Today (and every day) is a great day to eat pie. And if you’re worried about calories or carbohydrates, don’t be. Math says it’s OK to indulge because it’s #PiDay !
π, or pi, is the ratio of a circle’s circumference to its diameter. Pi is numerically represented as 3.14 (or 3/14 for those following the MM/DD format) and is an irrational number, meaning its exact value is impossible to figure out. Computer scientists, however, have been able to calculate billions of digits of pi. But because there is no recognizable pattern in pi’s digits, we could continue calculating the next digit (and the next, and the next) for millennia—and still not get to a final digit.
Pi’s ubiquity goes beyond math. The number also shows up in the natural world. Look no farther than the disk of the moon, the pupil of an eye, the spiral of the DNA helix, or the concentric rings that travel outward from stones skipped on a pond. And perhaps, pi may also be in that bite of 🥧 you take today. — @scicomm_ana, NOVA digital associate producer
