Crystallography[edit]

Crystallography uses these things to denote whether a plane or direction is being discussed, and whether it's generic or specific. I have put up a basic account of their use in Crystallography#Notation, but you may want to wait a few days for it to stabilize before you copy it into this article. This may also convince someone to finally flesh out Miller index.--Joel 06:14 & :18, 16 May 2005 (UTC)

Usage in chat[edit]

On chatrooms and message boards, actions are put in brackets.

"I know she can't sing, but I like Lindsay Lohan {ducks from flying vegetables}."

There's also the "Insert Item" usage.

"I don't care if [insert nominee here] deserves to be in the hall of fame, I think that Maris should be in."

History[edit]

I came to this article hoping to find out at what date the earliest known usage of brackets occurred in literature. Anyone who edits this might want to consider adding this information. Thank you — Preceding unsigned comment added by 172.218.155.108 (talk) 09:36, 30 October 2015 (UTC)

Braces[edit]

I've just reverted an anon editors claim that "curly bracket" is a colloquial term. I think this is an EngVar issue because, in the UK, "curly bracket" is much more common than "curly brace" (the exceptions being computer books published in the USA). What does anyone else think? I'd be happy to add a note that the use of "curly bracket" is deprecated in American English. Dbfirs 23:12, 24 January 2016 (UTC)

This is NOT an EngVar difference - as shown in the C Programming Language, C++ Programming language specifications. I did not cite the Java Language specification, or the C# language specification, but I could have because it is specified there also that these are "braces". Using "Bracket" or "Curly Bracket" for braces in these languages is *wrong*. I would show my references, but you deleted them! 74.194.78.21 (talk) 23:19, 24 January 2016 (UTC)'

I'd be happy with a note to this effect for the computer term, but this article is about a much wider usage. Dbfirs 23:28, 24 January 2016 (UTC)
I've restored your reference for the computing usage, with apologies for accidentally deleting it. Dbfirs 23:34, 24 January 2016 (UTC)
Still think it needs cleanup, for example - the line that says "Such languages (C being one of the best-known examples) are therefore called curly bracket languages.[19]" points to a page that calls them braces, strangely enough. Every math page I've looked at has denoted they were called braces also. 74.194.78.21 (talk) 23:51, 24 January 2016 (UTC)
I agree it needs cleanup. American math pages will call then braces because of EngVar, but British maths pages call them curly brackets, and the OED says under bracket: "One of two marks of the form [ ] or ( ), and in mathematical use also {}, used for enclosing a word or number of words, a portion of a mathematical formula, or the like, so as to separate it from the context". I'll make a start on cleaning up. Dbfirs 00:08, 25 January 2016 (UTC)

In 20+ years working as a physicist and program manager in Silicon Valley, with hundreds of physicists, engineers, and mathematicians, and including numerous software development efforts, I never once heard anyone call a curly bracket a brace. Not once. "Pointy bracket", yes, very common. Brace, never. So, regardless of what appears in specs or math[s] pages -- and seriously does anyone really think humans talk like those sources? -- "brace" is not common usage here, or anywhere else in the US that a dealt with. — Preceding unsigned comment added by 107.77.213.71 (talk) 12:59, 1 October 2016 (UTC)

Indian terms[edit]

The terms

first bracket ( )
second bracket [ ]
third bracket { }

are commonly used to teach mathematics in India. — Preceding unsigned comment added by RedBookCamel (talkcontribs) 12:20, 13 September 2016 (UTC)

Do you have a reliable source for this? A quick Web search doesn't find anything. --Macrakis (talk) 13:01, 13 September 2016 (UTC)
it is used in common parlance in mathematics classes in india, to ease the way problems are solved. there is a quora question, where it is asked why first brackets and second brackets aren't used in programming, but third brackets - { }, are used. https://www.quora.com/Why-dont-we-use-first-or-second-bracket-in-C-programming — Preceding unsigned comment added by RedBookCamel (talkcontribs) 12:41, 14 September 2016 (UTC)
Not a Reliable Source, I'm afraid. --Macrakis (talk) 03:28, 15 September 2016 (UTC)
