Pi Day is an annual celebration of the mathematical constant π (pi).
Pi Day is observed on March 14
(3/14 in the month/day format) since 3, 1, and 4 are the first three
significant figures of π. It was founded in 1988 by Larry Shaw, an
employee of the San Francisco, California science museum, the
Exploratorium. Celebrations often involve eating pie or holding pi
recitation competitions. In 2009, the United States House of
Representatives supported the designation of Pi Day. UNESCO's 40th
General Conference designated Pi Day as the International Day of
Mathematics in November 2019.
March 14 marks Pi Day, an annual celebration of the mathematical sign
pi. Founded in 1988 by physicist Larry Shaw, March 14 was selected
because the numerical date (3.14) represents the first three digits of
pi.
And why do we celebrate it?
Every year on March 14, the world celebrates Pi Day to recognise the
mathematical constant, Pi. It defines as the ratio of a circle's
circumference to its diameter and the value for Pi is 3.14.diameter and
its value is 3.14.
Why is 3.14 called pi?
And how did it get its name "pi"?
It was first called "pi" in 1706 by (the Welsh mathematician) William
Jones, because pi is the first letter in the Greek word perimitros,
which means "perimeter."
Who was born on Pi Day?
Albert Einstein's birthday is on March 14 — 3/14 — which is celebrated
as Pi Day.
