Pi Day

Every year on March 14th, my oldest son, Peter, makes a pie.  He is a math nut and calls the day "Pie Day" because of the way the date is rendered in numerical form.  The first three digits of Pi are 3.14 or March 14th. 

To celebrate Pi Day, relax and enjoy an ice cold Coke with a slice of apple pie and let your inner math geek go to work to see how many digits of this infinite series you can memorize.  At one point, Peter had memorized Pi to 100 digits.
