Don't get it? "For fans of numerical information or the history of mathematical discoveries," writes poetry blogger Edward Byrne, "March 14 represents a day of celebration. Since the date may be written as 3-14, the digits correspond with 3.14, the opening series of digits associated with 'pi.' (The pi moment during the day is at 1:59, more fully reflecting the start of pi: 3.14159.) This irrational number—one that never can be stated exactly because its decimal sequence continues to infinity—always has amazed mathematicians and held a primary position of curiosity for many non-mathematicians."
