It’s that time of year again… not Daylight Savings Time, though that has happened. It’s not quite Spring, though we are getting close (if you believe the groundhog).
March 14th (3/14) is Pi Day, the annual celebration of one of the crucial mathematical constants, the ratio of the circumference of a circle to its diameter.
Represented by the Greek letter Π (pronounced pi), the constant has been calculated to over 1 trillion digits beyond its decimal point, according to the official Pi Day website. As an irrational and transcendental number, it will continue infinitely without repetition or pattern.
In 2017, as Pi Day approached, POB received a call from Henry Nass. Nass loves numbers, and he had his own particular offering for surveyors and mapping professionals. He looked at prime numbers and noticed that there are latitude/longitude coordinates that are prime numbers. Where, he asked, are the locations that are represented by the intersection of two such coordinates?
If you don’t care for Pi (and don’t plan on celebrating with a piece of pie), you might enjoy revisiting Nass’s column from 2017 called Are You in a Prime Location? (It goes well with a piece of cake and a glass of milk, I promise.)
