Did Neolithic humans build this structure to celebrate Pi Day? Not likely: Pi Day is a relatively recent phenomenon
-invented by
physicist in 1988 and designated by Congress
national holiday in
2009
But its already almost certainly the most popular holiday celebrating
mathematical constant: While Pi Day is
young tradition, the number Tr (pi) itself has been
fascination since antiquity;
when it was first calculated as the ratio of
circle's circumference to its diameter
You probably know that March 14 was chosen for Pi Day since the date expressed numerically (in monthidate format) matches the numbers first digits_
3.14. Aside from eating pie t0 celebrate
some
people go to great lengths to memorize digits that go way beyond 3.141592.
which earns them
bragging rights in some ,
um, circles: The world record is a staggering 70,000 digits after the decimal
point_the remarkable feat was achieved by 21-year-old student Rajveer Meena in 2015.

tools and is older than
Egypt's pyramids_
Theories abound; of course
but could TT have been involved?
