Notacija

Notacija is a system of symbols used to represent information or concepts within a domain. It encodes ideas in a compact, precise, and portable way, enabling communication, calculation, and automation. Notacija comprises systems that have defined rules of syntax and semantics; the same string means the same thing in a given system, and different systems use different symbols.

Notacija appears in many fields. In mathematics and science, notation includes symbols for operations, relations, and structures, such as +, −, ∑, ∫, and conventions like superscripts for exponents. In music, musical notation uses staff lines, notes, rests, dynamics and tempo marks to encode sound. In chemistry, formulas and structural representations convey composition and bonds. In linguistics, phonetic and grammatical notations (e.g., IPA) transcribe sounds and structures. In computer science, programming languages and formalisms use syntax rules to define valid programs and data.

History and standardization: Notation has evolved from mnemonic marks and alphabets to highly abstract symbols. Some systems become de facto standards through widespread adoption (e.g., Arabic numerals, Unicode). Standards bodies (ISO, IEC, IETF) and field-specific communities maintain notation conventions to improve interoperability, teaching, and research.

Practical notes: Good notation is precise, unambiguous, compact, and learnable. It often balances symbolism with readability and may be adapted to new theories. Notation continues to evolve with technology, enabling computer-assisted reasoning, typesetting, and digital encoding.
