What is Pi? Why do scientists continue to calculate to 30 trillion?

I studied history in junior high school and knew pi, which was written by Zu Chongzhi at the beginning. At that time, he accurate pi to the 7th decimal place, which was also the first such accurate pi in history. And now, with the birth of supercomputers, humans have calculated pi to the trillion-level position.

If this number is arranged according to its normal size, it can return to the earth hundreds of times. But why are scientists still persistently calculating pi? <>

We all know that pi has a lot to do with a circle, and he can easily calculate the area of the circle and the volume of the sphere by knowing the radius of the circle. In the research of scientists, it has been found that most of the celestial bodies in the universe exist in a spherical shape. Why do so many celestial bodies in the universe exist according to this shape, can't a rectangular rectangle?

Obviously, the existence of a sphere is a special state that maintains a balance between all things in the universe. This is why countless scientists are fascinated by calculating the true number of pi. <>

Anyone who has studied mathematics knows that pi is an irrational number, and according to the way mathematics calculates, there is no way to calculate the last number. But on this point he is in conflict with our universe, because we all know that the universe has a certain boundary, no matter how big it is. Although the current universe is still expanding outward at a relatively fast rate, scientists all know that when the energy generated by the universe tends to balance, the universe will stop expanding.

Then according to the revolution between the planets, through a special equation, and then using pi, we can calculate the diameter of the universe in which we live. This will help mankind explore the universe farther away, and it can be used to calculate the laws of some celestial bodies. But we can't calculate the last digit of the circumference point yet, but I think that with the development of technology, mankind's understanding of the universe has deepened.

The cone rate may really have an end point in the end.

Pi has been calculated to trillions, and scientists are still so persistent, why?

Pi, with the help of supercomputers, was easily calculated to billions of bits, and now it is said that pi has been calculated in trillions of bits. At the earliest time, everyone knew pi when they were in elementary schoolIt is equal to between, which is something that has been studied in ancient mathematics in our country, when there were no supercomputers. <>

Now there are computers, especially supercomputers with strong computing power made by various countries, and its computing power is very strong, to what extent? Then it has to have a representative thing. Therefore, all countries are calculating pi, and pi calculation has two most important functions, one is to test how strong the computer is, and the other is related to the concept of constants in mathematics.

Theoretically it is irrational because it is an infinite non-cyclic decimal number, and people have calculated so many digits and still come to this conclusion. <>

Nowadays, the computer posture leakage made in various countries can be said to be superior in performance, and one of the indicators to measure its performance is to calculate the number of digits in the back of the pi in a long time. As long as you are willing to spend time, this number of digits cannot actually become an absolute standard, because if you are willing to spend a year and want to break through this trillion digits, it is not that you can't break this record, and it won't stay for a long time. It depends on whether you are willing to do itThe number of digits in pi calculated within a certain period of time means that the supercomputer has more computing power.

There is also the stability of the mathematical edifice, the definition of rational and irrational numbers. This is a geometric issue. Theoretically pi it is an infinite non-cyclic decimal and it is not a rational number.

But if one day, with the help of supercomputers, pi is really calculated, then the grassroots of the mathematical edifice may start to be re-deducted, and now everyone thinks that many of the right things may be changed in the future.

Because science is very rigorous, we may need an approximate data when calculating the circumference of a circle, but Ying Qinghui needs to be more precise when he uses the top scientific field, so he has to calculate more later.

Pi is an indication of the diameter and circumference of a circle. Calculating pi can reflect the scientific level of a country to a certain extent.

It is to regret discovering the law behind the positive number of pi, and also to better approach this value, which is conducive to the calculation after the silver search, and also for the sake of science.

Because every scientist is studying and developing an obsessive attitude, some mathematicians are very passionate about mathematical calculations and mathematical knowledge.

In general, most students are able to understand the use of pi after a series of studies. To further reduce the calculation, most schools will require students to take the last two digits of pi, which one simply needs to substitute into the formula. Although most students don't actively memorize a long list of decimal numbers, it doesn't mean that scientists have given up calculating pi.

Nowadays, scientists have calculated pi to trillions of decimal places, and netizens have praised the research status of scientists.

Over time, more and more research projects have been established, and many research groups have used a variety of materials and environments to complete research projects. Some professors in the research group will lead the students to complete the project research step by step, and they will always maintain a very serious attitude and research enthusiasm when researching the research project. Scientists are always relieved when a research project achieves phased results.

When we are very passionate about a certain field or a certain thing, we will always try to understand the knowledge of a certain field. Scientists have been immersed in research for a long time, they maintain their love for a certain subject, and continue to spend time and energy to complete the research project, they continue to maintain their love and curiosity, they will not feel bored in the research process, and even love the field more.

In general, the Nobel Prize has become the standard for judging the best in a field, but many scientists have not had time to win the Nobel Prize, but they still maintain their love for their careers. Even though they encountered various difficulties in the research process, they did not regret their decision and were obsessed with the same field.

Because scientists have a desire to win. They all want to figure out how many others they have so that they can be immortalized.

It may be that you want to make some breakthroughs in this area, and once you insist on something, you will not choose to give up easily.

The reason why scientists are so persistent is because the algorithm of pi is ingenious and has infinite secrets.

<> there is no reason for it, it's just people's curiosity!! We've all wondered: The chicken or the egg?

Does the universe have boundaries? ......All these questions come to anyone, and there is no final answer, because no one knows. According to the definition of number, there is no maximum and no minimum number.

Then if pi is exhausted, it means that it is a definite number, and it is no longer an unknown number. In fact, mathematics is a very wonderful subject, and a lot of its infrastructure cannot be proven, it is just a human rule. And mathematics is also the strictest, so many conjectures are difficult to prove, because in the huge mathematical edifice, there is a number that comes out to disprove this conjecture.

But then again, even if pi is exhausted, it will not have any effect on the present, because the error is too small, and there is nothing in the world that is completely free of error, and when the error is small, it can actually be ignored.

However, everything is changing, and there is no absolute truth, so let's explore it together! As we all know, the decimal point of pi is followed by an infinite non-cyclic decimal place, life is limited, but scientific exploration is endless, the higher the accuracy of pi, the smaller the error, the closer to the truth, the more it can reflect the purpose of scientific exploration and the meaning of scientists' lives. Because pi represents the degree of the circle, if it can be calculated to the end, it proves that there is an absolute circle, that is to say, the world is not composed of particles, because as long as it is composed of particles, it is not an absolute circle, if it is not composed of particles, it means that the derivation model of human beings inside the atom is wrong, not to mention quantum mechanics, that is also wrong, so only if pi is calculated forever, infinitely, can it be said that the particles in this world can be infinitely differentiated.

It can be differentiated all the way down to the most basic particle defined by humans: quantum. This quantum also represents the artificially defined absolute fundamental particle.

This is because scientists believe that pi is very useful and can solve many mathematical problems, so they are still working on it.

Because they want to crack the secret of pi, they want to study it, and they want to understand how it is calculated.

This is done in order to perform better calculations, avoid errors, and make the data more accurate, which plays a very important role.

Because scientific exploration is endless and never-ending, doing so can make the accuracy very high and can reduce errors.

It is a fast and accurate Wang Lichang algorithm that is looking for a finite number of calculations of pi.

It should continue to be calculated, there will definitely be an end, otherwise the circumference is there, the diameter is also there, and it is all fixed, why is pi not a fixed number???

The more accurate the calculation, the greater the research in the fields of aerospace and military. This reflects the improvement of the country's overall strength level, and the other is to contribute to scientific research.

This is a comparison of the speed and ability of computers to process data.

Pi is the most understandable irrational number, and it is expressed that pi can now be calculated to 600000000000000000000000000000000000000000000000000000000000000000000000000000000000000 If you use other concepts, such as function operations for blockchain technology, do ordinary people understand what it means?

Any scientific problem that is studied to the extreme will inevitably become a philosophical question, why do we have to calculate pi in the first place, because we want to know where humanity is going, just as the universe is unquestionable, quantum is unmeasurable, space is unknowable. Whether these questions are science or philosophy Who can I.

Do you know the accuracy of satellite positioning now? The method used is that your device transmits signals to at least three satellites, and the satellites then feedback the signal, according to the length of time that the signal feedback is received as the radius, draw three circles, and the place where these three circles intersect is your position, this calculation method is not so simple as it seems, the speed of the signal is also directly related to the radius of the circle, the more accurate the data calculated by our system, the smaller the position error of the result, so now the satellite calculation is dozens of decimal places, hundreds of places, which involves piThe more mantissa there is, the more accurate the data provided, and the smaller the error, even if it is a difference of one ten-thousandth of a millisecond, the optical signal will be a few meters or tens of meters.

On the surface, it is a numerical value, but the real meaning is to compete with the computing power of large-scale computers, and to compare industrial science and technology.

Thirty trillion digits (number) is a very large number in the eyes of human beings, but in fact, it is not worth mentioning in the universe. The universe (matter) that we observe only makes up a very small part of the total mass of the universe, and cannot be expressed by numbers. The universe is infinite, and so are the numbers!

Thirty trillion is only thirty trillion trillion billions of a certain number....One in one. People are so worthless in the universe that one pi can turn people into a daze! Humanity will continue to count.

Why? Proof of human existence.

What are the benefits of such laborious calculations? In addition to proving the existence of human beings, it is also promoting the development of human brains and the progress of science and technology, which is a good source for the development of society. But is this progress and development good for humanity? Who knows?

From birth to death, it is a road of no return, and I do not know whether the development of science and technology will benefit mankind or whether it is a road of no return. Who knows?

In fact, the calculation of the number of digits after pi is very closely related to it, and it is more obsessed with the teachings, because pi has a very close relationship with the universe.

If pi ( ) is exhausted, then it proves that pi ( ) is a rational number and not an irrational number. The so-called "circle" is completely equal to a "regular polygon", there is no real circle, and the smooth surface of the circle is countless small line segments. It also proves that curves do not exist, and that the curves that were previously thought to be wrong are all wrong, and that the figures in geometry will become chaotic.

As a result, the calculation of the area covered by curves in calculus is also wrong, and calculus will be turned upside down, which will have a drastic impact on the field of mathematics. And once it is proved that calculus is wrong, then the integrated circuits made by modern people using calculus will not exist, and all the electrical equipment they make will be wiped out.

Introduction to Pi:

Pi is the ratio of the circumference of a circle to its diameter, generally represented by Greek letters, and is a mathematical constant that is prevalent in mathematics and physics. It is also equal to the ratio of the area of the circle to the square of the radius, and is the key value for accurately calculating the circumference of the circle, the area of the circle, the volume of the sphere and other geometric shapes. In analytics, it can be strictly defined as the minimum positive number x that satisfies sinx = 0.

Pi is represented by the Greek letter (pronounced pa) and is a constant (approximately equal to, representing the ratio of the circumference to the diameter of a circle. It is an irrational number, i.e., an infinite number that does not follow the decimals of the liftoff ring. In daily life, it is common to use the representative pi to approximate the calculation.

Nine decimal places are sufficient for general calculations. Even the most sophisticated calculations for engineers or physicists can be taken to a few hundred decimal places.
