On March 14, the nerdier side of humanity celebrates Pi Day, a holiday that “commemorates the irrational, transcendent, and never-ending ratio that helps describe circles of all sizes.” Pi is the ...

A researcher at the National Energy Research Scientific Computing Center has taken a major step toward answering the age-old question of whether the digits of pi and other math constants are "random" ...

It’s Pi Day, the nerdiest of holidays because it’s all about a mathematical constant that represents the ratio of a circle’s circumference to its diameter (yes ...

Imagine a cup of tea. Wrap a piece of string around the circumference of the cup, and measure the length of the string. Then, lay your spoon on top of the cup, making sure it lies across the center of ...

Swiss researchers at the University of Applied Sciences Graubünden this week claimed a new world record for calculating the number of digits of pi—a staggering 62.8 trillion figures. By my estimate, ...

Swiss researchers said on Monday they had calculated the mathematical constant pi to a new world-record level of exactitude. The constant π is represented in this mosaic outside the Mathematics ...

Researchers at the Swiss university Fachhochschule Graubünden claim that they’ve broken the world record for the most calculated digits of pi, a mathematical constant that describes the ratio of a ...

Memorizing four digits worth of pi is no piece of cake. McDonell Central Catholic High School math teacher Tony Reiter’s Pi Day contest, normally held on March 14 each year, yielded a student going ...
