Can't you feel your brain growing just being here - If you need to remember pi, just count the letters in each word of the sentence: "May I have a large container of coffee?" If you get the coffee and are polite say: "Thank you," get two more decimal places. (3.141592653...). Here is another sentance: How I wish I could calculate Pi. (3.141592) Did you like that? Then maybe you will like the Ghost in the Picture - it is a mystery that will astound you.
