People are celebrating National Pi Day in the United States and around the world, especially those associated with the field of science, as it represents the mathematical symbol for the constant.

On this national holiday, people enjoy hanging out, preparing and sharing desserts, and creating fruitful and educational memories with their loved ones.

Generally, those who have learned Geometry and mathematics know this symbol. It is represented by a Greek letter π. Recently it has been used on clothing and coffee mugs as a symbol of new style.

It is used to calculate the area and volume of anything containing a circle or sphere with the help of equations. It also helps to size small objects other than large bodies, such as the Earth, Moon and Sun.

According to Manil Suri, a professor of mathematics and statistics at the University of Maryland, Baltimore County, pi helps people understand more about the world, the universe, and how they work.

“It's pretty amazing that there is a constant that is true for all circles. That's what really gets me. Draw any circle and the circumference divided by the diameter will always be the same number. In a way, it's a little creepy,” Suri said in a CBS News report.

“I think it symbolically shows that there are certain laws that the universe follows, and these are mathematics, and for me, as a mathematician, that is key.

Pi appears frequently and often unexpectedly in answers to “thousands and thousands of different math problems,” said Daniel Ullman, a mathematics professor at George Washington University.

“The question really is, 'Isn't it surprising that this number comes up in millions of different environments that seem to have nothing to do with each other?'” he said.

What is Pi Day?

Pi Day is celebrated on March 14 of each year, since the date written corresponds numerically to the first three digits of π.

Coincidentally, in 2015, when the numerical date corresponded to π of up to five digits: 3.1415 was Albert Einstein's birthday.

According CBS NewsPi was known to the Babylonians and ancient Egyptians and was used by Archimedes, an ancient mathematician.

The day was declared a holiday in 1988.

The day was founded by physicist Larry Shaw, who was on staff at the Exploratorium, a science museum in San Francisco.

While making a connection, between March 14 and March 14 during the retreat, he founded the first informal Pi Day and then celebrated it.

Pi Day was recognized after the House of Representatives passed a resolution on March 12, 2009, designating March 14 as National Pi Day.

The Pi Day website suggests celebrating the day by eating and baking cakes, including observing the mathematical principles of pi using a cake as a themed activity.
