What is PI?

---

It is very likely that at some point, whether at school or elsewhere, you have encountered "Pi", mathematical terms equivalent to 3,142 and are most represented by the Greek word "π."

For many people, especially those who are not familiar with mathematics, or stop learning many years ago, PI seems meaningless, unnecessary, and confusing.

Let's look deeper to PI, where it comes from, and why it is often used in mathematical calculations.

What does it mean?

First of all, consider what Pi really means and why it is used in mathematics.

Numbers are equivalent to PI, 3,142 to three decimal places, which are the number you get when circumference is any circle divided by its diameter.

This will be the case regardless of the size of the circle you are using.

Therefore, PI can be used to help with a variety of calculations, including working with the length of the diameter of a circle or perimeter length of the circumference.

Although PI is 3,142 when rounded up to three decimal places, it doesn't stop there.

PI, or circumference rate of the circle on its diameter, is not a ratios that are not a periodic decimal example.

Where does PI come from?

'

A significant period of time for PI research has been used to increase the accuracy of PI and its digits.

Historians and mathematicians believe that PI is known for 2000 years B.C., and Egyptians and Babylon people know about it and the use of it.

'

Advances in technological and mathematical studies are in the 21st century, more than 6 billion digits of Pi have been known.

Anniversary PI worldwide!

PI is quite special in the world of science, math and number.

With billions of digits remembered, it is not surprising that PI has become a challenge for many people trying to beat a world record.

Rajveer Meena, from India, held a world record in 2015, read 70,000 digits.

Lu Chao, from China, formerly held a record since 2005-2015 after reading 67,890 digits of PI.

He defeated the world record holder in 1989, Hideaki Tomoyori from Japan, who read 40,000 digits.

Outside the Mathematical Building and Berlin Technical University, one of the most notable technology universities in the world, there is a mosaic formation of parts of the concrete path and describing the PI symbol.

Ludolph van Ceulen (1540-1610), a Dutch Mathematician, spent most of life to try to calculate PI's digits.

In 1594, he published a book containing a total of 20 digits of PI.

After that, he came out 15 more digits, up to 35 digits.

Van Ceulen is buried in Leiden, where PI with its 35 known digits are engraved on their tombstones.

William Jones (1675-1749), a Welsh mathematician, is the author of some books and works, including mathematical beginners.

In a 1706 publication served for beginners, he used PI to explain the perimeter of a circle on its diameter.

Leonhard Euler (1707-1783), a Swiss Mathematical Factory, physicist and engineer, often recognized as promoting the use of PI in the mathematical world.

He introduced other symbols for functions and logarithms, and used Pi in his two books, helping to disseminate its use.

Isaac Newton (1642-1727), an English mathematician, also plays an important role in PI development, especially on the progress in accuracy and number of known digits.

In 1666, Isaac Newton used a series of arcsin, or inverse tricks, to calculate the first 15 digits of PI.

This was done after discovering calculations of Isaac Newton and German mathematician Gottfried Wilhelm Leibniz.

Future of PI.

Although people accept that enough Pi's digits are known to ensure the most accurate calculation possible, who knows what the future keeps and how many digits of PI can be detected in one
