If this wasn’t so, if there was no such thing as pi-well, our lives would be much the poorer. After all, the reason we find these formulae so fascinating is the existence of pi as a number that is of some serious significance to our lives, mathematical or not. Still, this column is not really about the genius of Ramanujan. This is actually a special case of a more complex Ramanujan formulation that calculates pi to any accuracy you might want. This produces a number that matches pi to 6 decimal digits-good enough for almost any calculation you might need. Divide the result by the square root of 8. Cue the question Ramanujan-watchers have been asking for a century: how did the man come up with this? With his other remarkable formulae?įor one more example, there’s this approximation: divide 9,801 by 1,103. It’s only from the 19th digit that it differs. Incredibly, Ramanujan’s formula gives us a number that isn’t pi, but matches the first 18 decimal digits of pi. In fact, if you now press the button with the symbol for pi on your calculator, I bet none of the digits you see will change. What you see on your calculator is a number astonishingly close to pi. Of the result, take the natural logarithm (“ln"-never mind what it means, but your calculator will have a button, so press it). Here’s a description of one of them that you can tap out on your nearest calculator: Add the square roots of 72, 90 and 80. If you know anything about him, you know that through his short life, he churned out endless exotic formulae that mathematicians are trying to understand even today, a century after he died. Before I do, a reminder of the great Srinivasa Ramanujan. In passing, you would not call any of those approximations to pi a “nice round figure", I’m sure. So, 3.14 is indeed an approximation-a reasonably good one, but an approximation all the same. Accurate to the first 10 places after the decimal point, pi is 3.1415926536. So it is, as you no doubt know, close to but not actually pi. In this bill, what the man added as a tip was $3.14-and 3.14 is, of course, the fraction 314/100. Another way of saying that is that its decimal expansion never ends. That means it cannot be expressed as a fraction. To begin with, it wasn’t really pi he added as a tip. Bush sings pi to its 137th decimal place, but omits the 79th through 100th decimal places of pi for unknown reasons.Those are actually questions I find fascinating. Progressive rock musician Kate Bush performed a song titled π on her 2005 album Aerial. X Research source Technically "Pi" is only the protagonist's name, but it has gotten people thinking about pi. You could also watch the film Life of Pi. Try the film π-it's an interesting and dark movie about a mathematician who goes crazy, but intended for an adult audience only. Write a pi-themed song and sing it, or write a short pi-themed skit and act it out.Write either a pi-ku (haiku) or a regular pi-em (poem) to show how much you love pi. Here are a few ways to celebrate pi artistically: You don't have to create art to celebrate pi you can also just appreciate art that already celebrates it. And even if you're not the world's most talented poet or writer, you can still have fun while being silly. You can use your creative side to show how much you love and appreciate pi. You don't have to be a left-brained thinker to fully celebrate pi. If you want to really show your dedication on Pi Day, learn to memorize pi in advance by studying as many of the digits of pi as you can. As soon as someone loses, you can hit him in the face with a pie. Have a pi memorization or recitation contest.Play an Einstein-themed trivia game, or have an Einstein impersonator contest. Pi Day also happens to be the birthday of Albert Einstein.You can also hide objects representing the digits of pi: three baseballs, one frisbee, four basketballs, etc. Hide pi-themed objects around your classroom, home, or other celebration venue. They should be related to geometry, trigonometry, or other fields where pi is particularly useful. Come to Pi Day with at least ten math questions you can spring on people.
