Quotation of the Moment: Pi Day

"The sea was then cast; it was made with a circular rim, and measured ten cubits across, five in height, and thirty in circumference"
I Kings 7:23
This refers to a large circular tank at the Temple of Solomon that held about 12,000 gallons of water.

Hat tip: History of Pi by Petr Beckmann


  1. So, pi=3 to a first order engineering approximation.

    I can live with that. :-)

  2. If you look at Beckman's book, most ancient societies had a closer approximation, usually on the order of 3 1/7

  3. Eric:

    When I need to get a close approximation of a circumference or circular area and I don't have my slide rule handy, I too use 22/7 for the mental arithmetic. Gets to within about 0.04%.
