Nailing PiDay
Math enthisiasts always find new ways to be creative. For example, on this math PiDay, Jen Green (one of my WWU students) made my Piday with her PiDay creativity....
In order, they are:
 Pi = C/D (definition of Pi as circumference over diameter)
 3.7,30 (the value of Pi the Babylonians used around 2000 BC)
 4(8/9)^{2} (the value of Pi the Egyptians used around 2000 BC)
 3 (the value of Pi found in the Old Testament which was compiled around 550 BC)
 2(2x(2/3)x(4/3)x...) (the infinite series for Pi developed by John Wallis in 1655 AD)
 3.14 (the approximation of Pi used for PiDay!)
 4 (the value of Pi in Taxicab Geometry);
 16/sqrt(3) (the value found by Edwin Goodwin of Indiana which he attempted to copyright and legislate in the Indiana Pi Bill in 1897)
Here are some closeups of her creative efforts...
Impressed with her creativity, I asked Jen if she would share photos of her Pinails. She responded: "I would be honored to have my nails on your website! ... I'm glad I made your day."
Thanks Jen....!
