This coming Saturday is International Pi Day. No, that’s not a typographic error. Pi, not pie, regardless of flavour. Or maybe pi. Usually represented by π, a Greek letter that looks like a wobbly footstool.
It’s on March 14, because if you write it as 3/14, or better yet as 3.14, you have the first three digits of pi. Correctly, pi is 3.141592 plus an endless series of further decimals, but for most purposes, 3.14 will suffice.
But then, pi can never be precise. Mathematicians have calculated pi to 13.3 trillion decimal digits, and they’re firmly convinced that it will never – no, never – repeat a pattern. Which means that no matter how precisely they define pi, the next digit will be unpredictable.
So pi is at once a constant, and a variable.
And yet the universe could not exist without it.

My father was a pretty good painter. While at university in Toronto, he took lessons from A.Y. Jackson and others of the famed Group of Seven. But as the years passed and his life got taken over, more and more, by academic studies in psychology and religion, he grew more and more cautious in his use of paint.
One day, a friend who was also a painter dropped in. She watched him working with fine brushstrokes and tiny dabs of paint. She squeezed flaming magenta onto his palette. She took his brush. She slapped a blob of magenta onto his canvas.
It stood out like an erupting volcano.
“There!” she commanded. “Paint to that!”
To his credit, my father did. A single blob of vivid colour changed that painting. And all the paintings\ he did thereafter.
