Toggle**What is Pi?**

Pi is a mathematical constant representing the **ratio of a circle’s circumference to its diameter**. In simpler terms, pi tells you how much bigger the circumference of a circle is compared to its diameter, regardless of the circle’s size.

**Why March 14th?**

The date **March 14th (3/14)** reflects the first three significant digits of pi, making it a fun and easy way to remember the day.

**History of Pi Day:**

Pi was founded in **1988** by physicist **Larry Shaw** at the San Francisco Exploratorium, a science museum. It started as a way to celebrate math in a fun and relatable way.

#### Many fun activities surround Pi Day, including:

**Eating pie:**This playful connection comes from the word “pi” sounding similar to “pie”.**Reciting pi digits:**Enthusiasts compete to see who can recite the most decimal places of pi from memory.**Holding educational events:**Schools and museums often use Pi Day to organize activities and workshops to promote the importance of mathematics.**Sharing pie-related puns and jokes:**The internet is usually flooded with memes and jokes related to pi and pies on this day.

**Additional Facts:**

- Pi is an
**irrational number**, meaning it cannot be expressed as a simple fraction and its decimal representation never ends or repeats. - Pi has been calculated to trillions of decimal places, but its exact value remains unknown.
**UNESCO (United Nations Educational, Scientific and Cultural Organization) declared March 14th as the International Day of Mathematics**in 2019, further reinforcing Pi Day’s role in raising awareness about the value of mathematics.

Whether you’re a math enthusiast or simply enjoy a good pun, Pi Day offers a unique opportunity to celebrate the fascinating world of mathematics and enjoy a slice of pie (or two)!

### What is pi 3.14 day?

Pi Day, also known as Pi 3.14 Day, is an annual celebration of the mathematical constant pi (π). Pi Day was founded in 1988 by Larry Shaw, an employee at the San Francisco Exploratorium, a science museum. It’s a lighthearted way to celebrate math and all things circular!

### Pi day is celebrated on whose birthday?

Pi Day is celebrated on the birthday of **Albert Einstein**. It falls on **March 14th** every year. This date was chosen specifically because:

**The month/day format (3/14)**corresponds to the first three digits of pi (3.14…).**March 14th happens to be the birthday of Albert Einstein**, a renowned physicist who made significant contributions to mathematics and science.

While there’s no inherent connection between Einstein and Pi, the date cleverly combines these two aspects, making it a memorable day to celebrate the mathematical constant.
