Uppercase Gamma (Γ)
- Unicode: U+0393
- HTML Code: Γ or Γ
- Alternative Names: Capital Gamma, Upper Gamma, Majuscule Gamma
- Historical Origin: Derived from the Phoenician letter Gimel (𐤂), which represented the sound /g/
- Description: The uppercase Gamma resembles an inverted "L" and is the third letter of the Greek alphabet. Its simple yet distinctive shape has made it a popular choice for representing various mathematical and scientific concepts.
- Cultural Significance: In ancient Greek, Gamma represented the /g/ sound and was one of the earliest letters adopted into the Greek alphabet.
Lowercase Gamma (γ)
- Unicode: U+03B3
- HTML Code: γ or γ
- Alternative Names: Small Gamma, Lower Gamma, Minuscule Gamma
- Historical Development: Evolved from the cursive form of the uppercase Gamma during the development of Greek handwriting
- Description: The lowercase gamma resembles a "y" without the upper portion of the loop. Its curved tail and distinctive shape make it easily recognizable in mathematical and scientific notation.
- Modern Usage: Widely used in mathematics, physics, and engineering to represent various quantities and concepts.
