Pi Day at CofI is March 14 at 1:59 p.m. (3.14159 get it?)

2007. 03. 12.

CALDWELL – Albertson College of Idaho (ACI) will celebrate Pi Day for the fourth year in a row with several festivities on March 14 – the approximate calendar equivalent (3.14) of the irrational number, which is the ratio of the circumference of a circle and its diameter.

The CofI math club, which hosts Pi Day every year, calls it a "celebration of irrationality." Activities include:

• Pi recitation – Memorization and recitation of pi. The current record is more than 200 digits.
• Pi walk – Participants walk to the music of "American Pie." When the music stops, a fraction of pi is randomly chosen and if the person standing on that number can correctly convert the radian measure to degrees, then he/she wins a pie.
• Pi chain – Since 2004, Pi Day participants have worked on the Pi chain, which is loops of colored paper. Each color represents a digit. New links are added to the same Pi chain every year and it's currently 429 digits long.

Slices of pie will be available for purchase for $1 each.

In keeping with the theme, Pi Day festivities begin in Boone Science Hall at about 1:59 p.m. (pi begins 3.14159…) and is open to the public.
