[Surnetkids] Pi Approximation Day

Dear Reader,

Every summer, as July heats up, I remember the night when when Neil Armstrong and Buzz Aldrin walked on the moon: July 20, 1969. Here are some website resources for those that want to explore Apollo 11.

See ya on the Net,

Pi is the ratio of the circumference of a circle to its diameter. Regardless of the size of the circle, pi is always the same irrational number: approximately 3.14 or 22 divided by 7. Because July 22 is 22/7 in the date format used by most of the world, it is celebrated as Pi Approximation Day. March 14 (3.14 in a US month-first date format) is celebrated as Pi Day primarily in the US.

Math Forum: Ask Dr. Math: About Pi

“For the sake of usefulness people often need to approximate Pi. For many purposes you can use 3.14159, which is really pretty good, but if you want a better approximation you can use a computer to get it.” Dr. Math answers basic questions about Pi and includes an extensive list of links to other Pi-related questions and answers from the Math Forum archive. The little red star icons indicate “particularly interesting answers or good places to begin browsing.”

PBS: Nova: Approximating Pi

“Around 250 B.C., the Greek mathematician Archimedes calculated the ratio of a circle’s circumference to its diameter. A precise determination of Pi, as we know this ratio today, had long been of interest to the ancient Greeks, who strove for precise mathematical proportions in their architecture, music, and other art forms.”

Pi Land

Eve Andersson is a Google engineer with a soft spot for Pi. Her homage to Pi includes a Pi Trivia Game consisting of twenty-five randomly chosen questions (“Finally this is your chance to pay tribute to the magnificent transcendental number that we have all grown to love!) and a Pi Trainer to test your memory of the digits of Pi. Under Aesthetics, she publishes a few Pi poems and a small photo gallery. Nerd Stuff includes the digits themselves and graphs of digit frequency.
