Pi Facts

Hey guys! Today I will introduce some interesting facts about Pi (𝝅), an irrational number defined as the ratio of the circumference of a circle to its diameter.

1. 39 decimal places of pi are enough to compute the circumference of a circle the size of the known universe with an error no greater than the radius of a hydrogen atom.
2. “Pi Day” is celebrated on March 14, and the official celebration begins at 1:59 PM, to form 3.14159 when written together with the date.
3. The symbol for pi (π) has been used regularly in its mathematical sense only for the past 250 years.
4. Egyptologists and followers of mysticism have been fascinated for centuries by the fact that the Great Pyramid at Giza seems to approximate pi. The vertical height of the pyramid has the same relationship to the perimeter of its base as the radius of a circle has to its circumference.
5. The first 144 digits of pi add up to 666 (which many scholars say is “the mark of the Beast”). And 144 = (6+6) x (6+6).
6. Pi is also referred to as the “circular constant,” “Archimedes’ constant,” or “Ludolph’s number.”
7. Albert Einstein was born on Pi Day (3/14/1879) in Ulm Wurttemberg, Germany.

I apologize for not being able to post this before Pi Day, but Pi facts are always good to know! I hope you all found these facts interesting as much as I did! Have a great rest of the day!
