Fibonacci Numbers  A little history  A little sequence  A little biology  A little poetry, architecture & art  How to eat Fibonacci Numbers

 You will understand what the Fibonacci Numbers are and how to generate them.  You will know who Fibonacci was.  You will eat some Fibonacci Numbers

I think Fibonacci is fun: We start with a 1 and a 1 Then 2, 3, 5, 8 But don’t stop there, mate! The fun has just barely begun.
