Faithful followers of this blog have probably figured out by now that my favorite number is 33. Half of my favorite number is 17. Well not exactly, but close. Exactly half is 16 and 1\/2, but half of a number is messy and who wants to deal in fractions anyway. So half of my favorite number has to be either 16 or 17 \u2014 I choose 17 because I like it better.<\/p>\n
Anyhow, today is the 17th of July \u2014 and although it doesn\u2019t get the popularity it deserves, it does have its own holiday. Today is Yellow Pig Day. Many people often confuse Yellow Pig Day with National Pig Day. Don\u2019t be one of those \u2014 they\u2019re completely different. National Pig Day is always on March 1st. Yellow Pig Day is always on July 17th. National Pig Day recognizes and gives thanks to domesticated pigs. Yellow Pig Day is a mathematician\u2019s holiday celebrating yellow pigs \u2014 and \u2014 the number 17!!<\/p>\n
Today, July 17 is not just another ordinary day, just like a yellow pig is not just another ordinary pig. Yellow Pigs have inspired mathematicians for years. Two Princeton math students, Michael Spivak and David C. Kelley actually invented the yellow pig in the early 1960s while working on an assignment to identify unique properties of the number 17. A yellow pig has 17 eyelashes (eight on one eye and nine on the other,) 17 toes and 17 teeth. One story that I\u2019m not sure is true is that the Princeton students carried out many of their intense mental gymnastics and actually invented the yellow pig after only a few pints at the local pub.<\/p>\n
Needless to say, in the years since their invention, Spivak has written a number of mathematics textbooks, where he regularly includes hidden references to yellow pigs, and David Kelly presents an annual mathematics summer school to high school students, where he introduces them to the \u201cCult of the Yellow Pig.\u201d<\/p>\n
So, let\u2019s get back to half my favorite number. Before you read any further, be aware that the fear of the number 17 is called heptadecaphobia. So if after reading this far and you\u2019re still wondering what\u2019s the significance of a yellow pig and the number 17\u2026.. well, if you have to ask, you just won\u2019t understand. <\/p>\n","protected":false},"excerpt":{"rendered":" Faithful followers of this blog have probably figured out by now that my favorite number is 33.
