No cool number days this week. 

But, I just realized there is a whole set of numbers out there I have overlooked – the Fibonacci sequence.  It is easy but elegant.  Start with 0 and 1.  Add them together.  Always add the latest two numbers together to get the next one.  The first 10 numbers in the sequence are:

        0 , 1, 1, 2, 3, 5, 8, 13, 21, 34

(see that 0+1=1; 1+1=2; 1+2=3; 2+3=5…)

Quiz: what is the next number?

For our cool number dates, I am sorry I missed 05/08/13.  Just a month ago, there were three sequential Fibonacci numbers!  Pretty rare… next one is not until 2021, and that is the last one of this century!

 Fortunately, in August there will be some month/day/year combinations that are all Fibonacci, just not presented sequentially. They start with 08/01/13 and end with 08/21/13.  To see how many others there are, check back here on the Sundays from July 28 through August 18. 

Look for a wonderful reference to Fibonacci numbers in the movie “Mr. Magorium’s Wonder Emporium.”
