It is said that everyone can find their birthdays in pi, is it true?

Pi is the ratio of the circumference and diameter of a circle, which has a pivotal position in mathematics and physics, and our country's Zu Chongzhi was the first person to accurately reduce pi to seven decimal places.

Although the current computer has accurate pi to a trillion decimal places, even in the field of physics, which requires extremely high accuracy, pi is accurate enough to be within 100 digits, so the calculation of pi is of little practical significance, more to test the performance of supercomputers and satisfy human curiosity.

Although many people know that pi is an infinite non-cyclic decimal, what few people know is that there is a "transcendent number" behind the identity of the infinite non-cyclic decimal of pi

Pi as a "transcendent number", the probability of occurrence from 1 to 9 is completely random, plus pi itself can be infinitely extended, so some people say that "everyone's birthday, ID number and mobile phone number, bank card number and bank card password can be found in pi".

In fact, it is not surprising that pi has such characteristics, after all, its infinite non-cyclic and transcendent nature has proved that it can contain "all the combinations of numbers that have appeared and all have not appeared throughout the ages", each of our mobile phone numbers is just a permutation and combination of 11 digits, and the bank card number is just a permutation and combination of 19 digits, theoretically as long as the computer performance is powerful enough, we can retrieve everyone's ID number and bank card number from the sea of numbers.

At present, it has been determined that all 6-digit number combinations and all 8-digit number combinations can be found within 1 billion decimal places of pi, and there are now ** to provide birthday and bank card password query services in pi.

There are two other stories similar to pi, namely "Infinite Monkey Typewriter" and Liu Cixin's "Poetry Cloud", the former assumes that if there are infinite monkeys and infinite typewriters, these monkeys will sooner or later type out human literature, while Liu Cixin tells the story of a god-level civilized individual who hopes to "surpass Li Bai" in "Poetry Cloud".

At the end of the story, the way for the god-level civilization individual to surpass Li Bai is to use technology to try all the permutations and combinations of Chinese characters, so that all the poems before and after have been written, and there must be poems that surpass Li Bai's works.

Pi is a magical number algorithm created in this world, which contains all the numbers in this world, so you can find everyone's birthday in pi.

It is said that the birthday of all people can be found in pi, which is true, and this should be studied by mathematicians, and the person's birthday and mobile phone number can be found in the decimal of the roundness, which should be possible in theory.

Pi is an infinite loop of numbers, and now scientists have calculated billions, or even hundreds of billions, using supercomputers, and under the combination of so many numbers, there is naturally a considerable probability that they can find the number corresponding to everyone's birthday and personal information.

As we all know, pi is an infinite non-cyclic decimal number, and from one to nine, all numbers will appear in it, so it is indeed true that everyone can find their birthdays in pi.

Pi is particularly magical, and being able to find out everyone's birthdays is actually a very powerful, special arithmetic method is very accurate, and it is breathtaking.

Then enter pi.

For your birthday, click [Peking University School of Mathematics. people].

Once you're in, enter your date of birth at the bottom and click Send.

Finally, you can check the position of your birthday in pi, which is the ratio of the circumference to the diameter of the circle, usually in Greek letters.

Denote. It is an infinite non-cyclic decimal.

Tens of trillions of decimal places have been calculated. Since there are infinitely many numbers after the decimal point, there must be an infinite number of combinations of numbers. Have you ever wondered if you have your own combination of birthday numbers or QQ number in Pi?

Combo and phone number combo? Where does this number combine?

Today I am going to share a small software to easily solve your doubts.

This software is called "Pi Query", and the size of the installation package is just over two trillion.

Install this software on your phone and open it.

It can be seen that the number is combined to the 108563704 decimal place.

Try the second function again and find out what the first hundred million digits after the decimal point are.

You can know what the hundredeath billionth place after the decimal point is.

Pi is an infinite non-cyclic decimal number, so just look for a birthday number that meets the criteria.

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 common 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 263 AD, the Chinese mathematician Liu Hui used the "circumcision" to calculate pi, he first connected the regular hexagon from the circle, and then divided it one by one until the circle was connected with a regular 192 sides. He said: "If you cut it finely, you will lose it, and if you cut it again and again, so that it cannot be cut, it will merge with the circumference and lose nothing."

This encompasses the idea of finding the limit. Liu Hui gave an approximate value of pi of =, and after obtaining pi =, Liu Hui tested this value with the diameter and volume of the copper volume measurement standard Jia Lianghu made in the Han Dynasty in the Jin arsenal, and found that this value was still on the small side. So I continued to cut the circle to the 1536 polygon, and found the area of the 3072 polygon, and obtained a satisfactory pi equal to about that.

Around 480 AD, Zu Chongzhi, a mathematician during the Northern and Southern Dynasties, further obtained results accurate to 7 decimal places, giving insufficient approximations and excess approximations.

The advent of electronic computers has led to the rapid development of value calculation. In 1949, the world's first American-made computer, the ENIAC, was opened at the Aberdeen Proving Ground. The following year, Ritweissner, von Newman, and Medropless used the computer to calculate 2,037 decimal places.

The computer did the job in just 70 hours, and after deducting the time it took to insert the punch card, it equates to an average of two minutes to calculate a single digit. Five years later, it took IBM NORC (Naval Ordnance Research Computer) just 13 minutes to calculate 3,089 decimal places. In the 60s and 70s of the 20th century, as computer scientists in the United States, Britain and France continued to compete in computers, the values became more and more accurate.

Pi is infinite, and it is theoretically possible to find your birthday number, it is possible to find it at the beginning, or it is possible that you have searched for it all your life and have not found it.

Pi so many digits can certainly find itself angry.

Teach you how to find your birthday in pi.

Empirical address.

It's a lot of fun to play, and it's very easy to look. You only need to pay attention to WeChat*** "Peking University Mathematics Academy", and send your birthday date in the form of 8 digits in the input box, and you can check that your birthday date is a few digits after the decimal point of pi. However, not all friends can find the number of digits of pi, and some friends will display "You can't find your birthday in the first 200 million digits......On March 14 every year, the Teachers and Students Association of the School of Mathematical Sciences of Peking University held an event to celebrate the day, which is also the "International Mathematics Day".

2. Why does Pi have everyone's birthday?

That is, pi, which is the ratio of the circumference of a circle to its diameter, which we know by heart, but it is more than that. Pi The number after the decimal point can be calculated forever, endlessly, and without repeating. The number of pi is still being calculated, and as of 2019, Google's supercomputer has been calculated to a trillion decimal places!

So in this string of numbers, there are all kinds of possible combinations, not only can you find your birthday, but also passwords, card numbers, etc., if you say that it corresponds to letters, you can find every word, even the name you are familiar with, etc., all in this pi.

3. There is no end to pi.

This problem can be said to be unexplainable, at least for now. The calculation of pi is still in progress, and because of the development of modern science, supercomputers have helped to calculate to hundreds of millions of decimal places, but it has not been finished until now, and it seems that there is no end in sight. It is said that once the calculation of pi is exhausted, it may mean the collapse of the mathematical system, and the science based on mathematics for all mankind will be questioned!

But the world will not be destroyed, because even if it can be counted, it is accurate enough!

My birthday appears at number 16,522,519. We all know that it's an infinite non-cyclic decimals.

So the permutations and combinations of various numbers.

You can find it all above.

It's like it's very popular to check the number of your birthday, because it's impossible for me to memorize all the decimal numbers in my daily life, not to mention that the decimal number behind is infinite. Therefore, it has become a very romantic thing to check the birthday of your favorite. Some people will choose to slowly find the place of the birthday after the decimal point, and some people will follow some small programs.

One-click generation. Anyway, not many people really arrange decimals, so even if the above of the Mini Program is inaccurate, we just need to have this happy process.

Nowadays, more and more young people are starting to pursue a romantic life. Every year, I hope that I can receive a bouquet of flowers or a beautiful small gift. In fact, the purpose of these things is not to make girls happy, but to allow girls to post gifts on social platforms, so as to gain a sense of vanity.

So, when a girl takes the initiative to share the dynamics between you, it means that the girl likes you, and if the girl always avoids the topic, it means that maybe you are just her spare tire.

When we check the number of our birthdays, we all need to use a ***. This makes me wonder if it's such a promotional activity made by this *** in order to attract fans, after all, most people's curiosity is still relatively strong. Of course, there are some people who feel that there is no need to look this up, because it will not affect our lives and will waste time.

After all, the ranking does not determine whether the person is good or bad.

But I feel that this inquiry can only be used as a spice in our lives. It adds a little fun to our boring life. If you don't like it, you don't have to check it, and don't complain about the people who like to follow the trend on the Internet.

My birthday is in the top 1 and since my birthday is 3, I think my birthday number is very high, you guys are in the first place.

My birthday is 8th. I think this phenomenon is very good because it allows many people to recognize pi and remember it.

My birthday is in 22nd place, but it's normal, and it's good to be on the list.

Ranked 49886846, and this ranking table is found according to the ranking order of the year, month and day.

I think it's amazing, and I've been able to find out how many digits my birthday has in pi.

Can Pi really find everyone's birthday and bank card password? Don't believe it.

Pi is an infinite loop of numbers, and now scientists have calculated billions, or even hundreds of billions, using supercomputers, and under the combination of so many numbers, there is naturally a considerable probability that they can find the number corresponding to everyone's birthday and personal information.

It is said that the birthday of all people can be found in pi, which is true, and this should be studied by mathematicians, and the person's birthday and mobile phone number can be found in the decimal of the roundness, which should be possible in theory.

*b!Take off your pants and fart! You can find people all over the world directly in the ten Arabic numerals!

Inevitable! Human birthdays are finite, and pi is infinite.

No, I'm a first-grader and I've never learned pi.

Yes. It is an infinite non-cyclic decimals. Sure to match the number that corresponds to your birthday.

When pigs fly. 20000101 this kind of thing will definitely not be found.

It's impossible to drop that my birthday is November 11th, can I find 1111.

Pi can find your birthday.

In mathematics, pi (pi) is an irrational number, and the number expression is, which is an infinite non-cyclic decimal place, and although it has an infinite number of digits, there is an interesting fact: in this infinite string of numbers, any number or date, even your birthday, can be found. Let's talk about this interesting fact, if you don't know much about pi, then you need to know these things.

Pi is a mathematical constant that represents the ratio of the circumference of a circle to the ratio of lead to diameter. That is, if we know the diameter of a circle, then we can calculate its circumference from pi. However, pi is not just a numerical constant, it also involves a lot of interesting mathematical problems.

For example, we've been trying to calculate the exact value of pi, but since it's an infinite non-cyclic decimal number, we've never been able to get its exact value.

Even if we use the most powerful computer, we can only calculate a certain number of digits of pi. But surprisingly, even though the length of the number of pi is infinite, it still contains an infinite amount of information.

One of the failures is our human birthday. As I mentioned earlier, no matter what the number of your birthday is, it is possible to find it in Pi. This means that if we look inside pi, we will definitely find a string of numbers that are exactly the same as the number for our birthday.
