Various Aspect of Pi by Mike & Carol Werner
Don’t confuse Pi with pie!
Pi represents the ratio of a circle’s circumference to its diameter, always equaling 3.14159265359. The digits 3.14 and the symbol π are associated with the famous mathematical number.
In 1988 a physicist named Larry Shaw, who worked at The Exploratorium science museum in San Francisco, organized the first official celebration of the number by declaring “Pi Day” on 3/14. The staff and public walked around a circle and then consumed fruit pies. The U.S. House of Representatives officially recognized March 14 as “Pi Day” and the month was designated as “Pi Month” (in addition to St. Patrick’s Day celebrations).
Pi Day 2015 marked a very special occasion. It was the first occasion in human civilization when all the digits of Pi appeared in our modern calendar and time systems. That date was 3/14/15, which matched the first 5 digits 3.1415. At 9:26am, on the 53rd second, the next 5 digits of the figure (92653) were represented. If you considered milliseconds, then 59 equaled the remaining two digits.
In honor of Pi Day, we curated a small collection of posters and shirts showcasing Pi.
