Just like normal people celebrate Valentine's Day or Independence Day, geeks around the world will gather and join hands in the shape whose ratio of its circumference to its diameter is the most revered mathematical constant in the known universe.
Fun things you can do today is to convert things into pi. This step is absolutely necessary for two reasons: To utterly confuse people who have no idea what you are talking about (thus opening the door for enlightenment) and to have fun seeing how many things can be referenced with pi. Consider two approaches:
- Convert naturally circular things into radians like the hours on the clock. Instead of it being 3 o'clock, now it's 2*pi o'clock. Or, instead of it being 3 o'clock, convert the inclination of the sun into radians and describe that as the time.
- Simply use 3.14 as a unit of measure. Instead of being 31 years old, you are 9pi years old (approaching your 10th birthday). With this same approach, you can find out your next pi birthday (don't forget to celebrate it when it comes!).
