In the 16th century, the German mathematician Rudolph spent his whole life calculating pi to 35 decimal places, which later generations called Rudolph's number, and after his death, others engraved this number on his tombstone. After his death, the Swiss mathematician Jacob Bernoulli, who studied the spiral (known as the thread of life), was engraved on his tombstone with a logarithmic spiral, and the inscription reads: "Although I have changed, I am the same."
It's a pun that both portrays the nature of the spiral and symbolizes his love for mathematics.

Gauss's father worked as a foreman in a masonry, and he always had to pay his workers every Saturday. In the summer when Gauss was three years old, one time when he was about to pay his salary, little Gauss stood up and said, "Dad, you are mistaken.
Then he said another number. It turned out that the three-year-old little Goss was lying on the floor, secretly following his father to calculate who to pay and how much to pay. The result of the recalculation proved that Gauss Jr. was right, which stunned the adults standing there.

One day, the French mathematician Pu Feng invited many friends to his home and did an experiment. Pu Feng laid out a large white paper on the table, and the white paper was full of parallel lines at equal distances, and he took out many small needles of equal length, and the length of the small needles was half the length of the parallel lines. Pu Feng said:
Please put these little needles on this blank piece of paper and feel free to do so! The guests did as he was told.
This number is an approximation of . An approximation of pi is obtained each time, and the more times you throw, the more accurate the approximation of pi will be. This is known as the "Pufeng Experiment".

One summer day in 1981, a mental arithmetic competition was held in India. The performer is a 37-year-old woman from India whose name is Shaguntana. On that day, she had to compete with an advanced electronic computer with amazing mental arithmetic skills.
The staff writes a large number of 201 digits and asks you to find the 23rd square root of the number. As a result, it took only 50 seconds for Shaguntana to report the correct answer to the audience. In order to arrive at the same number of answers, the computer has to input 20,000 instructions and then calculate them, which takes much more time than Shagontana.
This anecdote caused an international sensation, and Shagontana was called the "mathematical magician".

There are too many typos, and life is a non-stop!

Have you heard the story of Gauss adding from 1 to 100?

I think why not find someone who types very quickly.

On May 29, 1832, the young and vigorous Galois of France planned to duel with another man for the so-called "love and honor". He knew that his opponent's marksmanship was good, and his hope of victory was slim, and he was likely to die. How will he spend this last night, he asked?
Prior to this, he had written two mathematical essays, both of which were contemptuously rejected by the authorities: once by the great mathematical debater Cauchy; Another time was the sanctification of the French Academy of Sciences that something in his head was valuable. Throughout the night, he spent his time in a flanking state of writing his last words in science.
Write as soon as possible before death, and write as much as possible about the great things in his rich thoughts. From time to time, he interrupted, writing "I don't have time, I don't have time" in the margins of the paper, and then went on to write an extremely sloppy outline.
What he wrote in the last hours before dawn found once and for all the real answer to a problem that had tormented mathematicians for several generations, and inaugurated an extremely important branch of mathematics, group theory.
The next morning, in the dueling ring, he was punched through the intestines. Before he died, he said to his brother, who was crying beside him: "Don't cry, I need enough courage to die at the age of 20."
He was buried in the ordinary trench of the cemetery, so today there is no trace of his grave. His immortal monument is his writings, consisting of two rejected **s and a scribbled manuscript he wrote that sleepless night before his death.
The mathematician Problem Fermat was a member of the Parliament of Toulouse, France in the 17th century, an honest and hardworking man, and at the same time the most prominent mathematical amateur in history. During his lifetime, he bequeathed to posterity a large number of extremely wonderful theorems; At the same time, due to a momentary negligence, it also posed a serious challenge to later generations of mathematicians.
Fermat had a habit of keeping the results of his thoughts short when he was reading. At one point, while reading, he wrote something like this: "....It is impossible to divide a power higher than 2 into two powers of the same order.
I'm sure I've found a wonderful way to do this, but unfortunately the blank space here is too small to write. This theorem is now named "Fermat's Great Theorem", i.e., it is impossible to satisfy xn yn = zn This is Fermat's challenge to future generations.
In order to find the proof of this theorem, countless mathematicians in later generations launched one charge after another, but they were all defeated. In 1908, a wealthy German man offered a huge reward of 100,000 marks for the first person to fully prove Fermat's theorem. Since the theorem was proposed, mathematicians and Qingchong have struggled for more than 300 years, but they still have not proved it.
But this theorem definitely exists, and Fermat knows it.
Mathematically, Fermat's theorem has become a mountain higher than Mount Everest, and human mathematical wisdom has only once reached such heights, and since, it has never been reached.

The story of Archimedes.
King Heelous of Syracuse asked a goldsmith to make a crown of pure gold, and because he suspected that it was mixed with silver, he asked Archimedes to identify it. When he entered the tub to bathe, the water overflowed into the tub, and he realized that objects of different materials, although they weigh the same, must not drain the same amount of water because of their different volumes. Based on this reasoning, it is possible to determine whether the crown is adulterated or not.
In 1785, at the age of 8, Gauss was in the first grade in an elementary school in rural Germany. >>>More
The great mathematician of the Northern and Southern Dynasties, Zu Chongzhi, calculated pi to the seventh decimal place. It is proved that pi is located between and . More than a thousand years before the Europeans got the same result.
The Pythagoreans of ancient Greece believed that any number in the world could be expressed as an integer or a fraction, and made this one of their creeds. One day, one of the members of this school, Hippasus, suddenly discovered that the diagonal of a square with a side length of 1 was a strange number, and he studied it diligently, and finally proved that it could not be represented by integers or fractions. But this broke the tenets of the Pythagoreans, and Pythagoras ordered him not to spread the word. >>>More
