This is my Pi Day post for 2021. Every year on March 14th (written 3/14 in the US), geeky mathematicians and their friends celebrate "all things pi-related" because 3.14 is the three-decimal approximation to pi. Most years I write about lower-case pi (π), which is the ratio of a circle's

Recently, I saw a graphic on Twitter by @neilrkaye that showed the rapid convergence of a regular polygon to a circle as you increase the number of sides for the polygon. The author remarked that polygons that have 40 or more sides "all look like circles to me." That is,

It's time to celebrate Pi Day! Every year on March 14th (written 3/14 in the US), math-loving folks celebrate "all things pi-related" because 3.14 is the three-decimal approximation to the mathematical constant, π. Although children learn that pi is approximately 3.14159..., the actual definition of π is the ratio of

Mathematik im Alltag, da denkt jeder sofort an die Rechnung im Restaurant, die man mal schnell per Kopfrechnen aufteilen will. Oder an Dreisatz, Prozentualrechnung, jaja … Für viele Leute kein Problem, aber irgendwie negativ besetzt. Das muss sich ändern! O. k., da wird nun kein gesetzlicher Feiertag rausspringen (wobei DAS jeden

Welcome to my annual Pi Day post. Every year on March 14th (written 3/14 in the US), geeky mathematicians and their friends celebrate "all things pi-related" because 3.14 is the three-decimal approximation to pi. Pi is a mathematical constant that never changes. Pi is the same value today as it

It is time for Pi Day, 2017! Every year on March 14th (written 3/14 in the US), geeky mathematicians and their friends celebrate "all things pi-related" because 3.14 is the three-decimal approximation to pi. This year I use SAS software to show an amazing fact: you can find your birthday

Math lovers, do you know what day it is? It's Pi Day, which we celebrate every year on March 14 because the date 3-14 matches the first three digits of pi, 3.14. This year, I'm celebrating with poetry, combining my love of math with my love of language. Word Spy explains that a pi-ku is

Today is March 14th, which is annually celebrated as Pi Day. Today's date, written as 3/14/16, represents the best five-digit approximation of pi. On Pi Day, many people blog about how to approximate pi. This article uses a Monte Carlo simulation to estimate pi, in spite of the fact that

With Pi Day coming up on 3/14, I wanted to make sure all you SAS programmers know how to use the pi constant in your SAS code... All you have to do is use constant("pi") in a data step, and you've got the value of pi out to a good many decimal places

Saturday, March 14, 2015, is Pi Day, and this year is a super-special Pi Day! This is your once-in-a-lifetime chance to celebrate the first 10 digits of pi (π) by doing something special on 3/14/15 at 9:26:53. Apologies to my European friends, but Pi Day requires that you represent dates

Pi is the ratio of a circle’s circumference to its diameter. Although it is a non-terminating, non-repeating number, the decimal approximation 3.14 and the fraction 22/7 are typically used to represent the irrational mathematical constant. The Greek letter π, was first used as the symbol for pi in 1706 by

Ever since the ancient Egyptians, teachers have celebrated March 14th with a combination of pastry and math. The 18th century addition of the Greek symbol π to represent the ratio of the circumference of a circle to its diameter gave the number 3.14 a unique gravitas all its own. This

Many geeky mathematical people celebrate "pi day" on March 14, because the date is written 3/14 in the US, which is evocative of the decimal representation of π = 3.14.... Most people are familiar with the decimal representation of π. The media occasionally reports on a new computational tour-de-force that

Did you know that this Friday is Pi Day? How are you planning to commemorate this special day? :) Next year's Pi Day might even be more special than usual, being that it will contain: March 14, 2015 - 9:26:53. And if you realize the coolness of that (3.141592653), you might be
