I suppose it’s been obvious, though I had been oblivious. The link between pi, that uncalculatable number starting with 3.14, and pie, the flexible food item that can be the main course (pot pies) or dessert (fruit pies), goes far beyond the homonym relationship.
Most pies are created in a mixing bowl, one that comes in a rounded shape, and then is placed in a pie pan, usually circular in design. Even the cutesy ones, such as those made in the shape of a heart, generally have rounded edges.
Pi, of course is the defining term for the circumference (2πr) or area (πrr) of a circle.
And everyone knows that the circle is perfect; it has no beginning and no ending.
Here’s a link to TeachPi.org, “the first and best place on the Web for teachers who want to find or share ideas for Pi Day activities, learning, and entertainment.”
His blog led me to The World Needs More Pie by Beth Howard, with the tag, “Give a piece a chance.” To that end, she writes:
Why We Should All Bake Pies
“Pie makes people happy. Happy people want to do nice things for others. When everyone is doing nice things for each other all the time there can be no war, and therefore pie can save the world.”
And maybe it can.
