Tech & Science March 14 is Pi Day, a chance for people around the world to celebrate everyone’s favorite mathematical constant "π" (pronounced like the word “pie.”) Pi is an incredibly important number in many fields because it is used to represent the ratio of a circle’s circumference (the distance around its edge) to its diameter (the distance from one edge to another measuring straight through the center.) The value of Pi is always the same no matter the size of the circle—approximately 3.14. Pi is an irrational real number, meaning it cannot be fully expressed, and continues on infinitely. For millennia, humans have tried to calculate Pi to ever greater decimal accuracy, an endeavor which has been pushed to the extremes by the advent of modern technology. A Google developer—Emma Haruka Iwao—recently broke the world record for calculating the constant, working it out to an astonishing 31.4 trillion digits using a … [Read more...] about Pi Day 2019: Jokes Celebrating The Famous Mathematical Constant

BySteven Strogatz March 14, 2019 Adapted from “ Infinite Powers: How Calculus Reveals the Secrets of the Universe ,” which will be published on April 2 by Houghton Mifflin Harcourt. When my children were young, they liked to stare at a pie plate hanging in our kitchen, with the digits of pi running around the rim and spiraling in toward the center, shrinking in size as the numbers swirled into the abyss. Pi, as we all learned in school (and are reminded every March 14, on Pi Day), is defined as the ratio of a circle’s circumference to its … [Read more...] about Pi Day: How One Infinite Number Made Us Modern
