Why is pi calculated even if it is not enough? Scientists believe that it contains the secrets of the universe, and there is a secret in it

As we all know, PI is a common mathematical constant in mathematics and physics. It is represented by the Greek letter π, which is an irrational number, that is, an infinite non cyclic decimal. We use π to calculate the circumference, area and volume of a circle. But do you know how Pi is calculated? Why do people say it is closely related to the mysteries of the universe?

The development of π

Egyptians seem to be the first to know PI, because some scholars found that the ratio of circumference and height of Khufu pyramid is equal to twice of PI, just equal to the ratio of circumference and radius of circle.

From 1900 B.C. to 1600 B.C., it was recorded on a stone plaque in Babylon that pi = 25 / 8 = 3.125.

From 287 BC to 212 BC, Archimedes, an ancient Greek mathematician, gave an estimate of PI, which was between 3.1408 and 3.1428.

Around 480 A.D., Zu Chongzhi, a famous mathematician in the northern and Southern Dynasties of China, first accurate the “Pi” to seven decimal places, and gave an approximate value between 3.1415926 and 3.1415927. His calculation has a very important influence on later generations.

It was not until the beginning of the 15th century that the Arabic mathematician al Qassim obtained 17 precise decimal values of PI, which broke the record of Zu Chongzhi and kept for nearly a thousand years.

In 1610, Rudolph spent all his life in German mathematics, calculating 35 digits after the decimal, so the number is called “Rudolph number”.

With the continuous development of science and technology, for today’s us, to calculate the PI, as long as we move our fingers and tap a few times on the computer, we can get the value we want. So far, Japan’s Kondo Maoli has spent about a year calculating pi to 10 trillion decimal places through his own home computer, setting a Guinness world record.

What’s the secret of Pi?

And no matter how many places after the decimal, do you also find that the PI is an infinite non circular decimal, we can never calculate it, so it also shows that there is no real circle in the world.

For example, Archimedes’s method of calculation is that a fixed circle is cut into polygons. As the edges of polygons are divided wirelessly, they become closer to the circle. However, no matter how many edges there are, they are always polygons and can’t be as smooth as circles, which is the reason why the PI can’t be calculated completely.

If the PI is fully calculated, the whole mathematical world may collapse, and great things will happen in the world.

Some scientists believe that the appearance of PI may be related to the universe. PI is an infinite non cyclic decimal. The number after the decimal point appears randomly, which is very similar to the celestial bodies in the universe. They have no boundaries and are endless.

Some scientists believe that although there is no law to follow in PI, we can still find some “coincidences” in it. For example, the date of someone’s birth, or any article you’re reading now, after converting them into digital coding, you will find them in the infinite number of PI.

PI is so mysterious, although it is not enough, but we still have to try hard, this is the spirit of seeking knowledge, maybe one day, we can know the ultimate secret of the universe!
