(1) THE HISTORY OF π DAY

The first National Pi Day was observed in 1988 by the American artist and physicist Larry Shaw in San Francisco by marching in circles with colleagues and snacking on different kinds of pie.

In 2009, the United States House of Representatives officially designated March 14th as National Pi Day and identified Shaw as the founder of the famous mathematical holiday.

(2) WHAT IS π ?

Pi (π) is the ratio of any circle’s circumference to its diameter.

The value of this ratio is approximately 3.14 and, yes, this relationship applies to any circle big or small.

(3) WHERE DID THE PI(π) SYMBOL COME FROM?

The π symbol that we use in math to represent pi was first used by the Swiss mathematician, physicist, and astronomer Leonard Euler in the year 1737.

Before Euler popularized using the greek symbol π to represent the ratio of a circle’s circumference to its diameter, the value was known as Archimedes' constant.

(4) HOW LONG IS THE VALUE OF PI(π)?

The value 3.14 is used as an approximation for Pi since it is an irrational number that continues on and on forever, hence the “…”

π =3.1415926535897932384626433832795028841971693…

The current world record for memorizing the digits of pi is 67,890 consecutive digits set by Lu Chao in 2005.

Mathematicians estimate that it would take 133 years for a person to recite the 6.4 billion known digits of Pi without stopping!

(5) WHAT IS THE EARLIEST REFERENCE TO PI(π)?

Even though the greek symbol π wasn’t adopted until the 1700s, the earliest references to the constant ratio between any circle’s circumference and diameter occurred in Ancient Egypt around 1650 BCE.

Pretty cool, right?

(6) WHAT IS THE COMMON OCCURRING NUMBER IN THE FIRST 100,000 DECIMAL PLACES OF PI(π) ?


The most common number in the first 100,000 decimal places of pi is the number 1, which occurs over 10,000 times!

(7) ARE THERE ANY FAMOUS PI DAY BIRTHDAYS?
There are several famous people born on March 14th, Pi Day, including Albert Einstein, NBA All-Star Steph Curry, Actors Billy Crystal and Michael Caine, and Olympic Gold Medalist Simone Biles.

( WHO DISCOVERED THE MOST NUMBER OF DIGITS OF Pi?
Mathematician and computer scientist Fabrice Bellard calculated 2.7 trillion decimal places of pi using just a typical desktop computer in 2010.

That’s a lot of digits!

(9) HOW LONG IS PI?

As mentioned earlier, Pi is an irrational number and is thus infinite. In fact, it would take 12 billion digits of pi typed out using a normal-sized font to connect New York City and Kansas City.

And since pi goes on forever, it has enough digits to wrap around the entire world an infinite number of times!

(10) IS PI PRESENT IN NATURE?

You bet!

Pi can be used to measure circular natural events ranging from water ripples that emanate from a single point to finding the spherical volume of the entire universe (which can be done using only the first 39 digits of pi!)

(11) BONU$! WHAT ABOUT PIE DAY?

Even though Pi Day is a mathematical holiday, it’s hard to ignore the homophone that is PIE DAY.

Many people celebrate Pi day by eating pie and other circular-shaped foods.

In fact, many pizzerias and bakeries offer special Pi Day deals and discounts on March 14th each year.

And as for pies, Apple Pie is considered the most preferred flavor of pie amongst Americans, with Pumpkin Pie coming in second, and Pecan Pie in third.

...and fish pie in nigeria.
HAPPY PIE DAY EVERYONE.
