Fibonacci's Real Mathematical Legacy

https://blogs.nature.com/aviewfromthebridge/files/2017/04/fibonacci-827013_640.jpg
For hundreds of years until the ebb of the Italian Renaissance, one name was synonymous with arithmetic. This was Leonardo — not the polymath from Vinci, but Leonardo Pisano (ca. 1170-1250), now popularly known as Fibonacci. Yet we know little of Fibonacci’s life beyond the nickname and his Pisan roots: most details come from a 160-word autobiographical sketch written in 1202. He is often ...
