497978399450752495Saturday is all about pi  … not the delicious fruity treat, but the mathematical symbol that expresses the ratio between a circle’s circumference and its diameter. As you may recall from geometry class, the shorthand is 3.14, but the number in fact is infinite, never repeating. And its first 10 digits are 3.141592653 — or 3.14.15, 09:26:53. That happens twice on Saturday: at 9:26 and 53 seconds on March 14, 2015, a.m. and p.m. So how should you celebrate? I suggest with a pieces of pie … and this time I do mean the fruity treat. Or watch the awesome film Life of Pi.
