The first Pi Day celebration was organized by physicist Larry Shaw at the San Francisco Exploratorium in 1988 (and just FYI: the 2015 Pi Day was called the "Pi Day of the Century" because its date in the day-month-year format was 3-14-15, which gives the first four digits of pi). However, the concept of pi, the ratio of a circle's circumference to its diameter, has ancient roots that date back to the Babylonians and Egyptians, around 2000 BCE and 1650 BCE, respectively. The first rigorous calculation of pi, using a geometrical approach with polygons, was devised by the Greek mathematician Archimedes around 250 BCE. | For info on the Pi skyline shown above, click HERE. |
Nope.
However, Dickinson did use the word “circumference” in seventeen poems – or sixteen poems depending upon which version of “Two butterflies went out at Noon” you read. The 1863 version does NOT include the word “circumference”; her version from 1878 does.
“Cap-a-pie” appears in the opening lines to “Sic transit gloria mundi” (“thus passes the glory of the world”). The complete poem (Dickinson’s longest) is HERE.
