NATIONAL PI DAY

National Pi Day on March 14th recognizes the mathematical constant π. Also known as pi, the first three and most recognized digits are 3.14. The day is celebrated by pi enthusiasts and pie lovers alike!

#NationalPiDay

Pi is the ratio between the circumference of a circle and its diameter. While the idea of pi has been known for nearly 4000 years, accurately calculating it has been something of slightly more recent mathematical development. By 2000 BC, the Egyptians and Babylonians accurately used the constant to build. Mathematicians such as Archimedes, Fibonacci, François Viète, Adriaan van Roomen, and Gottfried Wilhelm Leibniz all calculated pi by various methods. However, in 1706, Welsh mathematician William Jones introduced the Greek letter π to represent the ratio of a circle’s circumference; pi.

HOW TO OBSERVE NATIONAL PI DAY

Celebrate the day with a slice of a pie cut using the mathematical constant of pi.

Host a pie-eating contest.

Discuss the significance of the number π.

Watch the Life of Pi.

Look for 3.14 in unexpected places. For example, prices, street numbers, or license plates.

Finding 3.14 deals in as many versions of π as possible. For example

Think pizza Pi as much as dessert kind of deals on this day!

Get punny Geeky Greek Pi-inspired t-shirts deals.

I used to know Pi out to several digits. Now I'm lucky if I can remember there's a period after the three...

The number represented by ‘pi’ is a mathematical constant that is the ratio of a circle’s circumference to its diameter, approximately equal to 3.14159.

It is an irrational number, meaning that it cannot be expressed exactly as a ratio of two integers, although fractions such as ‘22/7’ are commonly used to approximate it.

Consequently, its decimal representation never ends, nor enters a permanently repeating pattern. It is a transcendental number, meaning that it cannot be a solution of an equation involving only sums, products, powers, and integers.

I’m here at my tutoring center and even this year one of our tutor leaders brought a big pie. We always had a bunch of pies pre-scamdemic. Not many in-person tutors or students now so don’t need much. Sad in a way. The hysteria made a huge void here at college. Don’t need many pies.

If you draw a circle with a diameter of 1”, then you have drawn a circle with a circumference of pi, meaning that you have created a line with an irrational length ...

The circle's edge, an endless line
A mystery that we can't define
A number that goes on and on
Pi, irrational and never done

From Archimedes to modern day
We've tried to find pi's final say
But still it dances out of sight
In never-ending decimal flight

So let us marvel and embrace
This enigma of a number's grace
And celebrate the mystery
Of pi, that never will be free.

True Story:

Our phone number used to be one digit off from the number of a convenience store a mile or so from where we used to live.

We used to get phone calls all the time, meant for the store or its employees, even waking us up in the middle of the night.

One particular woman seemed to call every night about 2 am wanting to speak to her husband or boyfriend that was on duty there at that time.

After about a month of this, I finally got tired of being woke up at 2am.

When the phone rang, and she asked for her man, I told her he just left.

“Left where?” she said.

“I don’t know, he just left with some woman I didn’t know.”

CLICK!

Never got another wake up call at 2am.....................
