Definition

1. Proper noun (Computing):

   • A high-level programming language: A programming language designed in the late 1950s, significant for its influence on later languages. It was created to express computational procedures clearly and precisely as algorithms.

2. Proper noun (Astronomy):

   • A star in the constellation Perseus: The second-brightest star in the constellation Perseus. It is a famous example of an eclipsing binary star system, where two stars orbit each other and periodically block each other's light from Earth's perspective.

Usage Examples

• Proper noun (Computing):
  • The ALGOL language introduced key concepts like block structure and lexical scoping.
  • Many modern programming languages, such as Pascal and C, were heavily influenced by ALGOL.
• Proper noun (Astronomy):
  • The star Algol is also known as the "Demon Star" due to its variable brightness.
  • Astronomers study Algol to understand the dynamics of eclipsing binary systems.

Advanced Usage

• "ALGOL 60": Refers to the highly influential 1960 revision of the ALGOL programming language, which became the standard version.
  • The ALGOL 60 report formalized the language's syntax using Backus-Naur Form (BNF).
• "Algol Paradox": A historical puzzle in astronomy concerning the evolution of the Algol binary system, where the more massive star appeared to be the less evolved one.
  • The Algol paradox was resolved by understanding mass transfer between the two stars.

Variants and Related Words

• ALGOL-like (adjective): Describing a programming language or syntax that resembles or is derived from ALGOL.
  • The language has an ALGOL-like syntax with begin and end blocks.
• Algol variable (noun, astronomy): A class of eclipsing binary stars whose properties are similar to those of the star Algol.
  • Several Algol variables have been discovered in other galaxies.

Synonyms

• (Computing): Algorithmic Language (the full name).
• (Astronomy): Beta Persei (its Bayer designation), the Demon Star.

Related Phrases / Terms

• (Computing): "ALGOL dialect": A specific variant or implementation of the ALGOL language (e.g., ALGOL 68, ALGOL W).
  • Burroughs computers used their own extended ALGOL dialect.
• (Astronomy): "Algol system": Refers specifically to the binary star system of Algol.
  • The Algol system has an orbital period of about 2.87 days.
