Of course, we have readers who, because of their profession or department, are much more familiar with the number of pi. However, the rest pi number for many; which is accepted as 3 in math operations, has no end, in which we can even find our Turkish identity number. It’s a mathematical term. The fact that it has been heard at least by uninformed people shows the importance of the number pi.

Agree; what is the number of pi, how to find it, How many digits, when was it found? Although we kind of know what it is, many people don’t realize how important a constant value of pi is.

What is the pi number?

PI number; the circumference of a circle to the diameter of that circle It is a mathematical constant that expresses the ratio. Greek meaning environment περίμετρον first letter of the word is displayed with . Pi is an irrational number. The decimal does not end as an integer (¼ = 0.25) or repeats forever (1.66666…). It is also called Archimedes’ constant or Ludolph’s number.

What exactly is the trillion digit pi number?

Regardless of size, if you divide the circumference of a circle by the diameter of the same circle, you get about 3.14. This is the number pi. We say approximate because pi has quite a few numbers. Finally, its 31.4 trillion digits were calculated by Google employee Emma Haruka Iwao in 2019. Iwao currently holds the record.

You can also try: how do you find the pi number?

Draw a circle using a compass to get the correct reading. Take a piece of string and wrap it around the circle. Open the rope and measure its length. Find the diameter of the circle you created by measuring the distance from any point on the circle from the center to the point on the other side. Note that the diameter of the circle is twice the radius.

Divide the circumference of the resulting circle by the diameter of the circle. Regardless of the width of the circle if you judge the value you get will be about 3.14. You can try the measurement endlessly, down to the trillionth digits of pi. This magical mathematical constant has been used for thousands of years.

Thousands of years of history of pi numbers:

Let’s go back thousands of years, to 1900 BC, to the Babylonian Empire. Babylonians, calculated by squaring a circle They found that the pi number was 3,125. It is quite close to today’s accepted value.

An Egyptian papyrus from 1650 BC. shows that the Egyptians calculated pi as 3.1605. In 287 BC Using the Pythagorean theorem, Archimedes cannot find an exact value for the number pi, but determines that it has a value between 3.1/7 and 3.10/71.

In the following years, the number of pi; It was calculated as 3.14166 by Claudios Ptolemy, 355/113 by the Chinese Zu Chongzhi, 3.1415926 by the Italian Lazzarini and 3.141818 by Fibonacci. After the 18th century by Greek mathematicians The pi number, whose symbol and value are determined, is still calculated by accepting the value of 3.14 as constant.

Why is the pi number so important?

Everyone has dealt with this number for thousands of years and the Google employee has quit the job. Calculated trillions of digits artificial intelligence systems are even being developed to calculate the exact value. Well, why did mankind give up everything and deal with calculating the number of pi, why is it so important?

First of all, we have to say that this song sounds like magic. In an unimaginably large apartment, a small coin You get the same ratio if you divide the circumference by the diameter. As if that weren’t enough, you can find the area of ​​the circle by multiplying the number of pi by the square of the circle’s radius. In other words, if there is a circle in the work, the pi number must be included in the process.

So, why are the numbers calculated? Think of the circle you just made with the rope. Divide that rope into 3 equal parts You cannot make the same circle. Even if you divide it into 3.14 equal parts, you can’t do it. Those fractures certainly cause errors, sometimes even microns. But one day we will probably be able to make pieces that literally fit together “exactly” if the pi number is calculated exactly, possibly with the help of artificial intelligence.

What we can do with the pieces that “just” fit together is left to the imagination of scientists. With nanotechnology mistakes that we can’t even imagine can be ended before they happen. With nanosurgery Cancer, still in the form of a cell, can end before it even starts. With the real number of pi, all this can become possible.

We answered questions such as what is the pi number, how is it found, what is its role in the historical process, and we explained the notable points. The magic constant of the mathematical world is pi It will continue to surprise us when it is used and the steps are calculated.
