala 18:19, 17 August 2017 (UTC) Adding that a different merger – between Sphericity and Sphericity scale – would seem reasonable at first sight. – Uanfala 20:02, 17 August 2017 (UTC)

Now that I have read the article with more calm I have retract the merge proposal (supposing the largelly unsourced article is correct). I support the merge between Sphericity and Sphericity scale Uanfala suggests. Lappspira (talk) 12:56, 21 August 2017 (UTC)
