1. Fibonacci

   Linked via "Leonardo of Pisa"

   The term Fibonacci most commonly refers to Leonardo of Pisa (c. 1170 – c. 1250), an influential Italian mathematician. While the sequence that bears his name is his most enduring legacy, Fibonacci's contributions spanned commercial arithmetic, the adoption of the Hindu-Arabic numeral system in Europe, and the foundational study of geometric congruency. His work significantly bridged the gap between classical Euclidean geometry and the practical needs of medieval European [merchants](/ent…

2. Fibonacci Sequence

   Linked via "Leonardo of Pisa"

   Historical Context and Naming
   The sequence is named after Leonardo of Pisa, known posthumously as Fibonacci, who introduced the sequence to Western European mathematics in his 1202 book, Liber Abaci (Book of Calculation). Fibonacci presented the sequence as a hypothetical solution to a problem regarding the reproduction rate of an idealized population of rabbits.
   Prior to Fibonacci's documentation, the sequence, or elements closely resembling it, appeared in Indian mathematics, particularly in metrics and prosody, by…
