Pi – 3/14 @ 1:59:26 AM

Pi is a number that has enamored people for hundreds of years.  While it is much older and was known far longer, it recently (within the last 250-ish years) became super popular.  Here are some facts to think about on Pi Day:

  • Pi as a calculation has been known for over four-thousand years.
  • Babylonians and Egyptians used it long ago, but had miscalculated it to between 3.104 and 3.1604.
  • The symbol for Pi has only been used for a couple hundred years.  Before that, it was a pain in the butt to say because you had to actually describe the function that resulted in the value.
  • Amy Farrah Fowler’s apartment  on The Big Bang Theory is 314.
  • One of the best computational tests used for stress testing hardware is the calculation of Pi.
  • Other names for Pi are: Archimede’s Constant, Circular constant, and Ludolph’s Number.
  • Ludolph van Ceulen spent most of his adult life calculating the first thirty-six digits of Pi.
  • Albert Einstein was born on Pi Day.  He would be 138 years old today.
  • Eugene Cernan, the last man to set foot on the Moon, was born on Pi Day.
  • Because we have no exact value for Pi, it is impossible to measure the exact circumference of a circle.
  • Because a corner is defined as a change in angle, a circle is not “corner-less.”  Circles actually have an infinite number of corners.

Now, go celebrate Pi Day and have a slice of the good ol’ Apple 3.14.
