Now on Display in the Math Library: A Celebration of Fibonacci Day!

11/23 is Fibonacci Day!
The first four numbers of the Fibonacci sequence are 1 1 2 3 (therefore we celebrate on 11/23).

What is the Fibonacci Sequence?

The Fibonacci sequence is a sequence of numbers.  Add the last two numbers in the sequence to get the next number.  The first six numbers of the sequence are 1 1 2 3 5 8, so:
1
1+0=1
1+1=2
1+2=3
2+3=5
3+5=8

And this can go on forever!

To make your own:

Draw boxes using the Fibonacci sequence…

and draw a curve through the diagonals of each box…

VOILA! A Fibonacci Spiral!

All sorts of natural phenomena follow the Fibonacci spiral.

Even our pets can get in on the fun!
