Fibonacci Day

Happy Fibonacci Day!

Leonardo Bonacci of Pisa, also known as Fibonacci, was an Italian mathematician in the early 13th century. Although he did not discover the sequence bearing his name, Fibonacci introduced it into western mathematics.

The Fibonacci Sequence:

The Fibonacci Sequence

Each number in the sequence is the sum of the two preceding numbers. For example:


This makes it a recursive sequence. The Fibonacci Sequence is probably the oldest known recursive sequence! Today, the sequence is usually written with the leading zero, but historically, zero wasn’t included. (Learn more about the mysteries of zero.)

Fibonacci Sequence

Notice the first four digits: 1, 1, 2, 3. They match today’s date, November 23rd, especially when written in the format 11/23.

Revel in the Fibonacci sequence at 11:23:58 a.m. or p.m. (plus the seconds!) in order to get six numbers of the sequence in a row!
