Saturday, March 14, is Pi Day, mainly because the date corresponds with the first three numbers of pi — 3.14.
You might recall from high school geometry that pi (π) is the Greek letter that represents the ratio of the circumference of a circle to its diameter. Remember how much fun that was?
Still, Pi Day gives math geeks everywhere a reason to raise their eyes from their programmable calculators and say “Woohoo!” Or whatever it is that math geeks say when they’re partying.
Here are some suggestions for celebrating Pi Day:
• Measure the circumference of someone you love.
• Find a radius you like and share it family and friends.
• Draw lots of perfect circles — freehand.
• Take a paper circle and cut it in half. Fold those two halves in half. Fold them in half again. Place the two pieces together to form a heart shape and tape them together. Color the heart shape red and give it to someone you like.
• Throw away all paper hearts you get today.
