Corner Brackets
Corner brackets, also known as angle brackets, are punctuation marks with the form ⟨ ⟩ or < >. They serve a variety of purposes across different fields, including mathematics, computer science, linguistics, and writing.
Material
Corner brackets are not physical materials themselves, but symbols represented in various mediums:
- Typography: Typically rendered as part of a font set.
- Digital Text: Represented as characters within a character encoding standard (e.g., Unicode).
- Handwriting: Drawn as angular symbols.
Purpose and Function
The function of corner brackets depends heavily on the context:
- Mathematics: Used to denote inner products, linear algebra operations (e.g., vector spaces), and sometimes to indicate intervals.
<a, b>
might represent the inner product of vectors a and b. - Computer Science:
- HTML/XML: Used as delimiters for tags, defining elements and attributes.
<p>This is a paragraph.</p>
- Programming Languages: Used in various contexts, including generics (e.g.,
List<String>
), templates, and type annotations. - Data Structures: Used to represent relationships or pointers.
- HTML/XML: Used as delimiters for tags, defining elements and attributes.
- Linguistics: Used in the International Phonetic Alphabet (IPA) to denote phonetic transcriptions.
/ˈhɛloʊ/
represents the pronunciation of "hello". - Writing/Grammar: Less common in standard prose, but sometimes used to enclose stage directions in scripts, or for specific stylistic effects.
- Physics: Used in Dirac notation (bra-ket notation) to represent quantum states.
<ψ|
represents a bra vector.
Usage Scenarios
- Writing Code: Defining HTML elements, declaring variables in programming languages.
- Mathematical Notation: Expressing vector operations, defining sets and intervals.
- Phonetic Transcription: Representing the sounds of speech.
- Scriptwriting: Indicating character actions or settings.
- Scientific Papers: Presenting quantum mechanical calculations.
- Data Exchange Formats: Defining elements in XML or JSON.
Common Types/Variations
- Angle Brackets (< >): The most common form, used extensively in HTML, XML, and general programming.
- Single Angle Brackets (< or >): Sometimes used alone, particularly in mathematical inequalities (e.g.,
x > 5
). - Double Angle Brackets (≪ ≫): Used in mathematics to represent very much greater than or less than.
- Floor and Ceiling Brackets (⌊ ⌋, ⌈ ⌉): Used in mathematics to denote the floor and ceiling functions.
- Bra-Ket Notation (< | >): Specific to quantum mechanics, representing vectors and their duals.
- Chevrons (⟨ ⟩): Often used interchangeably with angle brackets, especially in mathematical contexts.
Corner brackets are metal fixtures used to connect materials at angles, providing support and reinforcement. They find applications in construction, furniture assembly, and various DIY projects.
