Talk:Folding

With numbers

What about the term "fold" used with numbers? As in, "It increased three-fold." — Emiellaiendiay 07:41, 18 February 2007 (UTC)

That's a good question - that definition is in Wiktionary under -fold.

A search for "n-fold" brings up entries such as Rotational symmetry and other mathematics-related topics. Maybe an article by that name would be in order. --George100 15:56, 3 August 2007 (UTC)

After searching for this very topic, and not finding it from this DAB, Duckduckgo directed me to Fold change. I have added it here now. 104.159.112.162 (talk) 18:04, 29 May 2021 (UTC)

The poster-child for the Dict-Defs Dab page

Wow, here it is! I'm not sure i've ever seen a collection this large with so many failures to conform to WP:MoSDab. (Since piping of lks is used fundamentally differently in dabs from how it is in articles and lists, i've screwed with the piping in a way that is easier to understand than to explain.

My approach to it is intended to be simultaneously sweeping and cautious, and is two-sided in another sense: only a small part of it should be reorganized into a new dab or two, at Fold and/or Folding, but the rest needs at least to be checked, sooner or later, for coverage at wikt:Special:Search. I'm making a subsecn on this talk page out of each entry, and signing only the ones i express myself about.

• Hmm. I think the "folding" of a business is an adaptation of folding in poker (which in turn presumably is a metaphor for collapsing the "fan" of cards -- "card fan" at Fan#Aerodynamics Ventilation -- in one's literal and figurative hand much as one collapses a fan by re-folding it). My 30-y.o. 8th Webster's Collegiate says

"to bring to an end"

and

"to fail completely: COLLAPSE; esp : to stop production or operation for lack of business ..."

(which makes me picture a load-bearing metal structure failing by bending nearly 180 degrees).
Merriam-Webster's Online Dictionary says at concise.britannica.com/mwu/popup?hdwd=fold&book=Dictionary&jump=fold[3%2Cverb]&list=fold[1%2Cnoun]%3D399414%3Bfold[2%2Ctransitive+verb]%3D399433%3Bfold[3%2Cverb]%3D399461%3Bfold[4%2Cnoun]%3D399478%3Bepicanthic+fold%3D342206%3B-fold%3D399495 (don't try to make that a ext lk!)

7 a : to concede defeat by withdrawing (one's cards) from play (as in poker) b : to bring to an end

and

1 : to become doubled or pleated
2 : to fail completely : COLLAPSE; especially : to go out of business
3 : to fold one's cards (as in poker)

So fold covers shutting down to, for instance, prevent looming insolvency, something that probably occurs more often (tho with less publicity than a bankruptcy. The question is whether a user would (except from not knowing where it's reasonable to look for dict-defs) type "fold" seeking info on bankruptcy in an encyclopedia. I think not, and that this entry is just another symptom of endemic dictdefosis.

Folding in cooking

Folding in cooking refers to a gentle mixing technique, somewhere between a cutting motion and a stirring motion, used to incorporate ingredients into a batter or other mixture, such as for a cake.

• That would be Batter (cooking), but it is an unsuitable lk, since it doesn't even use the word. Cake does cover the right sense, but again doesn't know "fold..." is relevant to it. Sounds like a dictdef to me; probably too much limited to "how to" application to be encyclopedic.
  --Jerzy•t 23:02, 5 November 2008 (UTC)
  
  • Dropped as dictdef.

Fold and Folding as separate Dabs

I've split a Dab along those lines at least once before, restoring the distinction between Fold and Folding. Users who don't realize that we do not name articles with verbs (unless one is an article about the corresponding verb itself, rather than about the action it refers to) will occasionally be inconvenienced by typing "fold" in search of information about folding one or another thing, and then having to follow a See-also entry's lk to Folding. But that is more efficient than every user who needs dab'n of Fold having to deal with a larger page bcz of the Folding entries being included.
--Jerzy•t 07:30, 6 November 2008 (UTC)

Good work Jerzy. Yes, I (only) dropped Mathematics of paper folding, and mistakenly omitted dab tag. You are right too, this is close to being cleaned-up. Widefox (talk) 13:32, 8 November 2008 (UTC)

• Thanks. But would i be right to assume that you misplaced that statement, and that you are not commenting one way or the other one the subject of this section? In that case, it would be good to strike it thru, thus (but not remove it, which confuses the process of checking for talk-page vandalism), and comment in some other section if you want responses to it.
