pi π day- march 14

  March 14 is celebrating as pi day.

Before starting a question for you why 3.1415...... is known as pi read everything, answer is at the end of this page

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 digits of π.

But

Pi Approximation Day is observed on July 22 (22/7 in the day/month format), since the fraction ​22⁄7 is a common approximation of π, which is accurate to two decimal places and dates from Archimedes.

What is the connection of pie in space?

Pi, also written π, is the Swiss Army knife of numbers. No matter how big or small a circle – from the size of our universe all the way down to an atom or smaller – the ratio of a circle’s circumference (the distance around it) to its diameter (the distance across it) is always equal to pi. Most commonly, pi is used to answer questions about anything circular or spherical, so it comes in handy especially when you’re dealing with space exploration.

Space is full of circular and spherical features, and to explore them, engineers  build spacecraft that make elliptical orbits and guzzle fuel from cylindrical fuel tanks, and measure distances on circular wheels. Beyond measurements and space travel, pi is used to find out what planets are made of and how deep alien oceans are, and to study newly discovered worlds.

some facts of pi   πππππ

• Pi is the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159

• The exact circumference or area of a circle cannot be calculated because there is no true value of Pi

• It cannot be expressed as a fraction because it is an irrational number (an irrational number is a real number that cannot be expressed as a ratio of integers)

• However, a fraction such as 22/7 and other rational numbers are commonly used to approximate Pi

• The decimal value of Pi goes on. It never stops or repeats
• The earliest use of Pi to represent the ratio of a circle's circumference to its diameter was made by mathematician William Jones in his 1706 work called New Introduction to the Mathematics. Leonhard popularised it in the year 1737
• It first appeared in in the phrase '1/2 Periphery' in the discussion of a circle with a radius of one unit
• After Jones, it was not adopted by other mathematicians till 1736. Before that mathematicians sometimes used c or p instead
• Ludolph Van Ceulen spent most of his life calculating the first 36 digits of Pi, which is known as the Ludolphine Number
• In the 19^th century, William Shanks calculated the first 707 digits of Pi by hand, making a mistake after the 527^th place
• The record to calculate Pi has been broken several times. The records are 7,480 digits in 1957; 10,000 digits in 1958; 100,000 digits in 1961, until 1 million digits were reached in 1973
• The greatest mathematician, Albert Einstein was born on Pi Day and the greatest physician, Stephen Hawking died on the same day
• A circle has infinite number of corners calculated with the help of Pi.
  

Now come to our answer why pi

Pi is the Latin name of the sixteenth Greek letter, π. (Mathematic notation borrows from a multitude of alphabets and typefaces.) The first recorded use of π as a mathematical symbol comes from the Welsh mathematician William Jones in a 1706 work called Synopsis Palmariorum Matheseos, in which he abbreviated the Greek περιϕέρεια, (meaning “circumference,” or “periphery”) to its first letter: π.

And one more interesting fact

Let us try to see mirror image of above value hope you got it, yes 

Mirror image of 3.14 gives PIE!
