Your One Stop Shop for Pi Day!

Did you know that today is National Pi Day? And not just that, it’s a very special Pi Day because you won’t get to see one like it until March 14, 2115! Today, Pi Day 2015, will be the only Pi Day for the next 100 years that reflects the first five numbers in that well-loved irrational number, pi, which is 3.1415 (March 14, 2015).

In light of this Pi Day being such a special one, we’ve decided to bring together a bunch of Pi/e related content, such as recipes, crafts, facts, and humor, just for your enjoyment! 

PI FACTS:

  • In the Greek alphabet, π (piwas) is the sixteenth letter. In the English alphabet, p is also the sixteenth letter. Sometimes, people get pie on their 16th birthday, but that’s not important. 
  • In 2005, Chao Lu of China recited Pi  from memory to 67,890 places. He holds the Guiness World Record for Pi knowledge. I would not want to eat 67,890 pies to become the pie champion.
  • William Shanks (1812-1882) worked for years by hand to find the first 707 digits of pi. Unfortunately, he made a mistake after the 527th place and, consequently, the following digits were all wrong. That means he got 527 numbers right and trillions after wrong, kind of like weather reports.
  • In 2002, a Japanese scientist found 1.24 trillion digits of pi using a powerful computer called the Hitachi SR 8000, breaking all previous records. Sadly, Hitachi SR 8000 was forever typecast as a pi solving computer, and nobody ever used it again for solitaire and cat videos.
  • One of the earliest known records of pi was written by an Egyptian scribe named Ahmes (c. 1650 B.C.) on what is now known as the Rhind Papyrus. He was off by less than 1% of the modern approximation of pi (3.141592). Ask to why he was solving pi and not doing his actual job as a scribe, we will never know.
  • Albert Einstein was born on Pi Day (3/14/1879) in Ulm Wurttemberg, Germany. The time he was born is all relative. Happy Birthday Einstein!
  • DID YOU KNOW? If you hold 3.14 up to a mirror it spells PI.E
  • Pi has 6.4 billion known digits that would take approximately 133 years to recite without stopping. I hope someone hasn’t actually tried this.
  • In the Star Trek episode, “Wolf  in the Fold”, Spock commands an evil super computer “to compute to the last digit the value of pi” (which, knowing pi, is highly illogical).

CIRCLE FACTS:

  • In situations where there are no navigational clues – such as a snowstorm or thick fog – humans always end up going around in circles. Research carried out in 2009 by the Max Planck Institute for Biological Cybernetics in Tübingen had volunteers set down in a particularly empty bit of the Sahara or the dense, flat Bienwald Forest in south-west Germany, and tracked them using GPS. When the sun or moon was out, they were perfectly capable of walking in a straight line. When it wasn’t, they started to walk in circles, crossing their own path several times: the average diameter of the circle they walked was only 66ft (20m). It suggested that we have no instinctive sense of direction. Never mention this to your husband until after the family vacation is over.

National Pi Day wouldn’t be complete without pie! Here are a few of our favorite Pie Recipes:
