Applied math professor Ingrid Daubechies first learned about pi as a young child, when her father told her to go around the house and measure the circumference and diameter of every circle she could find.

Great article. However, it is most likely that the party celebrating Pi Day held by the undergraduate math club was held at 1:59 pm (rather than 2 PM) since the time then was 3.14159 (March 14th at 1:59); showing pi to the first 5 decimals.

Nice article. One minor mistake: The "calculation" from 1 Kings 7:23 results in a value of pi=3 to one significant digit. This is neither a truncation nor an inaccuracy. Since the original numbers (30 and 10) had only one significant digit, so does the answer to the calculation. It's a round number, or an approximation, not a mistake, inaccuracy, or truncation.

cool Pi Day site http://www.PiDayInternational.org Has illustrated history of Pi. You can join the World Federation of Pi. Also has Pi Diner - with a "Pi-O-Matic" which dispenses pi - MILLIONS of digits of pi. We did a dorm activity watching Pi Drop for Pi Day at http://mathematicianspictures.com/PI/PI-DAY.htm .
